Our Approach
On Projects
Technical Development of Evaluated Assets
Orosphere and its engineering partners oversee the full technical development lifecycle of each project we activate. From mine design to metallurgical processing and closure planning, we build projects that are technically sound, economically viable, and socially aligned.
01
Mining
We design mining strategies that reflect both the geological realities of the asset and the business model that underpins it balancing efficiency, scalability, and cost.
02
Extractive Metallurgy
Processing facilities are tailored to the mineral profile and economic targets of each project. Maximizing recovery while minimizing capital expenditure is the foundation of a fundable operation.
03
Environmental Remediation
Closure and long-term land use are planned from the outset. All projects are evaluated for their post-production potential ensuring ESG alignment, regional benefit, and regulatory confidence from day one.

Our Projects
Guatemala
El Tambor is a high grade gold asset fully owned that is being positioned as the country's largest producing gold mine. Preliminary production provided a mill head grade of 10 grams/ton with a recovery of above 80 percent. This asset looks to contain 4 million ounces or more essentially on the surface. We anticipate with more evaluation this project can become a world class resource.
Mexico
El Oro is a tailings remediation project outside of Mexico City. This asset is clearly defined by the previous owner Xali Gold. The tailings are estimated to contain 1.27 million tonnes at a grade of 2.94 grams per tonne (“gpt”) gold and 75.12 gpt silver (3.85 gpt gold equivalent) containing 119,900 ounces (“oz”) of gold and 3,061,200 oz of silver. Recent sampling and metallurgical testing has confirmed the recoverability of those ounces and is now being integrated into the processing design.
USA
Doby George is a well defined heap leachable asset in Nevada, one of the best mining jurisdictions. We are planning for 2026 and 2027 to finalize permitting with construction commencing in January of 2028. We will anticipate a capital cost of 144m and between 2029-2032 after taxes and royalties the project will generate $123m/yr for the investors and Orosphere.
