King Island's Bold Head deposit boosts Dolphin tungsten resources by 18%

King Island Scheelite Ltd. said Sept. 26 that inferred and indicated resources at its Dolphin tungsten project in Tasmania, Australia, increased 18% after it completed a JORC 2012-compliant resource estimate for the Bold Head scheelite deposit.

Indicated and inferred resources at Bold Head were estimated at 1.76 million tonnes grading 0.91% tungsten trioxide for 16,080 tonnes of tungsten trioxide, at a 0.5% tungsten trioxide cutoff.

That boosted total resources at Dolphin, which now hosts total resources of 11.36 million tonnes grading 0.90% tungsten trioxide for 102,480 tonnes of tungsten trioxide contained.

King Island noted that the resource estimate for Bold Head was based mainly on historical diamond drilling data, which was digitized and validated in accordance with the 2012 JORC Code.

The addition of Bold Head into Dolphin demonstrated the potential to extend the mine life beyond eight years. The company also said that the Grassy Granite area is also highly prospective for further scheelite resources.

A June feasibility study for Dolphin outlined a pretax net present value, discounted at 8%, of A$146 million, a 47% internal rate of return and a 2.75-year payback period.
