The Tulu Kapi gold deposit was discovered and mined on a small scale by an Italian consortium in the 1930’s. Nyota Minerals Limited acquired the licences in 2009 and then undertook extensive exploration and drilling which culminated in an initial DFS in in December 2012 based on a 2.0Mtpa processing plant and capital expenditure totalling $290 million.
In December 2013, KEFI Minerals acquired 75% of Tulu Kapi for £4.5 million. This acquisition cost equates to only $10 per reserve ounce and provides the information collected from historical expenditure of more than $50 million.
In September 2014, KEFI acquired the remaining 25% of Tulu Kapi for £750,000 and 50 million shares.
The Ethiopian government became entitled to a 5% free-carry interest in Tulu Kapi upon granting of the Mining Licence in April 2015.
The Exploration Licences held by KEFI Minerals (Ethiopia) Limited cover an area of approximately 200 square kilometres over and near the Tulu Kapi deposit.
The altitude of the project area is between 1,600m and 1,765m above sea level. The climate is temperate with annual rainfall averaging about 150cm.
Tulu Kapi is located approximately 360km due west of Ethiopia’s capital, Addis Ababa. A main road to Addis Ababa is within 12km of Tulu Kapi and power lines on the main electricity grid are within 40km of the project.
The Tulu Kapi region has typical greenstone type geology which is characterized by prominent hills of intrusive rocks and deeply incised valleys containing metasediments and metavolcanic rocks.
Gold at the Tulu Kapi deposit is hosted in quartz-albite alteration zones as stacked sub-horizontal lenses in a syenite pluton into which a swarm of dolerite dykes and sills have been intruded. Gold mineralisation extends over a 1,500m by 400m zone and is open at depth (+400m).
The mineralisation is characterised by a simple mineralogy comprising gold, silver, pyrite and minor sphalerite and galena. Metallurgical recoveries of gold average more than 93% for oxide and sulphide ore in the planned open pit.
A technical paper detailing the history of Tulu Kapi exploration, discovery and geology is available in English and Italian, as well as being summarised in a presentation to the NewGenGold 2017 Conference.
