The Van Isle occurrence lies in the Zeballos gold camp. Production in 1940 came mostly from the "1800" level stope, where a narrow quartz-vein, striking 043 to 050 degrees and dipping 75 degrees west is hosted by steeply east dipping, northwest striking Lower Jurassic Bonanza Group andesite tuff and minor volcanic breccia. This vein, traced underground and on surface for 580 metres horizontally and 122 metres vertically, runs sub-parallel to a 032-degree striking vein that dips 80 degrees north. The second vein was encountered on the lower, 2000 level only, where it was traced for 49 metres.

Both veins range in width from up to 0.9 metre but average widths are less than 0.3 metre. The veins and the shear zones they follow are anastomosing over 1.2 metres. The shear zones are generally only a few centimetres wider than the veins. Vein quartz is generally massive but is sometimes ribboned with fine-grained pyrite, galena and sphalerite. Locally, massive pyrrhotite, arsenopyrite and calcite are present. In 1981, sampling of the 2000 level workings returned values that were strongly variable. Maximum values were 10.0 grams per tonne gold over 10 to 15 centimetres (Sample #2766) and 8.9 grams per tonne gold over 15 centimetres (Sample #2765) (Harrison, 1982). Bulletin 27, Figure 2 indicates 2 additional veins along Van Isle Creek, 460 metres upstream from the 2000 level portal, but no information is given.
