JANUARY 28,12009

Discharge Permit DP-71

Summary of Activities

This report presents the results of the monitoring and sampling requirements

associated with discharge permit DP-71 for the period encompassing the 4th

quarter of 2008. DP-71 permit renewal was approved on December 1, 2003 and

monitoring requirements were expanded from previous monitoring commitments

listed in the permit. This has resulted in acquiring data that was not obtained in past

monitoring programs.

_Activi-ties-associated with the Section 4 lined evaporation ponds consisted of

continued transporting of material to Pond 2 for final disposal. Hauling of sediments

was initiated in December 2005 following construction of a highway overpass. As of

November 30, 2007, 100% of the estimated pond sediments have been relocated to

the disposal cell at the main mill facility. There were no spills or related problems

with the lined ponds during the reporting period.

All wells associated with the permit were dry or contained insufficient water for

sample collection except for two wells. These wells were MW-22 and MW-32.

Laboratory/analytical results for the quarterly sample events were provided by ACZ

Laboratories. A table summarizing the data is attached and copies of the

laboratory reports are included with this submittal.

Time versus concentration plots for constituents chloride, sulfate, TDS, and a

hydrograph for MW-22, MW-26, and MW-32 are attached. Since all other wells

continue to be dry, Rio Algom wishes to incorporate the hydrographs for the other

wells associated with DP-71 that were included within the April 3, 2006 submittal.

Due to the lack of any water in the alluvium in the Section 4 Pond area,

development of a potentiometric map for the alluvium was not undertaken. Since

mine dewatering from mines northeast of the Section 4 Ponds ceased in 1985, the

alluvium in the vicinity of the Section 4 Ponds has drained, which is reflected in the

historical water level data obtained from the monitoring wells associated with the

Section 4 Ponds.

Practical Quantitation Verification standard

Serial Dilution

Blanks Verifies that there Is no or minimal contamination in the prep method or calibration procedure.

Control Samples Verifies the accuracy of the method, including the prep procedure.

Duplicates Verifies the precision of the instrument and/or method.

Spikes/Fortified Matrix Determines sample matrix interferences, if any.

Standard Verifies the validity of the calibration.

B Analyte concentration detected at a value between MDL and PQL The associated value is an estimated quantity.

H Analysis exceeded method hold time. pH is a field test with an immediate hold time.

U The material was analyzed for, but was not detected above the level of the associated value.

The associated value is either the sample quantitation limit or the sample detection limit.

Don Sweeney:

Enclosed are the analytical results for sample(s) submitted to ACZ Laboratories, Inc. (ACZ) on January 05,2009. This project has been assigned to ACZs project number, L73780. Please reference this number in allfuture inquiries.

All analyses were performed according to ACZs Quality Assurance Plan, version 12.0. The enclosed resultsrelate only to the samples received under L73780. Each section of this report has been reviewed and approvedby the appropriate Laboratory Supervisor, or a qualified substitute.

Except as noted, the test results for the methods and parameters listed on ACZ's current NELAC certificateletter (#ACZ) meet all requirements of NELAC.

This report shall be used or copied only in its entirety. ACZ is not responsible for the consequences arisingfrom the use of a partial report.

All samples and sub-samples associated with this project will be disposed of after February 15, 2009. If thesamples are determined to be hazardous, additional charges apply for disposal (typically less than$1 0/sample). If you would like the samples to be held longer than ACZ's stated policy or to be returned, pleasecontact your Project Manager or Customer Service Representative for further details and associated costs.ACZ retains analytical reports for five years.

If you have any questions or other needs, please contact your Project Manager.

Scott Habermehl has reviewedand approved this. report.
