Exploration History

8/2/1989 The Cu showing on Moose Point was noted in 1909 by W. McInnes of the G.S.C. In 1915, Richard and Gordon Hall in 1915 staked the first eleven claims over the showing. In 1919, the claims were transferred to the Lac la Ronge Mining and Development Company Ltd. In 1928, the Consolidated Mining and Smelting Company of Canada Ltd. Optioned the ARMISTICE-ALLIES-LIBERTY-PEACE-DREADNOUGHT claims. In 1929, trenching and drilling of 12 holes totalling 8794 ft on an extensive gossan zone was reported (AF 73P07-0122). The option was dropped in 1929 and the claims were allowed to lapse in 1950 to 1951. The property was restaked in 1951 to 1953 as the WADEN, A.G., CU, AH, MOORE and PIPE Groups; the claims were optioned by Anglo-Rouyn Mines Ltd. And later acquired by the company. Extensive geological mapping, trenching, sampling, and the drilling of 50 holes totalling 12,207 ft was reported. A sizable ore body was outlined parallel to and 450 m southwest of A Lake; the company embarked on an underground development program in 1955. By 1956 a vertical shaft had been completed to a depth of 544 ft with levels at 175, 280, 392 and 504 ft. Lateral development totalled 422 ft on the 392 ft level and 2281 ft on the 504 ft level. Total indicated reserves, which were based on work to the end of 1956 when activity was suspended, were released at this time. In 1956, the DMR investigated an aeromagnetic anomaly near the minesite. In 1957, further drilling, a total of 21,941 ft in 27 holes were reported - the property remained inactive until 1953. The property was enclosed by Mineral Lease 5002 on 6 June 1962. In 1963, 144 claims adjoining the existing mineral lease were staked and were amalgamated under ML 5088. Exploration work was carried out by Rio Algom Mines Ltd. In 1964 approval was granted for a 6.5 mile (10.5 km) road connecting the property with the La Ronge highway and Anglo Rouyn decided to operate a mine on the property at a production rate of 900 tons per day, the product to be shipped to Flin Flon by truck for smelting. In 1964, the La Ronge Mineral Syndicate drilled one hole on the FLO no. 4 claim to a depth of 3282 ft 0.4 miles northwest of the Anglo Rouyn ore zone in an attempt to intersect the ore bearing horizon. Continuous pyrite, possible the halo of the ore zone, was intersected in the 2400 to 2050 core interval. Assays gave 0.16 oz./ton Ag, 0.01 to 0.04 oz./ton Au and 0.06% Cu. In 1964 to 1965, a further 33 holes totalling 25,546 ft were drilled on the Anglo Rouyn property (AF 73P07-0099). In 1965 construction of the mining and milling plants began, the old shaft was dewatered and deepened to over 800 ft, and lateral development was begun. The mill was completed in 1966 and the first shipment of concentrates was made in February. Revised reserves figures were released at this time. In 1965, a small open pit was developed on the A Zone to supplement the ore taken from underground. Between 1965 and 1967, the A Lake pit produced 102,000 tons of ore averaging 1.72% Cu. Between 1969 and 1970 when the pit bottom intersected the upper underground mine level. In May 1969, a pit was completed 1.5 km to the northeast at C Lake. This pit produced a total of 317,000 tons of ore. Total underground development between 1965 and 1968 was 44,537 ft. Between 1969-70, a 600 m long decline was driven southwest from the lowest mine level (level 5) to access additional ore at the southwest extension of the A Zone. A further decline was driven from C Lake to the east. This decline became operational in 1970. In 1971, ore came from the A and B zones by shrinkage mining and from the C Zone using trackless equipment. The Anglo-Rouyn mine horizon was mined over a strike length of approximately 3.5 km (2.2 miles) (AF 73P06-0136). Milling began in January 1966 and ceased in 1972. During this 7 year period, a total of 62,227,107 pounds Cu, 309,600 ounces Ag and 67,652 ounces Au were produced from 1,892,800 tons of milled ore. At the time of closure, W. Pearson estimated there were left unmined (pillars) an additional 184,554 tons of ore that graded 1.74% Cu (AF 73P06-0113). In 1967, Riocanex conducted an IP survey and drilled 5 holes totalling 3811 ft on the northwestern shore of Ore Bay on the AG 1 & 2, MOOSE 1 to 4 and WADEN 15 & 19 claims to intersect the southwestern continuation of the Anglo ore zone. Sulphides were intersected in all holes, the best being in drill hole 292 which intersected sulphides assaying 0.3 to 2.20% Cu over widths of 3 to 5 ft over the entire 866 to 982 ft core interval. In 1970, ML 5002 and ML 5088 were consolidated into ML 5090. In 1973, Anglo Rouyn Mines, the sole mine owner, amalgamated to form Canadian Memorial Services