Gawler Craton, South Australia

 

Oodnadatta Project

Integra is also progressing the exploration of high-risk / high reward exploration targets at its Oodnadatta IOCG (Iron Oxide Copper Gold) Project in the Gawler Craton, South Australia, in conjunction with farm-in partner Barrick Gold of Australia Ltd ("Barrick Gold").

The Barrick Gold farm-in marked the culmination of work by Integra to advance the Oodnadatta Project, located 400 kilometres north northwest of Olympic Dam within the major G2 Corridor - the same Gawler Craton margin structure interpreted from aeromagnetics and gravity data that hosts the Olympic Dam copper-uranium-gold and Mount Gunson copper deposits.

During the first half of 2007, Barrick Gold identified several anomalies, including six targets, commencing drilling on at least four of the targets in the latter part of the year.

Barrick Gold’s exploration program follows a diamond drilling program conducted by Integra at the Borthanna target during 2006.

Integra’s program was based on magnetic and gravity data modelling which revealed several discrete gravity anomalies on the margins of the Allandale Complex, located at the intersection of the northwest trending G2 Corridor and a regional northeast trending structural zone.

Integra aimed to penetrate the top of the gravity body #1.  Due to technical difficulties encountered and the subsequent farm-in by Barrick Gold, the drilling program was delayed.

Subject to drilling conditions and performance, the Joint Venture plans to have all four targets drill tested by the end of 2008.  The target mineralisation is Iron-Oxide Copper Gold (IOCG) style similar to other deposits in the Gawler Craton such as Olympic Dam, Prominent Hill and the more recent Carrapateena discovery.
