Pre-Feasibility Study

Low operating cost of <18/lb at high recovery (>92%).

An independent PFS Level Engineering Study completed in March 2013. The PFS highlights are as follows:

Project Location South Eastern USA
Plant Capacity 1 million stpa P2O5
Potential Uranium Production 0.88 million lb U3O8 per annum
Facility Life >25 years
Uranium Recovery 92%
Uranium in Phosphoric Acid 165mg/L U3O8
Operating Cost < US$18/lb U3O8
Capital Cost US$156 million *


* Note, depending on the (normally) available infrastructure at the development site, additional capital may be required (estimated at up to US$9 million for a plant in south eastern United States).

In PhosEnergy’s opinion, the results of the PFS put the PhosEnergy Process in the bottom quartile for operating costs of all uranium production worldwide and at a considerable cost advantage over the bulk of new projects likely to come online over the next 5 to 10 years.

Intermediate product transport for toll-milling accounts for a substantial portion of the estimated total cash operating costs outlined above. This represents a significant opportunity for cost-structure improvements both through improved contractual transport arrangements and contained uranium concentration of the intermediate product.

Other opportunities exist in the refinement of reagent usage and power consumption as the development progresses.

Estimated operating costs do not include corporate office, marketing and downstream phosphate processing costs which may be incurred.

Several opportunities for further optimising equipment, structural and civil capital components are under review and will be incorporated into subsequent studies.
