The near-surface copper oxide minerals in drill holes DCH-97 and DCH-80 had acid solubilities of 83% and 79%, and total solubilities of 92% and 87%, respectively. According to Camino, these solubility results confirm the continuity of oxide mineralization to a depth of at least 100 metres in the new zone.
The drill holes were completed as part of Camino’s July 2022 drilling campaign. DCH-97 intercepted 55.5 metres at 0.93% copper from surface, including 7.5 metres at 2.58% copper, while DCH-80 intercepted 65.2 metres at 0.70% copper from surface, including 31 metres at 1.23% copper. Another hole, DCH-83, in the Condori zone showed well-marked zonation of copper oxides and mixed and enriched supergene (with anomalous values in rhenium and gold).
Chmelauskas noted that the solubility results from Lourdes zone compare favourably to the oxide mineralization at the main Adriana zone that extends to depths of over 200 metres, and the…
