In the region of the Unuk Jumbo showing, sediments and volcanics of the Upper Triassic Stuhini Group are are intruded by diorite and quartz diorite of the Upper Triassic Stikine Plutonic Suite.
A north-northeast, 3.7 metre wide zone of massive pyrrhotite, with 0.35 per cent copper, occurs within andesite porphyry (Newmont map). The andesites lie within a contact metamorphic zone which contains chloritic schists. Local areas of sheared volcanics with pyrrhotite occur to the southwest of this massive zone. Apparently, a rusty gossanous zone contains gold and barium values (Equity Preservation Corp. 1988).
The vicinity of the Unuk Jumbo was prospected and sampled in 1991 by Fest Resources. Assay values were not significant (Figure 5, Assessment Report 21666).
Work History
The Unuk Jumbo group is located on the west side of the Unuk River 1 mile south of La Brant Creek. The claims were staked by T.J. McQuillan and G.E. King in 1934.
In the 1960s Newmont Exploratin conducted a regional exploration program. The resulting geology map eventually ended up in the Property File of the Ministry of Energy, Mines and Petroleum Resources.
In 1989, Fest Resources collected 126 stream sediment samples and 12 rock samples for analysis on there Fis 1-5, Jade 2 & 3 and Jumbo 2. In, 1990 a airborne reconnaissance magnetic and VLF-EM survey was conducted on behalf of Fest Resources over the claim area. In 1991 a brief follow-up program of rock geochemical sampling and prospecting was carried out by Fest Resources. A total of 78 rock, 19 silt and 30 soil samples were collected for geochemical analysis.
In the late 2000s, the area was held by Max Resources who flew an airborne geophysical survey over parts of the area (Assessment Report 30289). No ground work in the Jade 2 (McQuillan) (104B 012) - Gracey Creek area was reported by Max Resources. Refer to Max (104B 013) for details of the activity of Max Resources at the time.
In 2006 and 2007, Hathor Exploration Ltd. completed a 7228.7 line-kilometre airborne geophysical survey on the area as the Sun claims of the Iskut project. In 2008, Max Minerals Ltd. examined the property.
