Full Summary

Tanami Gold NL has received final assays for the Reverse Circulation Pre-Collar/Diamond Core Tail (RCD) drilling programs completed at the Groundrush Gold Deposit and the parallel Western Dolerite Prospect, which form part of the Central Tanami Project Joint Venture (CTPJV). The 27-hole program at Groundrush was designed to improve confidence in the Mineral Resource within the targeted area ahead of future resource updates and mining studies. The drilling returned several high-grade intercepts, including 2.00 metres @ 20.02 g/t gold, 4.00 metres @ 6.25 g/t gold, and 0.90 metres @ 29.30 g/t gold. A separate 20-hole RC and RCD program at the Western Dolerite Prospect evaluated the down-dip and northern strike extension of the target, with the best intercept being 14.30 metres @ 1.75 g/t gold. Final assays are still pending for drilling at the Defa Prospect and Jims Gold Mine. The CTPJV is a 50:50 partnership between Tanami Gold and Northern Star Resources, with Mount Gibson Iron recently announcing the acquisition of Northern Star's 50% interest.
