Highlights

  • Mithril Silver and Gold has extended high-grade silver-gold mineralisation along the Copalquin-Zaragoza structure in Durango, Mexico.
  • Untested ground between the Zaragoza target, the Refugio resource area and the historical San Manuel mine points to a longer potential corridor.
  • The company's annual drilling programme is nearly complete, with assays pending and a scoping study underway on its maiden resource area.

Precious metals explorers have attracted renewed attention among Australian Market Participants as silver and gold remain in focus across global markets. Within the wider universe of Gold Stocks on the ASX, Mithril Silver and Gold Limited (ASX:MTH) has released further step-out drilling results from the Zaragoza target at its Copalquin property in Durango State, Mexico. The update extends the defined high-grade strike along the Copalquin-Zaragoza structure and outlines untested ground that could connect the target with the company's Refugio resource area to the northwest and the historical San Manuel mine to the southeast. The results arrive as the company nears the end of its annual drilling campaign and advances a scoping study, placing it among the ASX-listed explorers building a district-scale case in Mexico's Sierra Madre.

Step-Out Drilling Lengthens the Zaragoza Strike

Mithril reported that step-out drilling has lengthened the defined mineralised strike along the Copalquin-Zaragoza structure, with mineralisation hosted in a pair of sub-parallel veins sitting a short distance apart. The company has been testing extensions of these veins in regular lateral steps along strike, and the latest holes confirmed the continuation of high-grade silver and gold.

Several intercepts returned narrow but very high-grade silver and gold, including a southeast step-out that the company highlighted as particularly significant. The reported interval lengths are downhole measurements, and further drilling is needed to establish true widths. The company also noted that some holes intersected post-mineral dykes or weaker mineralisation, a reminder that grade continuity along structures of this kind can vary.

Untested Ground Toward Refugio and San Manuel

A key element of the update is the open ground on either side of the drilled zone. Mithril said the projected structure remains untested for a meaningful distance northwest toward the Refugio area, which hosts its existing resource, and for a similar distance southeast toward San Manuel. Taken together, this outlines a potential corridor that the company believes could link several targets along the same trend.

San Manuel is described as among the largest historical underground producers in the Copalquin district. Mithril has completed additional geological mapping around the old workings, and a substantial share of channel samples returned gold-equivalent grades above the company's reporting threshold. Results from surface and underground workings at San Manuel were gold-rich, in contrast with the silver-dominant veins being drilled at Zaragoza, which suggests metal zoning along the broader system.

Drilling Programme Nears Completion

Mithril has a pair of rigs operating at Copalquin and has completed almost all of its budgeted drilling for this year. Assays for several holes are still pending, meaning further results could emerge in coming weeks.

Managing director John Skeet said the company is focused on unlocking the potential between these targets while advancing the scoping study on its Refugio resource. Mithril is also examining possible connections between the Refugio area and the Zaragoza target, which could shape how the district is assessed in future technical work.

Resource Base and Scoping Study

The Refugio area hosts a mineral resource estimate across indicated and inferred categories, reported on a gold-equivalent basis using mining-shape-constrained estimates that include expected dilution. A scoping study, which the company also refers to as a preliminary economic assessment, is underway and targeted for completion early next year. Mithril holds an option over the Copalquin concessions that it may exercise under the terms of its agreement with the vendor.

It is important to distinguish between the categories of mineralisation discussed. The Refugio resource is a formal estimate, while the Zaragoza and San Manuel areas remain at the exploration stage and are not yet part of any resource. A scoping study is a preliminary assessment and does not establish reserves.

Risks and Sector Context

As with any exploration-stage company, Mithril faces risks including drilling outcomes, metallurgical performance, permitting in Mexico, funding requirements and movements in precious metal prices. Narrow vein systems can be challenging to model, and the commercial significance of high-grade intercepts depends on continuity and true widths.

More broadly, ASX-listed explorers with projects in Latin America continue to draw interest as companies seek high-grade silver and gold systems, though jurisdictional and operational risks remain part of the assessment.

Building the Copalquin District Story

Mithril's latest results extend the Zaragoza strike and highlight untested ground linking it with the Refugio resource area and the historical San Manuel mine. With drilling nearly complete, assays pending and a scoping study in progress, the company is assembling a district-scale picture at Copalquin. For Australian market participants following the ASX precious metals sector, the update illustrates how step-out drilling and historical workings can shape exploration narratives, while exploration and development risks remain.
