The area west of Mackenzie Cove is underlain by Upper Triassic Karmutsen basalts, metabasalts and minor limestone, which are intruded by diorite possibly related to the Jurassic San Christoval Plutonic Suite.
The Rod showing consists of a horizon of massive chalcopyrite and pyrite, 3 to 75 centimetres thick, hosted in epidote and clay altered basalts. Samples from the zone are reported to assay greater than 10 per cent copper (Assessment Report 22952, Figure 3).
This showing was sampled by Doromin Resources Ltd. in the early 1990s. Inco Exploration and Technical Services Inc. flew airborne electromagnetic and magnetometer surveys over the showing in 1992.
