Dams and Tunnels Site Investigation: Downhole Test using Borehole Televiewers and Pressuremeter
Projects involving dams and other hydroelectric infrastructure, such as shafts and tunnels, have a high geotechnical risk and are often located in remote, mountainous terrain so that application of high resolution, portable geotechnical equipment offers highly effective solutions to help de-risk a ground engineering project. Our experience is that the use of these tools always improves the accuracy in the interpretation of ground conditions and very often provides a much more accurate representation of ground conditions over conventional drilling. This is because the tools measure the drillhole wall which is undisturbed relative to the core which might be highly disturbed due to drilling mechanics. The advantages are more accurate design, better understanding of ground and often a better project price. RDCL’s wireline geophysics equipment is highly portable and well suited for these projects, which include the identification of suitable hydroelectric sites, and fracture detection, prior to tunnelling (vertically and horizontally). Our acoustic and optical televiewers create very detailed imagery of rock structures which combined with our high capacity pressuremeter for in-situ measurement of rockmass modulus, greatly assists design and the evaluation of ground risks. Why and What are Borehole Televiewers? Televiewers provide a continuous, orientated, high-resolution image of the borehole wall, often superior to conventional core logs, which offers many advantages to geologists and geotechnical engineers,. The data provides repeatable, checkable information about geology, structure, fractures, stress orientation, provides depth control where core recovery is poor and importantly allows orientation of structures even where ground conditions are poor. How Borehole Televiewers Work The acoustic televiewer logs the borehole wall in terms of hardness, measuring the amplitude of a high frequency sound wave. Hard rocks reflect high-amplitude signals and soft rocks and fractures reflect low amplitudes. The individual measurements of reflected amplitudes are made continuously by a rotating a 360° transducer. The result is a map of the borehole wall with an individual resolution of about 2mm in ideal conditions. Acoustic Televiewer (ATV) data is aligned with magnetic north. Fractures and bedding planes appear as sinusoidal lines where the deepest point on the line is the direction of dip. Tool centralisation is important to ensure similar travel time and signal strength in all directions. Data resolution reduces with wider diameter boreholes, and in some cases thick drilling mud due to signal dispersion. Because the acoustic televiewer is sensitive to rock hardness and can measure fracture orientations and apertures (lost in drill core), it has become an important geotechnical tool in both sedimentary and hard-rock formations. Acoustic televiewers most often in fluid filled holes to ensure the sound wave can travel through medium. If data is required from dry boreholes (above the water line), the Optical Televiewer (OTV) should be employed. It measures the colour and shade of reflected light, basically a 360°camera. The borehole wall is lit by a ring of diodes on the tool and reflections are directed to a light-sensitive sensor via a conical mirror. Resolution is very high, with pixel sizes down to well below 1mm at HQ borehole diameter. The optical televiewer provides an orientated photograph of the borehole wall at high resolution and without perspective. The system does not offer a travel time image, and log quality is dependent on clean borehole fluid if it is run below the water table. In slim holes, optical televiewer images can be of such high quality and value that it is usually worth flushing the borehole to remove mud from walls and replacing dirty fluid before logging. Subsurface Data Output and Characterization using Televiewers • Characterise ground conditions in terms of condition, stiffness, fractures and lithology • Gain an understanding of the groundwater conditions • Investigate the condition of existing structures associated with dams and tunnels Borehole Televiewers + Pressuremeter Test The Pressuremeter provides an indication of rockmass deformation modulus by inflating a bladder in a borehole to pressure the walls, with strain measured by strain gauges. The tool is suitable for soft rock and hard rock. These characteristics are for the design of important structures such as underground openings, and pile foundations for bridges and high-rise buildings. Pressuremeter tests provide parameters to assess stability, rock mass deformability (creep, rebound and permanent characteristics) that all feed into designs for tunnel linings, concrete dam foundations, bridge supports and lateral deflection analysis shafts. Borehole televiewers and pressuremeters are cost effective portable systems that provide on-site geological and geotechnical data in real time outputs and processed outputs. RDCL’s downhole technologies provide effective rapid deployment for engineering design, works during construction and monitoring throughout the structure’s life. Battle Proven Technology The Philippines are one of the leading countries in the development of dams and tunnels in the Southeast Asian region. RDCL are based in Manila with staff and equipment. This means we can respond fast, mobilizing for domestic projects effectively and safely during a time when the world is restricted by global travel. From Run-of-River hydroelectric systems, concrete dams, bulk water storage, pumped storage, mine tailings dams, subway tunnels and regular geotechnical applications, both the televiewer and pressuremeter has proved to be reliable and invaluable tools.

