Drilling expands Pit 3 mineralization and intersects 119 feet of 2.1% cu and 23 g/t ag in the Oriole Deposit
Copper Mountain Mining Corporation ("CMMC" or the "Company") is pleased to provide results from its on-going exploration program, where results continue to add to, and upgrade resources. Successful drill results have encouraged the Company to expand the 2008 drill program to 60,000 meters (197,000 feet). The objectives of the drilling program have been to increase the size and grade of the overall resource; particularly in areas adjacent to and below the designed Super-pit area, and to discover new zones of mineralization. The discovery of new areas of mineralization has been greatly aided by the Titan 24 Geophysical Survey which outlined substantial areas of high-chargeability both near surface and at depth. Results of the drill program will be incorporated into a new resource estimate planned for completion by year end.
<<
Recent drilling has been carried out in the Pit 1, Pit 3 and Oriole areas
as well as some drill-holes for engineering purposes. Key results being
reported in this release are from the Pit 3 and Oriole areas and include:
- In the Pit 3 area, drill-hole CM08P3-33 collared 200 feet North-east
of the existing Pit 3 rim, intersected mineralization over 214 feet
(65.2m) grading 0.84% Cu, 0.27 g/t Au, and 3.70 g/t Ag (0.97% Cu
Equiv.) that is within the planned Super Pit and should improve mine
economics.
- In the Oriole area, drill-hole CM08OL-17 is the most significant
intersection in this batch being released today, which intersected
119 feet (36.3m) grading 2.10% Cu, 0.10 g/t Au, and 22.7 g/t Ag
(2.31% Cu Equiv.) approximately 1,100 feet south-east of the most
southern edge of Pit 3. Definition of resources in the Oriole area
could result in a southerly expansion of the Super Pit.
>>
Highlights of the results for the new drill holes in Pit 3 and Oriole are listed in the table below and drill-hole locations are shown on the attached map. Complete results can be found on the company's website.
Pit 3 Area: Twenty-eight additional drill holes have been completed in the Pit 3 area: thirteen holes were drilled peripheral to Pit 3 to test for outward extensions and/or new mineralized zones within the Pit walls; and fourteen holes were drilled from the bottom of the historical pit to test for depth extensions to the mineralization. Drilling from the pit bottom was to follow-up on previous significant intersections (322 feet grading 1.31% Cu) that were below, both the historical underground mine workings, and the bottom of the designed Super Pit, as reported in the recently completed feasibility study.
Drilling results in the eastern wall of Pit 3 have been positive with most drill holes intersecting some mineralization and many with significant intersections such as CM08P3-13 (90 feet of 0.58% CuEq near surface and 205 feet grading 0.58% CuEq. near the bottom of the Super Pit), CM08P3-22 (236 feet of 0.71% CuEq at mid-depth of the Super Pit) and CM08P3-28 (232 feet grading 1.00% Cu Eq. in the lower wall and 230 feet at 0.46% CuEq towards the pit bottom). Drill results in the Pit wall will help to up-grade some inferred blocks to the Indicated category, thereby improving Pit economics as well as likely adding to the overall resource base.
Drilling from the bottom of Pit 3 is being carried out to extend the high-grade mineralization to depth and delineate resources below the Feasibility Super Pit. Drill-hole CM08P3-16 was drilled from the bottom of Pit 3 approximately 500 feet to the south of the high grade zones encountered in CM08P3-08, and encountered the corresponding zones of mineralization, including an 80 foot intersection grading 1.16% Cu, (1.19% Cu Equiv.) Drill hole CM08P3-40 was drilled from the pit bottom to the east in order to test a large geophysical anomaly that extends below the Pit in an easterly direction. The upper part of this drill hole encountered strong mineralization (280 feet grading 0.76% Cu, 0.12 g/t Au, and 2.12 g/t Ag (0.82% Cu Equiv.) but deeper mineralization consists of scattered moderate to low grade mineralized intersections.
Oriole Area: Five additional holes have been completed in the Oriole area which is located, along strike and immediately south of Pit 3. Development of resources in this area may allow for a significant southward expansion of the Super Pit. The Oriole area is characterized by narrow high-grade mineralized zones located between late, barren dykes. Mineralization extends over an area of about 700 feet in the east-west direction and for 1,000 feet in the north-south direction. Drill-hole CM08OL-17, in the south-central part of the Oriole deposit, intersected a 119 foot interval grading 2.1% Cu and 22.7g/t Ag (2.31% Cu Equiv.).
The mineralized system at Copper Mountain is classified as a bulk-tonnage, alkalic porphyry copper deposit that is hosted within Nicola Group volcanic rocks. Mineralization is structurally controlled and focused at multi-directional vein intersections and within vein stockwork systems. Drill holes are usually drilled at angles of -45 or -55 degrees to provide the best indication of the lateral extents of vertically oriented mineralization.
Quality Assurance
The company employs a system of quality control for drill results which includes the use of blanks, certified reference material (standards) and check assaying. Core is logged on site and split with a diamond saw. Samples are shipped to Pioneer Laboratories for geochemical analysis of copper with all values of greater than 1,000 ppm copper being re-analysed by assay methods for copper, gold and silver. The drilling program is being supervised by Peter Holbek, M.Sc., P.Geo., a qualified person as defined by National Policy Instrument 43-101.
About Copper Mountain Mining Corp.:
CMMC is a BC resource company that owns 100% of the Copper Mountain Project located 15 km south of the town of Princeton in southern British Columbia. The Company recently completed an independent feasibility study that confirmed the viability of restarting this past open pit copper and precious metal producer. Development is based on the construction of a new 35,000 tonne per day concentrator to produce approximately 100 million pounds of copper per year in a copper concentrate with gold and silver credits by the end of 2010. The mine resource includes; a Measured and Indicated Mineral Resource of 186 million tons averaging 0.411% Cu containing 1.5 billion lbs copper and an Inferred Resource of 92 million tons averaging 0.344% Cu containing 0.6 billion lbs copper (see press release July 28, 2008). A copy of the Independent 43-101 Technical Report pertaining to the interim resource estimate and a video presentation on the Copper Mountain Project may be found on the company's website. Copper Mountain Mining Corporation's shares currently trade on the TSX Exchange under the symbol CUM and additional information is available on the Company's web site at www.CuMtn.com.
