Galena Mining reports strong lead-silver intersections greater than 50 metres at Abra Base Metals Project

The drilling density at Abra has been improved across the shallower northern area of the deposit, which has the potential to optimise the early years of the mine plan.

Galena Mining Ltd (ASX:G1A) (FRA:GM6) has announced the third batch of assay results from the now completed 2020 drilling program at the Abra Base Metals Project. 

A total of 57 diamond drill holes (around 25 kilometres worth) were completed, with four drill-holes showing cumulative lead-silver intersections greater than 50 metres around previously reported drill-hole AB147. 

Notably, AB147 encountered 86.1 metres of combined down-hole cumulative thickness of significant intersections – and was considered to be the best high-grade lead-silver drill-hole in Abra’s history. 

Three holes extended into copper and gold mineralisation, with intersections including:

  • 3.0 metres at 2.0% copper, 2.3 g/t gold and 29 g/t silver from 401.6 metres;
  • 6.0 metres at 1.8% copper and 1.3 g/t gold from 391.8 metres; and
  • 4.9 metres at 1.0 g/t gold and 24 g/t silver from 424.2 metres.

“Confirming high-grade mineralisation”

Galena managing director Alex Molyneux said: “We continue to see the area around the previously reported ‘best hole ever’, AB147 confirming relatively shallow thick, high-grade mineralisation.

“The four holes being reported today with cumulative significant intersections greater than 50 metres are all from that area.

“I’m also pleased we finished the substantial program safely and efficiently, and I commend our Geology Team and our primary contractor DDH1 Drilling for their hard work and professionalism!”

Lead-silver intersections

This third batch of assays includes results from 18 drill holes and intersections from eight holes added to the program to expand the shallow, close to infrastructure ‘metal-rich’ zone around the previously reported high-grade lead-silver drill-hole.

The lead-silver intersections confirm wide, high-grade mineralised zones, including:

  • 32.3 metres at 13.8% lead and 34 g/t silver from 352.7 metres;
  • 22.8 metres at 7.5% lead and 24 g/t silver from 277.1 metres, and 20.1 metres at 8.9% lead and 18 g/t silver from 338.7 metres;
  • 24.3 metres at 10.9% lead and 24 g/t silver from 288.5 metres, and 9.9 metres at 18.1% lead and 31 g/t silver from 342.3 metres;
  • 16.9 metres at 9.3% lead and 36 g/t silver from 398.9 metres;
  • 17.7 metres at 8.8% lead and 30 g/t silver from 308.1 metres, and 17 metres at 8.6% lead and 15 g/t silver from 329.7 metres;
  • 16.6 metres at 9.2% lead and 25 g/t silver from 352.7 metres, and 17 metres at 6.5% lead and 10 g/t silver from 374 metres;
  • 13.1 metres at 8.7% lead and 16 g/t silver from 404 metres;
  • 15.9 metres at 7.4% lead and 14 g/t silver from 437.8 metres; and
  • 10.7 metres at 9.2% lead and 26 g/t silver from 378.8 metres.

Optimising the mine plan

Importantly, drill hole AB147 was targeting a prospective ‘metal-rich’ zone not currently in the early years of the mine plan used for the Feasibility Study, in this case, a relatively shallow zone on the north-eastern limb of the Indicated portion of Abra’s Mineral Resource.

This drill hole indicated the existence of a potentially mineable domain around 30 metres closer to the surface than the shallowest currently planned mining zone.

The relative shallowness of this area and proximity to early decline development makes it a target for optimisation of the early years of the mine plan and potentially improves risk in that period.

The company has now substantially improved drilling density - particularly over the shallower northern side of Abra - providing opportunities for optimisation of the early years of the mine plan.

Project development continues

Following the receipt of an additional A$20 million investment tranche into Abra Mining Pty. Ltd. (AMPL), and execution of the Taurus Debt Facilities, preparatory construction works recommenced at the project in December 2020.

The final installation of the remaining 200 camp units and other ancillary buildings is underway together with a number of civil works projects on site.

The construction of an explosives magazine was recently completed and site clearing and earthworks involving preparation of sites for the ROM pad, future processing plant, settlement pond and others are underway.

The company continues to target the commencement of the procurement and construction phase of Abra’s plant and deployment of the underground mining contractor in the first half of the 2021 calendar year.

Based on the current schedule, first production of high-value, high-grade lead-silver concentrate at the project will commence within 2022.
