  • Adamus has been granted three Mineral Reconnaissance Licences in the Republic of Liberia covering an area of 3,107km2.
  • The Licences are located in a highly prospective Archaean belt north of the capital Monrovia in western Liberia.
  • The southernmost licence is adjacent to Africa Aura’s 1.5Moz Au resource at New Liberty.
  • Adamus has members of its management team with in-country experience and has engaged personnel who have previously worked with the Ministry of Lands, Mines and Energy Liberia


Adamus Resources Limited has been granted three Mineral Reconnaissance Licences in the Republic of Liberia. The licences cover an area of 3,107km2 within the highly prospective Archaean belts (Man Craton) in the western half of the country.

Liberia is primarily known for its iron ore deposits such as Arcelor Mittal’s 1Bt Yekepa deposit and African Aura’s 1.1Bt Putu deposit. BHP also holds four Exploration Licences for iron ore in Liberia. However, recent exploration successes by African Aura Mining at the New Liberty project (13Mt @ 3.8g/t, 1.5Moz Au) and by Hummingbird Resources at the Dugbe Project (21Mt @ 1.2g/t, 0.8M oz Au) has raised the profile of Liberia’s prospectivity for gold and led to a rapid increase in interest and activity.

Adamus’ three licence areas are located near the towns of Mambo, Bopolu and Fasama in western Liberia (Figure 2). These areas were selected based on several criteria :

  • Areas within the Archaean belts prospective for gold in the west of Liberia
  • Proximity to known hard rock gold deposits and occurrences (eg ; New Liberty deposit)
  • Proximity to alluvial gold workings
  • Proximity to a mixed unit of schist, amphibolite, and quartzite and iron formation that is prospective for gold

Figure 2 - Location Map

A US Geological Survey map of the Geological, Geophysical and Mineral Occurrences of Liberia was used to select licence areas. The map shows a close correlation between areas of alluvial gold workings and known hard rock mineralisation or a prospective schist-amphibolite unit. Adamus considers the alluvial gold workings to indicate the existence of a proximal hard rock source for the gold.

The Mambo Licence (Figure 4) covers an area of 580km2 and is located only a few kilometres south of African Aura’s New Liberty project and close to other advanced exploration prospects such as Weaju / Mano (0.84Moz Au). Aeromagnetic images reveal E-W trending magnetic features on Adamus’ licence that are very similar to those associated with the New Liberty deposit to the north. The western part of the licence covers alluvial workings that coincide with a segment of the prospective schist-amphibolite unit. No hard rock mineralisation is recorded but the alluvial gold is likely to be derived from a proximal hard rock source.

The Bopolu Licence (Figure 5) covers an area of 1,190km2 70km ENE of the New Liberty deposit and within the same Archaean belt. USGS geological mapping shows a unit of the prospective schist-amphibolite coincident with a large concentration of alluvial workings north of the town of Bopolu. The alluvial workings are located on an interpreted offset of the schist-amphibolite unit and although no hard rock source was mapped the alluvial working suggest a proximal source.

Figure 5 – Bopulu & Fasama Licences

The Fasama Licence (Figure 5) covers an area of 1,368km2 further to the northeast within the same Archaean belt as the Mambo and Bopolu licences. The USGS map shows a concentration of alluvial occurrences with associated hard rock workings at Henry’s Town to the southwest of Adamus’ licence.


About Liberia

Liberia is located in the West Africa gold province and borders the republics of Sierra Leone, Guinea and Cote d’Ivoire (Ivory Coast). It is the oldest independent republic in Africa (established in 1847) and is unique within Africa because of its long standing relationship with United States which has provided US$230 million under the bilateral aid assistance program during the 2010 FY. It has a hot equatorial climate.

The international community has been encouraged by Liberia’s return to democracy in 2005 which has been supported by the UN. Since the currently elected president, Ellen Johnson Sirleaf, took power in January 2006, Liberia has moved quickly towards rebuilding, economic growth and normalizing international relations with the rest of the world. The World Bank and the European Commission have agreed to contribute to Liberia’s infrastructure, reconstruction and education. The World Bank has agreed on a US$16.5 million grant for urgent infrastructure projects and the European Commission has given US$80 million for water and electricity projects as well as education. A further US$15 million threshold program has been signed with Millineum Challenge Corporation to strengthen indicators in land reform, female education and trade.

Liberia is described as one of the last underexplored regions in the world. The main mineral products are diamonds, gold and iron-ore with possible offshore deposits of crude oil. International mining companies operating in Liberia include BHP, Severstal Resources, ArcelorMittal and China investment conglomerate China Union. The country remains underexplored by modern means and has potential for hosting large deposits of gold, tin, iron ore and other minerals.
