Marmota kicks off drilling at SA gold play

Marmota Limited has kicked off its largest ever RC drilling program at the Aurora Tank gold project, located just 50 kilometres north-east of the mothballed Challenger gold mine in the well-endowed Gawler Craton of South Australia. The company plans to plough some 7,500 metres of drilling into gold targets that present multiple opportunities for high-grade extensions.

A combination of near surface super high grades, soft, potentially free-digging ground and simple metallurgy make Aurora Tank an interesting gold play that features a list of impressive drill hits to-date such as 3 metres grading 29 grams per tonne from 63m, including 1m grading 74g/t gold.

The company is targeting extensions to the recently discovered NW Flank, eastern extensions to the main Aurora Tank mineralised zone and extensions of the primary mineralisation at depth.

The NW flank has already thrown up a lucrative looking 5m drill intersection grading 27g/t gold and since its discovery, Marmota has doubled the mineralised footprint there, which now spans nearly 200m and importantly, it is still open to the north-east.

The NW flank appears to be well and truly open at depth too, bounded to the north east by a high grade 1m intercept grading 9g/t.

Other notable intercepts from the main Aurora Tank zone are 4m z grading 15g/t from 67m, including 1m grading 52.5g/t.

Marmota is also planning to fill in areas at Aurora Tank, which the company said will aid future resource modelling efforts.

Deeper holes are also planned in areas across the Aurora Tank main zone, where earlier holes did not intersect primary mineralisation.

Primary mineralisation identified at depth may just help to drive any optimal pit designs at Aurora Tank down even deeper too.

Early this year, Marmota undertook a study on the microscopic characteristics of the gold at Aurora Tank. With the deposit featuring such high gold grades, the company sought to determine whether mineralisation could be expected to continue at depth.

Marmota found that the gold is largely primary, meaning that it is sitting right where it was originally precipitated and has not been re-deposited through other processes and is not secondary in nature.

The abundance of primary mineralisation of such high-grade is very encouraging, particularly as we embark on drilling deeper, below the weathered zone.

…This is Marmota’s largest ever RC drill program at Aurora Tank and with a special focus on primary mineralisation extensions.

It is shaping up as one of our most interesting, varied and exciting drill programs to date.

Just yesterday, the privately owned Barton Gold kicked off a significant drilling program of its own at its Tarcoola gold project, just south of its dormant Challenger gold mill that is within striking distance of Marmota’s ground.

If Barton can prove up enough ore at Tarcoola to kick start Challenger again, Marmota may well have a toll treatment option for its ore on its doorstep.
