INVESTOR PRESENTATION November 14, 2017

Forward Looking Statements This presentation contains “ forward looking information ” or "forward looking statements" that involve a number of risks and uncertainties. Forward looking information and forward looking statements include, but are not limited to, statements with respect to the future prices of gold, copper and acid, toll rates, metals exposure and stockpile interest rate deductions, the estimation of mineral reserves and resources, the realization of mineral estimates, the timing and amount of estimated future production and output, costs of production, capital expenditures (including sustaining capex, non-discretionary capex and discretionary capex), costs and timing of the development of new deposits, potential benefits of the rotary furnace installation, success of exploration activities, permitting time lines, currency fluctuations, requirements for additional capital, government regulation of mining operations, environmental risks, unanticipated reclamation expenses, title disputes or claims, limitations on insurance coverage and timing and possible outcome of pending litigation. Often, but not always, forward looking statements can be identified by the use of words such as “ plans ” , “ expects ” , or “ does not expect ” , “ is expected ” , “ budget ” , “ scheduled ” , “ estimates ” , “ forecasts ” , “ intends ” , “ anticipates ” , or “ does not anticipate ” , or “ believes ” , or variations of such words and phrases or state that certain actions, events or results “ may ” , “ could ” , “ would ” , “ might ” or “ will ” be taken, occur or be achieved. Forward looking statements are based on the opinions and estimates of management as of the date such statements are made, and they involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any other future results, performance or achievements expressed or implied by the forward looking statements. Such factors include, among others: the actual results of current exploration activities; actual results of current reclamation activities; conclusions of economic evaluations; changes in project parameters as plans continue to be refined; future prices of gold, copper and acid; possible variations in ore grade or recovery rates; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining and smelting industries; delays in obtaining governmental approvals or financing or in the completion of development or construction activities, fluctuations in metal prices and toll rates, as well as those risk factors discussed or referred to in this presentation under and in the Company ’ s annual information form under the heading "Risk Factors" and other documents filed from time to time with the securities regulatory authorities in all provinces and territories of Canada and available at www.sedar.com. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be anticipated, estimated or intended. There can be no assurance that forward looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers are cautioned not to place undue reliance on forward looking statements. TSX:DPM 2
