Exploration

Overview

Scheelite (tungsten) within the Dolphin mining area occurs within carbonate-rich Mine Series rocks in close proximity to the Grassy Granite and against controlling faults. The scheelite mineralisation is the result of chemical interaction between mineralizing fluids from the intruding granite and the Mine Series rocks.

Previous geological investigations have identified over 7km of prospective geology surrounding the Grassy Granite. Numerous high quality exploration targets exist in the area surrounding the proposed mine site. These targets are:

South Bold Head

Historic gravity data and geological mapping suggests Mine Series rocks may be found at depth immediately above a granitic body south of the Bold Head Mine. Key mineralisation bounding faults extending between the historic Bold Head and Dolphin mining areas cut the approximately 500m long target area.

South Dolphin

Mine Series rocks and key mineralising faults are interpreted to occur under Grassy Bay immediately off-shore from Dolphin. This mineralisation could plunge in excess of 500m to the SSE within the Mine Series rocks and adjacent to the Grassy Granite contact.

West Dolphin

Located immediately west of the Dolphin pit within Mine Series rocks, this area is interpreted to host strike extensions to Dolphin. Previous operators of the mine undertook limited diamond drilling in this area, but did not fully drill-test the approximately 7km strike length of the prospective geology. Several high-quality prospects exist in this zone including the Investigator 21 prospect drilled by G6M in 2018 with several ore grade intercepts returned. The results were released to the ASX on 17th May 2018. Further exploration is ongoing.
