Copper Mesa commences drilling on Zonia Mine copper project in Arizona

    VANCOUVER, Aug. 18 /CNW/ - Copper Mesa Mining Corporation ("Copper Mesa")
or (the "Company") (TSX: CUX) is pleased to announce that, through its
wholly-owned subsidiary, Redstone Resources Corporation, it has acquired the
necessary permits and initiated drilling at its Zonia Mine copper project in
Yavapai County, Arizona.
    Two separate drill programs, both designed in consultation with the
Company's chief engineering advisor on the project, Tetra Tech Inc.
(NASDAQ:  TTEK), have commenced.
    The first drill program, which began on August 4 of this year, consists
of sonic drilling of 17 holes (approximately 1,800 feet) to produce material
both for subsequent assaying as well as for the testing of geotechnical
characteristics of areas being considered as sites for construction of
facilities for the proposed mining operation.
    The second drill program, comprised of diamond drilling of 15 holes
(approximately 3,000 feet), commenced last week. The primary purpose of this
program is to twin numerous existing holes for confirmation of historical
tonnage and grades through check assays to facilitate the re-estimation and
reclassification of the copper resource to be compliant with National
Instrument 43-101 (NI 43-101), Standards of Disclosure for Mineral Projects,
by the end of October 2008.
    "With the drill programs underway, we will begin preparation of a
pre-feasibility study to be completed by the end of 2008 and have all permit
applications submitted for construction of an open pit mine and a solvent
extraction/electrowinning (SXEW) processing complex, averaging 20 million
pounds of copper per year, by the end of the second quarter of 2009," said
Gary Davis, President and CEO of Copper Mesa Mining Corp.
    The Zonia Mine copper project is located on 3,222 acres of patented and
unpatented land. In October, 2006, Scott Wilson Roscoe Postle Associates Inc.
prepared a NI 43-101 compliant inferred resource estimate of 63 million tons
of material at a copper grade of 0.37% (using a 0.25% cut-off grade). Based on
historical data, almost all known materialization is oxide and amenable to
heap leaching and SXEW processing technology for the recovery of copper. In
the 1970s, the then-owner of the Zonia Mine property produced over 30 million
pounds of copper from the site using heap leaching technology.
