The Wasi-Beveley occurrence is located on the north shore of the Osilinka River, near where Wasi Creek enters from the south, 28 kilometres northwest of the community of Germansen Landing or approximately 200 kilometres north of Fort St. James.

The region is underlain by the Neoproterozoic Ingenika Group and Paleozoic rocks of the Big Creek, Otter Lakes (equivalent to McDame Group) Atan, Razorback (equivalent to the Road River and Kechika groups) and Echo Lake (equivalent to the Sandpile Group) groups.

The Beveley area is underlain by carbonate and sedimentary sequences of the Lower Cambrian Mount Kison Formation (Atan Group), the Ordovician to Lower Devonian Echo Lake Group and the Cambrian to Ordovician Razorback Group. The stratigraphy has been subdivided into four units on the property and consists of: 1) white to grey dolomite and dolomite breccia; 2) grey to black limestone; 3) brown ferrodolomite; and 4) minor brown sericite schist and phyllite. Of these units, the dolomite and dolomite breccia are the most important economically because almost all significant lead-zinc-silver mineralization is associated with it.

All rock units are highly fractured, faulted and sheared. Faults have a diversity of strikes and are numerous. Where fractures are abundant and closely spaced, they produce a bedded appearance that is difficult to distinguish from true bedding. The main structural feature appears to be a north trending major anticline that plunges gently to the north. The west limb of the anticline appears to be overturned while the east limb dips shallowly to the east. Within this framework, the carbonate rocks have developed a number of minor folds, flexures and warps which seem to act as "traps", localizing mineralization on the limbs, crests and troughs of some of the minor folds.

The mineralized zones are contained within a somewhat rectangular or wedge-shaped limestone fault block that is bounded on the north by the "Camp" fault and to the west by the "Lost Creek" fault system. Numerous other faults occur within this block; the largest and probably one of the most important is the northwest striking "Beveley" fault. This fault separates limestone, dolomitized limestone and dolomite breccia to the east, from silicified dolomite and silicified dolomite breccia to the west. Most of the mineralized zones are on the east side of this fault.

Several mineralized zones are associated with a dolomite breccia within a surface area of 1500 by 500 metres and are named as follows: Bullseye, Bullseye West, O, G, E, C and Y. The dolomite breccia unit is 40 to 50 metres thick, is overlain by a limy argillite 20 to 40 metres thick and underlain by a phyllite unit 200 metres thick.

Mineralization consists of galena, sphalerite, acanthite, tetrahedrite and barite with calcite stringers and occasional pyrite, all accompanied by dolomitization and some silicification. Better grade material appears to be associated with areas of intense dolomitization. Barite occurs in massive veins and patches and is also found in the best mineralized sections. Galena and barite veins can be seen crosscutting dolomitized sections that contain vugs and open-space textures. Argentiferous galena is the most important and conspicuous sulphide and occurs as veinlets and ramifying, discontinuous and thin fracture fillings in barite masses in brecciated dolomite breccia. It also occurs as disseminated grains and small patches scattered throughout the dolomite. Sphalerite occurs as fine disseminations and only occasionally as massive patches or stringers.

The mineralized zones within this dolomite section are irregular, discontinuous, lensoidal and often sinuous and generally associated with areas of intense fracturing or restricted narrow zones of shearing. This erratic distribution results in difficulty correlating mineralized sections between drillholes and, in turn, establishing reliable grade and tonnage figures.

In 1946, the original showings were discovered by A. Leggatt of Cominco at an elevation of 1410 metres. Exploration on the property from 1949 to 1951 consisted of 2400 metres of trenching and 12 short diamond-drill holes. Cominco stopped exploration in 1951 and dropped the property in 1962.

The property was optioned to Donna Mines in 1967 by E.D. Vinnedge & Associates before being dropped again in 1969. During this time, an access road from Tenakihi Creek to a base camp at 1500 metres elevation was completed, along with geological and geophysical surveys of the area. This work was followed up by 5700 metres of bulldozer and backhoe trenching, a 300-metre adit and three diamond-drill holes totalling 150 metres. As a result of this work, nine zones of mineralization were outlined with exposed discontinuous mineralization over a length of about 1000 metres.

By 1978, Suzie Mining Explorations had acquired the property and performed gravity, induced polarization and electromagnetic surveys. This was followed by 51 diamond-drill holes totalling 3150 metres. The drilling during 1978 and 1979 by Suzie Mining Explorations Limited encountered an intersection of approximately 10 metres of 4.47 per cent lead-zinc and 100.1 grams per tonne silver near the surface. In the C zone, hole 78-33 intersected 10.5 metres of 3.62 per cent lead-zinc and 17.1 grams per tonne silver (Property File Cyprus Anvil - Suzie Mining Exploration Ltd., 1979).

Drill indicated reserves of the Bullseye zone are 99,781 tonnes grading 1.42 per cent lead, 2.24 per cent zinc and 36.3 grams per tonne silver (Property File - Statement of Material Facts, October 25, 1978, Suzie Mining Explorations Ltd., K.C. Fahrni, September 11, 1978). Inferred reserves are 2,721,300 tonnes grading 36.3 grams per tonne silver and 3.66 per cent lead-zinc in three zones (Northern Miner - December 7, 1978).
