Yoquivo Historic Core Sampling Reveals 519m of Elevated Silver-Gold Grades
Advance Metals has revealed compelling results from historic core sampling at its Yoquivo Silver-Gold Project, highlighting extensive high-grade mineralisation and potential for both underground and bulk tonnage resources. An upgraded JORC resource estimate is imminent.
- Historic core sampling of ~5,000m completed at Yoquivo
- 3,516m of assays received, with 519m showing elevated silver-gold grades
- Multiple high-grade intervals exceeding 100g/t silver equivalent identified
- Broad mineralised zones suggest potential for open-pit and underground mining
- JORC resource upgrade planned incorporating new data; ongoing drilling assays pending
Historic Core Sampling Unlocks New Potential
Advance Metals Limited (ASX – AVM) has delivered a significant update on its Yoquivo Silver-Gold Project in Chihuahua, Mexico, following an extensive program of historic core sampling. The company has analysed approximately 5,000 metres of previously unassayed diamond drill core, receiving assay results for 3,516 metres to date. Impressively, 519 metres of this material returned elevated silver and/or gold grades above 4 grams per tonne silver equivalent (AgEq), revealing zones of mineralisation that had not been recognised in earlier exploration efforts.
High-Grade Intervals and Broad Mineralised Zones
The sampling program has identified multiple high-grade intervals exceeding 100g/t AgEq across 13 separate drill holes. Notable highlights include a 0.9-metre intercept grading 766g/t AgEq (426g/t silver and 4.4g/t gold) and an 8.75-metre interval at 150g/t AgEq with an internal 1.1-metre section grading 848g/t AgEq. Beyond these high-grade pockets, the data reveals exceptionally broad zones of contiguous mineralisation in the central portion of the deposit, with intervals such as 144 metres at 93g/t AgEq and 66.45 metres at 83g/t AgEq. These broad intersections suggest the deposit may support both high-grade underground mining and bulk tonnage open-pit scenarios.
Strategic Implications and Upcoming JORC Upgrade
Advance Metals’ Managing Director and CEO, Dr Adam McKinnon, emphasised the value of the historic core sampling approach, noting it as a low-cost method to unlock previously unrecognised mineralisation without new drilling. The company plans to integrate these new assay results with recent drilling data into an upgraded JORC-compliant resource estimate. This upgrade will explore a range of cut-off grades, potentially expanding the resource to include both underground and open-pit mining opportunities, drawing parallels to the nearby Agnico Eagle Pinos Altos Mine.
Ongoing Exploration and Project Security
Regional exploration and resource expansion drilling continue at Yoquivo, with assays pending for multiple holes. The project’s tenements are in good standing, held 100% by Advance Metals through its Mexican subsidiary, with secure access agreements in place with local landholders. The company’s systematic approach to sampling, rigorous assay protocols, and detailed geological logging underpin confidence in the emerging resource potential.
Looking Ahead
As Advance Metals prepares to release its upgraded JORC resource estimate, the market will be watching closely to see how the new data reshapes the project’s economic outlook. The combination of high-grade veins and broad mineralised zones could position Yoquivo as a compelling silver-gold development opportunity in the region.
Bottom Line?
Advance Metals’ historic core sampling at Yoquivo sets the stage for a resource upgrade that could redefine the project’s scale and mining potential.
Questions in the middle?
- How will the upcoming JORC resource upgrade quantify the newly identified broad mineralised zones?
- What impact will pending assay results from ongoing drilling have on the overall resource model?
- Can Advance Metals confirm the feasibility of both open-pit and underground mining scenarios at Yoquivo?
