CAUTIONARY NOTE REGARDING FORWARD-LOOKING INFORMATION: Certain statements contained on this website are forward-looking in nature and constitute “forward-looking information” within the meaning of applicable Canadian securities laws and “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 (collectively, “forward-looking information”). Generally, forward-looking information can be identified by the use of forward-looking terminology such as “plans”, “expects”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, “believes” or variations of such words and phrases (including negative or grammatical variations) or statements that certain actions, events or results “may”, “could”, “would”, “might” or “will be taken”, “occur” or “be achieved” or the negative connotation thereof. The forward-looking information involves risks and uncertainties including those relating to: Golden Star’s growth strategy; 2014 exploration and capital expenditure plans at Wassa and Bogoso; the estimation and establishment of mineral reserves and mineral resources; the recovery of any mineral reserves; 2014 gold production and production costs, as well as estimated recoveries; the targeted timing for the completion of a Preliminary Economic Assessment and Feasibility Study for, as well as for the mining of, Wassa underground; the source of ore feed to the Bogoso refractory plant; future permitting dates for additional sources of ore; and corporate responsibility goals and objectives. Forward-looking information is made based upon certain assumptions and other important factors that, if untrue, could cause the actual results, performance or achievements of Golden Star to be materially different from future results, performance or achievements expressed or implied by such information. Such information is based on numerous assumptions regarding present and future business strategies and the environment in which Golden Star will operate in the future, including the price of gold, anticipated costs and ability to achieve goals. Certain important factors that could cause actual results, performance or achievements to differ materially from those set forth in the forward-looking information include, among others, gold price volatility, discrepancies between actual and estimated production, mineral reserves and mineral resources and metallurgical recoveries, mining operational and development risks, litigation risks, regulatory restrictions (including environmental regulatory restrictions and liability), activities by governmental authorities (including changes in taxation), currency fluctuations, the speculative nature of gold exploration, the global economic climate, dilution, share price volatility, the availability of capital on reasonable terms or at all, local and community impacts and issues, results of pending or future feasibility studies, competition, loss of key employees, additional funding requirements and defective title to mineral claims or property. Although Golden Star has 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 as anticipated, estimated or intended. Please refer to a discussion of these and other risk factors in Golden Star's Annual Information Form for the year December 31, 2014 and dated March 21, 2014. The forward-looking information contained on this website constitutes management's current estimates with respect to the matters covered thereby. We expect that these estimates will change as new information is received and the actual results will vary from these estimates, possibly by material amounts. While we may elect to update these estimates at any time, we do not undertake to update any estimate at any particular time or in response to any particular event.
