Jan 13, 2022 (Sheree Hinz) - Volcanic packages in the area range from mafic to intermediate volcanics. Both felsic and mafic intrusives were noted typically ranging from porphyries, diorite, diabase and gabbros. Diabase dykes appear to strike northwest. Several faults were noted within some of the deeper drill holes at the MATHU Project.

Jan 13, 2022 (Sheree Hinz) - A Beep Mat 8 survey led to the discovery of MATHU showing as over 20 conductors were located and several of them trenched. Anomalous Au, Ag, Co, Pd, and Pt values have been noted within surface sampling. At discovery, the MATHU showing consists of two gossanous approximately 1-meter wide lenses of sulphides less than a meter apart. The sulphides strike approximately 126/306 degrees. Near surface the sulphides are heavily weathered and gossanous. Main sulphide minerals appear to be pentlandite, pyrrhotite, chalcopyrite. In samples low in sulphide content, trace amounts of chalcopyrite have weathered to bornite color. In addition, in seams low in sulphide content, dendritic flakes or smudges of native copper were also noted. Grab sample MT-GRAB2015-14 contained 2.65% Ni, 0.847% Cu, 0.061% Co, 0.18g/t Pt, 0.23g/t Pd, 0.16 g/t Au. The 2016 drill program targeted the MATHU showing, and two holes targeted directly underneath/down dip of the showing. GM-16-02 intercepted 3.37 meters (from 81.93m to 85.30m) of 1.3% Ni and 1.57% Cu approximately 60 meters below surface. GM-16-03 intercepted 2.84 meters (from 115.30m to 118.14m) of 0.93% Ni and 1.45% Cu and 1.5 meters (from 121.5m to 123.00m) of 0.34% Ni and 0.45% Cu approximately 100 meters below surface. GM-16-04 and GM-16-05 targeted along strike of the MATHU Showing approximately 70 meters northwest of GM-16-02, GM-16-03. GM-16-04 intercepted 5.4 meters (from 72.6m to 78.0m) of 0.9% Ni and 0.63% Cu approximately 50 meters below surface. The Ni-Cu sulphides encountered during drilling appear to be fracture-filling ranging from semi-massive to net textured, to stringer sulphides. Mineralization was intercepted to an approximate depth of 100 meters directly under the MATHU Showing and remains open at depth.
