VANCOUVER, Dec. 21, 2012 /PRNewswire/ - Copper Mountain Mining Corporation
(TSX: CUM) (the "Company" or "Copper Mountain")  announces production guidance
for the 2013 year from the Copper Mountain mine located in southern British
Columbia.

Copper Mountain  is projecting  2013 production  of approximately  80  million 
pounds of copper, 35,000 ounces of gold, and 315,000 ounces of silver. -  Site 
cash cost are estimated to be (incl. mining, milling, maintenance, admin,  and 
engineering) of $1.25  - $1.30 per  pound of copper  produced net of  precious 
metal credits. (Calculated based on $ 3.40 /lb Cu, $1,500/oz Au and  $28.50/oz 
Ag). Total cash costs (incl. site costs, smelting & refining, transportation,
interest and taxes) are  estimated to be  between $1.80 -  $2.00 per pound  of 
copper produced net of precious metal credits.

The mining rate is projected to continue at a rate of about 175,000 tonnes per
day to provide 35,000 tonnes per day of mill feed. The forecast production  is 
based on  a  head  grade  of approximately  0.35  percent  copper.  Mine  site 
operating costs are estimated to  total approximately $13.65 per tonne  milled 
with mining costs projected at $1.48 per tonne mined.

From an operational point of view, the mine plans to continue to mine in  both 
the Pit 2 and  Pit 3 areas.  Approximately 16 million  tonnes of lower  grade 
material will be stockpiled for processing towards the end of the mine life.

The Company's goal  for 2013  is to continue  to optimize  performance of  the 
Copper Mountain Mine, to maximize our copper production.

Management plans  to continue  the exploration  drilling for  2013 which  will 
build from the 2012  exploration program. The  2012 exploration drilling  has 
been focused along the western and northern  edges of Pit 2, partly to  expand 
the pit limits,  test mineralization at  depth and to  infill gaps within  the 
resource model. Exploration staff are continuing  to cut the drill core  from 
the 2012 exploration  program and management  expects to be  in a position  to 
comment on the second half 2012 exploration results during Q1 of 2013.  Plans 
for the  drill 2013  program will  be  finalized after  the 2012  results  are 
evaluated.
