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.

Potential Mining Advantages

The Project is located in a tropical environment characterized by the development of a generally thick weathering profile. As a result, near-surface material is commonly strongly weathered and friable, which may facilitate excavation without the need for drilling and blasting in the highly weathered zones.

In addition, mineralization occurs at or near surface and is developed within relatively mountainous terrain. These characteristics may potentially result in relatively low waste-to-ore stripping ratios during open-pit mining. However, the actual mining conditions and stripping ratios will need to be established through future mine planning and technical studies.

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.
