THE DRILL SERGEANT: Recent drilling carried out by Australian gold producer Focus Minerals at its Tindals Mining Centre underground operation has resulted in a series of high-grade gold intercepts, which the company said highlights potential for further expansion around the Perseverance deposit.
Focus has also just poured its 200,000th ounce of gold since it started production from the Tindals underground operation in April 2008.
Approximately 125,000 ounces of that production has been mined from Perseverance.
“Perseverance has been an important ore body for Focus over the years and its production has been exceptional when you consider we only started there with a 76,000 ounces reserve,” Focus Minerals chief executive Campbell Baird said in the company’s announcement to the Australian Securities Exchange.
The recent campaign has targeted previously identified mineralisation to the north of the existing reserve, called the Perseverance North deposit, where Focus has outlined a 150 metre strike length of high-grade mineralisation, which remains open to the north and down dip.
Perseverance North was targeted to assess the southern strike potential as well as infill around previous high-grade results.
Focus said the drilling result appear to indicate Perseverance North has a moderate-steep southerly plunge, similar to the main quartz-sulphide ore body at Perseverance.
Recent drilling results at the main lode at Perseverance, including 4.5m at 21.6 grams per tonne gold, 2.3m at 12.3g/t gold, and 2m at 7.8g/t gold, have also confirmed a mineralised diorite lode west of, and running parallel to, the current Perseverance Ore Reserve.
High grade intercepts at the Perseverance North deposit include:
– 6 metres at 20.2 grams per tonne gold;
– 2.4m at 16.3g/t gold;
– 2.8m at 10.8g/t gold; and
– 2.7m at 10.0g/t gold.
High-grade intercepts in the diorites include:
– 16.9m at 16.0 g/t gold;
– 6.1m at 7.0g/t gold;
– 3m at 12.4g/t gold; and
– 9m at 3.5g/t gold.
“These results point to the potential for further expansion around the Perseverance ore body and, when you put them together with other work we’ve been doing across the wider underground operation, we are clearly in a very strong position to continue to deliver solid production from the Tindals underground month after month,” Baird said.
