Salt Creek Joint Venture
During FY2015, IGO entered into a joint venture with AngloGold Ashanti on a series of tenements on the eastern flank of the
Tropicana JV whereby the Company has the right to increase its interest in these tenements from 30% to 70% by spending
$3 million over four years. The Salt Creek Joint Venture tenements cover a significant area of the Salt Creek Complex, a
Proterozoic mafic/ultramafic intrusive complex considered to have potential for magmatic nickel-copper sulphide mineralisation.
The Salt Creek Joint Venture comprises a northern group and southern group of tenements. The southern group contains
a number of discrete magnetic features potentially representing mafic/ultramafic intrusions. These have been tested by a
program of MLEM which has identified a conductor that is planned to be followed-up with Fixed-Loop EM (FLEM) to determine if
a drill test is warranted.
The northern group covers a broad area with a complex magnetic signature, interpreted to represent multiple intrusive events.
Detailed gravity surveying followed by broad scale AC drilling is being undertaken to highlight geochemical signatures indicative
of fertile lithologies. First pass AC drilling, which is not yet completed, has identified a number of areas of elevated nickel-copper
geochemistry that are planned to be followed up with closer spaced AC drilling.
