  • Hole GV-26-008 at the Advance Metals Gavilanes Silver Project returned 1.0m at 4,120g/t Ag — the highest individual silver assay grade in the company's entire drilling programme to date.
  • The same hole delivered 12.0m at 3.8% Zn and 3.7% Pb from 98.5m, including 5.3m at 7.7% Zn and 6.3% Pb — the highest-grade zinc-lead intersection recorded at Gavilanes.
  • Three southern holes (GV-26-005, GV-26-006, GV-26-007) confirmed gold mineralisation extending beyond the silver-dominant core, pointing to a vertically zoned polymetallic system across silver, gold, copper, zinc and lead.
  • The mineralised system remains open at depth and to the southwest, with GV-26-009 already drilled to test westerly extensions approximately 100m north of GV-26-008 and assays pending.
  • A maiden JORC Mineral Resource is targeted for Q4 CY2026, building on an existing Foreign Estimate of 22.4Moz AgEq at 246g/t AgEq across 136 sq km — alongside Advance's separately established 33Moz AgEq Inferred JORC Resource at Yoquivo.

Record silver grades headline Gavilanes’ best drilling results yet

Advance Metals (ASX: AVM) has returned its highest individual silver assay grade to date at the 100%-owned Gavilanes Silver Project in Mexico, with new hole GV-26-008 delivering 4.6m at 945g/t Ag, 1.4% Zn and 1.0% Pb from 66.7m, including 1.0m at 4,120g/t Ag, 5.7% Zn and 4.1% Pb. A second interval deeper in the same hole returned 12.0m at 21g/t Ag, 3.8% Zn and 3.7% Pb from 98.5m, including 5.3m at 36g/t Ag, 7.7% Zn and 6.3% Pb — the highest-grade zinc-lead intersection encountered at the project to date.

The mineralised system remains open at depth and to the southwest. Gavilanes sits 23km from First Majestic Silver Corp’s world-class San Dimas Mine, placing it squarely within one of Mexico’s premier silver-gold districts.

Dr Adam McKinnon, Managing Director and CEO

“At over 4,000g/t silver, GV-26-008 returned the highest individual silver assay grade in Advance’s program to date and one of the best ever recorded at the project. The hole also returned the highest grade zinc-lead interval encountered at the Project to date, including 5.3 metres at 14% Zn+Pb — highlighting the potential for significant base metal credits as the mineralised footprint grows.”

GV-26-008 drilling results in full

GV-26-008 was drilled directly below the high-grade silver mineralisation previously intersected in GV-26-004, confirming depth continuity within the Descubridora structure. The upper interval contains the highest individual silver assay returned by Advance’s drilling program at Gavilanes to date, while the lower interval represents the highest-grade zinc-lead intersection at the project.

Three southern holes — GV-26-005, GV-26-006 and GV-26-007 — demonstrate gold mineralisation extending beyond the silver-dominant core, pointing to a broadening polymetallic system:

  • GV-26-007: 2.4m at 2.0g/t Au, 21g/t Ag, 1.2% Zn and 2.2% Pb from 14.4m; and 6.0m at 1.4g/t Au and 4g/t Ag from 127.2m
  • GV-26-006: 3.6m at 0.8g/t Au and 30g/t Ag from 136.8m
  • GV-26-005: 1.9m at 1.5g/t Au and 16g/t Ag from 109.35m

Why Gavilanes is emerging as a world-class silver district play

The Sierra Madre Occidental — Mexico’s silver backbone

Gavilanes sits within the Sierra Madre Occidental Volcanic Belt, the geological backbone of Mexico’s silver industry and host to many of the country’s major precious metal deposits. The project’s location 23km from First Majestic Silver’s San Dimas Mine is particularly significant: San Dimas has produced 745 million ounces of silver and 11 million ounces of gold across more than 125 recognised veins, and still hosts significant resources.

Gavilanes District Comparison

A polymetallic system growing in every direction

Gavilanes is classified as a low- to intermediate-sulphidation epithermal deposit. In plain terms, that means silver, gold and base metal mineralisation concentrated in high-grade veins and breccia zones — the deposit style that hosts many of the world’s major silver mines.

What makes Gavilanes particularly compelling for investors is the changing metal distribution with depth. Near-surface drilling has returned high-grade silver; intermediate-depth holes GV-26-002 and GV-26-003 intersected broad copper-gold-silver zones; and now GV-26-008 has added strong zinc and lead at greater depth. The result is a layered polymetallic system with potential credits across multiple metals.

The copper-gold-silver zones encountered in holes GV-26-002 and GV-26-003 at intermediate depths were the first indication that Gavilanes hosts a vertically zoned polymetallic system rather than a single-metal silver play.

