THE DRILL SERGEANT: Azure Minerals (ASX: AZS) completed the first drilling program on the company’s 100 per cent-owned Sara Alicia gold-cobalt project, located in the northern Mexican state of Sonora.
Azure Minerals said the reconnaissance drilling was designed to test a zone of high-grade gold and cobalt mineralisation, which was historically exploited by small-scale underground mining in the 1930s.
The area was further outlined by Azure’s sampling of surface outcrop and underground exposures which returned high-grades up to maximum values of 39 grams per tonne gold and 7 per cent cobalt.
The company explained the initial drilling program comprised six holes of diamond core 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 sulphides,” Azure Minerals said in its ASX announcement.
“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 analyses respectively.
“Due to a very busy northern hemisphere field season, the turnaround time for sample analysis in Vancouver is currently between four and six weeks.
“Assay results for the Sara Alicia holes are expected between late November and early December.”
