The TJ occurrence is located approximately 6 kilometres east-northeast of the confluence of Red Creek and the Sustut River (Showing #5, Assessment Report 4892).

The local and regional geology is similar to that of the Tie occurrence (refer to 094D 089). The area is underlain by Upper Triassic Dewar Formation (Takla Group) tuffs, sandstones, argillites, limestones and breccias. Chalcopyrite, chrysocolla and pyrite are disseminated in quartz-carbonate filled pyroclastic breccias. The mineralization outcrops over an area of about 6 by 9 metres. A rock sample from this zone assayed 1.4 per cent copper (Assessment Report 4892).

Between August 18th and August 26, 1973, a crew of four geologists and three assistants from Vestor Explorations Ltd. conducted a program of geological mapping and stream sediment sampling on the Tie and Jan claim groups. Some limited prospecting was carried out in the course of traverse geological mapping and 9 minor copper occurrences were discovered. About 200 stream sediment samples and a limited number of soil samples were obtained. Only 5 rock samples were collected.

In 1974, a combined magnetic and electromagnetic survey 640 kilometres in total length was completed on behalf of Rio Tinto (Assessment Report 4921). Several high conductivity anomalies were recommended for follow-up. The Rio Tinto survey encompassed the following MINFILE showing areas: TJ (094D 050), Park 2 (094D 052), East Ridge (094D 053), Pond (094D 054), Red Copper (094D 055), Eight (094D 074), Pluto (094D 075), Tie (094D 089), A462 (094D 102).
