Dec 19, 2013 (Therese Pettigrew) - Sheared intermediate to felsic metavolcanics and in sheared and fractured diorite to gabbro or feldspar and quartz-feldspar porphyry bodies emplaced within intermediate to felsic metavolcanics. All rocks within or adjacent to shear zones are schistose and have been variably sericitized, silicified, albitized, epidotized, hematized and sulphidized.

Apr 28, 2016 (Therese Pettigrew) - The Moss Lake Gold Deposit is a structurally controlled gold deposit within the greenstone terrain of the Archean Superior Province. Mineralization is localized where the major NE-trending Wawiag Fault Zone cuts a dioritic to granodioritic intrusive complex. The deposit is defined by a series of anastomosing centimeter- to meter-scale NE-trending shear zones carrying higher-grade gold mineralization, and lower-grade gold mineralization associated with more brittle-style deformation and veining in the intrusive rock mass between the shear zones. Mineralization is associated with pyritic sericitic and chloritic alteration and millimeter- to centimeter-scale irregular quartz-carbonate veinlets (Goldshore Resources news release Nov 15, 2022). Significant intersections from the 2008 drill program include the following: ML-08-02: 2.73 gpt Au over 15.8 m (81.4-97.2 m); ML-08-06: 2.06 gpt Au over 21 m (209.7-230.7m); ML-08-07: 3.64 gpt Au over 18.3 m (176.8-195.1 m); ML-08-08: 2.73 gpt Au over 13.7 m (271.9-285.6 m); ML-08-13: 2.37 gpt Au over 16.5 m (189.8-206.3 m); ML-08-15: 3.26 gpt Au over 20.4 m (77.7-98.1 m). Gold mineralization in the Moss Lake deposit, between Snodgrass Lake and Span Lake, occurs in sheared intermediate to felsic metavolcanic rocks and in sheared and fractured diorite to gabbro or feldspar and quartz-feldspar porphyry bodies emplaced within intermediate to felsic metavolcanic rocks of the CFB. At the Moss Lake deposit, the diorite to gabbro bodies, the quartz-feldspar and feldspar porphyries, and the felsic metavolcanics are all cut by the Snodgrass Shear Zone, a steeply dipping ductile shear zone up to 4.5 m wide and striking NE (N040) to ENE (N060-N075). Other anomalous gold values were also obtained from fractured diorite, sheared feldspar porphyry, and a moderately deformed, pink-weathering quartz-amphibole-phyric intrusion. This relatively late porphyry dyke or sill intrudes the diorite and felsic schist (Richard et al., 2013). Goldshore Resources' DDH MMD-22-051 returned 1.02 g/t Au over 192.75m from 94.45 m depth, including 1.49 g/t Au over 62 m and 1.29 g/t Au over 48.7 m (Goldshore Resources news release Sept 29, 2022).
