       RUSORO LAUNCHES TAKE-OVER BID FOR GOLD RESERVE

December 15, 2008                                                                             Trading Symbol (TSX-V):RML

Vancouver, Canada?Rusoro Mining Ltd. (TSX-V:RML) (?Rusoro? or the ?Company?) today announced a

take-over bid (the "Take-Over Bid") for Gold Reserve Inc. ("Gold Reserve", TSX:GRZ ? AMEX:GRZ). 

Rusoro is offering Gold Reserve shareholders and equity unit holders (collectively, the ?Gold Reserve

Equityholders?) 3 Rusoro common shares for each Gold Reserve Class A common share and each Gold

Reserve equity unit (collectively, the ?Gold Reserve Equity?). The offer values Gold Reserve at C$1.08 per

each Class A common share and each equity unit, and represents a premium of 140% based on the

December 12, 2008 closing prices for Rusoro and Gold Reserve on the TSX Venture Exchange (?TSXV?)

and the Toronto Stock Exchange (?TSX?), respectively, and a premium of 209% based on the volume-weighted

average trading prices for Rusoro and Gold Reserve for the previous 30 trading days on the TSXV and the

TSX, respectively.

Andre Agapov, Chief Executive Officer of Rusoro said, ''A business combination between Rusoro and Gold

Reserve creates the premier Venezuelan gold company and allows us to use our extensive in-country experience

to unlock the inherent value of the Brisas Project for the benefit of all shareholders.  Not only would Gold

Reserve Equityholders benefit from the existing production at our Choco 10 and Isidora mines operating in

Venezuela, they will also continue to participate in the development of the Brisas Project through significant

ownership in the combined company.  Gold Reserve?s Choco 5 project is contiguous to our Choco 10 operations

and Gold Reserve?s Brisas Project is approximately 10 kilometres from our Yuruan property - the logical

combination of our companies is expected to create real and valuable synergies. We are delighted to present this

premium offer directly to Gold Reserve Equityholders and we see significant opportunities to both expand

production at our existing operations and unlock the permitting deadlock that has plagued the timely development

of the Brisas Project.  The KM88 region in Venezuela is one of the world?s great gold mining regions and the

time has come for its future to be guided by a team that has proven its ability to get its assets permitted and

operating in Venezuela.?

Mr. Agapov added, ?This is a logical combination.  I encourage Gold Reserve Equityholders to contact their

Board of Directors to support this opportunity.  Further, I invite the Gold Reserve Board of Directors to contact us

to open a constructive dialogue.?

The proposed combination of Rusoro and Gold Reserve would offer Gold Reserve Equityholders a number of benefits:

?          Compelling Premium.  On December 12, 2008, which was the last trading day prior to today?s announcement of

       the Take-Over Bid, the closing price of the Gold Reserve Shares listed on the TSX was C$0.45 and on the NYSE

       Alternext (AMEX) was US$0.39.  Rusoro is offering C$1.08 per each Gold Reserve share and each Gold Reserve

       equity unit, based on Rusoro?s closing share price on the TSXV that same day.  This offer represents a premium

       of approximately 140%, using the December 12, 2008 closing prices of Rusoro and Gold Reserve on the TSXV

       and TSX, respectively.  Based on the volume-weighted average price of the Rusoro Shares on the TSXV for the

       30 trading days ended December 12, 2008, the Offer represents a premium of approximately 209% over the

       volume-weighted average price of the Gold Reserve Shares on the TSX for the same period.

?          Immediate Production.  Rusoro is expected to produce in excess of 100,000 attributable gold ounces in 2008

       from its existing proven and probable reserves.  Management is currently developing expansion plans at

       Choco 10 and Increible 6 that are expected, together with Rusoro's San Rafael/El Placer and Isidora operations,

       to significantly increase attributable gold production.  See further information on Rusoro?s technical information

       at the end of this press release.

?          World Class Reserve and Resource Base.  The combined company would have 12.2 million ounces of proven

       and probable gold reserves.  Measured and indicated resources, inclusive of reserves, would total 18.9 million

       ounces of gold.  The combined company would also have additional resources of 9.3 million inferred gold

       ounces.  In addition, the Brisas Project contributes 1.4 billion pounds of copper in proven and probable reserves. 

