Aurumin Ltd (ASX:AUN) has unearthed a 352.8-metre gold hit, weighing in at 1.5 g/t, during diamond drilling at its wholly-owned Central Sandstone Gold Project in WA.
The gold result came from the third hole in the company’s reverse circulation (RC) and diamond drilling program, recording 529.2 gram-metres.
Exploration is underway across Central Sandstone’s Shillington and Two Mile Hill deposits, where the company is out to extend and better define the inferred, 500,000-ounce underground resource.
Some of the highlights within the 352.8-metre intersection include:
- 12.8 metres at 2.9 g/t from 298.2 metres;
- 8.4 metres at 9.3 g/t from 392.2 metres, including 0.6 metres at 119 g/t from 396.4 metres;
- 14.8 metres at 2.2 g/t from 461.2 metres; and
- 25 metres at 5.4 g/t from 531.2 metres, including 0.85 metres at 80.6 g/t.
RC drilling paves the way
In late August, Aurumin returned a 7-metre, 5.78 g/t gold hit during a reverse circulation (RC) drill program at Central Sandstone.
The company’s nine-hole, 1,245-metre drill campaign originally set out to test for links between Central Sandstone’s Shillington and Two Mile Hill deposits.
It also sought higher-grade mineralisation along a structurally controlled corridor in a bid to improve and extend the Shillington resource.
Some of the strongest assays from that program included:
- 6 metres at 5.4 g/t from 96 metres;
- 8 metres at 4.99 g/t from 80 metres;
- 7 metres at 1.64 g/t from 90 metres; and
- 4 metres at 4.54 g/t Au from 101 metres.
However, these holes remain open and could be extended with diamond drilling tails at a later date.
Combined with its fresh diamond assay, the explorer is preparing to complete further drilling to underpin a resource model update in the near future.
Exploring a single geological complex
Commenting on the findings at Central Sandstone, Aurumin managing director Brad Valiukas said the assays primed the company for its next work phase.
“This is another great result and, along with the previously released diamond results, continues to add to the picture at Two Mile Hill,” he explained.
“Along with the recently completed RC drilling at Shillington, this sets us up to now model the Shillington and Two Mile Hill deposits as a single geological complex.
“We anticipate results for the final diamond hole and RC pre collars shortly.
“We look forward to releasing those results and commencing an updated resource model directly after.”
