People have been mining for gold in Ghana for centuries. Long before European colonists set foot in the area in the 1400s, Ghanaians looked for gold with pickaxes, shovels, and pans. They washed or "panned" for gold along river banks or dug holes on the surface to find deposits of gold dust and nuggets.

The Project, undertaken by the Cardinal Namdini Gold Limited (CNML), a subsidiary of Shandong Gold Limited, a Chinese mining firm, is an open-cast (surface) gold mine and has an initial lifespan of 15 years. The area is a green field – the first in Ghana, since Newmont Akyem Company poured its first gold from a green field a 2013.
Mineralium Deposita, 2003. Two major epigenetic gold-forming events are recorded in the world-class gold province of southwest Ghana. A pre-Tarkwaian event was the source of the world-class Tarkwa palaeoplacers whereas post-Birimian and Tarkwaian deformation, which was related to the Eburnean orogeny, gave rise to the world-class (e.g. Prestea) to giant (e.g. Obuasi) …

ian Group, in which placer type gold deposits occur. Several major gold belts occur in the Brimian in Ghana. The Ashanti gold belt, which stretches for about 250 km from the coast in the northeasterly direction, is the most prominent. It bears such mesothermal gold deposits as the Ashanti, Prestea, Bogosu, and Konongo (Fig.1).
Although giant and supergiant gold ore deposits are extrememly rare, they are one of the most profitable targets in global gold exploration and research (e.g., Kerrich et al., 2000, Cooke et al., 2005, Leahy et al., 2005, Richards, 2013, Sanislav et al., 2015, Groves et al., 2016, Fougerouse et al., 2017, Goldfarb et al., 2017).Therefore, understanding how they are formed, …
The Ahafo gold district ( Fig. 1) in Ghana was chosen as a case study area for GIS-based MPM because it was once a prominent exploration field with over a half-century of exploration history ...
West Africa is particularly positioned to be a part of this industry as it is the location of four major gold deposits located in geologic shear-zones (Milési et al., 1991).In Ghana alone, these belts cover one-sixth of the country, which has allowed Ghana to produce 70% of sub-Saharan gold (Hilson, 2002) and become the 7th largest producer of gold worldwide (Authority …
Ghana is well endowed with substantial mineral resources, the major ones being gold, diamonds, manganese and bauxite. Gold is the predominant mineral produced in the country accounting for over 90% of all mineral revenues annually over the past two decades. The country is also endowed with unexploited deposits of iron
In Ghana, for example, the Paleoproterozoic Birimian sediment, considered to host most of the country's economically viable gold deposits (Manu et al., 2013), is mostly epigenetic gold quartz vein deposit types associated with deserminated sulphides (Dzigbodi-adjlmah, 1993).
Toronto Stock Exchange-listed PMI Ventures has announced that it has again intersected significant high gold grades (27 g/t Au over four metres) in the ongoing drill programme on its Fromenda ...
The Chirano Mine gold deposit is a typical example of a structurally controlled deposit developed along the Kumasi Basin and the Sefwi Belt margin structure. The area has undergone various regimes of structural deformations. Consequently, all the Chirano deposits are intimately associated with shears and faults along a single continuous structural corridor known …
Additionally, news articles by some online news portals also published articles on the newly found largest gold nugget in the history of Ghana. Image: Screenshot of video ... "Quartz is classically aligned with gold. Most hard rock deposits appear to occur in quartz, and gold-in-quartz has even taken on a life of its own."

Important deposits of this type are found in the USA, Africa, Western Australia, Ghana and Brazil. Epithermal Gold Deposits. Epithermal deposits also belong to the primary gold deposits. Here the gold lies fairly close to the surface in a depth of up to 1500 metres. This type of gold deposit is mostly found in sedimentary and magmatic rock.
Alluvial gold deposits in Ghana have over the years been mainly exploited by artisanal methods; however, the proliferation of mechanised methods in recent years has resulted in a significant increase in gold output (Rae et al. 2009; Buadee et al. 2018). The reason for the mechanisation is probably the result of Ghana's mining sector policy ...
