Semafo has reported the discovery of a new mineralized trend near its Samira Hill mine in Niger. The Tondé Boubangou Horizon (TBH) is located 20 km north of the Samira Hill processing plant and has been traced over a distance of 10 km along strike. Results to date have returned values of up to 1.48 g/mt gold across 43 m.
Semafo initiated exploration on the TBH in June 2011 following a compilation of historical early-stage exploration work in the area that revealed the presence of a 10-km-long geophysical trend associated with sporadic auger drilling geochemical anomalies. Historical work also included a few trenches and minimal reverse-circulation drilling, which had returned values of up to 1.3 g/mt gold over 7 m. Since June 2011, a total of 10,350 m of air core, 15,667 m of reverse-circulation, and 1,518 m of core drilling have been completed. As of mid-June 2012, results remained pending for 57% of the reverse-circulation and all of the core drilling.
Semafo’s current program for the TBH includes follow-up reverse-circulation drilling as well as core drilling along the more important zones of mineralization observed to date. Additional work will be performed based on the results of the ongoing program. (www.semafo.com)
