Petroleum exploration and production is the core of Equatorial Guinea's economy, and accounts for over 90% of Equatorial Guinea's national income. As a result, little attention has been given to exploring and making use of the country's mineral resources. There are no commercial mining operations in Equatorial Guinea. However, some artisanal alluvial gold workings are taking place. Modern exploration techniques in Equatorial Guinea have been non-existent and work that has been done has been preliminary, and carried out by foreign geological surveys. However, the country has been relatively well covered with respect to reconnaissance techniques such as stream sediment sampling. However, follow up studies on prospective gold (Coro) and tantalite/columbite (Aconibe) properties, resulted in poor sample size analyses which provided no quantitative information. The Ministry of Mines is now promoting the country's mining potential in hopes of attracting investors.

After independence, early investigations highlighted the potential for gold, base metals, bauxite and pegmatite minerals such as tin, tungsten and columbo-tantalite. Between 1981-1983 GEMSA (a Spain-Equatorial Guinea joint venture) prospected for gold, iron ore, ornamental stone, molybdenite, columbo-tantalite, bauxite and diamond opportunities.

Gold

Gold exploration and artisanal workings have identified three main areas - Coro, Aconibe and Mongomo on the northern margins of the Monts de Cristal terrane, as well as several other occurrences. These are small alluvial prospects currently yielding coarse gold, including several nuggets that occur with vein-quartz and lateritic minerals, attesting to nearby primary and secondary gold sources. The rivers of Rio Muni are worked by local artisans using simple panning and wooden sluice technologies. Historical records are incomplete, but at least 2.3t of gold was produced from the Coro area alone in the mid-70's.

In 2006, the United States Geological Survey reported that about 200 kg of gold were produced in Equatorial Guinea.

Diamond

Equatorial Guinea has had isolated reports of diamond occurrences, in particular the Nsork area in the south of the country. The adjacent Mitzic diamond region in Gabon contains reported diamond occurrences. Structural lineaments containing basic intrusives extend along strike from the Mitzic diamond occurrence into the Nsork area. Such structural lineaments are prime targets for the emplacement of kimberlitic pipes and dykes. This area’s heavy mineral sampling results have been negative, except for zinc-rich chromites. At Mitzic, such zinc-rich chromites are only found in close proximity to diamondiferous locations.

Indicators of diamond deposits in Gabon extend to the southern border of Rio Muni, and the Equatoguinean government believes surveys may show the potential for diamond deposits in southeastern Rio Muni.

Bauxite

Widespread lateritisation, and indications of high Al203, low Si02 bauxitic laterite with grades of 58.3% Al203, and Si02 in the range 2.1% to 5.3%, support the potential for bauxite particularly in the Nzanagavong and Akoakan areas.

Mineral Law & Legislation

The regulation of mining in Equatorial Guinea is handled by the Ministry of Mines, Industry, and Energy, which oversees activities in the mining and petroleum industries.

The government claims ownership of all mineral resources, and regulates them under law 9/2006 (replacing the former Mining Law, 9/1981).
