Peak Minerals Limited (Peak or the Company) to provide an update on the petrographic analysis of mineralisation from the Lady Alma Prospect within the Green Rocks Project, Western Australia. Samples from CHRCD004 and CHD005B-W1 showed the presence of an intercumulus sulphide consisting of pyrrhotite, chalcopyrite and pentlandite. The samples were sent for scanning electron microscopy (SEM) which confirmed the three-phase sulphide identified in petrography as well as minor millerite and bornite.

The intersected mineralisation provides insights into the potential grade of the system. Calculating Ni tenor is further support of a magmatic nickel-copper system. Moving Loop Electromagnetics (MLEM) is planned in May to help target the magmatic source of this mineralisation prior to drill testing.

Two samples were submitted to ALS Metallurgy for SEM analysis. A total of 5 measurements were taken from each of the two samples in a way to maximise the surface area of the sulphide present. The samples selected were the massive pyrrhotite from CHRCD004 and the stringer of chalcopyrite from CHD005B-W1.

From CHRCD004, the massive pyrrhotite from 374.4m was analysed to assess the tenor of the nickel. The initial petrography showed the presence of pentlandite as coarse grains within the pyrrhotite. The original assay sample returned 0.46% Ni and 0.17% Cu over 0.3m.

The SEM analysis identified the pentlandite grades 32.34% Ni and 5.8% Co, the chalcopyrite grades 34.46% Cu and the pyrrhotite is barren. From CHD005B-W1, the copper stringer at 827.87m graded 4.95% Cu and 0.70% Ni over 0.13m. The SEM analysis identified the chalcopyrite which grades 33.97% Cu and the bornite grading 62.4% Cu.
