Oroco mobilized a diamond drill rig to the Santo Tomás South Zone and commenced Phase 2 drilling on Feb 24, 2026 to support resource-classification upgrades. In parallel, Oroco advances Pre-Feasibility Study programs covering hydrogeological, geotechnical and metallurgical testing to reduce technical risk and support future mine planning.
Cyborg Score Rationale
Oroco is advancing a material copper asset with a significant NPV and has completed a Preliminary Economic Assessment as of August 2024. Active Phase 2 drilling as of February 2026 demonstrates operational momentum. However, as an exploration-stage company with no revenue and ongoing capital requirements, risks remain elevated relative to established producers.
