Tassawini Gold Project - 100% Takara (pending closing with Victoria)
Takara Acquisition of Guyana Assets from Victoria Gold Corp.
Takara has entered into an agreement with Victoria Gold Corp. to acquire a
subsidiary of Victoria (StrataGold Guyana Inc.) that holds two advanced stage
gold projects within the Guyana Shield, Guyana. Total consideration to Victoria
will be the issuance of 56% of the outstanding shares of Takara on the date of
closing. The two projects are a 100% interest in the Tassawini Gold Project and
a 31.96%* interest in the BRL Venture. The BRL Venture is a joint venture with
Newmont Overseas Exploration Limited, a subsidiary of Newmont Mining
Corporation, which is currently undergoing a trenching and diamond drilling
program that is being operated by Newmont. These two advanced stage gold
projects have significant exploration upside in addition to potential near-term
future gold production. These projects were originally explored and acquired by
StrataGold Corporation and its subsidiary’s between 2004 and 2009.
*as at December 31, 2008.
Location
Tassawini is situated in the Barima-Waini District of Northwestern Guyana, South
America. It is located approximately 170 kilometres northwest of the capital,
Georgetown and is centered at latitude 7º 30' N and longitude 59º 35' W. The
property is accessible via a private airstrip located on the property and by
barge.
History
Tassawini is an advanced stage gold exploration property centered on the site of
the former producing Tassawini Gold Mine where, between 1907 and 1914, an
estimated 11,200 ounces of gold were recovered. Prior to acquisition, the
property was subject to extensive exploration estimated to have cost over US$10
million. This exploration included a 116 hole diamond drilling program by
Paranapanema Mineracao S.A. during the period from 1986 to 1988, followed by a
pre-feasibility study completed by Kilborn Limited from Canada with a mineable
reserve estimate of 1,422,678 tonnes grading 1.97 g/t gold. In 2001, Tassawini
Gold Mines report a resource estimate of 2.74 million tonnes grading 2.2 to 2.7
g/t gold. (Both of these estimates are provided for historical purposes only and
are not NI43-101 compliant).
Underlying Purchase Agreement
The Tassawini Prospecting License (PL) was granted to StrataGold Guyana Inc.
(SGI) on March 15, 2005 by the Guyana Geological and Mines Commission (the
"GGMC"). The Anaturi PL is 100% owned by StrataGold Guyana Inc. and covers
approximately 4,836 hectares (ha) save and except for three small scale claims,
Christine 1-3, totalling approximately 30 ha. The Anaturi PL, which is
contiguous to the Tassawini PL to the northeast, has an effective date of
November 25, 2005 with a date of grant of November 22, 2005 by the GGMC. On June
14, 2007, the Corporation announced that it had satisfied its earn in
obligations under the option agreement dated June 10, 2004 relating to the
Tassawini property (the "Tassawini Option Agreement") and, as a result, acquired
a 100% interest in the property, subject to certain rights retained by the
vendor, Mr. Wayne Vieira, described below.
The vendor retains a 2.5% net smelter returns ("NSR") royalty that can be
purchased at anytime at StrataGold's option for US $4.0 million. The vendor also
retained the right to mine any known alluvial and tailings gold deposits, which
right could be purchased by StrataGold at anytime for US$500,000. On July 13,
2007, StrataGold announced it had entered into an agreement to buy-out the
alluvial gold mining rights from the vendor for US$500,000 in two instalments of
US$250,000. StrataGold has fulfilled the payment obligations to the vendor for
the alluvial gold mining rights. Upon exercise of the Tassawini Option, the
Company was required under the Tassawini Agreement to make all reasonable
efforts, consistent with technically-and-economically prudent industry
practices, to complete a 'Feasibility Study' on the property within 18 months. A
subsequent amendment extended the delivery date of the 'Feasibility Study' to 24
months. A further amendment was signed on March 26, 2009 to extend the delivery
of the 'Feasibility Study' from 24 months to 60 months (June 8, 2012) in
exchange for monthly payments of US$6,000.
Land
The Tassawini PL is 100% owned by StrataGold Guyana Inc. ("SGI") a wholly owned
subsidiary to be acquired by Takara and covers approximately 4,814 ha and
surrounds and encompasses the four Mining Permits (MP) (covering a total area of
1,381 ha) which make up the property. The area is covered by two contiguous
adjoining Prospecting Licences (the "Tassawini PL" and the "Anaturi PL") and
four Medium Scale Mining Permits ("MSMP's") which lie within the outline of the
Tassawini PL, and which have a total area of 9,650 ha.
Geology
The projects to be acquired by Takara are all located within the northern
Archaean - Proterozoic Guiana Shield, which is characterized by highly
prospective granite-greenstone-formations similar to those in Canada, Southern
and Western Africa and Australia. The greenstones comprise intensely folded and
metamorphosed sequences of volcanic and sedimentary rocks (Barama-Mazaruni
Supergroup ca 2200-2000 Ma) originally deposited in continental shelf and deeper
oceanic environments. These sequences are intruded by and interfolded with
granitic rocks (Younger Granites Groups). Later gabbro and dolerite dykes and
sills (Avanavero Dolerite ca 1760 Ma) cut across all the older rock formations.
