Philex Mining Corporation is pleased to announce the completion of the In-Phase Mine Plan feasibility study and an updated mineable reserve estimate for the Boyongan deposit in accordance with the 2012 Philippine Mineral Reporting Code (“PMRC”).

A feasibility study for a 4 Million tonnes per year sub-level cave mining plan for the Boyongan copper porphyry deposit was previously completed and disclosed in 2019 and was used as the basis for the In-Phase Mine Plan feasibility study. The in-phase plan consists of a starter sub-level cave mine that has an annual ore production of 700 thousand tonnes or 2,000 tonnes per day. Mining will commence at the East sub-level cave because it has the highest grade ore. A new decline will be developed to access the East sub-level cave while the existing exploration decline will be rehabilitated to serve as an alternative mine access and a ventilation exhaust for mine air. Ore coming from the starter mine will be hauled using mine trucks from the underground to the process plant at the surface, where it will be crushed and ground to required sizes.

Copper, gold and silver will be recovered using copper leaching and gold leaching processes because the ore at this point consists of predominantly oxide minerals. The processing plant will produce a London Metal Exchange (LME) grade (99.999%) copper cathode and gold-silver dore. Tailings from the processing plant will be piped to the Tailings Storage Facility which is 5 Kilometers to the northwest of the Boyongan ore body. The initial capital cost to develop the starter mine is estimated to be US$ 224 Million, which will be spent within the 2.5 years development period.

The 2,000 tonnes per day starter mine will last for 5 years, after which on the sixth year of production, mining and processing rate will increase to 4,000 tonnes per day or 1.3 Million tonnes per year. By the ninth year, ore production and processing rates will again increase to 8,000 tonnes per day or 2.7 Million tonnes per year. On this year as well, a copper flotation circuit will be added to the process plant as the ore mined now consists of oxide and sulfide minerals. Copper flotation will produce copper concentrates with gold and silver. The final ramp up will occur on the twelfth year. Ore production rate starting this year up to when the mineable ore will be exhausted will be 12,000 tonnes per day or 4 Million tonnes per year. The life of mine for Phase 1 Boyongan is 28 years.

The resulting updated mineable reserve estimate below is the culmination of the In-PhaseMine Plan feasibility study undertaken. After incorporating standard mining factors to the mineral resource, the competent person for this report has delineated 81 Million tonnes as mineable reserve.

Philex Delivers PHP1.149B Core Net Income in 1H2021, An Increase of 186% Compared with 1H2020

