GBM Resources (ASX:GBM) has intersected gold mineralisation outside current resource boundaries at its Twin Hills Gold Project in Queensland.
Hole TNDH048 returned 18m @ 12.01 grams per tonne gold (Au) from 247m at the 309 deposit. The hole includes 2m @ 104.61g/t Au from 247m. The intersection sits about 85m from a previously reported 37m @ 5g/t Au in TNDH012.
Further ‘high-grade’ mineralisation outside the 309 mineral resource estimate (MRE) includes 5m @ 6.66g/t Au from 189m in TNDH048, including 2m @ 16.2g/t Au from 189m, and 5m @ 5.8g/t Au from 118m in TNDH050, including 3m @ 9.44g/t Au from 120m.
At the Lone Sister deposit, LSDH011 returned 37m @ 2.4g/t Au from 285m, including 4m @ 7.77g/t Au from 314m. The hole also returned 18m @ 1.4g/t Au from 328m, including 8m @ 2.43g/t Au from 338m.
CEO Daniel Hastings says the results strengthen the case for resource growth at both deposits.
“The result at 309, roughly 85m from the previously reported 37m @ 5g/t Au, identifies a priority area for follow-up drilling to test the extent and continuity of the mineralisation beyond the current resource,” Hastings adds.
The 50,000m stage two program focuses on growing the Twin Hills MRE, improving confidence in the existing resource, and better defining higher-grade mineralisation. Results continue to extend mineralisation beyond current MRE boundaries at both deposits.
At 309, the Milled Matrix Breccia remains an important host to gold mineralisation and extends beyond the existing resource. Meanwhile at Lone Sister, mineralisation is hosted within altered rhyolite and associated breccias and structures.
The 37m intersection lies outside the current Lone Sister MRE, in the same area as the previously reported 52m @ 2.77g/t Au from 299m in LSDH002.
About 2,150m of drilling assays are pending at 309 and 1,400m at Lone Sister ahead of a planned Twin Hills MRE update.
GBM holds approximately 1.84 million ounces of gold in mineral resources across its flagship Twin Hills, Yandan, and Mt Coolon assets in Queensland’s Drummond Basin.
