Using dewatering systems to improve site efficiency
Photo: Multiflo® mega barges on site in Brazil Dewatering is critical to a mine’s operations and more resources are being allocated to its optimisation. Traditionally, there’s been a tendency among some mine and quarry operations to view dewatering as something to be avoided at all costs – until it can’t be. Therefore, cost minimisation has been the primary focus when it comes to implementing a dewatering or fluid management solution. However, with dewatering becoming increasingly necessary, operators are approaching these challenges in more sophisticated and methodical ways. The trends informing dewatering practices mirror many of those that are observable across all mining processes: a focus on sustainability and the efficient use of energy and other resources; customised, holistic solutions based on each sites unique geological and climatic conditions; and the emergence of new technologies, with a particular focus on real-time monitoring. Dewatering solutions that are carefully designed and implemented have the potential to reduce energy usage, CO2 emissions and significantly lower OPEX over the life of the mine. The overall efficiency is affected by individual elements, but also by how these elements interact and operate with one another. The renewed focus on pumping efficiency requires a significant shift in how many operators have previously approached dewatering and fluid management on site. Because most dewatering programs have been designed with the singular focus of lowering groundwater levels as quickly as possible, they often have excess pumping capacity and oversized pipes and pumps operating at only a fraction of their capacity – a process that’s inherently inefficient. This needs to change to accommodate the increased focus on efficient use of energy and water, which is critical to maintaining a social licence to operate. Multiflo® MF pump unit on site in Indonesia Improving pump efficiency begins with effective monitoring. There have been enormous improvements in electronic control and communication systems in the last few decades. Real time reporting and control of pumping systems can now be an economic reality for almost any mine site. The more visibility you have over your fluid management on site – flow rates, operating pressures, groundwater level, water quality, system relocations, alternate drive solutions, equipment selections to reduce maintenance and repair cycles, etc. – the better placed you will be to install the most appropriate equipment. The industry is moving towards customised solutions and there’s a growing awareness that no two sites are the same, which means a one-size-fits-all approach to dewatering is neither cost effective nor sustainable. Weir Minerals has a global team of dewatering experts who partner with mine operators to assess their specific requirements and provide integrated solutions. With a long and proud history of innovative engineering, Weir Minerals has a team of process and design engineers armed with the latest technology, specific process knowledge and site experience to optimise your dewatering management processes. We take advantage of our global capabilities and engineering skills to provide our customers with the best solution as quickly as possible. With an extensive global network and the ability to service on-site or at one of our 130 dedicated service centres, we are always there when you need us - no matter how remote your operation is.

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.

NICKEL ASIA CORPORATION ANNOUNCES P3.83B NET INCOME FOR H1 2022, UP 41% YoY
Photo Credit: Arrow Creatives Nickel Asia Corporation, the Philippines’ largest producer of lateritic nickel ore, reported a 41-percent increase in attributable net income for the first semester this year. Based on unaudited financial and operating results for the six-month period ended June 30, 2022, attributable net income increased to P3.83 billion from P2.73 billion while earnings before interest, tax, depreciation, and amortization (EBITDA) increased by 19 percent to P6.33 billion from P5.32 billion the year prior. Despite lower ore volume sold during the period, revenues increased by 7 percent to P11.78 billion from P11.01 billion last year, owed largely to higher nickel ore prices and favorable exchange rates. NAC’s four operating mines sold a combined 6.95 million wet metric tons (WMT) of nickel ore during the first half of the year, down 16 percent from 8.30 million WMT in the same period last year. The drop in sales volume was almost in direct proportion to unrealized workable days caused by inclement weather that adversely affected the Company’s mining operations during the period. The weighted average nickel ore sales price over the first half of year 2022 rose by 18 percent to $30.03 per WMT against $25.54 per WMT in the same period last year. The Company also realized P52.56 per US dollar from these nickel ore sales, a 9-percent increase from P48.25 last year. Breaking down the ore sales, the Company exported 3.12 million WMT of saprolite and limonite ore at the average price of $42.05 per WMT during the six-month period compared to 4.55 million WMT at $37.62 per WMT in the same period last year. Likewise, the Company delivered 3.83 million WMT of limonite ore to the Coral Bay and Taganito high-pressure acid leach (HPAL) plants, the prices of which are linked to the London Metal Exchange (LME) and realized an average price of $12.52 per pound of payable nickel. This compares to 3.74 million WMT at $7.92 per pound of payable nickel in 2021. Expressed in US dollar per WMT, the average price for the deliveries to the HPAL plants were $20.23 and $10.85 in the first half of 2022 and 2021, respectively. “The first half of 2022 was not without its challenges especially for our mining operations, brought about by weather conditions at our mine sites, particularly in Surigao, and continuing lockdowns in China, our major market,” said Martin Antonio G. Zamora, President and CEO. "However, the higher LME nickel price and stronger US dollar tempered the impact on our revenues.” Owing to the higher LME nickel price during the period, NAC also recognized gains from its equity share in investments in the two HPAL plants in the combined amount of P1.09 billion against P244.1 million year-on-year. The stronger US dollar further enabled NAC to log a 353-percent hike in net foreign exchange gains from its foreign currency-denominated net financial assets to P863.5 million from P190.6 million the year prior. Total operating cash costs decreased by 2 percent year-on-year to P5.19 billion from P5.32 billion last year. On a per-WMT sold basis, total operating cash costs increased to P747 per WMT compared to P641 per WMT in 2021. For the Company’s renewable energy business, its subsidiary, Emerging Power, Inc. (EPI) energized in June 2022 another 38-megawatt (MW) solar farm in Subic, Zambales, bringing total capacity on this site to 100MW. For 2022, the Subic plant has been operating at an 18- 19% plant efficiency factor with 90% of generation contracted under power sales agreements. EPI has realized an average tariff of P4.65 per kilowatt hour. EPI has another 100MW service contract for the Subic site and will commence construction of a 68-MW farm in August. Completion is expected by the third quarter of next year. EPI was also chosen by Shell Overseas Investments B.V. to be its exclusive local partner in a solar, onshore wind, and battery storage joint venture that aims to contribute up to 3GW into the Philippines’ renewable capacity. NAC is evaluating a range of financing alternatives including accessing global debt capital markets to raise EPI’s share of the equity required for an initial 1GW target by 2028, among other uses. The Company’s strong financial position will allow it to be opportunistic in evaluating funding options that meet the primary objective of maintaining a flexible low-cost capital structure. “We remain confident that our mining and renewable energy businesses provide a solid foundation on which to realize the OneNAC Vision’s twin objectives, which is to become the premier ESG investment in the country and to be counted among the Top 25 PSE-listed companies in terms of market capitalization by 2025,” said Zamora.

