- The Tamar Showing or "Vein 23" is located approximately one half mile (0.8 km) north of Lower Fork Lake. The showing is 500 m (1640.4 ft) south of David Lake.
The area of the showing was first mapped by A. Morris in 1960 as lying on the contact between diorite and andesites and basalts. In 1984, D. Thomas identified the underlying rock units as mafic volcanic flows and hornblende biotite leucodiorite and monzodiorite with minor monzogabbro and gabbro.
More detailed mapping completed after the discovery of the showing indicates the showing to occur in a strong, persistent, 050°-trending, 80° northwest dipping shear zone, with a ribbon-like quartz schist texture, that cross-cuts the eastern contact between a north-striking band of carbonatized and chloritized mafic volcanic flows and the Star Lake Pluton. The 520 m (1706.0 ft) long and up to 24.5 m (80.4 ft) wide shear zone transects the contact between metavolcanics to the southwest and granodiorite-diorite to the northeast.
Pyrite and minor chalcopyrite mineralization occur within the shear zone in chloritized and carbonatized ground up shear rock, within quartz veins and lenses found within the shear zone and less commonly within sheared wall rocks. The shear zone, which is open-ended, has been intersected or exposed in pits and trenches.
Between 1960 and 1962, E. Partridge completed 20 drill holes to delineate the mineralization. Two drill holes 91 m apart and completed in 1961 intersected ore grade material and returned the following assays:

Trenches were reported and surface sampling returned values of 0.01 oz/ton over 4 ft and 0.76 oz/ton over 6.3 ft. Three chip samples were taken and returned the following:

Another drill hole completed in 1962 returned an assay of 0.71 oz./ton Au over 12.1 ft (from 124.7 to 136.8 ft depth) within chlorite biotite schist containing quartz stringers and a 1.5 ft quartz vein. Other diamond drill holes completed in the immediate vicinity returned very low assays which suggested that the mineralization was erratic.
A chip sample reported by Coombe in 1975 returned 0.08 oz./ton Au and 0.02 oz./ton Ag over 0.9 m.
In 1982, SMDC grab and chip sampled the showing. Ten samples taken from the volcanic wallrock returned up to 0.03 oz./ton Au. One chip sample returned 0.127 oz./ton Au over 5 m. Grab samples taken in 1983 returned:

