Highlights

A$40 million placement completed in September 2026 to support Cerro Bayo work.
Cerro Bayo reported 136 million ounces of silver-equivalent mineral resources.
June 2026 half-year accounts recorded a A$11,563,862 loss after tax.
Restart preparation includes technical studies, drilling and infrastructure work.
The project remains non-producing, with study and permitting milestones outstanding.

Andean Silver Limited (ASX:ASL) is an Australian mineral exploration and development company focused on its wholly owned Cerro Bayo silver-gold project in southern Chile. Its recent A$40 million equity placement provides funding for further drilling and technical work as the company assesses the requirements for restarting operations at the project. The programme combines resource definition with planning for refurbishment of existing infrastructure.

Placement Supports Cerro Bayo Work

On 2 September 2026, Andean Silver Limited (ASX:ASL) announced a A$40 million placement comprising 16,326,531 shares at A$2.45 each. The company reported settlement on 8 September 2026. The proceeds were earmarked for exploration, work to upgrade resource confidence, restart planning and general working capital.

Based on the company’s reported A$42.7 million cash balance at 30 June 2026 and the gross placement proceeds, Andean Silver (ASX:ASL) presented pro-forma cash of approximately A$82.7 million. This is not the same as an audited post-placement cash balance because transaction costs and subsequent expenditure may affect available cash. The amount illustrates the funding position presented when the placement was announced, rather than the cost of completing a restart.

Resource Estimate and Exploration Priorities

Cerro Bayo hosts an indicated and inferred mineral resource estimate of 136 million ounces of silver equivalent, including 60 million ounces classified as indicated. The company’s project information reports 20.0 million tonnes grading 211 g/t silver equivalent as at 30 June 2026. The resource encompasses underground and open-pit mineralisation; it is not an ore reserve or a guarantee of economically recoverable metal.

Andean Silver Limited (ASX:ASL) has outlined continued drilling across established deposits and additional targets, alongside infill work designed to inform technical studies. The company has also identified geotechnical and metallurgical work as part of its restart planning. Exploration results may change the estimated size or classification of mineral resources, but cannot by themselves establish a mine development outcome.

Half-Year Accounts and Restart Constraints

For the six months ended 30 June 2026, Andean Silver (ASX:ASL) reported a loss after tax of A$11,563,862 and cash of A$42,704,074 at period end. Net assets were A$74,258,304. These are half-year figures: the company changed its financial year-end to 31 December and therefore the June 2026 accounts do not represent a twelve-month financial result.

Cerro Bayo is not currently producing. The timing and financial requirements of any restart depend on technical studies, permitting, infrastructure condition and subsequent project decisions. While the existing processing facilities form part of the project, their presence does not establish readiness to resume commercial production. The company has outlined mill refurbishment, underground dewatering and other early works as areas of attention.

Project Milestones and Uncertainties

Andean Silver Limited (ASX:ASL) indicated that a scoping study would follow its September funding round, with feasibility work and an initial ore reserve targeted for calendar 2027. These are company-stated milestones rather than confirmed results. Conversion of resources into reserves, project costs, permitting outcomes and operating assumptions remain material uncertainties.

The company also plans further drilling and permitting across prospective areas of the Cerro Bayo district. Its concentration in one development project makes the pace of fieldwork and studies relevant to understanding progress. The financial position needs to be considered alongside ongoing exploration expenditure and the absence of operating mine revenue.

Key Insights

The 2026 placement expanded the funding available for Cerro Bayo exploration and restart assessment, while the June half-year accounts recorded continued expenditure before production. For Andean Silver (ASX:ASL), the distinction between a reported mineral resource, a future ore reserve and an approved restart remains central. Subsequent technical work and formal project decisions will determine what further development steps are supported by the evidence.
