Adzopé’s exclusive research permit (PER) is located near Abidjan in south-eastern Ivory Coast. It covers a total area of 186 km². OMCI completed the acquisition, in 2013, of the Adzopé mining permit from Newmont Mining. This permit is currently being renewed. During the first drilling campaigns, two zones proved to be particularly interesting : * Zone of Kong – 64 drillings – 3,508 meters: gold anomalies *Zone of Adonkoi – 44 drillings – 3,145 meters : 2m@5,4g/t, 12m@1,54g/t, 4m@5,49g/t, 2m@10,8g/t The entire area explored is characterized by highly maintained agricultural fields. We find fields of cocoa, rubber, coffee as well as mandarin trees, manioc and grapefruits which will make it very difficult to develop the site. Mineralization appears subvertical and this type of mineralization can be difficult to target and study by drilling. Despite some interesting anomalous zones, this permit by its context and geology does not demonstrate an interest that would justify an additional exploration campaign.
2015 Auplata acquires OMCI in Ivory Coast and Groupe Atlantique takes a stake in OMCI.
2016 Exclusive negotiations between AUPLATA and Newcrest for a strategic agreement in Ivory Coast.
On the 25th of February 2015, the Council of Ministers granted OMCI, for a first period of 4 years, two PERs called PER Mont Goma Sud (445 km²) and Mont Goma Nord (228 km²), for a total area of 673 km². These two PERs are located some 12 km southwest of the city of Seguela in western Ivory Coast. Between 2009 and 2010, a geochemical prospecting campaign revealed 4 anomalies that should justify the continuation of the exploration on
these two PER. These gold occurrences seem to occupy privileged positions, meaning that they are located at the edge of the Intrageo-synclines or (IGS) that control almost all the gold regions in the Ivory Coast. The search for gold deposits along the SEGUELA shear zone deserves further examination.

Tabaroucht Mine (Copper):
The Tabaroucht mining area located 50 km southeast of the town of Beni Mellal Fig 2, contains a copper mineralization hosted in a layer affecting the Cretaceous sandstones and the base of the Dogger limestones. This layer shows a dimension 250 m by 250 m on a power of 12 m, slightly sloping to the north and flush in some places. The copper mineralization is 70% oxidized. CMT has carried out several preliminary research works on these mineralizations (soundings, small wells, two galleries). This work made it possible to estimate the resource reserves in this area, which amount to more than 2 million tonnes of ore with a copper content of 1.4%. The tests for the treatment of this ore are in progress.
The mining center of Tighza is located in the administrative region of Meknes – Tafilalet, in the Middle Atlas, 5 km from the town of M’rirt (90 km south of Meknes).
The farm occupies the center of an area of high hills rising to 1,494 m at Jbel Aouam, and between the trays of M’rirt southeast and Tanadra west.
Geologically, the mining center is located in the northeastern part of Hercynian Morocco. It is integrated in the evolution of the magmatic and hydrothermal events of the northern part of the Moroccan Meseta and is characterized by four granitic points and Pb / Zn / Ag / Au / W polymetallic mineralizations:
. Lead, zinc and silver in the form of MF veins, galena and silver blende
. Gold, vein or in skarns, bound to quartz and sulphides
. Tungsten stratoid and vein, in the form of scheelite and wolframite.
Key figures
. Annual production: 320 000 ttv, 25 600 t of Pb-Ag concentrates, 4 300 t of Zn concentrates.
. 3 seats in operation
. Hollow vein structures and rooting known from surveys over 1000m
. Staff: 300 people, including 25 executives
. Research budget: 35 to 50 million dh / year
. Annual investments: 40 to 45 million dirhams.
Ore extraction
The Tighza mine is underground and operates 3 veins: Signal, Ighrem Aoussar and Sidi Ahmed. Each of the three operating headquarters has two main wells, one for extraction and the other for service. These wells reach depths of more than 750 m.
The exploitation of the Tighza site currently uses three methods of exploitation, according to the morphology of the deposit and its geotechnical characteristics (land holdings, deepening of mineralization, width of mineralization, mineralization richness, water presence, etc. .).
The mining cycle at the Tighza mine can be illustrated as follows:
Production background – Extraction – Processing
The reserves and exploitable resources of the Tighza mining site, calculated at the end of December 2017, amount to more than 5,977 Kttv of ore. The average geological grades at the end of December 2017 are 7.54% for lead, 1.06% for zinc and 147 gr / t for silver. The research work carried out in parallel with the operation is intended to rebuild the reserves, prepare the mine and consequently extend the life of the mine site. These have made it possible over the last few years to restore them beyond exploited tonnages. Research work consists mainly of:
Geophysics and geochemistry from the surface.
Soundings from the day or from the bottom of the mine;
Mining works (galleries, wells and chimneys);
The evolution of resources and reserves between 2016 and 2017 is detailed in the following table (in Kt):
Midelt lead field:
The veins of Hautes Moulouya are located in the province of Midelt. Since 2011, a research program involving topo-geological work, sampling and core drilling surveys has been carried out in this area. No less than 9000m of daytime soundings were carried out. The results are encouraging and have highlighted resources from about 1,500,000 t to 4% Pb. A subsidiary of CMT has been created, MINREX, to take charge of the development of this project.

Le permis exclusif de recherche (PER) d’Adzopé se situe près d’Abidjan dans le sud-est de la Côte d’Ivoire. Il couvre environ 186 km². OMCI a conclu l’acquisition, en 2013, auprès de Newmont Mining du permis minier d’Adzopé. Ce permis est actuellement en cours de renouvellement. Au cours des premières campagnes de forage, deux zones se sont révélées particulièrement intéressantes : *Zone de Kong – 64 forages – 3 508 mètres : anomalies aurifères *Zone d’Adonkoi – 44 forages – 3 145 mètres : 2m@5,4g/t, 12m@1,54g/t, 4m@5,49g/t, 2m@10,8g/t. Dès renouvellement du permis, OMCI est déterminée à poursuivre les campagnes de forages, en s’appuyant sur son partenaire industriel et financier, afin de valoriser un potentiel qui pourrait atteindre le million d’onces sur ce permis.

Domaine plombifère de Midelt :
Les filons de la Hautes Moulouya se situent dans la province de Midelt. Depuis 2011 un programme de recherche comportant des travaux topo-géologique, d’échantillonnage et des campagnes de sondages carottés ont été réalisé sur ce domaine. Pas moins de 9.000 mètres de sondages carottés on été réalisés à ce jour. Les résultats sont encourageants et ont permis de mettre en évidence des ressources d’environ 1 500 000 t à 4% Pb. Une filiale de CMT a été créée, MINREX, pour prendre en charge le développement de ce projet.
