Australia Minerals & Mining Group determines coarse grind suitable for WA magnetite 

(MENAFN - ProactiveInvestors - Australia) Australia Minerals & Mining Group (ASX: AKA) has received the results of recent metallurgical test work at its Bencubbin Magnetite Project which indicate a very coarse liberation of magnetite at a grind size of 150 microns.

The average iron concentrate was above 70% with an average mass recovery of 38.6% with a 'coarser' grind size of 150 microns.

Importantly, these results allow for much lower operating costs for this style of deposit.

A coarser grind size than has previously been reported in the Mid-West area and that of Western Australia has the benefit of lower energy input due to lower crushing costs in a potential processing plant.

Additionally, concentrate impurities contained low phosphorus, low silica, low alumina and low sulphur.

This further metallurgical test work was conducted to determine the optimum grind size and metallurgical characteristics of the Bencubbin magnetite body.

The Bencubbin tenement is bisected by rail and is strategically located about 220 kilometres from Perth. The geological structure has a strike length of 14 kilometres.


Stage two drilling

Australia Minerals & Mining Group now plans to evaluate a follow-up stage two reverse circulation drill program or advance potential joint venture participation over the length of the Bencubbin project.

The stage two program is scheduled to begin in 2013.

Importantly, Australia Minerals & Mining Group remains well funded to advance exploration with around A4.2 million cash at the end of the September 2012 quarter.
