Lifting the open-pit ban and using 'AI' in mining
by Patricia A. O. Bunye - August 31, 2021
In my previous column, I had mentioned that, in the Stakeholders’ Forum on Recent Policy Issuances Relating to Mining conducted by the Mines and Geosciences Bureau (MGB) last June, hopes were raised that the ban on open pit mining would finally be lifted. In response to a question in the open forum, MGB Director Wilfredo Moncano stated that the repealing clause of the draft Implementing Rules and Regulations (IRR) of Executive Order No. 130 (EO 130) would refer to Department Administrative Order 2017-10 (DAO 2017-10) on the ban on open pit mining. Thus, while EO 130 itself does not explicitly refer to the lifting of the ban on open pit mining, the intent was to lift it since, in the proposed IRR, Section 11 referred to the repeal of the said DAO.
Administrative Order No. 2021-25, or the IRR of EO 130, which was published on 08 August 2021, and which will take effect 15 days therefrom and registration with the Office of the National Administrative Register, did not repeal DAO 2017-10 or mention open pit mining at all, dashing any expectation that the ban will be lifted during this administration, notwithstanding the professed objectives of, among others: promoting direct investment for significant economic benefits of the country; ensuring adequate raw materials to support the various government projects, such as the Build, Build, Build Program and the mineral and allied industries; and promoting the development and increasing of employment opportunities in remote rural areas where there are mining activities in support to the Balik Probinsya, Bagong Pag-asa Program the government. All of these laudable objectives would be met if only the long-stalled priority open pit mining projects were allowed to proceed to operate.
On the positive side, with respect to the grant of new mineral agreements, upon effectivity of the IRR, all qualified applicants for a Mineral Agreement may now file their applications pursuant to Department Administrative Order No. 2010-21 and Republic Act No. 11032 (the Anti-Red Tape Act).
Further, the permittee of an existing Exploration Permit with an approved Declaration of Mining Project Feasibility (DMPF) may apply for a Mineral Agreement and submit to the MGB Regional Office concerned within 90 days the mandatory requirements outlined in the IRR. If complete, the MGB Central Office, 15 days from receipt of the Mineral Agreement application, shall review and shall endorse the same, to the DENR Secretary, for approval and issuance of the Mineral Agreement.
It must be noted that new Mineral Agreements shall include a stipulation that they shall adhere to the existing revenue sharing scheme and to any future legislation pertaining to revenue sharing, taxes, fees, royalties, and charges.
Previously, I also touched on how artifical intelligence (AI), which is defined as the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings, such as learning from past experience, is creeping into many aspects of how we do our work. Repetitive tasks, or those which may be done more efficiently are seen as better done by AI. The mining industry, where efficiency and productivity are paramount, has made profitable use of AI throughout the world.
In Bagdad, Arizona, for example, data scientists, metallurgists, and engineers from Freeport-McMoRan created a custom AI model at a copper-ore concentrating mill in 2018 which was loaded with three years’ worth of operating data. It was programmed to look for operational tweaks to boost output. Thirteen monitors were placed in the control room to show readings from hundreds of performance sensors located around the mill. Over time, the collected data were used to maximize copper production at a reasonable cost, with little new capital investment. The team created, tested, and refined algorithms that would look into the data and recommend settings to maximize the copper output. Their prediction model, called “TROI”, became so agile, that it was capable of issuing recommendations every 12 hours.
Though not initially reliable, “TROI” was continuously improved by the team such that its recommendations became more plausible, to the point that 80% of its recommendations were accepted by the company’s metallurgists. The mill’s production substantially increased in just four quarters with its throughput exceeding 85,000 tons of ore per day, while its copper-recovery rate rose by 10% and its operations became more stable.