Making Mining Smarter Through Virtual Twins
Article by Engr. Jeffrey Q. Geronimo In the recently concluded 2021 Prospectors and Developers Association of Canada (PDAC) convention, global leaders in mining have all agreed that the key to reduce risks and create more value in mining is by testing everything in the “virtual world” first. This is particularly done by taking risks, failing, and learning from mistakes -- not just digitally but also virtually. DIGITAL TWIN VS VIRTUAL TWIN “Digital twin” is not a new concept to the mining sector as computer-aided programs such as 3D CAD models have already been existent and utilized for several decades. However, while we have experienced vast improvements and upgrades, these models are still isolated from the real world and remains to be just digital models. This is where the concept of “Virtual twin” experiences come into play. It is a great leap beyond the digital twin experience wherein more accurate and scientific real-world models are taken into consideration such as time, environment, and behaviors in varying conditions and scenarios. This will enable problems and solutions of the company to be communicated faster to different teams across the mining value chain -- thereby increasing the company’s understanding, collaboration and participation. TAKING THE GREAT LEAP Mining companies may already have the fundamental data, processes, and infrastructure they need to begin the shift. What they may be lacking is the state-of-the art connectivity, contextualization, and collaborative platform that will integrate all of its people, processes and data. This will be their portal to the virtual twin experience. This is where the GEOVIA Mining Intelligence suite powered by the 3DEXPERIENCE Platform may bridge the gap. It provides users with an overall view of their mining operations with ultra-fast access to information on top of easy and sophisticated analysis. THE INTELLIGENCE NEEDED BY A SMART MINE The 3DEXPERIENCE Platform connects GEOVIA users with role-based applications to connect people, ideas, data and solutions in real-time. It enables centralized control and viewing of mine data, providing a single source of truth on your business operations. Moreover, it allows efficient collaboration with traceability across the mining value chain The GEOVIA Mining Intelligence suite, consisting of Production Intelligence and Geology Intelligence functions, extends the promise and collaborative power of the 3DEXPERIENCE platform by allowing users to reveal, measure and analyze mining data so that they may deeply understand and improve mining operations. GEOLOGY INTELLIGENCE “Geology Intelligence” is part of the Mining Intelligence offering. By simple configuration, it can show block model data in a graphical and tabular format. In addition, it gives emphasis on important information by using graphical techniques and drilldown into information to see more detail. Moreover, it analyzes these geological data and plot these as a chart. An overview of a geological data analysis using the Geology Intelligence function. PRODUCTION INTELLIGENCE Monitor equipment performance: Many mining companies measure their equipment performance metrics through spreadsheets and creating charts manually. While it gets the job done, this tedious process does not easily permit detailed analysis or comparison with historical performance to aid decision making. With the “Production Intelligence” function bundled with the GEOVIA Mining Intelligence suite, equipment performance metrics can now be configured around the mine’s specific Time Allocation Model that enables detailed analysis of Equipment Performance. A dashboard of Equipment Performance: Drill Meters, Scheduled Hours and Availability displayed by Production Intelligence. Monitor production actuals against targets: GEOVIA Mining Intelligence aggregates collected data into a more manageable visual representation that assists in making decisions. This will improve business performance and increase profitability. The proprietary 3DEXPERIENCE platform reporting technology uses index files to ensure very quick and responsive reporting. Production KPI and material flow key performance indicators: With a single glance, material flow and KPIs can now be aggregated and presented for an overall view of the mining operation. This is not exclusive to production departments as any other data related to the mine operation such as the mill plant may be displayed. Mine and Mill Plant data are generally always separated from each other due to their information differences. However, with Production Intelligence, it bridges that gap. Material flow showing locations, quantity, material type and more using Production Intelligence. MINING SMARTER TOWARDS SUSTAINABILITY As a step towards virtual twins, we enable a more sustainable mining environment by making it possible to do unlimited iterations, better operational insights, and greater flexibility. It simulates all these value-added services to model complex systems -- making it easier to analyze, test causes-and-effects, and significantly reduce risks faced by mining operations. Let Paramina Earth Technologies, Inc. be your partner towards your virtual twin experience journey.

Ground-Breaking Global Study Unveils the Mental Health Minefield of the Remote Rotational Workforce
Whether on or offshore, the work and lifestyle of a remote rotational worker is unique. While lucrative for some, it has long been associated with a high impact on mental health and wellbeing. A groundbreaking global report from the International SOS Foundation and Affinity Health at Work, ‘Mental Health and the Remote Rotational Workforce’, provides in depth insight into the psychological impacts of this unique mode of working. The new study highlights evidence of the high level of suicidal thoughts, clinical depression, impacts on physical health (such as diet) and the impact of the COVID-19 pandemic on this workforce. Dr Rodrigo Rodriguez-Fernandez, Medical Director Wellness and Non Communicable Diseases (NCDs) International SOS, commented, “There is an urgent need for increased focus, understanding and strategies to mitigate mental ill health and promote better mental health of the remote rotational workforce. This is highlighted in our survey, which uncovers significantly high levels of critical mental ill health issues, including suicidal thoughts and depression. The COVID-19 environment has also added increased stress on this already pressured working arrangement.” Key study findings: 40% of all respondents experienced suicidal thoughts on rotation some or all the time (compared to average of 4-9%). 1 in 5 are feeling suicidal all or most of the time. 29% met the benchmark for clinical depression whilst on-rotation. 52% reported a decline in mood, and their mental health suffered whilst on rotation. 62% had worse mental health than would be the norm in a population. While off rotation, this remains at a high of 31% experiencing lower mental health than the general population. Burn Out The study also exposed that almost a quarter (23%) of the remote rotational workers surveyed experienced emotional exhaustion on a weekly basis. 46% experienced higher stress levels while on rotation and over half (57%) were not engaged in their work. 23% reported that they received no psychological support from their employers. Dr Rachel Lewis commented, “We would expect burn out to be between 2-13% in the general population, so the almost quarter that we see from the survey is particularly high. Burn out can have a serious impact both personally and professionally, on the ability of an individual to carry out their role. Remote rotational work may come with the perks of higher pay, but with its propensity to be isolating at the best of times. On and offshore, working pressures and varying shift patterns also add their weight. And this is not to mention the impact of the current pandemic, which has seen may remote workers unexpectedly away from family and friend networks for longer than anticipated.” Impacts of the COVID-19 pandemic 65% experienced increased job demands. 