The Supreme Court upheld the validity of production limits for small-scale mining operations. The Court ruled that the Department of Environment and Natural Resources (DENR) has the authority to impose an annual production limit of 50,000 metric tons on small-scale mining, regardless of whether the operation is governed by Presidential Decree (PD) No. 1899 or Republic Act (RA) No. 7076. This decision reinforces the DENR’s role in protecting the environment and ensuring sustainable use of the country’s mineral resources by preventing over-extraction and irreversible environmental degradation. The ruling provides a uniform standard for regulating small-scale mining, addressing concerns about unequal treatment and clarifying the definition of ‘ore’ for extraction measurement purposes.

Ore Wars: Can Small-Scale Miners Exceed Extraction Limits?

This case revolves around the operations of SR Metals, Inc., SAN R Mining and Construction Corp., and Galeo Equipment and Mining Co., Inc., collectively referred to as the ‘mining corporations.’ They were granted Small-Scale Mining Permits (SSMPs) to extract Nickel and Cobalt (Ni-Co) in Agusan del Norte. The permits were subject to a condition that annual extraction should not exceed 50,000 metric tons (MT), based on Section 1 of PD 1899:

Section 1. Small-scale mining refers to any single unit mining operation having an annual production of not more than 50,000 metric tons of ore x x x.

A dispute arose when the Agusan del Norte Governor questioned whether the mining corporations had exceeded this limit. The mining corporations argued that only the actual Ni-Co extracted, excluding the gangue (unwanted rocks and minerals), should be considered as ‘ore.’ The Department of Environment and Natural Resources (DENR), however, contended that the 50,000-MT limit applied to the total mass extracted from the mine, including soil and other materials, before any separation or processing. This led to a Cease and Desist Order (CDO) issued by the DENR against the mining corporations for allegedly exceeding the extraction limit.

The mining corporations then sought relief from the Court of Appeals (CA), arguing that the DENR had abused its discretion. They contended that PD 1899 had been impliedly repealed by RA 7076, which does not specify an annual production limit for small-scale mining. They also claimed that the equal protection clause was violated because RA 7076 miners faced no such limit. The CA sided with the DENR, upholding the validity of the 50,000-MT limit and the DENR’s interpretation of ‘ore’ to include the total mass extracted. The mining corporations elevated the case to the Supreme Court, raising the same constitutional and interpretative issues.

The Supreme Court addressed two key issues: the constitutionality of the 50,000-MT production limit in PD 1899 and the correct interpretation of this limit. The mining corporations argued that the absence of a production limit in RA 7076 created an unequal classification between miners under the two laws, violating the equal protection clause. They also maintained that the term ‘ore’ should be confined to the economically valuable Ni-Co, excluding the gangue. The Court rejected both arguments, emphasizing the DENR’s authority to regulate the country’s natural resources. The Court emphasized that Executive Order 192 provides the DENR with the mandate to manage and conserve the country’s environment and natural resources, and to promulgate rules and regulations regarding the exploration, development, and use of these resources.

The Court noted that while PD 1899 and RA 7076 have different scopes—PD 1899 applying to individuals, partnerships, and corporations, while RA 7076 applies to cooperatives—both laws delegate to the DENR the power to issue implementing rules and regulations (IRRs). Significantly, the DENR, in the exercise of such power, issued DMC 2007-07, which imposed the 50,000 DMT annual production limit for both SSMPs issued under PD 1899 and Small-Scale Mining Contracts (SSMCs) under RA 7076. By imposing the 50,000 MT limit across the board, the DENR harmonized the two laws and eliminated any potential equal protection concerns. Therefore, the Court stated that any claims regarding the violation of the equal protection clause are now moot.

The Court also addressed the interpretation of the 50,000-MT limit. The mining corporations had asserted that the limit should only apply to the Ni-Co component, excluding the gangue. The Court disagreed, citing Mines Administrative Order (MAO) No. MRD-41, which specifies measuring the ‘run-of-mine ore.’ This means that the ore is measured as it emerges from the mine before any treatment or separation. This interpretation aligns with RA 7942, the Philippine Mining Act of 1995, which defines ‘ore’ as a ‘naturally occurring substance or material from which a mineral or element can be mined and/or processed for profit.’ According to the Court, the law plainly refers to ore in its unprocessed form, before the valuable mineral is separate from the ore itself.

Therefore, the Court emphasized the critical role of the DENR in protecting the environment. The Court stated that if the extraction measurement was done by measuring only the Ni-Co and excluding the gangue, small-scale miners are virtually given the license to continuously collect large volumes of ore until the 50,000 DMTs of Ni-Co limit is met. Because mining, whether small or large-scale, raises environmental concerns, allowing such a scenario will further cause damage to the environment such as erosion and sedimentation, landslides, deforestation, acid rock drainage, etc. Thus, the Court upheld the DENR’s interpretation of the 50,000 MT limit, recognizing its authority and expertise in managing the country’s natural resources and protecting the environment.

FAQs

What was the key issue in this case?	The central issue was whether the 50,000-MT annual production limit for small-scale mining operations, as defined in PD 1899, was valid and applicable, and how ‘ore’ should be defined for purposes of this limit. The mining companies argued that PD 1899 was repealed by RA 7076 and that the limit only applied to the extracted minerals, not the total mined material.
Did the court find the 50,000 MT limit valid?	Yes, the Supreme Court upheld the validity of the 50,000 MT annual production limit. The court stated that this limit applies uniformly to both small-scale mining permits issued under PD 1899 and small-scale mining contracts under RA 7076 due to the DENR’s authority to harmonize the laws.
How did the court define ‘ore’ in this case?	The court defined ‘ore’ as the ‘run-of-mine ore,’ which includes the total mass extracted from the mine before any processing or separation of minerals. This means the 50,000 MT limit applies to the total weight of the mined material, not just the weight of the extracted minerals like Nickel and Cobalt.
What is the significance of DENR’s role in this ruling?	The ruling emphasizes the DENR’s primary role in managing and conserving the country’s natural resources and the power to regulate mining activities. It recognizes the DENR’s authority to set limits and define terms to ensure sustainable and environmentally responsible mining practices.
What is the practical impact of this ruling on small-scale miners?	Small-scale miners must adhere to the 50,000 MT annual production limit based on the total mass extracted, including gangue. This ensures miners cannot argue that only extracted minerals are counted, preventing excessive mining and environmental damage.
What was the argument of the mining corporations regarding the equal protection clause?	The mining corporations argued that the absence of a production limit in RA 7076 created an unequal classification between miners under the two laws, violating the equal protection clause. The Supreme Court rejected this argument by stating that the DENR had harmonized the two laws and eliminated any potential equal protection concerns.
Why did the court reject the mining corporations’ interpretation of ‘ore’?	The court rejected the mining corporations’ interpretation because it would allow miners to extract vast quantities of material, leading to environmental damage, as they would only be limited by the weight of the extracted minerals. This interpretation would undermine the DENR’s environmental protection mandate.
What does this ruling mean for environmental protection in mining?	This ruling reinforces environmental protection in mining by ensuring that small-scale mining operations are subject to production limits that prevent over-extraction and environmental degradation. It empowers the DENR to enforce these limits and protect the country’s natural resources.

In conclusion, the Supreme Court’s decision in this case clarifies the regulatory framework for small-scale mining, reinforcing the DENR’s authority to impose and enforce production limits for environmental protection. It resolves ambiguities in the definition of ‘ore,’ providing a clear standard for measuring extraction and ensuring the sustainable use of mineral resources.
