Legend Mining Ltd (ASX:LEG) continues to advance exploration at the highly prospective Rockford project, located in the globally renowned Fraser Range district of Western Australia.
The project covers an area of 2,792 square kilometres.
The majority of the project comprising seven contiguous granted exploration licences is the subject of a joint venture between Legend (70%, operator) and Creasy Group (30%).
Creasy Group is affiliated with legendary prospector Mark Creasy, who owned an interest in arguably one of Australia’s best discoveries in recent times – the Nova Bollinger nickel-copper project in the Fraser Range.
Importance of latest drilling
Legend recently wrapped up a diamond and reverse circulation drilling program.
Final assay results showed the tenor of nickel and copper values from two sulphide bearing pyroxenitic units were consistent with field observations and drill core logging.
Several intervals with high MgO (18-27%) values and up to 0.16% nickel in the two diamond holes are of particular interest, as they are indicative of mafic/ultramafic lithologies.
The true significance of these intervals and other assay results will not be fully understood until integrated with the petrology results which are expected by the end of September 2017.
Mark Wilson, managing director, commented:
"We are looking forward to the petrology results to confirm we have intersected mafic/ultramafic intrusions into sulphur rich metasediments at Area N.
"This is a geological setting consistent with Nova style nickel-copper orebodies.
"We are also currently conducting innovative low frequency fixed loop EM surveys at Area N to assist in identifying the next round of diamond drill targets at this location."
Future activities
- Complete assessment and evaluation of drill core assay results in conjunction with results from petrology samples;
- Low frequency FLTEM over conductor N1 aimed at defining “hot spots” along the entire 800 metre strike length of the conductor;
- Low frequency DHTEM surveying in drillhole RKDD003 (N1) to better define the parameters of the very strong >30,000S offhole feature;
- Aircore drill traverses over nine untested bedrock conductors (D3, E1, J1-2, M1, N3, Q1, S1, U1) to provide lithogeochemical data and information on regolith character and depth of cover; and
- MLTEM survey over Area V target.
