Geological Age: Paleoproterozoic
Dec 07, 2005 (M Hailstone) - The deposit is hosted within north west trending paleochannels of uraniferous pyritic quartz pebble conglomerates located in a basal memberof the Matinenda formation.
Dec 07, 2005 (P Beach) - The main orebody (Denison Reef) occurs from 0 to 180 feet above the Early Precambrian basement and 210 to 230 feet below an argillite layer. It is a tabular-shaped mass covering a projected surface area of 8000 feet by 14,000 feet. The ore zone averages 16.7 feet thick and strikes S65E with an average dip of 19 S. The ore zone is composed of two layers known as the A and B Zones. They average 8 feet in thickness. The average depth of the ore zone is 1000 feet at the north end and 3000 feet at the south end. The C Zone above the A and B averages 6 by 100 feet in size. The D and E Zones are conglomerate beds 50 and 70 feet below the argillite. The ore-bearing conglomerate is a uranium-bearing oliogomicitic quartz-pebble conglomerate. Economic Features: From 1961 to 1980, production from the Denison Mine was 34,376,100 tons of ore, from which 41,297 tons U308 were recovered for an average grade of 0.12 percent U308.
