Lola Graphite Project – Republic of Guinea, West Africa

LOCATION

The Lola Graphite deposit is located approximately 1,000 kilometers east of Conakry, the capital of the Republic of Guinea. The deposit was named after the nearby town of Lola, located some 3.5 kilometers to the east.

The Lola Graphite deposit is present at surface over 8.7 kilometers with an average width of 370 meters, and up to 1,000 meters wide. The occurrence has a prospective surface outline of 3.22 km2 of continuous graphitic gneiss, making it one of the largest graphitic surfaces areas in the world.  The first 20 meters or so of the deposit are well weathered (lateralized), freeing graphite flakes from the silicate gangue and thus allowing for easy grinding and optimal recovery of all large and jumbo flakes. The graphite mineralization continues at depth within the non-weathered sheared gneiss.

SRG completed a total of 36 core drill holes (800 meters) on the Lola Graphite deposit in 2014. The drill holes were distributed over a strike length of 5.2 kilometers of the entire 8.7-kilometer-long deposit. The graphite mineralization is well exposed at surface over the entire strike length, with surface sample grades ranging from trace to up to 20% Cg (graphitic carbon). The mineralisation is often seen as agglomerates of high graphite concentration that can exceed 50% to 60% visible graphite content.

A 4,800-meter drilling program is underway on the property with an objective to delineate the National Instrument 43-101 resources. SRG expects to complete the program by the beginning of July 2017. Concurrently, the Company commenced an Environmental Baseline Study, which is being conducted by the Ivorian organization, SIMPA.

Metallurgical processing refinements will continue during the first half of 2017 in order to generate an optimized flow sheet.

SRG has contracted ProGraphite GmbH (“PG”) for advanced graphite test work on Lola Graphite. Laboratory work and analysis on the Lola Graphite concentrate will include, among others, purification testing, expandability and fraction analysis.

HISTORY

The French company BUMIFOM (“Bureau Minier de la France Outremer”) originally discovered the Lola Graphite deposit during construction of the Conakry-Lola road in 1951. BUMIFOM’s work on the property included 309 pits, metallurgical tests and the elaboration of plans for production. However, in 1959, following Guinea’s declaration independence, BUMIFOM abandoned the project and it was subsequently forgotten until 2012 when SRG re-discovered the deposit.

Metallurgy

Analysis performed on samples from SRG’s Lola Graphite deposit, including geochemical, mineralogical and metallurgical testing, yielded excellent results Tests returned purities of 99.7% and 99.1% graphitic carbon (“Cg“) for +48 mesh (>0.31 millimeters (“mm”) and the -48+80 mesh (between 0.18 mm and 0.31 mm), respectively using a light caustic acid wash (10% concentration). The majority of the concentrate, 89%, is made up of flake sizes greater than 0.18 millimeters. Super-jumbo flakes (>0.50 mm) account for 29% of the concentrate with purities of 96.6% and 95.9% Cg obtained using the basic flotation process.

Purity – The graphite concentrate appears to be exempt of contaminants (Cu, Mo, V, etc) that are often seen in higher concentrations in graphite concentrates from numerous other graphite deposits around the world and particularly in southern Africa.

Mineralogical studies show that all the sulphide minerals have been naturally leached from the oxide facies, resulting in a chemically purer concentrate.

For the same reason, the tailings are also expected to be non-acid generating.

Cost Effective One of our primary objectives is to establish mineral resources within the weathered portion of the deposit, the first 20 meters or so. The weathered material is easily accessible as it is outcropping at surface, there is no overburden to remove, and mining will not require blasting. SRG plans to process the material on site using typical flotation, thereby producing no harmful waste.

Proximity to Markets – Guinea, West African is coastal country, at only a few days shipping distance to Europe and to the American east coast, two of the fastest growing markets for high quality natural graphite flakes.

Graphite, the Future of High-Tech

The World needs new sources of energy and is moving away from fossil fuel to a much cleaner energy for cars and energy accumulators The developing world is evolving and natural flake graphite is the cornerstone of a new industrial revolution. It is anticipated that car manufacturers will increase their electric vehicle fleets by several fold over the next few years, further driving the demand for natural flake graphite. With this in mind, it is SGR’s intention to fast track the development of the Lola Graphite project.
