1. SUMMARY

1.1. Introduction

The 2011 mine plan was completed in June 2010. The following initial assumptions of the 2011

mine plan have changed dramatically during this several month period of mine development:

1) End of 2010 mine status projection has changed mainly due to geotechnical and

production scheduling issues.

2) Final date of Main-pit completion reset to December 2011 from 2012.

3) Equipment availability, such as 12 haul trucks will be available until September of 2011.

This 2011 Mine Plan Addendum is a collection of revised monthly 2011 mine production plans,

equipment forecast, Aqqaluk dewatering plan and other major changes.

1.2. Mine Production

The production target forecast has been reset to 13,341 kt of total mine production from the

Main Pit and the Aqqaluk Pit (Table 1-1). The 3,487 kt of ore at XX.X% Zn and X.X% Pb is from

the Main Pit and Aqqaluk Pit throughout 2011. Within the total 9,854 kt of waste scheduled,

8,368 kt is from the Aqqaluk Pit.

1.3. Equipment Fleets

For the first three quarters of 2011, the equipment required to achieve the 2011 plan will remain

unchanged from current fleet size (Table 1-2). Red Dog purchased three 777F Haul Trucks, one

993K Loader, and one DML Drill in 2010 as replacement equipment but due to the increased

demands from Aqqaluk stripping, the equipment intended to be replaced was rescheduled as a


result of the permit delay. A D10 dozer was also leased to support the Aqqaluk development.

Once Aqqaluk stripping is completed in 3rd quarter of 2011, three trucks, one drill, one loader,

and one dozer will be decommissioned.

2011 Aqqaluk Dewatering Summary

Beginning December 2010 a new haul road (green in Figure 4-1) will be constructed on the west

end of the Aqqaluk deposit. The road will be finished in January 2011. The construction of the

haul road will intersect the existing dewatering ditch in Aqqaluk (teal in Figure 4-1). The existing

ditch and new haul road will intersect at the 1045 elevation at a settling pond (red in Figure 4-1).

A new dewatering ditch (pink in Figure 4-1) will be excavated on the original ground side of the

haul road and flow to another settling pond at the 1010 elevation. From the settling pond at

1010 a 36” culvert (orange in Figure 4-1) will be needed to move the flow of water to the mine

side of the haul road. After the road crossing, water will continue to flow to the 950 elevation

into a third settling pond. The settling pond on 950 will also hold water from a temporary

dewatering ditch dug into the 950 bench (purple in Figure 4-1). The 950 ditch will be extended

as mining allows and can be moved where needed to collect water flowing through the highwall.

The 950 collection ditch may require blasting, so future mine sequencing will have to be

considered before it is extended each month.

A second culvert from the 950 settling pond will be needed to intersect the existing dewatering

ditch on the Aqqaluk haul road.

Below the new haul road a ditch will have to be dug (blue in Figure 4-1) to collect any water

running off the original ground side of the haul road. The ditch will require blasting and

excavator work to intersect the Aqqaluk haul road at the 915 elevation.

Further down the Aqqaluk haul road, at approximately the 870 elevation, a settling pond will

need to be dug out. The pond will be lined with a connex container. Water will flow from the

870 settling pond to the Red Dog Creek pump back station.

The ditch to the north of Aqqaluk (pink in Figure 4-2) needs to be completed to design, 40 feet

from the mine side of the silt fence, before spring break up.

The end of year dewatering layout for the west and north end of Aqqaluk for 2011 is shown in

Figure 4-2.

Dewatering needs on the south end of Aqqaluk will remain mostly unchanged. There is a sump

and electric pump in place (yellow in Figure 4-3). There is also a sump (green in Figure 4-3) to

collect runoff from the Aqqaluk haul road at the 880 elevation. A portable pump can be moved

here if required.

Natural water channels (brown in Figure 4-3) will have to be expanded to accommodate the

increased water flow as Aqqaluk haul road is removed. A road crossing culvert will also be

needed to allow access to Shelly Creek drainage area.

A summary of 2011 Aqqaluk dewatering is shown below in Table 4-1 with the approximate

beginning month for each project. Water issues should not arise until later in the year, as the

temperature begins to rise and breakup occurs.
