THE DRILL SERGEANT: Barra Resources (ASX: BAR) outlined its 2018 exploration program, which will commence with RC drilling at the company’s wholly-owned Burbanks gold project, southeast of Coolgardie in Western Australia.
Barra Resources has completed a geological assessment and strategic review of its gold portfolio which it indicated to have resulted in a comprehensive update to the company’s gold strategy.
“The updated gold strategy is based on an initial Exploration Target of 223,000 to 564,000 ounces of gold for Burbanks alone,” Barra Resources said in its ASX announcement.
“The potential quantity and grade of the Exploration Target is conceptual in nature as there has been insufficient exploration to estimate a Mineral Resource beyond Birthday Gift.
“It is uncertain if further exploration will result in an estimation of a Mineral Resource.”
Barra will kick off the drilling phase of its updated strategy with 4,000m of RC drilling at the high-priority Main Lode Gold Mine.
The Main Lode underground mine produced 146,000 tonnes at 18.3 grams per tonne gold for 85,900 ounces of gold to a depth of 240 metres below surface level between 1885 and 1914.
From 1946 to 1951, Western Mining Corporation accessed Level 8 at Main Lode and undertook extensive strike drive sampling, yielding a pay-run of 160m at 16.1g/t gold at an average width of 0.4m.
Drilling carried out by Barra in 2017 at Main Lode returned encouraging results, including:
11 metres at 5.70g/t gold from 44m;
5m at 9.62g/t gold from 33m;
5m at 8.65g/t gold from 37m;
5m at 3.70g/t gold from 44m; and
5m at 3.29g/t gold from 82m, including 2m at 6.77g/t gold from 82m.
“The 2017 program at Main Lode successfully defined a 400 metres long strongly mineralised zone along the Burbanks Shear to a depth of 70 metres below surface level, immediately adjacent to the historical mine workings,” Barra Resources said.
“This demonstrated the potential for significant resources to be delineated along strike and below the historic underground mining areas.
“Based on this history and results, Main Lode has been deservingly selected as the highest priority drilling target.”
Barra has approvals in place from the WA Mines Department and a drilling contractor ready to go.
The company explained drilling will focus on extending the strike of the existing mineralised zone from 400m to 800m by initially testing an additional 200m of strike extent to the north and south.
The 4,000m program also aims to increase the depth extent to 250m below surface level by testing the next 180m vertically below the 2017 program.
