The Directors of Tyranna Resources Limited ("Tyranna") (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 assay results from a further 18 reverse circulation (RC) holes drilled at the Campfire Bore Gold Prospect, which is approximately 37 km from the Challenger Gold Mine and part of the large Jumbuck Gold Project in the Northern Gawler Block of South Australia. These results in addition to previous drilling at Campfire Bore indicate that the targeted structure is continuous along strike.
Holes 16CBRC034 to 16CBRC051 were drilled to test different possible orientations of gold bearing structures discovered by Tyranna earlier in 2016. Historically, Campfire Bore has been the target of multiple generations of drilling however the orientation of the ore zones has never been clearly understood. These first results appear to have identified the prevailing strike of one of these structures and it has opened up the possibility that many parallel structures exist.

Drilling intersected gold bearing zones including [email protected]/t Au from 74m in 16CBRC035 which included [email protected]/t Au - as shown in Figure 1. This occurs below the intercept of [email protected]/t Au from 47m in 16CBRC022 from earlier this year (see figure 2). This hole has importantly confirmed that the structure is steeply dipping to the southeast.
Drilling on a line 50m to the south from the section A-B confirmed the continuation of the mineralisation with an intercept of [email protected]/t Au from 38 meters. An intercept of [email protected]/t Au from 32m in 16CBRC033 from earlier this year occurs on a line 50m again to the south, confirming this structure extends for at least 100m.
The target structures had been drilled with a presumed strike azimuth of 128. Phase 1 and Phase 2 drilling has now confirmed a continual structure which had been defined so far along a strike length of 1.6km.
Commenting on these results, MD Bruno Seneque said, "With these results adding to previous drilling and geological modelling at Campfire Bore, we are uncovering a multi zone structure that is mineralised in all directions and along 800m strike that could extend further. Campfire Bore is developing as a potential gold project discovery and we are looking forward to further enhancing the scale with targeted drilling now that we have more understanding of the geological model."

Diamond Drill Hole (16CBDH001) - Results Pending
A single diamond hole was drilled under the primary structure located in Figure 1 (1m @ 10.5 g/t ) to gain a better understanding of the orientation direction. The expected primary zone was intersected at 86-87m.
Figure 3 shows a sample of diamond hole 16CBDH001. The grey metallic mineral associated with the quartz vein is arsenopyrite and gold is intimately associated with arsenopyrite at the Campfire Bore Gold prospect.
