Drilling has extended known gold mineralisation at Kalamazoo Resources’ (ASX: KZR) 1.65 million ounce Ashburton project in Western Australia’s Pilbara.
The company has received assays from 47 reverse circulation holes from a phase two drilling campaign at the project, along with nine RC and one diamond hole from a phase one drilling program at the West Olympus, Peake and Zeus deposits.
Kalamazoo noted phase one drilling at West Olympus has identified two additional thick loads that remain open down plunge.
Highlight intercepts were 19m at 1.26 grams per tonne gold from 196m; 10m at 2.26g/t gold from 123m, including 2m at 4.16g/t gold from 128m; and 5m at 3.62g/t gold from 100m.
Meanwhile, phase two drilling at West Olympus had extended mineralisation 100m to the west of the deposit.
Notable results from this program were 6m at 1.32g/t gold from 23m; and 4m at 1.16g/t gold from 24m, including 1m at 3.17g/t gold.
Kalamazoo director and Ashburton project manager Paul Adams said ongoing feasibility studies were focused on open pit mining across both West Olympus and Mt Olympus deposits within the project.
West Olympus and Mt Olympus have a combined resource of 1.08Moz of contained gold.
Peake and Zeus potential
Over at the Peake deposit, drilling has identified the main gold lode runs 200m west of the current resource, which contains 399,000oz gold.
Best intercepts were 1.2m at 15.15g/t gold from 79m, 4m at 3.14g/t gold from 15m, and 1m at 11.7g/t gold.
At Zeus, which has a 72,000oz gold resource, drilling confirmed mineralisation further southwest, with highlight hits of 9m at 1.08g/t gold from 177m, and 5m at 1.69g/t gold from 118m.
Mr Adams said drilling at these deposits aimed to build new oxide gold resources.
“The drilling has delivered encouraging results, with shallow oxide gold mineralisation intercepted outside of the current resource envelopes at both the West Olympus and Peake deposits.”
“Further work is now required to investigate the potential for zones of supergene enriched gold associated with some of the shallow mineralised intercepts.”
Mr Adams said the company was “well advanced” in its exploration planning and drill targeting for brownfield and greenfield prospects at Ashburton.
As part of this, an “extensive” phase three drilling campaign is scheduled to begin at Ashburton this year.
Assays remain outstanding for the remainder of holes drilled under the phase two program at the project.
Kalamazoo is also awaiting results from surface and rock chip sampling completed at Ashburton.
