Exploration History

7/29/1988 The Cinch Lake Mine began as a series of 4 showings occurring along a straight line between Cinch Lake and Guts Lake. The showings are spaced over equal intervals along a distance of 1,800 feet (548.6 m). The Cinch Lake Mine and 'River Zone' will be described first. The property covering the mine was first staked in 1948 for C. Swenson, who sold it in 1950 to Cinch Lake Uranium Mines Ltd. From 1951 to 1953, the property was examined in detail by the Mining Corporation of Canada Ltd., and 65 diamond drill holes for a total footage of 13,752 feet were drilled over a few small highgrade showings outlined just south of the Crackingstone River. In 1955, Cinch Lake Mines Ltd. discovered a minor pitchblende occurrence, named the B Zone, between the Cinch Mine and the River Zone. The showing was trenched and drilled between 1955 and 1956. In October 1954, Cinch Lake Uranium Mines Ltd., was re-organized to Lake Cinch Mines Ltd. and controlled by Violamac Mines Ltd., and by late 1955 an additional 22,500 feet of diamond drilling in 65 holes were done by Lake Cinch on the main radioactive zones. Results warranted the sinking of a vertical production shaft. The shaft was started in late 1955 and sunk to a depth of 548 feet (167 m). Two levels were established. Shipments to the Lorado Mill commenced in May 1957. In 1958 the shaft was deepened to 867 feet (264.3 m) and again in 1959 to 1,096 feet (334.1 m). By then four new levels had been established and lateral development on all six levels had been completed. On 26 March 1960, the production stopped and in May 1960 the mine was closed. Proven and probable reserves for the deposit were released at the time of closure. The ground covering the River Zone was restaked in 1965 and acquired by Enex Mines in 1966 when additional diamond drilling was done. This resulted in outlining two main veins in this zone, which is situated 1,200 feet (365.8 m) due west of the Cinch Lake Mine site. The major portion of this deposit is not connected to the mine workings. In 1969, the Enex group merged with Lake Cinch Mines under the name Gardex Mines for the purpose of developing the two properties jointly and using the Lake Cinch shaft. In July 1974, Eldorado purchased the property from Gardex and carried out an exploratory drill program over the next 15 months. Eldorado optioned these properties to New Joburke, who took the option in 1976, and through its wholly owned subsidiary, Mining Corporation of Canada (1964) Ltd., would be the mine operator and would play a key role in financing a $6 to $7 million project. It was proposed to explore and develop the River Zone, or Enex Zone, by an adit and decline to a vertical depth of 300 feet (91.4 m) below surface by trackless mining methods and equipment. The ore was to be treated and concentrated by Eldorado in its Beaverlodge Mill. The ore reserves for the deposit and for the Lethbridge Zone (or the combined 03 and 04 Zones): located just to the west of the River Zone were released. In August of 1977, New Joburke changed its name to Cenex Ltd. At this time, the deposit proven, probable, and possible ore reserves Enex property were re-calculated using data collected from the 1975 to 1976 drill program and and the amount of ore remaining in the Cinch Lake Mine was re-calculated. The River Zone was only examined underground on the first level of the mine during the operations of the Cinch Lake Mine. Because such good tonnages were outlined between 1975 to 1976, Eldorado over this zone and the adjacent Cinch Lake property, an adit, as mentioned above, was to be collared and mining of the ore was to commence by 1 May 1977. New Joburke through its subsidiary Mining Corporation of Canada (1964) Ltd. was to be the operator of this mining exploration, development and production work. In 1978, Cenex Ltd purchased the properties. A 2,500 m (8,202.1 ft) spiral decline was driven to 375 ft (114.3 m) vertical depth on the 03 Zone (1,500 ft (457.2 m) west of the shaft). Between 1978 and 1979, an ore sorter was installed and ore was trucked to the Eldorado Mill. In February 1979, a fire destroyed the powerhouse. Working capital became short and Cenex was placed in receivership. Mining ceased in October of 1979. In 1980, A. Frame Contracting purchased the minesite and stockpiled ore.

Reserves and/or Resources

1979-09-06 The Lethbridge Zone contains 15,000 tons grading 8.4 lb/ton U3O8 in the 03 Zone below the 500 foot level. Summary: Lethbridge Zone: Historic reserve (unspecified) of 15,000.00 ton - Uranium: 15,000.00 ton @ 8.4 lb/ton 1977-08-01 300,000 tons of ore which contain about 1,200,000 lbs U3O8 (included ore left in the Cinch Mine), of which 600,000 lbs on the Enex property are classed "fast pay". This is calculated to 300 feet on the Enex property and 1,000 feet at Cinch. Summary: Historic reserve (unspecified) of 300,000.00 ton - Uranium: 1,200,000.00 lb 1976-01-01 300,000 tons of ore grading 0.2% U3O8 (after 39% dilution) to the 1,000 foot level in the Cinch Mine and to the 300 foot level on the River Zone. Summary: River Zone: Historic reserve (unspecified) of 300,000.00 ton - Uranium: 300,000.00 ton @ 0.2 % 1960-05-01 (at mine closure) Proven reserves: 32,473 tons with an average grade of 0.196% U3O8. Probable reserves: 150,000 tons with an average grade of 0.23% U3O8. Summary: Historic proven reserve of 32,473.00 ton - Uranium: 32,473.00 ton @ 0.196 % Historic probable reserve of 150,000.00 ton - Uranium: 150,000.00 ton @ 0.23 %
