In December, the first reverse circulation (RC) drilling at the Hub discovery traverse followed-up initial shallow aircore results.
The aim was to test mineralisation at depth and along the interpreted strike.
Composite samples from the RC program have been re-sampled on 1-metre intervals, highlighting excellent grades within the original intervals.
Best results include:
- 4 metres at 9.28 g/t gold within 12 metres at 4.55 g/t from 40 metres;
- 2 metres at 6.89 g/t within 7 metres at 3.96 g/t from 177 metres;
- 1 metre at 10.50 g/t within 3 metres at 5.18 g/t from 250 metres; and
- 1 metre at 7.89 g/t from 35 metres.
The 1-metre samples have also confirmed the 5-metre results, providing better granularity on grades and widths.
Gold mineralisation is steeply dipping and of similar orientation to NTM’s other Redcliffe deposits.
“Good widths and good grades”
NTM Gold’s managing director Andrew Muir said: “The RC drilling highlighted the significant potential of the Hub prospect with good widths and grades.
“In addition, the mineralisation continues at depth with the deepest intersection returning 3 metres at 5.18 g/t gold from 250 metres.
“More drilling is required to understand the strike and depth of the mineralisation, as well as the geometry and influence the mafic dyke may have on the mineralisation.
“Follow-up drilling has commenced at Hub, with drilling at other prospects to follow thereafter.”
NTM plans an initial five holes in the new program and on completion the RC rig will test other prospects within the Redcliffe project including Nambi, Bindy North, Infinity and Mesa West.
A diamond program is also being planned to test high-grade depth extension at a number of deposits, including Nambi, Bindy and GTS.
Regional aircore drilling will be carried out in the March quarter with targets to include the 800-metre strike north of the Hub prospect, as well as further holes around the Infinity prospect.
