Sama intersects 36 m of mineralized material at Yepleu

2018-12-12 07:14 ET - News Release

Dr. Marc-Antoine Audet reports


Sama Resources Inc.'s first hole targeting Typhoon electromagnetic geophysical survey targets intersected 36 metres of mineralized material starting at a depth of 536 metres including a total of 10.75 m of semi-massive sulphides. Results obtained using the Niton XRF (X-ray fluorescence) analyzer are described in the associated table and include up to 5.18 per cent copper (Cu) starting at a depth of 543 metres and up to 3.56 per cent nickel (Ni) starting at a depth of 569 m. This mineralized interval hit what appears to be the edge of a structure very close to where the anomaly was modelled using Typhoon and is the first hole of a series of deep holes designed at testing high-conductivity targets defined by the phase 1 Typhoon at the 100-per-cent-owned Yepleu property at the company's nickel-copper-palladium project in Ivory Coast, West Africa. The drill hole is continuing and is now at 776 m from surface.

"We are very pleased with the results from this first deep drill hole as it confirms the exceptional potential for nickel and copper mineralization at depth in the large Yacouba layered complex. Additionally, we are very impressed by the accuracy of the Typhoon conductivity inversion. The hole hit the upper edge of the target leaving the remaining bottom two-thirds and the centre untested," said Dr. Marc-Antoine Audet, PGeo, president and chief executive officer of Sama Resources.

Downhole electromagnetic geophysics will be performed along the entire drill hole using the Typhoon system to help map the sulphides in greater detail.

The mineralization encountered in the hole is characterized by aggregates of the nickel, copper and iron sulphides pentlandite, chalcopyrite and pyrrhotite, respectively. Pentlandite occurs together with pyrrhotite, while the chalcopyrite is either mixed with the pentlandite and pyrrhotite or occurs as late millimetric to centimetric sulphide veins crosscutting the pentlandite and pyrrhotite

Contacts between the semi-massive sulphides and the mineralized pyroxenite and gabbroic host rocks are irregular but sharp and often show brecciated textures. This indicates that these sulphide lenses have intruded the host rocks and originated from a source that is yet to be discovered.

The associated table details Niton XRF measurements taken along lengths of semi-massive sulphide mineralization intersected between 536 m and 573 m. The hand-held Niton XRF analyzer provides assay readings for a wide range of metallic elements including nickel and copper. XRF readings are made on the core material through a window of a few square millimetres. Several readings are used to generate an averaged value. Reported values obtained using the Niton XRF analyzer are being used only for exploration planning.

The conductivity units used for the inversion performed 
using the Typhoon data are S/m (Siemens/metre). 
According to geophysicists, a chunk of pure nickel in 
lab conditions will be roughly 100 million S/m, but 
when you place massive sulphide mineralization in host 
rock and take the average conductivity of the 25 cubic
metres volume of rock (the process done in inversion), 
that one million S/m value will get diluted down to 
10 or 20 S/m.

The phase 1 Typhoon EM survey was performed following results from the 2,889-line-kilometre airborne helicopter time-domain electromagnetic and magnetic survey completed in February, 2018, over the Samapleu and Yepleu areas. The phase 1 Typhoon survey covered selected anomalies outlined by the HTEM survey. The company has planned a phase 2 Typhoon survey over additional EM targets.

Sama selected the Yepleu area for the phase 1 of HPX's Typhoon ground EM survey due to its high-quality HTEM response as well as the prospective geological setting. It is at the Yepleu area that Sama made the first discovery of nickel-copper sulphide mineralization at surface in West Africa. The Yepleu area is located 18 kilometres southwest of the Samapleu nickel-copper deposit.

The Samapleu-Yepleu mineralization is similar to conduit-hosted nickel deposits found elsewhere. These rare types of intrusions host the world's largest nickel-copper deposits such as Jinchuan (515 million tonnes at 1.06 per cent nickel), Voisey's Bay (137 million tonnes at 1.68 per cent nickel), Kabanga (52 million tonnes at 2.65 per cent nickel), Eagle (4.5 million tonnes at 3.33 per cent nickel), Eagle Nest (20 million tonnes at 1.68 per cent nickel), Kalatongke (24 million tonnes at 0.68 per cent nickel) and N'komati (2.8 million tonnes at 2.08 per cent nickel).

Sama discovered the nickel-copper-cobalt-palladium mineralization when it discovered the Yacouba layered complex of mafic and ultramafic rock. This layered complex was created approximately 2.1 billion years ago by the intrusion of magma through the Man shield. The Yacouba complex can be traced over a strike length of more than 50 kilometres within Sama's properties in Ivory Coast.

Core logging and sampling were performed at Sama's facility at the Yepleu field facility. Sample preparation will be conducted at the Bureau Veritas Mineral Laboratory's facility in Abidjan. Sample pulps will be delivered to Activation Laboratories Ltd., Ancaster, Thunder Bay, Canada, for assaying. All samples will be assayed for nickel, copper, cobalt, platinum, palladium, gold, iron and sulphur.