       See further information on the companies? technical information at the end of this press release.

?          Ongoing Participation in Brisas..  Based on the 3:1 exchange ratio, Gold Reserve Equityholders would collectively

       own approximately 30.4% of the combined company on an issued share basis.

?          Opportunity to Consolidate the KM88 Region.  Rusoro has proven itself as a Venezuelan gold consolidator

       through the successful acquisition of both Gold Fields' Choco 10 mine and Hecla Mining's Isidora mine. 

       Rusoro will explore the opportunity to further consolidate the world-class KM88 Region in Bolivar State, Venezuela.

?          Established Relationship with the Venezuelan Government.  Rusoro has established the first mixed enterprise joint

       venture of its kind with the Venezuelan government in the mining industry by agreeing to form a joint venture over the

       Isidora gold mining assets that Rusoro recently acquired from Hecla.

?          Concrete Synergies.  The logical combination of Rusoro and Gold Reserve will not only produce corporate synergies

       through the rationalization of head offices, regulatory filing requirements and executive teams, the strictly Venezuelan

       location of all material operations will enable the combined company to optimize in-country operations as well. 

       Gold Reserve's Choco 5 property is adjacent to Rusoro's Choco 10 mine and Gold Reserve's Brisas property is 10

       kilometres south of Rusoro's Yuruan property, all in Bolivar State, Venezuela..  Rusoro expects to reduce duplicated

       in-country costs while optimizing operations including drilling, the use of construction and mining equipment, ore

       processing opportunities as well as regulatory and logistical requirements surrounding imports and permitting.

?          Full Exposure to Gold Price.  Based on Gold Reserve?s publicly available information, none of the gold production

       of the combined company is hedged..

?          Tax Efficient Structure.  The Take-Over Bid has been structured as an all-share offer that will allow certain Gold

       Reserve shareholders who tender to the offer to do so on a tax efficient basis.  Canadian resident Gold Reserve

       shareholders may receive Rusoro shares on a tax-deferred basis.  Subject to the Passive Foreign Investment Company

       rules, U.S. resident Gold Reserve shareholders may also receive tax-deferral treatment if the Take-Over Bid is a qualified

       reorganization under U.S. federal tax law.

?          Optimization and Consolidation Opportunities.  If the offer is accepted and Rusoro acquires all of the outstanding

       Gold Reserve Equity, Rusoro intends to:  (a) expedite its development and expansion plans at its Choco 10 mine and

       Increible 6 project; (b) identify opportunities to optimize the development of Gold Reserve's Choco 5 project which is

       adjacent to Rusoro's Choco 10 mine; and (c) obtain the requisite development permits in respect of the Brisas Project in

       order to recommence construction in a timely manner.

?          Ability to deliver results in Venezuela.  Since commencing Venezuelan operations, Rusoro has been able to:

o        Develop an extensive land package with 2.0 million proven and probable gold ounces in reserves, and a resource

       (inclusive of reserves) of 7.1 million measured and indicated gold ounces.  Rusoro also has an additional 7.0 million

       ounces of gold in inferred resources;

o        Permit and develop its San Rafael/El Placer project which is expected to reach commercial production in 2010;

o        Restart the Choco 10 mine acquired from Gold Fields after it had been effectively shut down as a result of both  

       permitting and labour issues; and

o        Restart the Isidora mine acquired from Hecla after it had been effectively shut down as a result of both permitting

       and labour issues.

                                                THE TAKE-OVER BID WILL BE OPEN FOR ACCEPTANCE UNTIL

                                            12:00 MIDNIGHT EASTERN TIME AT THE END OF JANUARY 21, 2009,

                                                 UNLESS THE BID IS EXTENDED OR WITHDRAWN BY RUSORO.

The Take-Over Bid will be subject to customary conditions, including: that a minimum of 66 2/3% of the outstanding Gold Reserve

shares and 66 2/3% of the outstanding equity units on a fully-diluted basis, respectively, are tendered to the offer; the execution

of a supplemental indenture in respect of Gold Reserve?s 5.50% Senior Subordinated Convertible Notes due June 15, 2022; and the

waiver or setting aside of Gold Reserve?s shareholder rights plan.

