Certain information contained or incorporated by reference in this press release, including any information as to THEMAC’s future financial or operating performance, the likelihood and timing of commercial production, construction of plant, and obtaining required permits, statements with respect to the estimation of mineral resources and reserves, expanding mineral reserves and mineral resources, the realization of mineral reserve and mineral resource estimates, the timing and amount of estimated future production, capital costs, costs of production, metal or mineral recoveries, mine life and production rates, capital expenditures and success of mining operations, expected IRR and NPV constitute “forward-looking statements”. All statements, other than statements of historical fact, are forward-looking statements. The words “believe”, “expect”, “anticipate”, “contemplate”, “target”, “plan”, “intends”, “continue”, “budget”, “estimate”, “may”, “will”, “schedule” and similar expressions identify forward-looking statements. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by THEMAC, are inherently subject to significant business, economic and competitive uncertainties and contingencies. Such assumptions include the specific assumptions set out in this press release and in the Report, that future capital and operating costs will be in line with THEMAC’S assumptions, that mineral resource and mineral reserve estimates prove accurate, permits required to commence production will be obtained on a timely basis, copper, molybdenum, gold and silver prices will remain consistent with THEMAC’s expectations, that there are no changes in THEMAC’s development plans as new information is received, that THEMAC will be able to access financing, equipment and sufficient labor to carry out its planned business. Known and unknown factors could cause actual results to differ materially from those projected in the forward- looking statements. Such factors include, but are not limited to: fluctuations in the currency markets; fluctuations in the spot and forward price of copper, molybdenum, gold, and silver; volatility in the price of fuel and electricity; changes in national and local government legislation, taxation, controls, regulations and political or economic developments in Canada and the USA; business opportunities that may be pursued by THEMAC; operating or technical difficulties in connection with mining or development activities; employee relations; litigation; the speculative nature of exploration and development, including the risks of obtaining necessary licenses and permits; uncertainty surrounding the availability of water rights required for mining operations which, if not secured, could result in changes to the proposed plan for development of Copper Flat; contests over title to properties, particularly title to undeveloped properties; failure of processing and mining equipment to perform as expected; labor disputes; supply problems; uncertainty of production and cost estimates; the interpretation of drill results; the assumptions upon which the estimation of mineral resources and reserves prove inaccurate, which could lead to a restatement of reserves and resources;; changes in project parameters as plans continue to be refined; possible variations in ore reserves, grade of mineralization or recovery rates may differ from what is indicated and the difference may be material; legal and regulatory proceedings and community actions; accidents, title matters; regulatory restrictions; permitting and licensing; volatility of the market price of Common Shares; insurance; competition; and hedging activities. In addition, there are risks and hazards associated with the business of exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave - ins, flooding and the risk of inadequate insurance, or inability to obtain insurance, to cover these risks. Many of these uncertainties and contingencies can affect actual results and could cause actual results to differ materially from those expressed or implied in any forward-looking statements made by, or on behalf of, THEMAC. Readers are cautioned that forward-looking statements are not guarantees of future performance. All of the forward-looking statements made in this press release are qualified by these cautionary statements. THEMAC disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise, except to the extent required by applicable laws. “Operating cost per pound of copper”, “Life-of-mine sustaining capital”, “IRR” and similar terms are alternative performance measures. These performance measures are included because these statistics are key performance measures that management may use to monitor performance. Management may use these statistics in future to assess how THEMAC is performing to plan and to assess the overall effectiveness and efficiency of mining operations. These performance measures do not have a meaning within International Financial Reporting Standards (“IFRS”) and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.
