Montezuma: Battery Grade Electrolytic Manganese Dioxide Potential at Butcherbird

Montezuma Mining Company Ltd (ASX:MZM) (“Montezuma” or “Company”) is pleased to announce that the Commonwealth Scientific and Industrial Research Organisation (“CSIRO”) Process Science and Technology Group has successfully completed the first phase of the research and development studies into the production of high purity Electrolytic Manganese Dioxide from manganese ores sourced from the Company’s 100% owned, infrastructure endowed Butcherbird Project in Western Australia.
As quoted in the press release:

• First phase of leach tests to produce Electrolytic Manganese Dioxide  (“EMD”) from the Butcherbird Manganese Deposit ore a success.

• Initial leaching results achieve >95% Mn extraction with rapid leach kinetics and impressive leach selectivity before any flowsheet optimisation.

• The test work confirms the potential for on site hydrometallurgical options to add significant value to the Butcherbird Project.

• Butcherbird is Australia’s largest onshore manganese resource with in situ resources of over 170 million tonnes of manganiferous ore.

• EMD is an important technology metal with over 90% of global consumption used in battery manufacturing.

• Lithium-Ion battery 1 cathodes contain up to 60% manganese, which is ~5 times the contained value and ~15 times the amount of contained lithium.
