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 KP89-05 (AFRI# 52O08NW0008) indicates that this occurrence is hosted within a body of massive sulphides (an approximately 6 m drill section) that occurs within felsic intrusive rocks logged as epidotized granite and quartz feldspar pegmatite. The massive sulphides are approximately 1 m from the contact between the granitic intrusive rocks and material logged as a sulphidized amphibolitic flow. The massive sulphide unit is indicated to consist of approximately 80% pyrrhotite, 15% pyrite and 2% chalcopyrite. The massive sulphides are also indicated to contain several quartz/feldspar veins and inclusions of sheared amphibolite. The most notable reported assays include 13,360 ppm Cu over 0.6 m and 3090 ppm Ni over 0.8 m from separate sections of ddh KP89-05. Approximately 125 m to the west, an assay of 5790 ppm Cu was reported from a 0.6 m section of massive sulphides hosted within amphibolite and located within 1 m of a contact with a granitic intrusion.
