Mt Malcom Mines produces gold doré from Golden Crown bulk sampling material
Mon Oct 21 2024
Mt Malcolm Mines’ bulk sampling program at the Golden Crown prospect has successfully produced inaugural gold doré bars weighing a total of 13.85oz from processing of 167t of mineralised material.
The bulk sampling material was processed at a nearby gravity facility.
Mt Malcolm Mines (ASX:M2M) noted that visible gold was observed in the rock chip samples collected from the zones of mineralisation, with 11 of the 30 samples returning assays of over 5g/t gold as well as a top result of 458.39g/t gold.
“The inaugural gold doré bar represents a significant achievement in the gravity processing at Golden Crown, and we are thrilled to have reached this key milestone,” managing director Trevor Dixon said.
“These promising results strengthen our confidence in the prospect's economic potential, and we are excited to proceed with further work to unlock its full value.”
Bulk sampling
The bulk sampling will test up to 8000t of ore within a well-defined, 50m long and 15m wide mineralised corridor at Golden Crown to explore and evaluate the prospect’s gold mining potential.
Golden Crown sits within the Malcolm Dam prospect area – a historical gold producer that yielded more than 1720oz at an average grade of 29g/t gold but saw relatively minor exploration – and is the first of several prospects within the 275km2 Malcolm project in WA’s prolific Goldfields region to undergo detailed exploration.
Bulk sampling excavation has reached a depth of about 9m with efforts ongoing to excavate and extract deeper mineralised material which is relatively of higher grade as per grade control drilling.
M2M says it has submitted the head grade and tailings samples from the first 167t parcel to Intertek for fire assay analysis with results expected within a month.
The head grade assays will aid in determining gravity gold recovery percentage, while the tailings (the material remaining after initial gravity processing) assays are expected to indicate its inherent potential economic value.
Another two batches totalling 78t are under processing while bulk sampling is continuing.
