Interesting facts that were backed by a 43-101 document in 2008.

*********************************************************

 • 100,000 TONNES PER DAY OPEN PIT MINE WITH STANDARD FLOTATION RECOVERY

• METALLURGICAL TEST WORK YIELDED: 88% COPPER, 82% GOLD, 72% SILVER AND 71%

MOLYBDENUM RECOVERY

• ANNUAL METAL PRODUCTION: 211 MILLION LBS (110,000 TONNES) COPPER, 199 THOUSAND

OZS GOLD, 1.4 MILLION OZS SILVER AND 11.3 MILLION LBS (5,600 TONNES) MOLYBDENUM

 • EXPANSION CAPACITY: DEMONSTRATED ABILITY TO INCREASE MINING TO IMPROVE PROJECT

ECONOMICS. INDICATED MINERAL RESOURCE COULD BE CONVERTED TO MINABLE RESERVES

TO SUBSTANTIALLY EXTEND MINE LIFE

3.14 Economic Analysis A financial model was created utilizing the mine production schedule, the associated metal grades based on the geological resource estimate, metal recoveries from the ongoing metallurgical test program, capital and operating costs as set out herein and base case metal prices, trailing three year average from August 29, 2008, of copper $3.12/lb, molybdenum $33.00/lb, gold $692.85/oz and silver $13.09/oz.

They had a 100 000 tpd design and now going with a 133 000 tpd design.

Gold & Silver LT consensus prices are much higher today.  Yet, with their numbers, they still managed to get a NPV (8%) of 2.76B US with a cost to produce a pound of copper (net of other metal credits) at -$0.32 US.

A lot of room for improvement vs. the 2013 extremely conservative FS!

IMO.
