The Company may, in some cases, use words such as "anticipate", "believe", "could", "estimate", "expect", "intend", "may", "plan", "predict", "project", "will", "would", and similar expressions that convey uncertainty of future events or outcomes to identify these forward-looking statements. Any statements contained herein that are not statements of historical facts may be deemed to be forward-looking statements. Forward-looking statements in this offering document include, but are not limited to, statements about: the Company's strategies and objectives, both generally and in respect of the Company's specific mineral properties; exploration plans and costs associated with the Illinois Creek Project; the completion of the Offering and Company's intended use of proceeds from the Offering; the timing of decisions regarding the strategy and costs of exploration programs with respect to, and the issuance of the necessary permits and authorizations required for, the Company's exploration programs; the timing and cost of the Company's planned exploration programs, and the timing of the receipt of results therefrom; the Company's future cash requirements; the Company's retention of all available funds and any future earnings; general business and economic conditions; the Company's ability to meet its financial obligations as they come due, including payments required to maintain the Company's mineral property interests; the timing and pricing of proposed financings, if applicable; the anticipated use of the proceeds from any financings completed by the Company; the potential for the expansion of the known mineralized zones at the Company's properties; and the potential for the amenability of mineralization to respond to proven technologies and methods for recovery of ore.

Although the Company believes that such statements are reasonable, the Company can give no assurance that such expectations will prove to be correct. Inherent in forward-looking statements are risks and uncertainties beyond the Company's ability to predict or control, including, but not limited to: the Company does not insure against all of the risks we face in the Company's operations; the Company's operations rely on adequate infrastructure and without reliable infrastructure, the Company's capital and operating costs may be affected; the occurrence of a significant event which disrupts the production of mineral resources at the Company's properties and the subsequent sale thereof for an extended period, could have a material negative impact on the Company's business, financial condition and results of operations; the Company's ability to acquire properties and develop mineral reserves in the future will depend on the Company's ability to develop its present properties and the Company's ability to select and acquire suitable producing properties or prospects for mineral exploration, of which there is a limited supply; the Company may experience an inability to attract or retain qualified personnel; the Company's mineral resources are only estimates and no assurance can be given that the anticipated tonnages and grades will be achieved, or that the indicated level of recovery will be realized; and the risk factors in the Company's other public filings available under the Company's SEDAR+ profile at www.sedarplus.ca.

Although the Company has attempted to identify important factors that could cause actual results to differ materially from those described in forward-looking statements, there may be other factors that could cause results not to be as anticipated, estimated or intended. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, believed, estimated or expected. The Company cautions readers not to place undue reliance on any such forward-looking statements, which speak only as of the date made. Except as required by law, the Company disclaims any obligation to revise or update any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events. The Company qualifies all of the forward-looking statements contained or incorporated by reference in this offering document by the foregoing cautionary statements.

The above noted allocation of capital and anticipated timing represents the Company's current intentions based upon its present plans and business condition, which could change in the future as its plans and business conditions evolve. Although the Company intends to spend the proceeds from the Offering as set forth above, there may be circumstances where, for sound business reasons, a reallocation of funds may be deemed prudent or necessary and may vary materially from that set forth above, as the amounts actually allocated and spent will depend on a number of factors, including the Company's ability to execute on its business plan. See the "Cautionary Statement Regarding Forward-Looking Information" section above.

The most recent interim financial report of the Company included a going-concern note. The Company is still in the exploration stage and the Company has not yet generated positive cash flows from its operating activities, which may cast doubt on the Company's ability to continue as a going concern. The Offering is intended to permit the Company to carry out its work program at the Illinois Creek Project and is not expected to affect the decision to include a going-concern note in the next annual financial statements of the Company.