Photo Credit: Redjie Melvic Cawis Philex Mining Corporation announced that the Company achieved another new high in its revenues and core net income for 2Q2021. Philex recorded a Core Net Income of Php610 million for the 2nd quarter. In addition to the Php540 million core net income it already recorded in 1Q2021, Philex registered a new high core net income for the first half of the year at Php1.149 billion. Satisfactory execution of the mining plan resulted in sustained level of metal output, and optimum operating cost and expenses delivered the higher core net income for the quarter and year-todate ended June 30, 2021. The Company reported a Net Income of Php600 million for 2Q2021 versus the reported Net Income of Php322 million for the same period in 2020, an 86% increase. Production and Revenues The Company milled slightly lower tonnage than the first quarter of 2021 resulting in slightly lower copper output for 2Q2021. Despite the slightly lower copper output, the Company generated higher revenues for 2Q2021 at Php2.377 billion, higher by 21% over the same period in 2020. This brings 1H2021 revenues to Php4.747 billion, ahead by 29% over the same period in 2020, with revenues only at Php3.680 billion. The higher revenues are due mainly to the sustained higher realized metal prices for both Gold and Copper at $1,807 per ounce and $4.21 per pound, respectively. The satisfactory execution of the mining plan and mill operations resulted in the production of 13,612 ounces of Gold and 6.435 million pounds of Copper for 2Q2021, bringing the 1H2021 total metal output at 27,025 ounces of Gold and 13.205 million pounds of Copper. Operating Costs and Expenses Core and Net Income Operating costs and expenses for 2Q2021 at Php1.593 billion are higher than those of 2Q2020 at Php1.552 billion due to slightly higher production expenses and higher excise taxes and royalties attributable to higher revenues. The slight increase was tempered by lower non-cash production costs in 2Q2021 amounting to Php271 million compared with non-cash production costs in 2Q2020 amounting to Php330 million. This brings the 1H2021 operating costs and expenses to P3.240 billion, higher by Php136 million compared with 1H2020. The increase is attributable to increasing production cost brought about by the effects of the pandemic to the supply chain, including logistics and Covid-19 response undertaken by the Company. Reported Net Income for 2Q2021 increased by 86% to Php600 million from Php322 million in 2Q2020 This brings the Company’s 1H2021 reported Net Income to Php1.159 billion from Php425 million of 1H2020. Core Net Income for 2Q2021 reached Php610 million to close the 1H2021 Core Net Income at Php1.149 billion, higher by 186% versus the Core Net Income of Php402 million in 1H2020. The Company generated EBITDA of Php1.016 billion for the 2Q2021 versus Php708 million in 2Q2020, a 44% increase. This brings the 1H2021 EBITDA to Php2.027 billion versus Php1.127 billion in 1H2020, an increase of 80% COVID 2019 Despite our strict implementation of the IATF-DOH mandated health protocols, the Company was not spared by the spread of the Covid19 virus. Several employees and their dependents were infected by the virus but the infection was immediately contained, preventing widespread transmission, and ensuring the continued operation of both the mine and mill plant. The Company adopted and implemented regular surveillance and contact tracing activities to further strengthen its defense against any transmission to its employees and their dependents. Silangan Project The Board of Directors of Philex has approved the In-Phase development of Silangan and the Company will be appointing a financial advisor to assist in the fund raising that will commence as soon as practicable. With the In-Phase development of Silangan, the capital expenditure requirement will be made in stages, and can be funded from a variety of potential resources including internally-generated cash and potentially through equity and debt from investors and creditors. The Company is confident that Silangan development will start by Q22022 with the target of commencing commercial operations in January 2025. “We will be working with our financial advisor to immediately implement the fund raising activity for the InPhase development of Silangan. We believe that the recent government pronouncements related to the mining industry will increase the level of interest and confidence of investors and lenders to mining companies. The launch of Silangan will be very timely.”, emphasized Eulalio B Austin, Jr, Philex President and CEO. “The global outlook for metal prices continue to be positive and Philex is poised to benefit as we emphasize on excellent execution of plans in light of the current volatile environment brought about by this pandemic. In the next couple of months, we set to launch our Silangan Project under an In-Phase Development approach. Silangan will be an exciting project for Philex.”, concluded Manuel V. Pangilinan, Philex Chairman.   Article Courtesy of The Philippine Stock Exchange