56% increased working hours stress, anxiety 49% concerned for personal safety (before pandemic?) 1/3 became increasingly lonely 23% had more negative physical symptoms (such as headaches and stomach issues) The Tip of the Iceberg Dr Rodriguez-Fernandez continues, “Mental and physical health are intrinsically linked. Organizations and individuals with a Duty of Care to their remote rotational workers should have visibility and a plan of support for their workforce encompassing both.” Over a third exercised less (35%) 38% experienced worse-quality sleep (38%) Over a quarter (28%) were less able to eat a nutritious diet whilst working On the flipside, the majority of respondents felt that their health and safety was prioritized. They report a strong sense of community and support among co-workers and from managers. Many also felt that they could share their mental health concerns with colleagues. Closer to Home In the Philippines, the Department of Health (DOH) has reported an increase of calls on mental health and suicide through the National Center of Mental Health (NCMH) hotline, with over 3,000 individuals supported during the first quarter of 2021. The Department of Labor and Employment (DOLE)’s supplemental guidelines on workplace prevention and control of COVID-19 issued last year has mandated establishments to implement all necessary safety and health programs at no cost to employees. Dr. Carrianne Ewe, Medical Director at International SOS Philippines shares, “Mental health has been an area of concern for organizations as we continue to navigate through this crisis. We have been supporting our clients with rotational workers by incorporating mental health support into their health and wellness programmes. This has become essential to support employees who are experiencing mental stress and pandemic fatigue. It is important to message that they are not alone in their journey and support is within reach through the Employee Assistance Programmes (EAP) which can help them with sessions on mindfulness and tips on improving one’s mental wellbeing. This approach helps organizations build the resilience of their employees, ensuring that they are healthy and productive during these challenging times.” The full report, including practical recommendations on mitigation measures for companies is now available here.

HMC Support to College Scholars During Pandemic
Contributing to a brighter future for its communities is one of the commitments of Hinatuan Mining Corporation-Tagana-an Nickel Project (HMC), a subsidiary of Nickel Asia Corp. (NAC). One way to uphold this commitment is by providing investments to support education programs. “The commitment to provide support to education is not hindered by the current pandemic, HMC continues to provide assistance to education programs such as: provision of basic school supplies, basic school fees and matriculation, monthly subsidy to day care workers and teachers and support for college students continue”, said Ms. Myline G. Becera, NAC-HMC Community Development Coordinator. “To date, HMC has a total of 19 college scholars. 16 are funded by the Social Development and Management Program (SDMP) of HMC and 3 are funded by Corporate Social Responsibility (CSR)”, said Ms. Becera. Educational Support to College Scholars For Shaina G. Gemparo, 2nd year student taking BS Fishery at Surigao State College of Technology (SSCT) Malimono Campus, the support given by HMC to her education is important. “There are many benefits I get as a college scholar from HMC. First of all, the monthly allowance I receive is crucial for me as a fisheries student studying in Malimono since we have school projects which require me to spend. “Secondly, I am thankful for the boarding house allowance since we need a place to stay in Malimono. Our mode of learning is not entirely remote, from time to time, we are required to meet at school for assignments and projects that require face to face interaction. The support provided by HMC has lessen the burden shouldered by my parents. They no longer need to spend money on my education”, she further added. Debbie G. Gemparo, a teacher by profession, is also thankful for the educational assistance provided by HMC to her daughters. Aside from Shaina, her other daughter Nikki also studies at SSCT Malimono taking up Bachelor of Elementary Education (BEED) is also a scholar of HMC. “I am grateful to HMC for supporting the tertiary education of 2 of my daughters. This is a very big help to our family. Our expenses are lessened since we no longer have to spend much for the educational needs of my daughters since they are scholars of HMC. All they need in school such as basic school fees, place to stay, and food are provided for by HMC”. Support to Remote Learning “As a student during this pandemic, the support provided by HMC is crucial since majority of our classes are conducted online. I use the monthly allowance I receive from HMC to buy WIFI and internet load. Our classes are mostly online, though there are some which require us to meet face to face. I am also thankful for the boarding house allowance of HMC, we do not have to worry where we will stay in Surigao City for classes that we are required to be present physically”, said Angelica P. Laspoña, 1st year student taking up Bachelor of Secondary Education (BSED)at SSCT Main Campus in Surigao City. Jessa R. Gemparo, 1st year student taking up BEED at SSCT Malimono Campus, also expressed her gratitude for the support provided by HMC to her as a scholar. “We use the monthly allowance we receive as scholars for internet to participate in online classes. Some of the allowance we also use as expenses when we need to attend classes in school since not all of our classes are conducted online. Our study is a mix of online and module learning. As of now, the lockdown imposed in Malimono restricts our movement as students, but does not hinder us from improving our knowledge through online learning.” “I am thankful for the opportunity provided by HMC for having me as their scholar. I do not need to ask for assistance from my family to spend for internet connection since HMC provides me with a monthly allowance. Our classes are fully online, we only go to our campus when there are projects and assignments that cannot be sent online”, said Rynelyn Diaz, a 2nd year student of Bachelor of Arts in English Language at SSCT Main Campus in Surigao City. Rodofo Diaz, a fisherman by profession and father of Rynelyn is also grateful to HMC for the scholarship given to her daughter, “The support given by HMC is a big help not only to my daughter but also to my family, Rynelyn is one of my 5 children and she is the only one studying in college.” Lester Plaza, 2nd year student taking BS Fishery at SSCT Malimono Campus, is also appreciative of the support provided by HMC. “Being a scholar of HMC has a lot of benefits, specially financially which is important in remote learning for internet connection to stay online. The monthly allowance I receive from HMC is not only advantageous to me but also to my family. I remember in the past when there was a lockdown imposed in our community as part of the Modified Enhanced Community Quarantine (MECQ) due to local transmission of CoVID-19, we were able to buy food using the monthly college scholar allowance I saved” “I am thankful to HMC for their support, they are always there. They are our guide to help us reach our dreams”, he added.