Ltd. In 1975, the company changed its name to Arbor Capital Resources Inc. and applied to surrended ML 5090 in 1976. On 1 November 1983, ML 5090 lapsed following satisfactory cleanup and removal of buildings and mine equipment from the site by the owner. The area around ML 5090 was staked as CBS 7409 on 6 September 1983 by Rockspan Resources Ltd and claims S-106194 to S-106197 were converted to CBS 7244 on 1 November, 1983 by Kristo Gold Incorporated. Noranda Exploration Company Ltd. Completed diamond drilling (9 holes), geological mapping, soil sampling, sampling of old core and ground magnetic surveys over CBS 7244 (AF 73P06-0100). Noranda then dropped the option. Durama Enterprises completed a ground EM and magnetic survey on CBS 7409 in 1985 to 1986 (AF 73P06-0099, 0103, 0109, 0111) and airborne VLF-EM and magnetic surveys (AF 73P06-0099) in 1987. Lake sediment sampling and ground VLF-EM and magnetic surveys were also completed in 1986 (AF 73P06-0107). A joint venture agreement between Golden Dragon Resources Ltd., Rockspan Resources, and Richard Davidson completed prospecting, geological mapping and soil sampling in 1987 (AF 73P07-0010). In 1987, Durama completed prospecting ,soil sampling and ground HLEM on CBS 8946 (AF 73P07-0253). In 1986, Durama had completed ground VLF-EM and magnetic surveys over the tailings pond area and sampled the tailings pond (AF 73P07-0241). The portion of the tailings pond covered by Durama Enterprises CBS 8946 was re-covered by S-101772 when the claim was reduced. Between 1987 and 1988, Durama completed 14 wacker till holes and 13 sonic drill holes to sample the tailings (AF 73P07-0305). Between 1987 and 1994, Kristo Gold Inc. completed a preliminary feasibility study to determine the economic viability of reprocessing the mine tailings to recover gold and copper (AF 73P06-0155). The study determined that the project would be viable. It was estimated that 72% of the contained gold and 50% of the contained copper would be recovered. Between 1988 and 1989, Tusk Resources Inc. and Kristo Gold Inc. completed geological mapping, prospecting and ground geophysical surveys. The program identified a previously unknown likely western extension of the Anglo Rouyn orebody (AF 73P07-0286). On 22 June 1989,Durama Enterprises converted CBS 8946 to S-101772. In 1990, Kristo Gold and Trimark Resources optioned the property and completed geological mapping, prospecting, stripping, trenching and sampling on the minesite grid (AF 73P07-0306). On 13 October 1992, Kristo Gold commenced operating a pilot plant to extract gold from the mine tailings pond. 4,300 tons of tailings (including 880 tons from a 500 ft long by 2 ft wide by 25 ft deep trench cut in the tailings) were processed and reduced to 25 pounds of superconcentrates, 21 tons of concentrates, and 61 tons of middlings. The superconcentrates assayed 35% Au and 25% Ag. A 122.878 oz gold bar and a 97.5 oz silver bar was produced from the superconcentrates. Significant magnetite in then tailings interfered with the recovery of precious and base metals. On 10 September 1995, Kristo Gold Inc. submitted an environmental assessment review to reprocess the mine tailings. The reserves for the sampled portion of the tailings, calculated based on a specific gravity of 2.47, were published 10 September 1995. Mining of only those tailings within the property boundaries which could be accessed by a Neuman dredge was proposed. The recovered tailings would be screened then concentrated with magnetic and gravity (Krebs D10LB cyclones) separation. Final cone tailings would be disposed of in the underground workings and open pit. Magnetite product would be stored for possible sale. Approximately 75% of the old tailings would be removed from the floors of lakes currently containing tailings. Concentrated ore would be trucked to an existing mill for processing. On 12 September 1999, Rod Spooner (for Kristo Gold Inc) staked the tailings pond area as S-106194 to S-106197 as part of a reduction of CBS 7244. On 20 July 2004, S-106197 was converted to ML 5524. In 2004, Kristo Gold Inc constructed a magnetic-gravity separator plant on site and conpleted two feeder lines to pump tailings from the tailings pond to the separator plant. The plant is configured to process 250 tons per hour and is expected to recover 70% to 80% of the Au and 50% of the Cu from an estimated 1.3 million tons of tailings (average grade of 0.016 oz/ton Au and 0.19% Cu). The resulting concentrate can be directly smelted to bullion. Total production from the tailings is expected to be 14,000 oz Au. In 2004, Durama Enterprises sampled that portion of the Anglo Rouyn tailings pond they had covered by S-101772 (AF 73P07-SW-0358).
