Alberta Lithium NI 43-101 Technical Report

E3 Metals is developing Petro-Lithium – a new source of lithium from reservoirs associated with oil and gas production. The company is in the process of commercializing lithium extraction technology that has the potential to unlock the significant value from the expansive resource. E3 has three NI 43-101 Inferred Mineral Resources (Rocky, Clearwater and Exshaw) over our permit area in Alberta totalling 6.7 Mt (Resource Report) of LCE (Lithium Carbonate Equivalent). E3 Metals owns 74 Alberta Metallic and Industrial Minerals Permits totalling over 585,000 hectares, or 1.4 million acres, in Alberta, Canada (Permit Map). Our current resources cover only 34% of the total Leduc Reservoir that E3 Metals currently holds. The results from E3 Metals’ extensive sampling program across our greater permit areas show a similar potential (Sampling Map). Our mineral permits are strategically located in Alberta; a supportive and mature jurisdiction for Petro-Lithium development.

 Conceptual commercialized production facility

Petro-Lithium brine occurs deep within the Leduc Formation in Alberta as dissolved lithium ions in formation water. Of the total fluid contained within the pore space in the Leduc Formation, about 95% or more is Petro-Lithium brine. The Leduc reservoir exhibits exceptional flow rates and deliverability due to favourable rock properties and pressure.

Oil and gas production is restricted only to the upper portions of the reef; E3’s commercial development of the reef will involve deeper wells, potentially away from oil and gas production.

The Company’s exploration program is extremely cost effective due to existing oil and gas development. Brine is already being produced to surface from existing oil and gas operations, eliminating the requirement to drill new exploration wells for sampling. Strategic sampling locations were identified using the public database, which includes geological, production, pressure and geochemistry data. This database is a result of decades of hydrocarbon production in E3’s Permit and provides a comprehensive understanding of the Leduc reservoir characteristics.

Through the production of oil and gas in our permit area, E3 Metals has been able to mobilize quickly and efficiently to identify high-potential areas for sampling. The Company has established collaborative working agreements with 14 operators over the lease area. E3 Metals has been able to leverage existing infrastructure and the massive public well database in Alberta to produce two NI 43-101 resources with an extremely low finding cost ($0.18/tonne LCE) in a very short time frame (6 months). E3 Metals continues to sample the reservoir and will look to produce additional mineral resource estimates.

E3 Metals’ planned development model involves the use of existing oil and gas sites and the repurposing of infrastructure for production and processing of lithium brine. On these “brownfield” sites, E3 Metals’ brine will be produced at a sufficient temperature (70-100oC) and flow rate (up to 10,000 of m3/d per well), to generate geothermal heat and power on site. The use of this energy for the production of brine from the subsurface and processing of lithium at surface is expected to significantly lower both operating costs and greenhouse gas (GHG) emissions. The Company is confident that its development model will produce some of the world’s most environmentally responsible sources of lithium.

Extraction Process

E3 Metals believes the key to the feasibility of the project is the development of an efficient lithium extraction technology with the capability of selectively removing lithium from relatively low grade Petro-Lithium brines in the presence of impurities, while at the same time concentrating the brine volume.

 

E3 Metals’ lithium extraction process flowsheet. After producing Petro-Lithium brine to surface and generating any potential geothermal power, brine will pass through E3’s proprietary lithium extraction technology. This process will selectively remove lithium ions as well as concentrate the brine volume. Concentrated lithium brine will be further purified downstream using commercially available technology to produce Li2CO3 and/or LiOH. Lithium free brine will pass through the system and be re-injected.

 

E3 Metals’ lithium extraction technology is in the advanced stages of development through our partnership with University of Alberta. The U of A has developed a chemical process that has a high selectivity of lithium with the goal of achieving at least a 10x concentration factor at greater than 90% Li recovery while attracting less than 10% impurities. This low-energy concentration step will require no evaporation and provide a concentrate that can be purified by most off the shelf technologies available on the market.

Currently there are multiple commercially available providers of the purification and production steps of the flow sheet, and as such, achieving sufficient lithium concentration from Leduc brines using E3’s extraction technology will help prove the potential to unlocking E3’s significant lithium resource for Alberta.

E3 Metals is scaling this proprietary technology in partnership with two of Canada’s leading industrial facilities to finalize a commercially viable product. E3 is also in the process of testing concentration technology methods under development by leading third-party technology providers using the Company’s brine. This will identify potential options that may complement the Company’s process or provide an alternate solution.

The goal for 2018 is to have a lab based test facility of the lithium extraction process flowsheet operating and producing lithium concentrate. This will lead to the design and construction of a field based pilot plant in 2019.
