Disclosure Statement
SPECIAL NOTE REGARDING FORWARD-LOOKING
STATEMENTS This slide presentation contains
forward-looking statements within the meaning of
the United States Private Securities Litigation
Reform Act of 1995 and applicable Canadian
securities laws, including statements relating
to the estimated reserves and resources at Las
Cristinas anticipated results of drilling
programs, feasibility studies or other analyses
the potential to increase reserves and expand
production, at Las Cristinas Crystallex's
projected construction and production schedule,
and cost and production estimates, for Las
Cristinas and management's statements regarding
its expectations regarding mining in Venezuela.
Forward-looking statements are based on estimates
and assumptions made by Crystallex in light of
its experience and perception of historical
trends, current conditions and expected future
developments, as well as other factors that
Crystallex believes are appropriate in the
circumstances. Many factors could cause
Crystallex's actual results, performance or
achievements to differ materially from those
expressed or implied by the forward looking
statements, including 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. These factors and
others that could affect Crystallex's
forward-looking statements are discussed in
greater detail in the section entitled "Risk
Factors" in Crystallexs Annual Information Form
(which is included in the Annual Report on Form
40-F that Crystallex files with the United States
Securities and Exchange Commission (the "SEC")
and elsewhere in documents filed from time to
time with the Canadian provincial securities
regulators, the SEC and other regulatory
authorities. These factors should be considered
carefully, and persons reviewing this press
release should not place undue reliance on
forward-looking statements. Crystallex has no
intention and undertakes no obligation to update
or revise any forward-looking statements in this
press release, except as required by law. NOTE
TO U.S. SHAREHOLDERS The terms "Proven Reserve"
and "Probable Reserve" used in this slide
presentation 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 SEC's Industry Guide 7.
The terms, "Measured Resource", "Indicated
Resource" and "Inferred Resource" used in this
press 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. While the terms "Measured Resource",
"Indicated Resource", and "Inferred Resource" are
recognized and required by Canadian regulations,
they are not defined terms under Industry Guide 7
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 Resource" and "Inferred 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
Resource" or "Inferred 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. For a detailed
discussion of resource and reserve estimates and
related matters see the Company's technical
reports, the Annual Information Form and other
reports filed by the Crystallex on www.sedar.com
and www.sec.gov. A qualified person has verified
the data contained in this presentation.
