Marmota has announced that its June drilling program at Aurora Tank has yielded high-grade gold intersections at its Aurora Tank project in South Australia.

The company stated that drilling yielded an outstanding intersection of 4 metres @ 30 g/t gold (20 metres from surface) in Hole 19ATAC049, located 120 metres south of their 5 metres @ 27g/t gold intersection recently featured in ‘Top Drill Intersections per State – Australia – Q1 2019’ published by the RSC Mineral Intelligence Report.

Additionally, extensional drilling on the NW flank has established a new high-grade zone to the NW, with multiple new high-grade intersections including 4 metres @ 10g/t (Hole 19ATAC069), 4 metres @ 8.9 g/t and 4 metres @ 8 g/t (Hole 19ATAC065), which are all located close to surface. The zone appears to be over 100 metres long and is open in a number of directions.

Tree leaves has also yielded a new discovery gold hole located 450 metres to the NE.

By targeting elevated gold in tree leaves outside the known area of mineralisation (recon drilling), Marmota has made a new discovery hole 19ATAC098 located approximately 450 metres north of the Aurora Tank mineralised zone and intersecting 6 metres @ 3.4 g/t gold (from 44 metres to end of hole).

The reconnaissance component of the drilling program was designed to see if new gold mineralisation can be found outside the known mineralisation area at Aurora Tank.

Marmota Chairman, Dr Colin Rose, said that this was Marmota’s sixth successive drilling program at Aurora Tank.

“Each and every one of those programs has been a success,” said Dr Rose.

“I find it particularly exciting and remarkable that we have identified a new discovery hole 450 metres from known mineralisation, at 44 metres below surface, based entirely on tree leaves from a senna tree, with 6 metres at 3.4g/t, from 44 metres to end of hole.

“All the ingredients are coming together: High-grade mineralisation close to surface, excellent gold recoveries from metallurgical testwork, and potential low-cost low-capex open-pittable production methods.

“I further note that Marmota has commissioned column leach tests to assess the project’s suitability for low-cost heap leach production.”

This discovery hole 19ATAC098 was drilled to test a biogeochemical (Senna tree leaf) gold anomaly.

This result is the most significant over an area about 1 kilometre across and it remains open at the end of the hole at 50 metres in depth. It suggests a new zone of potentially economic mineralisation. Other nearby holes contain what looks like secondary dispersion mineralisation suggesting the new zone is open in several directions.

Additional drill holes are required to follow up the new mineralisation.
