Revett Minerals Rock Creek MPDES Permit -- Judge Sherlock Ruling; ''This, of Course, Does Not Mean the Proposed Mine Cannot Go Forward''

SPOKANE VALLEY, Wash.--(CCNMatthews - Mar 29, 2006) -

Despite claims to the contrary by groups opposed to Revett Minerals Inc.'s (TSX:RVM) Rock Creek Mine, a District Judge's ruling Friday that said while one component of the mine's water discharge permit needs to be "reworked," the Judge concluded "This, of course, does not mean the proposed mine cannot go forward."

On the 24th of March, Montana District Court Judge Jeffrey M. Sherlock ruled on Plaintiffs' motion for summary judgment in a lawsuit between a number of environmental groups and the Montana Department of Environmental Quality (DEQ). The lawsuit challenged the validity of the Montana Pollution Discharge Elimination System (MPDES) Permit which regulates the discharge of water from five outfalls at the Rock Creek Mine. The court ruled in favor of the company denying summary judgment on allegations that the Permit violated the Montana Water Quality Act (Act) and Montana Constitution (Constitution) at outfalls 001 and 004; however, on a third issue the court found violations of the Act and Constitution with respect to Outfall 2. The ruling did not impact four of the five outfalls. Revett had previously recognized the error in the original permit and began working with the Montana Department of Environmental Quality (DEQ) this past January to revise and update the discharge permit, including the outfall the judge said needs to be reworked.

"Well before Judge Sherlock's ruling, we began working with the DEQ through the normal review process to address this very matter," Revett's President and CEO Bill Orchow said. "The best way to permit and operate an environmentally sound mine is to constantly be looking for ways to improve every aspect and that's exactly what we're doing," he said. Orchow added that while each outfall within the MPDES permit is important, the one Judge Sherlock said needs modification is for the mine's tailings facility, which will not be needed until after the mine begins operating; the permits needed for more immediate activities such as the evaluation adit were not affected.

Revett is also expecting a draft of the new Biological Opinion for the project to be issued soon. Mr. Orchow further states, "We look forward to completion of the Biological Opinion and implementation of the mitigation plan with respect to recovery of the grizzly bears and protection of the bull trout within the Cabinet Yaak Ecosystem. The many years of study and careful planning will provide a sound basis for moving forward with the development of the Rock Creek Project."
