Challenger Exploration announced the results from drillhole GNDD-182 at the company's Hualilan Gold project in San Juan province, Argentina. The hole was designed to confirm that drill hole GNDD-128 (20.0m at 0.5 g/t AuEq), collared 50 metres to the west of GNDD-139 (207.5m at 0.8 g/t AuEq) had defined the western limit of the zone of intrusion-hosted mineralisation in the Gap Zone. GNDD-182 recorded an intersection of 19 metres at 0.4 g/t AuEq (0.4 g/t gold, 1.0 g/t silver, 0.1% zinc) from 92m, hosted in shales which is consistent with marker mineralisation in the shale which overlies blind mineralisation in the intrusive. From 126.0 metres to the end of the hole limestone was intersected as expected. Within the limestone, unexpected massive sulphide in skarn which returned 4.3 metres at 36.6 g/t AuEq (31.8 g/t gold, 97 g/t silver, 8.1% zinc) from 148.7 metres, including 3.45 metres at 45.5 g/t AuEq (39.6 g/t gold, 118 g/t silver, 10.0% zinc) from 148.7 metres was intercepted. The skarn mineralisation is typical of the high-grade Main Manto at Cerro Norte. Additionally, this intercept is located at the projected down-dip extension of the Main Cerro Norte Manto at the location of GNDD-182. GNDD-182 was collared 200 metres south-west of the nearest hole to intersect high-grade skarn mineralisation (GNDD-035). GNDD-035 intersected 5.75 metres at 11.5 g/t AuEq (9.5 g/t gold, 29 g/t silver, 3.5 % zinc) from 89 metres including a higher grade zone of 3.15 metres at 19.9 g/t AuEq (17.1 g/t gold, 29 g/t silver 5.6 % zinc). At the time, GNDD-035 had itself extended the high-grade Main Manto mineralisation 100 metres south along strike into the Gap Zone. This is the first time the high-grade Main Manto skarn mineralisation has been intersected to the west of the intrusives in the Gap Zone which opens significant scope to expand the high-grade skarn to the west. The mineralisation remains open down dip and the company intends to fast track a drill hole to test for extensions to this mineralisation 40-50 metres down dip.