Further shallow copper mineralisation identified at MCB
Figure 3. Cross section of drill hole MCB-039 relative to the interpreted geology and significant assay results. We (Celsius Resources) are pleased to announce we have received further shallow and high-grade copper assay results from the ongoing drilling program at our flagship MCB copper-gold project, held under our Philippine subsidiary Makilala Mining Company, Inc. (“MMCI”). The results continue to identify new positions of shallow mineralisation which are in line with other recent drilling results from holes MCB-036, MCB-037 and MCB-038 (see CLA announcements dated 13 December 2021, 23 May 2022 and 4 July 2022 respectively) confirming the presence of an extensive shallow higher-grade position. The results from MCB-039 were designed to further expand the size of the shallow higher-grade copper zones which are considered to have an important positive impact on early mining options at MCB. The current drill hole in progress (MCB-040) is similarly designed to further expand the higher-grade copper mineralisation leading to potential improvements to the economics of the already positive Scoping Study at MCB as reported by Celsius on 1 December 2021. “The results from MCB are continuing to grow the size of the shallow higher-grade copper zones,” said Country Operations Director, Peter Hume. “We are getting much better definition now on the various high-grade zones, which are important for the optimisation of the MCB mine plan. We can see many good high-grade intersections coming together to expand on the earlier understanding of these high-grade zones. Where we get multiple high-grade zones staked on top of each other, we can achieve outstanding results, as recently announced from hole MCB-038 which intersected 611.4m @ 1.39% copper and 0.75g/t gold from 32.5m.” RESULTS FROM MCB-039 Drill hole MCB-039 was drilled to further confirm the interpretation that further shallow high-grade positions exist as a relatively flat body extending into the surrounding host rocks (see Figures 2 and 3). This drill hole was more specifically targeted to fill a gap in the drilling information where there was previously defined lower grade copper mineralisation. The results from MCB-039 have confirmed the further extensions to the higher-grade copper mineralisation as part of a series of relatively flat lying, high-grade zones which are extending away from vertically orientated feeder structures which are all closely related to an intrusive Tonalite rock (Figure 3). Figure 2. Location of MCB-039 drill hole relative to recent and historical diamond drilling at MCB. A large broader envelope of copper mineralisation at a lower cut-off grade at approximately 0.2% copper also continues to be better defined, highlighting the very large scale of the copper-gold mineralisation at the MCB deposit.

Diokno banks on mining for sustained economic recovery, expansion
Photo credit: PNA - Finance Secretary Benjamin Diokno Finance Secretary Benjamin Diokno said the mining industry is a potential source of sustained economic growth as he underscored the benefit of mobilizing investments for mine development. “The mining industry holds the greatest potential to be a key driver in our economic recovery and long-term growth, especially now that world metal prices are high. The Philippines, after all, is one of the world’s most richly endowed countries in terms of mineral resources,” he said Wednesday at the listing of Philex Mining Corporation’s (Philex) common shares in the Philippine Stock Exchange (PSE). Philex is mobilizing investments for the development of its Silangan underground copper-gold mine in Surigao del Norte. In a disclosure to the PSE, the company said it is offering a maximum of 842 million common shares at the rate of one offer share for every 5.8674 shares owned for PHP3.15 each to raise a total of PHP2.652 billion new equity. The stocks rights offering (SRO) period started on July 12, 2022 and ended July 25, 2022. The Silangan project, considered one of the biggest copper-gold mines in the country, is planned to be mined in two phases. The first phase has a mineable ore reserve of 81 million metric tonnes which will be mined for 22 years at a rate of 4 million tonnes per year. The mine is targeted to commence commercial operations in the first quarter of 2025. Diokno said Philex’ SRO listing demonstrates the mining industry’s confidence in the country’s promising economic growth prospects. He said the offering means more jobs will be created, local economies will be reinvigorated, and additional revenues will be contributed to the government. The Department of Finance (DOF) estimates that the project will generate around PHP8.5 billion in excise taxes alone for its entire mine life. Diokno said the listing sends a strong signal to the mining industry that the country's capital markets are viable instruments for fast tracking the development of large mining projects. He said the Marcos administration is committed to continue creating an enabling environment for mining activities to flourish in the country as he looks forward to similar listings in the future. “We recognize that apart from boosting local development, mining is a strong magnet for investments that can propel our economy into a higher growth trajectory,” he added. Diokno said the government expects the mining industry to strictly adhere to responsible and sustainable mining practices. He said the mining industry should strike a balance between protecting the environment, uplifting local communities, and supporting the government’s socioeconomic agenda. “This is a non-negotiable condition so we can guarantee the sustainability of the industry and the strong economic growth of its host communities,” he said.
