Ian SE occurrence is located at an elevation of approximately 1480 metres on a south-trending ridge of Mount Dahl.
The area is underlain by fine to coarse clastic sedimentary rocks of the Jurassic Nechako and Ashman formations, volcanic rocks of the Jurassic Naglico and Nechako formations (all Hazelton Group) and undivided volcanic rocks of the Jurassic Fawnie volcanics (Bowser Lake Group). Late Cretaceous to Miocene stocks and plugs intrude the strata.
Locally, at the Ian SW occurrence, a quartz-sericite–altered andesite with local quartz veinlet stockworks and disseminated pyrite and arsenopyrite hosts anomalous gold values.
Another zone of similar mineralization, referred to as the Ian zone, is located approximately 800 metres to the northwest. This zone is exposed for greater than 175 metres along an east-west–trending ridge.
Work History
The Ian occurrence was originally identified in 1994 by BCGS regional mapping.
In 1995 and 1996, Kennecott Canada Exploration Inc. completed a program of geological mapping, geochemical (rock and soil) sampling and a 250.0 line-kilometre airborne magnetic and electromagnetic survey on the Java 1-8 claims. A grab sample (VR32644) from the Ian SW zone assayed 0.185 gram per tonne gold, whereas samples (VR-32066 and -32067) from the Ian zone to the northeast yielded up to 0.095 gram per tonne gold (Assessment Report 24829).
