Infill drilling has resulted in the conversion of about 95% of the current inferred mineral resources for K.Hill into the indicated mineral resources category and a 25% increase in total contained manganese metal.
Indicated mineral resources for K.Hill’s main mineralised zone are reported as 1.6-million tonnes at an average grade of 22% manganese oxide, equivalent to about 400 000 t of contained manganese metal.
Inferred mineral resources, including the newly discovered mineralised horizon, known as the B Horizon, are reported as 1.4-million tonnes at an average grade of 13.9% manganese oxide, equivalent to about 200 000 t contained metal.
Total contained metal will equate to about 1.7-million tonnes of high-purity manganese sulphate monohydrate (HPMSM).
Samples from the B Horizon are currently undergoing detailed mineralogy and hydrometallurgical testwork and may facilitate potential upgrade from the inferred to indicated mineral resources category.
The MRE includes results from the main K.Hill project mineralised zone and the new B Horizon only.
Mineral resources have not yet been estimated or reported for the southerly extension of K.Hill as previously...
