Sama Resources Inc (“The Company/Sama”) is a listed company trading on the Toronto Stock Exchange under the symbol SME.
The Project operates under a Joint Venture (JV) agreement between Sama Nickel Corporation (66% share; operator) and SODEMI (33%). The financial participation of the future JV would be as follows: Sama Nickel (60%), SODEMI (30%) and the Ivorian Government (10%). In case it is decided to not follow up on the Project, SODEMI has the option to terminate the JV and SODEMI will own all the exploration data and studies without financial compensation.

Summary:
Deposit Types
According to classical classifications of magmatic nickel-copper-PGE sulphide deposits, the Samapleu deposits are interpreted to occur as sulphides concentration within a differentiated, ultramafic and mafic feeder dykes system of the layered Yacouba complex. These rare intrusion types are host to the largest Ni-Cu deposits in the world, such as Jinchuan or Kalatongke (China), Voisey's Bay or Eagles Nest (Canada), Kabanga (Tanzania), Eagle (USA) and N'komati (South Africa).
The Samapleu mineralization is part of an ultramafic sequence part of the Yacouba complex, rather than of the type associated with a gabbro assemblage.
Geological Setting and Mineralization
The project area is located in the eastern portion of the Archean West-African Craton (WAC) that is represented by two shields: Reguibat to the north and Man to the south. The Man shield is subdivided into a western domain, predominantly of Archean age (Kénéma-Man), and an east-central domain (Baoulé-Mossi) composed of Paleoproterozoic rocks.
The Project lies within the Kénéma-Man domain, which consists chiefly of Archean granulitic and migmatitic gneiss and relic supracrustal belts with mafic to ultramafic rocks and iron formation. In turn, the Kénéma-Man domain is separated in two, and the project is located in the granulitic and migmatitic rocks of the southern domain.
The Yacouba mafic and ultramafic Layered Complex of Eburnean age has intruded the ........
Summary:
The mining method selected for the Project is a conventional open pit operation with off-highway haul trucks, hydraulic excavators, and wheel loaders.
The Project consists of three (3) separate pits (Pit A, Pit B, and Pit C) with one (1)waste dump designed close by to reduce haulage distance.
The mineralised material and waste rock will be loaded into off-highway haul trucks with excavators and/or wheel loader.
To properly manage water infiltration into the pits, sumps will be established at the lowest point of each pit floor. Water collected in the sumps will be pumped to a collection point at surface.
Samapleu mineralised material, contained into three (3) pits, are intended to be mined by surface operations. It is estimated that approximately 44.42Mt of mineralised material is extractable over a 20-year mine life.
The mine will operate year-round, seven (7) days per week, twenty-four (24) hours per day (2 shifts, 12 hours each). Since the mill will operate seven (7) days per week, a run of mine stockpile will be maintained to provide a constant supply of feed to the crusher with a minimum of one (1) month of production capacity. During the days when the mine is not operating (for technical or weather reasons), the crusher will be fed by the front-end loader from the stockpile or with a production truck. The mine fleet requirements and manpower are based on this work schedule.
