A Review of the Birimian Supergroup- and Tarkwaian Group-Hosted Gold Deposits of Ghana

The vein- and sulphide-hosted gold is strongly a region with over 2,500 years of history with regards to associated with deformational fabrics formed by the gold production and trade. Modern exploration for and Eburnean extensional and compressional events, mining of gold in Ghana dates from 1874 with the respectively, suggesting that disseminated sulphide establishment of the British Gold Coast Colony, which mineralisation predates quartz vein-hosted was followed in 1957 by the independence of Ghana and mineralisation. The fluid from which the gold precipitated increased gold production since the early 1980s through is believed to have been of metamorphic origin and Ghana’s Economic Recovery Plan. At the time of writing, carbon dioxide (CO2) dominated, with lesser water (H2O) gold production (108.2 tonnes or 3.48 million ounces and nitrogen (N2) and minor methane (CH4). Gold [Moz] in 2014) accounted for approximately one-third precipitation was probably caused by decrease in of Ghana’s export revenues, with 36% of gold production pressure, temperature and CO2-H2O immiscibility, at coming from small-scale mining. -
The Geology of the Gold Deposits of Prestea Gold Belt of Ghana*
The Geology of the Gold Deposits of Prestea Gold Belt of Ghana* K. Dzigbodi-Adjimah and D. Nana Asamoah Dzigbodi-Adjimah, K. and Nana Asamoah, D., (2009), “The Geology of the Gold Deposits of Prestea Gold Belt of Ghana”, Ghana Mining Journal, Vol. 11, pp. 7 - 18. Abstract This paper presents the geology of the gold deposits along the Prestea gold belt of Ghana to assist exploration work for new orebodies along the belt. Prestea district is the third largest gold producer in West Africa after Obuasi and Tarkwa districts (over 250 metric tonnes Au during the last century). The gold deposits are structurally controlled and occur in a deep-seated fault or fissure zone that is regarded as the ore channel. This structure, which lies at the contact between metavolcanic and metasedimentary rocks in Birimian rocks, is more open (and contains more quartz lodes) at the southern end around Prestea than at Bogoso to the north. The gold deposits consist of the Quartz Vein Type, (QVT) and the Dis- seminated Sulphide Type (DST). The QVT orebodies, which generally carry higher Au grades, lie within a graphitic gouge in the fissure zones whilst the DST is found mostly in sheared or crushed rocks near the fissure zones. Deposits were grouped into three in terms of geographic location and state of development; The deposits south of Prestea are the least developed but have been extensively explored by Takoradi Gold Company. Those at Prestea have been worked exclusively as underground mines on QVT orebodies by Prestea Goldfields Limited and its forerunners; Ariston and Ghana Main Reef companies until 1998 whilst the deposits north of Prestea, which were first worked as surface mines (on DST orebodies) by Marlu Mines up to 1952, were revived by Billiton Bogoso Gold in 1990. -

Dedication To Abigail my beloved wife and our lovely children Abstract Decentralisation of government has been a major policy direction of the World Bank and International Monetary Fund (IMF) as an adjunct to the Structural Adjustment Programme (SAP) imposed on low income countries. Decentralisation is consistent with the neo-liberal policies of the Bank aimed at liberalising the economy and reducing the control of centralised bureaucracies. The emphasis in SAPs on the reduction of public spending has in many cases increased poverty. This has led to the growth of a new emphasis on decentralisation and participatory development to reduce poverty. The link between participation and local governance has become seen as an important means of improving the effectiveness of services and of empowering the poor to participate in the development processes that affect their lives. -

Name Signature Date ii Abstract Gold is an important resource located within the subsurface, and its mineralization is controlled by geology, structures and hydrothermal alteration within rock formations. The search for gold is therefore the search for structures within hydrothermally altered zones in the subsurface. For this reason two geophysical surveys namely airborne magnetic and radiometric, proven to be excellent in mapping structures, geology and hydrothermally altered zones were employed in the Birimian formation in the Eastern region of Ghana. The airborne magnetic and radiometric data obtained were processed into grids with Geosoft. Data enhancement filters such as reduction to the pole, vertical integral, analytical signal, first and second vertical derivatives and continuation filters were applied to the total magnetic intensity grid to enhance anomalies. -

While GHG emissions in Africa are relatively minimal in global dimensions, agriculture in the continent constitutes a major source of GHG emissions. In Ghana, agricultural emissions are accelerating, mainly due to ensuing deforestation of which smallholder cocoa farming is largely associated. The sector is also bedevilled by soil degradation, pests, diseases and poor yields coupled with poor agronomic practices. Climate Smart Agriculture (CSA) thus offers a way to reduce the sector’s GHG emissions and to adapt the sector to the adverse impacts of climate change. This study assesses the potential of CSA vis-à-vis conventional cocoa systems to enhance production, mitigate and/or remove GHG emissions and build resilience, in addition to understanding key determinants influencing CSA practices.
