Azure Minerals intersects 70m of Mexican copper

/in /by

THE DRILL SERGEANT: Azure Minerals (ASX: AZS) has received all assay results from recently-completed drilling at the company’s Promontorio project, located in the Mexican state of Chihuahua.

The results include a 70 metre intersection of copper mineralisation at Cascada as well as copper intersections at a newly identified prospect – Risco Dorado.

The 70m intersect at the Cascada prospect came from the last hole of the program, situated about 200m of the Promontorio deposit where historic exploration had predominantly focused on testing for gold and silver, ignoring copper.

Azure’s drill hole was designed to follow historical drilling that returned moderate gold grades, and to test for copper potential at depth.

In the first 40m of the hole, two zones returned gold intersections of:

–    6.95 metres at 0.6 grams per tonne gold and 12 metres at 1.1 grams per tonne gold with a highest grade of 3.6 grams per tonne gold.
 
At a depth of 41.9m, the hole entered a zone of copper sulphide mineralisation, which extended over a downhole length of 70m hosting disseminated, veined and massive copper sulphide mineralisation in varying amounts throughout the entire mineralised interval.

This zone returned mineralised intercepts at various cut-off grades:

At 0.2 per cent copper cut-off grade

–    70.0m at 2.7 per cent copper equivalent (1.6 per cent copper, 0.9g/t gold and 35g/t silver) from 41.9m;

At 0.5 per cent copper cut-off grade

–    35.9m at 4.8 per cent copper equivalent (2.9 per cent copper, 1.5g/t gold and 65g/t silver) from 76.0m; and

At 1 per cent copper cut-off grade

–    11.25m at 10.5 per cent copper equivalent (7 per cent copper, 2.3g/t gold and 147g/t silver) from 80.65m; and

–    7.25m at 3.8 per cent copper equivalent (2 per cent copper, 1.9g/t gold and 32g/t silver) from 101.75m

Azure said this drill intercept was an exciting development  as it opens up the possibility of another copper deposit located within a short distance of Promontorio.

“Good widths of high-grade copper, gold and silver mineralisation from areas untested by previous exploration confirm potential to increase the project’s resource base,” Azure Minerals managing director Tony Rovira said in the company’s announcement to the Australian Securities Exchange.

“The highlights of the drilling are the intersections we made as part of the wider exploration program.

“The exceptional copper intercept at Cascada is Azure’s best to date within the whole project area, and indicates strong potential for another significant body of copper mineralisation adjacent to Promontorio.

“Furthermore, drill intercepts at the newly named Risco Dorado (Golden Cliff) prospect are promising and augur well for further exploration successes in that area.”
