Ayanfuri
Perseus holds 650sq km of tenements centred on the Ashanti Gold Belt. The 120sqkm Ayanfuri Project is situated 25-65km south west of the 60 million ounce Obuasi gold deposit.
Resource / Reserve Potential
Since acquiring an option over the Ayanfuri project in June 2006, Perseus increased gold resources from previously declared 200,000oz to 5.3Moz (indicated 3.15Moz; inferred 2.13Moz) by March 2009. The project has significant upside for further resource growth and the detailed feasibility for gold production at an initial rate of 200,000oz/annum is scheduled from completion in July 2009.
Setting
The Ayanfuri Mine Licences are underlain by Birimian metasediments and metavolcaniclastics which are intruded by intermediate granitoids. The adjoining Reconnaissance Licences cover a broader section of Ashanti belt lithologies including Birimian metasediments, metavolcaniclastics, volcanics and Tarkwaian epiclastics and intrusives.
Gold mineralisation at Ayanfuri occurs in quartz veins, stringers, stockworks and is disseminated in:
1. altered metagranodiorite intrusive bodies; and
2. typical "Ashanti" style shear zones within metavolcaniclastics.
The Ayanfuri gold mine produced over 300,000oz of gold from a shallow oxide heap leach operation which commenced in 1994. 23 shallow pits were mined, with most production from six granitoid intrusive orebodies ranging from 200m to 500m long and 30m to 120m wide.
