2. Forward Looking Statement
g
This presentation of Guyana Goldfields Inc. (the "Company") contains statements that constitute "forward-looking statements." Such forward-looking statements involve
known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements, or developments in our industry, to differ
materially from the anticipated results, performance or achievements expressed or implied by such forward-looking statements. Forward looking statements are statements
y p , p p p y g g
that are not historical facts and are generally, but not always, identified by the words "expects," "aims," "plans," "anticipates," "believes," "intends," "estimates," "projects,"
"potential" and similar expressions, or that events or conditions "will," "would," "may," "could" or "should" occur. Information inferred from the interpretation of drilling results
and information concerning mineral resource estimates may also be deemed to be forward looking statements, as such information constitutes a prediction of what might
be found to be present when and if a project is actually developed. Forward-looking statements this document includes are statements regarding: the Company's
expectations regarding drilling and exploration activities on properties in which the Company has an interest; and the Company's statements regarding estimates of
resources on properties in which the Company has an interest. There can be no assurance that such statements will prove to be accurate. Actual results and future events
could differ materially from those anticipated in such statements, and readers are cautioned not to place undue reliance on these forward-looking statements that speak
y p p g p
only as of their respective dates. Important factors that could cause actual results to differ materially from the Company's expectations include among others, risks related
to fluctuations in mineral prices; uncertainties related to raising sufficient financing to fund planned work in a timely manner and on acceptable terms; changes in planned
work resulting from weather, logistical, technical or other factors; the possibility that results of work will not fulfill expectations and realize the perceived potential of the
Company's properties; uncertainties involved in the estimation of resources; the possibility that required permits may not be obtained on a timely manner or at all; the
possibility that capital and operating costs may be higher than currently estimated and may preclude commercial development or render operations uneconomic; the
possibility that the estimated recovery rates may not be achieved; risk of accidents, equipment breakdowns and labour disputes or other unanticipated difficulties or
interruptions; the possibility of cost overrun or unanticipated expenses in the work program; the risk of environmental contamination or damage resulting from the
Company's operations; risks associated with title to mineral properties; and other risks and uncertainties discussed appear elsewhere in the Company's documents filed
from time to time with the Toronto Stock Exchange and Canadian securities regulators. These statements are based on a number of assumptions, including assumptions
regarding general market conditions, the availability of financing for proposed transactions and programs on reasonable terms, and the ability of outside service providers
to deliver services in a satisfactory and timely manner. Forward-looking statements are based on the beliefs, estimates and opinions of the Company's management on the
date the statements are made. Except as expressly required by applicable securities laws, the Corporation undertakes no obligation to update these forward-looking
statements in the event that management's beliefs, estimates or opinions, or other factors, should change.
This presentation uses the terms "Inferred Resource", "Indicated Resource" and "Mineral Resource". The Company advises readers that although these terms are
This presentation uses the terms Inferred Resource , Indicated Resource and Mineral Resource . The Company advises readers that although these terms are
recognized and required by Canadian securities regulations (under National Instrument 43-101 "Standards of Disclosure for Mineral Projects"), the US Securities and
Exchange Commission does not recognize these terms. Readers are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be
converted into reserves. In addition, "Inferred Resources" have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be
assumed that any part of an Indicated or Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral
Resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for a Preliminary Assessment as defined and permitted under National
Instrument 43-101. Readers are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable. The Mineral Resources
stated in this news release are not mineral reserves and, in the absence of a current feasibility study, do not demonstrate economic viability. The determination of mineral
2
, y y, y
reserves can be affected by various factors including environmental, permitting, legal, title, taxation, socio-political, and marketing issues.

fuchsite-sericite-carbonate alteration in tonalite intrusive probably emplaced at the hinge of the folded volcanic
rock and metasediments.
 Other zone’s mineralization: mesothermal gold veins hosted in the shear zones of metavolcanic and
metasedimentary rocks; occurs in a zone of pyrite-rich quartz-carbonate veins in volcanic rocks that are
enclosed in an alteration envelope which reportedly includes silica sericite and calcite cement filling fractures
