The different types of Archean gold deposits in the Manica greenstone belt of western Mozambique are briefely describcd in the context of their geological setting. Particular attention is devoted to the mineralogy, petrology, geological controls, refractoriness to treatment and prospection of these gold deposits. The genesis of gold was stratigraphically controled, but structural and metamorphic events related to the intrusion of late granites have concentrated and relocated the gold in different geological environments. The possibility of additional gold occurences in different rocks sequences is discussed as well as possible guidelines for future research and development.

In February 2015, when Econet Wireless Zimbabwe Limited, EWZL, the market leader of the telecommunications sector in Zimbabwe, published the financial results, the management team was worried about the shareholders’ reaction. With over 60% market share in its core business (the voice and SMS market), it has achieved remarkable results due to the great diversification strategy. However, the share price was continuously falling due to exogenous factors that were pressuring margins and threatening future sustainability of the company. EWZL was highly exposed to Zimbabwe’s specific risks and regulatory policies. This case explores both the business environment surrounding the company and the strategic decisions necessary to fight against the economic and political challenges. Students will step into Econet’s obstacles by analyzing the strategies and diagnosing the multiple risk factors affecting the profitability of the firm. Furthermore, they will have to compute the valuation of the firm, facing several challenges of a developing country.
