Technical team to plan further program for March commencement
The Directors of Tyranna Resources Limited (ASX: TYX), as manager of the Western Gawler Craton Joint Venture which includes WPG Resources Ltd (ASX: WPG) and Coombedown Resources Pty Ltd are pleased to announce the final batch of assay results from reverse circulation (RC) holes and diamond drilling (DH) drilled at the Campfire Bore Gold Prospect, which is located approximately 42 km from the Challenger Gold Mine and part of the large Jumbuck Gold Project in the Northern Gawler Block of South Australia.
Phase 2 drilling for 2016 at the Campfire Bore prospect has now been completed and all assays have been received. A total of 37 RC holes were drilled for 2,658 metres, and one Diamond Hole completed for 100 metres. The Joint Venture partners are pleased that the drilling to date at Campfire Bore has delineated a consistent supergene gold blanket at the transition zone between the oxidised and fresh rock boundary. This is evident from multiple drill intercepts with grades greater than 30 g/t Au that have been attributed to supergene enrichment (refer figure 1):
16CBRC022 1 m @ 37.8 g/t Au from 47m
16CBRC015 1 m @ 36.8 g/t Au from 42m
16CBRC038 1 m @ 30.8 g/t Au from 56m
16CBRC029 1 m @ 30.5 g/t Au from 41m
Most encouragingly, the results of this program of drilling proves the mineralised structure extends below the supergene blanket and into a primary zone. The implication is that deeper drilling is required to extend the gold zone and thus increase resource potential. Refer to Figure 2 which shows diamond drill hole 16CBDH001 and 16CBRC035 which both intersected primary style gold mineralisation.
Diamond hole 16CBDH001intersected 19m @ 1.01 g/t Au from 37m, including 7m @ 1.9 g/t Au from 37m. In the mineralised zone, evident from this diamond hole, sampling was taken at 1 metre intervals however the intervals sampled did not replicate the mineralised structures known as the "blue quartz vein" (refer Figure 3) which ranges from 10cm to 60cm in length. A new sampling programme will be undertaken to sample only the blue quartz veins in the mineralised structures to show a true reflection of the irregular distribution of the nuggety gold which is similar to the gold mineralisation at the Challenger Gold mine - refer WPG Resources Ltd September 2016 Quarterly Activities Report which reported the following significant intercepts from Challenger South South West (CSSW):
15CUD1616: 0.88m @ 55.35g/t Au from 132.16m
15CUD1616: 1.03m @ 17.53g/t Au from 275.97m
15CUD1617: 1.00m @ 12.00g/t Au from 251.00m
15CUD1725: 0.39m @ 28.49g/t Au from 105.00m
15CUD1760: 0.30m @ 55.19g/t Au from 194.71m
Tyranna Resources MD Bruno Seneque commented, "The sampling of the DD core at 1m sections, while showing the consistency of the structure, did dilute some of the high grade gold hits that are visible in the core and at Figure 3. Notwithstanding that, the JV is very encouraged that the drill program continues to enhance this gold prospect and we are very keen to extend this discovery in 2017."
