IMPACT Silver Intersects 15.14% ZnEq over 3.07m Including 24.69% ZnEq over 1.47m at the Plomosas Mine
None
On November 20, 2025, IMPACT Silver announced additional high-grade drill results from the Juarez Zone at its Plomosas Mine in Mexico. The highlight intersection was 15.14% zinc equivalent (ZnEq) over 3.07 meters, which included a higher-grade portion of 24.69% ZnEq over 1.47 meters in hole UGMJ-2547. Other notable intercepts included high-grade zinc, lead, and silver over various widths.
Crucially, the company states that these intersections are extensions of the Juarez Zone and lie outside of the previously published mineral resource blocks. The CEO, Frederick Davidson, commented that the proximity of this mineralization to existing underground infrastructure allows for ready expansion of mining operations. The company currently has two drills testing near-mine targets and has begun exploring other targets along the property's six-kilometer trend.
The news is materially positive as it successfully demonstrates the company's ability to expand the mineralized footprint at its key growth asset, the Plomosas Mine.
- Execution on Strategy: Following a significant C$16 million financing in September 2025, a stated use of proceeds was to "accelerate resource definition drilling with the objective of extending the mine life" at Plomosas. These results show immediate and successful execution of that strategy.
- Economic Significance: Discovering mineralization that is an extension of current mining areas and close to existing infrastructure is highly significant. This should translate to lower capital costs and a shorter timeline to bring these tonnes into the mine plan, which is critical for a company still in the ramp-up phase.
- Grade Confirmation: The grades, with zinc equivalent values between 15% and 25%, are consistent with previously announced high-grade results from other zones at Plomosas (e.g., Santo Domingo, Tres Amigos). This consistency builds confidence in the geological model and the potential to continue finding high-grade pods to feed the mill.
- Context of Operations: In the first half of 2025, Plomosas was not yet profitable on an operating basis (direct costs per tonne exceeded revenue per tonne). A key path to profitability is increasing the mill head grade. Discoveries like this are precisely what is required to improve the mine's economics.
While these results are not a "game-changer" in that they don't represent a massive, standalone discovery, they are a crucial, value-additive step in de-risking the Plomosas operation and extending its mine life. It provides tangible evidence that the exploration model is working and that the capital raised is being deployed effectively. The market may view this positively as it addresses the key concern of mine life and profitability at this critical asset.
IMPACT Silver is a mineral producer with two primary assets in Mexico. 1. The Royal Mines of Zacualpan Silver-Gold District: This is the company's legacy asset, a 100%-owned 211-sq-km property that has been in production for over 18 years. It includes several producing mines and the 500 tpd Guadalupe processing plant. Recent high-grade silver discoveries, such as the Kena Vein, offer exploration upside. 2. The Plomosas Zinc-Lead-Silver Mine: This is the company's flagship growth project. Acquired in 2023, Plomosas is a historic high-grade zinc producer that the company has rehabilitated and is currently ramping up to its 200 tpd design capacity. The primary focus of recent corporate activity, including exploration and financing, has been on Plomosas to expand its resource and extend the mine life.