Philex core net income jumps 116% to Php1.865 billion in three quarters

Despite the challenges posed by the Covid-19 pandemic, production and favorable metal prices for gold and copper have been sustained since 1Q2021. As a result, the Management and the Board of Directors of Philex Mining Corporation recently announced that the Company generated another quarter of positive results. Philex recorded a Core Net Income of Php716 million for the quarter, higher by 55% than the same period in 3Q2020, mainly due to higher copper prices, favorable foreign exchange rates and managed operating expenses. The 3Q2021 Core Net Income of Php716 million rides on the positive and upward profit trend from the Php540 million achieved in 1Q2021 and the Php610 million posted in 2Q2021. This brings the 9M2021 core net income to Php1.865 billion, higher by 116% over the same period of 9M2020, attributable to favorable metal prices, sustained metal output and efficient deployment of operating costs and expenses. On the other hand, 3Q2021 EBITDA at Php1.168 billion continue to maintain the positive trend during the first two quarters EBITDA of Php2.027 billion, to top up 9M2021 EBITDA to Php3.194 billion, a 57% rise from the same period 9M2020. Reported net income for 3Q2021 is Php721 million, a 46% increase over the same period 3Q2020, while 9M2021 Reported net income reached Php1.880 billion, a 105% increase from 9M2020. Production and Revenues The Company generated higher tonnage in the third quarter of the year. For 3Q2021, total tonnage milled was at 2.006 million tonnes slightly higher compared to 1.985 million tonnes in 3Q2020 and 1.943 million tonnes of 2Q2021. Philex produced slightly lower gold output at 14,270 ounces in 3Q2021 when compared to 3Q2020 due to lower gold grades while the slightly higher copper grades produced higher copper output at 6.54 million pounds, which mitigated the impact to the total revenues. The Company was able to maintain a positive trend in metal output since 1Q2021 for both gold and copper mainly due to the resilient execution of the mining plan that resulted to better blended metal grades and sustained level of metal output. The favorable prices for both gold and copper attributed to the higher revenues for 3Q2021 at Php2.656 billion, a 13% increase over the revenues of the same period of 3Q2020 at Php2.350 billion. The favorable foreign exchange rate contributed to higher revenues in 3Q2021. For the 9M2021 period, revenues at Php7.742 billion was higher by 22% from revenues of 9M2020 at Php6.332 billion. This is attributable to the significant increase in the realized price of copper since 3Q2020 resulting into a higher contribution of revenues from copper at 52% of total revenues for 9M2021 from 40% of total revenues for 9M2020. On the other hand, revenues contribution from gold declined from 59% in 9M2020 to 47% in 9M2021 mainly due to the slightly lower gold output, from 43,136 ounces in 9M2020 to 41,295 ounces in 9M2021. Operating Costs and Expenses The Company’s operating cost and expenses for 3Q2021 stood at Php1.603 billion, higher than 3Q2020 of Php1.582 billion. The slight increase is consistent with the slightly higher tonnage milled in 3Q2021 versus 3Q2020. Materials and supplies usage at Php454 million accounting for 28% of operating cost remained almost the same level. Power costs, accounting for 18% of operating cost, was higher at Php290 million, an of 7% when compared to 3Q2020. Overall, the Company continue to manage operating cost efficiently. For the 9M2021, operating cost inched up by 3% to Php4.843 billion from Php4.686 billion in 9M2020 as a result of higher power and labor costs from higher tonnage milled, and higher excise taxes attributed to the higher total revenues. For the nine months period ended September 30,2021, the Company recorded its share in the net losses of its associates amounting to Php510 million, inclusive of the Company’s share in the PXP Energy Corporation provision for impairment of assets and goodwill related to Peru block Z-38, net of proceeds from the settlement agreement with third party. As a result of the extension of the Padcal mine life from December 31,2022 to December 31,2024, the Company recognized a net reversal of the previously recorded impairment provision in its mining assets amounting to Php374 million. Positive outlook and extension of Padcal life of mine By itself, 3Q2021 ushered in a more stable and continuing positive outlook for the mining industry, brought about by significant developments in the previous quarter. In April 14, President Rodrigo Roa Duterte issued Executive Order No. 130 which amended Section 4 of Executive Order No. 79 and lifted the moratorium on mineral agreements that had been existing for the past 9 years. This will pave the way for the development of stalled mining projects, leading to renewed investor’s interest in our Silangan Project. The Company is currently exploring options on viable financial packages that would bankroll a phased development approach (In Phase Development) of Silangan. The extended Life of Mine from December, 2022 to December, 2024 will ensure the continuous employment of 1,831 Padcal employees and support the social development of the Host Local Government Units (LGU) and neighboring communities especially in this time of COVID- 19 Pandemic. It will also give more time for the Company to bring the Silangan Project to development and commissioning stages. “In response to this global trend of strong demand and strong metal prices, as well as responding to the Government challenge for the revitalization of the mining industry, Philex will keep improving on how we do things and undertake innovative initiatives related to the promotion of right and principled mining,” according to Eulalio B. Austin Jr., President and CEO. “The pursuit for excellence is a continuous journey and we have to keep raising the bar.” “With higher metal prices and a better economic outlook for the mining industry moving forward, we can maintain the momentum of last year’s exemplary performance into this year, notwithstanding the pandemic and the challenges we have faced in our operations,” concluded M.V. Pangilinan, Chairman. “Time and again, the women and men of Philex have proven their resilience during tough times. With the extension of Padcal mine life for another two years, the prospect of a viable financial package for our Silangan project, and the rollout of our vaccination program for our employees and their dependents, it looks like the full year 2021 will produce excellent results for your Company.”   Article courtesy of the Philippine Stock Exchange

