Assays for three diamond holes MTDD006-008 intersected gold and copper with notable intersections including:
- MTDD006 15 metres at 2.28 g/t gold from 57 metres;
- MTDD006 21 metres at 2.4 g/t gold from 81 metres;
- MTDD007 22 metres at 0.84% copper, 0.04 g/t gold from 88 metres; and
- MTDD008 9 metres at 1.28 g/t gold from 92 metres.
The depth, grade and width of the mineralisation, especially in hole MTDD006, is supportive of a potential open-pit mining operation.
Depth extensions remain untested
Emmerson’s managing director Rob Bills said: “These latest results from Mauretania have established a very thick ~36-metre zone of gold a mere 57 metre below the surface.
“Furthermore, a new zone of shallow copper mineralisation that also points to the possibility of gold at depth remains untested.
“Particularly as the gold and copper mineralisation are open to the north-west, and that the typical metal zonation in these styles of deposits consist of primary gold beneath the copper.
True gold grades may be higher
“The coarse nature of the gold and poor to no recoveries of some samples in the oxide zone has likely underrepresented the true gold grades, particularly in comparison to adjacent drill holes which assayed 20 metres at 38.5 g/t gold from 92 metres, including 4 metres at 158 g/t gold (ASX: 11 June 2019).
“The thick intercepts of gold and now copper at shallow levels provides great encouragement that Mauretania will be a viable open cut mine – hence our successful application to the NT Government to convert the Exploration Lease into a Mining Lease.”
