Crystallex Reports Grade Results From Las Cristinas 2005 Infill Drill Program TORONTO, June 22 /PRNewswire-FirstCall/ -- Crystallex International Corporation (AMEX:KRY) Toronto today reported the assay results for the follow up Las Cristinas infill drilling program comprising 5,551 meters in 14 holes that was initiated in January 2005. Crystallex implemented this program to upgrade inferred resources to proven and probable reserves at Las Cristinas in order to update the current reserves. Results for all the principal mineralized intervals of the infill drilling program are tabulated below and the location of the collar positions are shown in Figure 1. (Photo: http://www.newscom.com/cgi-bin/prnh/20050622/CLW022 ) The purposes of the infill drill program were: - to confirm the continuity and grade of the westward-dipping ore body in the western and southern parts of the modeled Conductora - Cuatro Muertos pit shell; - to increase the level of confidence regarding the distribution and grade of the ore body to the extent that inferred resources could be upgraded to indicated resources; - to incorporate the newly defined indicated resources into a revised Las Cristinas resource and reserve model to be completed by Mine Development Associates ("MDA") of Reno, Nevada for release by Crystallex in early July 2005. Todd Bruce, Crystallex President and CEO, commented, "These results again show the remarkable continuity of the ore bodies and consistency in grade of the mineralized zones in the Conductora - Cuatro Muertos area. The drill program confirms the presence of a SW-striking, high grade core zone in the southern part of the Conductora area. We are presently updating all of our current data and analysis in respect of the Las Cristinas deposit and expect that the updated reserve calculations incorporating these drill results, currently being prepared by Mine Development & Associates ("MDA"), should be released in the first part of July."

All bore holes were inclined due east at angles that range from 65 to 78 degrees from the horizontal. Assays were conducted on 1/2 NQ core sampled at continuous 1 meter intervals. In-house standards were inserted every 20 samples, and assay blanks every 50 samples. Duplicate assays were carried out, on average, on every 12th sample. Core samples as well as standards, blanks and coarse rejects for quality control, were prepared at Societe Generale de Surveillance's ("SGS") sample preparation laboratory in Tumeremo, Venezuela, and subsequently assayed at SGS's analytical laboratory in Lakefield, Ontario.

NOTE: This Release may contain forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, which involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Crystallex, or industry results, to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Forward- looking statements are subject to a variety of risks and uncertainties, which could cause actual events, or results to differ from those reflected in the forward-looking statements. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward looking statements. Specific reference is made to "Narrative Description of the Business - Risk Factors" in the Company's Annual Information Form ("AIF"). Forward-looking statements in this release including, without limitation to, statements regarding the expectations and beliefs of management include the following: gold price volatility; impact of any hedging activities, including margin limits and margin calls; discrepancies between actual and estimated production, between actual and estimated reserves, and between actual and estimated metallurgical recoveries; mining operational risk; regulatory restrictions, including environmental regulatory restrictions and liability; risks of sovereign investment; speculative nature of gold exploration; dilution; competition; loss of key employees; additional funding requirements; and defective title to mineral claims or property, as well as those factors discussed in the section entitled "Risk Factors" in Crystallex's AIF, annual report, and elsewhere in documents filed from time to time with the Canadian provincial securities regulators, the United States Securities and Exchange Commission ("SEC"), and other regulatory authorities. ADDITIONALLY: The terms "Mineral Reserve," "Proven Mineral Reserve" and "Probable Mineral Reserve" used in this release are Canadian mining terms as defined in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects under the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council on August 20, 2000 as may be amended from time to time by the CIM. These definitions differ from the definitions in the United States Securities & Exchange Commission ("SEC") Guide 7. In the United States, a mineral reserve is defined as a part of a mineral deposit which could be economically and legally extracted or produced at the time the mineral reserve determination is made. The terms "Mineral Resource," "Measured Mineral Resource," "Indicated Mineral Resource," "Inferred Mineral Resource" used in this release are Canadian mining terms as defined in accordance with National Instruction 43- 101 - Standards of Disclosure for Mineral Projects under the guidelines set out in the CIM Standards. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. For a detailed discussion of resource and reserve estimates and related matters see the Company's technical reports, including the Annual Information Form and other reports filed by the Crystallex on http://www.sedar.com/. A qualified person has verified the data contained in this release. Note to U.S. Investors: While the terms "mineral resource," "measured mineral resource," "indicated mineral resource," and "inferred mineral resource" are recognized and required by Canadian regulations, they are not defined terms under standards in the United States and normally are not permitted to be used in reports and registration statements filed with the SEC. As such, information contained in this report concerning descriptions of mineralization and resources under Canadian standards may not be comparable to similar information made public by U.S. companies in SEC filings. With respect to "indicated mineral resource" and "inferred mineral resource" there is a great amount of uncertainty as to their existence and a great uncertainty as to their economic and legal feasibility. It can not be assumed that all or any part of an "indicated mineral resource" or "inferred mineral resource" will ever be upgraded to a higher category. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. The Toronto Stock Exchange has not reviewed this release and does not accept responsibility for the adequacy or accuracy of this news release. http://www.newscom.com/cgi-bin/prnh/20050622/CLW022 http://photoarchive.ap.org/ DATASOURCE: Crystallex International Corporation CONTACT: Investor Relations, A.
