Lunnon Metals Limited (ASX: LM8) is preparing to accelerate activities at the Silver Lake-Fisher (SLF) project which forms part of the Kambalda Nickel Project (KNP) in Western Australia on the back of promising new survey results.
The results generated by the 2D seismic survey, coupled with Mincor Resources NL’s (Mincor) exciting new target generation concepts to the immediate north along strike now greatly enhance the prospectivity of the Lunnon Metals’ nickel rights acquired in April 2022.
“Lunnon Metals is delighted that the 2D seismic survey has delivered high quality targets worthy of consideration for immediate drill testing,” Managing Director, Edmund Ainscough, said.
“This outcome, coupled with exciting developments by our neighbour Mincor on the ground to the immediate north of our mineral rights area, highlights the amazing potential of the Kambalda Dome to continue to yield exciting exploration stories even after 55 years or more of operating history”.
The company has now completed the 2D survey using the “mini vibro-seis” seismic data collection method. The survey was successful with two 2D seismic lines completed on the surface of Lake Lefroy, to the immediate east of the historical Silver Lake mine and to the immediate south of the Long Operation.
In total, approximately 13.5Mt were mined historically from the Long Shaft and Silver Lake nickel mines generating over 465,500t of nickel metal1 at an average grade of 3.45% Ni.
Initial assessment of the survey results indicates:
• Excellent representation of the key prospective komatiite-basalt contact, notably shallower than expected;
• Identification of possible channel signatures (reflectors) at the komatiite-basalt contact;
• One such possible channel signature, in particular, has the potential to be the down plunge and fault-offset extension of one of the mineralized channels present at the Long Operation which were successfully mined by IGO Ltd prior to the sale of Long Operation to Mincor (namely the Long-Moran or Victor-McLeay channels); and
• Strong correlation between 3D structures interpreted by the company and breaks in the seismic reflection data, validating the company’s preliminary geological model.
This result supports the design and costing of a full 3D seismic survey using the same mini vibro-seis methodology, which will now be fast tracked. Further analysis will be conducted to refine the interpretation and target generation, however, the company has decided to start work to extend an existing causeway on Lake Lefroy to deploy a surface diamond rig. The rig will drill a series of holes up to 1,000m+ deep, to directly target these possible channel features.
The programme will also:
• collect key litho-structural data that will improve the geological control on this section;
• provide stratigraphic physical property data which will help fine tune the future 3D seismic survey; and
• serve as platforms for Down Hole Transient Electro-Magnetic (DHTEM) surveys which will seek to identify near and off hole conductive responses that may indicate the presence of nickel sulphide mineralization.
