The Elmer occurrence is located 150 metres south of Ursus Creek, approximately 35 kilometres northeast of Tofino, B.C.

The area is underlain by middle to late Triassic Karmutsen basalt. These basalts are overlain by massive to thickly bedded calcareous mudstones of the Quatsino Formation. These volcanic and stratified rocks have been invaded by a middle to late Jurassic biotite-hornblende granodiorite and quartz diorite. The area has been subjected to major faulting with a dominant northwest-southeast trend.

The Elmer zone consists of two parallel quartz veins located 25 metres apart in an extensive shear zone. The quartz veins vary from 0.2 to 1.0 metre wide and have been detected over a 300 metre strike length. Sulphide mineralization in the veins includes up to 20 per cent pyrite, 10 per cent galena and 5 per cent sphalerite. The veins are hosted by chlorite and carbonate altered quartz diorites.

Sampling of the veins assayed up to 38.4 grams per tonne gold and chip sampling of the host quartz diorites assayed up to 3.4 grams per tonne gold (Assessment Report 26412).

The area was originally explored in 1939 with the discovery of float containing coarse gold near the junction of Ursus and Thunderbird creeks. In 1979, the property was acquired by S. Craig and later optioned to Eldorado Minerals and Petroleum as the Ureka and Opus claims. In 1984, Eldorado completed a program of trenching and geochemical sampling that identified the Camp Zone (MINFILE 092F 067). From 1986 to 1987, Pacific Sentinel Gold completed programs of geochemical surveying, geological mapping and magnetometer and VLF surveys. This work identified three new zones, including the Junction (MINFILE 092F 450), and Mid-Pad (MINFILE 092F 449) occurrences. From 1988 to 1989, Pezgold Resource optioned the property and completed a program of diamond drilling on the Junction zone, and prospecting which led to the discovery of the Elmer zone to the east. In 1990 Pacific Sentinel Gold completed a program of geological mapping, rock sampling and trenching. In 1995, the area was prospected as the Thunderbird claims by S. Salmon. In 1999, the area was claimed as a part of the Thunder claims and a program of geological mapping, geochemical sampling and geophysical surveys were completed on the Elmer zone.
