El Brocal Seeks Extended Suspension of Tajo Norte Operations, Prioritizing Subterranean Mining and Navigating Regulatory Hurdles

Lima, Peru – Sociedad Minera El Brocal S.A.A., a key subsidiary of Compañía de Minas Buenaventura, has formally requested an additional two-year extension for the suspension of operations at its Tajo Norte open-pit mine. This significant request, submitted to the Ministry of Energy and Mines, underscores a strategic shift towards prioritizing subterranean mining activities at its Colquijirca unit in Pasco, while simultaneously navigating evolving environmental regulations and ongoing administrative proceedings.

The initial three-year suspension of Tajo Norte, which commenced in October 2023 and was slated to conclude in early October 2026, has now been proposed to extend until October 2028. This proposed extension reflects a calculated operational strategy by El Brocal, aimed at concentrating resources and capital on the Marcapunta underground mine. The company asserts that this focused approach will optimize extraction efficiency, enhance competitiveness in the short to medium term, and ultimately maximize value from its existing ore bodies.

During the extended suspension period, activities at Tajo Norte will be strictly limited to essential functions. These include ongoing exploration efforts to assess the potential of the area, the transportation of already accumulated ore to the concentrator plant, crucial water management operations, and routine maintenance and care tasks to ensure the site’s integrity. This deliberate phasing out of open-pit extraction signals a long-term commitment to the Marcapunta operation as the primary revenue generator for El Brocal’s Colquijirca unit.

A Strategic Pivot: The Marcapunta Imperative

The decision to seek an extended suspension of Tajo Norte is intrinsically linked to El Brocal’s strategic focus on the Marcapunta underground mine. The company’s operational planning prioritizes the efficient extraction of copper ore from Marcapunta, a move designed to streamline operations and boost profitability. By consolidating its efforts and resources on this subterranean asset, El Brocal aims to achieve significant operational efficiencies. This strategic reallocation of capital and human resources is intended to bolster the company’s competitive standing in the dynamic global mining market.

The rationale behind this pivot is rooted in the inherent characteristics of the Marcapunta mine, which has demonstrated consistent and increasingly robust copper production. The company’s operational reports indicate a growing capacity and efficiency in extracting copper from Marcapunta. This focus on the underground operation is not merely a short-term adjustment but a long-term strategy that seeks to leverage the known high-grade copper reserves within Marcapunta.

Navigating the Labyrinth of Environmental Approvals

The initial suspension of Tajo Norte was precipitated by significant delays in the processing and approval of a crucial modification to its Environmental Impact Study (EIS). This modification was intended to increase the permitted processing capacity to 25,000 metric tons per day. However, the approval process was severely hampered by the widespread disruptions caused by the COVID-19 pandemic. Furthermore, regulatory shifts introduced in 2022 concerning the evaluation of environmental studies added another layer of complexity, further delaying the necessary permits for Tajo Norte’s full operational resumption at the proposed capacity.

Despite these challenges impacting the open-pit operation, the subterranean mining at Marcapunta has proceeded without significant interruption. El Brocal has actively worked to enhance its production output from Marcapunta, demonstrating a capacity to adapt and thrive even amidst external regulatory and logistical hurdles. The company’s ability to maintain and even increase copper production from Marcapunta during this period highlights the resilience and strategic importance of its underground operations.

Financial Performance: A Tale of Two Quarters and Lingering Concerns

El Brocal’s financial performance in recent periods presents a nuanced picture. The company reported a notable increase of 5% in its operating revenues during the first nine months of 2024, reaching US$334.5 million. This positive financial trajectory is largely attributable to the strong performance of the Marcapunta underground mine, reinforcing the strategic decision to prioritize this operation.

