Statements containing forward-looking information are not historical facts but instead represent management's expectations, estimates and projections regarding possible future events or circumstances. The forward-looking information included in this news release is based on management's opinions, estimates and assumptions in light of their experience and perception of historical trends, current conditions and expected future developments, management's assumptions regarding the Arrangement (including, but not limited to, Goldsource's ability to close the Arrangement on the terms contemplated, and to derive the anticipated benefits therefrom), as well as other factors that management currently believes are appropriate and reasonable in the circumstances. The forward-looking information contained in this news release is also based upon a number of assumptions, including Goldsource's ability to obtain court and regulatory approvals in a timely matter, if at all; its ability to satisfy the terms and conditions precedent of the Arrangement Agreement in order to consummate the Arrangement; assumptions in respect of current and future market conditions and the execution of Goldsource's and Mako's business strategies, that operations in Mako's and Goldsource's properties will continue without interruption, and the absence of any other factors that could cause actions, events or results to differ from those anticipated, estimated, intended or implied.

Such risks, uncertainties and other factors include, but are not limited to, failure to receive the required court, regulatory and other approvals necessary to effect the Arrangement; the potential for a third party to make a superior proposal; that Mako and its shareholders will not realize the anticipated benefits following the completion of the Arrangement; and those risks as further set forth in the Circular and filed on Goldsource's profile on the SEDAR+ website at www.sedarplus.ca.

Although Goldsource has attempted to identify important risk factors that could cause actual results or future events to differ materially from those contained in forward-looking information, there may be other risk factors not presently known to it or that it presently believes are not material that could also cause actual results or future events to differ materially from those expressed in such forward-looking information. 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, which speaks only as of the date made.
