Guinea moves to transform its Artisanal and Small-Scale Gold Mining sector. Conakry, 17th April 2023 – The Guinean Government has taken an important step today, launching a $17-million project to reduce the use of mercury by the nation's artisanal gold miners. Used to extract gold from ore, mercury is a toxic chemical that can cause ...

Petroleum soon became the primary export, and the country's GDP increased dramatically in less than a decade; it continued to grow in the early 21st century. Deposits of gold, titanium, manganese, iron ore, and uranium exist but remain largely undeveloped.
In addition, it also possesses significant deposits of gold and diamonds. Gold is mined both industrially and artisanally; diamonds are extracted in only small quantities. But despite its abundance of minerals and energy, Guinea still ranks among the bottom ten states in the Human Development Index.
The mining sector offers significant opportunities and a solid legal framework for investment. Bauxite, iron ore, gold, and diamond mining represent key markets for Guinea and are …
The world's biggest mining project, a $20bn iron ore, rail and port development in a remote corner of west Africa, is expected to start this year after a 27-year wait beset by setbacks, scandals ...
Guinea's special forces on Sunday ousted the West African country's president, raising the political and operational risk for its minerals, which include bauxite, diamonds, iron ore and gold.
The Ladolam hydrothermal system, on Lihir Island, Papua New Guinea, hosts one of the youngest and largest gold deposits in the world. Several deep (more than 1 kilometer) geothermal wells were …
Open-pit Mining: Open-pit mining is a method used to extract gold from large, near-surface deposits. It involves the removal of overlying soil, rock, and vegetation to expose the gold-bearing ore. Once the ore is exposed, it is drilled, blasted, and transported to a processing plant for further extraction.
In this study, we summarise the geology, tectonic setting, hydrothermal alteration, and ore mineralogy of the primary gold mineralisation at Yatela with the objective of defining its link to the auriferous residuum, and thus form the basis of an ore genetic model for the deposit.
The Lero Project is located in the vicinity of Dinguiraye, a city in Guinea. Its existence was first uncovered in 1988, and since then, it has been operating as a surface mining project. The project officially commenced production in 1995. As of 1996, the mineral ore in the area was reported to be located in laterite, although specific details ...
The present work summarises the mode of occurrence of primary gold in the Tertiary gold deposits from the Rhodope massif extending between Greece and Bulgaria.
A fundamental distinction of gold-bearing ground regions is the classification of primary and secondary deposits. Primary deposits are described as earth with gold deposits, …
The soaring demand for electric vehicles is fueling dramatic changes in Guinea, home to the world's largest bauxite reserves.
Nimba iron ore project is a high-grade, direct shipping ore (DSO) deposit in south-east Guinea, Africa. It is one of the biggest undeveloped on or near-rail DSO projects in West Africa. The project is being developed by West Africa Exploration, a subsidiary of Sable Mining Africa (80%) and Nimba Mining (20%).
The mining sector accounts for 1.7% of the total MSME's in Papua New Guinea. The National Gold Bullion Policy will support the growth of the MSME in the non-renewable sector. The MSME Policy 2022 primary objective is to support, facilitate growth and development of MSME in all sector including mining.
The accurate determination of gold ore-formation age and ore-source isotope composition are of important significance in the research on gold geology and prospecting.
Bauxite is an important mineral in the mining industry. Globally, bauxite is the primary source of aluminum (Al) ore and a major industry in many countries including China, Australia, and Brazil. As such, grading Al concentration is of paramount interest in the mining process as is the need to determine concentrations of penalty elements. The …
Gold made up 34 percent of mining production in 2019. Guinea is also the 16th-largest exporter and the 13th-largest producer of diamonds. Furthermore, Guinea holds the …
Guinea has a high level of specialization in Aluminium Ore (1.47k), Gold (25), Coconuts, Brazil Nuts, and Cashews (21.9), Cocoa Beans (19.8), and Rubber (3.64). Specialization is measured using RCA, an index that takes the ratio between Guinea observed and expected exports in each product.
The Guinean state is in possession of both the largest reserves of bauxite and the largest connected iron ore deposit in the world, the latter of which has remained untouched until today. In addition, it also possesses …
Gold of low fineness (high silver content) is reprecipitated by reduction at the water table, as both gold and silver complexes destabilize under similar pH and Eh conditions. The identification of secondary enriched gold horizons, relative to primary ore, has important repercussions for the potential viability of a drilled deposit.
What are the potential benefits of increasing the taxation of a foreign extractive sector? This paper applies this question to the case of Guinea by using a multi-sector macro-inequality model with heterogeneous agents. We quantify the long-run equilibrium impact of additional taxation when the proceeds are invested in human …
Guinea moves to reduce mercury pollution from its artisanal gold mining sector. $17-million initiative will support access to markets, finance and the uptake of mercury-free gold …

I have been directly involved in pre-feasibility and feasibility studies for gold and gold–copper deposits, and I currently manage a team of resource modellers and ore deposit knowledge specialists.
The Lihir gold mine is located on the island of Lihir, in Papua New Guinea's (PNG) New Ireland Province, 700km north-east of Port Moresby.
Guinea - Mining, Agriculture, Oil: Guinea has from one-third to one-half of the world's known reserves of bauxite (the principal ore of aluminum), plus significant reserves of high-grade iron ore at Mount …
A mineral deposit forms because of a combination of complex geologic processes, and this makes it difficult to confirm effectively the presence of ore bodies below the surface. Primary haloes are commonly utilized in mineral exploration as an indicator of the presence of blind ore bodies. Three basic types of zoning occur in primary haloes of …
