Sipa Resources updates Enigma exploration target

THE DRILL SERGEANT: Sipa Resources (ASX: SRI) has had the Exploration Target for the Enigma copper prospect updated by Cube Consulting.

The Enigma copper prospect is situated within the company’s 100 per cent-owned Thaduna copper project in the Gascoyne Region of Western Australia.

Cube has estimated the contained copper metal at Enigma to be in the region of 84,000 to 210,000 tonnes, within 42 to 69 million tonnes of mineralisation grading between 0.2 per cent and 0.3 per cent copper at a 0.1 per cent copper cut‐off.

“The major significance of the Exploration Target is that it quantifies the amount of copper metal within what is a very large geochemical anomaly, which is at least four kilometres long by 1.5 kilometres wide – and which is presently not constrained by drilling to the northeast and west,” Sipa Resources said in its ASX announcement.

“Within the Target there are 16 drill holes with greater than 10 per cent ‐ metres of copper –  that is, intersections like 9 metres at 4 per cent copper and 12 metres at 1 per cent copper.

“Some of these intersections are within gossans, interpreted as representing oxidized semimassive to massive sulphides, including copper sulphides.”

Sipa indicated it considers these intersections indicate potential for zones within the exploration target to host bodies of secondary mineralisation.

It does not however, consider this to be the real significance of the amount of copper in the Target.

The company has said it has interpreted the amount of secondary copper to indicate proximity to a large source, or sources, of primary copper sulphide mineralisation.

A drill program has been scheduled to commence later this month and some 25,000m of Aircore, 10,000m of RC and 2,500m of diamond core is to be conducted at a cost of around $3 million.

The company expects the program will take around three to five 5 months to complete.

The Aircore is designed to better define the controlling structures to secondary copper, and gossan mineralisation as well as explore to a greater depth in the 10 kilometre long corridor of ‘Enigma Host Rocks’ easterly and westerly of the Enigma Exploration Target boundaries.

The RC and diamond core drilling will test at depth the mineralised structures and gossans.