- Exploration History
- 8/3/1989 The area underlying the showing was first mapped at 1:63,360 by A. Morris of the Saskatchewan government in 1960.
The area of the showing was staked by E.F. Partridge and Associates as the TAMAR series of 66 claims to cover the showing E.F. Partridge had located while prospecting for gold-bearing quartz in 1958. In 1961, five X-ray holes totalling 407.8 ft were drilled in the immediate vicinity of the Tamar Showing, and minor trenching and sampling was reported.
The property was optioned by Rio Tinto Canadian Exploration Ltd in 1962. The company implemented a program of geological mapping, digging 12 test pits and diamond drilling of 13 holes to total 2585.1 ft (AF 73P16-0005). Only one hole (hole T-10) returned interesting assays. The hole intersected 0.71 oz./ton Au over 3.7 m. The claims were allowed to lapse.
In 1975, W. Coombe examined the property and took several chip samples. The results are given above. In 1977, SMDC completed an INPUT and magnetic survey over the showing (AF 73P16-0022). On 12 January 1980, Claude Resources staked a portion of the showing as S- 98275 to S-98279 (TAMAR claims). The rest of the showing, including the discovery site, was covered by MPP 1112, which was issued to Golden Rule Resources Ltd. in the same year. In 1981, Energy Reserves Canada Ltd. optioned MPP 1112.
In 1982, SMDC entered into a joint venture agreement with Energy Reserves and subsequently novated into the Energy-Reserves-Golden Rule Joint Venture and took over operatorship of the property around the showing. The partnership completed a program of regional lake sediment sampling (AF 73P16-0037), and mapped and prospected the immediate showing area (AF 73P16-0038). In the same year, V. McCann restaked the showing as S-98275 to S-98279. In 1983, Energy Reserves Canada Ltd. sold their interest in MPP 1112 to Goldsil Mining and Milling Inc. Between 1982 and 1984, the partnership completed further mapping and prospecting on their portion of the showing. D.J. Thomas geologically mapped the showing area at 1:20,000 for the Saskatchewan Government. In the same year, Claude Resources purchased S-98275 to S-98279 from V. McCann and, along with Cameco and Shore Gold Fund, started a 3 phase exploration program on S-98275 to S-98279 (staked to cover the eastern portion of the showing). Phase 1 consisted of detailed IP, VLF-EM, magnetic, geochemical and geological surveys. Phase 2 was a drill evaluation of the Tamar Zone at depth and along trend as well as other targets dilineated by phase 1 exploration.
In 1984, the western portion of the showing within MPP 1112 was staked as CBS 7430 by Cameco. Cameco continued to map, prospect and sample around the Tamar Zone (AF 73P16-0065). Grab sample NR40-9083 returned 0.047 oz./ton Au, sample NR40-9088 returned 0.127 oz./ton Au and sample NR40-9091 returned 0.077 oz./ton Au. In the same year, Claude Resources completed detailed IP, VLF-EM and magnetic surveys and mapping and sampling over their portion of the showing.
In 1985, Cameco converted CBS 7430 to ML 5453. At this time, the deposit reserves were given (VSE 02/04/86).
In 1986, Cameco and Shore Gold Fund Inc. (made up of Starrex Mining Corporation Ltd. and Uranerz Exploration and Mining Ltd.) entered into an agreement with Claude Resources to acquire 66% of S-98275 to S-98279 (along with the Jojay property) for $2 million over four years (George Cross Newsletter of 23 July 1986). In 1986, Cameco completed ground VLF-EM and magnetic surveys over the TAMAR claims (AF 73P16-0069), ground VLF-EM and magnetic surveys and 3 drill holes (# FO86-1 to 3) over that portion of the Tamar Structure within ML 5453 (73P16-0074). and further prospecting, stripping and sampling over the Tamar Zone. The sampling returned up to 0.023 oz./ton Au. Twenty one drill holes (TA86-1 to 14 and FO86-4 to 10) were completed over the Tamar Zone (AF 73P16-0118). The best drill intersection encountered returned 0.527 oz./ton Au over 2.5 m. In the same year, a SMDC (66%)-Claude Resources Incorporated (34%) partnership re-sampled the Kahn 23 trenches and completed geological mapping and soil and bulk till sampling over the showing grid (AF 73P16-0127). This work located a parallel poorly mineralized structure 550 m to the east of the Kahn Structure which has been named the Kamp Structure.
Between 1986 and 1987, Cameco completed ground VLF-EM and magnetic surveys (AF 73P16-0121) and drill holes TA87-19 and FO87-11, 12 and 18 to 22 on their portion of the Tamar Zone (AF 73P16-0120).
In 1987, Cameco completed detailed geological mapping and rock, soil and bulk till sampling over that portion of the Blindman Lake south grid which covers the Tamar Zone (AF 73P16-0119). No significant values were returned by this regional sampling program. In the same year, a partnership involving Cameco (51%), Claude Resources Incorporated (34%), and Shore Gold Fund (15%) completed drill holes TA97-15 to 26, 30 to 33 and 35 to 47 on the Tamar Zone (AF 73P16-0145). At the same time, drill holes TA87-27 to 29 and 34 were completed on the Kamp Zone (550 m southeast of the Tamar Zone). The Kamp drilling failed to intersect significant values. In the summer of 1987, the Tamar Zone was stripped, trenched, geologically mapped and a bulk till sample survey was conducted (AF 73P16-0146).
In 1988, a helicopter-borne VLF-EM and magnetic survey was completed over the showing (AF 73P16-0135). In the spring of 1988, the partnership completed drill holes TA88-48, 49 on the Kamp Zone, drill holes KA88-50 to 53 on the C anomaly (between the Kamp and Tamar Zones), drill holes TA88-54 and 55 on the B anomaly (southewst end of the Tamar Zone) and drill holes TA88-56 to 58 on the E anomaly (350 m northwest of northwest end of the Tamar Zone) (AF 73P16-0147). Only drill hole TA88-49 intersected significant values.