In Canada, the government utilizes AI to promote clean, sustainable growth of its mining sector competitiveness by reducing costs and increasing productivity through automation. It recognizes that innovation may lead to increased efficiency and productivity, reduced costs, and improved environmental performance. The Canadian government is now using machine learning to develop better models for the prediction of rock type and economical mineral deposit locations for extraction purposes without engaging in time and resource-intensive approaches. It also uses AI to map Canada’s water and infrastructure, and to improve its ability to create geospatial data layers which can be used for emergency management, flood mapping, and change detection.
In the Philippines, despite rapid technological developments, there are currently no government issuances governing the use of AI-related technologies in the mining industry. Nevertheless, the DENR appears to recognize the impact that AI can make in preserving and protecting natural resources as it recently partnered with SMART and PLDT to protect peatlands in the Philippines using AI solutions.
Outside the mining industry, other government agencies, notably the Department of Trade and Industry considers AI as a “nation defining capability” as it created an AI Roadmap to provide an actionable guide on how to “harness AI’s potential to uplift Filipinos, our local industries, and our economy.” It is geared towards preparing the nation to maximize the benefits of employing AI technologies. The Philippines is supposedly among the first 50 countries in the world to have a national strategy and policy on AI. Such a policy is touted to increase the Philippines’ gross domestic product by 12% by 2030 as the roadmap can establish the Philippines as an “AI Center for Excellence in the region” and be a “hub for data processing” which can provide high-value data analytics and AI services to the world.
The trouble with such projections and roadmaps is that, unless they are acted upon, and until we stop shooting ourselves in the foot, they remain aspirational. We have roadmaps for practically every industry, yet we have spent decades going around in circles instead. Back in 2004, a Mineral Action Plan for the revitalization of the mining industry had already been put in place to implement Executive Order 270 (The National Policy Agenda on Revitalizing Mining in the Philippines). The DENR was to be the lead agency in crafting and implementing a strategic plan, in consultation with the other concerned agencies, such as, but not limited to, the Department of Trade and Industry, the Department of the Interior and Local Government, the Department of Finance, the National Economic Development Authority, the National Anti-Poverty Commission, the National Commission on Indigenous Peoples, the mining industry and civil society.
Despite the fantastic roadmap laid out, and three administrations later, we all sadly know what followed next: the saga of Executive Order 49 and all the other monkey wrenches thrown in, which prevented the approval of new mining agreements and projects from proceeding for many years. While this may be oversimplifying all the myriad challenges the mining industry has faced, instead of trying to find new solutions to age-old problems, it may be worth taking a second look at prescriptions that may have been there all along. Unfortunately, rare is the administration that considers and implements the plans and strategies of the previous ones, no matter how well thought out, for the simple reason that it is ‘contra-partido’ or someone else’s idea, which is why our country has not fared as well as others in the execution of long-term strategic plans.
The issuance of Administrative Order No. 2021-25 is undoubtedly a welcome development, but the road (though paved with good intentions) is still littered with obstacles, many of our own making. As we soldier on, I cannot help but wonder whether it is AI that can help humans truly learn from past experiences by warning us against committing the same mistakes and allowing us to make better decisions, or humans should finally just face up to the consequences of our folly.

What does ESG mean for the Mining Industry?
