Guinea: Siguiri Project

The Siguiri Permit acquired is located in south west of the prefecture of Siguiri, north east of Guinea, West Africa.

The permit has an area of 103 sq. km. and is located approximately 50 kilometers to Siguiri town (some 50,000 inhabitants) and 800 kilometers to the capital Conakry.

The permit is located on the northern rim of the Siguiri sedimentary basin. This region has been extensively explored over the past 50 years and most recently by Bassat and Dommanget (1986), Millesi and Al (1989) also the geologists of SAG Phil Davies and Smith in 1995.

The region is underlain by the fine grain sediments of lower proterozoic in age and compromise a sequence of intercolated grewackes, mudstones, shales, philites and sericite shistes that are generally steep dipping and strinking N-S to N-E. It is bounded to the north by Cambrian platform sediments, to the south by a late Archean shear belt and to the east by Eburnean granite.

Two dominant structural orientations are NNE and ENE, as evidence from air photo, land satellite and aeromagnetic interpretation. Quartz veining and late stage dolerite dykes predominate in the NW and ENE orientation.

The May 2006 exploration campaign conducted by Gold Coast's president and chief field geologist uncovered several interesting gold anomalous zones from the regional laterite rock chip sampling. It was recommended that an infill exploration program be undertaken to define the characteristics of the gold mineralization of the permit area.

 

Geology

The company commissioned geologist, Hendrik Veldhuyzen to complete a 43-101
( Competent Person’s ) report. The field work was completed at the end of 2006. His 2007 report classified the Siguiri concession as a "Property of Merit" warranting further exploration for both alluvial gravels and for hard rock vein systems.

The greenstone belt of Guniea have had a long history of placer gold mining and prospecting. These greenstone belts are considered to be the remnants of ancient sedimentary and volcanic rocks, which have been strongly metamorphosed. Similar greenstone belts sequences around the world (for example South Africa, Canada, Brazil, India, and Australia) are commonly mineralized with gold, silver and hematite iron ore. Major gold deposits in these worldwide greenstone belt sequences are common.
