Audited Financial Statements for December 31, 2004

The Company finalized its audited year end statements for the year ended December 31, 2004. A final copy of these statements can be found on www.sedar.com. While there were no changes to earnings from those announced previously on March 3, 2005, there were changes to the Company's working capital position. On the financial statements that accompanied the March 3, 2005 press release, the Company disclosed that working capital was approximately $28.6 million for the period ended December 31, 2004. The final audited financial statements for the same period disclose working capital of approximately $26.2 million.

Quarterly Production

Recupere Sol Inc.

The Company processed approximately 3,700 tonnes at its facility in Saint Ambroise, Quebec in the quarter or approximately 1,800 tonnes less that it had reported in its press release of March 3, 2005. A later than anticipated start up of the facility along with material that needed to be processed at a lower rate were the primary drivers of the reduced volume.

Quebec Preliminary Notice

The Company and the Quebec Ministry of the Environment continues to work cooperatively to develop an action plan regarding the levels of dioxin and furan. This is a long process and it is expected that the discussions will be completed during the next quarter.
