Venezuela Government: Opposes War, But Won't Use Oil As Weapon

Source Monday March 31, 10:50 PM

CARACAS -(Dow Jones)- Despite staunch opposition against the U.S.-led war in Iraq, Venezuela won't use oil as a weapon and will continue to be a secure supplier of crude oil and refined products to the U.S., the nation's Oil Minister said Sunday.

"The position that we have always maintained within OPEC, and that is the policy of our government, is that oil should not be used as a political weapon," Rafael Ramirez said in a televised interview.

Venezuelan President Hugo Chavez has sharply criticized the attack of U.S. and British forces on the regime of Saddam Hussein. Venezuela is one of the top four suppliers of crude oil and products to the U.S. and supplies a bit more than 13% of all U.S. imports.

Venezuela has made efforts to improve its image as a secure supplier after a devastating strike hit the nation's oil company from December last year until February this year.

About 35,000 employees walked off their jobs in early December, crippling oil production and exports. Only during the past few weeks has the oil sector shown signs of significant recovery. Production is estimated at somewhere between 2.4 million and 2.8 million barrels per day by secondary sources, while oil exports are seen slightly above 2 million b/d. Venezuela's pre-strike production level was 3 million b/d.

Crystallex encouraged by Las Cristinas resource report

2003-03-31 10:32 ET - News Release <a href=new.stockwatch.com>Mr. A Richard Marshall reports

CRYSTALLEX ANNOUNCES RESERVE AND RESOURCE ESTIMATES FOR LAS CRISTINAS

Mine Development Associates (MDA) of Reno, Nev., has completed reserve and resource estimates for Crystallex International's Las Cristinas gold deposits located in Bolivar state, Venezuela.

MDA report highlights:

measured and indicated resources: 439 million tonnes at 1.09 grams of gold per tonne (15.3 million ounces);

inferred resources: 208 million tonnes at 0.91 grams of gold per tonne (6.1 million ounces); and

proven and probable reserves: 224 million tonnes at 1.33 grams of gold per tonne (9.5 million ounces).

Mineralization remains open at depth

"The release of the MDA data represents a major milestone for our company, our shareholders and the people of Bolivar state, Venezuela, who will directly benefit from this project," said Marc J. Oppenheimer, president and chief executive officer of Crystallex. He continued, "The data confirm that Las Cristinas is one of the world's largest undeveloped gold deposits with excellent potential to grow in size. More specifically, the report concludes that with additional drilling, at least a portion of inferred resources will likely be upgraded to the measured and indicated categories, which should add to the reserves. These data certainly validate the intensive efforts over the past several years, which resulted in Crystallex securing the exclusive mining rights to this valuable deposit."

Following the signing of an agreement with the Venezuelan Guayana Corporation (CVG) in September 2002 to control and develop the Las Cristinas 4, 5, 6 and 7 goldmines, Crystallex closed a private placement the same month to raise US$11.9 million to pay a total $15 million for use of mine data, feasibility and other studies and infrastructure held by CVG.

Crystallex Announces Reserve and Resource Estimates for Las Cristinas

<a href=www.stockhouse.ca>StocHouse 3/31/03

Crystallex International Corporation (TSX, Amex: KRY) announced today that Mine Development Associates ('MDA') of Reno, Nevada has completed reserve and resource estimates for the Las Cristinas gold deposits located in Bolivar State, Venezuela.

MDA Report highlights:

-- Measured and Indicated Resources: 439 million tonnes at 1.09 grams of gold per tonne (15.3 million ounces)

-- Inferred Resources: 208 million tonnes at 0.91 grams of gold per tonne (6.1 million ounces)

-- Proven and Probable Reserves: 224 million tonnes at 1.33 grams of gold per tonne (9.5 million ounces)

-- Mineralization remains open at depth

'The release of the MDA data represents a major milestone for our Company, our shareholders and the people of Bolivar State, Venezuela who will directly benefit from this project,'said Marc J. Oppenheimer, President and CEO of Crystallex. He continued, 'The data confirms that Las Cristinas is one of the world's largest undeveloped gold deposits with excellent potential to grow in size. More specifically, the report concludes that with additional drilling at least a portion of Inferred Resources will likely be upgraded to the Measured and Indicated categories which should add to the reserves. These data certainly validate the intensive efforts over the past several years which resulted in Crystallex securing the exclusive mining rights to this valuable deposit.'

