Legend Mining has uncovered a significant nickel-copper discovery at the Rockford project in the Fraser Range, Western Australia.
The result from the third diamond drill hole at area D, which has been renamed Mawson, was 14.9 metres at 1.07 per cent nickel, 0.75 per cent copper and 0.06 per cent cobalt from 115 metres.
Legend managing director Mark Wilson said Mawson had distinct differences from other sulphides in the area such as Nova, Silver Knight and Octagonal, due to its stratigraphic rock layers.
He said the discovery is an outstanding exploration success for the company and a “watershed moment” for the Fraser Range and Legend’s stakeholders.
“The 2.1-metre-high grade intercept within a 14.9 metre sulphide zone within a 70-metre disseminated sulphide halo has all the hallmarks of a large mineralised system,” Wilson said.
“Mawson lies within a 16 kilometre by 6-kilometre mag feature within a distinctly different stratigraphic package of rocks from the other known Fraser Range occurrences of massive sulphides.”
Legend has been working with Perth-based exploration company, the Creasy Group, to explore the Rockford area which it formed a joint venture with during September 2015.
Together, the two companies have completed project-wide aeromagnetic data interpretation, 3D inversion modelling, electromagnetic surveys covering 245 square kilometres and 27 target areas and drilling 10 reverse circulation (RC) drill holes and four diamond drill holes.
These results unearthed the prospective Mawson discovery and five other priority prospects which include magmatic nickel-copper sulphide targets and volcanogenic massive sulphide (VMS) style zing-copper-silver targets.
Looking ahead, Legend and Creasy Group will complete structural logging of the third diamond drill hole to plan for follow up drilling, the determine the extent of the copper-nickel mineralisation.
