Oct 31, 2019 (Therese Pettigrew) - The Missing Link Extension occurrence lies within the extreme north central portion of the main Beardmore-Geraldton belt just south of the eastern trace of the Paint Lake fault. It has been suggested by both Fekete (1990) of Freewest Resources Inc. and OGS Staff J. Mason and G. White that an east northeasterly splay of this prominent fault traverses the property (Mason and White, 1994).

Oct 31, 2019 (Therese Pettigrew) - Variations in the degree and type of alteration and mineralization give this shear zone a banded appearance. Four distinct subzones were recognized: 1a, 1b, 1c and 1d. Subzone 1a consists of· weakly sheared, resistant andesite with weak to moderate chlorite/carbonate alteration. It is generally a pale green colour. The best result obtained from this subzone is 0.013 opt Au/0.9 m. Subzone 1b consists of moderately sheared andesite with weak to moderate chlorite/carbonate/silica aIteration which gives the rock a banded, bleached to rusty appearance. It averages about 4.0 m wide. The best assay for this subzone unit is 0.11 opt Au/1.0 m. This value is unusually high and is probably related to the fault that cross-cuts the shear zone. Subzone 1c is very similar to 1b in regard to alteration and appearance but is characterized by occasional quartz stringers with a general strike of 060°, conjugate to the direction of shearing. These stringers never exceed a width of 5.0 cm and are often pitted where ankerite or other carbonates have weathered out. Minor disseminated sulphides were noted in this subzone. Up to 0.52 opt Au/0.4 m was obtained from this subzone. Subzone 1d consists of a stockwork of quartz veinlets in a very sheared, altered and mineralized andesite. Knobs of intense silica alteration containing up to 20% sulphide poke through at very rusty, weathered intervals. Fine, disseminated arsenopyrite, pyrite and chalcopyrite are the main sulphide minerals. intense sericite alteration and oxidation occur in the rusty intervals. The quartz veins within this ·subzone are contorted into minor drag-folds. The abundance of quartz increases towards the fold hinge where it occurs in knobs bearing up to 15% chalcopyrite in coarse blebs. The best assays from this subzone are from grab samples of the silica/sulphide, 0.144 opt Au, and quartz/chalcopyrite, 0.2 opt Au, knobs in the fold hinge. This altered, sulphide-rich shear zone is also exposed in a smaller 3 m by 20 m long "north trench" approximately 120 m northeast of the main trench. The highest assay was obtained over the most intensely gossaned area and returned a value of 0.018 opt Au across 1. 3 m (Assessment report 42E11NW0071)