The project already hosts a Foreign Estimate of 22.4 million ounces of AgEq at 246g/t AgEq across 136 sq km — but Advance’s drilling to date has been concentrated on only a portion of the broader project area. (Note: The Foreign Estimate is not compliant with the 2012 JORC Code. A Competent Person has not yet done sufficient work to classify it as a Mineral Resource or Ore Reserve. It is uncertain that, following further evaluation and exploration, the Foreign Estimate will be able to be reported in accordance with the JORC Code 2012.)

What comes next — maiden JORC Resource targeted for Q4 CY2026

Drilling at the project is ongoing, with assays pending for hole GV-26-009, which was drilled to test further westerly extensions to the high-grade system, approximately 100m north of GV-26-008.

Metallurgical testwork has also commenced on both silver-dominant and polymetallic samples, assessing potential recoveries of silver, gold, copper, zinc and lead. This is a key de-risking step ahead of the planned maiden JORC Mineral Resource, which is targeted for Q4 CY2026, building on the existing Foreign Estimate base of 22.4Moz AgEq.

The company’s next steps pipeline is as follows:

  1. Receive and interpret assays from GV-26-009 and continue drilling targets to the west and at depth
  2. Continue systematic testing of the Descubridora structure over up to 500m of strike
  3. Commence drilling of additional priority targets including San Nicolas
  4. Integrate new lithological, structural, geochemical and assay data into the updated Gavilanes geological model
  5. Complete metallurgical testwork to assess potential recoveries of Ag, Au, Cu, Zn and Pb
  6. Incorporate all results into the planned maiden JORC Mineral Resource, targeted for Q4 CY2026

Dr Adam McKinnon, Managing Director and CEO

“Following the establishment of a 33Moz AgEq Inferred JORC Mineral Resource at Yoquivo, Gavilanes is becoming an increasingly important part of Advance’s broader Mexican resource growth strategy.”

With two advancing Mexican projects — Yoquivo carrying a 33Moz AgEq Inferred JORC Mineral Resource and Gavilanes building towards its own maiden resource estimate — Advance Metals is positioning itself as a dual-project silver explorer with a clear resource growth timeline in one of the world’s premier silver jurisdictions.

For investors wanting the full context behind Advance’s dual-project strategy, our dedicated guide to the 33Moz AgEq Inferred JORC Mineral Resource at Yoquivo walks through the resource estimation methodology, drill data underpinning the classification, and what the result means for the company’s broader 200Moz portfolio ambition.

Frequently Asked Questions

What is the Advance Metals Gavilanes Silver Project?

The Gavilanes Silver Project is a 100%-owned silver exploration project in Mexico held by ASX-listed Advance Metals (AVM), located 23km from First Majestic Silver's San Dimas Mine in the Sierra Madre Occidental Volcanic Belt. It hosts a Foreign Estimate of 22.4 million ounces of silver equivalent across 136 square kilometres, with a maiden JORC Mineral Resource targeted for Q4 CY2026.

What did hole GV-26-008 return at Gavilanes?

Hole GV-26-008 returned two significant intervals: an upper zone of 4.6m at 945g/t Ag, 1.4% Zn and 1.0% Pb from 66.7m — including 1.0m at 4,120g/t Ag, the highest individual silver assay in Advance's drilling programme — and a lower zone of 12.0m at 21g/t Ag, 3.8% Zn and 3.7% Pb from 98.5m, which is the highest-grade zinc-lead intersection at the project to date.

What is a low- to intermediate-sulphidation epithermal deposit?

A low- to intermediate-sulphidation epithermal deposit is a type of precious and base metal deposit formed at shallow crustal depths, characterised by high-grade silver, gold, and base metal mineralisation concentrated in veins and breccia zones. This deposit style hosts many of the world's major silver mines, including San Dimas, which has produced 745 million ounces of silver.

When is Advance Metals targeting a maiden JORC Resource at Gavilanes?

Advance Metals is targeting a maiden JORC Mineral Resource at Gavilanes for Q4 CY2026, building on an existing Foreign Estimate of 22.4Moz AgEq at 246g/t AgEq. Metallurgical testwork has commenced and drilling is ongoing, with assays pending from hole GV-26-009.

What is the difference between a Foreign Estimate and a JORC Mineral Resource?

A Foreign Estimate is a resource estimate prepared under a non-Australian reporting standard and has not been verified by a Competent Person under the JORC Code 2012, meaning it cannot be relied upon in the same way as a formal Mineral Resource or Ore Reserve. Advance Metals has explicitly noted that it is uncertain whether the 22.4Moz AgEq Foreign Estimate at Gavilanes will ultimately be reportable under JORC 2012.
