Emmerson Resources Ltd (ASX:ERM) (FRA:42E) has kicked off a 1,700-metre diamond drill program at its Kadungle project in New South Wales, to test below shallow epithermal gold mineralisation and also for deeper, porphyry-style copper-gold.
Further, large 3D MIMDAS geophysical survey at its Kiola project show promising early results - aimed at vectoring to the core of the copper-gold mineralisation and directing the next round of drilling planned for early 2021.
Both projects are within the prolific but still highly prospective Macquarie Arc of the Lachlan Fold Belt of NSW, a region that hosts more than 80 million ounces of gold and in excess of 13 million tonnes of copper.
Drilling underway at Kadungle
The first drill hole KAD-prop 1 at Mount Leadley is now underway and will test beneath the quartz-pyrite zone some 200 metres east of historical hole KDD002, which intersected 12 metres at 7.7g/t gold and 0.12% copper.
The main target, however, is around 850 metres, where the vectors from the chlorite alteration and the geology suggest a potential source at depth.
There is no historical drilling in this vicinity and the geological interpretation is based on drilling to the west where a shoshonitic porphyry dyke yielded 6 metres at over 1% copper.
Emmerson Resources expects this drill hole may be extended, providing the mineralisation and alteration is consistent with approaching the source of the copper and gold as at these depths, this style of deposit is still well within the economic parameters for mining.
The second drill hole KAD-prop 2 at Mount Leadley South will also test deeper extensions to the silica-pyrite zone and gold, where the alteration vectors coincide with a steeply dipping fault, interpreted to be the feeder fault for the copper and gold mineralisation.
Next round of Kiola drilling
Emmerson said with early results showing promising results at the Kiola project, a large 3D MIMDAS geophysical survey is targeted at vectoring to the core of the copper-gold mineralisation and directing the next round of drilling planned for early 2021.
Drill follow-up at Sebastopol
Seven drill holes for around 1,500 metres are now expected to start in February 2021 at the Sebastopol Gold Project due to rescheduling activities around the seasonal harvesting of crops.
The greater Sebastopol area was originally identified for its porphyry copper-gold potential, however, minimal modern exploration across this historic high-grade goldfield provides potential for the discovery of orogenic gold deposits.
Fieldwork has now traced multiple subparallel veins, historic workings and prospects over an area of 4 square kilometres and assay results from both historical and recent sampling have yielded up to 75.8 g/t gold.
Kadungle and Sebastopol added to alliance
Emmerson and Longreach Mineral Exploration have reached agreement to include the Kadungle and Sebastopol projects to their exploration alliance portfolio.
Exploration costs will be shared equally and in recognition of Emmerson’s investment in the early stages of exploration at Kadungle, any future joint venture will be structured on a 60% equity interest to Emmerson.
The Sebastopol project has also been accepted as a strategic alliance project with all costs and equity interest on a 50/50 basis.
