Eloro Resources Jumps on Bolivian Project Progress, But Year-to-Date Losses Persist

Eloro Resources jumps 15% as tin recovery improves at Iska-Iska; PEA due soon, 40,000m drilling underway, and US defense inclusion boosts outlook.

Eloro Resources saw its shares climb nearly 15% to €1.35 at the start of the trading week, as investors cheered operational advances at the company's Iska-Iska project in southwestern Bolivia. The polymetallic deposit, located in the Potosí department, hosts a significant silver-tin resource alongside zinc and lead.

The Toronto-based explorer has been refining its metallurgical processes, with recent improvements in tin recovery rates seen as a critical step toward future profitability. These efficiency gains come as the company prepares to publish its first preliminary economic assessment (PEA) in the coming months — a study that will combine technical and financial data to evaluate the project's commercial viability.

Bolivia's regulatory environment continues to support the development effort. The country’s modern mining laws and openness to international investment provide a stable backdrop for Eloro's operations, which include an option to acquire full ownership of the property.

In a separate strategic move, Eloro purchased shares in Cartier Silver Corporation during March, broadening its exposure to the precious metals sector. The company also completed a private placement worth C$17 million in the same month, bolstering its balance sheet for the next phase of exploration.

A 40,000-metre drilling program that began in February is now underway, aimed at better defining the geological structures at Iska Iska. The company released updated resource estimates at the end of April, reporting an indicated resource of 85.17 million tonnes containing approximately 110 million ounces of silver and one million tonnes of zinc.

Eloro's inclusion in the US Defense Industrial Base Consortium marks another milestone, positioning the firm as a potential supplier of critical minerals for American defence and technology supply chains.

Despite the recent rally, the stock remains under pressure on a year-to-date basis, with losses of roughly 30% since January. The shares have exhibited extreme volatility, with a fluctuation range exceeding 80%. On a 12-month view, however, the stock has gained over 130%, reflecting the speculative nature of junior mining investments tied to early-stage project catalysts.

The next quarterly financial results, due in the second quarter, will provide investors with a clearer picture of the company’s liquidity position and its ability to fund ongoing exploration and development work at Iska Iska.
