ChemX’s upcoming maiden resource estimate for its Jamieson Tank manganese project in South Australia is looking positive if the first stage assays from drilling are any indication.

Assays from the first 39 of the 94 holes drilled during the 2023 program returned results such as 6m grading 18.5% manganese from a down-hole depth of 9m (JTRC218), 18m at 10.1% manganese from 10m (JTRC234) and 12m at 11.9% manganese from 13m (JTRC213).

The discovery of significant near-surface manganese intercepts not only provides ChemX Materials (ASX:CMX) with confidence about the resource estimate in June 2023, it is also encouraging in light of previous metallurgical testwork carried out last year which indicated the ore is highly amenable to upgrading via beneficiation.

“The results which will go towards the maiden resource estimation, which will be used to support the potential to achieve a beneficiation plant feed of manganese, ultimately destined for the global battery grade manganese market,” chief executive officer Mark Tory said.

“Noting the shallow depths for much of the mineralised intercepts gives confidence to swift accessibility on potential future mining endeavours.”

Manganese is becoming increasingly critical given the growing popularity of manganese-rich battery chemistries such as lithium iron phosphate (LFP).

Jamieson Tank project

Current exploration at Jamieson Tank in South Australia’s Eyre Peninsula is designed to test the exploration target – which ranges from 21Mt to 35Mt grading 7.5% to 10.1% manganese – and establish a robust geological control of the manganese mineralisation.

Initial testwork completed last year also succeeded in producing manganese sulphate crystals with 99.7% purity.

The project is surrounded by the necessary infrastructure, services and people necessary for a successful project.

These include a number of renewable energy sources, rail lines, ports and roads.

Additionally, it is just one of five prospects within the greater project area.