Technical Disclosure Relating to Rusoro's and Gold Reserve's Reserve Assets

The information presented in the following tables is derived from information and data contained in technical reports, all of which are listed following the tables, prepared pursuant to NI 43-101.

Mr. Gregory Smith, P. Geo., the Vice-President Exploration of Rusoro, is the "Qualified Person", as defined in NI 43-101, and is responsible for the scientific and technical aspects of this

press release as they relate to Rusoro's assets.  Information concerning Gold Reserve's assets is taken from Gold Reserve's public filings. 

NOTES:

All Resources reported include Reserves. 

(a)     Resources for Las Brisas are taken from Gold Reserve?s public filings and are reported at a cut-off of 0.4 g/t AuEq where AuEq = Au (gpt) + Cu (%)*1.16.

Notes for all Rusoro Resources and Reserves:

(1)           Reserves and resources are NI 43-101 compliant and follow the definitions for proven and probable reserves and measured, indicated and inferred resource established

               by the CIM.

(2)           Mineral resource estimates which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by

               environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

(3)           The quantity and grade of reported inferred resources in these estimates is uncertain in nature and there has been insufficient exploration to define these inferred resources

               as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured category.

(4)           Choco 10 reserves are reported as 100%; 95% are attributable to Rusoro.   Isidora reserves are 100% attributable to Rusoro until the Mixed Enterprise with MIBAM is

               established.  All resources reported include reserves.

The key assumptions, parameters and methods used for each of the resource and reserve estimates are summarized in the following table:

Cautionary Note Regarding Forward-Looking Statements

This press release, the Take-Over Bid and Circular, including the schedules attached therein, the pro forma consolidated financial statements of the Company, and

some of the material incorporated by reference into the Circular, contain certain forward-looking information and forward-looking statements, as defined in

 applicable securities laws (collectively referred to as ''forward-looking statements'').  Forward-looking statements include possible events, statements with respect to

possible events, the proposed transaction, the business, operations and financial performance and condition of each of Rusoro and Gold Reserve and the proposed

combined company, the future price of gold, the estimation of mineral reserves and resources, the realization of mineral reserve and resource estimates, the timing

and amount of estimated future production, costs of production, expected capital expenditures, costs and timing of the development of new deposits, success of

exploration, development and mining activities, permitting time lines, currency fluctuations, requirements for additional capital, government regulation of mining

operations, environmental risks, unanticipated reclamation expenses, title disputes or claims, and limitations on insurance coverage.

 The words ''plans,'' ''expects,'' ''is expected,'' ''scheduled,'' ''estimates,'' ''forecasts,'' ''intends,'' ''anticipates,'' or ''believes,'' or variations of such words and phrases or

 statements that certain actions, events or results ''may,'' ''could,'' ''would,'' ''might,'' or ''will be taken,'' ''occur'' and similar expressions identify forward looking statements.

Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by Rusoro as at the date of such

 statements, are inherently subject to significant business, economic, social, political and competitive uncertainties and contingencies and other factors that could

cause actual results or events to differ materially from those projected in the forward-looking statements.  The estimates and assumptions of Rusoro contained or

incorporated by reference in the Circular which may prove to be incorrect, include, but are not limited to, (1) that Rusoro will be successful in acquiring 100% of

the outstanding Gold Reserve Equity, (2) that all required third party regulatory and governmental approvals to the Take-Over Bid will be obtained and all other

conditions to completion of the transactions will be satisfied or waived, (3) there being no significant disruptions affecting operations, whether due to labour disruptions,

supply disruptions, power disruptions, damage to equipment or otherwise; (4) permitting, development, expansion and power supply proceeding on a basis consistent with

Rusoro?s current expectations; (5) permitting and development proceeding on a basis consistent with Rusoro's current expectations; (6) the exchange rate between the

Canadian dollar, the Venezuelan Bolivar and the U.S. dollar being approximately consistent with current levels; (7) certain price assumptions for gold; (8) prices for and

availability of natural gas, fuel oil, electricity, parts and equipment and other key supplies remaining consistent with current levels; (9) production forecasts meeting

 expectations; (10) the accuracy of Rusoro's current mineral reserve and mineral resource estimates; and (11) labour and materials costs increasing on a basis consistent

with Rusoro's current expectations.

