Oct 29, 2014 (Mark Puumala) - The following description of the Mere showing is provided by Schnieders et al. 2002 OFR6081): The host rock is predominantly equigranular hornblendite to coarse-grained, hornblende leuco and melagabbro, locally cut by reticulate leucogabbro pegmatite veins and hornblendite dikes. The pink feldspars are typically recessively weathered. The initial discovery was facilitated by a prominent gossanous face on a large outcrop knob in a relatively flat, sandy outwash plain. Weakly magnetic, fine-grained disseminated sulphides may reach 1%. Scattered clots of magnetite + epidote + secondary amphibole were also noted.

Oct 29, 2014 (Mark Puumala) - The most significant mineralization that is observed at the Mere showing occurs in a 3 x 2 metre area that containis2-3% pyrrhotite (and pentlandite), chalcopyrite, and pyrite. Sulphide mineralization consists of interstitial blebs and clots up to 0.3 centimetres in size that are concentrated within a pod of pegmatitic leucogabbro. Alteration at the showing consists of weak epidote alteration of feldspars, introduced K feldspar grains, and weak chlorite/actinolite development. Magnetite occurs locally as coarse clots interstitial to the mafic minerals. Assays of grab samples collected from the Mere showing have returned values of up to 739 ppb Pd, 231ppb Pt, 131 ppb Au, 1249 ppm Ni and 3159 ppm Cu. (McCrindle and Fingler 2001 AFRI52H12NW2003). The best assay results for samples collected from the showing by OGS in 2001 were as follows: 385.89 ppb Pd, 112.5 ppb Pt, 493 ppm Ni and 1708 ppm Cu (Schneiders et al. 2002).
May 04, 2023 (Therese Pettigrew) - The Mere showing hosts sections of gabbro, varitextured gabbro, pyroxenite, and breccia zones of heterolithic compositions. PGE mineralization occurs in association with fine- to coarse-grained pyrrhotite-chalcopyrite-pyrite blebs in 0.1-3.0% total volume. Sample A0159015 returned 717 ppb Pd, 175 ppb Pt, 152 ppb Au, 3710 ppm Cu, 1430 ppm Ni, and 78 ppm Co (Assessment report 20000019980).
