Freehill Mining Limited has achieved a promising 65.75% Fe magnetite sample from its fully owned Yerbas Buenas Mine in Chile. The strong test results pave the way for further magnetic test work and near-term plans to restart low capex magnetite mining, drawing interest from potential trading partners.

Freehill Mining Limited has announced encouraging progress from its Yerbas Buenas mine in Chile. The company recently completed magnetic test work on a 400‑kilogram bulk sample of magnetite that, after being crushed to 6 millimeters and processed through an onsite magnetic drum, produced a concentrate averaging 65.75% iron. The testing procedure involved multiple steps, including a preliminary crushing stage that yielded a coarse product with a grade of approximately 43.84% iron. Subsequent processing with magnetic separation at drum speeds of 35 Hz and 45 Hz, along with an 18‑inch mesh classification, resulted in a significant upgrade of grade, with the final concentrate clearly outperforming its rejection sample, which recorded 44.14% iron. The technical success of this trial reinforces earlier metaurgical work and provides Freehill Mining Limited with a strong foundation to advance mine planning, review various permitting scenarios, and outline the capital expenditure necessary to recommence magnetite mining operations from the historic pit. The company’s management highlighted that the material’s excellent grade and marketability will serve as a compelling signal to prospective off‑takers and trading houses. In parallel, progress at the aggregates business continues to develop, with the team mobilizing to a new site and expanding the pipeline of potential supply agreements. The news carries a bullish sentiment, as the high‑grade magnetic concentrate paves the way for near‑term revenue generation with relatively low capital requirements. Investors looking for opportunities in commodities may see the company’s strategy, which is backed by successful technical trials and a clear roadmap for scaling operations, as a positive catalyst. On the other hand, a bearish perspective might note that further test work—specifically, assessing material crushed to finer sizes of 3 and 5 millimeters—is still pending. Additionally, uncertainties remain in finalizing mine planning, securing permits, and determining the full scope of capital investment needed to restart full‑scale operations. Overall, the announcement positions Freehill Mining Limited with a promising near‑term opportunity that could deliver shareholder value amid the inherent risks of mining development.
