Kalamazoo Resources boosts Ashburton potential with positive metallurgical test work

Kalamazoo Resources ASX KZR Ashburton positive metallurgical test work gold Mt Olympus
Kalamazoo executive director Paul Adams says test work indicates Mt Olympus ore is amenable to a simple, easily operable, and well understood process flowsheet.

Kalamazoo Resources (ASX: KZR) has received positive metallurgical results on ore from the Mt Olympus deposit within its 1.65 million ounce Ashburton gold project.

The company completed stage two metallurgical test work on Mt Olympus, which is a sulphide deposit.

Test work involved a variety and gravity and re-grinding processes, which increased the concentrate grade on the composite four sample from 39 grams per tonne gold to 45g/t gold, with improved silica rejection.

The test work indicates a simple crush, grind, rougher flotation, multi-stage reclean flotation circuit would generate a saleable concentrate.

According to Kalamazoo, this provides the simplest, least capital intensive and most easily operable process route for the deposit’s mineralisation.

Kalamazoo executive director Paul Adams said the company was “extremely pleased” with the test work results – particularly when combined with the initial test work results.

“This work will now be used in our planned project development scoping study, which is scheduled to commence shortly.”

“We consider that a simple, easily operable, well understood process flowsheet is the preferred option for the future development of the sulphide resources at our Ashburton gold project,” he explained.

Advancing Ashburton gold project

Mt Olympus has an indicated and inferred mineral resource of 15.12 million tonnes at 2.2g/t gold for 1.08Moz.

It is the largest contributor to the Ashburton global resource of 1.65Moz.

Located in the southern edge of the Pilbara craton in Western Australia, Ashburton is amid renowned gold discoveries in the region including De Grey Mining’s (ASX: DEG) 9Moz Mallina project, Calidus Resources’ (ASX: CAI) 1.5Moz Warrawoona project, and Novo Resources’ (TSX: NVO) Beatons Creek asset.

Following this positive test work, Kalamazoo will undertake lock cycle testing to estimate the overall flotation recovery.

The company may also complete cyanide leach of flotation tails to evaluate total recoverable gold.

For the ongoing test work, Kalamazoo will also gather more diamond core composite samples.
