Marketwired Canada
Levon Resources Ltd. (Levon) (TSX VENTURE:LVN)(FRANKFURT:LO9)(BERLIN:LO9) is
pleased to report the compiled assays from the first 30 core holes (15,787.6 m)
of the ongoing Cordero Phase 3 drill program, which began October 1, 2010 (Table
1 compiled assays (results from 7 holes pending in the lab), Table 2 hole
locations). The drill results expand both the Pozo de Plata Diatreme and Cordero
Porphyry Zone bulk tonnage Ag, Au, Zn, Pb discoveries at the Cordero Project,
located 35 km northeast of Hildalgo Del Parral in southern Chihuahua, Mexico.
Both discoveries remain open to expansion as Phase 3 continues. Hole location
maps, cross sections, core, project photos, and additional information are
posted on the Levon website (www.levon.com).
Drilling
Cordero Porphyry Zone
Phase 3 core holes are being drilled in three 1.4 km long, north-south drill
fences, in the Cordero Porphyry Zone to delineate the bulk tonnage
mineralization and test it at depth. A recent highlight is the best of three
broad, bulk tonnage intersections in core hole C10-87 (124 m grading 26.3 g/T
Ag, 0.019 g/T Au, 0.77% Zn, 0.60% Pb (67.8 g/T Ag equivalent) Table 1). Hole
C10-87 was a 150 m offset of holes C10-41 (170 m grading 17.33 g/T Ag, 0.03 g/T
Au, 0.638 % Zn, 0.438 % Pb (62.9 g/T Ag equivalent) news release of June 1,
2010) and C10-72 intercepts (Table 1) The Porphyry zone remains open and
requires continued step out drilling to delineate the mineralization.
The geology of mineralization is porphyry style in terms of its mode, geologic
controls, associated alteration and zoning patterns. The zoning patterns are
mapped across the NS drill sections in the core layout on the ground (arranged
as the holes appear on the cross sections). Granodiorite porphyry is a common
host rock. Mineralized granodiorite dikes cut mineralized rhyolite and dacite
porphyries of the felsic volcanic dome complex, the alteration and
mineralization patterns are helping guide the drilling. The assays (Table 1)
continue to confirm that Ag and Au values are associated with logged
argentiferous galena, which is commonly associated with sphalerite, and
occasionally iron rich sphalerite (marmatite).
Pozo de Plata Diatreme
Phase 3 offset drilling (typically 100 to 150 m hole spacing on a grid) N, SW, S
and SE of the Pozo de Plata Diatreme Phase 2 drill grid, is compiled for 22
holes in Table 1. The drill results delimit the zone to the NW (holes C10-63,
C10-65), but continue to expand the mineralized zone, particularly toward
discovery intercepts drilled in Phase 2 within the Josefina Mine Zone located
500 m SE (Phase 2 hole C10-23 yielded several broad intercepts, the best of
which is 116 m grading 49.7 g/T Ag, 0.10 g/T Au, 1.28 % Zn and 0.94% Pb, news
release of May 13, 2010).
Pozo de Plata Diatreme mineralized geology and host rocks are complex with cross
cutting relationships that document at least seven pulses of sphalerite and
galena rich mineralization that range from pre diatreme breccia (shalerite,
galena breccia clasts) to post diatreme breccia veins (diatreme breccia cut by
massive sphalerite veins). Ag, Au, Zn, Pb grades in the current drill results
(Table 1) are highest within and along the contact zones of particular rhyolite
porphyry (and to a lessor extent, dacite porphyry) breccia dikes, which
themselves have been incorporated into the diatreme breccias through entirely
gradational contact zones. Assays (Table 1) continue to document that Ag and
most Au values are associated with argentiferous galena commonly intergrown with
sphalerite and some iron rich sphalerite (marmatite) and barite, calcite veins
(particularly in the footwall of the diatreme breccia hosted mineralization).
