INDEPENDENCE GROUP NL SUSTAINABILITY REPORT 2018

LAKE MACKAY AND RAPTOR PROJECTS The Lake Mackay joint venture with Prodigy Gold (formerly ABM Resources) covers approximately 7,600 square kilometres of granted exploration licences and a further, approximately, 5,200 square kilometres of licence applications. The Lake Mackay Project area is 400km west-north-west of Alice Springs. The project is within the Great Sandy Desert Bioregion, which is comprised predominantly of semi-arid sand plains and sand dunes. It is named after Lake Mackay, a vast saline lake that straddles the border of Western Australia and Northern Territory, and is the fourth-largest lake in Australia, providing an important habitat for birds following flooding. While IGO’s exploration activities are not close to the lake, our practices are targeted at minimising impacts across our entire tenure. Exploration at Lake Mackay is at an early stage and, until recently, has been limited to a single tenement. Work programs during FY18 included diamond drilling at the Grapple Prospect, where reverse circulation drilling in FY17 led to the discovery of copper-gold (cobalt-zinc-lead-silver) mineralisation. The diamond drilling in FY18 intersected the best mineralisation discovered to-date. Elsewhere, ongoing regional soil sampling is delivering encouraging polymetallic geochemical anomalies that require follow-up in FY19. In addition, ongoing regional Spectrem airborne electromagnetic (EM) surveys are delivering anomalies for ground EM follow-up and drilling. The Raptor Project is a new belt-scale exploration initiative targeting nickel and copper along the Willowra Gravity Ridge in the Northern Territory. Tenement applications were lodged in FY18 and regional aeromagnetic and radiometric surveys are planned for FY19. Both projects fall on land that is primarily within areas covered by the Aboriginal Land Rights (NT) Act 2006 and access by explorers is covered under a Deed for Exploration with the Central Land Council. All work programs must be submitted to the Central Land Council for approval and meetings are held with Traditional Owners to discuss the proposed activities. Sacred site clearance surveys are also completed by the Central Land Council prior to any on-ground exploration being undertaken. IGO has been negotiating with the Central Land Council to enable access to the Lake Mackay tenements, reaching agreement in September 2017. Discussions will begin in FY19 regarding the recently acquired Raptor Project and we hope to sign an agreement permitting on-ground exploration in FY20. NORTHERN TERRITORY LAKE MACKAY PROJECT IGO 70% RAPTOR PROJECT IGO 100% SALT CREEK PROJECT IGO’s Salt Creek Project is a joint venture with AngloGold Ashanti and comprises a reverse joint venture on tenements that were previously part of IGO’s Tropicana Operation joint venture with AngloGold Ashanti. IGO has earned a 70% interest in the project through exploration expenditure and will increase that interest through further expenditure. The exploration area is approximately 220km north-east of Kalgoorlie in the Great Victoria Desert. IGO is principally exploring the Salt Creek Project for magmatic nickel- copper sulphide deposits similar in style to the Nova- Bollinger deposits. IGO’s activities over the past year have comprised of a combination of RC and diamond drilling and electromagnetic surveys to systematically test the large tenement package and define the areas of greatest prospectivity. Several areas that were tested during the past 12 months were found to be of low prospectivity, and as a result, approximately 60% of the Salt Creek Project has been relinquished. The retained tenements are still considered prospective for nickel, copper and gold, and selected targets will be followed up in the coming 12-month period. The south-western portion of the Salt Creek Project's tenure is subject to the Environment Protection and Biodiversity Conservation (EPBC) Act 1999 as a 'referral area'. Exploration activities within the area are classified as a ‘controlled action’ and require adherence to a conservation management plan. The plan has been developed by AngloGold Ashanti on behalf of the Salt Creek Project in consultation with the (former) Department of Parks and Wildlife to mitigate the potential impacts from exploration activities within the referral area.
