United Silver Corp. ("United Silver Corp.", the "Company", or
"USC") (TSX VENTURE:USC)(OTCQX:USCZF)(FRANKFURT:UM8) is pleased to
announce that the Board of Directors has approved a phased,
property-wide, USD$23 million, four-year plan (the "Plan") to
further explore and develop the Crescent Silver Mine resource. The
objectives of the Plan are to further explore the existing silver
resource, develop the existing resource, and explore for additional
resources at the Company's 80 percent-owned Crescent Silver Mine.
The Crescent Mine is located on a large, 365 hectare (902 acre)
property in the heart of northern Idaho's Silver Belt, in the Coeur
d'Alene silver-lead-zinc mining district. The Crescent Mine is
situated between the world-class, previously-mined Sunshine silver
mine and the Bunker Hill silver-lead-zinc mine, with previous
district-wide production estimated to be over 1 billion ounces of
silver, making it the second largest silver district in the world
(for details of the Crescent property, the Idaho silver belt, and
figures which assist in visualizing the details of this press
release please refer to our website at
www.unitedsilvercorp.com).
Approximately 25 million ounces of silver at an average grade of
27.3 opt (SRK Consulting 43-101, March 1, 2010) were historically
mined from the Crescent Mine, and known mineralization has been
identified from near surface to approximately 5,000 feet depth
below surface by the Bunker Hill Mining Company, prior owners of
the Crescent Mine. We consider this historical information to be
reliable.
Silver and base-metals-bearing vein deposits at Sunshine and
Bunker Hill, located immediately to the east and west of, and
adjoining, the past-producing Crescent Mine, were world-class
deposits of silver. The Crescent Mine, which was a much smaller
producer than the other two deposits, has never undergone a
detailed and aggressive exploration program, despite the fact that
the ore-bearing vein systems strike across the large, 365 hectare
property, and are known to host high-grade silver-bearing vein
deposits. The planned program at the Crescent is designed to
aggressively follow up on known mineralization, and to produce
silver-bearing concentrates from known mineralized bodies to fund
the exploration of the depth and lateral extensions of the known
mineralization.
Very significant surface drilling and underground exploration in
the form of a spiral ramp and drifting within the known
mineralization closest to surface has already been completed. The
objective of the current Plan is to restart, aggressively, this
partially-completed exploration/development work which began in
2007. Highly-encouraging results from this earlier work form the
basis for this aggressive exploration/development plan, which has
the goal of unlocking what management believes is a very high
potential for the delineation of a significant silver resource.
The initial phase of the Plan will be funded by a
recently-announced USD$6.3 million convertible debenture from Hale
Capital Partners (see press release dated February 1, 2012) and by
a contribution from 20% joint venture partner Gold Finder
Explorations Ltd. ("Gold Finder") (TSX-V: GFN) as its share of the
program. Ongoing costs of the Company and Gold Finder for the
exploration/development plan are projected to be funded by cash
flow generated from the milling and refining of silver
mineralization mined from known mineralized bodies defined by
previous, detailed surface drilling and underground exploration
programs.
Previous Work
Subsequent to mining in the early part of the last Century,
exploration began again at the Crescent mine in 2007 with drilling
carried out by Gold Finder. A total of 31,460 meters were
completed, primarily from surface, on the South Vein, resulting in
a 43-101 compliant resource estimate of 324,000 tons grading 18.7
ounces per ton (opt) of Indicated and 211,000 tons of Inferred
mineralization grading 19.5 opt. This drilling was carried out over
an area which accounts for less than 5 percent of the prospective
areas of the property. Highlights of the Gold Finder drilling
include:
---------------------------------------------
South Vein Intercepts Silver grade
---------------------------------------------
SNS403 10.0 feet @ 56.0 opt
---------------------------------------------
SNS305a 6.8 feet @ 42.1 opt
---------------------------------------------
SNS310 5.6 feet @ 25.3 opt
---------------------------------------------
SNS1006 6.3 feet @ 21.1 opt
---------------------------------------------
SNS307 5.1 feet @ 21.6 opt
---------------------------------------------
SNS1002 7.0 feet @ 17.6 opt
---------------------------------------------
H304 7.8 feet @ 11.0 opt
---------------------------------------------
Alhambra Vein Intercepts
---------------------------------------------
SNS502 6.2 feet @ 41.2 opt
---------------------------------------------
SNS604 6.2 feet @ 16.4 opt
---------------------------------------------
SNS1107 4.9 feet @ 20.6 opt
---------------------------------------------
While the above drilling forms the basis of the current resource
calculation (SRK 43-101, March 1, 2010), it was recognized that the
silver-hosting veins had a strike continuity across the entire
property towards the west and into the adjoining Bunker Hill mine
property. In 2011, 11,275 feet of surface drilling in nine holes
was completed up to 1500 feet west of the existing resource. The
results of the first four Alhambra-targeted holes (see press
release dated May 16, 2011) intersected 2.2 feet grading 4.8 opt
silver, proving westward continuity of the mineralized system. All
five holes drilled into the South Vein structure (, up to 1500 feet
west of the known resource) encountered siderite-quartz-pyrite
veins, demonstrating continuity of this structure as well as
opening a large area for exploration. The highest grade intercept
of these five holes returned 2.9 feet grading 4.58 opt silver.
