Giyani announces first indicated mineral resources to K. Hill


Canadian exploration company Giyani Metals has announced an updated Mineral Resource Estimate (MRE) for its K. Hill project in Botswana as part of the project’s feasibility study.

Infill drilling resulted in the conversion of approximately 95% of K. Hill’s current Inferred Mineral Resource to the Indicated Mineral Resource category and a 25% increase in total manganese metal contained.

Indicated mineral resources for the main K. Hill mineralized zone are reported to be 1.6 million tonnes at an average grade of 22% manganese oxide, which is equivalent to approximately 400,000 t of manganese metal contained.

Inferred mineral resources, including the newly discovered mineralized horizon known as the B horizon, are reported to be 1.4 million tonnes at an average grade of 13.9% manganese oxide, equivalent to approximately 200,000 t of metal contained.

The total metal content will be equivalent to approximately 1.7 million tonnes of high purity manganese sulfate monohydrate (HPMSM).

B-horizon samples are currently undergoing detailed mineralogical and hydrometallurgical testing and may facilitate the potential upgrade of the Inferred Mineral Resource category to those indicated.

Following the completion of the reverse circulation infill drilling program, SRK Consulting compiled an updated MRE for K. Hill.

The ERM includes results from the main mineralized zone of the K. Hill project and the new B horizon only.

Mineral resources have not yet been estimated or reported for the southern extension of K. Hill as previously announced in August.

The MRE was limited to all graded material entering an optimized pit shell representing a long term price for HPMSM of $ 1,588 / t, based on 2020 market data.

The hull also used various technical and economic parameters, derived from ongoing technical studies for K. Hill.

In addition, the MRE is reported above a cut-off content of 7.3% manganese oxide.

This represents material that SRK considers to have a reasonable prospect of eventual economic extraction.

SRK notes that pit optimization and selected pit are relatively insensitive to product price changes above an HPMSM price of around $ 1,000 / t.
