Caution on Forward Looking Statements
Caution on Forward-Looking Information
‣ This presentation contains “forward-looking information”, within the meaning of applicable Canadian securities legislation and United States securities laws. Forwardlooking
information includes, but is not limited to, information with respect to the proposed business combination between Geoinformatics and Rimfire and matters relating
thereto as well as information with respect to exploration results, potential mineralization, mineral resources and future plans and objectives. Generally, forward-looking
information can be identified by the use of forward-looking terminology such as "plans", "expects", or "does not expect", "is expected", "budget", "scheduled", "estimates",
"forecasts", "intends", "anticipates", or "does not anticipate", or "believes" or variations of such words and phrases or statements that certain actions, events or results
"may", "could", "would", "might", or "will be taken", "occur", or "be achieved". Forward-looking information is based on the opinions and estimates of management at the
date the information is made, and is based on a number of assumptions and subject to a variety of risks and uncertainties and other factors that could cause actual events
or results to differ materially from those projected in the forward-looking information. Assumptions upon which such forward-looking information is based include, without
limitation, that the shareholders of Geoinformatics and Rimfire will approve the transaction, that all required third party, court, regulatory and governmental approvals to
the transaction will be obtained and all other conditions to completion of the transaction will be satisfied or waived. Many of these assumptions are based on factors and
events that are not within the control of Geoinformatics and Rimfire and there is no assurance they will prove to be correct. Factors that could cause actual results to vary
materially from results anticipated by such forward-looking information include changes in market conditions, variations in ore grade or recovery rates, risks relating to
international operations, the availability and costs of future financing, changes in metal prices and currency exchange rates, government regulation, dependence on key
personnel and employee relations, changes in project parameters, actual results of current exploration activities, the possibility of project cost overruns or unanticipated
costs and expenses, environmental risks, labour disputes and other risks of the mining industry, failure of plant, equipment or processes to operate as anticipated, the
business of the companies not being integrated successfully or such integration proving more difficult, time consuming or costly than expected as well as those risk factors
discussed in Geoinformatics‟ management discussion and analysis for the period ended March 31, 2009 and Rimfire‟s annual information form on Form 20-F for the year
ended January 31, 2009, available at www.sedar.com. Although Geoinformatics and Rimfire attempted to identify important factors that could cause actual actions, events
or results to differ materially from those described in forward-looking information, there may be other factors that cause actions, events or results not to be anticipated,
estimated or intended. There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially
from those anticipated in such information. Geoinformatics and Rimfire undertake no obligation to update forward-looking information if circumstances or management's
estimates or opinions should change except as required by applicable securities laws. The reader is cautioned not to place undue reliance on forward-looking information.
CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING ESTIMATES OF MEASURED, INDICATED AND INFERRED RESOURCES
‣ This presentation uses the terms “Measured”, “Indicated” and “Inferred” resources. United States investors are advised that while such terms are recognized and required
by Canadian regulations, the United States Securities and Exchange Commission does not recognize them. “Inferred Mineral Resources” have a great amount of
uncertainty as to their existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an 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 other economic studies. United
States investors are cautioned not to assume that all or any part of Measured or Indicated Mineral resources will ever be converted into Mineral Reserves.
United States investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or legally mineable.
