The JJ occurrence is located on a ridge separating the north and south forks of Ed James Creek, approximately 2.4 kilometres west of the south end of Ed James Lake.
The area is underlain by Permian to Upper Triassic Anarchist Group greenstones, limestone and argillites. These rocks have been intruded by Cretaceous granites of the Nelson and Valhalla Plutonic Suites. Both the Anarchist Group and Nelson and Valhalla intrusive rocks are overlain by the sedimentary Kettle River Formation, which is in turn overlain by Tertiary Phoenix Group volcanics.
Locally, metasedimentary rocks of the Anarchist Group host two mineralized shear zones, located 200 metres apart, on the north and south sides of a gossanous zone. The shear zones strike 050 degrees and dip 60 to 90 degrees to the southeast.
In 1999, a 0.15 metre wide chip sample across the first (southern) shear zone assayed 295 grams per tonne silver, 0.865 gram per tonne gold, 0.371 per cent lead and 0.497 per cent zinc (Assessment Report 26326).
In 1984, Westbridge Resources completed a program of soil sampling and ground geophysical surveys on the area as the Rock 4 claim. This work identified three anomalous zones. In 1994, Module Resources prospected the area as the Chris 1-8 claims. In 1999, the area was prospected as the JJ (J&J) claims.