Known and unknown factors could cause actual results or events to differ materially from those projected in the forward-looking statements.  Such factors include, but are

 not limited to, fluctuations in the currency markets; fluctuations in the spot and forward price of gold or certain other commodities (such as diesel fuel and electricity);

changes in interest rates; disruption to the credit markets and delays in obtaining financing; inflationary pressures; risks arising from holding derivative instruments

(such as credit risk, market liquidity risk and mark-to-market risk); changes in national and local government legislation, taxation, controls, regulations and political

or economic developments in Canada, Venezuela or other countries in which Rusoro does or may carry on business; business opportunities that may be presented to, or

 pursued by Rusoro, Rusoro's ability to successfully integrate acquisitions; operating or technical difficulties in connection with mining or development activities; actual results

of exploration activities; the possibility of cost overruns or unanticipated expenses; employee relations; the speculative nature of gold exploration and development, including

the risks of obtaining and renewing necessary licenses and permits; the impact of Venezuelan law on Rusoro?s operations; diminishing quantities or grades of reserves; adverse

changes in our credit rating; contests over title to properties, particularly title to undeveloped properties; and the occurrence of natural disasters, hostilities, acts of war or

terrorism.  In addition, there are risks and hazards associated with the business of gold exploration, development and mining, including environmental hazards, industrial

accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold bullion losses (and the risk of inadequate insurance, or inability to obtain insurance, to

cover these risks).  The following factors, amongst others, related to the business combination of Rusoro and Gold Reserve could cause actual results to differ materially from

forward-looking statements, including those contained in the Circular: the Rusoro shares issued in connection with the Take-Over Bid may have a market value lower than

expected; the business of Rusoro and Gold Reserve may not be integrated successfully or such integration may be more difficult, time-consuming or costly than expected;

and the expected combination benefits from the combination of Rusoro and Gold Reserve may not be fully realized or not realized within the expected time frame.  All of the

forward-looking statements made in the Circular are qualified by these cautionary statements and those made in the Circular itself.  These factors are not intended to represent

a complete list of the factors that could affect Rusoro and the combination of Rusoro and Gold Reserve.  Additional factors are noted elsewhere in the Circular and in the

documents incorporated by reference therein.  Although Rusoro has attempted to identify important factors that could cause actual results or events to differ materially

from those described in forward-looking statements, there may be other factors that could cause results or events not to be as anticipated, estimated or intended.  There can be no

assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. 

Accordingly, undue reliance should not be placed on forward-looking statements.  Rusoro undertakes no obligation to update publicly or otherwise revise any forward-looking

 statements or the foregoing list of assumptions or factors, whether as a result of new information or future events or otherwise, except as may be required in connection with a

 material change in the information disclosed in the Circular or as otherwise required by law.

Cautionary Note Concerning Resource Estimates

Information in this press release and the Circular, including information incorporated by reference, and disclosure documents of Rusoro that are filed with Canadian securities

regulatory authorities concerning mineral properties have been prepared in accordance with the requirements of securities laws in effect in Canada, which differ from the

requirements of United States securities laws.

Without limiting the foregoing, these documents use the terms "measured resources", "indicated resources" and "inferred resources".  Gold Reserve Equityholders in the United

States are advised that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them.  Under United States standards, mineralization

may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve

determination is made. United States investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into reserves.  Further,

inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part

of the inferred resources will ever be upgraded to a higher resource category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility

or pre-feasibility studies, except in rare cases. Therefore, United States investors are also cautioned not to assume that all or any part of the inferred resources exist, or that they can

be mined legally or economically.  Disclosure of "contained ounces" is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report

"resources" as in place tonnage and grade without reference to unit measures. Accordingly, information concerning descriptions of mineralization and resources contained in these

documents may not be comparable to information made public by United States companies subject to the reporting and disclosure requirements of the SEC. 

National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") is a rule developed by the Canadian Securities Administrators, which has established

 standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.  Unless otherwise indicated, all resource estimates of Rusoro

contained in this press release and the Circular, including information incorporated by reference, have been prepared in accordance with NI 43-101 and the Canadian Institute of

Mining, Metallurgy and Petroleum Classification System.
