Group 6 Metals restarts drilling at Investigator 24 Prospect within Dolphin Tungsten Mine

Australian resources exploration and development company Group 6 Metals (ASX:G6M) reports it has restarted exploration drilling at the Investigator 24 Prospect, located within the Dolphin Tungsten Mine on King Island in Tasmania.

Group 6 Metals notes the current round of drilling will focus on Investigator 24, which is located 2km South of Investigator 21, testing the likely southern extent of scheelite mineralisation.

The company says an exploration drill rig has been mobilised to King Island to conduct a drill program, comprising 3 diamond core holes, to test the western margin of the Grassy Granite located south of the Investigator 21 Prospect. A single drillhole as a step-out to the north of Investigator 21 is also planned. This drilling is expected to commence in mid-January.

Group 6 states the planned program comprises up to 1,000m of diamond core drilling and estimates that the program will take around 6 weeks to complete. Assays are also expected to take a further 6 weeks following completion of drilling.

The company says the primary objective of the drilling is to intersect the Upper Grassy Group formation which hosts the tungsten resources at Dolphin and Bold Head. In addition, Group 6 also notes an additional drillhole is targeting an extension of previously encountered mineralisation as a northerly extension of the Investigator 21 Prospect.

Group 6 Metals Chief Executive Officer (CEO) and Managing Director, Keith McKnight says: “While continuing to make exciting progress towards the restart of tungsten production at the Dolphin Tungsten Mine in early 2023, the company is keen to continue developing regional exploration opportunities surrounding the mine, building on the high-grade mineralisation intersects encountered from previous exploration drilling carried out at Investigator 21 in 2018.

Investigator 21 prospect, with similar geology, is located 6km west of the Dolphin Tungsten Mine”

Investigator 21 prospect, with similar geology, is located 6km west of the Dolphin Tungsten Mine. The program carried out in 2018 successfully defined scheelite bearing skarn mineralisation in 3 of the 4 holes, one exceptional high-grade intersections of 3.3m @ 1.7% tungsten trioxide (WO3), which demonstrates the potential to delineate additional high-grade resources outside the current resources and reserves.

It is encouraging to see the exploration rig arrive back on King Island after a 4-year hiatus while we focus on the re-development of Dolphin. High-grade mineralisation has now been confirmed at 3 separate areas around the large granitoid intrusion which gives us a high degree of confidence about the potential to delineate additional high-grade resources outside the current resources and reserves.

This round of drilling will focus on Investigator 24 which is located 2km south of Investigator 21, testing the likely southern extent of scheelite mineralisation. Pending further exploration success, it could see the area really take shape as a potential future resource.”

Previous drilling at the Investigator 21 Prospect conducted in 2018 defined scheelite-bearing skarn mineralisation in 3 holes.

Investigator 21 is located 6km west of Dolphin, and the company states it has similar geology to both Dolphin and the Bold Head Resource. Group 6 reports previously identified intersections confirmed the ‘high-grade’ tenor of mineralisation at 3 separate locations on the periphery of the Grassy Granodiorite which upgrades the overall exploration potential of the mineralised intrusion.

Group 6 also reports pending the success of this and future drilling campaigns, it would seek to delineate an economic reserve which would extend the life-of-mine well beyond the current 14 years.

Group 6 Metals is an Australian resources exploration and development company focused on redeveloping the Dolphin Tungsten Mine located on King Island in Tasmania.

The company states its initial focus is producing a ‘high-grade’ tungsten concentrate, however it also plans value-add the product for supply into the upstream tungsten industry.
