Construction has commenced on site for the redevelopment of Group 6 Metals (G6M) wholly-owned Dolphin Tungsten mine on King Island in Tasmania.

Stripping and stockpiling of vegetation and topsoil commenced on January 26, 2022, following the arrival of the first dozer to the mine site on January 20 and obtaining all the requisite regulatory approvals.

These activities are a precursor to the commencement of bulk earthworks required for the civil works on which the processing plant will be constructed.

“Today is a momentous day for the company, following many years of hard work by the team to reach this point,” Group 6 Metals executive chairman Johann Jacobs said.

“We will be keeping shareholders and the wider market updated regularly now that our construction program has commenced in earnest.”

The commencement of the earthworks is on track with G6M’s expected timeline, with civil works anticipated to begin shortly.

The Dolphin Tungsten mine is host to the highest-grade tungsten deposit of significant size in the western world.

In November last year, Gekko Systems was awarded a $49 million contract for the design, procurement, construction and commissioning of the processing plant and related facilities at the Dolphin mine.

The Gekko contract predicts that facilities will commence in the first quarter of 2023.

The redevelopment will initially focus on producing a high grade of tungsten concentrate, with plans well advanced to value-add the product for supply into the upstream tungsten industry.

The Dolphin Tungsten mine operated between 1917 and 1992 when it was closed due to extremely low tungsten prices, rather than a lack of reserves.

At that time, approximately 50 per cent of the known resource was yet to be mined.

The current development plan envisages an eight-year open cut mine followed by a six-year underground mine producing a concentrate for supply into the market.
