Aurumin Ltd (ASX:AUN) has described the outcome of resource drilling at the Shillington banded iron formation (BIF) within its 100% owned Central Sandstone Gold Project as a great result, saying it shows an extension to the high-grade mineralisation recently assayed at the Two Mile Hill deposit.
Nine holes for 1,245 metres were drilled at the Shillington open pit, roughly 400 metres to the south of the Two Mile Hill Tonalite, aimed at better defining the Shillington resource.
Drilling was conducted in conjunction with the pre-collars for diamond drilling at the Two Mile Hill deposit, with highlights including:
- 7 metres at 5.78 g/t gold from 137 metres;
- 6 metres at 5.40 g/t gold from 96 metres;
- 8 metres at 4.99 g/t gold from 80 metres; and
- 7 metres at 1.64 g/t gold from 90 metres and 4 metres at 4.54 g/t gold from 101 metres.
Two holes were stopped before reaching target depths due to water affecting drilling and sample quality. They remain open and may be completed with diamond drilling tails at a later date.
The Central Sandstone Project has a 784,000 ounce gold mineral resource.

Single geological complex
Aurumin managing director Brad Valiukas said: “These are some great results from Shillington, indicating a structurally related higher-grade corridor and continuity of grade connecting to the Two Mile Hill deposit.
“Along with the recently completed diamond drilling at Two Mile Hill, this sets us up to now model the Shillington and Two Mile Hill deposits as a single geological complex, with known grade in the banded iron formation, mafic and tonalite.
“We anticipate results for the final two diamond holes, that were drilled at Two Mile Hill, shortly. We look forward to releasing those results and commencing an updated resource model directly after.”
