WEST AFRICAN RESOURCES LIMITED ANNOUNCES A TECHNICAL REPORT FOR THE MANKARGA GOLD DEPOSIT IN BURKINA FASO

West African Resources Ltd. has released a technical report for its Mankarga gold deposit in Burkina Faso.

The Tanlouka gold project is located approximately 90 kilometres east-southeast of Ouagadougou, the capital of Burkina Faso, lying approximately 20 km south of Mogtedo, the nearest regional town. The project covers an aggregate area of 115 square kilometres, comprising one granted exploration licence.

West African Resources has a 90-per-cent interest in the Tanlouka property and has signed an agreement to acquire the remaining 10 per cent of the project from GMC SARL, following completion of a positive feasibility study, a Burkina Faso-registered entity.

Exploration history

The Mankarga 5 deposit was identified in 2000 by RAB Drilling following up anomalous rock chip and gold geochemistry anomalies that had been identified by surface sampling programs completed by previous worker Channel Resources Ltd. in the late 1990s. Since then, a number of reverse circulation and diamond drilling campaigns have been completed at the prospect by Channel and later West African Resources. By early 2014, a total of 60 RC holes (7,296.2 metres), 79 diamond holes (16,722.8 m) and 116 aircore (AC) holes (4,601 m) had been completed.

Geology and mineralization

The Tanlouka gold project occurs within the Manga-Sebba greenstone belt within a strongly arcuate volcanosedimentary northeast-trending belt in the central domain that is bounded to the east by the Tiebele-Dori-Markoye fault, one of the two major structures subdividing Burkina Faso into three lithotectonic domains.

The geology of the Tanlouka area is characterized by metasedimentary and volcanosedimenatry rocks, intruded by mafic, diorite and granodiorite intrusions. The sediments vary from a mafic to felsic composition. At the Mankarga 5 area, the metasedimentary pile is mostly composed of undifferentiated pelitic and psammitic metasediments, as well as volcanosedimentary units. Psammite (Sps) and pelite (Spc) are consistently laminated and occasionally schistose. The metasediments pile has been intruded by a granodiorite, which is occasionally porphyritic in texture, overprinted by shearing in places, and is generally parallel to subparallel with the main shear orientation.

The alteration mineralogy varies from chloritic to siliceous, albitic, calcitic and sericite-muscovite. The regional alteration is marked by chlorite, whereas sericite and silica are locally widespread in the sedimentary pile. Sericite/muscovite alteration is associated with weathering and also shears, with its intensity commonly decreasing with an increase in silicification overprint. Silicification appears shearbound, which is likely to be associated with gold mineralization. The metasediments are preferentially intensively silicified in close proximity to the granodiorite.

Observed gold mineralization at Mankarga 5 appears to be associated with mineralized shear-hosted quartz veins and veinlet arrays, silica, sulphide and carbonate-albite, and tourmaline-biotite alteration. Gold is free and is mainly associated with minor pyrite, chalcopyrite and arsenopyrite disseminations and stringers. The currently known mineralization extends along strike for approximately three kilometres, approximately 100 metres across strike and approximately 300 metres in elevation.

The Markoye fault is believed to be the main conduit for the gold mineralization found on Tanlouka. Mankarga 5 is considered to be a shear-zone-hosted-style disseminated sulphide gold deposit. Similar deposits are found in the late Proterozoic Birimian terranes of West Africa. These hydrothermal deposits are mostly late orogenic deposits and are associated with major shear zones.
