Montezuma Mining reports positive manganese metallurgical results from Butcherbird, WA


Montezuma Mining Company (ASX: MZM) recently completed metallurgical drilling and testing at its flagship Butcherbird manganese project in Western Australia.

Previous test work had indicated that a substantial proportion of the gangue matrix could be rendered to slime by moderate energy input scrubbing.

Low cost processing options have been confirmed with low deleterious element contamination.

Simple crushing, screening and scrubbing has the potential to deliver a 33.8% manganese lump product at >31.5mm.

Eight manganese deposits have been delineated within Butcherbird with a total inferred resource (JORC 2004) inventory of 119 million tonnes at 11.6% manganese, and an additional 55.9 million tonnes at 9.3% manganese.

The Butcherbird occurrence is unlike other manganese resources as its composed of manganiferous mineral bands or lenses in a matrix of weathered shales.

The project also hosts a number of copper sulphide targets.

Montezuma is capped at around $8.5 million, with $5 million in cash, and sizeable equity positions in Buxton Resources (ASX:BUX), Resource and Investment (ASX:RNI), Lithex Resources (ASX:LTX) and Exterra Resources (ASX:EXC).
