Dear Mr. Myers,

Please find attached the 4th quarter groundwater monitoring report forthe Section 4 lined evaporation ponds at the Ambrosia Lake mill facility for theabove referenced discharge permit. This report includes the quarterly reportingrequirements as per DP-71.

If you have any questionsat 287-8851.

or need additional information, please call me

4th Quarter 2007

January 7, 2008

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 2007. 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.

Activities associated with the Section 4 lined evaporation ponds consisted of a

contractor continuing to consolidate the pond sediments prior to transporting the

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 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.

Analysis exceeded method hold time.

Poor spike recovery accepted because the other spike in the set fell within the given limits.

High Replicate Error Ratio (RER) accepted because sample concentrations are less than 10x the MDL.

No nuclides detected above the Lower Limit of Detection (LLD)

High blank data accepted because sample concentration is 10 times higher than blank concentration

QC is out of control. See Case Narrative.

Poor spike recovery is accepted because sample concentration is four times greater than spike concentration.
