Tennant Minerals Ltd (ASX:TMS) has obtained further, outstanding, high-grade copper and gold results from the latest diamond drilling programme at the Bluebird copper-gold discovery, on the company’s 100% owned Barkly Project, 40km east of Tennant Creek in Australia’s Northern Territory.
The new results include thick and high-grade copper and gold intersections in BBDD0025 – 16.45m @3.05% Cu and 2.31g/t Au from 203.65m (downhole), incl. 8.35m @2.35% Cu and 4.47g/t Au from 203.65m, incl. 3.8m @0.87% Cu and 9.08g/t Au from 203.65m incl. 1.03m @1.47% Cu, 28.3g/t Au, and incl. 3.4m @8.22% Cu and 0.16g/t Au from 216.7m incl. 1.1m @22.6% Cu.
“The continued intersection of high gold and copper grades at Bluebird, over thick intervals, confirms that we are onto a genuine high-grade copper-gold discovery,” Chairman, Matthew Driscoll, said.
“Bluebird remains completely open in all directions and we will now drill for immediate extensions along strike and at depth, with the aim of defining a multi-million tonne high-grade mineral resource of similar tenor to the historically mined Peko deposit, 20km west of Bluebird, which produced 3.7Mt of 4% copper and 3.5g/t gold from the 1930s to the 1970s.
“We are also confident our upcoming IP geophysical program will identify more Bluebird look-alike targets for drill testing along the 2.5km Bluebird-Perseverance Corridor.
“The potential for multiple high-grade copper-gold discoveries along this 2.5km corridor significantly enhances the scope for our 100% owned Barkly Project to be developed into a stand- alone mining operation.”
The high-grade copper and gold results in BBDD0025 are down dip of the previous bonanza gold intersection in BBDD0021 of 24m @0.66% Cu, 11.8g/t Au including 5.7m @0.74% Cu and 49.3g/t Au and 40m along strike and down-plunge to the west of the spectacular intersection in BDD0018 of 30.5m @6.2% Cu, 6.8g/t Au including 17.8m @5.2% Cu, 11.5g/t Au.
The footprint of the Bluebird discovery is already of similar dimensions to other high-grade copper-gold deposits mined at Tennant Creek. These include the Peko mine, just 20km west of Bluebird which produced 3.7Mt of ore grading 4% Cu and 3.5g/t Au3 from the 1930s, closing in the 1970s.
The Warrego deposit, which was the last major mine at Tennant Creek, occurs at the western edge of the Tennant Creek Mineral Field and produced 6.75Mt @6.6 g/t Au, 1.9% Cu3 from a fully preserved deposit (un-eroded). Bluebird is similarly fully preserved, with the top of the deposit at 80m below surface and geophysics indicating continuations at depths greater than 400m below surface.
