Orosur Mining is a South American focussed mineral exploration company, focused on the discovery and development of high quality precious and base metal deposits in mining-friendly jurisdictions.
The Company, a corporation existing under the laws of Yukon, is dual listed on both the TSX.V and AIM, but has no physical head office; instead boasting an experienced board and management team that are located around the world and who work together efficiently in the field and remotely via modern communication and cloud technologies.
Following the closure of its long-lived gold mining operation in Uruguay, the Company is now focussed on its balanced portfolio of high quality, advanced and earlier stage assets across the South American continent.
The Company’s flagship project at Anzá is an advanced gold project in the midst of the prolific Mid-Cauca belt that hosts most of Colombia’s major gold projects. The Anzá Project is now 100% owned by the Company following completion of a Share Purchase Agreement (“SPA”), announced 28th November 2024, whereby the Company purchased all of the shares of its previous JV partner;
Minera Monte Aguila (“MMA”), iself a 50/50 venture between the world’s two largest gold miners, Agnico Eagle Mines and Newmont Mining.m over a 12 year period.
Over 50,000m has been drilled at Anzá, identifying extensive high-grade gold mineralisation at the APTA and Pepas prospects in the centre of the project. Work programs are now focussed on advancing Pepas to a Mineral Resource Estimate (MRE) and assessing the potential of the remainder of the (largely untouched) 330km2 of licences.
The Company is also earning equity in an early-stage gold/silver project in the Patagonia region of Argentina (El Pantano). Drilling commenced in November 2025 and it is expected that the Company will move to 100% ownership of the project in early 2026.