Global reconstructions of the Guiana Shield and the Birimian Shield of West
Africa strongly suggest that these continental terrains are geologically related
and developed synchronously (at the same time), and that the two shields would
have similar endowments of precious metal. The presence and distribution of
primary and alluvial gold deposits in the Northwest District of Guyana adds
further support for a hereditary connection with the Birimian meta-sedimentary
terrains of West Africa, where some of the world's richest gold deposits have
been discovered. Structurally-controlled epigenetic gold mineralization occurs
as mesothermal and hypothermal lode gold deposits in bedrock and saprolite,
characterized by silica-graphite-carbonate-pyrite-arsenopyrite-pyrrhotite
mineral assemblages.
The Guiana Shield hosts the Omai deposit in Guyana, Rosebel in Suriname and Las
Cristinas in Venezuela. The Guyana Shield is similar to the Birimian Greenstone
Belt of West Africa, which hosts several large gold deposits including: Sadiola,
Yatela, Morila and Syamain, Mali; Siguiriin, Guinea; and Obuasi, Bogosu, Prestea,
Bibianiin, Ghana.
Mineralization
Gold mineralization at Tassawini is structurally controlled and
stratigraphically situated near a sheared boundary between the Lower Barama
Group and the Upper Mazaruni Group. Manganese rich metasedimentary rocks which
characteristically occur near the top of the Barama Group volcano-metasedimentary
stratigraphy are present at Tassawini. Proto lithologies indicate a turbidite
sedimentary environment with deposition of various fine- to coarse-grained
greywacke sediments, ranging from predominantly low-energy cherts, mudstones and
siltstones, to sandstones and localized higher energy matrix- and clast-supported
conglomerates. Syntectonic granodiorite dikes and sills have intruded the
metasedimentary sequence and have been interfolded with it. Regional
metamorphism has affected the whole package of rocks and ranges from lower to
upper greenschist to possible low amphibolite grade. The sedimentary-intrusive
package has been gently to isoclinally folded during regional N-S to NW-SE
compression, with the development of linear and rod-like zones of intense
folding and transposition of bedding and foliation. Gold mineralization has been
focused into these high strain zones which cross-cut original stratigraphy but
favor the finer grained, more intensely deformable proto-lithologies, and into
other structural traps and extension zones such as parasitic fold hinges and
intrusive contacts. The gold bearing mineralogical assemblage includes
graphite-carbonate-pyrite-arsenopyrite-pyrrhotite assemblages along with
multistage, strongly deformed and brecciated sygmoidal quartz veins, zones of
silica flooding and sericite alteration. Metamorphic petrology indicates that
the favorable host rocks occur at or close to the lower -- upper greenschist
boundary. Intense tropical weathering has formed a deep saprolite profile within
the mineralized area, up to 75 m vertical depth.
Resources
Mineral Resource estimate includes the following select zones: Tassawini East,
Tassawini West (including Mine Creek), Tassawini South, Black Ridge and Sonne,
and is tabulated below, reported at 0.50 g/t gold cut-off. This resource
estimate was previously reported by SRK Consulting (Canada) Inc. (“SRK”) of
Toronto, Ontario for StrataGold Corporation in June 2008 and has been restated
by SRK for Takara on February 10, 2010.

Historical Work Programs
Since acquiring the property in June 2004, StrataGold spent approximately $26.3
million on exploration and development of Tassawini. This work consisted of
geophysics, mapping, sampling, metallurgical studies, environmental baseline
work, petrographical studies, construction of a modern camp and over 110,000
metres (m) has been drilled on the property to date including 425 diamond drill
holes (56,504 metres) and 1,436 reverse circulation holes (53,015 metres).
Exploration has confirmed several large zones of gold mineralization and defined
compliant ounces around the areas of the historical workings.
Outside of the 30 ha where the Tassawini Deposit is contained, over 640 ha of
gold soil geochemical targets were identified for follow-up in 2007. A total of
60.4 line kilometers (km) of induced polarization geophysical surveys were
completed in 2007 around the Tassawini Deposit, Kathmandu, Clutch, Matahari,
Stamp Mill, Dome and Impasse targets. Trenching, detailed mapping, reverse
circulation and diamond drilling was also carried out on targets for further
definition. Diamond drilling in and around the Tassawini Deposit following up on
IP targets discovered a new zone of mineralization 250m southwest of the main
deposit. This discovery did not relate to previous drilling and represents a new
exploration technique for defining gold resources. Reverse circulation and
trenching from 2007 also delineated two parallel contiguous zones of
mineralization at surface at Sonne North and South. Diamond drilling further
defined a new zone at Sonne South that intersected gold mineralization in
saprolite and bedrock with the zone remaining open in all directions. RC
drilling at the nearby Clutch anomaly also aided in the discovery of three new
gold zones. Drilling has demonstrated that gold mineralization at Clutch is
highly folded with some holes terminating in mineralization.
Exploration in 2008 at Tassawini and Anaturi continued with trenching and
geological mapping mainly at the satellite targets at Clutch and Matahari.
Numerous targets have been identified that require follow up exploration work.
Tassawini, Sonne and seven untested surface geochemical anomalies are open for
expansion and will be subject to follow up work.
Future Work Plans
Since the announcement of the sale of the Guyana assets to Takara, engineering
groups have been approached to prepare a NI 43-101 Preliminary Economic
Assessment Report on the Tassawini Gold Project which would include a resource
estimation review, pit optimization, preliminary mine plan and schedule,
geotechnical review and preliminary tailings construction, pit slope
determinations, environmental permitting studies, mine closure assessment,
infrastructure, capital and operating costs, social issues and economic
modeling. The Preliminary Economic Assessment Report would be used to guide a
large scale mining operation on the Tassawini Gold Project.
In addition, exploration including geological mapping, trenching and sampling
will target the numerous untested geochemical targets on the property.
