Tumblegum South

Figure 3 - West Bryah Project location
  • Existing mining lease ML51/888 directly along strike from the Tumblegum Pit which was mined by Dominion during the 1987–1992 Gabanintha Gold Mine Joint Venture.
  • In 2020, the maiden mineral (Inferred) Resource estimate for the project was announced, totals 600kt, at a grade of 2.2 g/t Au.
  • Current focus is on gold, but there is significant Copper potential on the lease.

The geological setting is interpreted as the eastern side of a syncline, within a mafic/ultramafic volcanic suite, overlain with BIF/sediments/felsics.

This area has undergone intense folding and shearing, with the major shear structure dubbed the “Gabanintha Shear”.

This pattern of folding and shearing along the contact is seen throughout the region

  • Model is based on 49 RC holes, with a total of 5,640m drilled.
  • Gold recovery of 90% based on 20 samples – consistent with historical mining.
  • Indicative shell design based on a series of optimisations
  • Executed Gold Processing Agreement in place – ore to be processed by third party.

NB: Based on Inferred Resource model

 

TUMBLEGUM SOUTH PIT NUMBERS

  • Considerable potential upside on lease, along strike of current deposit and at depth
  • Scope for further discovery inside the current project area, within the Mine Lease area.
  • Further work to convert mineralisation into Resources is being planned.

  • Drilling targets to test possible extension of high-grade plunging lode.
  • Potential to increase mineralisation/ Resource, and then design pit shell.
