Aurumin Ltd (ASX:AUN) is set to restart drilling next week at its 100%-owned Mt Dimer Gold Project, 120 kilometres northeast of Southern Cross in Western Australia.
Mt Dimer is a historical high-grade production centre, having produced more than 125,000 ounces of gold, including open pit and underground production of 600,000 tonnes at 6.4 g/t gold.
Aurumin has planned a total of 2,500 metres of drilling to be completed with all required approvals in place.
A drill rig has been secured and mobilisation is planned for the week commencing July 12, 2021.
Building on previous success
Aurumin has developed the program based on previous successful drilling at the existing deposits of Lightning, Golden Slipper and LO3.
In addition, the program will target newly identified mineralised structures of Frodo North (T6), T12, and T24 discovered during Aurumin's recent sub-audio magnetic (SAM) survey target drilling.
Aurumin will also target a new prospect north of the Karli West open pit based on historical soil sampling and site mapping.
The company expects the drilling program will take about three weeks to complete, with assays to be received and interpreted after five weeks.
Historic high-grade deposits
Aurumin will begin drilling at Lightning deposit to follow up a potential new high-grade ore shoot that returned 4 metres at 4.39 g/t gold.
In the case of Golden Slipper, the focus is on previously identified high-grade ore shoots and the follow-up of recent drilling that returned 7 metres at 7.55 g/t.
Additionally, Aurumin’s LO3 program is designed to target the downdip continuation of high-grade ore shoots which were previously mined both in open pit and underground.
Lastly, The company will test for northerly trending mineralised structures within the Karli Northwest (T2) anomaly, along strike of Karli West with a drill line across the anticipated structure.
Newly identified prospects
Aurumin’s Frodo North T6 prospect drilling is designed to target extensions to mineralisation along strike of the Frodo open pit and to follow up on a mineralised structure identified in two holes on a single drill line.
The company’s T12 target was intersected by two reverse circulation (RC) holes on a single drill line testing for northerly trending structures identified using the SAM survey.
This structure occurs as a massive quartz vein with associated pyrite and limited quartz outcrop to the southeast of Golden Slipper and drilling aims to confirm the structure north and south of the outcrop and linking into other mineralisation.
Likewise, the T24 target was also intersected by two RC holes on a single drill line testing for northerly trending structures adjacent to the SAM survey and supported by soil geochemistry in Aurumin's March 2021 drilling program.