Reaping the Rewards of World-Class Innovative Technology
Article by: John-Eric Taburada CAGDIANAO, Dinagat Islands -- Good communication is the key to a harmonious and lasting relationship, not just in our homes but also in our working environment. History tells us that because communication and information are both essential to the foundation of all businesses, paving way to the birth of the world-wide-web. The arrival of the internet made the world smaller and made things easier, especially how communication works for many businesses and industries on the entire planet. Surprisingly, some people are still not keen on “high-tech” stuff because they are afraid to go out of their comfort zones, or they are hesitant to invest on unknown grounds. And most of them will just rely on a “wait-and-see” attitude to avoid the possibility of the unknot. This is understandable, to some degree, because jumping to the next curve is viewed as a risky move. This is where Cagdianao Mining Corporation differentiates itself from the rest: it has the courage to take calculated risks and explore the possibilities. In the IT field, CMC -- a subsidiary of Nickel Asia Corporation -- is the pilot for the Point-to-Point (PtP) technology, which is used to connect the internet to remote locations from areas already connected. In deploying this technology, CMC uses Ubiquiti to connect wireless gadgets to other wireless gadgets -- making it the FIRST in the mining industry to utilize this magnificent technology. Some telecommunications or data transfers today still rely on cables and wires. To make the connection accessible to a distance, one still needs cabling resources. The PtP technology increases the company's communication reach further, even if it is located in a remote mining area. This increasing first-rate connectivity is a great help to the success of the organization. Thanks to the vision of our leaders who think more of the company’s future. CMC’s ICT Team is proud to work hand in hand with the improvement of CMC's work environment, and its members take pride in the fact that they work for a technology-pioneering company in the mining industry. As Dave Packard (one of the founders of HP–Hewlett-Packard Company) once said: “I don’t think it’s useful spending much time looking at the past. I think we ought to spend most of our time looking at the future because that’s where we’re all gonna be.” Indeed, this technology is envisioned to provide employees more motivation to work with confidence as they are assured of enhanced productivity, leading to the fulfillment of targeted goals. These are but a few of the rewards that this new technology brings -- and we'll keep reaping more as we discover the efficiencies and other advantages as we move forward. The CMC ICT Team always works in the background among all departments, and its members sometimes feel invisible. Nevertheless, their passion and commitment are felt all around the campsite as they toil in silence. Their mindset and work ethic can be expressed in their slogan: “Our team is MANY HANDS but ONE MIND."

