Legacy Minerals Ltd (ASX:LGM) has returned high-grade silver, gold, zinc and lead from reverse circulation (RC) drilling at Mt Felsted Prospect within the Bauloora Project in central New South Wales.
Mt Felstead, which is 10 kilometres northwest of Cootamundra, is the first of several high-priority target areas to be drill tested at Bauloora with the new assay results highlighting the high-grade nature and strike extent of the deposit including:
- 3 metres at 1.65 g/t gold, 152.8 g/t silver, 0.35% copper and 6.9% lead+zinc from 149 metres, including 1-metre at 4.75 g/t gold, 442 g/t silver, 0.99% copper and 19.47% lead+zinc from 149 metres;
- 5 metres at 0.99 g/t gold, 17.9 g/t silver, 0.27% copper and 2.76% lead+zinc from 97 metres, including 1-metre at 3.03 g/t gold, 63.4 g/t silver, 0.58% copper and 8.12% lead+zinc from 99 metres; and
- 9 metres at 0.88% lead+zinc from 162 metres, including 1-metre at 3% lead+zinc from 163 metres.
Legacy engaged ALS to conduct metallurgical test-work on three drill holes from the Mt Felstead campaign with results expected in the coming weeks.
The company also completed downhole electromagnetics (DHEM) on three holes at the prospect and is interpreting the results.
“High-grade nature”
Legacy managing director Christopher Byrne said: “The Mt Felstead Prospect continues to showcase its high-grade nature.
"Like our initial drilling assays, we are exceedingly pleased with the results showing gold-silver and base metal mineralisation is present and open at depth and along strike.
“The Mt Felstead prospect is one of five key prospects at our Bauloora epithermal project in which where we are aggressively exploring an 8-square-kilometre anomalous gold zone with plans to continue drilling in the near future.”
Drill summary
RC drilling to date has focused on the Mt Felstead Prospect where breccia and vein hosted massive and semi-massive sulphides have been intersected.
The drill assays and logging have defined a mineralised breccia dipping about 85 degrees to the west, with parallel mineralised veins striking north-south.
Mineralisation has been defined in drilling to 170 metres depth along a 450 metres strike length, with mineralisation open down dip and along strike, where rock chip sampling has defined outcropping mineralisation at the surface for 670 metres.
The main zone of mineralisation intersected at Mt Felstead to date occurs as a steeply dipping lenticular zone, or ore shoot, developed in a fault breccia. Sphalerite, galena, chalcopyrite, tetrahedrite and gold are hosts in quartz, chalcedony, calcite, chlorite, fluorite and lesser barite-bearing veins.
Metallurgical testing
Legacy Minerals has engaged ALS to conduct metallurgical test-work on selected samples representative of the mineralisation intersected to date at the Mt Felstead Prospect.
The objectives of the metallurgical testing are to determine the best means of beneficiating the mineralised material and also determine the most commercial means of recovering the contained metals values.
Results from the metallurgical testing are expected in the coming weeks.
Forward plan
Beyond the metallurgical tests and DHEM interpretation at Mt Felstead, Legacy is also planning a large-scale soil program across the tenement.
The goal of the program will be to increase the company’s confidence in the drill targets planned for testing later in the year.
