Azure Minerals drilling reveals widths and high grade copper at Cascada in Mexico Friday, July 05, 2013 by Proactive Investors
Azure Minerals (ASX: AZS) has delivered some stunning high grade drill intercepts from the new Cascada copper-gold-silver discovery located in the Mexican state of Chihuahua with widths and high grade copper including 61 metres at 4% copper equivalent.
With the Promontorio deposit, Azure already has a high grade copper equivalent resource, Cascada promises to be a second major copper deposit.
Peak grades from this drilling returned of 46.9% copper, 41.3g/t gold and 1,070g/t silver. Azure said that visual inspection of core indicates further mineralised intercepts expected in remaining holes.
The latest results are from the second batch of three holes confirm that Cascada hosts zones of high grade copper, gold and silver mineralisation contained within a wider mineralised system.
The results would seem to confirm Cascada’s potential to host a significant body of copper mineralisation.
- 56 metres at 3% CuEq including, 5 metres at 18% CuEq (10.1% Cu, 5.1g/t Au & 425g/t Ag); and
- 101 metres at 3% CuEq including, 12 metres at 14% CuEq (5.2% Cu, 11.6g/t Au & 118g/t Ag).
These intersections are along-strike continuations from similar high grade intercepts reported last week in the first Cascada holes, including: 129 metres at 2.9% CuEq, including 10 metres at 14% CuEq (10% Cu, 1.3g/t Au, 299g/t Ag).
The widths of mineralisation intersected so far and the presence of such high grade copper in three of the four holes are stunning, a word that shouldn't be overused but relevant in this case.
The Cascada mineralisation is decidedly different from that at Promontorio. Cascada appears to be a large system of widespread disseminated mineralisation whereas at Promontorio the mineralisation is constrained into narrow zones of massive and semi-massive veins.
This suggests that Cascada may have potential to host a significant quantity of copper, gold and silver mineralisation.
In a nutshell, the defined Promontorio deposit is already robust, the Cascada results should lead to an increase in the project’s overall resource base and significantly enhance the economics of the project.
