The Seabee occurrence is situated along the southwestern shore of Kinskuch Lake, 20 kilometres north-northeast of Alice Arm. Various gossan zones were explored in the area in 1956.

The Kinskuch Lake area is underlain by volcanics and sediments of the Upper Triassic Stuhini Group and the Lower Jurassic Hazelton Group. These occur along the eastern limb of the north to northwest trending Mount McGuire anticline and have been regionally metamorphosed to greenschist facies.

The Seabee occurrence consists of widespread gossanous zones, more localized pyritic shear zones and veinlets containing variable quartz, calcite and barite hosted in Hazelton Group volcanics. The gossanous zones occur sporadically around the southwestern shore of Kinskuch Lake and are commonly hosted in light grey sodic rhyolite. In outcrop, these zones tend to be elongate and trend north to northeast. Individual zones extend up to 140 metres and vary in width up to 43 metres. The pyritic shear zones occur more commonly in the dark green epidote-altered andesite. Lenticular veins of variable quartz, calcite and barite, up to 13 millimetres in width, are found in both volcanic types.

Mineralization in the gossan zones comprise widespread finely disseminated pyrite and minor chalcopyrite. The shear zones are more intensely pyritized and contain minor fine disseminated chalcopyrite. The quartz-calcite-barite veinlets often contain pods of pyrite with minor chalcopyrite and traces of galena. Chip and channel sampling revealed low copper values and trace gold. The best assay came from a 9.1 metre chip sample across a series of quartz veinlets containing visible pyrite and chalcopyrite which assayed 0.51 gram per tonne gold and 0.70 per cent copper (Assessment Report 124, page 8).

In 2008, as part of a large exploration program conducted on behalf of owners Rand Edgar Smyth Syndicate, Durango Capital Corp., Dolly Varden Resources Ltd., Teck Cominco Limited and C.G. Brookes, two drillholes (08-BB-13 and 14) totalling 475.5 metres tested a chargeability high area resultant from a 2008 induced polarization survey. Both holes intersected significant intervals of disseminated sulphides. Drillhole 08-BB-13 collared directly into a chargeability high in which it remained. This chargeability high consisted of altered and mineralized diorite porphyry very similar to that seen elsewhere at Big Bulk (103P 016) and at Midnight Blue. Alteration intensity was typically high comprising chlorite, epidote, sericite and quartz with lesser magnetite and hematite. Pyrite, present in veins/stringers and as disseminations, composed 1-5 per cent of the rock while trace level chalcopyrite was rarely present. In drillhole 08-BB-13, a 9.15 metre interval (from 132.16 to 141.31 metres) assayed 0.08 gram per tonne gold, 0.16 per cent copper and 0.59 gram per tonne silver; a 7.58 metre interval in the same hole (from 194.62 to 202.20 metres) assayed 0.35 gram per tonne gold, 0.08 per cent copper and 2.11 grams per tonne silver (Assessment Report 30581).
