The company says results from the Northern and Central zone samples vary due to their different mineralogy.
Microphotographs of thin sections show the Central zone graphite also has significant haematite (iron oxide) alteration, attributed to a nearby granitic intrusive on its northern side. The intrusive area is believed to have contributed to a higher degree of “graphitisation” of the Central ore by the heat and fluids.
Sarytogan plans to continue its variability testing. Meanwhile, 700 kilograms of milled Central zone graphite is being prepared for flotation to generate samples for customer testing.
The company has two drill rigs engaged in reserves definition drilling on site to ensure its definitive feasibility study remains on track for completion by mid-2026.
A JORC 2012-compliant indicated and inferred mineral resource was delivered in 2023 by AMC Consultants totalling 229 million tonnes at a grade of 28.9 per cent TGC.
In 2024, the company delivered a JORC 2012-compliant estimated ore reserve of 8.6 million dry tonnes at a grade of 30.0 per cent TGC for a total contained TGC mass in concentrate of 2.16Mt.
