Legend Mining Ltd (ASX:LEG) has completed gathering data for its 3D seismic survey at Mawson prospect within the Rockford Project, Fraser Range, Western Australia.
The company commissioned the survey to define the architecture of the Mawson intrusion over the area. The investigation boundary is a minimum of 1000 metres below surface across a 6.5 square kilometre area.
This survey consisted of 6,000 vibe truck soundings. The seismic response to each sounding was recorded by geophone receivers at 8,300 points across the survey area.
HiSeis field teams have been working on the survey over the past six weeks with Barry Bourne from Terra Resources consulting.
The company is now processing the survey data and final results are expected by February 2022.
Legend has plans for a more detailed survey on the western side of the survey area to test for nickel, copper and cobalt sulphide accumulations at the Mawson discovery zone, given the shallow nature of mineralisation, which is no more than 250 metres below surface.
Plans for the new year
Legend has now finalised its field activities for 2021.
Once it has the final assay results from diamond and aircore drilling across Mawson, the company will thoroughly examine existing geophysical, geological, geochemical and structural datasets.
The grand plan is to define and rank new diamond drilling targets for the 2022 field season – this is expected to kick off in March.
“We are pleased that this data collection phase of the survey was completed on schedule before the Christmas break in field activities this year,” Legend managing director Mark Wilson said.
“The final results of the survey will provide further clarity on structural interpretations within the current drilling envelope including the massive sulphide and associated mineralisation at the Mawson discovery zone. In addition, the results will also provide structural detail around the periphery of and below the drilling envelope.”
“We expect quality drill targets for diamond drilling in 2022 to be the ultimate outcome of this survey.”
