RB2 (Red Block 2)

Cinch/Cenex Mine

The Cinch Lake Mine began as a series of four showings occurring in a straight line between Cinch Lake and Guts Lake. The showings are spaced at sub-equal intervals over a distance of 1,800 feet (548.6 m). In October 1954, Lake Cinch Mines Ltd. performed extensive exploration whose 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 of mined ore to the Lorado Mill commenced in May 1957. Production, under a succession of operators, continued until 1979 when a fire destroyed the powerhouse.

Production

From May 1957 to May 1960, 125,205 tons of ore were shipped. This produced 661,257 lbs U3O8 (Saskatchewan minerals deposits index SMDI # 1425a). Between 1978 and 1979, the Cenex Mine produced 712,375 lbs U3O8 and the Leadridge Zone (combined Zones 3 and 4) produced 855,429 lbs U3O8 (482,000 lbs concentrates) (Saskatchewan minerals deposits index SMDI # 1425a).

Leadridge Zone

While operating, Cenex Mines Ltd proposed to access the Leadridge Zone from the Cenex Mines underground operations. This was never completed prior to operations closure due to the power house fire. Cenex diamond drill hole U-79-80 intersected a six foot section which averaged 1.1% U3O8 (Saskatchewan minerals deposits index #1425a). The Leadridge Zone of mineralization is located approximately 400-600 feet northeast from the Cenex mine and is situated between 25 and 300 feet from surface. The zone occurs on the footwall side of the Crackingstone River fault and on the hanging wall of a structure known as the Leadridge fault. The mineralized zone has a rough cylindrical form with a diameter ranging from 100 to 200 feet and extends over a length of approximately 400 feet. The zone trends in an E-NE direction and is cut off by the Crackingstone River fault on the southwest. Beck (1969) describes the Leadridge Zone as being located at the faulted contact between mylonitized quartzfeldspar gneiss and quartz -feldspar chlorite schist striking 045°. Scattered pitchblende veinlets accompanied by hematite are found in the fault zone for a length of 1100 feet.

Chance Lake

The Chance Lake Zone is located 0.25 miles southwest of Chance Lake. In 1968 Tobe Mines channel sampled the mineralized zone which indicated a narrow mineralized shoot 230 feet (70 metres) long grading 0.18% U3O8 across 2.1 feet.

Early Bird Claims

The Early Bird claims have seen several operators from the time of initial discovery of the surface expression. The operators (some under option only and some as direct owners) in chronological order were: Amax, Early Bird and Eldorado Nuclear Ltd.

The Early Bird property borders immediately north of the Jam group of claims approximately one half mile NW of the Cinch adit. The area overlies the strike continuation of the surface exposure of the Main Ore Fault of the Cinch mine. The two principle showings of interest were numbered zone 04-12 and the 04-14 by Early Bird Mines Ltd. The 04-12 vein (Boundary Zone) consists of a narrow, low grade, well-defined fracture zone trending N70°E and dipping 40° -70°NW. The zone is a gently sinuous, sheared contact between siliceous mylonite to the north and chlorite schist and melanocratic gneiss to the south.

Diamond drilling by Eldorado Nuclear Ltd in 1974 (ddh's J74-5 to J74-8) indicated a continuous zone of mineralization. Twenty-two percussion holes were drilled as a follow-up but the results were not considered to be of economic importance at that time. The shear zone consists of grey to red gneisses and chloritic gneiss. Earthy red hematite, chlorite, and graphite were noted throughout the zone of shearing, occurring along slips and as stringers. Eldorado's vertical drill holes, drilled to test the radioactive zone, encountered only weak mineralization associated with a fault zone and some steeply dipping fractures. The high grade intersection reported in EB-15 was not confirmed and it was concluded that the high grade zone was a local situation occurring at the junction of two weakly mineralized veins. The northeast extension of the 04-14 zone was tested in 1975 with four cored holes (EB50-53) totaling 1,302' and by eight percussion drill holes totaling 723'. Numerous radioactive intersections were recognized in both the footwall and hanging wall of the 04-14 shear zone. These were interpreted as being narrow, gently dipping cross fractures. The depth potential below this mineralized zone was tested in 1976 with three vertical diamond drill holes (EB82-84) totaling 1,717'. Eldorado confirmed low grade and erratic mineralization and recommended no further drilling.

Amax Athabasca: Uranium Mines Lake Cinch Extension Drilling Geological Setting

NE-trending sequence of paragneiss enclosing a strike-fault, believed to be an extension of the Main Ore Fault at Lake Cinch Mine. Mineralization and dimensions: Best intercept of 0.3%U3O8 over 5 feet (1.6 m). Diamond drill holes from hanging wall of Lake Cinch Extension Fault into wedge of mylonitized gneisses gave intersections. Correlation between holes was poor and continuity of mineralized zones not proven. Beck states: “In view of the structural similarity of the locality and the Lake Cinch mine area a systematic program of diamond drilling based on a careful structural analysis of the area is justified” (Beck 1969) Pg 87 Map 126B, 54.

Mor Claims

In 1951, Gateway Gold Ltd. drilled a hole on the Mor claim S5484 that extended into the deformation zone of the Black Bay fault approximately one mile south west of Cinch Lake.  This hole DDH #1 was drilled at N45°W with a dip of -45° (320 feet) intersected a radioactive zone of 94.3 ft. with an average grade 0.025% U3O8 including higher grade intersections.

Mokta Claims

A northeast trending outcrop of felsic paragneiss is bounded on the southwest by a northwest trending, overburden-filled depression presumed to contain a cross fault. A trench at the edge of the outcrop exposes a breccia-mylonite zone which strikes N45°W and dips 75° SW.  The breccia is cemented with quartz and pink carbonate and pitchblende occurs as a thin coating to fracture surfaces within a 45 by 10 foot area. (Beck 1969 p88).

Six bulk samples were taken at ten foot intervals along the zone. Two of these were of ore grade, assaying 0.25% U3O8 and 0.29% U3O8, but the average tenor of the other samples was only 0.04%. Four of the holes put down to test the showing intersected zones of weak to moderate radioactivity.

Amax Athabasca: Uranium Mines Ltd. Showing      

No. 50-CC1-128C

The showing lies approximately 350 feet northeast of showing 50-CC1-128 and consists of a fracture zone that trends N40°E and dips 75° SE.  On surface the zone has been exposed for a strike length of about 60 feet by three trenches; to the northeast the fractures thin disappear but to the southwest the zone passes beneath overburden. The fracture zone is at or near the contact of felsic quartz feldspar gneiss with more mafic quartz feldspar biotite gneiss. A lens shaped body of mylonitized and brecciated gneiss occurs on the footwall side of the fracture zone. The breccia body is thirteen feet wide in the center. The breccia zone is highly radioactive with abundant uranium stain especially in the vicinity of individual fractures and chlorite rich segregations.

Nine drill holes were put down to test the showing in 1951 and six of these intersected ore grade material indicating a small ore shoot 350' long grading 0.27% U3O8 across an average width of 3.9 feet. In 1968 Mokta Exploration (Quebec) Inc. conducted a percussion drilling program on these showings. Nineteen holes at an average depth of 150' to 250' were drilled at a spacing of 100 feet. These outlined a small 300 foot zone containing approximately 17 tons of uranium metal (J Bernazeaud 1968). The estimates of reserves are not compliant with the 43-101 requirements under sections 1.3 and 1.4 however management believes the estimate of reserves are relevant and did comply with the standards and industry practices at the time of reporting.
