Eloro Resources Commences Extensive Expansion Drilling at Bolivia's Iska Iska Project

Eloro Resources Ltd. (TSX: ELO) has launched its expansion diamond drilling program at the Iska Iska Project in southern Bolivia, deploying two rigs on site with a third on the way, according to Market Screener. The program targets higher-grade Silver-Tin polymetallic mineralization — a mix of silver, tin, and other metals found together in ore.
The full program spans two phases: 35 holes totalling 18,250 metres, followed by roughly 40 more holes totalling 21,750 metres, Pembroke Observer reported. That adds up to more than 40,000 metres of drilling in total — a major expansion push for the project.
Major Drilling Group International Inc. has set up the two active diamond drill rigs on site, Hanna Herald reported. A third rig is expected to arrive within the coming months. Diamond drilling uses a rotating drill tipped with diamonds to pull up cylindrical rock samples. These samples help geologists map where the richest ore sits underground.
The drilling will focus on upgrading and expanding the known high-grade silver-tin zones at Iska Iska. Eloro wants to improve the quality and size of its mineral resource estimate — a key step before any decision to build a mine can be made, according to Brantford Expositor.
The project had faced disruptions from road blockades in the area. Those blockades have since been resolved, Owen Sound Sun Times reported. Transportation routes are now open again. Diesel fuel and other essential supplies are reaching the site without interruption — critical for keeping drill rigs running around the clock.
The reopening of supply routes came at a key moment. With two rigs already spinning and a third rig mobilizing, a steady fuel supply is essential. Any future blockades could slow the program and push back the timeline for results.
Bolivia is pushing a new phase of economic reform aimed at attracting private investment and restoring growth, Pincher Creek Echo reported. The effort has drawn backing from major international lenders. The International Monetary Fund, the Inter-American Development Bank, and the Development Bank of Latin America and the Caribbean have all expressed support for Bolivia's stabilization plans.
That improved investment climate matters for Eloro. Foreign mining companies need stable governments and open roads to operate. A Bolivia that is actively courting outside capital and stabilizing its economy reduces the political risk of running a large drilling program — and eventually, a mine.
Silver and tin are both in high demand. Tin is a key material in electronics and solder. Silver is used in solar panels, batteries, and electronics. A project that holds both metals in high-grade ore is rare. Iska Iska has shown strong grades in earlier drilling, which is why Eloro is now spending tens of millions to expand the resource, according to Pembroke Observer.
With Phase 1 alone covering 18,250 metres across 35 holes, results should begin trickling in over the coming months. Each batch of drill results will either grow the known resource or help Eloro tighten up the grade estimates — both outcomes that move the project closer to a feasibility study.
