Colombia And Argentina To Yield Major Gold Discoveries As Orosur Mining Drills Deeper

Orosur Mining, a South American-focused mineral exploration company, has made significant strides in its drilling work at the Anzá gold exploration project in Colombia and the El Pantano gold/silver exploration project in Argentina. These advancements bring the company closer to unlocking the potential of these projects, which could lead to major discoveries and expansions in the region.

At Anzá, Orosur is making progress towards a NI43-101-compliant mineral resource estimate (MRE) for the Pepas prospect. The MRE is expected to be completed by January 2026, marking an important milestone for the project. This estimate will provide a more detailed understanding of the deposit’s size and quality, which will inform future exploration and development plans.

The Anzá project is a significant one for Orosur, as it holds full ownership of approximately 330km² of exploration titles in the Mid-Cauca gold belt. The company acquired these titles in November 2024 from previous joint venture (JV) partners Newmont Mining and Agnico Eagle Mines. This move has given Orosur a chance to pursue its own vision for the project, free from external influence.

The company’s focus at Anzá is on three main targets: Pepas, APTA, and El Cedro. Each of these targets presents opportunities for significant gold discoveries, and Orosur is working diligently to explore them. The Pepas prospect is a particular area of interest, as it is a shallow, high-grade gold zone that the company plans to advance to an initial MRE.

The drilling program at Anzá was commenced in July 2025, with infill drilling focused on Pepas. This drilling has been crucial in defining the deposit limits and understanding the geology of the area. The external geological and resource consultants who visited the site in early November 2025 played a key role in supporting this work, providing quality assurance and quality control verification.

Following their recommendations, Orosur extended the final stages of the Pepas MRE drill-out program to include several additional holes beyond the current deposit envelope. This was done to better define the deposit limits and gain more valuable structural information. Notably, hole PEP-067 returned expected lower-grade halo mineralization outside the deposit envelope, providing insights into the project’s potential for further expansion.

The drilling results at Anzá are promising, with significant gold discoveries reported at various depths. Hole PEP-067, drilled within the deposit envelope, yielded 83.7m at 4.29 grams per tonne (g/t) gold from surface. This result suggests that the Pepas prospect has substantial potential for gold production.

Meanwhile, at El Pantano, Orosur is making progress in its drilling work, which is expected to be completed by the end of January 2026. The project is a significant one for the company, as it holds 51% ownership under a JV agreement with Deseado Dorado. The joint venture spans roughly 550km² within the Deseado Massif, close to other notable gold mines in the region.

Orosur’s focus at El Pantano is on confirming the presence of a low-sulfidation epithermal mineral system. This type of system is known for producing high-grade gold and silver deposits, making it an attractive target for exploration and development. The drilling program has so far reported seven holes, with samples from the first five submitted for fire assay gold analysis and multi-element analysis.

The results from El Pantano are promising, with the discovery of a previously unknown mineral system at the project site. This finding presents significant opportunities for Orosur to expand its operations in Argentina. However, the company acknowledges that further exploration is needed to fully understand the potential of this system.

Orosur CEO Brad George expressed his enthusiasm about the project’s progress, stating: “Pepas is now in the final mile of its MRE process and the pieces are coming together for a January report.” He also highlighted the importance of exploring new targets at Anzá, once the rig is freed up later in December.

The company’s exploration efforts are not without risk. Drilling undrilled projects always carries high risks, but Orosur has shown its ability to navigate these challenges successfully. As George noted, “Drilling at El Pantano was high-risk, but we have hit what we hoped to hit – a previously unknown mineral system.” Now, the company must focus on refining its understanding of this system and moving forward with development plans.

The discovery of new mineral deposits and the expansion of existing ones have a direct impact on economies around the world, particularly those reliant heavily on the mining industry. The potential for growth at Anzá and El Pantano presents opportunities not just for Orosur but also for local communities and countries in South America.

Orosur’s progress has caught the attention of investors and stakeholders worldwide, who are eagerly watching its developments closely. As Orosur continues to explore these projects, it will be essential to monitor its progress closely and stay up-to-date with any changes or updates that may impact its project timeline or resource estimates.

The growth of the global mining industry depends on discoveries like those at Anzá and El Pantano. These projects have the potential to unlock new resources, drive economic growth, and create jobs in local communities.

With significant exploration efforts underway at Anzá and El Pantano, Orosur Mining is poised to make a lasting impact on the gold exploration sector in South America. The company’s focus on discovering high-grade gold deposits positions it well to capitalize on the growing demand for precious metals.

The global mining industry is facing increasing pressure due to factors such as inflation, interest rate hikes, and changing environmental regulations. In response, companies are focusing on efficiency, sustainability, and cost-effectiveness to ensure long-term viability.

Orosur’s commitment to advancing its projects despite these challenges demonstrates the company’s resilience and determination. As the global mining industry continues to evolve, it is essential for companies like Orosur to adapt and innovate to remain competitive.

With significant gold discoveries on the horizon, this is an exciting time for Orosur and investors alike. The discovery of new mineral deposits has a direct impact on economies around the world, particularly those reliant heavily on the mining industry.

Investors are keenly watching Orosur’s progress at Anzá and El Pantano due to its potential to unlock new gold deposits in South America. The company’s efforts to explore these projects have put it firmly on the map as a significant player in the region.
