RIO ALGOM MINING LLC - AMBROSIA LAKE FACILITYDISCHARGE PERMIT - 71 (DP-71)

FIRST QUARTER REPORT 2013

This report presents the activities and results of the monitoring and sampling requirements associatedwith DP-71 for the 1st quarter of 2013. DP-71 permit renewal was approved on December 1, 2003and monitoring requirements were expanded from previous monitoring commitments listed in thepermit. This expansion has resulted in acquiring data that was not obtained in past monitoringprograms. In 2012, RAML submitted an updated application for DP-362 permit renewal that wouldinclude the DP-71 monitoring activities to New Mexico Environment Department, which is currentlyunder review.

Section 15A:Activities that included the remediation of the Section 4 lined evaporation ponds were conducted from2005 through 2009. There were no operations or soil removal activities conducted at the Section 4pond area during the 1st quarter of 2013.

Water was present in MW-32 and a sample was collected for analysis. Water was detected in MW-22and MW-23, but a sample was un-attainable due to insufficient depth of the water column. Theremaining wells associated with the permit were dry or contained insufficient water for sample.

Exhibit 1 presents the time versus concentration plots and hydrographs for MW-22, MW-23, and MW-32. Because of the deficiency of alluvial water in the Section 4 pond area, development of apotentiometric map for the alluvium is not practical.

Snow and or rain showers occurred on January 1st, 14 th, 26th, 28th, 29th & 30t", and snow flurriesoccurred on February 9th, 20e, 2 1st, and 24', and snow flurmes on March 2 "d.

Section 15B:Exhibit 2 presents a table titled Section 4 Monitoring Wells, Analytical Results and Water LevelMeasurements for this reporting period. Exhibit 3 provides a table titled Section 4 Active MonitoringWells, Analytical Results and Water Level Measurements for a cumulative period since 2005.

Section 15C:Exhibit 4 provides a copy of the signed laboratory analyses for this reporting period.

Section 15D:Exhibit 1 presents the time versus concentration plots and hydrographs for MW-22, MW-23, and MW-32 since approximately 1995.

Section 15E:Because of insufficient alluvial water in the Section 4 pond area and since many of the monitoringwells are dry, the development of a potentiometric map for the alluvium was not undertaken.
