Legend Mining Limited (Legend) announced the maiden Mineral Resource Estimate (MRE) for the Mawson Deposit within the Rockford Project, Fraser Range, Western Australia. The Rockford Project is located within the highly prospective Fraser Range district of Western Australia, with tenure covering a total area of 2,994km2 and comprising 14 granted exploration licences. Located 300km east of Kalgoorlie, the Rockford Project is serviced by excellent infrastructure including the Trans- Australia Railway and gas pipeline to the Tropicana Gold Mine.

The Mawson Ni-Cu-Co Deposit is within E28/2188 and E28/2189, which is under a Joint Venture between Legend (70%) and the Creasy Group, through Rockford Metals Pty Ltd. (30%). This maiden Mineral Resource Estimate was completed by Ashmore Advisory Pty Ltd. (Ashmore). The MRE is based on 26 drillholes completed between 2019 and 2021, which consisted of 24 diamond core (DD) and 2 reverse circulation (RC) for 8,938m.

All drillholes were assayed where they intersected mineralisation. The mineralisation was modelled from a depth of 65m to 305m below surface. The drillhole spacing is predominantly 20m by 20m across the discovery zone, broadening to approximately 50m by 100m over the remaining areas.

Results of the independent Minerals Resource Estimate by Ashmore for Mawson are tabled in the Statement of Mineral Resources. The Mineral Resource Estimate was classified as Indicated and Inferred Mineral Resource based on data quality, sample spacing, and lode continuity. The Indicated Mineral Resource was defined within areas of close spaced drilling of less than 25m by 25m, and where the continuity and predictability of the mineralised units was reasonable.

The Inferred Mineral Resource was assigned to areas where drillhole spacing was greater than 25m by 25m and less than 50m by 50m; where small, isolated pods of mineralisation occur outside the main mineralised zones, and to geologically complex zones. The Mawson Nickel-Copper-Cobalt Deposit shows good continuity of the main mineralised zones which allowed the drillhole intersections to be modelled into coherent, geologically robust domains. Consistency is evident in the thickness of the structure, and the distribution of grade appears to be reasonable down plunge of the main zones.

The extrapolation of the lodes along strike and down-dip has been limited to a distance equal to the previous section drill spacing or to 50m. Further drilling along strike or down-dip within the Mawson area may define extensions to known mineralization or new zones of mineralization. There is an opportunity to increase the level of confidence in the estimate by conducting infill drilling.
