Forward - looking statements or information generally identified by the use of the words "believe", "will", "advancing", "strategy", "plans", "budget", "anticipated", "expected", "estimated", "target", "objective" and similar expressions and phrases or statements that certain actions, events or results "may", "could", "should", "will be taken" or "be achieved", or the negative connotation of such terms, are intended to identify forward - looking statements and information . Although the Company believes that the expectations reflected in such forward - looking statements and information are reasonable, undue reliance should not be placed on forward - looking statements since the Company can give no assurance that such expectations will prove to be correct . The Company has based these forward - looking statements and information on the Company's current expectations and projections about future events and these assumptions include : the economic viability of a project ; strategic plans, including the Company's plans with respect to its properties ; the amount of mineral reserves and mineral resources ; the amount of future production over any period ; the amount of waste tonnes mined ; the amount of mining and haulage costs ; cash operating costs per gold equivalent ounce produced ; cash operating costs per copper pound produced ; operating costs ; strip ratios and mining rates ; expected grades and ounces of metals and minerals ; expected processing recoveries ; expected time frames ; prices of metals and minerals ; mine life ; gold hedge programs ; the ability of the Company to successfully maintain operations at its producing assets, or to restart these operations efficiently or economically, or at all ; and the ability of the Company to continue as a going concern .
