Cote d’Ivoire

Today Cote d’Ivoire is among the fastest growing economies in the world, and one of the most dynamic in West Africa. Côte d’Ivoire introduced a progressive new mining code in 2014, and on-going infrastructure improvements are making the country one of the more investor friendly countries in Africa. There is a strong desire to diversify the economy with gold and other mineral products. Exporting electricity  is playing an increasing role in this diversification.  Last year Côte d’Ivoire produced around 25 tonnes of gold up from only 1.2 tonnes in 2007. The mining sectors turnover rose by 11.5% in 2017, an increase achieved mainly via exports of gold, manganese and nickel. The country has 5 major producing gold mines and a number of near term development projects including Ity and Agbou (Endeavour), Yaoure and Sissingue (Perseus), Tongon (Randgold) and Bonicro (Newcrest). Other mineral commodities that offer potential for economic development in Côte d’Ivoire include diamonds, petroleum, natural gas, copper, iron, cobalt, bauxite, tantalum, lithium and silica sand.

The Agboville Project - An Exciting, Under-Explored Opportunity


African Gold has 100% of four granted contiguous tenements. The permits comprise a total of 1400km2 and are located 50 kilometres to the north west of the economic capital and largest city in Cote d’Ivoire, Abidjan.

The Project is located in the south east of the West African Craton, in an area referred to as the South-Comoe domain, part of what is referred to as the Birimian (Paleoproterozoic rocks of West Africa). This land is well located and considered to be a excellent prospective for gold. It is also considered to have potential for nickel, cobalt, copper, lithium, tantalum +/- niobium and beryllium.

Mineralisation styles within the tenements are:

  • Shear Hosted Gold Mineralisation
  • Layered mafic-ultramafic intrusion hosted nickel, copper, cobalt mineralisation
  • Lateritic nickel – cobalt mineralisation
  • LCT Pegmatites, potentially hosting lithium, tantalum, niobium and beryllium mineralisation

Until quite recently there is little evidence of any systematic modern exploration in the area. To date there has been no exploration drilling completed in the project areas, and the exploration concepts remain completely untested. A number of large (>15km), of robust, high tenor (max gold in soil 4.11g/t) gold-in-soil anomalies present walk up drill targets. Additional work is required to evaluate nickel – copper – cobalt and LCT pegmatite potential.


The Project is located in the south east of the West African Craton in an area referred to as the South-Comoe domain, part of what is referred to as the Birimian (Paleoproterozoic rocks of West Africa). At a regional scale in eastern Cote d’Ivoire the bedrock geology is characterised by an alternation of narrow bands of early Tonalite-Trondjhemite-Granodiorite intrusions, greenstones, volcano-sedimentary series and leucogranite intrusions striking roughly north east to south west. Numerous strike-slip faults and ductile shear zones are recognised across the region, mostly striking to the north-east.

At project scale the dominant rocks in the area are Birimian-age teriginous sedimentary rocks of the Comoe series comprising of sandstones with a phyllitic matrix, arkoses and pelitic layers. There are graphitic and conglomeratic units. Volcanic rocks are also present within the sedimentary sequence however they only form a minor component. Within this sedimentary package a number of leucogranites and layered mafic – ultramafic intrusions have been emplaced. Late stage pegmatitic rocks associated with the leucogranite plutons are present.

The volcano-sedimentary series are affected by D1 to D3 deformation phases of the Eburnean Orogeny which here manifested as a WNW directed shortening event. A number of regional scale faults/shears are mapped with this north east to south west trend. In addition ductile shear zones are often developed along the edges of the granites.

Mapped mineral occurrences on the licences include columbite, tantalite, monazite, copper, nickel, cobalt, manganese and chromite within the tenements, and lithium and beryllium to the immediate north of the Agboville tenement boundary.

Pegmatites near the township of Agboville, just north of the project area are known to be of the LCT type, and the likely origin of a number of tantalum, lithium and beryllium mineral occuances in the area. The lithium, beryllium, columbite and tantalite occurrences are likely to be associated with LCT pegmatites derived from the leucogranite (meta-monzogranite) intrusion in the north of, and extending beyond the tenement. Such pegmatites will be spatially associated with these intrusions. Pegmatites have not been identified by mapping within the Project to date.

Alluvial and elluvial gold mineralisation is known to the east and west of the project along the regional trend and recent exploration work in the project area has delineated a large and significant gold in soil anomlay. This soil anomaly trends to the north east – south west, suggesting that the gold mineralisation is associated with shear zones parallel to the regional structural trend.

Exploration to Date

Much of the area now covered by the permits which were previously held by Golden Star Resources who completed stream sediment; laterite and soil sampling. This work identifying two gold-in-soil anomalies. The first which is the broadest, is orientated east- west, 3.5 kilometres long and 1.5 kilometres wide. The second which is the longest, is orientated north east to south west and is in excess of 10 kilometres long and 1 kilometre wide. The maximum gold assay returning from the soil samples was 4.11 g/t gold. Exploration carried out to date has defined a number of significant, robust walk up drill targets.

No drilling has ever been undertaken on this project.

Exploration Potential

Gold – Although there was no gold occurrences reported within the tenements by the SODEMI project undertaken in 1996, the historical soil sampling by Golden Star Resources recorded significant gold values of up to 4,110 ppb gold over a strike length of over 10 kilometres in the north eastern portion of the Agboville licence. The anomalous soil values formed a large and very robust gold anomaly.  Such a soil anomaly represents excellent exploration potential and could host several gold deposits along its strike. The trend of the soil anomalism parallels a number of mapped structures corresponding to the regional geological and structural trend in the tenement and surrounding area. It is likely that the source of the gold in soil anomaly is gold mineralisation associated with a north east – south west trending shear (or shears), possibly associated with the regional folding which have axial planes/fold hinges parallel to the trend of these shears. In addition to this there are a number of anomalies defined during the regional stream sediment and laterite sampling programs that have yet to be followed up.

A number of targets have been identified within this soil data and are ready for drill testing.

The soil sampling should be expanded over the other areas of the tenement that, by the historical stream and laterite sampling suggest the presence of gold anomalism. This work could generate a number of significant gold targets suitable for drill testing.

Nickel-Copper-Cobalt +/- PGE – In the centre of the Project area outcrops a layered mafic- ultramafic intrusion approximately 9 x 4 kilometres in dimensions, elongate, like the granitiod intrusions in the area, in a north east to south west direction. Three other smaller intrusions are mapped to the north west, two of which in part lie within the Project tenements. A number of mineral occurrences are associated with these intrusions and are reported as copper-nickel, chrome-copper-nickel, nickel-cobalt, PGE-nickel-chrome and manganese-cobalt.

Lithium, beryllium, columbite and tantalite – Lithium, columbite and tantalite, or LCT bearing pegmatites are present in and around the granite intrusions surrounding the town of Agboville, just north of the project. And further east centred on the Adzope area. A number of Lithium, beryllium, columbite and tantalite occurrences are mapped spatially associated with several granitoids within and just to the north of the tenement suggesting that prospective pegmatites are likely to be present within the tenement.

Proposed Exploration Program

African Gold has proposed a dualistic multi-disciplinary exploration approach to evaluate the existing anomalies and generating new exploration targets. The proposed programs will target gold but also other known Li/Ta/Be and Cu/Ni/Co anomalies. The overall program will be phased with some later components of the program being contingent on positive results from earlier phases.

The proposed program will comprise: regional and detailed geological and regolith mapping; surface geochemical sampling programs, trenching and pitting; RAB, RC and diamond drilling and airborne and ground geophysical surveys.

Drilling is anticipated for early 2019.
