Amblygonite and it's economic uses, page-2

At the bottom of the page is an excerpt from lepidico's 2017 Annual report. This technology, applied to Cougar's resource, would enable battery grade lithium production from our Brazil project. We had some excellent results from our initial sampling so if those higher grade metals are available in large quantities, we will be in business big time. IMO, providing the resource is proven and production was feasible it would be great for Cougar to enter a JV (but under Cougar's terms this time) and get into early production.
There is also strong demand for Cobalt too. Maybe worth looking into Pyke Hill again, or even a new project.
Pyke Hill Project (Western Australia) Cougar Metals NL holds the nickel and cobalt laterite rights to the Pyke Hill project situated on tenement M39/159 east of Leonora, Western Australia. Previous exploration drilling conducted by Cougar Metals NL at the Pyke Hill Project delineated a measured and indicated resource, using a 0.5% nickel cut-off grade, of 14.7M tonnes at 0.90% Ni and 0.06% Co, which contains 131,000 tonnes of nickel and 8,800 tonnes of cobalt.
Graphite, Lithium and then Cobalt for the trifecta? Cheers, E

Pre-Feasibility Study – Phase 1 L-Max® Plant During the year, Lepidico completed a Pre-Feasibility Study (“PFS”) on a Phase 1 L-Max® Plant, conducted by lead consultant MinMet Services Pty Ltd. The Study was based on a small scale commercial L-Max® Plant (“Phase 1 Plant”) processing a lithium-mica concentrate feed at a rate of 3.6 tonnes per hour (tph) to produce approximately 3,000 tonnes per annum of battery grade lithium carbonate and a suite of valuable by-products.
The PFS highlighted the considerable economic benefits of a Phase 1 L-Max® Plant strategically located in Ontario, Canada, close to sources of bulk consumables, established infrastructure and markets for bulk by-products, rather than close to sources of lithium-mica concentrate feedstock.
Strategic positioning for the Phase 1 Plant means consumable and labour related costs are minimised and by-product potential is maximised, allowing lithium-mica concentrates to be shipped over considerable distances and potentially half-way around the world for high quality feed.
An assumed concentrate feedstock price of approximately US$350/t was used for the PFS, based on a quoted supplier price, inclusive of feed preparation and shipment costs. This figure also reconciles well with the prevailing spodumene market price, as adjusted for the lower lithium content of lepidolite concentrate.