Gold mine in Indonesia installing KREBS® UMD™ Pumps to increase safety
Article by Rachel Johnson A large gold mine in Indonesia set a goal to increase safety. As part of the goal, they evaluated the frequency and risk of site maintenance procedures to find areas where they could make changes. They found that their mill discharge pumps had shorter periods between maintenance events than planned, and researched further to find that the wet end components were not reaching the target wear life. Every maintenance shutdown carried a low level of risk, but in a facility that processes 240,000 tons of ore per day, the frequent maintenance tasks added up to be significant. Site management decided that the time had come to investigate other pump options. The conditions the pumps were operating under were highly abrasive and severe, but management was hopeful that a safer and longer-lasting solution was possible. Safety would remain the top priority in any pump conversion plan, but if the downtime caused by pump maintenance could safely be reduced, the increase in production would be welcome. The mine reached out to FLSmidth to ask if they had any solutions. FLSmidth responded with a proposal for a side by side comparison between the existing pumps and the KREBS Ultimate Mill Discharge (UMD) pump. For the comparison, FLSmidth would install a UMD pump at the discharge of one ball mill. The remaining mills would continue to operate with the existing pumps. During this same period, FLSmidth would set up a trial of different material combinations for the suction liner and wear ring in the UMD pump to make sure that the final recommendation would minimize maintenance events as much as possible. The gold mine agreed to the proposal and FLSmidth installed a UMD 650×550 mm (26×22 in) pump at the ball mill discharge. The pump fed the highly abrasive discharge to a cyclone but it was designed for severe duty applications such as this. A trial was planned in phases to test different combinations of the suction liner and wear ring, with the materials for the impeller and casing remaining constant. At the same time as these materials were to be tested, all components would be compared with the wear experienced by the remaining discharge pumps. Before starting the first phase of the trial, FLSmidth established targets that the life of the suction liner assembly would be 200% of the competitor pump, the life of the impeller would be 220% and the life of the casing would be 102%. At the end of the first phase of the trial, the UMD pump was stopped to evaluate wear. Even wear was seen across the wear ring, but the suction liner showed little wear and could have been used longer. At this point, the suction liner assembly (which includes the wear ring) had already run 306% of the competitor’s suction liner life and with a new wear ring the suction liner could have lasted significantly longer. Regardless of remaining wear life for the suction liner, it was decommissioned to prepare for the second phase with a new wear ring and suction liner material. After the first phase, the impeller and casing had significant life remaining, as expected. These parts had not reached the end of their wear life for the UMD or competitor pumps. New materials would not be tested in the trial so they were left in the pump to continue the comparison. Component Wear Life (%) Competitor pump 24×20 Target Wear Life (%) UMD 26×22 Run 1 & 2 Wear Life (%) UMD 26×22 Run 1 Wear Life (%) UMD 26×22 Run 2 *Suction Liner Assembly 100% 200% 306% 233% Impeller 100% 220% (still running) **see note 270% (still running) **see note Casing 100% 102% (still running) **see note 90% (still running) **see note * KREBS® suction liner assembly contains the wear ring ** Note that the impeller and casing operated in both Run 1 and 2 and are still running. The current wear life percentages are shown in Run 2. At the end of the second phase of the trial, the UMD pump was stopped again to evaluate wear. Significant uniform wear was seen on the suction liner, but the wear ring showed no signs of wear and could be used longer. The suction liner assembly had run 233% of the competitor’s suction liner life and the wear ring could last longer with a new suction liner. The suction liner assembly was decommissioned to prepare for the third phase with a new wear ring and suction liner material. After the second phase, the impeller and casing still had significant life remaining so they were left in the pump to continue the comparison. At this point, the impeller had already lasted 270% of the life of the competitor’s impeller. The casing had so far lasted 90% of the life of the competitor’s casing, and with the wear seen it was anticipated that it also would reach or surpass the target wear life. Phase three of the trial is ongoing and a fourth phase is planned, so the successes presented here will be surpassed as the best material combination for the UMD wear components is determined. Yet, the existing data shows that the UMD suction liner assembly lasts more than three times the life of the competitor’s liner and the impeller lasts more than 2.7 times the life of the competitor’s impeller. The gold mine is pleased with the results they have already seen from the pump comparison and the added safety that they can expect when the trial is complete and they can proceed with converting the remaining discharge pumps. The added financial benefit of an increase in production due to the decrease in maintenance is also appreciated.

Be Confident to Make Good, Timely Decisions During your Nickel and Base Metal Mining Process
