Tyranna Resources is on track to upgrade and increase confidence in the mineral resource at its Campfire Bore prospect at the emerging Jumbuck gold project in South Australia after intersecting supergene oxide gold close to surface.
Assays from RC drilling at the prospect returned top results of 15 metres grading 3.02 grams per tonne gold from 36 metres down-hole including 6m @ 5.13g/t gold, 7m @ 2.19g/t gold from 12m including 1m @ 11.6g/t gold and 12m @ 1.58g/t gold from 39m in separate drill holes
The infill drilling campaign was aimed partly at upgrading the existing inferred mineral resource of 2.78 million tonnes grading 1.2g/t gold for 109,000 ounces, to the more confident indicated resource category.
Campfire Bore is one of several prospects that make up the company’s larger Jumbuck gold project that collectively holds 8.7Mt @ 1.1g/t gold for 319,000 gold ounces.
Tyranna Managing Director Bruno Seneque said: “Finding good grades so close to surface was a welcome surprise and interfacing the supergene at these levels underscores our confidence in this project.”
“The closer spaced drilling will also allow the Tyranna team to shore up internal structural and mineralisation models which will have a positive impact for exploration, not only at Campfire Bore, but over the whole Jumbuck project area.”
The latest results follow on from drilling completed in 2016 that also intersected high grade supergene oxide mineralisation near surface.
Some notable results from the previous campaign include 5m @ 8.1 g/t gold from 36m including 1m @ 36.8g/t gold, 1m @ 37.8 g/t gold from 47m, 1m @ 30.5 g/t gold from 41m and 3m @ 8.2 g/t gold from 32m.
Jumbuck is located west of BHP’s Olympic Dam mine, in the highly prospective Western Gawler Craton in SA, and just 40km north of the Challenger gold operation.
Tyranna controls nearly 10,000 square kilometres of exploration tenements around the mine, which has reportedly produced over 1 million ounces since commencing in 2002.
