Legend Mining Limited (ASX: LEG) has intersected further massive nickel-copper sulphides in drill hole RKDD013 from the Mawson prospect within the Rockford Project at Fraser Range in Western Australia.
Managing Director, Mark Wilson, said the results have also extended the known mineralisation at Mawson.
Extending this massive nickel copper mineralisation 20m south with another wide intercept is an exciting development in the Mawson story,” Mr Wilson said.
It vindicates Legend’s strategy of step out drilling of geological and geophysical targets generated from previous drill holes.”
Legend has now completed diamond drill hole RKDD012 while RKDD013 is nearing completion at 290m depth at Mawson.
The drill holes were testing a combination of downhole electromagnetic (DHTEM) conductors and interpreted extensions to sulphide mineralisation from previous drill holes.
RKDD013 intersected 13.5m of massive nickel-copper sulphide, while RKDD012 intersected a broad interval of disseminated sulphides similar to that seen in the upper part of RKDD007.
Hole RKDD013 was designed to test a strong 50,000-60,000S DHTEM conductor identified in RKDD010 and also test for extensions to the sulphide mineralisation intersected in drill hole. The hole intersected a 12m interval of massive nickel-copper sulphide mineralisation from 239.2m and a further 1.5m from 257.5m downhole (see Figures 2 & 3).
RKDD013 has extended the strike length of massive nickel-copper sulphide 20m to the south with significant intersections returned in drill holes RKDD008, RKDD011 along with the discovery intercept in RKDD007. The sulphide mineralisation in RKDD013 is hosted in a mafic intrusion and is open to the south, northeast and east.
DHTEM surveying with multiple loop configurations is planned for RKDD013 to test for southerly extensions to the mineralisation and to assist future drill hole design. Structural logging is planned for a future date, depending on the consultant’s availability. RKDD013 will be sampled immediately and submitted for assay with results expected in 2-3 weeks.
Drill hole RKDD012 was drilled to test the northern extension of mineralisation intersected in RKDD007. The hole intersected a broad (42.7m) interval of disseminated sulphide (pyrrhotite- chalcopyrite-pentlandite) associated with olivine gabbronorite and ultramafic from 103.2m downhole.
Mr Wilson said this interval correlates with the upper halo of disseminated sulphide intersected in RKDD007, however the higher-grade interval in RKDD007 was not intersected at depth.
Structural logging of this hole indicates that stratigraphy has changed strike sharply toward the northeast and further assessment of the geology and geophysics in this area is required to fully evaluate the potential.
