Abstract

The 55 Zone is a uniquely high grade deposit that is currently being advanced through construction in the Hounde Greenstone belt in Burkina Faso. The indicated resource grades at 15.8 g/t and forms the basis for the current feasibility study which underpins the company’s current construction and development plans. First gold is scheduled to be poured at Yaramoko towards the end of the first half of next year with production averaging around 100,000 ounces per annum for the following eight years.
 
The 55 Zone deposit occurs within a brittly deformed, elongated, granitic body that has intruded the Hounde belt subparallel to the regional NNE foliation. During deformation brittle fracturing of the granite intrusion and subsequent thrusting of the hanging wall block allowed for the mobilization of fluids along the large regional shears into the 55 Zone structure where gold was able to precipitate. Gold mineralization occurs in two phases, a coarser free gold phase within quartz veining and a finer phase occurring as free gold or associated with fine pyrite. To date the deposit has been traced within this structure along a strike length of 800 metres and down to 900 metres vertically where it remains open along strike and down plunge.
 
The 55 Zone has many attributes that make it favourable to the process of underground mining, these same attributes confirm it as a bit of an outlier in terms of other deposits of this nature. As the project approaches 40% completion the Company eagerly anticipates crosscutting the ore body, later this year, and being able to start producing gold from this rare high grade ore body.


Ben Pullinger, Vice President, Exploration   Roxgold

Mr. Pullinger has over a decade of experience working in the resources sector. Before Roxgold, he was a research analyst at Toll Cross Securities Inc. Mr. Pullinger's experience ranges from underground mining in narrow vein deposits in northern Canada through to exploration primarily on shear zone hosted gold deposits in China and Ghana. Before Joining Toll Cross he worked as a Senior Project Geologist with Pelangio Exploration where he worked to advance Pelangio's projects in Ghana at Obuasi and Tepa culminating with discoveries at Pelangio's Manfo Project South of Ahafo.
