The Kit occurrence lies 2.5 kilometres northwest of the Granduc ore deposit (104B 021), on the east side of the North Leduc Glacier. The occurrence, which is located within the 120 metre wide, north- trending South Unuk cataclasite zone (Lower Jurassic), lies within metavolcanics of the Lower Jurassic Unuk River Formation (Hazelton Group). All rocks are cut by Tertiary quartz diorite plutons and dykes.
Mineralization, consisting of disseminated and massive podiform magnetite, occurs within metamorphosed actinolitic dark green ande- site. A ground magnetometer survey outlines a strong north-trending, 700 metre long magnetic anomaly over the occurrence.
