The C.O.D. North occurrence is located on south-facing slopes near the south western end of Jewel Lake.

The area is underlain by a complex of metamorphic rocks, mostly of sedimentary and volcanic origin correlative with the Carboniferous or older Knob Hill Group, and a large granodiorite intrusion correlative to the Juro-Cretaceous Nelson Plutonic Rocks. Small dikes and sill-like bodies, feeders to nearby Tertiary lavas, pervade these units. Four north- striking and one northwest striking quartz fissure-vein structures are known in the Jewel Lake camp, all of which have received some development.

Locally, a 0.1 metre wide “Dentonia-type” quartz vein in granodiorite is reported and has been explored by a shaft. A grab sample of the vein assayed 7.0 grams per tonne gold and 69.6 grams per tonne silver (Property File - W.W. Cummings [1986-07-17]: Report on the Tel 2 Mineral Claim). In 1983, a sample (61930) of dump material assayed 7.8 grams per tonne gold and 64.6 grams per tonne silver (Assessment Report 11925).

During the early 1900’s, the area was staked as the C.O.D. claims and a shaft was sunk on the vein. During 1983 through 1988, Glendale and Blackmist resources explored the area as the Tel 1-2 claims.
