The Cy 4 and Mount Weir occurrences are located on Mount Weir, about 41 kilometres east of Atlin, British Columbia.
The following quote is from B.C. Government site โ€œMinfileโ€- Minfile No. 104N 087, current to 2013:
โ€œMount Weir lies within the Surprise Lake batholith (Surprise Lake Plutonic Suite), a Late Cretaceous lobe of the Coast Plutonic Complex. The batholith consists of several phases of alaskite, quartz monzonite and granite.
In Zone A, fractures filled with smoky quartz veins and hosting galena, sphalerite, magnetite and hematite occur in coarse-grained alaskite. A grab sample from a 20 centimetre wide, 40 centimetre long quartz vein assayed 0.15 per cent uranium, 0.11 per cent lead and 4.0 per cent zinc (Assessment Report 6898). In 1977, the original discovery zone, Anomaly or Zone A, was found on the summit of Mount Weir, as a result of ground follow up of helicopter-borne radiometrics.
In Zone C, about 300 metres to the south, a yellow-orange coloured zone of supergene alteration, exposed over an area 10 by 40 metres, contains kasolite, wulfenite and vandendriesscheite. The mineralization likely leached from the highly fractured alaskite.โ€
