SEMAFO's Reserves and Measured and Indicated Resources Increase to 5.0 Million Ounces

Siou Reserves Up 27% Year over Year

MONTREAL, QUEBEC--(Marketwired - Feb. 19, 2015) - SEMAFO Inc. (TSX:SMF)(OMX:SMF) today announced its 2014 year-end mineral reserve and resource statement. As at December 31, 2014, total proven and probable mineral reserves were 2,240,300 ounces of gold. Measured and indicated resources totaled 2,756,900 ounces, representing a 13% increase over 2013. Reserves and measured and indicated resources increased to 5.0 million ounces of gold.


  • Mana total mineral reserves and resources increased by 250,000 ounces
  • Mana reserve grade augmented by 7% to 3.01 g/t Au
  • Siou's reserves stand at approximately 1.0 million ounces
  • Siou remains open at depth and laterally
  • Measured and indicated mineral resources increased by 13%

The changes in reserves are net of 2014 depletion due to production. All mineral resources reported are exclusive of mineral reserves. Reserves and resources were estimated using a gold price of $1,100 and $1,400 per ounce, respectively. All amounts are in US dollars unless otherwise stated.


At the end of 2014, Mana's mineral reserves totaled 23,144,000 tonnes at an average grade of 3.01 g/t Au for 2,240,300 ounces, compared to 25,516,100 tonnes at an average grade of 2.81 g/t Au for 2,302,500 ounces the year prior. The slight decline in reserves is mainly due to a revision of the geological interpretation of Wona-Kona, more specifically in the Wona North pit.


Due to 25,000 meters of definition drilling completed below 180 meters vertically to convert a portion of resources into reserves, Siou's proven and probable reserves increased by 27% to 980,000 ounces by year-end 2014, net of 97,200 ounces from mined depletion in the year. Measured and indicated resources at Siou totalled 2,800,000 tonnes at 2.22 g/t Au for 199,500 ounces, an increase of 28% compared to 2013.


As a result of recent definition drilling, the Fofina deposit attained 2,443,200 tonnes at an average grade of 2.62 g/t Au for a total of 205,700 ounces in proven and probable reserves as at December 31, 2014, net of 88,100 ounces from mined depletion in 2014.


At the end of 2014, Wona-Kona reserves stood at 13,275,500 tonnes at a grade of 2.27 g/t Au for 970,100 ounces, representing a 3% increase in grade. Measured and indicated resources at Wona-Kona increased by 13% to 1,787,000 ounces.

SEMAFO's 2015 initial exploration budget has been established at $18 million, and activities are expected to involve up to eight auger rigs and four RC rigs for 310,000 meters of auger and 105,000 meters of reverse-circulation drilling. A $6 million provision has been made for pursuing exploration activities on the Banfora property, which now totals 1,600 square kilometers over 15 permits.

The mineral reserves and resources were estimated as at December 31, 2014 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 Mana 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, who has reviewed this press release for accuracy and compliance.
