- Geological Details
- Pleistocene overburden 50-100 m thick overlies the Patterson Lake South Property. Phanerozoic Mannville Group shales, mudstones, sandstones and coal underlie the Pleistocene glacial sediments, and drilling to date supports that the Athabasca group is not present in the project area. Beneath the Phanerozoic rocks and above the rocks of the Precambrian Taltson Domain is regolith and where strongly developed is strongly hematite stained followed by a chloritized zone. The uranium deposit is considered shallow, basement hosted, structurally controlled and high- grade. Discovery hole, PLS12-022 was a 10 m step out to the NW of PLS12-016 and targeted the middle southernmost conductor within the Patterson Lake Corridor, the axis of which cuts through a resistivity low anomaly. Geochemical results include: 8.5 m @ 1.07% U3O8 from 70.5 to 79.0 m (including 2.5 m @ 2.63% U3O8 from 74.0 to 76.5 m). Background to anomalous concentrations of 'pathfinder' elements include 157 ppm Co, 2210 ppm Cu, 802 ppm Mo, 463 ppm Ni, 1500 ppm Pb and 1040 ppm B.

Sedar webpage: URL<www.sedar.com/> [Oct., 2015].) Assessment work file MAW00509 reported on the fall of 2012 and winter of 2013 drill programs. In addition to discovery hole PLS12-022, drill hole PLS12-024 had the most extensive high-grade intersection from the fall program of 1.78% U3O8/18.0 m from 65-83 m. The winter 2013 drill program focused on expanding the areas of known high-grade mineralization in three distinct zones spanning a strike length of about 850 m. Drill hole PLS13-059 has the most extensive high-grade intersection, returning two mineralized intervals including 17.78% U3O8/9.5 m within 8.57% U3O8/20.5 m. 2013-14 drill program of 37 step-out holes along the east-northeast trending Patterson Lake Corridor away from the Triple R deposit for a total of 10,911 m (MAW01976). A 2.63 km strike length with 4 separate deposits were known at that time.

Fission has published a Feasibility Study outlining the potential for the Triple R to become one of the lowest cost uranium mines in the world and has also submitted its draft EIS to the regulators. The Company is on schedule to continue developing PLS through the permitting and licensing phase and on to construction and production by 2029.

Fission Uranium Corp. Reported results from a drill program for the R1515W zone at its Patterson Lake South property, noting that all holes intercepted mineralization. The R1515W zone is a component of a number of mineralized zones that make up the western region of the Triple R deposit. Fission has now entered a detailed design phase for the Patterson Lake South project, which will include the R1515W zone.

RPA updated the Mineral Resource estimate for the Triple R deposit using drill hole data available to July 28, 2015 (table 1-8).
Estimated block model grades are based on chemical assays only. Gold grades were also estimated. Mineral Reserves have not been estimated for the Triple R deposit.
