White Canyon Uranium Limited ASX announcement 20 October 2009 WHITE CANYON AGREES TO SELL DEVELOPMENT MATERIAL TO MAJOR US URANIUM PROCESSOR DENISON MINES US-focussed uranium company White Canyon Uranium Limited (ASX: WCU) has reached agreement with major North American uranium producer and processor Denison Mines Corp.

(TSX: DML, NYSE AMEX: DNN) to sell to Denison all material produced during the development stage of White Canyons Daneros uranium mine in South Eastern Utah through its Ore Buying Program. The sale of the material generated from the development activities at Daneros is key to White Canyon building a lasting relationship with Denison as it is a requirement of Denison that companies sell the initial production from development activities to their mill, so as to allow Denison to derive critical processing parameters in regard to the Daneros mineralisation and how best to treat it through their mill in the future. At the conclusion of this initial agreement, it is expected Denison will have all required information to enable the finalisation of a long-term treatment agreement between Denison and White Canyon. The development of twin declines at Daneros commenced in July 2009 and while progress has been slower than anticipated, the main access decline has progressed passed 700 (planned 900 -- 1000) and the mineralisation may be reached at the end of this month.

The mineralisation will be mined utilising room and pillar methods.

To achieve optimal production flexibility in terms of production tonnage and grade access to the mineralisation is required to be developed along the north south axis of the mineralisation.

This planned development will also expose the known edges of the drill defined mineralisation allowing underground exploration to proceed.
