Gold mineralization at the Ketza River Mine occurs in massive manto replacement deposits along preferred horizons within Lower Cambrian limestone. Primary economic deposits occur on the south flank of the Ketza Uplift, postulated to be related to a Cretaceous buried intrusion. The Ketza Uplift appears to be associated with a major gold-bearing alteration system, with potential for large disseminated and stringer-stockwork type gold deposits in Lower Cambrian clastic rocks.
On the Ketza River property, the structural setting and mineralogy of the Shamrock zone is suggestive of the Carlin-type deposits of Nevada. This zone has undergone the same strong deformation as the manto deposits but further structural mapping is necessary to define the gold distribution. Future plans include re-mapping the property and re-interpretation of the structure.
