Eloro Resources Further Expands Extent of Potential Starter Pit Zone, Intersecting 90 metres grading 61.05 g/t Silver and 0.20% Tin at its Iska Iska Project, Potosi Department, Southern Bolivia
None
The November 19, 2025, news release provides additional assay results from the definition diamond drilling program at the Iska Iska Project in Bolivia. The results are from two holes, DSB-91 and DSB-92, drilled on the eastern and far-eastern boundary of the Potential Starter Pit Zone at the Santa Barbara deposit.
Key intercepts include: - DSB-92: 90.0 metres grading 61.05 g/t silver (Ag) and 0.20% tin (Sn). - DSB-91: Multiple polymetallic intervals, including 151.5 metres grading 1.41% zinc (Zn) and 13.35 g/t Ag, and 136.5 metres grading 0.23% Sn, 0.92% Zn, and 0.84% lead (Pb).
Management states these results extend the known mineralization at least 50-100 metres beyond the current potential starter pit shell. This expansion is expected to be incorporated into an updated Mineral Resource Estimate (MRE) for a planned Preliminary Economic Assessment (PEA). The company also noted two additional holes from the program have assays pending.
This news is materially positive. It builds upon a year of successful definition drilling aimed at upgrading and expanding the initial MRE from October 2023. The primary goal of this drill program was to demonstrate continuity and expand the mineralized footprint, and these results achieve that objective.
- Confirmation of Expansion: The key takeaway is the successful extension of the mineralization to the east, outside the previously defined pit shell. This directly adds potential tonnage to the project and de-risks the concept of a larger starter pit, which is crucial for the upcoming PEA.
- Grade and Continuity: The grades and lengths are consistent with previous positive results from 2025. For example, the 90-metre intercept in DSB-92, while not as high-grade as the bonanza silver hit in March (DSB-75: 9.75m of 962 g/t Ag), is a long, bulk-tonnage style interval that adds significant value. It confirms the presence of both the Sn-Ag domain and the Ag-Zn-Polymetallic domain, highlighting the project's polymetallic nature.
- Alignment with Strategy: The results are perfectly in line with the company's stated strategy of systematically drilling to increase the resource size and confidence level before commencing a PEA. Each successful step-out hole like this reduces exploration risk and increases the project's potential economic viability.
- Progression: Reviewing the news from oldest to newest shows a clear, positive progression. The major tin discovery in January 2025 (DSB-72) was followed by a series of successful infill and step-out holes throughout the year that consistently expanded the known zones. This latest news is another solid step in that progression, confirming the geological model and suggesting the deposit remains open.
While not a "game-changing" discovery hole on its own, this news provides strong, positive confirmation of the project's expansion potential and will be viewed favorably by the market as it directly supports the path toward a robust PEA.
Eloro Resources Ltd. is a Canadian mineral exploration and development company. Its flagship asset is the Iska Iska silver-tin polymetallic project located in the Potosí Department of southern Bolivia. Eloro has an option to acquire a 100% interest in the project, which is described as being royalty-free.
The project is a large porphyry-epithermal complex that the company believes has the potential to host two distinct world-class deposits: a silver-zinc-lead dominant system and an adjacent high-grade tin system. The company published an initial Inferred Mineral Resource Estimate in October 2023 and has spent 2025 conducting a definition drilling program to upgrade and expand this resource in preparation for a PEA.
