Marketwired Canada
Lero Gold Corp. ("Lero", or the "Company") (TSX VENTURE:LER) is pleased to
report a National Instrument 43-101 compliant resource estimate for its Karchiga
VMS deposit northeast Kazakhstan.
The resource incorporates the 1,879m of confirmation diamond drilling completed
by Lero in Q4 2007 and 86 historical Soviet diamond drillholes and trenches
totalling 10,330m. At a 0.50% copper cut-off, the Indicated resource is 4.75Mt @
2.46% Cu while the Inferred resources total 2.81Mt @ 1.81% Cu.

Karchiga Central lodes contain 4.75Mt @ 2.46% Cu of the resource within sulphide
(Indicated) and 0.71Mt @ 1.49% Cu within oxide (Inferred) material at a 0.50% Cu
cut-off. The balance of the resource is contained within an Inferred sulphide
resource at Karchiga northeast. The north eastern lodes, which are blind to
surface, are located some 200m across strike and lie 150m stratigraphically
above the Karchiga Central mineralised zone.
The mineralisation is located within a series of stacked shallow-dipping massive
and disseminated sulphide bodies, primarily consisting of
chalcopyrite-pyrrhotite and pyrite mineralisation. The lodes have a strike of in
excess of 1km and are intersected at depths reaching 200m. The majority of the
high grade sulphide mineralisation is concentrated within 100m from surface.
Indication of the presence of easterly-plunging higher grade copper shoots is
evident from the modelling completed to date and follow-up drilling is planned
to evaluate the down dip potential during the 2008 field season.
The resource was calculated using Ordinary Kriging on composite drillhole
samples selected within a 0.5% Cu wireframe. All wireframe models were
constructed from interpretation of geology and grade boundaries and used to
assign block categories within the grade interpolation model. Material types and
samples data was subsequently extracted and subset within discrete lodes and
grade interpolation constrained to each individual lode separately. A total of
seven separate wireframes were constructed to constrain drillhole data. Specific
gravity measurements were carried out for the different material types collected
from Karchiga diamond drill core and an in-situ bulk density value assigned to
the block model.
CEO of Lero, Dr Alexander Yakubchuk commented:
"We are pleased to receive such positive results from our initial resource
calculation, generally in line with the historical estimate and exceeding it in
terms of tonnage. Not many current exploration projects worldwide return such
high copper grades, amenable to potential open pit extraction. In addition, only
5% of the entire licence territory was explored by Lero to date and we still
have a lot of further exploration potential based on geochemical and geophysical
anomalies within the licence territory."
Chairman of Lero, Dr Sergey V. Kurzin commented:
"These results, indicating that Karchiga contains in excess of 258 million
pounds (117,000 t) of high-grade copper metal, give us a solid foundation for
undertaking prefeasibility and scoping studies in the immediate future, which,
if prove positive, would allow Lero to fast track the project to construction
and production within three years."
