Crown Gold Corporation ("Crown" or the "Company") (TSX VENTURE:
CWM) has received a Conceptual Decline & Development Report
from Golder Associates ("Golder") for underground mining of the
McLean "Main Lode" resource on Crown's Monte Cristo property in
Esmeralda County, Nevada. The study provides a preliminary
underground design to mine the existing National Instrument 43-101
compliant inferred resource of 226,000 ounces of gold grading 7.2
g/t gold at a 2.0 g/t cut-off contained in the Main Lode, the
steeply dipping part of the McLean deposit. This is designated by
Golder as "milling ore" to be treated at a custom offsite facility.
Golder did not review the NI 43-101 report on the potential
resources at Monte Cristo. The model was used as supplied.
The NI 43-101 compliant gold resources for the whole McLean
Lode, that includes both the Main Lode and "Upper Zone" resources,
are:
---------------------------------------------------
cut off g/t gm tonnes g/t ounces
---------------------------------------------------
2.0 7,377,274 1,025,685 7.2 237,548
---------------------------------------------------
1.0 8,673,975 1,923,349 4.5 279,302
---------------------------------------------------
0.5 9,475,041 3,158,347 3.0 306,787
---------------------------------------------------
The Golder design work used Vulcan mine planning and modelling
software after importing a SURPAC generated block model supplied by
Crown. The optimum design selected locates the portal on the
existing McLean open-pit wall at between 70 to 100 feet below
surface. A spiral ramp in the footwall east of the deposit would
provide access to the bottom of the current Main Lode resource,
approximately 800 ft deep. Lateral development levels would be
placed at 50 foot vertical intervals extending in a NE-SW direction
up to 600 ft along strike. From the development levels, crosscuts
into the resource would allow mining by cut and fill stoping.
Cost of the decline ramp, footwall and connection drifts,
equipment passing bays and 3 ventilation raises - a total of 27,083
feet of development is estimated to be $25.6 million, calculated at
$57 per ton with a total 448,700 tons excavated. The decline design
cross section size is 13.1 ft (4 m) in width and 16.4 ft (5 m) in
height with a minimum default curve radius of 50 ft and maximum
grades of 12% for all straight drift and decline segments and 10%
for all curves allowing for 45 ton haul truck and 19 ton LHD
equipment.
The proposed design allows for mine production to start after
construction of only approximately one third of the total ramp
constructed with development drifts providing access to the upper
part of the resource. This time period is estimated conservatively
at six months from commencement of construction.
Although not part of the conceptual study, Golder has indicated
that an estimated additional 41,000 ounces of gold, contained in
material grading between 1 g/t and 2 g/t gold, below mill grade
cut-off, would be excavated in the planned development. Golder
suggests that this low grade material may be economically treated
in an on-site heap leach operation to recover additional ounces of
gold. The study recommends that geotechnical work, a
hydro-geological study, ventilation analysis and review of heap
leach test work be completed to advance design from conceptual to
preliminary levels. Approximately 300,000 tons of oxide ore was
mined from the pit in the 1980's and leached on a nearby heap.
Additional gold above a 1 g/t gold cut-off occurs in mineralized
material in the shallow, flat lying McLean Upper Lode portion of
the deposit but drilling is too wide-spaced for 43-101 compliant
modeling. Management believes that up to an additional 250,000
ounces of gold may also be available from this material for on-site
heap leaching.
Crown Gold signed a memorandum of understanding with American
Mining Corporation ("AMC") on November 17, 2010 to secure milling
facilities for Monte Cristo ore. AMC's Silver Peak milling complex
is currently under development approximately 40 miles south of the
McLean resource.
Crown also recently signed a letter of intent with an arm's
length private Canadian company, Argentium Resources Inc.
("Argentium"), to sell Crown's Monte Cristo, Sugarloaf and Blue
Sphinx properties in Nevada for $16,000,000 in cash and securities
(see News Release of March 28, 2011). Closing is expected to be on
or about June 30, 2011.
About Crown
Crown Gold, formed last year by the amalgamation of Crown
Minerals and Gold Summit, is exploring for high grade gold and
silver deposits in Nevada and Ontario.
In Ontario, Crown has its McKenzie Island property at Red Lake
where a spring work program is being planned to follow up on its
successful drill program this past February that yielded promising
results, including 2.2 oz/gold over 3 feet (see Crown's news
release dated March 3, 2011). Crown's other northwest Ontario
properties are its Sakoose property near Kenora and its Surprise
Lake property in the Uchi Belt, east of Red Lake. In northeastern
Ontario, Crown holds three other strategic land positions: one
adjacent to Trelawney's Chester discovery near Gogama, another at
the old Stairs Mine near Matachewan and a third in the heart of the
Timmins camp.
In Nevada, in addition to its Monte Cristo, Sugarloaf and Blue
Sphinx properties, Crown has two other gold exploration properties,
Gold Springs and Black Warrior, each of which contains
well-defined, essentially undrilled, targets.
