The Electrum occurrence is located on the north western side of the Malksope River, approximately 3.5 kilometres north east of the River mouth.

The region of the Electrum occurrence is underlain by Lower Jurassic Bonanza Group intermediate to felsic flows and pyroclastics. Minor calcareous sediments of the Upper Triassic Vancouver Group, Parson Bay Formation are in fault contact with the volcanic rocks. A diorite stock of the Jurassic Island Intrusions occurs at the head of Kashutl Inlet, 7 kilometres northeast.

Two mineralized veins have been recognized, the Electrum vein, occurring within interbedded limestone, calcareous siltstone and basalt, and the Anomaly Creek vein, located 80 metres west in siliceous limestone and basalt. Both veins occur at the basalt- sediment contact and are on strike with each other, suggesting continuity.

The quartz-carbonate Anomaly Creek vein returned values to 13.75 grams per tonne gold and 624.08 grams per tonne silver over 1.1 metres (Assessment Report 15521, Figure 16). In 1987, the best drill intersection yielded 5.9 grams per tonne gold and 342.86 grams per tonne silver over 0.91 metres (Hole 87-25; Assessment Report 17763)

The Electrum vein comprised of banded quartz carbonate is 1.5 to 3.0 metres wide and has been exposed over 75 metres. It strikes west and dips 45 degrees south. Locally, it contains 2 to 25 millimetres thick seams of chalcopyrite-sphalerite-galena-pyrite and electrum. On the east side, the vein is terminated by a 125 degree striking fault that dips west at 60 degrees. The Electrum vein is included in what is being referred to as the "B Zone", which contains two quartz veins about 4 metres wide. The Electrum vein and B Zone are likely a westward continuation of the "Main vein" of Assessment Report 11664 (Figure 5).

In 1982, drill hole SDH 82-5 intersected the main vein yielding 1.581 grams per tonne gold and 11.7 grams per tonne silver over 8 metres, with up to 4.3 grams per tonne gold and 30.1 grams per tonne silver over 1 metre (Assessment Report 11664). 1986, six panel samples averaged 9.26 grams per tonne gold and 431.37 grams per tonne silver (Assessment Report 15521, page 9). In 1987, work on the B Zone included 14 percussion drill holes. Assay values ranged from 3.4 to 127.9 grams per tonne gold; the latter value, with 2571.8 grams per tonne silver, over a 4 metre width (Vancouver Stockwatch, August 26, 1987). Drilling on another large vein in the same area averaged 3.4 grams per tonne gold or higher over 1 to 2 metre widths (average of 6 out of 18 holes). The highest value was 13.4 grams per tonne gold and 102.9 grams per tonne silver over 2 metres (Vancouver Stock- watch, August 26, 1987). Additional 1987 drill results include values to 30.18 grams per tonne gold over 2.0 metres and 960 grams per tonne silver over 1.8 metres (George Cross Newsletter #44, November 4, 1987).

In 1982, BP Minerals completed a program of geological mapping, rock sampling and 6 diamond drill holes, totalling 814.4 metres. During 1986 through 1989, Taywin Resources completed programs of geological mapping, geochemical sampling, trenching and 8 diamond drill holes, totalling 304.9 metres, on the area as the Sin 1-7 claims. In 1998, the area was prospected by J.D. Graham.
