Sama Resources Inc./Ressources Sama Inc. (TSX VENTURE:SME) ("Sama" or the
"Company") is pleased to announce that the Samapleu and the newly discovered
Yepleu nickel-copper-palladium deposits are hosted within a newly identified
large anorthositic and dioritic layered complex (the "Yacouba Layered Complex")
in Cote d'Ivoire, West Africa.
Sama's newly discovered Yacouba Layered Complex, which hosts the Samapleu and
Yepleu nickel-copper-palladium deposits, sits in a favorable geodynamic position
at the eastern edge of the West African Archaean craton in the vicinity of the
major Sassandra fault system.
Members of the Yacouba Layered Complex have been identified at surface over a
corridor of approximately 10 kilometers ("km") wide by 25 km long. Additional
work is required to identify the full extent of this new layered complex on a
regional basis.
The Samapleu (subject to Sama's fully funded 3 year PhD program with University
of Franche Comte, France) and Yepleu deposit's mineralization and geological
characteristics are typical of a layered Pipe- like Intrusion or conduit-hosted
nickel deposits.
These rare type of intrusions host the world's largest nickel-copper deposits
like Jinchuan, 515 million tonnes ("Mt") at 1.06% nickel; Voisey Bay, 137Mt at
1.68% nickel; Kabanga, 52Mt at 2.65% nickel; Eagle, 4.5Mt at 3.33% nickel; Eagle
Nest, 20Mt at 1.68% nickel; Kalatongke, 24Mt at 0.68% nickel and N'komati 2.8Mt
at 2.08% nickel.
Geo-chronological data (PhD Thesis in progress- article submitted to Bulletin de
la Societe Geologique de France (BSGF), January 24, 2014) indicate that the
Yacouba's mafic and ultramafic hosts were intruded within the older gneissic
assemblage at a Proterozoic age of 2.09 Ga (U-Pb, measured on rutile).
It's interesting to note that the age of 2.09 Ga for the Yacouba Layered Complex
is almost the same as the large and mineral rich South-African Bushveld complex
2.06 Ga host of the Ivanhoe's large Flatreef palladium-nickel deposit and
numerous other chromite Platinum Group Elements ("PGE") deposits and surrounding
N'Komati nickel-copper-palladium deposit, 2.04 Ga.
Samapleu and Yepleu deposits are typical magmatic nickel-copper-palladium
deposits with common metallurgical characteristics. Nickel and copper
mineralization (pentlandite, chalcopyrite, combined with pyrrhotite, rarely
pyrite) correspond to sulphide disseminations ranging from trace to 40% and
semi-massive to massive (40% to 100% sulphides) sulphide rich lenses most often
spatially associated with highly breccia texture in pyroxenites.
Semi-massive and massive sulfide veins display a number of characteristics
suggesting they are part of a larger mineralizing system:
1. Extreme variations in nickel:copper ratio indicative of fractionation of
sulphides.
2. Association with varied textured and brecciated facies.
3. Presence of an unusual texture called loop texture. Large pyrrhotite
crystals (5cm in diameter) are rimmed by smaller chalcopyrite and
pentlandite that define a loop that encloses the pyrrhotite. These
textures are seen at Norilsk and Voiseys Bay nickel-copper-palladium
deposits.
4. Abundant sulfide inclusions (globules) within pyroxene crystal
indicating sulfur (S) saturation took place before pyroxene
crystallization (at depth).
Exploration Model and Targets
Exploration to date has focused mostly on shallow targets (less than 150m) at
the Samapleu and Yepleu deposits. Sama believes that mineralization at the
Samapleu deposits could plunge deeper and could extend laterally as suggested by
responses obtained from the Helicopter Electromagnetic survey completed in
January 2013 and by the current DHEM survey.
At Yepleu, the Company is chasing structural features that would have trapped
mineralized pyroxenite within the sub-horizontal large layered complex.
Yepleu drilling program and results
The Yepleu discovery is located 18 km southwest of the Samapleu
nickel-copper-palladium deposits. Regional geological mapping has identified
that the geological host of the newly discovered Yepleu nickel-copper-palladium
mineralization extends beyond the original 3 km by 600 to 800m to an area as
vast as 6 km x 4 km (refer to News Release dated February 03, 2014).
Tables 1 and 2 below summarizes mineral intersections for each hole drilled at
the Yepleu discovery. Drilling is performed using the Company's 100% owned
Coretech CSD 1300G drill rigs.
Intercepts were defined using 0.1% nickel cut-off grades for 6 holes which
samples were sent for assays through Veritas Laboratory in Abidjan (refer to
News Release dated January 14, 2014). For the other 12 holes, mineral intersects
are reported as visual estimates of sulphide content and in some cases with
nickel and copper values obtained using the hand held Niton XRF analyser
("Niton").
Core logging and sampling was performed at Sama's facility in Yorodougou
village. Sample preparations were performed at Societe de Developpement de
Gouessesso's sample preparation facility in Gouessesso village under Sama's
supervision. Sample pulps were delivered to Bureau Veritas Mineral Laboratory's
facility in Abidjan ("BVML") and then dispatched by BVML directly to their assay
laboratory, Ultra Trace Pty, in Perth, Australia. All samples were assayed for
nickel, copper, cobalt, platinum,palladium and Gold.
The Niton provides assay readings for a wide range of metallic elements
including nickel and copper. Readings are made through a window measuring a few
square millimeters through the plastic bag of the pulverised and homogenized
(-100 mesh) sample. Several readings are used to generate an averaged value.
Reported values obtained using the Niton are being used only for exploration
planning.
