Feb 06, 2007 (Mark Puumala) - Jowett (1990) indicates that the area southwest of Kapkichi Lake consists of a narrow (northeast-trending) band of supracrustal rocks of the Pickle Lake Greenstone Belt that are bounded to the northwest by the Dobie Lake Batholith and to the southeast by the Pickle Lake Stock. The immediate area of the occurrences was mapped by Ackert (1989), who noted limited outcrop exposure in the area. Lithologies identified by Ackert (1989) included metasediments and granodiorite. The metasedimentary rock stratigraphy was noted to as 280/70-85. A geophysical interpretation map (AFRI# 52O08NW0008) that was subsequently prepared by Bond Gold indicates that the occurrences are located adjacent to the contact between granodiorite and a thin unit of mafic metavolcanics. Jowett (1990) indicates that the geological structures of the area include shearing and folding that was likely attributable to the effects of the emplacement of felsic intrusive rocks on both sides of the narrow supracrustal sequence. Jowett (1990) has also interpreted the existence of north-northeast striking faults based on the interpretation of airborne magnetic data.

Feb 06, 2007 (Mark Puumala) - The diamond drill hole log prepared by Bond Gold for ddh KP89-09 (AFRI# 52O08NW0008) indicates that this occurrence is hosted within an approximately 12.5 m wide drill section logged as sulphidized biotite quartz schist. This material occurs within a granodiorite intrusion and contains quartz veining and felsic dikes. Sulphides occur as thin laminae along foliation planes, as fracture and vein fillings (1 to 10 mm wide), as breccia fillings and as massive pods. The sulphide minerals were identified as pyrrhotite (3-5%), pyrite (2-3%) and chalcopyrite (1-2%). The most notable reported assay was 14,100 ppm Cu over 0.7 m.
