Semafo : Proximal Exploration on SEMAFO'S Natougou Returns Promising Results

MONTREAL, QUEBEC--(Marketwired - Jul 28, 2015) - SEMAFO (TSX:SMF)(OMX:SMF) today announced results from an ongoing 10,000 meter proximal drilling program at Natougou designed to explore the lateral extensions of the flat-lying Boungou Shear Zone (BSZ) proximal to the current in-pit resources. A new mineralized area, dubbed the Southwest Extension, has returned values of up to 10.29 g/t Au over 10 meters at depths varying from 8 to 131 meters. The target area measures approximately 200 meters wide and remains open towards the west and northwest.

Phase I of the 2015 reverse-circulation ("RC") proximal exploration was launched on July 1 with a program of 2,070 meters in 14 holes. The Phase I program had the objective of exploring previous 2015 drilling intersections in holes TPA0102, TPA0103, TPA0104, TPA0224, and TPA0226, which had returned interesting values of up to 10.82 g/t Au over 10 meters within a shear zone outside the resource pit shell (see Table 1). The 14-hole program was designed to provide a better understanding of the geometry of the shear zone while establishing the potential for proximal mineralization that could eventually be included in the resources base.

TABLE 1

As shown in Figure 1 and in Table 2 below, the shear zone is intersected by most holes. Results show that gold mineralization was obtained within a 200-meter wide corridor of the structure that seems to trend roughly northwest. The corridor remains open towards the northwest. At this stage, additional closer spaced drilling will be necessary to establish the relationship between the Southwest Extension and the main BSZ. The shear zone was not encountered in holes TPA0355 and TPA0376, possibly due to the presence of an intrusive body, and was not present in TPA0402 since the zone is interpreted to reach surface to the northwest.

TABLE 2

An additional 3,000-meter drill program is being planned to test the lateral continuity towards the west and the northwest in addition to reducing the spacing within the known mineralized area. In addition, the 10,000-meter proximal program will include follow-up exploration towards the east and north of the resource pit. A number of holes are also scheduled to explore the potential of the hangingwall structures previously identified by Orbis Gold in 2014.

For core drilling, all individual samples represent approximately one meter in length of core, which was sawn in half. Half of the core is kept on site for reference, and its counterpart is sent for preparation and gold assaying to the SGS Minerals Services laboratories of Ouagadougou, Burkina Faso. For RC drilling, all individual samples represent approximately one meter in length of rock chips homogenized and riffle-split to an approximately 2 kg subsample that is sent for preparation and gold assaying to the SGS Minerals Services laboratories of Ouagadougou. Each sample is fire-assayed for gold content on a 50-gram sub-sample. In addition to SGS's own QA/QC (Quality Assurance/Quality Control) program, an internal QA/QC program is in place throughout the sampling program, using blind duplicates, blanks and recognized industry standards.
