Dec 07, 2005 (K R Kettles) - The claims are underlain by rocks of the Dome granite-granodiorite stock which are cut by two generations of mafic dikes. The felsic rocks contain inclusions of recrystallized mafic volcanics. The pre-ore mafic dikes are highly altered. The older generation of dikes occur along N 35 degs/65 degs NE fractures whereas the younger generation of dikes occur along fractures and shear zones striking N40 degs E and dipping 80 degs to the SE. The mineralized zone which provided most of the ore mined occurs in the vicinity of the junction of 2 sets of shears. Repeated movement in the N40 deg E shear produced a dislocation of 50 feet in the N35 deg W shear. The fractured rocks in the vicinity of this dislocation acted as a locus for the formation of a pipelike orebody. Most of the gold occurs in quartz lenses and stringers in fractured granite, with minor amounts occurring in sheared and altered mafic dikes. GEOPHYSICS: The Mine is located in an area in which the magnetic contours are very irregular as compared to the contours in the rest of the Dome Stock.

Dec 07, 2005 (K R Kettles) - The felsic intrusives range from pink granite to grey granodiorite and contain many small inclusions of recrystallized mafic volcanics. The pre-ore mafic dikes are grey to greyish white and are highly altered.

Dec 07, 2005 (K R Kettles) - The main orebody consists of auriferous quartz lenses and stringers in a pipe shaped volume of fractured granite. It is from 15 to 45 metres long and 1.5 to 9 m wide. It extends from the surface to a depth of 300 metres. The trend and plunge of the orebody varies from N75 degs E/70.5 degs NE to S78 degs E/68.5 degs E. Due to changes in the intensity of fracturing and quartz veining with depth there is a dimunition in grade and volume from the surface to the bottom of the mine. There is a similar but much smaller structure located approximately 35 metres SW of the main orebody and extending between the 127 and 210 m levels. Total production of the mine from 1936 to 1938 : 21,300 OZ AU, 3,603 OZ AG FROM 86,333 T MILLED (0.25 OPT AU,0.04 OPT AG), RESERVES 1940: ONLY 1 DDH BELOW 1000FT LEVEL INTERSECTED POSSIBLE ORE:0.212 OPT/5 FT. Apparently 2 shoots of ore were mined, the main shoot (vein 4?) and a southwest shoot.
Dec 07, 2005 (K R Kettles) - The granitic rocks adjacent to the quartz veins have been silicified and much of the feldspar has been altered to sericite and carbonate. Hornblende and biotite have been altered to chlorite. The mafic dikes have been altered to an assemblage of chlorite, carbonate, and quartz.
