METALLURGY & TECHNICAL DATA

Preliminary Bench-Scale Metallurgical Testing by SGS Geosol

Preliminary metallurgical characterization has been conducted for the Macarani Graphite Project. In September 2024, SGS Geosol received ten graphite mineralization samples collected from the Project, totaling approximately 256.1 kg.

The samples were blended to produce a composite sample for technological characterization and preliminary bench-scale flotation testing. Following preparation, the composite material was homogenized and divided into 1 kg subsamples for laboratory testwork.

The open-circuit flotation process, utilizing a scrubber and seven cleaner stages, yielded the following preliminary bench-scale results:

Feed Grade: 5.20% Cg
Concentrate Grade: 81.5% Cg
Metallurgical Recovery: 72.5%
Mass Recovery: 4.62%

Technical Report & Mineral Resource

A new technical report prepared by Dr. Volodymyr Myadzel, PhD, MAIG, consolidates the Macarani Graphite Project's geological database, geological interpretation, 3D modelling, exploration results and mineral resource assessment.

The report has been structured using the principles and technical framework of NI 43-101 and Form 43-101F1 as reference.

The report presents an Inferred Mineral Resource of approximately 14.34 million tonnes at an average grade of 3.81% Cg for Body B. Additional exploration potential has been identified separately from the Mineral Resource. Macarani remains an exploration-stage graphite project.

Geophysical Survey and Structural Interpretation of the Macarani Graphite Deposit

The geophysical survey encompassed 23 survey lines, each averaging 320 meters in length, facilitating the acquisition of a high-resolution dataset for detailed structural interpretation and subsurface characterization.