Underground Exploration
The existing Hooper Level tunnel (2725 feet elevation, see
website for 3-dimensional view of underground workings) provides an
excellent platform to test the down-rake extension of the South
Vein resource. The South Vein resource, meanwhile, has been
estimated to an elevation of 2940 feet. Therefore, in 2011, a
program of 12,000 feet of drilling to test the down-rake extension
of the South Vein was proposed, of which only two holes totaling
1,449 feet of drilling were completed due to funding
limitations.
These two holes gave highly-encouraging results, indicating that
the South Vein resource is open to depth and that further drilling
is definitely warranted. The two holes intersected silver
mineralization as follows:
----------------------------------------------------------------------------
From To Feet True Silver
DDH (feet) (feet) Recovered Width (Feet) (opt)
----------------------------------------------------------------------------
H-6 720.20 724.0 3.40 3.11 25.6
----------------------------------------------------------------------------
Includes 721.40 722.40 0.90 0.82 96.40
----------------------------------------------------------------------------
H-7 727.00 729.70 2.70 2.21 3.60
----------------------------------------------------------------------------
Includes 727.00 727.65 0.65 0.50 8.80
----------------------------------------------------------------------------
A core loss of 6.5 feet between 718 and 728 feet in H-7 may have
been from a mineralized, faulted zone within the South Vein. The
H-6 intersection is at an elevation of 130 feet below and is 300
feet west of the lowest point of the limit of the calculated South
Vein resource, and remains open to depth and along strike,
indicating good potential for quickly expanding the known resource
by further drilling.
Underground Test Drifting
A decline to facilitate lateral drifting for underground
exploration and eventual production activities, called the Countess
decline, was collared by the Company in August, 2010 from a surface
portal at 4300 foot elevation and progressed for 2400 feet to a
point where it intersected the South Vein resource (as defined by
SRK in their 43-101) at the 3945 foot elevation.
Test drifting along the South Vein structure at the 3945 foot
elevation began in March 2011 and, as of January 2012, a continuous
755 feet of strike length along the drift within the South Vein
body yielded 10.4 opt silver over an average width of 9.2 feet. The
most significant intervals intercepted by this drift sampling
include:
------------------------------------------------------------
Strike Length Average Silver Grade Average Width
(feet) (opt) (feet)
------------------------------------------------------------
246 14.0 7.3
------------------------------------------------------------
210 15.6 8.3
------------------------------------------------------------
88 15.6 9.0
------------------------------------------------------------
The average grades above were calculated from channel samples
collected across the test drift faces and weight-averaged by
representative volume and specific gravity. Widths and lengths were
measured in the horizontal plane perpendicular to each other. This
test drift has yet to cross the entire mineralized body as
identified in SRK's 43-101 model of the zone.
The Exploration Plan
Management considers the Crescent to be a property with the
potential for the delineation of a world-class silver-mineralized
system. Factors on which this opinion is based include:
-- The property sits between two world-class silver deposits and adjoins
them both;
-- Silver-bearing veins strike from the Sunshine mine, across the large
Crescent land package, to the past-producing Bunker Hill mine;
-- The Crescent deposit is a past-producing silver deposit where only
limited exploration has been carried out;
-- Drilling at Crescent has identified a near-surface resource while past
mining at much greater depths indicates the potential for depth
continuity;
-- A small program of wide step-out, surface drilling has shown that silver
mineralization continues well away from the known resource;
-- Underground drilling has shown that known mineralization continues to
depth and along strike and is open in both dimensions;
-- Underground drifting has provided a platform for a much more extensive
underground exploration program which has the possibility of identifying
additional resources to depth and along strike.
