Spherical Carbon Coated Graphite - 100% Owned

The lithium-ion batteries for manufacturing plants being built NOW to meet expected demand will require steady and reliable supplies of spherical carbon coated graphite, and no one in the world is able to produce and deliver at sub US$2,000 per tonne except for Saint Jean Carbon Inc via its proprietary patented (pending) technology. The Company is targeting securing an offtake agreement for its technology, and are bound by confidentiality and non disclosure agreements from saying with who, but most people looking at their specifications of material are logically immediately able to take the leap and say its Tesla. Plusnews of SJL.V appointing Dr. Zhongwei Chen PhD, MSChE, BS as Chief Technology Officer is very telling as he is known in the industry as the foremost expert on Li-ion battery technology in the world and consultant to several majors. The end result, bottom line, should see Saint Jean Carbon Inc. profitably get to companies in the like of Tesla in Nevada and see US$1,950 per tonne spherical coated carbon graphite and make US$600 to US$700 on every tonne.

Saint Jean Carbon has developed an exclusive patented manufacturing system that creates the material; jet-mill/grinding it, then shaping it, and coating it, all in one go, and then applying it directly to the anode that goes into a lithium-ion battery. The Company's mill is a process that will be situated at (or attached to) the battery plant facility of the electric vehicle manufacturer, in say Nevada. The offtake deal will involve SJL.V supplying the raw graphite materials according to spec, either by sub-contract or mining it themselves (if need be as a back-up); the company has well vetted detailed engineering models involving ~120 small high-grade high-purity graphite pits on its own properties. Graphite material that goes into lithium-ion batteries is 99.875% pure, it has no dampness to it, and all the impurities are eliminated from it. SJL.V has developed a system that crushes and grinds its ore, and air classifies it through a windowing system, further grinds it, and loads it to railcar for delivery to its processing mill. Ideally the Company can avoid using its own properties; SJL.V has been offered material by two very large Chinese producers of graphite at a base cost that would be the same as (or less than) the Company's cost to mine here in exchange for a cut of the high-graded material. SJL.V's strategy is to use others graphite first, if possible, as graphite is basically a commodity and the real value in graphite for the Li-ion anode is in its technological process. Regardless of the source, SJL.V will ensure the mine signature and finished material DNA are compatible, as unique and exacting specifications are required for all materials to work together in the end battery.

Leaving nothing to chance, SJL.V is retaining full control of the process, at least for this first offtake; the Company is expected to own the mill equipment, lease space (for free) at the manufacturer, supply its own raw material, and man its own equipment. There is an expertise that SJL.V brings to the table that no one else on the plant has proved they can replicate and majors have taken notice.
