Capsule Geology

The Munro occurrence is hosted by siliceous and tuffaceous argillites with intercalated siltstone of the Lower Jurassic Unuk River Formation of the Hazelton Group. This sedimentary unit forms a roof pendant in medium-grained biotite-hornblende granodiorite of the Eocene Boundary Stock of the Hyder Pluton. Metamorphic grade is upper greenschist with local amphibolite facies. Occasionally, hornfelsic and calc-silicate rocks are formed.

A quartz vein, striking 140 degrees and dipping northeast, occurs within the sediments. The vein is about 130 metres long and between 7 and 70 centimetres wide. Mineralization consists of galena, sphalerite, tetrahedrite and minor pyrite in pods and irregular stringers.

During 2004 through 2019, the area has been explored as apart of the Silver Coin property and a complete property exploration history can be at the nearby Silver Coin (MINFILE 104B 150) occurrence.