With new smart, easy and affordable XRF elemental analysis With extensive mining across the world, many mining companies are challenged with decreasing ore grades. “Geologists need not only reliable but frequent monitoring of the elemental composition of ores; so that they can make snap decisions to accurately predict and optimize recovery rates. This in turn making the extraction and separation of base metals - whether nickel, copper, zinc, a profitable process,” shares Dr Uwe Konig, global mining manager and geologist at Malvern Panalytical. Increase your process efficiency and recovery rate That is exactly why Malvern Panalytical offers comprehensive suite of material characterization tools, a safe, quick, and non-destructive method of elemental analysis known as X-ray fluorescence spectroscopy (XRF). XRF and in particular Malvern Panalytical’s Epsilon range of benchtop spectrometers are widely used by global to small and medium-sized mining companies across the world. Delivering reliable high throughput analysis, so you can be confident to make good decisions Malvern Panalytical’s R&D team has designed a revolutionary model, the Epsilon 4. We are proud that Epsilon 4 combines high analytical performance with low running costs. One of our customers, Ms. Monica Velasco of Berong Nickel Corporation shared, “The Epsilon4 is easy to use. It consistently delivers results according to set standards and is reproducible across different analysis methods. Initial cost is justifiable for the quality of the product. “ “The Epsilon 4 is easy to use. It consistently delivers results according to set standards and is reproducible across different analysis methods. Initial cost is justifiable for the quality of the product,“ says Ms Monica Velasco of Berong Nickel Corporation Notice the significant improvements in sensitivity with the Epsilon 4 spectrum (yellow) compared to our earlier model the Epsilon 3 (blue spectrum) Fast and sensitive Fast measurements are achieved by using latest silicon drift detector technology that produces significantly higher intensities. Unique detector electronics enable a linear count rate capacity to over 1,500,000 cps (at 50% dead time) and a count rate independent resolution typically better than 135 eV for better separation of analytical lines in the spectrum. This allows the Epsilon 4 spectrometer to run at full power, resulting in higher intensities and therefore, giving better data quality, better limits of detection, lesser interference from overlapping elements and a much higher sample throughput compared to traditional EDXRF benchtop instruments. (See comparison with earlier model in Figure 1). Case study: accurate & repeatable measurements of nickel in as fast as 5minutes 25 secondary nickel ore standards containing Ni, Co, Mg, Mn, Zn, Al, Cr, Ca and Si were used to set up the calibration. All elements were measured in air medium. On the left, note that the calibration plots demonstrate good correlation between the given concentrations and the measured intensities. On the right, notice the low standard deviations and high repeatability (Repeatability data missing) achieved. Combining the latest excitation & detection technologies and smart design, this data demonstrates how the analytical performance of Epsilon 4 approaches that of more powerful and floor-standing spectrometers. High throughput analysis with unattended operations of Epsilon 4 The combination of a 10-position removable sample changer with spinner enables the automatic processing of sample batches without the need for operator attention. Continuous rotation of the sample during measurement minimizes any errors caused by non-homogeneity or surface irregularities within individual samples and provides more accurate results. Automatic transfer of data to a central location gives you access to the latest results. Did you know that you can even link the Epsilon 4 to an automation arm for continuous sample loading? Reduce expensive running costs with smart Epsilon 4 technology Little or no expensive sample preparation unlike other traditional elemental methods like ICP or AAS which require long durations of samples digested in acid. Reduce overheads without comprising on performance. The high performance of Epsilon 4 enables many applications to be operated in air atmosphere, without longer overhead time and costs involved for helium or maintenance of vacuum system.

OceanaGold Philippines, Inc. (OGPI) has opened an isolation facility for patients infected with Covid-19 at its host community in Didipio here. The facility is also open for patients from its neighboring villages. Inaugurated last June 15, the Didipio Family Health Center (DFHC) can accommodate up to 15 people with separate room allocations for confirmed cases, suspected cases, and close contacts individuals. The facility is complete with medicine for patients with respiratory problems. It is also equipped with oxygen and rapid antigen test kits. OGPI will also allocate one of its company nurses to take special regular duty at DFHC. Following the inauguration of the facility, the four barangay health workers of Barangay Didipio have already transferred to the newly refurbished DFHC facility. The initiative came following the surge of Covid-19 cases in Didipio and neighboring barangays soaring up to 147 cases since March. In his remarks during the facility inauguration, Mayor Romeo Tayaban emphasized the importance of an established isolation structure while noting the continuous rising of cases in the region. “Let’s make this DFHC useful for the next generation,” he said. The mining company allocated around P1.6 million for the procurement of equipment, medical supplies, and the much-needed repairs of the health facility. DFHC will be operated by the barangay LGU with the supervision of the municipal health office here. Village acting chair Henry Guay, in coordination with MHO and OGPI, is now working on the accreditation of the facility by DOH so that PhilHealth members could avail of their benefits when confined to the facility. Dr. Elizabeth Joaquin, municipal health officer of Kasibu, looks forward to the development of DFHC as a hospital in the future so it can cater more patients even from other areas of Kasibu. Engr. Edgar Rivera, officer-in-charge of OGPI, emphasized the importance of mutual cooperation amon the LGUs, community, and private sector in overcoming the challenges brought about by the Covid-19 pandemic. “As long as OGPI is here, we continue to work with our stakeholders to provide necessary support in the achievement of their goals,” he said. The Covid-19 infections continue to create havoc as more areas outside the National Capital Region become areas of concern. Cagayan Valley was placed under the more restrictive MECQ until the end of the month.

