- The showing, or drill holes WV4-1 to -3, are located northwest of the north shore of Robinson Creek approximately 0.37 mile (0.60 km) northwest of the Robinson Creek Gold Showing or 0.9 mile (1.5 km) east of the Graham Gold Showing.
A large portion of the showing area is covered by massive Amisk Group basalts. In the northeast corner of the property, the basalts are bounded by the Reynard Lake granodiorite. In the southwest half of grid 4-83, the basalts are bounded by Missi Group conglomerates and greywackes which have been intruded by a massive to well foliated feldspar porphyry.
The rocks in the showing area have undergone several generations of shearing and at least two generations of isoclinal folding.
In 1984, SMDC completed 4 drill holes to test this package of rocks in areas of anomalous IP and geochemical readings. Three of the drill holes intersected the mineralization that constitutes this showing.
The drill holes intersected basalt, contorted chlorite schist (altered basalt) and feldspar porphyry hosting epidotized and chloritized auriferous quartz, quartz-ankerite, ankerite-calcite and quartz-ankerite-calcite veins. The veins are mineralized by trace to 1% pyrite, trace to 1% magnetite, trace chalcopyrite, limonite and hematite and, rarely, visible gold. The best assay values received in each hole are as follows:

- Exploration History
- 4/19/1991 The early prospecting of the general showing area located the Graham gold deposits (SMDI) and the Robinson Creek Showings (SMDI.0298).
Between 1914 and 1932, the Graham deposit was developed and reportedly mined for a short period using a 10 ton per day mill installed on the property, but no production figures are recorded. Within this time period, the Robinson Creek gold showings were discovered. A large volume of exploration work was performed on the Robinson showings, over the years, but no production of ore resulted.
In 1954, Byers and Dahlstrom geologically mapped the general showing area at a scale of 1" to 1 mile for the Saskatchewan Department of Mineral Resources.
By 1983, SMDC had surrounded the ROD claims by CBS 8867. In this year, SMDC completed detailed geologic mapping and soil sampling of grid 4-83 located on CBS 8867 to the east of the showing (AF 63L16-0090). Two soil samples returned 430 and 480 ppb Au. In 1984, SMDC completed four drill holes on this grid (AF 63L16-0099). Drill hole WV4-2 discovered the mineralization described as SMDI 2227. Between 1983 and 1985, SMDC completed ground VLF-EM, magnetic, IP and soil sample surveys over grid 4-83 (AF 63L16-0105). No significant gold values were returned. In the winter of 1987, Cameco completed drill hole BT7-01 close to the drill holes that constitute this showing on grid 5-87 (AF 63L16-0120). A number of quartz-carbonate filled, pyritic shears were encountered - but gold values returned were low.