Philex Mining Extend Padcal Mine Life to 2024

Philex Mining Corporation, one of the oldest and largest gold and copper producers in Southeast Asia, has, after the completion of confirmatory drilling and related technical studies on the mining methodology and Tailings Storage Facility (TSF) No. 3, successfully identified from the end of 2022 additional mineable reserves in its Padcal Mine that are feasible for mining. The updated remaining mineable reserves as of end March 2021 are estimated at 30.2 Million tonnes with average gold and copper grades of 0.23 grams per tonne (g/t) and 0.18%, respectively. This new estimate includes additional reserves of 16.2 Million tonnes from the previously declared estimated mineable reserves as at end 2020 of 17.4 Million tonnes with an average gold and copper grades of 0.27 g/t and 0.18% that was reported in February 2021. The additional mineable reserves are expected to be mined over two years, extending the life of Padcal Mine until December 31, 2024. The latest mineable reserves estimate was undertaken by Engineer Ricardo S. Dolipas II, an accredited Competent Person by the Philippine Society of Mining Engineers (PSEM) under the Philippine Mineral Reporting Code (PMRC) Guidelines.  More importantly, the extended Life of Mine will ensure the continuous employment of 1,831 Padcal employees and support the social development of the Host Local Government Units (LGU) and neighboring communities especially in this time of COVID 19 Pandemic. It will also give more time for the Company to bring the Silangan Project to development and commissioning stages. The Company is currently processing all required permits and other regulatory requirements in connection with this impending Life of Mine extension.

Sampulna cites need for more mineral processing plants to boost PH production

Photo credit: DENR - Mr. Jim O. Sampulna Former Department of Environment and Natural Resources (DENR) Acting Secretary Jim O. Sampulna pushed for the establishment of more mineral processing plants and utilization of rare earth deposits to help increase the country’s mineral production and revenue generation. “Mineral processing plants make the mined mineral ready to use for application. For example, limestone, if processed, will become cement, which is ready to use for construction,” Sampulna cited. “If we have more of these plants and more minerals will be processed in the country, then its value will increase even more than 100 percent, and lesser raw materials will be shipped out to other countries, like Japan or China,” he said. The DENR-Mines and Geosciences Bureau has so far issued 108 mineral processing permits, most of which are for construction materials. Likewise, Sampulna proposed the identification of rare earth elements (REEs), such as scandium and yttrium, in operating mines. Sampulna, who was the former DENR undersecretary for mining, said that these metals are essential parts for many high-technology devices. “The Philippines is conducive to these minerals. It could contribute to the national government through the identification and utilization of these commodities. To date, there are only a few operating mines which have identified REEs,” he said. Sampulna cited that a proposed iron mineral processing plant in Zamboanga had its groundbreaking ceremony on June 18, to support the DENR’s initiatives toward self-utilization of mineral commodities in the country. “We hope that investors will push for the opening of more processing plants in the Philippines,” he said. He also assured Filipinos that the DENR will continue to strengthen its regulation and monitoring of mining operations to ensure sustainable and responsible mineral production in the country.   Article courtesy of Department of Environment and Natural Resources

DENR Awards MGB with Plaque of Appreciation for the Success of the Boracay Island Rehabilitation

