Capsule Geology

The Silvertip Hill occurrence is located 1.2 kilometres south of the Midway deposit (104O 038), on a branch of the Tootsee River called Silvertip Creek.

Galena, sphalerite, and tetrahedrite replacement mineralization occur in highly oxidized zones in the Middle-Upper Devonian McDame Group limestone just west of a fault zone separating McDame carbonates from a down-dropped block of Upper Devonian to Lower Mississippian Earn Group clastic sediments. A sulphide zone 12 metres in length was exposed underground, but surface mineralization is generally oxidized, with residual galena and minor sphalerite. Stannite has been identified in the sulphide assemblage, and a magmatic-hydrothermal source is suspected. The average grade for 21 channel samples across 3 to 10 metre widths is 195.4 grams per tonne silver, 6.2 per cent lead and 2.9 per cent zinc (Minister of Mines Annual Report 1968, page 26).

In 1955, an argentiferous galena outcropping on Silvertip Hill was discovered by A. Zborovsky, V. Alfody, S. Mezaros and S. Papp working under a government grub staking program. Refer to Midway (Silvertip) (104O 038) for a detailed work history of the area.
