Dec 07, 2005 (K R Kettles) - The property is underlain mainly by a thick sequence of mafic flows. A few thin units of iron formation are intercalated with the mafic flows. All rocks strike NW-SE and dip 35 to 50 degs to the southwest. Stratigraphic tops are to the southwest. Mineralization occurs in the unit of iron formation.

Dec 07, 2005 (K R Kettles) - Anomalous gold values were found in a unit of iron formation, over a strike lenght of up to 150 m but across narrow widths. The unit is believed to have a flat dip to the west. Gold mineralization occurs in a zone 150 m long, less than 1 metre wide, in iron formation. The auriferous zone was investigated by several diamond drill holes. Grades from the mineralized zone range from 0.03 opt Au to 0.12 opt Au/0.40 m. A section of core from hole #110 assayed 0.08 opt Au/0.43 m.
Aug 10, 2022 (Q Unknown) - Grade - several DDHs: range 0.03-0.12 opt Au over 0.4 m, DDH #110: 0.08 opt Au/0.43 m.
Dec 07, 2005 (K R Kettles) - The mafic metavolcanics have been carbonatized, silicified, and are biotitic.
