Summary:
Eagle Point Uranium deposits are located on the eastern edge of the Athabasca Basin, and are part of the Rabbit Lake Uranium district, which also includes the Rabbit Lake and Collins Bay deposits.
Uranium mineralization at Eagle Point occurs in lenses, pods, and veins which are both concordant and discordant to the metamorphic stratigraphy, and are distributed through a stratigraphie thickness of at least 300 m.
The mineralization at Eagle Point is structurally controlled, occurring as fault- or fracture-fillings and as impregnations into altered paragneisses and pegmatoid rocks. The total strike length of mineralized rock is about 1000 m. The main mineralized zones generally have a total vertical width of approximately 90 m, in places ranging up to about 250 m. Mineralization extends to a vertical depth of at least 360 m below the present bedrock surface.
The Eagle Point deposits occur entirely within Wollaston Group rocks of Aphebian age. They are essentially structurally controlled, and are remarkably similar to each other in their simple mineralogy, consisting essentially of uranium oxide. Nickel, arsenic, cobalt, boron and other metals, which are characteristically present in typical unconformity-type deposits and which are contaminants as far as processing is concerned, are essentially absent.

Summary:
The Rabbit Lake mill is fed by the Eagle Point underground mine.
Ten primary circuits are used to produce yellowcake at the Rabbit Lake mill:
1. receiving;
2. grinding;
3. leaching;
4. counter-current decantation;
5. clarification;
6. solvent extraction;
7. gypsum precipitation;
8. uranium precipitation;
9. product drying and packaging; and
10. neutralization circuit.
