Untested Yoquivo Core Reveals High-Grade Mineralisation, Drilling Set to Resume
Advance Metals has revealed compelling high-grade silver and gold mineralisation in previously unsampled historic core at its Yoquivo project in Mexico, confirming significant upside potential. Initial assays from a targeted sampling program returned grades up to 848g/t silver equivalent, setting the stage for a resource upgrade in early 2026.
- Over 6,300m of historic core at Yoquivo identified as previously unsampled
- Initial assays from 222.7m across 11 holes confirm high-grade silver-gold mineralisation
- Peak grades include 1.1m at 848g/t silver equivalent in hole YQ-022-025
- Ongoing sampling and drilling to inform updated geological model and JORC Resource
- Diamond drilling recommencement imminent with rig mobilising shortly
Historic Core Reveals Untapped Potential
Advance Metals Limited (ASX – AVM) has delivered an encouraging update from its Yoquivo Silver-Gold Project in Chihuahua, Mexico, by confirming high-grade mineralisation in previously unsampled historic diamond core. The company’s recent sampling program targeted over 6,300 metres of legacy core; representing more than half of the historic drilling; that had not been assayed before.
The initial batch of assay results, covering 222.7 metres of core from 11 holes in the southern Pertenencia structure, has validated the strategy. Notably, hole YQ-022-025 returned an exceptional 1.1 metres grading 848 grams per tonne (g/t) silver equivalent, within a broader 2.05-metre interval at 480 g/t AgEq. Another hole, YQ-022-003, yielded 4.45 metres at 115 g/t AgEq, including a higher-grade 0.95-metre section at 249 g/t AgEq.
Strategic Sampling to Enhance Resource Understanding
These results highlight the selective nature of previous sampling by earlier explorers, which left substantial mineralisation untested. Advance’s Managing Director, Dr Adam McKinnon, emphasised that the initial findings represent only a fraction of the unsampled core and expressed optimism about further discoveries as the program progresses.
The company’s technical team is actively relogging and sampling additional core from the central and northern parts of Pertenencia, with multiple assay batches pending. These efforts, combined with recent drilling results, will feed into an updated geological model and underpin an upgraded JORC-compliant resource estimate expected in the first quarter of 2026.
Preparing for Next Phase of Drilling
Advance Metals is also advancing site preparations for the recommencement of drilling at Yoquivo, with a diamond rig expected to arrive shortly. This next phase aims to extend and better define the high-grade zones identified through both historic core sampling and recent drilling campaigns.
The Yoquivo project, situated within the prolific Sierra Madre Occidental volcanic belt, hosts multiple epithermal silver-gold vein systems. The Pertenencia structure, where the new assays originate, is one of four principal vein systems that have been mapped over strike lengths exceeding 3,000 metres.
Outlook and Market Implications
With the discovery of significant high-grade mineralisation in previously overlooked core, Advance Metals is poised to unlock additional value at Yoquivo. The pending assay results and forthcoming drilling will be critical in defining the scale and quality of the resource, potentially enhancing the project’s attractiveness to investors and partners.
Bottom Line?
Advance Metals’ ongoing core sampling and imminent drilling at Yoquivo could redefine the project’s resource potential, with market eyes now on upcoming assay results and the 2026 resource upgrade.
Questions in the middle?
- How extensive is the high-grade mineralisation across the unsampled core beyond the initial batch?
- What impact will the new assay results have on the upcoming JORC Resource upgrade?
- How soon will drilling results complement the core sampling to refine the geological model?