In order to accomplish the goal of aggressively exploring the
Crescent prospect and building a much larger silver resource, while
minimizing the impact on diluting the Company's share structure,
Management has agreed on an exploration plan using cash flow
generated from test-mining production of South Vein-hosted,
identified silver mineralization. Thus, exploration and development
activities will be carried out in parallel.
Exploration activities will include:
-- continuing the drifting from various underground levels accessed by the
Countess decline, concurrent with the establishment of a secondary
escapeway and sub-level development
-- underground drilling to potentially augment the existing resource to
greater depths and along strike, with priority given to continuing to
drill, from underground, the down-rake continuation of the known, South
Vein resource
-- drilling the Alhambra structure from underground west of the historic
Crescent workings, as well as within a 1200 foot "gap" between upper and
lower historic workings where good potential exists for continuation of
the mineralization, continuing the surface drilling program to identify
additional mineralization along the westward projection of the South
Vein. An additional 2000 feet of South Vein strike potential exists on
the Company's property in addition to the initial 1500 foot step-out
drilling program already carried out.
The plan anticipates the completion of approximately 200,000
feet of diamond drilling, consisting of 80,000 feet from the
surface and 134,000 feet from underground drill stations.
Development Activities
A spiral ramp system will be developed in the footwall of the
South Vein resource area. Ramping down in spirals from the existing
Countess decline will proceed, while concurrently a 10 foot by 13
foot incline ramp will be driven from the surface to connect with
the Countess spiral. When complete, the second opening to the
surface will allow ventilation and serve as a secondary escapeway.
The ramp spirals will provide access for test drifting for grade
and morphology of mineralization at multiple elevations within the
South Vein resource area to determine the continuity, potential for
enhancement, and parameters of the mineralization to guide further
drilling and drifting.
A paste backfill plant will be constructed near the incline
portal.
Test Mining Metal Production to Offset the Cost of
Exploration
The Company has a joint venture with the New Jersey Mining
Company ("New Jersey"; the "New Jersey Agreement") to secure
near-term milling capacity for the Crescent (see press releases
dated October 7, 2010 and June 9, 2011). Mill expansion, including
equipment installation and fabrication of structures and conveyors
is nearing completion. Mine Fabrication and Machine, a business
unit of the company's wholly owned subsidiary, United Mine
Services, Inc., is performing much of the mill construction.
Commissioning is expected to start at the end of March 2011. The
joint venture agreement gives the Company an exclusive right to
7,000 tonnes per month of milling capacity, with first rights on
additional unused capacity.
The mill is located less than four miles from the Crescent
Mine.
The mill will initially process ore from test drifting on the
South Vein currently stockpiled at the New Jersey mill.
Concentrates produced by the milling of the underground
drifting-produced mineralization will be sold to Formation Metals
U.S. under an agreement signed in December 2011 (refer to news
release dated December 13, 2011). Formation's refinery is less than
three miles from the mill, virtually eliminating hauling costs.
The Company expects that the ore from underground test drifting
and stoping will provide cash flow to the Company which will offset
the cost of exploration development. Projected cash flow will cover
the cost of expanding the Crescent deposit and avoid the need for
further equity offerings during the period of the Plan.
An Integrated Company
USC CEO Graham Clark states: "The Board of Directors of the
Company is excited and extremely optimistic about our plans going
forward to explore, and test mine on a modest scale, the materials
generated from drifts and stopes within the South Vein area of the
Crescent Mine, while at the same time exploring farther afield for
the on-strike and down-dip extensions to this potentially extensive
silver-bearing system. We are grateful to have secured initial
funding from Hale to establish our Plan which, for the next four
years, will see aggressive exploration combined with cash flow from
mining to finance the exploration and broader understanding of the
system. We believe that the cash flow generated from mining will
offset the need to go to the financial markets and undertake a
public offering during this time, preserving and enhancing value
for the shareholders and providing us with first-hand experience
mining the deposit.
"USC management is looking forward to our Plan of combined
exploration and silver production to be the beginning of the next,
and most important period to date, in the evolution of the Crescent
deposit".
