Columbus Silver Drilling Update, Mogollon Silver-Gold Project, New Mexico

Marketwired
Columbus Silver Corporation (TSX VENTURE: CSC) ("Columbus Silver"
or the "Company") is pleased to provide the following drilling
progress report from its 100% controlled Mogollon silver-gold
project, Catron County, New Mexico. The Mogollon Project covers
most of an extensive, silver-gold bearing epithermal vein field
totaling more than 45 miles (72 km) of strike length of which only
3 miles (4.8 km) have been developed.
The current drilling campaign consists of approximately
7,500-8,000 ft (2,286-2,438 m) in up to 14 diamond core holes and
is designed to test the east-west trending Anna E and
Independence-Ida May veins.
There are two sets of veins at Mogollon which account for the
majority of historical production, a north-south set represented by
the Queen vein, hosting the former Consolidated Mine, and an
east-west set represented by the Little Fanney and Last Chance
veins, hosting former mines by the same name. Historical recorded
production from these veins between 1905 and 1942 is reported to
total 15,700,000 ounces silver and 327,000 ounces gold from
approximately 1.7 million tons (1.5 million tonnes) of ore
averaging 9 opt (308 g/t) silver and 0.18 opt (6.17 g/t) gold.
The only drilling known to be carried-out in the Mogollon
district occurred between 1981 and 1989 (see press release of May
26, 2009) and was successful in outlining a partially delineated
silver-gold deposit at the former Consolidated Mine in the Queen
vein containing an historical resource of approximately 845,000
tons (767,000 tonnes) averaging 9.35 opt (320 g/t) silver and 0.15
opt (5.1 g/t) gold.
There are dozens of mineralized and potentially mineralized
veins at Mogollon that have never been drill tested providing
potential for considerable resource expansion. The principal aim of
the current drilling program is to test new veins, the Anna E and
Independence-Ida May veins which have near-surface characteristics
similar to the past producing Little Fanney and Last Chance veins
but have only been explored by shallow workings or have had either
limited or no drilling.
Based on the historical production data from the former
Consolidated, Little Fanney and Last Chance mines and on the
drilling programs completed at Consolidated in the 1980's, the
high-grade silver and gold mineralization in the Mogollon District
is present in broad zones of quartz and calcite veins and
silicified breccias cut by stockwork quartz veinlets along faults.
Stoping widths in the past producing mines range from 5 to 25 ft,
averaging about 9 to 11 ft. Historical production on the Last
Chance and Fanney veins occurred mostly below an elevation of
approximately 6,950 ft. These two productive veins did not extend
to the surface, being marked only by cracks along faults with
occasional barren quartz veins up to a few inches wide. The current
drilling program was therefore designed to penetrate the target
veins below the 6,900 ft elevation with angle holes drilled from
surface from 500 to 800 ft in depth.
In the current program, three holes were drilled at the Anna E
vein and attempted to extend the significant mineralization drilled
in 1984 (best assay 5 ft of 0.415 opt (14.2 g/t) gold and 15.49 opt
(530 g/t) silver) for an additional 200 ft down the dip of the
structure. These holes were not successful. Fifty feet wide zones
of quartz, calcite, and fluorite veining were cut below the
previous drill holes but initial assays show only anomalous gold
and silver (best assay 4.5 ft of 0.019 opt (0.66 g/t) gold and
trace values of silver). The Anna E vein remains open on strike,
and the best values seem to be confined to a zone from near the
surface down to about 250 ft of depth.
So far, four angle core holes have been completed in the area of
the Independence-Ida May veins. All holes have been logged
geologically, the mineralized parts of the core sawn in half, and
submitted for assay to Skyline Laboratories in Tucson. No assay
results have been received on these holes. The first three holes
were spread along 2,400 ft of the strike of the Ida May vein and
placed to cut the vein at about 6,850 ft of elevation. These three
holes cut wide zones of quartz veining and stockworks in silicified
breccia (up to 75 ft wide) in the Ida May structural zone, but
individual quartz veins within this broad zone are only about 2-2.5
ft in width. The fourth hole cut the Ida May structure at about
6,700 ft in elevation, again cutting a broad zone of veining and
silicification, but with considerably more quartz overall and one
individual vein zone that reached 9 ft in width. The next two holes
are planned to test the Ida May vein at this elevation, as the
mineralization seems to be strengthening with depth based on visual
observations.
Columbus Silver plans to release full results when the first 9
holes of the program are completed and assayed.
