The Melrose Project consists of twelve Exploration Licences (EL08/3183, EL08/3184, EL08/3188, EL08/3210, EL08/3219, EL08/3244, EL08/3280, ELA08/3344, ELA08/3351, ELA47/4362, ELA47/4414 and ELA47/4529) and two Prospecting Licences, and covers a total area of 371km2. It is located approximately 105km south of the mining town of Pannawonica on the border of the Ashburton and West Pilbara Mineral Fields.
The Melrose Project is situated on the same regional structure reported as the main source of gold mineralisation at the Paulsens Gold Mine and Mt Olympus Gold Mine, similar to the Company’s Saltwater Project.
The structural corridors that control the mineralisation at Paulsens appear to continue into Aruma’s Melrose Project area. The Project was pegged in 2020 and multispectral and Aster data with radar has been used to define anomalous areas. This information along with historical data and structural analysis will be used to define targets for drilling.
The Paulsens Deposit was discovered and mined in the early 1930s, and was then called the Melrose Mine. It is situated in a +3 million ounce gold camp and most production has come from multiple lodes at the Paulsen Mine.
Modern evaluation and mining of the Paulsens mine by NuStar Mining Corporation commenced in May 2004 and the Paulsens process plant poured the first bar in June 2005. In July 2010, Northern Star Resources took over the mine and successfully mined it until late 2017, producing up to 100,000 ounces of gold per year through both existing and new ore shoots.
Since 2017 Northern Star has relinquished areas in the Paulsens district following initial exploration, and these areas represent the ground that Aruma has appraised, using its “gold-in-sediment” exploration model to seek stratigraphic repetitions in favourable structures associated with the Nanjilgardy Fault.
Most of the reported historic drilling and sampling was conducted on east-west traverses at a spacing that Aruma believes has left windows of opportunity for the discovery of further gold mineralisation.
