Aug 25, 2014 (A Wilson) - The quartz veins range in width from 10-25 feet. The veins are lenticular pipes that pinch and swell rapidly. The veins are predominantly composed of massive quartz. The best assays are returned from the most heavily pyritized portions of the vein. The veins are hosted by reddish intermediate intrusive rocks.

Aug 25, 2014 (A Wilson) - A chip sample collected by Jenner in 1940 returned 0.23 oz/t Au over 2 feet. Diamond drilling by Macassa in 1947 intersected 0.24 oz/t Au over 3 feet. Grab samples collected by Macassa Mines Ltd. in 1948 returned assays ranging from 0.01 oz/t Au to 0.09 oz/t Au. Grab samples collected by North Gold Fields in 1985 returned assays up to 0.4 g/t Au and 2.1 g/t Ag. The best assays obtained by North Gold Fields returned assays of 1.16 g/t Au and 5.1 g/t Ag over 4.3 m.

Geologist: A Wilson
Notes: At its southeastern end, the vein widens to over 30 feet in width. The vein is interpreted to be part of a silicified shear zone.
Date: Jun 21, 2001
Geologist: A Wilson
Notes: The Jenner appears to be associated with several separate structures. At the north end, there is a zone of N60W trending quartz veining that dips steeply south. About 20 m to the south, a second N60W structure is associated with a diabase dike and includes a sheared, chloritized and silicified zone. A third shear zone lies 9 m to the SW. This zone is about 2.5 m in width, sheared, chloritized and silicified. The vein displays evidence of folding. The folds rake to the west at 40 degrees.
