Endeavour Acquires San Pedro Properties In Guanacevi Silver District, Durango, Mexico

    VANCOUVER, Dec. 12 /CNW/ - Endeavour Silver Corp. (EDR: TSX, EXK: AMEX,
EJD: DBFrankfurt) announces the acquisition of an option to purchase the
San Pedro properties, located about 6 km northwest of Endeavour's operating
Porvenir Mine, in the Guanacevi silver district, Durango State, Mexico.
    The 15 San Pedro properties (330 hectares) cover the heart of the
historic San Pedro sub-district north of Guanacevi, and include the famous
El Soto, Nuevo Australia, Noche Buena and Buena Fe silver mines. They boost
Endeavour's land holdings in Guanacevi by 53% to 957 hectares, and give the
Company a major new prospective area to explore for high grade silver
    Like the Guanacevi district, the San Pedro sub-district was originally
founded in the late 1500's for its famously high grade silver ores. However,
unlike Guanacevi, the silver mineralization at San Pedro is found in manto
orebodies where high angle vein structures crosscut the shallow dipping
contact of Cretaceous conglomerates with overlying Tertiary andesites. For
complete details on the Guanacevi Mines Project click <a href="http://www.edrsilver.com/s/Guanacevi.asp">here</a>.
    By the early 1900's, the El Soto and Nueva Australia mines were developed
and producing from 9 levels and 12 shafts down to a maximum depth of 167 m. In
1921, the Mexico Consolidated Mining and Smelting Co. Ltd. reported that the
rich silver manto ores at El Soto-Nueva Australia typically graded
1000-2000 gpt silver, 1-30 gpt gold, and 1-10% lead-zinc, with direct shipping
smelter ores assaying up to 20,000 gpt silver.
    East and down-dip of El Soto-Nueva Australia lie the Noche Buena and
Buena Fe Mines, which recorded minor historic production, but similar high
grade ores. In this area, the hangingwall andesites are strongly altered to
clay and adularia, mineralized with pyrite and anomalous in silver, suggesting
buried mineralization at depth. Dr. Larry Buchanan, author of some of the most
definitive technical papers on epithermal vein systems, visited the San Pedro
sub-district in 1993 and wrote, "The Buena Fe area presents a very attractive
exploration target for major tonnages of manto ore. The size and intensity of
the geochemical anomalies and of the wallrock alteration suggest that the
Buena Fe area may host as much mineralization as has been mined in the past
from San Pedro."
    He estimated past production from El Soto-Nueva Australia and other mines
in San Pedro at around 450,000 tonnes grading 1500 gpt silver and 1.5 gpt
gold, or 25 million oz silver-equivalent. Endeavour believes this historic
estimate to be reasonably accurate based on the known extent of underground
mine workings at San Pedro. However, the Company has not independently
verified this historic estimate and so it should not be relied upon.
    Endeavour can acquire a 100% interest in the San Pedro properties, by
paying 120,000 common shares and issuing 60,000 warrants to purchase
60,000 shares at US$4.69 within a 1 year period, upon receipt of regulatory
approval and a further 570,776 shares within a 24 month period. The vendor
will retain a 1% net smelter royalty on mineral production.
    In addition, the Company will provide the Vendor with up to US$400 per
meter to advance the Buena Fe adit during the 24 month option period. Any ores
produced from this tunnel will be used to repay Endeavour's investment, after
which the net profits will be shared equally (50/50) with the Vendor.
    In this way, Endeavour anticipates generating positive cash flow to help
pay for the exploration programs on the properties. A Phase 1 program of
IP-Resistivity geophysics and geological mapping is expected to commence in
Q1, 2008 in order to help target the prospective vein-manto intersections for
    Bradford Cooke, Chairman and CEO, commented, "The San Pedro properties
not only substantially expand Endeavour's prospective land-holdings at its
Guanacevi Mines Project, they also provide the Company with most of the
San Pedro sub-district to explore for new high grade silver manto deposits. We
are thrilled by the opportunities for new silver discoveries at San Pedro."
