Legend Mining continues “evolution of the Mawson story” with more massive sulphides intersected

Legend Mining Limited (ASX:LEG) has uncovered more semi-massive and massive sulphides while extending the mineralised intrusion footprint at the Mawson nickel-copper-cobalt prospect within the flagship Rockford Project on Western Australia’s Fraser Range. The explorer is further investigating Mawson’s strong prospectivity with step-out diamond drilling and through down-hole transient electromagnetic (DHTEM) surveys over a suite of drill holes. Promisingly, drill hole RKDD053 returned an 11-metre intercept grading 1.02% nickel, 0.54% copper and 0.09% cobalt from 132 metres and within this was 2.94 metres at 1.48% nickel, 0.49% copper and 0.12% cobalt from 136 metres. Meanwhile, Legend’s diamond drilling campaign continues to extend the mineralised intrusion footprint at Mawson, while DHTEM work is ongoing to identify multiple targets. Mineralised footprint “continues to grow” Legend Mining managing director Mark Wilson said: “The significance of results from hole 53 is an 11-metre intercept of more than 1% nickel and the presence of massive sulphides several hundred metres from the Mawson discovery zone. “Meanwhile, the geology and geophysics (DHTEM conductors) from the next nine holes reported in this announcement continues to grow the mineralised footprint of the intrusion — the evolution of the Mawson story.” Exploration highlights Since Legend provided an update on exploration at the Mawson prospect last month, the ASX-lister has kicked off or completed nine diamond drill holes, with two drilling rigs working in double shifts to explore the area. One of the best results came from a new diamond drill hole designed to test an off-hole conductor identified above a previously drilled hole. As wells as the 11-metre intersection, hole RKDD053 also returned 2 metres at 1.13% nickel, 0.96% copper and 0.09% cobalt from 114.7 metres. Nickel-copper sulphide mineralisation from RKDD053 from 135-140 metres. Promisingly, DHTEM surveying over the hole has identified two conductors, interpreted to be extensions to the mineralisation, suggesting this zone will host more massive sulphide mineralisation. Broadly speaking, the latest holes drilled during Legend’s exploration program were planned in correlation with previous diamond intersections. DHTEM work across the new drill holes is either slated to begin imminently or has already been carried out, with results pending.    In addition, three of the latest drill holes were along a newly identified intrusion, situated 2 kilometres south of the Mawson prospect, and intersected a large series of mafic and ultramafic intrusions. The intrusion was first discovered in hole RKRC041 and reported to the ASX back in January. Although minor mineralisation was encountered, Legend identified olivine-rich harzburgite and fractionated mafic suites, suggesting this new intrusion displays the key components to be fertile for nickel-copper sulphide mineralisation. A DHTEM survey is planned to take place over the three new diamond holes drilled along the intrusion, with additional drilling planned once assays and surveying results come in. Next steps As Legend continues to investigate Mawson’s prospectivity, diamond drilling continues systematically over the prospect. Currently, two diamond rigs are active at the WA base metals play, working across priority target areas. Additionally, Legend plans to undertake DHTEM work across all completed diamond drill holes at Mawson to further evaluate their potential. Ultimately, the ASX lister hopes to integrate each of the diamond, reverse circulation, geochemical and geophysical datasets from the prospect to advance a 3D emplacement model, with new constrained gravity and magnetic inversions ongoing. The company anticipates releasing an updated 3D model in the coming weeks. Legend will provide further updates on work at its flagship prospect as new results become available.
