Ayanfuri
The Ayanfuri Mine Licences are situated on the Ashanti Belt, 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 608,000 oz (indicated 268,000 oz; inferred 340,000 oz) to 3.9Moz (indicated 1,718,500 oz; inferred 2,211,800 oz) by April 2008. Drilling is ongoing and the Company has commenced a detailed feasibility study for a CIL mining operation.
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 shall 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.
