Tocvan’s 2025 Year in Review

## Tocvan Ventures Charts Course for Production: Gran Pilar Project Delivers Key Milestones in 2025

Tocvan Ventures Corp. (OTCQB:TCVNF) has concluded a transformative year at its Gran Pilar gold-silver project in Sonora, Mexico, signaling a significant shift from pure exploration to tangible development progress. The company’s 2025 operational review highlights critical achievements, including the crucial permitting for a decade-long, 50,000-tonne capacity pilot heap-leach facility. This regulatory green light, coupled with expanded high-grade drilling discoveries and the commencement of pilot mine infrastructure, firmly positions Tocvan on a path toward near-term production.

The Gran Pilar project, spanning over 22 square kilometers, has been the focus of intensive exploration and development activities. Tocvan’s exploration strategy has centered on two primary targets: the South Block, an extension of the historic Main Zone, and the largely untested North Block, a significant 3.2 km by 1.5 km alteration zone.

Throughout 2025, drilling campaigns yielded impressive results. Notable intercepts include 83.5 meters grading 1.3 grams per tonne of gold (g/t Au), which encompassed a high-grade interval of 9.7 meters at 10.3 g/t Au. Further expanding the project’s potential, another significant drill hole returned 106.8 meters of 0.6 g/t Au, including a concentrated section of 3.1 meters grading 19.4 g/t Au. These results demonstrate robust mineralization across substantial widths, bolstering confidence in the project’s economic viability.

Metallurgical testing has further enhanced the project’s outlook. Composite samples have demonstrated rapid and high recovery rates, achieving 95–99% for gold and 73–97% for silver when subjected to gravity and agitated leach processes. These figures are highly encouraging for heap-leach operations, the planned method for the pilot facility.

However, the recent bulk sample from the Pilar area presented a more nuanced picture. While the sample yielded a head grade of 1.9 g/t Au, the gold recovery over a 46-day leach period was reported at 62%. This contrasts with the higher recoveries seen in laboratory tests and highlights potential variability in recovery rates for larger-scale operations. The fine fraction of this sample, however, indicated rapid recovery via agitated leach, suggesting that optimizing particle size and leach conditions will be a key focus for future processing.

Tocvan has also made strategic corporate advancements to support its development trajectory. Key management appointments have been made to strengthen the team, and the company has secured significant funding to underwrite ongoing operations and future growth initiatives. Discussions with regional producers regarding potential collaborations and due diligence are also advancing, signaling external interest in the Gran Pilar project.

The company’s 2025 timeline was marked by a series of strategic advances:

* **Early Year:** Commenced core drilling at the Pilar Main Zone and initiated surface exploration, expanding known mineralization targets.
* **Spring:** First RC drilling in the northern expansion area delivered high-grade intercepts, including 106.8 meters at 0.6 g/t Au, and a significant core drill intercept of 83.5 meters at 1.3 g/t Au.
* **Mid-Year:** Achieved a notable silver intercept of 42.7 meters grading 41 g/t Ag. Crucially, the company secured permits for all drilling and extraction activities, followed by the critical 10-year permit for the 50,000-tonne pilot heap-leach facility and associated infrastructure.
* **Late Year:** Strengthened the corporate team, commenced field work and airborne magnetics surveys to refine exploration strategies, and began pilot mine trenching and infrastructure setup with community approval.

The Gran Pilar project’s geological setting features extensive alteration zones and historic workings, particularly in the North Block, which spans a 3.2 km by 1.5 km area. Recent drone magnetic surveys have identified structural complexities in the South Block that align with permitted drill targets, enhancing the exploration strategy.

Looking ahead, Tocvan is poised to leverage these 2025 achievements. The permitted pilot facility represents a significant de-risking event, allowing the company to transition from resource definition to demonstrating economic viability through controlled production. The ongoing exploration in both the South and North Blocks promises to further delineate and potentially expand the known gold and silver resources. With the company’s strategic focus on unlocking value at Gran Pilar, the coming year is expected to be pivotal in its journey toward becoming a producing gold and silver company.
