SEMAFO: Positive Mana PFS and Reserve Additions at Mana and Boungou

5-Year Average Target of 413,000 Ounces of Annual Production, AISC $696

MONTREAL, Quebec, Feb. 15, 2018 (GLOBE NEWSWIRE) --

SEMAFO Inc. (TSX:SMF) (OMX:SMF) today announced positive pre-feasibility study (PFS) results at Mana, the addition of 188,000 ounces of reserves, primarily at Siou underground, and an increase of 203,000 ounces of reserves at Boungou. As a result, the Corporation is providing the following consolidated five-year operational targets.

(1)  Mana results are based on the Mana PFS by Micon International Ltd.,   
     presented in Appendix 3.                                              
(2)  Boungou results are based on the updated mine plan presented in       
     Appendix 4.                                                            
(3)  Assumption: Mineral reserves were estimated using a Gold price of     
     $1,200/ oz.                                                           
(4)  All-in sustaining cost is a non-IFRS financial performance measure with
     no standard definition under IFRS and represents the total cash cost, 
     plus sustainable capital expenditures and stripping costs per ounce.  
(5)  The Mana AISC in the PFS has been updated for this analysis. The costs
     in the PFS are comparable to current costs except for the US/Euro     
     exchange rate, which has fallen approx. 10%. Roughly 75% of the AISC is
     based on CFA, which is linked to the Euro. The AISC has therefore been
     increased by 10% for the 75% of the cost base.                        

Highlights of Mana Pre-feasibility Study

--  Siou underground reserves stand at 3,035,000 tonnes at 5.29 g/t Au for
    515,800 ounces
--  Siou open-pit reserves stand at 1,579,000 tonnes at 3.57 g/t Au for
    181,200 ounces
--  Mana added 188,000 ounces of reserves before depletion, mainly from Siou
    underground
--  Mana annual production will average over 200,000 ounces between 2019 and
    2023 at an all-in sustaining cost of $810 per ounce at a gold price of
    $1,200
--  Pre-production capital expenditure of $51.7 million, to be financed with
    existing cash
--  Underground operations eliminate the need to mine 62 million tonnes of
    open pit waste
--  Mineral reserves at Mana stand at 18.2 million tonnes at a grade of 2.92
    g/t Au for 1,710,300 ounces at year-end 2017 based on a gold price of
    $1,200 per ounce
   

Mana Pre-feasibility Study

The Mana PFS provides a revised mine plan for all of Mana, including the Wona-Kona open pit, Siou open pit and Siou underground (see Appendix 3). An updated mineral reserves and resources statement for Mana is provided in Appendix 1.
The PFS investigated the potential for extracting the deeper zone of the Siou deposit using underground mining operations, mainly long-hole stoping. Access to the operations will be through a single portal and a 5.5- by 5.5-meter ramp at a 14-gradient slope. The location of the portal will allow mining in the northern part of the Siou pit to continue uninterrupted. The ultimate size of the underground mining operation will be more than 600 meters along strike by 200 meters deep. Figure 1 illustrates the underground mining layout for the Siou mine.

The PFS is based on a 2,000-tpd operation using contractor mining with discussions already ongoing with potential contractors. The underground mining costs are estimated at $70 per tonne milled. The 18-month development period is expected to begin in the third quarter of 2018.

Table 2 provides an overview of the major milestones for development of Siou underground.

The mineral reserves and resources were estimated as at December 31, 2017 in accordance with the definitions adopted by the Canadian Institute of Mining Metallurgy and Petroleum and incorporated into National Instrument 43-101 - Standards of Disclosure for Mineral Projects (NI 43-101).

The PFS for the Mana Mine was carried out by an in-house team whose work was reviewed by qualified persons from Micon International Ltd. Micon International Ltd. has reviewed this press release for accuracy and compliance with NI 43-101. Further details will be presented in a NI 43-101 compliant report to be filed on SEDAR within 45 days of the date of this press release.

Boungou Reserves & Resources Update

The 2017 infill drill program at Boungou added 203,000 ounces of reserves and 201,000 ounces of measured and indicated resources. The additional reserves have been pit-constrained at a $1,200 gold price and are included in the updated reserves and resources statement in Appendix 2. As at December 31, 2017, mineral reserves at Boungou stood at 11.2 million tonnes at 4.11 g/t Au for 1.5 million ounces of gold. The additional reserves support an average production profile of over 200,000 ounces per year between 2019 and 2023 at an average AISC of $516 per ounce. The updated Boungou mine plan is presented in Appendix 4.

An internal trade-off study was conducted on the West Flank in order to determine whether open pit or underground was the optimal mining approach. Open-pit mining provided better returns compared to an underground mining method. The remaining underground resources are included in the measured and indicated category, but are not included in the mine plan. Given the open-pit option, no pre-feasibility study is necessary.

The mineral reserves and resources were estimated as at December 31, 2017 in accordance with the definitions adopted by the Canadian Institute of Mining Metallurgy and Petroleum and incorporated into National Instrument 43-101 - Standards of Disclosure for Mineral Projects (NI 43-101). Mineral reserves and resources estimates for the Boungou Mine were carried out by an in-house team under the direction of Michel Crevier P.Geo MScA, Vice-President, Exploration and Mine Geology and SEMAFO's Qualified Person.

Conference Call

(1)  Cash operating cost per tonne is a non-IFRS financial performance     
     measure with no standard definition under IFRS and is calculated using
     total operating costs related to tonnes processed (which includes     
     capitalized stripping activities) over tonnes processed.              
(2)  All-in sustaining cost is a non-IFRS financial performance measure with
     no standard definition under IFRS and represents the total mining     
     operation expenses (which includes capitalized stripping activities), 
     plus sustainable capital expenditures.
