THE DRILL SERGEANT: Vango Mining (ASX: VAN) has encountered further high‐grade, gold intersections from a recently completed extension drilling program at the Trident gold deposit, part of the company’s 100 per cent‐owned Plutonic Dome gold project in the Mid‐West region of Western Australia.
Vango Mining explained the program was designed to test deeper parts of the Trident mineralisation system, as well as further defining near surface oxide material on the western side of the deposit.
The drilling has intersected high‐grade gold mineralisation at a distance of 500 metres (down dip from surface) to the west of Trident’s high‐grade drill‐defined mineralised core, which the company has interpreted to indicate a second high‐grade gold system may have been discovered.
Results have been received for three diamond holes and four reverse circulation drill‐holes, including:
3.5 metres at 10.9 grams per tonne gold from 349m, including 1.5m at 22.1g/t gold from 350m.
Vango explained drill hole VTRRCD0028 is the deepest of two deeper holes at Trident, which both intersected the mineralised Trident ultramafic approximately 400m (500m down dip from surface) west of Vango’s current high‐grade drill‐defined area, substantially extending the deposit’s high‐grade gold mineralisation system.
Other results were received from drilling of the near‐surface, western, projection of the Trident deposit, including intersections of:
2 metres at 4.9 grams per tonne gold from 37m, 5m at 1g/t gold from 44m and 3.4m at 3.4g/t from 68.6m, including 1m at 7.2g/t gold;
6m at 3.7g/t gold from 56m, including 1m at 16.2g/t gold, 6m at 1.9g/t gold from 24m, including 2m at 3.2g/t gold and 5m at 2.7g/t gold from 46m, including 2m at 4.9g/t gold;
4m at 1.1g/t gold from 43m and 2m at 2.2g/t gold from 58m in; and
2m at 1.4g/t gold from 24m.
An addition, a very deep hole, (VTRRCD0029), tested the system to around 1000m (down dip) to the west of the high‐grade gold mineralised core at Trident and showed the alteration system extending strongly with a 12m wide zone of biotite alteration.
“This has now been confirmed to be geochemically consistent with the upper parts of the deposit with strong anomalism in potassium, tungsten and molybdenum which are all introduced by the mineralising fluid,” Vango Mining said in its ASX announcement.
“Gold assays were low in this hole, but significant potential remains for gold mineralisation to extend to these very deep extensions of the Trident system.”
