Freehill Mining Limited has announced a significant technical achievement at its Yerbas Buenas magnetite mine in Chile. The company completed magnetic test work on a 400kg bulk sample produced at the mine, resulting in a concentrate grading 65.75% iron. The sample, derived from material crushed to 6 millimeters, underwent several processing stages. Initially, a head grade sample of 43.84% iron was obtained, followed by a classification process using an 18-inch mesh that identified a fine grade sample averaging 48.68% iron. After processing through a magnetic drum at a speed of 35 HZ and further treatment at 45 HZ, the concentrate produced reached the target grade. The results came with an independent certification by San Lorenzo Chemical Laboratory in Vallenar, Chile, underscoring the reliability of the outcome. The technical process outlined by Freehill included multiple steps to optimize the recovery of high-grade iron from the ore. The use of varying drum speeds and the careful classification of ore samples indicate a robust approach to achieving a premium concentrate, which is seen as marketable to a wide range of customers. The company has signalled further test work, with plans to assess material crushed to 3 and 5 millimeters to evaluate whether even higher iron grades can be produced. This detailed evaluation supports the company’s broader strategy of advancing mine planning and reviewing permitting scenarios, while defining the capital expenditure necessary to recommence magnetite mining from the historical pit. Sentiment based on the news is mixed. On the bullish side, the demonstration of a high-grade concentrate from the Yerbas Buenas mine may attract potential off-takers and trading houses, positioning Freehill Mining Limited to unlock additional revenue with relatively low capital outlay. Moreover, progress in the aggregates business and the ongoing development of new supply agreements further bolster the company’s near-term prospects. Conversely, on the bearish side, there remain uncertainties around the necessary mine planning, capital expenditure requirements, and potential permitting challenges. These factors could introduce delays or additional costs, which may temper short-term investor enthusiasm. Overall, while the technical results inspire optimism for future revenue streams, the execution of subsequent plans and management of regulatory hurdles will be crucial for sustaining growth.