However, the company’s financial health is also shadowed by an ongoing administrative sanctioning procedure initiated by Osinergmin, Peru’s energy and mining investment regulator. This procedure, commenced in October 2025, alleges infractions related to the Regulation of Occupational Safety and Health in Mining. Specifically, the concerns revolve around the alleged failure to update the hydrogeological study for the Colquijirca mining unit. El Brocal has been actively submitting supplementary information to Osinergmin, with submissions made in December 2025 and again in February and April 2026. As of the latest reporting, the company had not yet formally presented its defense in response to the initial procedural notification. This administrative process represents a potential risk that could impact future operations or incur financial penalties, adding a layer of uncertainty to the company’s outlook.

Production Figures: Meeting Expectations Amidst Adjustments

El Brocal’s production figures offer insights into the efficacy of its current strategy. In the first quarter of 2025, the company successfully produced 12,063 metric tons of copper, meeting its projected targets. This achievement underscores the operational robustness of the Marcapunta mine. Furthermore, the production of silver during the same period exceeded the company’s guidance. This outperformance in silver output is attributed to higher-than-anticipated ore grades, a result of a short-term strategic plan focused on mining blocks with elevated silver content. This demonstrates El Brocal’s agility in optimizing its production mix to capitalize on favorable geological conditions and market opportunities.

Despite these positive indicators, the company’s overall annual copper production for 2025 fell short of its revised guidance. This shortfall is attributed to delays encountered in the development of the Marcapunta mine itself. Consequently, the planned extraction of high-grade copper ore blocks has been rescheduled for the first quarter of 2026. This recalibration highlights the inherent complexities and potential for unforeseen delays in large-scale mining operations, even within a prioritized and seemingly well-managed segment.

A Forward-Looking Perspective: Exploration and Future Decisions

While the immediate focus is on the Marcapunta underground mine, El Brocal has not abandoned its interest in the Tajo Norte deposit. The company is actively maintaining a portfolio of exploration projects within the Colquijirca unit. Notably, exploration efforts have been concentrated in areas adjacent to Tajo Norte and in the Marca Punta Este sector. This sustained exploration activity suggests that the open-pit deposit remains a viable prospect for future exploitation, contingent upon market conditions and regulatory approvals.

The company has explicitly stated its intention to re-evaluate the resumption of Tajo Norte operations within the originally projected suspension timeframe. This indicates a strategic flexibility, allowing El Brocal to adapt its long-term plans based on evolving market dynamics, technological advancements, and the resolution of outstanding environmental and regulatory matters. The ultimate decision to recommence open-pit mining at Tajo Norte will be a complex calculus, factoring in the prevailing market prices for copper and other metals, the overall economic viability of the deposit, and the successful navigation of the remaining environmental permitting processes.

Implications for the Mining Sector and Regional Economy

The extension of the Tajo Norte suspension by El Brocal has several implications for the Peruvian mining sector and the regional economy of Pasco. Firstly, it signals a growing trend within the industry towards prioritizing underground mining operations, which are often perceived as having a lower environmental footprint and more predictable production profiles, especially in challenging terrains. This shift may encourage further investment and technological development in subterranean mining techniques within Peru.

Secondly, the reliance on Marcapunta for primary copper production means that the operational success and efficiency of this underground mine will be critical for El Brocal’s financial performance and its contribution to Buenaventura’s overall output. Any disruptions or underperformance at Marcapunta could have a ripple effect on the parent company.

Thirdly, the ongoing environmental permitting challenges and the administrative sanctioning procedure highlight the increasing scrutiny and regulatory complexity faced by mining companies in Peru. The successful resolution of these matters will be crucial for El Brocal’s long-term operational stability and its reputation within the industry.

Finally, while Tajo Norte operations are suspended, the continued exploration and maintenance activities ensure that the site remains a potential source of future economic activity and employment in the Tinyahuarco district. The long-term decision regarding Tajo Norte will ultimately depend on a confluence of factors including commodity prices, technological advancements in open-pit mining, and the successful navigation of Peru’s robust environmental and regulatory framework. El Brocal’s strategic maneuvers at Colquijirca offer a compelling case study in adaptive mining strategy in the face of evolving market demands and regulatory landscapes.
