Legend Mining Limited announce the completion of the processing and modelling phase of the data from the 3D seismic survey over a 6.5km2 area at the Mawson prospect within the Rockford Project, Fraser Range, Western Australia. HiSeis field teams carried out the survey data collection in December 2021. Processing and modelling have now been completed with Mr. Barry Bourne from Terra Resources as external consultant.

A comprehensive technical discussion is contained in the body of this announcement. HiSeis has completed the 3D seismic survey data processing phase for the Mawson Prospect. Time and depth modelling has been completed, with delivery of the final 3D cube.

The aim of the survey was to define the architecture of the Mawson intrusion in relation to the stratigraphic package, to a depth of investigation of a minimum 1,000m below surface across a 6.5km2 area. In addition, a more detailed survey on the western side of the survey area was designed to test for a direct detection signature of Ni-Cu-Co sulphide accumulations at the Mawson discovery zone, given the shallow nature of mineralisation (<250m below surface). The seismic signature of the Mawson discovery zone is clearly evident and importantly appears to replicate in an offset position below the discovery zone, presenting a compelling diamond drill target.
