Shares of Odessa Minerals Limited (ASX:ODE) fell 11.77% to $0.015 during the trading session on 20 October 2026. Separately, on 19 October 2026, the company announced that it had staked a landholding known as the SC West Project in the San Cristóbal Mining district of south-western Bolivia. The share price move and the announcement occurred on different dates and are not linked in this article.

About Odessa Minerals Limited

Odessa Minerals is an ASX-listed explorer. In the announcement, the company says it continues to assess project opportunities and describes itself as well-funded, although it does not state a cash balance. The SC West Project is a new addition to its portfolio.

Landholding details

SC West comprises 1,153 concession squares, each of about 25 hectares, totalling approximately 28,825 hectares or 288 square kilometres. It lies in the San Agustín area of south-western Bolivia. The company says the ground was acquired opportunistically after a review of open opportunities and a regional geology review and ground truthing by consultants in Bolivia.

Initial work identified hydrothermal activity and the potential for a mineralised system, and the company says local communities have expressed support for its involvement.

Geological setting and the San Cristóbal mine

The concession lies within a volcanic and volcano-sedimentary sequence, including ignimbrites, tuffs, andesitic to rhyolitic domes, volcanic breccias and intrusive bodies. Alteration includes silicification, oxidation, argillic and propylitic alteration, quartz veining, stockwork development and brecciation.

SC West is located near the San Cristóbal silver-zinc-lead mine, which the announcement says produced about 17.6 million ounces of silver, 184,000 tonnes of zinc and 50,000 tonnes of lead in 2025. The company describes SC West as prospective for similar mineralisation, but no resource or drilling has been reported there.

Exploration approach

The company plans systematic exploration to refine priority areas for follow-up drilling. First-pass soil and rock chip samples have already been collected, with portable XRF screening used to prioritise samples for laboratory assay. The samples are at the laboratory, and results are expected in the coming months.

Sector backdrop

Bolivia’s south-west contains a long-established silver, zinc and lead mining province. Explorers working in the country need to deal with its mining laws, concession systems, community relations and infrastructure constraints, which differ from those in Australia.

Silver and zinc are used in industrial applications, and early-stage concession packages typically need several rounds of sampling and drilling before any resource can be defined.

Risks shareholders should weigh

The land has been staked, and the announcement does not describe the legal status of the concessions or any approvals still required. No assay results, drilling or resource estimates exist yet for SC West, and proximity to a large mine does not establish that similar mineralisation is present.

Operating in Bolivia involves jurisdictional, regulatory and community-related risks. The cost of the exploration programs will need to be funded, and the company has not stated a budget. At $0.015, the 11.77% fall on 20 October 2026 shows how a low share price can produce large percentage moves.

What’s next

Laboratory results from the first-pass soil and rock chip sampling are expected in the coming months. These are intended to refine exploration programs and to help identify priority areas for follow-up drilling.