'This is a deposit of impressive size,'said Ken Thomas, newly appointed Chief Operating Officer of Crystallex. 'I look forward to working with our Government partners in Venezuela to bring this important property into production. A significant amount of preparatory work has already been done,'Thomas added noting that, 'SNC-Lavalin is well underway with its work on the Feasibility Study for the development, construction and operation of a mining and processing facility.'

The resource and reserve estimates were calculated for two near contiguous deposits known as Conductora/Cuatro Muertos ('CO/CM') and Mesones/Sofia ('MS/SO'). Mineralization at CO/CM is contained within a moderately-dipping zone, 3 kilometres long and up to 400 metres thick. Mineralization is hosted by a shear zone characterized by foliation-parallel pyrite disseminations and crosscutting quartz-carbonate-pyrite-chalcopyrite veinlets. Alteration assemblages at CO/CM include biotite, epidote, carbonate, silica and tourmaline. The MS/SO deposits are predominantly tourmaline-bearing breccia pipes associated with intense silicification, potassium feldspar alteration, and coarse pyrite and chalcopyrite mineralization.

The resource estimates for the two deposits were made using geologic modeling and kriging techniques. The modeling took into account material types, grade domains, and geologic features. At a cutoff grade of 0.50 grams of gold per tonne, the resources for the Las Cristinas deposits are as follows:

LAS CRISTINAS RESOURCES

Deposit Measured Tonnes g/t Ounces Au

CO/CM 48,333,000 1.21 1,879,000 MS/SO 9,405,000 1.20 364,000 Total 57,738,000 1.21 2,243,000

Deposit Indicated Tonnes g/t Ounces Au

CO/CM 343,588,000 1.09 11,986,000 MS/SO 37,605,000 0.91 1,099,000 Total 381,193,000 1.07 13,085,000

Deposit Inferred Tonnes g/t Ounces Au

CO/CM 187,382,000 0.94 5,633,000 MS/SO 20,507,000 0.65 431,000 Total 207,889,000 0.91 6,064,000

Reserves were developed from Measured and Indicated resources by establishing the ultimate economic pit limits using Medsystem Lerchs-Grossman pit optimization software. The economic calculations were based on a gold price of US$325 per ounce and variable cutoff grades of about 0.50 grams of gold per tonne and higher, dependent upon material type. In-pit reserves, estimated in accordance with CIM Standards and National Instrument 43-101, are as follows:

LAS CRISTINAS RESERVES

Deposit Category Tonnes Grade Ounces Strip (Au g/t) Ratio

CO/CM Proven 34,133,000 1.43 1,569,000 1.30:1 Probable 167,955,000 1.31 7,073,000

MS Probable 21,860,000 1.28 900,000 1.89:1

Total Proven 34,133,000 1.43 1,569,000 1.34:1 Probable 189,815,000 1.31 7,973,000

Total Proven & Probable 223,948,000 1.33 9,542,000 1.34:1

The reserves are contained in two separate pits. The CO/CM pit will be the deeper of the two, at 300 metres below surface and with an overall strip ratio 1.34 to 1.

Mineralization at both CO/CM and MS/SO is open at depth. In addition, the pits include inferred resources that could not be categorized as reserves because of insufficient drill density. Thus, there is excellent potential for increasing resources, adding reserves, and decreasing the strip ratio, by undertaking additional drilling.