New Report Identifies Major Carbon Reduction Opportunities in Global Mining
New analysis lays out the scale of the mining industry’s energy use and identifies ways it can be reduced using currently available technologies Materials such as copper, lithium and nickel play an essential role in the technologies like electric vehicles and renewables that will help the world meet its decarbonisation targets As demand for these metals increases, the mining industry must itself become more efficient and environmentally sustainable The global mining industry must move away from legacy systems and processes if it is to meet the challenge of decarbonisation, according to a new report released today which calculates mining’s share of global energy consumption and identifies ways the industry can aid the transition to net zero emissions needed to limit temperatures in line with the Paris Agreement. The report, commissioned by the Weir Group plc, analyses mine energy data from over 40 published studies to give a comprehensive understanding of where energy is consumed in mining and minerals processing. It shows that the total amount of power used by the mining industry – which plays an essential role providing the metals used at the heart of the modern economy – is equal to c.3.5% of global energy use. The metals produced by mining are critical for enabling the global transition to low-carbon infrastructure. But without action, energy use in mining itself is set to trend higher in the coming years as demand increases for metals like copper, nickel and zinc. The report suggests there are technologies available today that could make a significant difference to this trend. For example, it highlights that comminution – i.e. crushing and grinding processes – is the single biggest user of energy at mine sites, typically accounting for 25% of mining’s final energy consumption. This is equivalent to the power used by 221 million typical UK homes, or c.1% of total consumption globally. Comminution is therefore a natural target for the most impactful energy savings opportunities. Small improvements in comminution technologies can lead to relatively large savings in both energy consumption and greenhouse gas emissions. For example, a 5% incremental improvement in energy efficiency across comminution could result in greenhouse gas emissions reductions of more than 30m tonnes of CO2-e. The replacement of traditional comminution equipment with new grinding technology also reduces indirect emissions in the mining value chain, for example by removing the need for the manufacture of emission-intensive steel grinding balls. Of the remaining energy consumption by the mining industry, diesel in varied forms of mobile equipment accounts for 46%, electricity in mining (ventilation) 15% and “other electricity” 14%. Other significant opportunities identified by the report for reducing mining’s energy consumption include optimisation, big data and artificial intelligence. In addition, if zero emissions energy sources are deployed for mining equipment – e.g., renewable energy, energy storage and alternative fuels – then the industry may well be able to achieve zero emissions, leaving a relatively small role for offsets and carbon credits to play. The report comes as the mining industry is under ever-greater pressure to produce essential minerals that support some of the biggest global structural trends, from population growth to urbanisation and decarbonisation. Copper, nickel, steel and lithium are core components of electricity transmission and storage, electric vehicles and renewable energy infrastructure. The move to a decarbonised economy will result in increased primary consumption of these mined commodities, even after factoring for recycling, so it is important that mining itself becomes more sustainable. Download the independent Mining Energy Consumption 2021 report here: www.energysavingsinmining.com Commenting, Weir Group Chief Executive Jon Stanton said: “The mining industry is central to economic development globally, with critical minerals enabling the low-carbon transition required in the rest of the economy. But the environment in which it will operate in future will be very different from the past, requiring comprehensive change and investment. In short: mining needs to become more sustainable and efficient if it is to provide essential resources the world needs for decarbonisation while reducing its own environmental impact.This report is an important contribution to that debate which we hope will spark thoughtful conversations around the world on the way forward.” Alison Keogh, Chief Executive of the Coalition for Energy Efficient Comminution, said: “This report highlights both a challenge and an opportunity to revitalize cross-industry discussion and actions on decarbonisation and ESG solutions. We invite industry leaders to actively contribute and collaborate through mining-vendor-research partnerships and share knowledge. Together, we can accelerate improved energy, emissions and water footprint across industry faster.” Ricardo Garib, Weir Minerals Divisional President commented: “Weir Minerals is focused on making mining more efficient and sustainable by leading technology change in the industry. Our Enduron HPGRs are increasingly replacing conventional milling systems in comminution (crushing, screening and grinding) circuits because of their substantially lower energy consumption, finer rock reduction requiring less water downstream and potential for significant total cost of ownership reductions.” Stuart Hayton, Managing Director of Weir Minerals Netherlands, where the Enduron® HPGRs are designed and manufactured, added: “Not only do Enduron HPGRs require as much as 40% less energy than traditional alternatives, their wearable components last much longer and the maintenance time required to replace worn out parts is significantly lower. The estimated carbon saving of each Enduron HPGR in operation is equivalent to taking more than 3,600 petrol fuelled cars off the roads each year.” Notes: The report quantifies energy use in five commodities: copper, gold, iron ore, nickel and lithium. Bringing together mine energy use data from more than 40 published studies (each of which references dozens more studies) from 2007 to 2020 into a single narrative, the report aims to build a more comprehensive understanding of energy use in the mining industry. Using the current production rates of the commodities in question, and the energy intensities for each of the commodities, a total of 1,68 EJ/a (1,680,000,000,000,000,000 joules per year) has been calculated. This is approximately 0.5% of total final energy consumption globally. Published information indicates that the entire mining industry consumes approximately 12 EJ per year – or 3.5% of total final energy consumption globally. Assuming that present trends continue, there will be 250m electric vehicles on the road by 2030. To meet this demand, production of cobalt, lithium, graphite and nickel will need to be scaled up significantly. Current projections show that the current rate of decarbonisation globally is far below what is required to meet the goals of the Paris Agreement. A sustained decarbonisation rate of up to 7% per year, year on year should be sufficient to achieve the goal of a temperature increase of well below 2°C by 2100. For the mining industry, there are multiple ways to achieve decarbonisation including energy efficiency and fuel/energy switching. Many of these opportunities are starting to be explored by both the mining companies and the mining services providers, who see decarbonisation and energy reduction as a key way to reduce exposure to the risks of climate change.

