Saturday, April 25, 2020 Unconventional Lithium Eschewing Hard Rock and Salares + Unconventional Lithium sources have gained space as disappointment with the financial woes of spodumene projects and long-lead time of salares projects have cast a pall over those modes of production + Resources, particularly oilfield brines, are potentially enormous + Most mooted projects are in top-grade jurisdictions + Technology can overcome low-grade and advance a project over those with higher-grade but in more challenging locations + Unconventional Lithium projects appear to be more scalable Almost universally the grade of Lithium in the unconventional sources is lower than from the more commonly exploited hard rock and salar projects Technologies for extraction of the Lithium are still in evolutionary stages Establishing a resource from the unconventional sources is difficult and that then presents challenges with estimating project economics Mine water sources can be limited in their amount of resource even with replenishment The Lithium price is currently blighted by perceived over-supply and weak EV demand and this is constraining financing of projects of any “style” of mineralisation Going Unconventional The bulk of the world’s lithium supply currently originates from two main resources: hard rock and brine deposits form salares. Attempts at promoting other non-brine options such as micas/clays have not proven efficient or cost-effective. However in the brine space there are options beyond the tried & true salares model as pursued in Argentina, Chile and Nevada. The unconventional lithium sources we shall look at here are being touted by a small group of players and consist of brines from mine waters, geothermal brines and brines from oil & gas fields. In this report we shall look at these potential sources and mention in passing the companies that are endeavouring to extract lithium from these “resources”. Lithium Outlook Until the latest “virus crisis” we would have posited that there was a good prospect for the recovery in EV demand and thus for Lithium prices. EVs essentially disappointed the much vaunted projections in 2019 due to Chinese demand being flaccid due to the removal of subsidies, disinterest in broader EV Hallgarten & Company +44 795 08 53 621 Page 1

Product and Development Focus for Infinity Turbine

ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.

Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system.

Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications.

We call it the Cogeneration Battery or Cogen Battery.

One project is converting salt (brine) based water conditioners to simultaneously produce power.

In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).

Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).

We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.
