09/14/2020 (T Pettigrew) - The property is underlain for the most part, by mafic volcanic flows and tuffs with thin interbedded felsic pyroclastic units (Assessment report 52C16SE0008).

09/14/2020 (T Pettigrew) - Work by prospectors in 1988 located the Main and West Showings. These showings consist of two parallel narrow 0.5-1 m wide quartz vein/shear zone systems with pyrite-chalcopyrite mineralization within mafic metavolcanic tuffs and flows approximately 25 Metres apart. These systems contain anomalous and ore grade Au and Cu intersections over significant widths from grab and channel sampling up to 3.276 oz/ton Au and 2.41% Cu. Sulphide mineralization (pyrite, chalcopyrite) is found in northwest/southeast trending shear zones which splay off the northeast-trending lineament. Minor disseminated pyrite mineralization has been observed within the mafic tuffs. The Main Showing has a 150 m strike length and averages approximately 0.5 m wide. The best results from channel sampling assayed 0.458 oz/t (15.7 g/t Au) over 30 cm and 0.132 oz/t (4.5 g/t Au) over 95 cm (Assessment report 52C16SE0008). While this showing is labelled as the Calm Lake showing, the original Calm Lake shaft is now believed to be located at the Calm Lake showing (MDI52C16SE00004).
