Azure Minerals Ltd has completed its first drilling programme on its 100%-owned Sara Alicia gold-cobalt project, located in the northern Mexican state of Sonora.
The reconnaissance drilling was designed to test the zone for high grade gold and cobalt mineralisation, which was historically exploited by small-scale underground mining in the 1930s, and further outlined by Azure’s sampling of surface outcrop and underground exposures which returned high grades up to maximum values of 39 g/t gold and 7% cobalt.
This initial drilling programme comprised six holes totalling 480 m of diamond core. The drilling was designed to test around the old mine workings and beneath the outcropping gold and cobalt mineralisation to determine potential grade, width and orientation of the mineralised zone.
Core logging identified carbonate rocks intruded by a granodiorite porphyry, causing strong alteration and mineralising reactions in the limestones, forming a skarn horizon enriched with garnets, magnetite and sulfides.
Each drill hole was sampled in its entirety and dispatched to the Bureau Veritas laboratories in Hermosillo, Mexico, and Vancouver, Canada for precious metal and base metal analysis respectively. Due to a very busy northern hemisphere field season, the turnaround time for sample analysis in Vancouver is currently 4 - 6 weeks. Assay results for the Sara Alicia holes are expected between late November and early December.
