Eloro Resources: Mine Over Matter

Iska Iska is unique in hosting two distinct mineralised systems within a single contiguous footprint: a silver-rich polymetallic domain containing zinc and lead, and a tin-rich domain featuring high-grade cassiterite. The polymetallic domain has already delivered a 560Mt inferred resource, while the tin domain contributes an additional 110Mt, making Eloro one of the few juniors globally with exposure to two scale-ready deposits.


These systems are geologically linked but distinct enough to offer operational flexibility. This dual-deposit structure allows Eloro to target different processing routes, offtake partners, and commodity markets, diversifying both its development options and future revenue streams. Importantly, silver is not only the dominant contributor to the polymetallic resource but also offers strong potential for early-stage production due to its near-surface distribution. As further drilling continues to expand mineralisation at depth and along strike, the company may be sitting on one of the largest untapped systems in the prolific Bolivian Tin Belt.

Tin is emerging as one of the world’s most critical minerals, driven by demand from semiconductors, EV batteries, AI infrastructure, and solar technology. Yet, its supply chain is fragile and dominated by politically sensitive jurisdictions like China, Indonesia, and Myanmar. This mismatch has led to increasing attention from governments and manufacturers looking to secure reliable sources of tin. Eloro’s Iska Iska project stands out for its scale, Western alignment, and geological potential to produce high-grade tin and silver concentrate. With its Tin Domain ranking among the ten largest undeveloped tin deposits globally, Eloro offers investors one of the few large-scale ways to gain exposure to a strategic metal that is entering a structural supply deficit.

Alongside this, silver, with its dominant role in the polymetallic domain, provides additional strategic leverage, supported by surging industrial demand across solar, electronics, and clean energy sectors. Tin currently comprises the largest share of silver-equivalent value in the deposit, but silver itself remains a core economic driver and a compelling asset in its own right.

Rather than waiting for a full-scale feasibility study, Eloro is fast-tracking development through a proposed pilot plant. This initiative offers a low-capex, high-impact way to validate metallurgy, processing flowsheets, and concentrate recoveries in real-world conditions. Designed to operate at 300tpd (from a 500tpd ROM feed), the pilot is expected to cost US$20-25M and take 12-16 months to build. Early results from metallurgical work indicate promising gravity separation potential for the tin and robust silver recoveries.


The pilot project is not only a technical de-risking milestone, but also a potential funding catalyst, helping to attract strategic partners, offtakers, or financiers ahead of a commercial build-out. It also enables Eloro to test and optimise processing approaches tailored to the complex mineralogy across its two domains. Importantly, the project is supported by a mining-permitted jurisdiction with excellent infrastructure access, strong local relationships, and, following a recent shift in government, an increasingly pro-investment stance and growing diplomatic alignment with the United States.

• Pilot plant announcement: A formal decision to proceed with the pilot plant, including financing terms and construction timeline, would signal de-risking and accelerate momentum toward near-term production.

• High-grade drill results: Continued strong intercepts from tin and silver-rich zones, particularly step-out holes or deeper hits, would strengthen the case for resource expansion and increase investor confidence in Iska Iska's upside.

• PEA release: The Preliminary Economic Assessment will quantify project economics for the first time, providing key metrics like NPV, IRR, capex, and payback that could validate the project's value proposition to institutions and strategic investors.

• Strategic partnership or offtake deal: Securing a tin or silver offtake agreement, or a JV partner for development, would provide external validation and help de-risk funding, especially in a geopolitically attractive jurisdiction like Bolivia.

• Feasibility study and project financing: Advancing from PEA to full feasibility will require further metallurgical testing and pilot-scale validation. Completion of this study, along with any debt or equity financing for commercial development, would mark a key inflection point.

• Commencement of construction: Breaking ground on commercial infrastructure, such as a processing plant or underground access, would signify a major step toward production and materially de-risk Eloro's long-term pathway.

The economic potential of Iska Iska depends on effective extraction of tin and silver. Tin, in particular, is technically complex to process. While early testing has shown about 50% recovery, this must improve to support a robust economic case. Gravity separation shows promise, but pilot-scale proof will be essential. If recovery rates remain low, it could limit the project's scope and shift focus away from tin, reducing Eloro's strategic relevance.

Even with a phased approach, Iska Iska's commercial development will be capital intensive. Eloro's market cap (~C$150M) suggests it will need substantial outside funding. While the clean balance sheet is an advantage, accessing large-scale capital in volatile markets may be challenging. Any delays, dilution, or changes in macro conditions could impact investor returns or timelines.

Bolivia is historically mining-friendly, but political shifts and regulatory uncertainty remain. Government classification of tin as strategic could introduce new ownership or export restrictions. Although Eloro has strong local support and relationships, sovereign risk remains a factor as the project moves closer to development.
