New portable crusher

Contract Pre-crushing

In the short & immediate term, the following has been implemented to increase throughput:

a) High Powder Factor blasting of ore in Pit 3 & Pit 2 has been included as normal operating process

b) A contractor continues to supply up to 5,000 TPD of crushed ore to blend with mill feed

c) An Additional portable crusher has been acquired and installed at coarse ore stockpile to provide increased -2’’ SAG mill feed at a rate of 7,500 TPD (more direct effect)

TSX:CUM

Current Considerations SAG Pre-crush Production Improvement

Tightened up the gyratory crusher

to 5 ½ “

Increase powder factor in pit blasting to

improve fragmentation

New policy – ore blending is

restricted to ~40% pit 3 max

Newly installed camera monitors ore size on SAG feed conveyor

• Ball mills have proven to have extra capacity available to process tonnage in the 40,000tpd range.

• Mill throughput has been limited by the SAG mill capacity with the crushed ore from the primary crusher but operates well at the 40,000tpd range with finer SAG mill feed.

• Improvements in operating time since implementation of high energy blasting and contract pre crushing with the finer feed to the SAG mill.

• Osisko’s Malartic mine & Newmont’s Pheonix mine experienced a 25% - 30% increase in tonnage after they installed a secondary crushing.

TSX:CUM

18

Install a Secondary Crusher to pre-crush 100% of SAG mill feed to minus 1”

Capital cost projected at $35 - $40 million over 12 month construction period with minimal disruption to operation

Simple payback period of less than 1 year

Tonnage capacity increase to 40,000tpd range

Based on tests & engineering studies to date, installation of SAG pre-crusher is necessary to ensure consistency of SAG mill feed size over the long term to maximize copper production

Copper Mountain Trend

Alabama Trend

23 TSX:CUM

18,400m of core drilling and 3,300m of percussion drilling The program was successful in four ways: 1. Drilling extended Pit 2 mineralization to the north beyond

the Superpit limits and mineralization remains open. 2. Drilling under Pit 2 extended the zone of high grade

mineralization that occurs below the Superpit to the west. 3. High grade mineralization was intersected immediately

below the Superpit limits in the Pit 3 area. 4. Drilling in the Alabama zone resulted in long, continuous

intersections of low to moderate grade mineralization starting at the bedrock surface.

“Exploration was successful in extending known mineralization both laterally and to depth, beyond the limits of the existing resource” ~ Peter Holbek, VP of Exploration
