The Silverado occurrence is located on the south western side of Silverado Creek, approximately 1.2 kilometres south east of the creek mouth.

The area is underlain by limestone and volcanic rocks of the Paleozoic-Mesozoic West Coast Complex. Granodiorite of the Muchalat Batholith of the Jurassic Island Plutonic Suite lies immediately east of the occurrence.

The Silverado adit and workings explored a zone of discontinuous lenses of sphalerite that have partly replaced a 3-metre wide bed of limestone along a greenstone contact. The contact strikes 330 to 340 degrees and dips 75 degrees west. The greenstone is a tuff or lava, re-crystallized to hornblende hornfels. It is overlain by a second limestone unit that is 24.4 metres thick and has been intruded by a 5-metre wide feldspar porphyry dyke. The dyke trends north and dips 75 degrees west.

The zone of sphalerite lenses is traceable on the surface for 113 metres. As seen on the surface and in the drift, the lenses range in width from a few centimetres to 2.0 metres and in length from 8.0 to 30.0 metres. Several diagonal faults cut the lenses. A fault at the intersection of the crosscut and the drift displaces the mineralized lens 9.0 metres to the left. The direction and displacement along the fault are unknown.

The mineralized lenses consist of sphalerite with small amounts of chalcopyrite, pyrrhotite and magnetite in a gangue comprised mainly of quartz, calcite and light-green diopside. Much of the mineralization is rhythmically banded with layers of sphalerite and gangue 0.2 centimetre to 2.5 centimetres thick.

A zone of lime-silicate minerals up to 1.2 metre thick occurs on either side of the ore lenses in the south drift. In the north drift skarn extends along the west side of the ore and continues north to the face beyond the extent of the ore. The minerals in this zone include quartz, calcite, diopside, tan garnet, cream-coloured zoisite and, in small amounts, scattered grains of sphalerite. A sample submitted to the Mines Branch, Ottawa, assayed 0.18 gram per tonne gold, 11.0 grams per tonne silver, trace lead, 10.0 per cent zinc and 0.04 per cent copper (Energy, Mines and Resources Canada MP Corpfile).

A "Lower Showing" is reported to be a 1.5-metre wide vein in altered limestone at a hornblende-feldspar porphyry contact. The exposed mineralization assayed from 15 to 20 per cent zinc (Property File-Geological Plan 1:240 by J.S.S).

Production reported from Baltic (092E 026) included an undisclosed amount of ore from the Silverado occurrence (Minister of Mines Annual Report 1949, page 219). Between 1934 and 1938, 130 tonnes of ore from the Baltic and Silverado adits (Danzig property) reportedly produced 5567 grams of gold, 10,294 grams of silver and 87 kilograms of copper. "Some 27,216 tonnes of medium-grade zinc" remained in 1951 (Energy, Mines and Resources MR 223, 1989).

In 1981, Dynamic Oil Ltd. completed a program of geological mapping, rock, soil and silt sampling and airborne geophysical surveys on the area as Wyn claims.
