Tyranna Resources Limited, as manager of the Western Gawler Craton Joint Venture which includes WPG Resources Ltd. and Coombedown Resources Pty Ltd. announced assay results from 35 reverse circulation (RC) holes drilled at the Campfire Bore Gold Prospect, which is approximately 37 km north of the Challenger Gold Mine and part of the large Jumbuck Gold Project in the Northern Gawler Block of South Australia. The results from hole 18CBRC035 intersected mineralisation only 12m (down hole) from surface at Campfire Bore which indicates potential shallower mineralisation than previously found. Previous drilling in 2016 also intersected shallow high-grade supergene mineralisation.

Holes 18CBRC001 to 18CBRC035 were drilled to test the shallow nature of the supergene mineralisation zones, the average vertical depth to the zones was approximately 30m from the surface, with one hole in particular 18CBRC035 intercepting the zone from 12m below the surface.
