The Doropo Project, located in the northeast Côte d’Ivoire, consists of nine permits, over a 1,930km2 highly prospective landholding that lies between the Boromo-Batie and the Hounde-Tehini greenstones belts.

The Company began extensive exploration at Doropo in late 2015, leading to a maiden resource declared in 2017. The Company’s experienced exploration team has achieved year-on-year resource growth. The team applies a systematic approach to prioritise resource-focussed target generation and ranking to fast-track the most prospective target.  

The Main Resource Cluster contains a 2.4Moz Indicated and 1.0Moz Inferred resource, drilled to 250m from surface depth.

Latest Doropo technical report

The Doropo landholding lies entirely within the granitic domain, bounded on the eastern side by the Boromo-Batie greenstones belt, in Burkina Faso, and on the western side by the Tehini-Hounde greenstones belt.

At the project scale, the geology consists of a granite-gneiss terrain, the granite being mostly of coarse granodioritic composition, bound by major bimodal greenstone belts, which express progressive assimilation and strain gradients at the margins, evidenced by the presence of pyroxenites and amphibolites in the volcanic suites and migmatites in the granitoids (mostly on the western side).

Gold mineralisation occurs late in the regionally-extensive, reactivating compressional shear networks, framed by intense silica-sericite-carbonate alteration haloes. The main structural hosts are cross-cutting quartz veins with diffuse overprinting with fine to medium grained pyrite sulphide selvages. Gold grade correlates with the density of pyrite and high grades are correlated with native gold within the structural laminations and contacts of the quartz veining.  The veins range up to several metres. Late regional, post-gold, doleritic dykes intrude along a number of the gold-bearing shear structures.


The currently defined mineral resource deposits lie within a 6km radius. Souwa, Nokpa, Chegue Main and Chegue South, which hosts 75% of the total mineral resource, are clustered within a 3km radius of a proposed plant location. Han, Kekeda Tchouahinin are satellite deposits located 4 to 6km to the southeast and Enioda sits 12km to the east.

The Souwa deposit currently hosts the largest resource and remains structurally open in all directions. Mineralisation extends over a 2.6km strike and dips 25o west to greater than 250m vertical depth.  Nokpa is centered on a high-grade WNW moderately plunging shoot. The high-grade core sits in a 200m long dilational jog created at the intersection of 3 major structures; the major Nokpa-Chegue Main shear, the Souwa shear, and a third major fault infilled by late dykes.  Mineralisation extends to 300m vertical depth and remains open.

Drilling has successfully connected both Chegue Main and Nopka, along a 2.4km strike mineralised structure. Similar in origin to Nokpa, Chegue South hosts a significant resource immediately south of the Nokpa-Chegue Main shear zone.

Tchouahinin, located centrally within the resource area, 3km between Souwa and Kekeda, is a new satellite deposit. The mineralisation is currently defined along a 700m strike and remains open in all directions. At the Enioda deposit, drilling successfully bridged two smaller shoots into a coherent 2.2km long surface deposit which strikes north to south and dips 40° west. Enioda forms the southernmost section of a continuous 7km regional mineralised shear.

Outside of the 6km radius Main Resource Cluster, regional Doropo exploration focused on generative geochemical surveys on Tehini 1, 2 and 3 permits, Gogo and Bouna. The most significant discovery was the Kilosegui anomaly, a coherent 8km long gold in soils-auger anomaly with a strong subjacent magnetic structure, located 35km south-west of Souwa, straddling the Tehini 1 and 2 permit boundaries.  Further new additional target anomalies were defined in Kalamon, Danoa, and Gogo permits.
