Oroco Reports Select Surface Sample of 7.57% Copper and Completion of Drone Magnetic Survey at Vainilla

Oroco Resource Corp. released preliminary exploration results from its Vainilla Project in northern Sinaloa, Mexico. Selective rock-chip sampling at the El Platano prospect returned a high-grade intercept of 7.57% copper within a breccia pipe. The company completed a high-resolution drone magnetometry survey covering approximately 3,114 hectares, identifying structural and intrusive frameworks consistent with porphyry and skarn systems.

Three principal areas of interest were identified with magnetic characteristics supporting further exploration. Drilling permit applications have been initiated for Vainilla. Management emphasized that the primary focus remains the Santo Tomas project, with Vainilla serving as a complementary exploration track. The 7.57% copper sample is explicitly noted as not representative of overall grade or continuity, and higher-grade values rely on laboratory standards.

Oroco Resource Corp. (OCO) released results from incremental, expected exploration activity on its secondary Vainilla property, rather than its flagship Santo Tomas project. The company reported a high-grade surface sample, which it characterized as preliminary and non-representative. This finding does not alter the timeline or economics of the Santo Tomas Pre-Feasibility Study.

A drone survey was conducted as a logical next step for target generation, though follow-up drilling is required to validate the results. The financial and operational impact of the release is neutral to marginally positive for sentiment, but does not constitute a material shift in the company's valuation drivers. Consistent with historical Phase 2 drilling updates at Santo Tomas, this news reflects standard exploration progression rather than a fundamental change in project status.

Oroco Resource Corp. is a pre-revenue junior explorer focused on the Santo Tomas porphyry copper project in Sinaloa, Mexico. The company holds an 87% net interest in the 1,173-hectare core concessions and an 80% interest in surrounding concessions.

The August 2024 Preliminary Economic Assessment (PEA) outlines a staged open-pit operation ramping from 60,000 t/d to 120,000 t/d over a 22.6-year mine life. PEA metrics include an after-tax NPV(8%) of US$1.48 billion, an after-tax IRR of 22.2%, and initial CAPEX of US$1.103 billion.

The mineral resource consists of 540.6 Mt Indicated and 530.3 Mt Inferred at 0.33% Cu and 0.31% Cu, respectively. The project is designated for fast-track permitting under Plan Sinaloa and Plan México.
