The drill rods have started spinning again at ASX-listed Marmota’s exciting Aurora Tank gold discovery, 50km north-east of the mothballed Challenger gold mine in the Gawler Craton region of South Australia.
The Adelaide-based gold explorer has now resumed drilling at the high-grade Aurora Tank discovery after the 85-hole RC program totalling 7,500m was briefly interrupted by crew rotations, rig repairs and maintenance.
Aurora Tank may set the Gawler Craton alight again, after Rob Mosig’s Helix Resources-led gold rush got punters’ pulses racing and Helix’s share price soaring to $10 in the mid-1990s after Helix discovered the Tunkillia gold deposit in the region.
Marmota set tongues wagging recently when it deployed an innovative “biogeochemical sampling” technique, which essentially involves the sampling of tree matter or leaves, to determine if traces of gold have been sucked up by the plant along with the soil nutrients.
Interestingly, Marmota has been able to identify successful drill targets by using this method.
It has led to a swath of high-grade intercepts from follow-up drilling including 3m going 41 grams per tonne gold from 21m including 1m at 120 g/t and 5m at 27 g/t from 38m including 1m at 105 g/t gold.
Notable previous intersections have also included 4m at 15 g/t from 67m including 1m at 53 g/t, 2m at 67 g/t gold from 32m including 1m at 93 g/t and 3m at 24 g/t from 34m including 1m at 51 g/t.
Other impressive high-grade hits among many were 3m at 29 g/t from 63m including 1m at 74 g/t and 6m at 11 g/t from 40m including 1m at 58 g/t.
Marmota is hoping the results from the resumed RC drilling program will further solidify the case for production at Aurora Tank via a low CAPEX, low operating cost, heap-leach development for the near-surface deposit.
Marmota and fellow explorers Barton Gold, Taruga Minerals, Indiana Resources and others are leading the renewed charge in the venerated Gawler Craton region. Mosig was largely responsible for establishing the credentials of the highly prospective province through the Tunkillia gold discovery almost a quarter of a century ago and the renewed interest in the area is healthy for the industry.
