How Tesoro Gold’s Latest Drilling is Redefining Ternera’s Gold Potential
Tesoro Gold’s latest drilling results reveal significant extensions of high-grade gold mineralisation at the Ternera deposit in Chile, promising a larger resource base ahead of an updated estimate.
- Broad, high-grade gold intercepts extend beyond current 1.3Moz resource boundary
- Rapidly growing southern mineralised zone confirmed by recent drilling
- Shallow northern extensions continue to expand with promising assay results
- Ongoing drilling aims to incorporate new zones into upcoming Mineral Resource Estimate
- Parallel progress on metallurgical testing and environmental permitting underway
Expanding the Ternera Gold Resource
Tesoro Gold Limited has announced compelling new assay results from its extensional and infill drilling program at the Ternera Gold Deposit, part of the El Zorro Gold Project in Chile. The company’s recent drilling campaign has delivered broad zones of high-grade gold mineralisation that extend well beyond the boundaries of the existing 1.3 million ounce Mineral Resource Estimate (MRE).
Notably, the southern extension of the deposit is rapidly growing, with drill holes such as ZDDH0378A and ZDDH00384 returning significant intercepts including nearly 64 metres at 1.26 grams per tonne gold and 51 metres at 1.13 grams per tonne gold. These results confirm the continuity and scale of mineralisation outside the current resource shell, positioning the southern zone as a key area of growth for Ternera.
Northern Extensions and Ongoing Exploration
In addition to the southern expansion, shallow mineralisation at the northern end of Ternera continues to show promise. Recent drill holes have intercepted gold grades exceeding 1.6 grams per tonne over several metres, suggesting that the deposit remains open along strike and at depth. This ongoing exploration focus aims to further define both northern and southern extensional targets to enhance the overall resource base.
Managing Director Zeff Reeves highlighted the strategic importance of these results, emphasizing that each new drill hole broadens the known mineralised footprint. The company is actively working to incorporate these extensions into the forthcoming MRE update, which will better capture the full size and potential of the Ternera gold system.
Supporting Project Development
Alongside drilling, Tesoro is advancing metallurgical test work to inform final plant design, a critical step toward project feasibility. Environmental permitting processes are also progressing to align with development timelines. With two drill rigs operating around the clock, the company is maintaining a robust exploration pace throughout 2025.
The El Zorro Gold Project benefits from its location in Chile’s Coastal Cordillera, a region known for world-class mineral deposits and established mining infrastructure. Tesoro’s 95% owned Chilean subsidiary holds a dominant stake in the project, underpinning the company’s confidence in advancing Ternera toward production.
Looking Ahead
While the true widths of mineralisation remain to be fully defined, the consistent high-grade intercepts and expanding zones signal a potentially larger and more valuable resource. Investors and analysts will be watching closely for the updated MRE and subsequent development milestones that could unlock significant value for Tesoro Gold.
Bottom Line?
Tesoro’s expanding gold zones at Ternera set the stage for a resource upgrade that could reshape the project’s future.
Questions in the middle?
- How will the upcoming Mineral Resource Estimate update quantify the newly discovered southern extensions?
- What impact will metallurgical test results have on the project’s processing strategy and economics?
- How might environmental permitting timelines influence the pace of Ternera’s development?