In recent years, ESG - environmental, social and governance – has become a major concern in corporate boardrooms: criteria by which strategy is developed and risks are assessed. While the term may be relatively new [having been coined as late as 2005 in a study of the International Finance Corporation (IFC) entitled “Who Cares Wins”], it has always been top of mind in the mining industry even if it has not always used the same terminology. Responsible mining companies have always been concerned about sustainability, care of the environment and working with their host communities towards achieving these goals. ESG now brings together these in a comprehensive framework that can help a mining company navigate and balance the benefits to the planet, people and profit successfully. ESG is now front and center in the discussion of many boards, even those whose businesses do not generally deal with the environment, as investors are increasingly paying attention to environmental, social and governance-related matters and data. As Forbes Magazine notes, “many investors recognize that ESG information about corporations is vital to understand corporate purpose, strategy and management quality of companies.” Increasingly, transactions are done with an eye on ESG issues. A company’s track record on ESG would certainly influence how it is able to raise funds and attract investments. In this regard, in their quest to improve diversity and broaden their representation, many boards are electing directors whose expertise and experience encompass ESG. Of course, not all boards have embraced the importance of the ESG framework in their decision-making. In a study conducted by the Harvard Business Review, they classified board attitudes towards ESG into four: “The Deniers”, “The Hardheaded”, “The Superficial”, “The Complacent” and “The True Believers”. “The Deniers” are those who see sustainability as nothing more than a buzzword or a fad, i.e., sustainability is (at most) a page in the annual report. For “The Hardheaded”, sustainability is a factor affecting their business, but reduce it to strategic reasoning (e.g. how can costs be minimized? are there market opportunities?). “The Superficial” have a shallow understanding of the need for sustainability, including those who implicitly promote greenwashing. “The Complacent” may be early adopters of initiatives like CSR reports, green product lines, or responsible supply chains, but have not kept up-to-date with the latest developments in sustainability, or use past sustainability triumphs to shut down the conversation about sustainability. Hopefully, responsible mining companies fall into the category of “The True Believers”, for whom the long-term economic viability of their organization is closely linked to, and dependent on, social and environmental responsibility. True believers undertake careful analysis of business benefits and disadvantages with a long-term approach to governance. With this backdrop, a mining company’s ESG agenda would now include, among many others: Environment: biodiversity, ecosystem services, water management, mine waste/tailings, air, noise, energy, climate change (carbon footprint, greenhouse gas), hazardous substances, mine closure Social: human rights, land use, resettlement, indigenous people, gender/diversity, labor practices, worker/community health & safety, security, small-scale miners Governance: legal & regulatory compliance, ethics, anti-bribery and corruption, transparency. [Incidentally, at his presentation at the Philippine Mining Club on November 12, Mines & Geosciences Bureau Director Wilfredo G. Moncano announced a forthcoming Department Administrative Order on enhancing biodiversity.] Many mining companies are already taking steps to assess and improve their ESG performance. Certainly, for companies in the Philippines, there is a long list of laws and regulations to be complied with that would tick all the ESG boxes. However, experts says that the real benefits come when companies move beyond mere compliance and into maximizing the opportunities arising from ESG. Mining companies also are being encouraged to improve their ESG records by aligning with internationally recognized frameworks (and seeking certification from the relevant body, if applicable): UN Guiding Principles on Business and Human Rights UN Guiding Principles Reporting Framework International Council on Mining and Metals’ 10 Sustainable Development Principles Towards Sustainable Mining (championed by the Chamber of Mines of the Philippines) Responsible Gold Mining Principles It is worth noting that in EY’s list of Top 10 Business Risks and Opportunities for mining and metals in 2022, ESG emerged as number one. More than 200 global mining executives were surveyed and named ESG, decarbonization and license to operate as the top three risks/opportunities facing their businesses over the next 12 months. With ESG at the top of the global business agenda and the intense scrutiny faced by the mining industry in particular, the challenges never cease for mining companies.

Senator De Lima passed a resolution against lifting of open-pit mining ban
Before the year ended, DENR Secretary Roy Cimatu signed the Department Administrative Order (DAO) No. 2021-40 that lifts the ban on open-pit mining. The order was passed last 23rd of December 2021. This covers mining for copper, gold, silver and other complex ores. DENR made this decision with hopes to revive the mining industry so it may once again provide job opportunities in rural areas. This decision was a response to counter the economic downturn that resulted from the global pandemic.

