Challenger Exploration announced that assays for the bottom half of the discovery drill hole GNDD-025 have extended the scale of the discovery of a new style of intrusion-hosted gold mineralisation at the Company's Hualilan Gold Project. Drill hole GNDD-025 has returned a complete intersection of 88 metres at 0.94 g/t gold, 2.2 g/t silver, 0.1% zinc from 53 metres to the end of the hole in dacite porphyry containing iron oxide, silica, and pyrite alteration (previously 50 metres at 1.4 g/t gold, 3.4 g/t to 103 metres). Importantly, mineralisation remains strong and open at depth, with the final two metres of the hole grading 1.0 g/t gold and 0.5 g/t silver. The top of the intercept includes a higher-grade zone of 37 metres at 1.8 g/t gold, 4.2 g/t silver down to the base of oxidation which occurs at 90 metres downhole, which is potentially related to supergene enrichment. GNDD-025 is located in the Gap Zone between Cerro Norte and Cerro Sur, an area with limited historical drilling, some 300 metres along strike from any prior CEL drilling. The mineralisation in GNDD-025 is a new type of intrusion-hosted mineralisation in dacite porphyry. The historical high-grade mineralisation at Hualilan occurs in faults and as limestone replacement bodies. The high-grade skarn target remains a priority for the project. Drill hole GNDD-032 recently extended the high-grade mineralisation 100 metres further south of Cerro Norte into the Gap Zone with an intersection of 5.75 metres at 9.5 g/t gold, 29 g/t silver, 3.5 % zinc. This high-grade skarn has also been mapped in outcrop in the southern 500 metres of the Gap Zone at Pizzaro and Puntilla, an area yet to be tested by drilling.
