2222 Safe Harbour Statement Certain statements contained in this presentation constitute forward-looking statements. These statements relate to future events or the Corporation's future performance, business prospects or opportunities. All statements other than statements of historical fact may be forward-looking statements. Forward-looking statements are often, but not always, identified by the use of words such as "seek", "anticipate", "plan", "continue", "estimate", "expect, "may", "will", "project", "predict", "potential", "targeting", "intend", "could", "might", "should", "believe" and similar expressions. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements. The Corporation believes that the expectations reflected in those forward-looking statements are reasonable, but no assurance can be given that these expectations will prove to be correct and such forward-looking statements should not be unduly relied upon. These statements speak only as of the date specified. The Corporation does not intend, and does not assume any obligation, to update these forward-looking statements. These forward-looking statements involve risks and uncertainties relating to, among other things, results of exploration activities, the Corporation's limited experience with development-stage mining operations, uninsured risks, regulatory changes, defects in title, availability of materials and equipment, timeliness of government approvals, changes in commodity and particularly diamond prices, actual performance of facilities, equipment and processes relative to specifications and expectations and unanticipated environmental impacts on operations. Additional factors that could cause actual results to differ materially include, but are not limited to, the risk factors described in the Corporation’s Annual Information Form dated March 15, The Corporation cautions that the foregoing list of factors that may affect future results is not exhaustive. Actual results may differ materially from those expressed or implied by such forward-looking statements. The potential carats, rock value and gross value set out in this presentation are estimates which are calculated based on potential tonnage, average bulk sample grades and modeled carat values from the bulk sample. These figures are conceptual in nature and should not be unduly relied upon because they are based on preliminary exploration results and could be affected by the risks and uncertainties referred to above. There has been insufficient exploration to date to confirm such estimates for the Star or Orion Kimberlites or to define a mineral resource on the Star or Orion Kimberlites and it is uncertain if further exploration will result in the discovery of an economically viable mineral resource on the Star or Orion Kimberlites.
