The Company does not undertake to update the information contained or incorporated by reference in the short form prospectus, except as required by applicable securities laws. Forward-Looking Information The short form prospectus and the documents incorporated by reference therein contain "forward-looking information" within the meaning of applicable Canadian securities legislation. 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 in the short form prospectus and the documents incorporated by reference therein include, among other things, disclosure regarding: the Company's future outlook; the offering; the closing of the offering; the issuance of the securities pursuant to the offering; the information under the heading "Use of Proceeds" in the short form prospectus; the potential of the Company's current or future property interests; the future price of nickel and other minerals; the success of exploration and mining activities; the cost and timing of future exploration, production and development; the estimation of mineral resources and mineral reserves; the realization of mineral resource and mineral reserve estimates; the requirements for additional capital and other statements relating to the financial and business prospects of the Company. In addition, statements relating to mineral reserves or mineral resources are deemed to be forward-looking information, as they involve the implied assessment, based on certain estimates and assumptions, that the mineral resources and mineral reserves described can be profitably mined in the future. Forward-looking information is based on reasonable assumptions, estimates, analysis and opinions that have been made by management of the Company in light of its experience and its perception of trends, current conditions and expected developments, as well as other factors that management believes to be relevant and reasonable in the circumstances, as at the date of such information and is subject to known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of the Company to be materially different from those expressed or implied by such forward-looking information, including but not limited to: exploration and mining risks, the ownership by Teck Resources Limited of 42.5% of the Company's share capital; competition from competitors with greater capital; the Company's lack of experience with respect to development-stage mining operations; fluctuations in metal prices; uninsured risks; environmental and other regulatory requirements; exploration, mining and other licences; the Company's future payment obligations; potential disputes with respect to the Company's title to, and the area of, its mining concessions; the Company's dependence on its ability to obtain sufficient financing in the future; the Company's dependence on its relationships with third parties; the Company's joint ventures; the potential of currency fluctuations and political or economic instability in countries in which the Company operates; currency exchange fluctuations; the Company's ability to manage its growth effectively; the trading market for the Ordinary Shares; uncertainty with respect to the Company's plans to continue to develop its operations and new projects; the Company's dependence on key personnel; possible conflicts of interest of directors and officers of the Company; the legal and regulatory framework within which the Company operates, and those factors discussed in the sections entitled "Risk Factors" in the Company's annual information form and "Risks and Uncertainties" in the Company's interim management's discussion and analysis and in the Company's annual management's discussion and analysis which are incorporated by reference in the short form prospectus. Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such information. Accordingly, readers should not place undue reliance on forward-looking information. The Company does not undertake to update any forward-looking information contained in the short form prospectus or the documents incorporated by reference therein, except in accordance with applicable securities laws. Third Party Information The short form prospectus and this presentation include geographic and economic information, industry data and market share information obtained from independent industry publications, market research and analyst reports, surveys and other publicly available sources. Although the Company and Paradigm Capital Inc. (the "Agent"), believe these sources to be generally reliable, geographic and economic information, industry data and market share information is subject to interpretation and cannot be verified with complete certainty due to limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties inherent in any statistical survey. Accordingly, the accuracy and completeness of this data is not guaranteed. The Company and the Agent have not independently verified any of the data from third party sources referred to in the short form prospectus nor ascertained the underlying assumptions relied upon by such sources. Mineral Reserve and Resource Disclosure Due to the uncertainty that may be attached to inferred mineral resource estimates, it cannot be assumed that all or any part of an inferred mineral resource estimate will be upgraded to an indicated or measured mineral resource estimate as a result of continued exploration. Confidence in an inferred mineral resource estimate is insufficient to allow meaningful application of the technical and economic parameters to enable an evaluation of economic viability sufficient for public disclosure, except in certain limited circumstances set out in National Instrument 43-101-Standards of Disclosure for Mineral Projects. The economic analysis contained in the Company's technical report is based on probable mineral reserve estimates.
