The Cliff occurrence is located at about 1067 metres elevation on the Cliff Reverted Crown grant (Lot 2606), east of Emily Creek. Silverton, British Columbia lies 2.75 kilometres to the west.
The Cliff claim was first Crown granted in 1898. Little geological information is available for the Cliff occurrence. Some general information with reference to the Cliff occurrence is given in Geological Survey of Canada Memoir 308, pages 184-185. The occurrence is described as a zinc-lead-silver fissure-filled lode deposit with silver production exceeding lead. These deposits may contain some disseminated sulphides in the adjacent wallrock. The country rocks are argillite, quartzite and limestone of the Triassic Slocan Group. Gangue minerals include quartz, calcite and siderite. Wallrock fragments are common in veins. Ore minerals are mainly sphalerite, galena and pyrite. A 60-metre adit follows part of the vein which strikes east-west and dips 50 degrees north.
Reference to production on the Cliff occurrence dates back to 1932. Production records indicate 21 tonnes was mined in 1932, 1935 and 1936. This yielded 32,098 grams silver, 2278 kilograms lead and 3542 kilograms zinc.
