OPERATIONAL UPDATE – LUTWYCHE / KOOKABURRA DRILL RESULTS

Highlights
  • Results received & interpreted from previously unprocessed diamond holes to further evaluate the Lutwyche/ Kookaburra tin-tungsten system
  • Results included 0.20m @ 4.10% Sn, 0.30m @ 1.47% Sn, and 1.5m @ 0.71% Sn
  • Zones correspond to veins mapped at surface, and extending to historical underground development 350m below surface
  • Work confirms Lutwyche/ Kookaburra prospect is a significant tin and tungsten narrow-vein system
TNT Mines (ASX: TIN, “TNT” or the “Company”) is pleased to provide an operational update on its Tasmanian tin and tungsten projects, where it has been working up targets around the historical tin-tungsten mining operations and infrastructure at Aberfoyle and Storey’s Creek. The new Board has focused on the unmined Lutwyche-Kookaburra quartz vein system as a key brownfield target.

Lutwyche-Kookaburra comprises up to six narrow but strongly mineralised veins that are accessible via surface shafts and from existing underground development extending from the Aberfoyle mine, 350m below surface. The combined vein system has been previously considered to offer a target comparable to Aberfoyle (past production 2.1 Mt of @ 0.91% Sn and 0.28% WO3*).

As part of the review, two previously un-sampled surface diamond drill holes (LDD002 & LDD003) were logged and processed. Assay results confirm that narrow quartz veins logged in core are tin mineralised, and correspond to veins mapped at surface and extending downward to historical underground development.

LDD02 was drilled to test a strike extension position of the Johnsons/Pay veins, an oblique structure extending between the sub-parallel Lutwyche and Kookaburra veins. Multiple narrow veins were intersected, with assay results including 0.30m @ 1.47% Sn and 1.5m @ 0.96% Sn (see Figures 2 & 3 and Table 1). A historical diamond hole LDD01 that tested the same structure 150m to the south-east (Figure 2) also contains veins with high-grade tin and tungsten intercepts including 0.20m @ 8.9% Sn, and 0.20m @ 0.64% Sn & 6.3% WO3.
