Larvotto Resources (ASX:LRV) has begun gravity gold and flotation testwork on underground mineralisation at its wholly owned, newly acquired Hillgrove gold-antimony Project in New South Wales.
The $14.53 million market capitalisation company says this follows posting consistent ‘high-grade’ gold and antimony in channel samples gathered from underground development stope samples.
Auger results also demonstrate consistent grades up to 1.3 grams per tonne Au, with the highest values exceeding 2g/t Au and 2% Sb from 1.5m historical tailings dam.
Tailings size and liberation testwork is also underway alongside TIMA mineralogy on unbdergorund stope samples, as well as gold and antimony concentrate samples.
Managing Director Ron Heeks says: “We commenced metallurgical test work at Hillgrove following the completion of auger drilling of the TSF1 and collection of several tonnes of representative underground samples from the development-ready zones of the Metz mining area. Channel samples from the 4 collection channels including values as high as 63g/t Au and 30% Sb highlight the high-grade nature of Hillgrove’s gold and antimony mineralisation at Hillgrove.
The historical tailings dam samples are amazingly consistent across the 1.5Mt of material contained within the dam, with gold grades higher than expected and consistently above the average grade of many operating open pit mines. Previously, most of the processing focus was on antimony rather than gold, resulting in a considerable amount of gold deposited in the tailings dam.
These samples will be subject to a detailed metallurgical study and TIMA mineralogy to determine the potential extraction rate in the case of the tails and optimal processing route for the underground mineralisation. We look forward to updating shareholders with the metallurgical results as test work progresses.”
Larvotto Resources is actively advancing its portfolio of in-demand minerals projects including the 1.4 million ounce gold equivalent Hillgrove Project in New South Wales.
Other projects include the ‘large’ Mt Isa copper, gold, and cobalt project adjacent to Mt Isa townsite in Queensland, the Eyre multi-metals and lithium project about 30km east of Norseman in Western Australia, and a gold exploration project at Ohakuri in New Zealand’s North Island.
