Power Metallic Starts Metallurgical Testing with SGS; 14 Weeks
“Metallurgical Testing is one of the key steps mining companies take to derisk development of mining projects. It is also a necessary step for NI 43-101 reporting on the resource and its economic potential. While we have no immediate plans to produce a NI- 43-101 resource report the results of this study will enable independent bank, company and industry analysts to utilize the appropriate resource recovery numbers while developing economic valuations on the Nisk project. In this respect we are following the path well established by projects like Filo and Great Bear, who both posted assays and azimuths for their exploration results and allowed the analysts to speak to the economic potential of these projects.” Commented Power Metallic CEO Terry Lynch
Power Metallic carried out a competitive bid process for carrying out the metallurgical studies and has awarded the contract to SGS Canada Inc. based on their extensive experience with flotation metallurgical testing. Compositing of the samples, and flotation studies will be conducted in
Work to date has shown that the copper mineralization is contained within coarse grained chalcopyrite and cubanite, both which should respond well to conventional sulphide concentration methods. Overall, the character of the mineralization suggests good recoveries of copper sulphides, and these initial metallurgical tests will determine the recovery potential of the PGEs, Au, Ag, and Ni., which are expected to report within a conventional sulphide concentrate.
The Lion deposit has two zones of mineralization defined by drilling, consisting of a High-Grade zone (HG) and a lower grade Hanging-wall Zone ((LG). Current understanding is that the vast majority of the metal value in the deposit is contained within the High-Grade zone, consisting of semi-massive to massive copper sulphide mineralization. The chosen rejects consist of the two zones, the massive to semi-massive sulphides HG, and the LG disseminated and veined structural hanging-wall to the HG.
Power Metallic compiled a series of drill core reject material from the Lion deposit. The sample rejects were chosen to be spatially representative of the known mineralization across strike and down plunge within the deposit. The HG is represented by 103 samples from 15 drill holes and the LG is represented by 99 samples from 10 drill holes (Figure 1).
Each zone of collected core rejects represented approximately 300 kg of sample material which were hand delivered to the SGS laboratory in
The HG and the LG will each have 25 kg extracted from the 75 kg composites to form a Blended Composite, resulting in three (3) separate 50 kg composites for initial analyses and flotation testing. The 50/50 ratio of HG to LG weighting for the Blended composite is based on current estimates of modelled volumes for the two Lion deposit types. Each of the three composites will go through complete metallurgical testing for determining any variability for recovery of the six (6) principal metals (Cu, Pd, Pt, Au, Ag, Ni) for each zone and for the Blended composite. Additional testing may be done for rare earth minerals associated with this polymetallic deposit type (Os, Ir, Rh, Ru, other) if initial mineralogy suggests potential economic concentration.
The metallurgical tests are anticipated to take approximately 14 weeks to complete. Power Metallic will divulge results of the testing as soon as practical, but final reporting of results is not expected before January 2026.
