VANCOUVER, British Columbia,
Jan. 25, 2012 /PRNewswire/ --
Berkwood Resources Ltd. (TSX-V SYMBOL:
BKR.V) ("Berkwood") announced on January 3, 2012 that it again controls 100% of
the Prospect Valley Gold Property. After regaining control of the
project, Berkwood reviewed previously published NI43-101 compliant
Mineral Resource estimates for the property (see Altair Ventures
news release dated October 19, 2011 at www.sedar.com) and is
formally reissuing these estimates now in Berkwood's name. The
North and South Discovery Zones host a combined inferred mineral
resource estimated at 166,000 ounces gold grading 0.511g/t gold
above a cut-off grade of 0.30g/t gold. The reissued NI
43-101 compliant report by Henry J.
Awmack and Gary H. Giroux
will be filed on www.sedar.com shortly.
The Prospect Valley Gold Property is road-accessible, three
hours driving time from Vancouver,
and situated in proximity to good infrastructure and logistics near
Merritt, British Columbia. It
covers 107 km(2) encompassing a number of structurally
controlled epithermal gold prospects with potential to host bulk
tonnage and/or high grade vein deposits. The NI43-101 compliant
Mineral Resource estimates were calculated on two of these gold
prospects, the North Discovery Zone and South Discovery Zone. The
zones remain open for expansion and the property is host to a
number of other gold prospects not yet drilled.
Mineral Resource Estimate Methodology
The Mineral Resource study used a database of 45 drill holes
totaling 6,940 metres completed between 2006 and 2010 and
containing 95 down hole orientation surveys and 3,609 assays. Using
a 0.04g/t gold cut-off, 2 three dimensional solids were built to
constrain the North and South Discovery zones. Drill holes
were then compared to these solids and individual assays were
tagged if inside or outside the solids. Of the individual
assay intervals within the mineralized solids, 95% were less than
2m in length. As such, uniform 2.5m composites were produced
that honoured the solid boundaries. No dilution was
incorporated. Grade continuity for gold was examined using
pairwise relative semi-variograms within the combined North and
South zone composites. The 2 domains were combined for
variography since they lined up along the Early Fault Zone and
Early Fault Zone Breccia. A block model with blocks of 10m x
10m x 5m in dimension was superimposed over the mineralized
solids. The average specific gravity of 2.55 g/cc was used to
convert volume to tonnes. Grades for gold were interpolated
into blocks containing some percentage of North or South zone
mineralized solids by ordinary kriging. For blocks in the North
Zone only North Zone composites were used and likewise for blocks
in the South Zone. The kriging exercise was completed in a series
of 4 passes with the search ellipsoid for each pass a function of
the semivariogram range.
Based on this study, the delineated mineralization of the North
and South Discovery Zones were classified as a NI43-101 compliant
inferred mineral resource. Although the drill density is not
sufficient to classify any material as measured or indicated, the
resource calculations tabulated below assumes one could mine to the
limits of the mineralized solids. A possible open-pittable economic
cut‑off grade of 0.3 g/tonne Au has been highlighted, although no
economic studies have been done to date. The effective date
for this reissued resource is June 30,
2011.

Henry J. Awmack, P.Eng. of Equity
Exploration Consultants Ltd. and Gary H.
Giroux, P.Eng. of Giroux Consultants Limited, both Qualified
Persons under the definition of Canadian National Instrument
43‑101, are responsible for the mineral resource information in
this new release. Both are independent of Berkwood applying all of
the tests in section 1.5 of NI 43‑101. The property was
visited by Mr. Awmack in July 2011. George Gorzynski, P.Eng., a Director of Berkwood
and a Qualified Person under the definition of Canadian National
Instrument 43-101, is responsible for the technical information in
this news release other than information directly related to the
mineral resource estimates.
Future Plans
These mineral resource estimates represent an initial
encouraging compilation for two partially drill tested gold
prospects on the Prospect Valley Property. These zones both remain
open for expansion to depth and along strike. Notably the gold
grade of the Discovery South Zone increases with depth where
additional drilling is proposed. A number of other gold
prospects and anomalies known on the property have yet to be
explored. Berkwood is now making plans for the 2012 exploration
season to expand the known gold zones and carry out exploration on
the balance of the large 107 km(2) property.
About Berkwood Resources
Berkwood now holds a 100% interest in the Prospect Valley
Gold Property near Merritt,
BC. To date, several areas of gold mineralization
have been identified on the 107 km(2) property. The majority
of historic drilling has taken place in the centre of the claim
block along a prominent north-northeast trending linear zone.
This drilling outlined NI43-101 compliant Mineral Resources
totaling 166,000 ounces grading 0.511 g/t gold above a
cut-off of 0.30g/t gold at the combined Discovery South and
Discovery North Zones. The zones remain open for expansion and
other known zones of gold mineralization have yet to be
drilled.
Berkwood also has a 100% interest in the Cimandiri Gold
Property in Indonesia, located
120km south of Jakarta,
approximately 3 hours driving time. Railway lines are nearby,
with the closest rail station located only 8km from the property.
The project is located 9km southwest of the Cikondang Gold
open pit mine. Berkwood has carried out initial mapping and
geochemical sampling during the first phase of exploration and will
continue to report material results as they are received.