"Now that porphyry controls and associated alteration zoning have been
recognized in the Cordero Porphyry target, we are attempting to use the porphyry
style zoning patterns to guide the drilling toward the center of the mineralized
system. This simple approach becomes complicated due to the presence of multiple
episodes of alteration and mineralization and by the presence of composite,
nested mineralized rhyolite and dacite stocks, and diatremes in the felsic
volcanic dome complex. The mineralized dome rocks are cut by mineralized dikes
of granodiorite porphyry at depth. The volcanic dome complex is mushroomed
shaped and partly floored by Cretaceous limestone country rocks. Our drills are
looking for the intrusive "stems" of the mushroomed intrusives, to test the
sources of the bulk tonnage mineralization beneath the discoveries. The stems
and their porphyry feeders may represent the ultimate upside of the mineralized
system," comments Vic Cheviillon, VP Exploration, Director, Levon.

Outlying Exploration Targets
The Phase 3 core drilling campaign (59,000 m planned, $14M program, news release
of September 30, 2010) began October 1, 2010 starting with two core drills and
expanded to four rigs to yield the 37 holes Phase 3 holes (15,787.6 m) drilled
by December 18, 2010. Phase 3 has now been ramped up to 5 core drills turning 24
hours per day, 7 days per week by HD Drilling, Mazatlan, Mexico. Phase 3
involves offset grid drilling in the two discovery areas, and exploration
drilling in outlying mine-scale target areas.
SJ Geophysics, Vancouver has completed about two thirds of a 3D induced
polarization (IP) survey over the Molina de Viento, Dos Mil Diez, Pozo de Plata
Diatreme Complexes, the Pastura Sur, and Cordero Porphyry Zone. The remaining IP
survey is slated for completion over the La Ceniza Stock in January. Current IP
results are being processed in 3D inversions, which will be integrated with the
project data utilizing Gocad 3D pattern recognition software in the field for
drill targeting. Initial 3D IP chargeability anomalies are defining drill
targets, which are being drill tested, particularly in covered areas. Field
follow up of recent IP results in a NW part of the Pozo de Plata Diatreme has
defined a rhyolite breccia dike swarm with strong pyryite silica alteration on
the surface, that is now being mapped, sampled and scheduled for drill testing
at depth. Two holes have been drilled in covered chargeability anomalies in the
Molina de Viento Caldera Diatreme Complex, 8 km SW of the Pozo de Plata Diatreme
discovery grid within the Cordero Porphyry Belt (assays pending).
Engineering Studies
Engineering studies toward producing a first 43-101 compliant mineral resource,
and then a Preliminary Economic Assessment, have been initiated by IMC and M3
engineering firms in Tucson, who are well experienced with Penasquito type
deposits. The initial petrographic metallurgical samples have been selected for
collection, to help guide bench scale testing. The in house block model of Phase
2 drill results by IMC helps guide Phase 3 offset drilling, along with continued
3D geologic and alteration modeling.
"The early Phase 3 results so far, are opening up rather than closing off the
discoveries, and they require continued offset and delineation drilling. This is
exactly why we have ramped up the drilling program. We are trying to realize the
Cordero upside as soon as we can, and at the same time advance the discoveries
toward the feasibility study stage. We believe our Cordero exploration results
over the last 23 months, continue to point to a major new bulk tonnage District
in Mexico. We are pleased and see a bright future for our shareholders,"
comments Ron Tremblay, President, CEO, Levon.
QA/QC Procedures and Reporting Parameters
All drill holes are started with HQ diameter core and then rarely reduced to NQ
diameter core depending on drilling conditions. The drill core is sawed through
its length and samples collected in continuous two-metre intervals. All drill
intercepts reported (Table 1) are core lengths and not true widths, which are
unknown. All of the samples are being prepared and analyzed by ALS Chemex at its
labs in Chihuahua, Mexico, and Vancouver, Canada respectively. Gold analyses are
being performed by 30-gram fire assay with an atomic absorption finish. Silver,
zinc and lead were analyzed as part of a multi-element inductively coupled argon
plasma ("ICP") package using a four-acid digestion with over-limit results being
reanalyzed with assay procedures using ICP-AES.
The company employs a rigorous quality assurance and quality control program
that include standardized material, blanks and duplicates. AMEC Americas Ltd.
has designed the QAQC protocol from a study and review of information provided
by the Joint Venture to AMEC. Independent Mining Consultants (IMC), Tuscon,
