Legend Mining (ASX:LEG) reports that the completion of the processing phase of the data from the 3D seismic survey reveals Octagonal potential at the Octagonal Prospect, within the nickel-copper Rockford Project in Western Australia.
The company engaged with HiSeis to conduct a 3D seismic survey with the aim of defining the architecture of the Octagonal Intrusive Complex (OIC), in relation to the stratigraphic package, to a depth of investigation of a minimum 1,500m below surface.
Legend reports the results highlight the ‘excellent’ correlation between the seismic dataset and the existing structural interpretation. Additionally, the 3D seismic data supports the exploration model that the OIC continues at depth below drilling completed to data.
Reverse circulation (RC) and diamond drilling completed to date, intersected multiple intervals of ‘massive’ and ‘semi-massive’, net textured, stringer, and disseminated pyrrhotite-pentlandite-chalcopyrite sulphides, associated with mafic/ultramafic intrusives of the OIC.
The company states this mineralisation demonstrates characteristics of a fertile magmatic nickel-copper sulphide system. Additionally, Octagonal sits within the same structural corridor that hosts the Nova-Bollinger and Silver Knight intrusions and nickel-copper-cobalt deposits.
Legend Mining Managing Director Mark Wilson says: “The Legend technical team is extremely pleased to see the detail of the Octagonal seismic cube which shows a strong correlation with geophysical models and structural interpretations from previous drill data.
In addition, the cube gives new information below and outside of existing drilling, all of which will assist in the ranking of holes for the diamond drill program at Octagonal scheduled for commencement in May 2023.”

In conjunction with HiSeis, Legend Mining is continuing to conduct the intensive process of interrogation, including the incorporation of existing geophysical, geological, geochemical, and structural datasets.
The geological team is currently ranking new diamond drilling targets to start in May 2023 at Octagonal.
Legend Mining is an Australian exploration company, focused on its nickel-copper Rockford Project in the Fraser Range, Western Australia, with its Joint Venture partners and shareholders Creasy Group and IGO (ASX:IGO).
