Highlights

  • Andean Silver (ASX:ASL) continues to expand its Cerro Bayo silver-gold project through ongoing exploration success.
  • Recent drilling has delivered high-grade silver-equivalent intercepts across multiple target areas.
  • The company reported a significant increase in its mineral resource base during 2026.
  • Development studies remain a key milestone as Andean Silver progresses towards potential mine restart decisions.

Andean Silver Limited (ASX:ASL) continues to build its position as a silver-focused exploration company through ongoing drilling success at its 100 per cent-owned Cerro Bayo project in southern Chile. The company has been advancing a historic silver-gold Mining district through resource growth, exploration activity and studies aimed at assessing future development potential.

The project has attracted market attention due to a combination of high-grade drill results, a growing mineral resource base and exposure to a stronger silver market environment. However, Andean Silver remains a pre-production explorer, with future progress dependent on exploration outcomes, development studies and funding requirements.

What Just Happened?

Andean Silver has continued its district-wide drilling campaign at Cerro Bayo, with exploration activities focused on extending known mineralisation and identifying additional resource potential.

The company’s 2026 exploration program includes approximately 60,000 metres of drilling across the project, supported by multiple drill rigs. The program is designed to test existing deposits, expand mineralised zones and provide further information for future development studies.

The most recent confirmed high-grade drilling results were released on 7 July 2026, with results from the Trinidad vein and Delia SE deposit highlighting the continued exploration potential of the Cerro Bayo system.

The company is also progressing towards a feasibility study targeted for mid-2027, representing an important milestone as it evaluates the potential transition from explorer to developer.

Digging Into the Numbers

The July 2026 drilling update included several high-grade intersections.

At the Trinidad vein, hole CBD342 returned 2.4 metres grading 15,558 grams per tonne silver-equivalent (AgEq), including a 1.4-metre interval grading 25,340 g/t AgEq. The intersection included 3,045 g/t silver and 268.6 g/t gold.

Additional Trinidad results included 2.5 metres at 500 g/t AgEq and 3.3 metres at 480 g/t AgEq. At the Delia SE deposit, hole CBD314B returned 3.1 metres at 3,356 g/t AgEq.

Earlier drilling at the Appaloosa Breccia target also identified broader mineralised zones. Hole CBD266 returned 46.4 metres at 219 g/t AgEq, including a higher-grade interval of 7.2 metres at 874 g/t AgEq.

These results contributed to resource growth, with Andean Silver reporting a mineral resource of 20 million tonnes at 211 g/t AgEq for approximately 136 million ounces of silver equivalent as at June 2026.

The company held cash of A$42.7 million as at 30 June 2026, supporting ongoing exploration and development activities. However, exploration expenditure continues to require significant funding as the company advances its project pipeline.

Why the Market Is Paying Attention

Andean Silver’s Cerro Bayo project combines exploration upside with the advantage of being located within a historic mining district that has previously supported silver-gold production.

The company’s exploration strategy has focused on expanding the resource base while identifying areas that could support a future development pathway. The planned feasibility study represents an important step in assessing project Economics and potential mine restart scenarios.

Silver market conditions have also contributed to increased interest in silver-focused companies. Demand expectations linked to industrial applications, renewable energy infrastructure and Investment demand have supported broader attention towards silver assets.

For Andean Silver, project-specific exploration performance remains the primary driver, with future value dependent on converting exploration success into a viable development opportunity.

The Bigger Story

Andean Silver, previously known as Mitre Mining Corporation, has repositioned itself as a focused silver exploration company through its Cerro Bayo project in Chile’s Aysén region.

The company has expanded its resource base, increased exploration activity and moved towards development studies while leveraging existing infrastructure within the historic mining district.

However, the company remains in the development stage and faces the typical challenges associated with exploration and mine development. High-grade drill results do not always translate directly into economic mine plans, particularly where mineralisation widths and continuity require further assessment.

Funding requirements also remain an important consideration. Continued exploration, feasibility work and potential development activities may require additional capital, which could impact Shareholder dilution.

What Investors Should Watch Next

  • Further updates from the Cerro Bayo drilling campaign and potential resource expansion.
  • Progress towards the feasibility study targeted for mid-2027.
  • Conversion of high-grade exploration results into broader, economically mineable mineral zones.
  • Cash management and future funding requirements.
  • Silver price movements and broader precious metals market conditions.

Conclusion

Andean Silver (ASX:ASL) continues to strengthen the Cerro Bayo development story through high-grade drilling results, resource growth and ongoing exploration activity. The project’s historic mining background, expanding resource base and silver market exposure provide the foundation for the company’s longer-term ambitions.

However, Andean Silver remains a pre-production explorer, meaning future success will depend on continued exploration results, development progress and access to funding. The next phase of work will focus on determining whether Cerro Bayo can advance from an exploration opportunity into a commercially viable mining project.
