Structurally Controlled Mineralization and Deep Subsurface Continuity

Graphite mineralization at the Macarani Graphite Project is hosted in metasedimentary rocks of the Macaúbas Group, primarily within graphitic and mica schists. The deposit exhibits a dominant NW-SE structural control with a gentle NE dip, traced continuously for over 2 kilometers without significant lateral discontinuity.

Corpo A: The OPEX Advantage (Free-Digging Target) Recent technical evaluations have prioritized the Corpo A target. The mineralized material in this sector is highly friable, presenting a distinct operational advantage: it allows for "free-digging" (explosive-free extraction) during the early years of operation. This dynamic has the potential to significantly reduce initial operating costs (OPEX) and accelerate early cash flow profiles.

Geophysics: Validating Deep Continuity To trace the graphite mineralization below the limits of shallow surface sampling, Geopportunity executed a comprehensive terrestrial geophysical program. A total of 23 sections were surveyed using the electrical resistivity method (Wenner array). The surveys delineated continuous low-resistivity (conductive) anomalies that perfectly correlate with the mapped graphite outcrops at the surface. Crucially, the geophysical sections confirm that the mineralized zones extend deeply into the subsurface, forming the precise targets for our upcoming diamond drilling campaign.

Rigorous QA/QC To ensure M&A-ready data integrity, all recent analytical work was executed by SGS Geosol. The program utilized strict industry-standard QA/QC protocols, including blanks, duplicates, and certified reference materials (OREAS 722, 723, and 724). QA/QC results support the reliability of the analytical data.
