Factors that could cause future results or events to differ materially from current expectations expressed or implied by the forward-looking statements include the ability to meet our 2019- 2023 target annual production of 400,000+ ounces at $700/oz AISC, the ability to start production at the Mana underground in Q1 2020, the ability to meet our 2019-2023 target average production of 413,000 ounces at $714 AISC, the ability to generate over $1.2B of operating cash flow from 2019 to 2023 at $1,300 gold price, the ability to meet our 2019 guidance in terms of production, AISC, capital expenditure and non-recurring development expenditure, the ability of each of the Boungou Mine and the Mana Mine to meet its 5-year production and cost targets, the ability to complete the Nabanga deposit PEA by Q3 2019, the ability of the Mana Mine to meet its 2019-2025 LOM Plan and operational and financial objectives, the ability of the Boungou Mine to meet its 2019- 2026 LOM Plan and operational and financial objectives, the ability to meet Siou underground timeline, the ability to meet our 2019 exploration programs, the accuracy of our assumptions, fluctuation in the price of currencies, gold or operating costs, mining industry risks, uncertainty as to calculation of mineral reserves and resources, delays, political and social stability in Africa (including our ability to maintain or renew licenses and permits) and other risks described in SEMAFO’s documents filed with Canadian securities regulatory authorities.
