Jun 01, 2018 (Therese Pettigrew) - The Angela Lake occurrence lies within the strain aureole of the Keigat Lake granitoid complex. Structures trend northwest, parallel to the granitoid contact in the vicinity of the occurrence (Parker and Atkinson, 1992).

Jun 01, 2018 (Therese Pettigrew) - The property is underlain by mafic metavolcanic flows and pillow breccias of the Cycle II metavolcanic sequence. Diamond drilling on the property, by Dome Exploration (Canada) Ltd., intersected mafic metavolcanic rocks, siliceous metasediments, ironstone, chert, argillite and intermediate tuffaceous rocks. Lamprophyre dikes commonly intrude the metasedimentary units. Alteration includes silicification and carbonatization of the mafic flows as well as chloritization, biotitization and sericitization. Minor tourmaline is reported in diamond drill logs (Parker and Atkinson, 1992). Pyrrhotite, pyrite, chalcopyrite, and sphalerite occurs in the quartz and carbonate veinlets and as disseminations (SMDR 00501).

Nov 22, 2014 (A Wilson) - The occurrence displays widespread pyrrhotite and pyrite with minor chalcopyrite and sphalerite as disseminations. Assays returned generally less than 0.3% Cu, 0.3% Zn and erratic low silver values. DDH 10 returned an assay of 0.42% Cu, 0.38% Zn and 0.13 oz/t Ag between 174 and 181 ft. A drill hole completed in 1985 returned an assay of 0.13 oz/t Au
Jun 01, 2018 (Therese Pettigrew) - Gold-bearing float has been found on the property. Stringers of massive pyrrhotite and pyrite with minor chalcopyrite and sphalerite mineralization have been intersected in drill core (Parker and Atkinson, 1992).
