HIGHLIGHTS

·       Detailed assessment of the recently flown airborne EM geophysical survey is underway to identify many future targets for follow-up on-ground mapping and geochemical assessment and possible drill testing.

·       The drill rig has now relocated 12 kilometres to the west of the known high-grade deposits and has commenced testing at the under-explored northern limb of the Company’s 475km2 strategic tenement package.

There are already two high grade deposits at the Red Mountain Project, with an Inferred Mineral Resource of 9.1 million tonnes @ 12.9% ZnEq2 for 1.1 million tonnes of contained zinc equivalent.

Summer field exploration activities commenced in late May with on-ground activities including surface reconnaissance mapping, surface geochemical sampling (soils and rock chips), ground electrical geophysics (MT and CSAMT), downhole EM surveys and diamond drilling.

Final data from the 500km² airborne electromagnetic (AEM) geophysical survey, which was flown in April and May this year, has now been received and is being integrated with surface geochemistry to prioritise a number of identified VMS targets for drill testing.

Results from the AEM survey show a signature conductivity response at both of the two known high-grade massive sulphide deposits at Dry Creek and WTF. This knowledge is now being used to search for similar look alike responses elsewhere within the Company’s tenement package.

The graphitic unit at the base of the Sheep Creek Member is a distinctive marker horizon along the northern limb of the targeted syncline representing an equivalent horizon to that hosting the high-grade WTF massive sulphide mineralisation, where the Inferred Mineral Resource for WTF stands at 6.7Mt at 6.2% zinc, 2.8% lead, 189 g/t silver and 1.1 g/t gold for a grade of 14.4% ZnEq2.
