Crystallex Announces CVG Approval of Las Cristinas Feasibility Study Company now anticipates the construction phase of the project TORONTO, March 8 /PRNewswire/ -- Crystallex International Corporation (Amex: KRY; TSX) announced today the approval bythe Corporacion Venezolana de Guayana ("CVG") of Crystallex's full Feasibility Study for the development of the Las Cristinas mining properties in Bolivar State, Venezuela. On September 17, 2002, Crystallex entered into a mining operation agreement with the CVG which granted to Crystallex the exclusive right to fully develop and exploit the significant gold reserves and resources at Las Cristinas. Mine Development Associates of Reno, Nevada, estimated in the Feasibility Study that proven and probable reserves amounted to approximately 10.2 million ounces (246 million tonnes at 1.29 g/t) based on measured and indicated resources of some 15.3 million ounces (439 million tonnes at 1.09 g/t) inclusive of the 10.2 million ounces of reserves, while inferred resources were estimated at approximately 6.1 million ounces (208 million tonnes @ 0.91 g/t). The full Feasibility Study, prepared by SNC-Lavalin Engineers & Constructors, was delivered to the CVG on September 10, 2003 by Crystallex, and since thattime, Crystallex has worked closely with the CVG to obtain final approval. The Feasibility Study addresses and confirms the economic and technical viability of the Las Cristinas Project and provides the foundation for construction and operating plans. "The approval by the CVG is a major milestone in the development of the Las Cristinas properties," said Todd Bruce, President and CEO of Crystallex. "We expect that the formal granting of our Engineering, Procurement and Construction Management ("EPCM") contract for Cristinas will very quickly follow the CVG approval. Our Chief Operating Officer, Dr. Ken Thomas, and his team have been working with EPCM candidates for several months in anticipation of this approval to ensure that we proceed as quicklyas possible." Mr. Bruce also acknowledged the dedicated efforts of CVG representatives in finalizing the approval. "We enjoy an excellent working relationship with our partner, the CVG, and this relationship will stand us in good stead as we proceed through the permitting and construction stages of the project. We look forward to bringing long awaited investment and employment opportunities to the people of Bolivar State and Venezuela. I would like to especially acknowledge the leadership of General Francisco Rangel Gomez throughout the entire process and thank John Madero, Vice President of Mining, and the CVG senior staff for their professionalism, support and guidance during this critical period." General Rangel Gomez confirmed the approval andcommented: "The CVG is very pleased to announce the approval of the Crystallex Feasibility Study for the Las Cristinas Project. We look forward with great anticipation to the start of gold production in early 2006 and all of the associated benefits that will be generated for the local community, Bolivar State and the Republic through the jobs created, social benefits and royalties and taxes paid to the CVG and the Republic." The Feasibility Study clearly distinguishes Las Cristinas as a premier gold deposit that can be economically developed and operated by conventional mining and gold processing technology. The reserves delineated by the Feasibility Study transform Crystallex into the fifth largest North American based gold company in terms of reserves. Highlights of the approved Feasibility Study include: * Proven & Probable Reserves: 246 million tonnes at 1.29 g/t (10.2 million ounces) using a gold price of US$325/oz * Measured & Indicated Resources including reserves: 439 million tonnes at 1.09 g/t (15.3 million ounces) * Additional Inferred Resources: 208 million tonnes @ 0.91 g/t (6.1 million ounces) * Low Strip Ratio of 1.34:1 (Less than 1:1 in the first five years) * Expected metallurgical recovery of 89% * Deposit open at depth * Other mineralized zones not yet drilled Reserves and Resources calculated in accordance with Canadian NI 43-101 Dr. Thomas added: "Once we have awarded the EPCM contract, Crystallex intends to move forward quickly to get final approval for our Environmental Impact Study ("EIS") report and, in conjunction with the CVG, to secure the Land Use Permit and the Permit to Impact the Environment. The Company has also initiated an internal study to investigate higher mining rate alternatives and possible expansion scenarios to the 20,000 tonnes per day operation outlined in the Feasibility Study. Crystallex will also shortly begin a drill program to test other mineralized zones within the Las Cristinas properties, including the zone below the US$325 gold pit shell as described in the Feasibility Study. The intention of the latter program is for in-fill drilling to increase the density of drilling in this area in order to upgrade current inferred resources into measured and indicated resources which in turn can be converted into proven and probable reserves." Dr. Thomas further confirmed that Crystallex had completed and exceeded its contractual obligations to advance social programs with new water treatment facilities, sewerage systems, medical clinic expansions, housing and road improvements having been provided for the local community.
