Copper Mountain commissioned the secondary crusher in August 2014, on budget and on schedule, to improve throughput and maximize production
The new secondary crusher processed its first ore on August 3rd 2014.

The Lower Main frame is the largest component piece of the secondary crusher and weighs a little over 100 tonnes. Cranes were used to load the Lower Main Frame from the rail car to the specialized transportation truck, which then transported the piece to the mine site over a 5 day period at night to avoid traffic on the roads. - March 2014
Due to the weight and size of the component pieces of the secondary crusher, special permits and various specialized transportation trucks were required to safely move the secondary crusher parts from Kamloops, BC to the Copper Mountain Mine site. - February 2014

By successfully combining pits #1, #2, and #3 into one merged "Super Pit", will allow for greater access to the mineralized areas. The resource is 5 billion lbs of copper with gold and silver as secondary credits.
The 240 ton-capacity-haulage trucks require 3 passes from the hydraulic shovel, to be filled to capacity, before the ore is transported to the primary crusher.
Mining activities at Copper Mountain started with a pushback on the western wall of Pit 3 but eventually operations will extend into pit 1. As pit 1 is expanded, it will merge with pit 2 until all three pits are converged into one super pit

The mobile mining fleet consists of 2 PC 8000 hydraulic shovels (Komatsu), 13 830 E 240 ton haul trucks (Komatsu) , 1 WA 1200 Loader (Komatsu) , 2 D375 Dozers, 1 16M Grader, 2 AC271 rotary drills and 1 AC351 Rotary drill.
Pre-production mining activities commences on the Copper Mountain Mine in November 2010 upon the arrival of the mine's main loading unit, the Komatsu PC 8000 hydraulic shovel.

In November 2010, Komatsu hosted a celebration at the mine to mark their commissioning of the 75th PC8000 shovel to be manufactured worldwide.
A 240 ton haulage truck dumps ore into the primary crusher that crushes 60 inch rocks into 6 inch pieces.
10 story high primary crusher and the approximately one-kilometer long ore conveyor.
The coarse ore stock pile contains 4 days worth of mill feed.
The concentrator facilities are operated from a state-of-the art control room.
The modern and efficient process plant is a facility where the ore is processed from the mine to separate out key components and prepare them for export.
Panoramic view of the interior of the process plant. Real life size of the concentrator building is as high as a ten story building and as long as 1.5 football fields.
The discharge from the primary crusher is the feed to the SAG mill. The SAG mill breaks the ore down into smaller pieces with friction and impact with 5 inch diameter steel balls. It is powered with electric motors.
Major milling equipment had an estimated delivery time of 30 months so the company had to order the pieces prior to completion of the feasibility study, to stay on track with their target schedule.
Discharge from the 34 foot diameter SAG mill is less than 2 inches in size.

The ground rock and water with no copper mineralization flows to the tailings management facility where the water is re-used in the mill. Approximately 76% of the total water requirements for the mill process is recycled from the tailings management facility.
The separation of the barren rock from the copper minerals is completed in the rougher flotation cells.
A reagent is added inside the flotation cells to coat the copper particles.
Copper mineral particles stick to the bubbles and float to the top.
After passing the floatation process, the cleaner flotation concentrate, is sent to the thickener to settle to a consistency of approximately 50% solids. This thickened concentrate is then pumped to the filter press panels where the moisture content is reduced to approximately 9% moisture.
Copper Concentrate, the final product at the mine, is filtered to 8% moisture and contains copper, gold and silver. Here it is being sampled by a laboratory technician before it is loaded into the concentrate trucks to be transported to the Vancouver Wharf for ocean shipment to Japan.
Specially built 50- tonne nine-axle B-train truck units.
Trucks unload on the newly built truck tipper. Then the concentrate is stored until and ready for shipment to Japan.
