Crystallex Updates Shareholders on Venezuelan Exploration and Drilling Programs TORONTO, April 19 /PRNewswire-FirstCall/ -- Crystallex International Corporation (Amex: KRY; TSX:) announced today that exploration programs which include 13,500 meters of diamond drilling are currently under way at its Las Cristinas and La Victoria properties, both located in Bolivar State, Venezuela. The Las Cristinas program includes a first phase of infill drilling (4000 meters in 10 holes) aimed at converting inferred resources to indicated resources within the outline of the pit designed for a gold price of US$325 per ounce. A second phase of drilling (1800 meters in 6 holes) will evaluate large panels of inferred resources below the existing US$325 pit outline. Any changes to reserves resulting from the infill drilling programs are expected to be published by the end of the third quarter of 2004. Las Cristinas is one of the industry's largest undeveloped gold deposits with proven and probable reserves of 10.2 million ounces of gold (246 million tonnes @ 1.3 g/t Au at 0.5-0.7g/t Au cutoffs and a gold price of US$325) which are included in total measured and indicated resources of 15.3 million ounces of gold (439 million tonnes @ 1.1 g/t Au at 0.5 g/t Au cutoff). Inferred resources amount to a further 6.1 million ounces (208 million tonnes at 0.91 g/t). All reserve and resource estimates have been completed by Mine Development Associates of Reno, Nevada. The Las Cristinas deposit is a tabular, moderately dipping mineralized shear zone traceable for over 3 kilometers along strike. Anomalous gold values within the shear zone occur over widths up to 600 meters. The mineralized system is open at depth. The Company has recently awarded the EPCM contract for the Las Cristinas project to SNC-Lavalin Engineers & Constructors of Toronto, Canada and has submitted the final Las Cristinas Environmental Impact Statement for review and approval by the Ministry of Environment and Natural Resources ("MARN"). At the La Victoria deposit located in the El Callao gold district, Crystallex has initiated a 24 hole 7,500 meter infill drill program to evaluate the southern half of the deposit with the aim of upgrading previously identified inferred resources to indicated resources. Revised reserve estimates for La Victoria are expected to be completed by the end of the third quarter of 2004. Previous drilling in this sector of the deposit intersected high grade mineralization (e.g. 14.1 g/t Au over 20.5 m) pointing to the existence of a high-grade ore shoot with significant widths which is a principle target of the current infill drilling program. The La Victoria deposit is a moderately dipping auriferous shear zone which was mined by Crystallex between 2001 and 2003. The unoxidized portion of the deposit has a refractory component which does not yield satisfactory recoveries by conventional cyanide processing. Based on positive results from BIOX bench scale test work which indicates improvement in recoveries from approximately 60% to over 85%, Crystallex will conduct a pilot plant BIOX program during the second quarter at BIOMIN Technologies in South Africa. Crystallex expects to conclude the feasibility assessment of the BIOX process at La Victoria by the end of October, 2004. Drilling at Las Cristinas and La Victoria is being carried out by Major Drilling of Moncton, New Brunswick. Core samples, as well as standards, blanks and coarse rejects for quality control are delivered to SGS's preparation lab in Venezuela and subsequently analyzed by SGS' lab in Lakefield, Ontario. Dr. Luca Riccio, P.Geo, Crystallex's VP of Exploration, is the qualified person in charge of supervising the drilling programs. In addition to the aforementioned drilling programs, the Company will commence, in the second half of 2004, systematic exploration at its El Callao and Las Cristinas properties.

Cautionary Note to Investors - We use certain terms in this release, such as "resource," "measured resource", "indicated resource" and "inferred resource," that the SEC guidelines strictly prohibit us from including in our filings with the SEC. Furthermore, reserves have been calculated in accordance with NI 43-101, as required by Canadian securities regulatory authorities. For United States reporting purposes, however, a full feasibility study is required in order to classify mineral deposits as reserves, since the SEC permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. Therefore, the amount of reserves may differ for Canadian and US reporting purposes.