Sandvik introduces New Toro™ LH410 Loader, the Next Member of its Toro™ Family
Both in terms of launching new equipment and introducing upgraded versions of existing models, Sandvik is getting ready for an eventful loader and truck year 2021. The first exciting acquaintance of the new year is the totally renewed Toro™ LH410, a versatile and capable underground loader with 10 tonnes payload capacity. Proven performance boosted with new features The new Toro™ LH410 loader builds on the best parts of its predecessor, the successful Sandvik LH410. However, following the footmarks set by Sandvik’s large intelligent loaders, the now introduced Toro™ LH410 is full of new features, making it in practice a totally new machine. Toro™ LH410 offers best in class performance in productivity e.g. by means of high ramp speeds and fast bucket filling, and to make truck loading easy, it features superior lift height compared to any other loader of the same size class. The renewed loader features Sandvik Intelligent Control System, with a 7" touch screen display as a user interface, enabling multiple new options to tailor each loader according to customer needs. Mid-size dimensions – full-size intelligence “With all its features, this truly is an advanced and intelligent piece of equipment, definitely comparable to the large i-series loaders – but naturally in a smaller package,” says Kimmo Ulvelin, Product Line Manager Small and Low Profile Loaders at Sandvik. “We want to offer our customers possibilities for sophisticated and intelligent equipment also in the middle size class; and therefore Toro™ LH410 has the same Sandvik Intelligent Control System as the large Toro™ LH517i and Toro™ LH621i loaders, with the available traction control, operator speed assist and integrated weighing system, to name a few. “Also, Toro™ LH410 is fully compatible with AutoMine® solutions. From new features specifically relating to safety, we could mention e.g. a new retrieval hook, updated door interlock, improved access ways, and new type of fire suppression system options.” Full range of engine options The engine range of the Toro™ LH410 loader includes multiple different diesel engines, starting from a powerful and fuel-efficient Tier II and ending up to the state-of-the-art Stage V engine option. The Stage V engine uses passive DPF regeneration taking place during normal operation, minimizing downtime, and its modulating engine brake provides better control of vehicle speed downhill while also minimizing brake and transmission overheating and brake wear. Launching the totally renewed Toro™ LH410 is an impressive start for the 50-years jubilee of the Toro™ loaders and trucks from Sandvik. During 2021, new product launches and upgrades are expected to be released to further strengthen the Toro™ family.

Accurate Ground Investigations Saves Projects
Ground is the biggest unforeseen risk in large infrastructure projects particularly in the Philippines with tunnels, dams, transport corridors, urban development and flood protection a major part of the nationwide growth. Proven, repeatable, accurate, digitally based technologies change the game to improve understanding of ground that results in safer, sustainable, and appropriate design as well as contract price and schedule. Many Philippine infrastructure projects are hamstrung by poor quality ground investigation driven low price drilling. Contractors and owners appear deeply reluctant to allocate funds for ground investigations with engineers slow to embrace more modern proven techniques. In our view many projects essential to the Philippines’ development remain unbuilt due to large costs which are in part based on perceived contract risk or over ground engineering. The Rights Tools for the Job Modern ground investigation techniques are available in the Philippines to greatly improve project outcomes. For 15 years, RDCL staff have worked on some of the largest mining and infrastructure projects in the country. We partner with traditional contractors (drillers) and engineers to measure geotechnical parameters insitu in the ground, using techniques that do not rely on the difficulties of core sampling, and are integrated into large digital datasets in the same way as BIM systems. Downhole geophysical tools measure geological features and geotechnical parameters insitu to accurately characterise rock conditions including defect orientation, RQD measurements and rock strength. This is proven technology, which reduces the reliance on core samples and is preferred in mining and oil and gas for many years. This game changing technology should be applied regularly to the civil sector. Measurements are repeatable, high resolution and the data sets integrate with geo-modelling software world-wide. There are many occasions when drilling operations can induce stress on the samples creating drilling induced fractures. Downhole geophysical tools, like televiewers, measure in-situ rock fractures, not core fractures, and televiewers scan the entire drillhole there is no core recovery issues, there are results from top-to-bottom again reducing the unknown. As an engineer if you are trying to define fracture zones, accurately map orientation and dip from core and need reliable Rock Quality Designation (RQD) then use televiewers, it makes your job easier. There are many other tools and techniques that offer more insight and allow better understanding of geotechnical and geological conditions. Surface seismic geophysics produces fast large-scale images and datasets of the upper geological sequence across a site, and links intrusive testing together to form models with greater understanding. Test testing relying on single points (drillholes) requires inferring through unknown ground surface seismic can bridge the unknown with 2D profiles linking drill hole data. If you require to develop Sub-soil site class assessments conduct seismic shear wave velocity testing. This can work with surface equipment, such as Micro-Tremor Arrays or large seismic cabled arrays. Or if the site has a drill hole, then conduct downhole in-site seismic testing. Both are proven methods worldwide with accurate results. Cone Penetrometer Testing (CPT) for soft sediments and tailings is leading technology widely deployed in the rest of the world, and available through RDCL in the Philippines. CPT is very fast, accurate and repeatable. CPT is the most versatile in-situ soil test available. The data aids many geotechnical assessments including liquefaction, bearing capacity (foundations) and settlement. At RDCL it’s all about the people, we have the best tools and we match them with the greatest team. It’s Malasakit, family and caring. That is how we engage with clients. When you join with us you engage as a family to come out better as a result. With a focus on people, we deliver and have a successful track record of delivery in the Philippines since 1994. RDCL’s philosophy is Don’t Gamble with the Ground why risk the project when answers can be found if the right tools and the right people work together. Talk to us first, there are many ways to tackle geotechnical investigations, and the cheapest way is often not the best way. There is strong correlation between a ‘lowest cost’ approach to ground investigations resulting in project delays, inflated contract price and expensive project cost overruns. We welcome all inquiries and work best when we engage closely with you to understand your job. That’s what Malasakit means. We invite you to join with us as we take our professional journey towards bigger goals.
