TOUR OUTLINE

The Australian Mineral Foundation continued its International Study Tour series of courses by providing a unique opportunity to:

Visit nine major gold deposits across Africa, from the Indian Ocean to the Atlantic - and to study at first hand the topical & exciting new projects, and the rejuvenated established gold fields of these two parts of the continent that have attracted so much interest over recent years.

See the most important examples of a diverse range of gold deposit styles, settings and districts - to learn more about African gold exploration potential, and to apply the lessons back home. Deposits visited included examples in both Archaean and Proterozoic greenstone belts in East and West Africa respectively, both transgressive hydrothermal systems and conformable blanket like orebodies in Proterozoic conglomerates, granite & greywacke hosted deposits adjacent to Proterozoic greenstone belts, and major lateritic gold accumulations.

The nine mines and projects on the itinerary included the following:

MODULE 1 - EAST AFRICA

• Overview Briefings - at the mines visited
• Golden Pride - a mine operated by Resolute Ltd in Tanzania
• Bulyanhulu - a new mine under construction at the time of the visit for Barrick Gold in Tanzania
• Geita - a joint venture between Ashanti Goldfields and AngloGold in Tanzania

MODULE 2 - WEST AFRICA

• Overview Workshops - in Accra and Bamako
• Damang - in Ghana, and operated by Ranger Minerals.
• Tarkwa - a rejuvenated established operation mined by Gold Fields Ltd in Ghana.
• Obuasi - the premier gold mine of Ghana, owned by Ashanti Goldfields.
• Yamfo-Sefwi - a new discovery in Ghana under investigation by Normandy LaSource.
• Sadiola - a major mine in western Mali, operated by AngloGold.
• Morila - a new development in southern Mali - a joint venture between Randgold and AngloGold.

In addition to the mine visits, there were high level workshops to provide an overview of the regional tectonic, geological and metallogenic setting of the districts and deposits visited, plus information pertinent to exploration and field reconnaissances.

The primary focus of the tour was geological, although attention was also  devoted to the mining, metallurgical and economic aspects of each operation.

Tour participants were from around the world. They brought a breadth of knowledge and international experience that  broadened and enriched the discussion and greatly enhanced the tour as the group travelled together and viewed the deposits visited from their varying perspectives and backgrounds.

All of the arrangements were made by PGC to allow  the maximum impact, in the minimum time, and at reduced costs.
