- The Studer B Showing is located approximately 150 m (492.1 ft) west of the west shore of a small un-named lake which is located 3.1 km (1.9 miles) west of the most westerly bay of Little Deer Lake. The showing, which occurs at grid coordinates 4+80E and 4+25N, is 4.0 km (2.48 miles) northwest of the Boundary South Showing or SMDI 2276. The Studer C Showing is located 950 m (0.59 mile) to the southeast of the Studer B Showing at grid coordinates 13+05E and 3+50N.
The general showing area is underlain by Glennie Domain meta-volcanics which consist of mafic to intermediate flows and pyroclastics and a series of volcaniclastic metasediments that range in composition from greywackes to turbidites. The Glennie rocks were metamorphosed to upper greenschist to lower amphibolite facies during the Hudsonian Orogeny. M.W. Thomas mapped the immediate showing area as being underlain by a northwest-trending belt of Unit Bn or grey to black, locally rusty, very fine- to fine-grained, foliated to slaty biotite wacke. The unit is made up of a series of quartz-feldspar-biotite±hornblende±muscovite±garnet schists. The metasediments have been locally intruded by small biotite granite plugs.
Structurally, the general showing area contains a two sets of regional lineaments that trend north to northwest and east to northeast. The northeasterly-trending lineaments reflect the later phase brittle style deformation while the northwesterly-trending lineaments reflect earlier plastic movement.
The Studer B Showing consists of a sulphide-bearing interval of garnetiferous chlorite-amphibolite schist which occurs along a contact between a granitic intrusive to the north and mixed metasediments to the south. A grab sample taken at the showing site returned 0.087 oz/ton Au.
W. Coombe described the host rock of the Studer B Zone as the same lean iron formation which hosts the Studer A Zone. A seres of irregular quartz veins and lenses occur within a pyrite-pyrrhotite-arsenopyrite-bearing argillite which has been labelled a 'lean' iron formation. R. Maxeiner mapped identical calcarous metasediments with interlayered carbonaceous and sulphidic argillites, in the Anglo Rouyn Mine area, as iron formation.
The Studer C Showing is hosted by a sulphide-bearing graphitic argillite horizon within a suite of mixed metasediments. W. Coombe suggested, in "Gold In Saskatchewan" that the C Zone, unlike the iron formation hosted Studer A and B Zones, consists of mineralized irregular quartz veins and stockworks within highly deformed felsic volcaniclastics (principally crystal tuffs). The average assay values from two grab samples taken at the site was 0.178 oz/ton Au.

- Exploration History
- 5/7/1993 The showing area was geologically mapped for the province of Saskatchewan in 1968 and 1971 by L. Forsythe.
The general showing area was first staked as MPP 1127 by Colray Resources Ltd. Colray completed limited work on the property, but no work was completed in the immediate showing area.
Vern Studer staked the immediate showing area as CBS 7381 (April 20, 1983) and immediately transferred the claims to Durama Enterprises Limited.
In 1985, Durama Enterprises completed ground EM and magnetic surveys and follow-up anomaly checking on CBS 7381 and adjoining CBS 7380 (AF 73P06-0104).
Between 1985 and 1986, Durama completed further geophysical surveys, prospecting, and basal till sample surveys on CBS 7381 and 7380 (AF 73P06-0105). While completing the prospecting, the Boundary Showing was discovered on CBS 7381.
In 1986, Durama completed an airborne INPUT and magnetic survey over adjoining CBS 6158 (AF 73P06-0108). Tracker Exploration completed reconnaissance program of geological mapping, ground EM and magnetic surveys, and trench sampling on CBS 6158 (AF 73P06-0116) and M.W. Thomas geologically mapped the showing area at a scale of 1:20,000 for the Saskatchewan Geological Survey.
Between 1986 and 1987, Durama completed further prospecting, rock, soil, and basal till sampling, and ground EM and magnetic surveys within CBS 7381 and 7380 (AF 73P06-0121).
In 1988, Durama completed ground VLF-EM and magnetic surveys on the Lynx grid (AF 73P06-0129). Durama also completed prospecting, stripping, trenching, and rock sampling of previously located geochemical gold anomalies (AF 73P06-0130). No significant values were returned.
In 1989, Durama Enterprises completed further reconnaissance mapping and prospecting (AF 73P07-0292). This work resulted in the discovery of the mineralization which constitutes the Studer B Showing and the Studer C Showing.
On 20 February 1990, Durama transferred the claims to Homestake Canada Ltd. In this year, they completed prospecting and rock sampling in the general showing area and an airborne VLF-EM and magnetic survey which covered the showing (AF 73P-0017).
