2012 Phase 1 Exploration Drill Results
Vancouver, B.C., September 5th, 2012 – Copper Mountain Mining Corporation (“CMMC” or the

“Company”) announces assay results from the first phase of the 2012 exploration program.

The 2012 exploration program, which consists of two phases, commenced in late May and through to the end of July, a total of 9,800m of diamond drilling has been completed in 50 holes. Phase 1 diamond drilling targeted three areas: the southern end of Pit 3, the northern side of Pit 2 and the western part of the Alabama trend. Phase 2 of the program will be completed by the end of the year and will consist of approximately 10,000 meters of diamond drilling.

Phase 1 drilling on the south end of Pit 3 was completed to obtain additional geotechnical data, and verify the extent of historical mining in order to assist with pit planning and deeper drilling. Four holes were drilled along two sections from the western side of the deposit. Results are listed in the table below. The first hole, drilled at -60o to a depth near the bottom of the planned Super pit, intersected the intrusive-volcanic contact, and the mineralization that occurs there, on target, but was lost after a short distance due to intersecting underground workings. The second drill hole at -47o was completed to target depth and intersected 80m of mineralization with a 0.4% average copper grade, approximately 100m above the 12P3-01 intersection. Drill holes P3-03 and 04 were drilled at -47o and -60o, respectively, on a section 120m further to the south than the P3-01/02 section. Drill hole 12P3-03 is the shallower hole and intersected 42m of mineralization grading 0.82% copper before entering a dyke-filled fault zone running sub-parallel to the drilling direction. Drill hole 12P3-04, the deeper hole on this section, intersected 38m grading 2.14% copper. ...