Photo: The MGB Boracay Island Rehabilitation Team together with former DENR Secretary Roy A. Cimatu Four years after the Department of Environment and Natural Resources (DENR) spearheaded the rehabilitation of the Boracay Island, the DENR Acting Secretary and Boracay Inter-Agency Task Force (BIATF) Chair Jim O. Sampulna CESO I awarded the Mines and Geosciences Bureau (MGB) a Plaque of Appreciation for its valuable contribution to the success of the Boracay Island Rehabilitation during the BIATF’s culminating event on June 16, 2022. Boracay Island is one of the most developed and densely populated karstic islands in the Philippines. The extensive alteration of its natural landscape, as well as the alleged discharge of wastewater into the sea, posed a major environmental concern, prompting its temporary closure on April 26, 2018. The BIATF then launched the rehabilitation of Boracay island to safeguard its sustainable development. As part of the BIATF, the MGB team, led by Lands Geological Survey Division (LGSD) Chief Liza Socorro J. Manzano, was composed of technical personnel from the LGSD of MGB Central Office and the Geosciences Division of MGB Regional Office No. VI. The team conducted studies on hydrogeology, coastal geohazards, karst subsidence hazard, and geophysical investigations using Ground Penetrating Radar (GPR) and georesistivity.   The highly specialized studies sought to provide a holistic understanding of the island’s karstology and the impacts of tourism development to ensure that the rehabilitation efforts of the government are predicated on the ecological sustainability of the small island karst. Ultimately, the results of the GPR investigation on pipes discreetly disposing wastewater and polluting the seawater of Boracay which resulted in the discovery of their existence and eventual dismantling of the same is a "game-changer" relative to the implementation of science-based strategies and crafting of policies for appropriate wastewater and solid waste management in the island.    Article courtesy of the MGB

The Fault with Cobalt: Overcoming the Challenges of Battery Metal Exploration

 upply Co., Inc. Cobalt is an important element used to manufacture rechargeable batteries. Cobalt has unique properties that help improve thermal stability, which is critical for the batteries to function properly. It also helps improve some batteries’ energy density, so they can last longer. The demand for cobalt is high, so geologists need fast, accurate tools to help them meet these requirements. Portable X-ray fluorescence (pXRF) analyzers are one of these tools, as they provide on-the-spot material chemistry results. Why Choose Portable XRF for Cobalt Exploration? Portable XRF provides rapid, in situ, multielement geochemistry for immediate results in the field. This is useful for greenfield and brownfield exploration, ore grade and process control, environmental monitoring and remediation, and researching/teaching within the geological/environmental sciences. For battery metal exploration, portable XRF provides decision-quality data faster than traditional, lab-based XRF, and also enables more discriminatory laboratory sampling, helping reduce costs and improve ROI. With sample preparation, pXRF produces high-quality quantitative data that is comparable to laboratory analysis. Challenges with Analyzing Cobalt XRF is prone to inter-element interferences. Iron (Fe) on cobalt (Co) and nickel (Ni) on cobalt (Co) are two common examples. This means that when a lot of iron is present, it becomes difficult for XRF to identify cobalt at low levels. Likewise, the presence of nickel also makes it difficult for XRF to ID cobalt. Unfortunately, cobalt is routinely explored for in the presence of significant amounts of iron and nickel. To solve this challenge, we developed a GeoChem method for Vanta™ pXRF analyzers that offers improved analysis for battery metals exploration by being able to detect cobalt in the presence of iron and nickel. This innovative method overcomes the interference that has historically made it very difficult for portable XRF analyzers to detect cobalt in the presence of these other elements. The method we developed for the Vanta analyzer is built on the current GeoChem method, but with a more sophisticated way of deconvoluting the iron/cobalt/nickel peaks. Before deploying this solution, we tested it on client samples to make sure that it produced good results. Test Results We analyzed 16 samples with high iron content—9% < Fe < 50%, 50 ≤ Co ≤ 6000 ppm, Ni < 500 ppm. We also analyzed 50 samples with a moderate amount of iron—0.5% < Fe < 15%, 16 < Ni < 8000 ppm, 50 ppm < Co < 2.3%. The samples were pulps in XRF cups, and they were analyzed using 60 seconds per beam with no corrections. The graphs below show excellent agreement between the results obtained from a lab and results obtained using a Vanta portable XRF analyzer, indicating that the modified GeoChem method can accurately detect the presence of cobalt when it’s in the presence of both large and moderate amounts of the interfering elements iron and nickel. Geologists now have another important tool that they can rely on when exploring for new sources of this vital element.