Vulco® R67 mill lining rubber compound is revolutionising mine site mill operations
Photo: Inside the discharge end of a ball mill being fitted with spiral lifters and rubber grates. Vulco® R67 mill liners last significantly longer and deliver a measurable reduction in mill downtime, installation and maintenance costs. Vulco® rubber is renowned throughout the mining industry for its exceptional wear life and reliability in mill lining systems. These abrasion- and impact-resistant rubber compounds have been developed with advanced technologies by the Weir Minerals’ team of expert engineers and material scientists who are continually refining Vulco® rubber products to keep them at the forefront of mill lining systems technology. Having identified a need for higher-wearing rubbers for mill lining systems, the material science experts commenced developing an industry leading, premium-grade rubber compound with superior wear life and performance in mill lining applications. The result was the Vulco® R67 rubber – an optimum material which is manufactured with proprietary new compounds and innovative methods of processing to deliver outstanding wear life and longer uptime. Extensive field research, compound testing and site trials were conducted to ensure that it was not only able to withstand severe abrasion in typical mill system applications, but that it is best in class. In fact, it has been the most wear-resistant rubber compound that Weir Minerals has ever developed for mill lining applications. The R67 compound boasts a high hardness, elongation, tensile and tear strength, and is suitable for lifter bars, head/shell plates and grates. When it’s utilised in conjunction with metal cap mill liners, the result is a versatile, economical and efficient product that weighs up to 50% less than steel alone. The added benefit is a lighter product that’s faster, easier and safer to install. Revolutionising wear lining Since its launch in 2018, many mining operators from around the globe have implemented the R67 compound into their mill lining systems. They have reported as much as 20-40% improvement in wear life, which is resulting in fewer mill lining replacements and longer mill campaigns. This reduction in shutdowns has a dual benefit of increased cost savings and improved plant availability. What are the benefits for the mill operators? With a liner that can run significantly longer, operators have experienced a wide range of benefits including: Improved wear life A measurable reduction in mill downtime Increased uptime and processing Easier and safer installations Reduced maintenance costs In addition to this, the mines benefit from having an experienced and dedicated team from Weir Minerals who custom-engineer the liners to suit each mill’s unique requirements for optimal wear life. Global in-field success The R67 elastomer compound is changing the way mills operate - with exceptional results. Extensive global trials and commercial installations in the market have resulted in a number of successful outcomes across a variety of different grinding applications. From mines in the USA to Chile, the R67 has proven its outstanding performance consistently. As an example, a high-grade nickel and copper mining project in the USA had a problem where the liners in one ball mill were wearing out too quickly, leading to continued downtime and reduced processing. They were looking for a product significantly superior to the elastomer that they were using. Initially there was reluctance from the mine, as they had loyalty to their original mill supplier, however after Weir Minerals conducted a series of trajectory simulations and discreet modelling - to optimise the design and deliver the best process performance for the mill, they agreed to trial the R67 liners. At the end of the trial the R67 showed 30-40% better performance than the incumbent liners and the customer installed a full set of R67 liners in their mill. Another trial in the USA took place in an iron ore mine with several dozen ball mills in operation. Here, Vulco® R67 liners delivered a 17% increase in life compared to the failed shell plates from the mine’s original mill lining system supplier. The company was extremely impressed with the results and installed a complete shell liner in their ball mill. Moving to Chile, a copper mine was keen to trial the R67 compound to see if they could improve the wear time of a competitor rubber liner. After a three-month trial, all liners were physically measured showing that the Vulco® R67 liners fully worn wear life projected from the actual wear would be 80% longer compared to the incumbent liners. Another copper processing plant in Chile trialled R67 composite liners in their SAG mill against two other compounds that are commonly used in the industry. After 12 months, there was a 48% and 62% wear life improvement on the other liners – proving that the R67 composite liners could withstand the highly abrasive environment. Helping customers optimise their process As leaders in material technology, Weir Minerals are continuously undertaking research and development to provide best-in-class products to mining customers, while helping them improve their bottom line. When using Vulco® R67 rubber compounds, our customers can feel assured they have a market-leading product that is backed by decades of experience, expertise, and proven effectiveness. This innovative rubber compound not only delivers superior physical and viscoelastic properties but is also a lighter and safer material to use. Where can you find Vulco® R67? Vulco R67® mill liners are made exclusively at Weir Minerals facilities in North and South America, Australia and South Africa, with plans to expand production into more regions in the future.
