The NL showing outcrops along Highway 101, 300 metres northeast of the west end of North Lake on Sechelt Peninsula.
A roadcut along the highway reveals a vein (NL zone) hosted in granodiorite within the Jurassic to Cretaceous Coast Plutonic Complex. The vein strikes 045 to 050 degrees for an exposed length of 30 metres and dips 65 degrees north. The vein varies up to 0.27 metre in width. Diamond drilling indicates the vein continues downdip for at least 55 metres. Six subsidiary tension veins ranging from 3 to 15 centimetres in width are developed in the granodiorite along the northwest side of the main vein over a distance of 20 metres. The tension veins strike 080 to 100 degrees for up to 8 metres and dip 65 degrees north.
The veins are comprised of marcasite in a gangue of quartz. A chip sample of the main vein taken across a width of 0.46 metre assayed 23.6 grams per tonne gold and 40.1 grams per tonne silver, while a sample of a tension vein taken over a length of 1.8 metres assayed 50.39 grams per tonne gold and 54.5 grams per tonne silver (Assessment Report 11129, page 24; Samples R-NL-1, R-NL-X-5). An angled diamond-drillhole (DDH-10) cored a 0.91 metre section grading 37.0 grams per tonne gold and 27.5 grams per tonne silver (Assessment Report 14736, page 20).
In 1995, a sample was taken from a shallow trench exposing the North Lake FW vein near Highway 101 where the vein splits into hangingwall (HW) and footwall (FW) portions separated by 61 centimetres of barren granodiorite. Grab sample 5WJR-1 yielded 1.41 grams per tonne gold and 15.77 grams per tonne silver (Assessment Report 24069). A grab sample (5WJR-2) of the HW vein from the same general location yielded 2.81 grams per tonne gold and 4.46 grams per tonne silver (Assessment Report 24069).
A silicified shear zone (TY zone) striking 110 degrees and dipping steeply north, outcrops 240 metres northeast of the NL zone. Quartz veins ranging from 20 to 50 centimetres in width are developed in the hangingwall of the shear. The veins are mineralized with pyrite and minor chalcopyrite. Grab samples have yielded assays of up to 6.99 grams per tonne gold and 175.5 grams per tonne silver (Assessment Report 14736, page 21).