The reserve and resource estimates are based on a diamond drill data base of 98,100 metres in 894 holes and 116,525 assayed core intervals. During January and February of 2003, Crystallex, under the supervision of Dr. Luca M. Riccio, P. Geo., Crystallex's Vice President of Exploration and Gregory Maynard, P. Geo., on behalf of MDA, completed a verification program aimed at validating a previous operator's drill-core assays. The verification program included 2,188 metres of drilling in 11 holes that twinned holes completed by a previous operator and assaying of 1,089 core samples, 55 blanks, 110 checks and 110 standards. In addition, 262 pulps, 200 rejects and 342 quarter core samples from previous drilling were also re-analyzed. Assay results from the verification drilling and check sampling programs corroborate the general tenor of mineralization reported by the previous operator. All samples from the verification program were prepared at Triad Laboratory in Venezuela. Chemex Labs in Vancouver, Canada assayed 74 % of the samples. The remaining samples were assayed at Triad. The program was managed by qualified person Dr. Luca Riccio, P.Geo., with assistance during part of the program by qualified person Gregory Maynard, P.Geo., on behalf of MDA.

The persons responsible or involved in the resource and reserve estimations on behalf of MDA included Steven Ristorcelli, P. Geo., and Scott Hardy, P. Eng., both qualified persons for the purposes of National Instrument 43-101, with geologic input from Dr. Luca Riccio, P. Geo. An executive summary of this study will be filed on SEDAR (www.sedar.com) within 30 days of the issuance of this press release.

Future Development:

On February 12, 2003, Crystallex awarded to SNC-Lavalin Engineers & Constructors Inc. ('SNCL') the contract to undertake a Feasibility Study for the development, construction and operation of a mining and processing facility on its 100% controlled Las Cristinas project in Venezuela. The mandate to SNCL contemplates an initial 20,000 tonne per day operation capable of processing oxide and sulphide ores. The current schedule calls for the SNCL Feasibility Study to be completed this summer. In addition, SGS Lakefield Research Limited, Canada, have been contracted to run a metallurgical pilot plant to confirm the flowsheet for the Feasibility Study.

Domestic U.S. Oil producers like Sonoran Energy, Inc. are positioned to significantly benefit from rising demand for U.S. domestic oil production in light of the brewing International oil production crisis due to war, strikes, and terrorist threats. Just this week, the Nigerian subsidiaries of Royal Dutch/Shell Group (NYSE: RD) (NYSE: SC), ChevronTexaco Corp. (NYSE: CVX) and TotalFinaElf (NYSE: TOT) halted production totalling 817,500 barrels a day, or about 40% of Nigeria's output of some 2 million b/d amid violence between rival ethnic groups, the Ijaws and Itsekiri, leading up to April 19 parliamentary and presidential elections. Militant Ijaws reportedly threatened to blow up multinational oil installations they said they had captured in retaliation for government military raids.

Additionally, Oil-well firefighters from Houston-based Boots & Coots International Well Control (AMEX: WEL) are traveling to southern Iraq to assess damage in the country's key Rumaila oil fields. The firefighting teams are looking at a timetable of 30 to 45 days to extinguish the fires and cap the wells. But one source said the timing will depend on "what's all there." The Pentagon has contacted a number of major oil industry service companies - among them Halliburton Co. (NYSE: HAL) , once run by Vice President Dick Cheney -- to repair any of Iraq's wells that are damaged and assess everything from wells to pipelines and pumping stations.

Venezuela's oil industry collapsed in December, when employees at state-owned Petroleos de Venezuela walked off the job, angry about changes in the company under the administration of President Hugo Chavez. By the height of the strike, 16,000 employees had walked out, and production shrank to 200,000 barrels a day, costing Venezuela $6 billion. The country had to import fuel to keep vehicles moving, and drivers waited days at gas stations. The strike, which failed to oust Chavez or call early elections, was strongest in the oil sector, though businesses around the country shut down.
