Orosur Mining (LSE:OMI) has released unaudited results for the second quarter ended 30 November 2025, outlining continued operational progress across its Colombian and Argentine gold assets alongside a materially improved cash position following a successful fundraise.
Operational and financial highlights
In Colombia, the company continued infill drilling at the Pepas gold prospect as it works toward delivering an updated NI 43-101–compliant mineral resource estimate. At the nearby El Cedro prospect, soil geochemistry results returned encouraging signatures consistent with a large, zoned gold-bearing porphyry system, with exploration also identifying a second porphyry-style target along the same structural trend. Together, these results support the broader potential of the Anzá project area.
In Argentina, Orosur earned a 51% interest in Deseado Dorado S.A.S., which holds the El Pantano licences in Santa Cruz province. The company has now advanced into the second stage of its joint venture, with a 3,000-metre drilling programme currently under way. Elsewhere in the portfolio, Orosur has made a strategic decision to withdraw from its Nigerian lithium project, which had been fully impaired, allowing management to focus capital and effort on core gold assets.
Financially, the quarter was marked by an oversubscribed C$20 million equity placing, which lifted cash balances to US$16.3 million at period end. The company reported a net loss of US$4.6 million, driven largely by non-cash factors including warrant revaluation, as well as higher exploration spend and share-based payment expenses. The strengthened balance sheet provides increased flexibility to advance exploration programmes across its priority projects.
