Presentation Overview • MétAmpère - past projects • MétAmpère’s objectives in Cornwall • Challenges of unique Cornish lithium mica – Risk factors – Zinnwaldite vs Spodumene • MétAmpère achievements in Cornwall – Extensive metallurgical testwork completed 2017- 2019 – First drilling completed 2019 2

Who We Are • MétAmpère Limited aims to develop battery metal projects in a friendly jurisdiction • The founders have considerable experience delivering resource projects. We specialise in extractive metallurgy and plant development • Our past projects: – Windiummura Vanadiu m ($500m commissioning) – Hinda Phosphat e ($67m –Start of construction) – Cinovec Lithium ( $13m Spent to PFS) Founding Shareholder and Project Manager www.metampere.com 3

Past projects 4

Strategic Context • UK Government has ambitious plans for EVs and energy storage and has invested heavily in EV battery research & development • UK Car sales down 45%, investing in EVs to cost £billions • Commercial battery production requires lithium • No battery lithium is produced in UK or Europe • Lithium production UK would give a strategic advantage over EU • In 2019 MétAmpère drilled the first lithium exploration holes in British history ! • Will finish prelim economic evaluation by Q4 2019 5

Lithium in Cornwall Granite • The occurrence of lithium in Cornwall and Devon granites has been known for decades, with many academic studies completed • All granites contain feldspar, quartz & mica • Some Cornish mica is enriched in a lithium-ferrous mineral “Polylithionite-1M” (XRD Analysis) – This mineralisation is similar to, but subtly different to the micas of the Zinnwald region • Hydrothermal decomposition of some feldspar forms kaolinite clay • Clay is mined by monitors and purified by removing quartz sands and mica using physical separation • Quartz sands and micas are commonly dumped separately • Un-kaolinised granite (“stent”) is dumped in surface tips www.metampere.com 6

MétAmpère’s Goal Build a quarry & integrated processing facility to produce +20 ktpa of battery grade lithium carbonate (Li 2 CO 3 or LCE) This scale is required to ensure: • – Significant market presence – Economies of scale – Engagement with off-takers (battery makers) – Government, community interest and support Resource Requirement • – Enough for +20 year mine life – Quarry and concentrate @ 2 Mtpa of Ore & – Minable Reserve of +40 Mt required This output would help secure UK strategic lithium requirements, satisfying requirements for 350,000 electric cars per year 7

Risk Factors • No detailed records on composition of mining wastes • Finding a large enough deposit with high enough grade • Large footprint required • New lithium mineral “Polylithionite-1M” – Extensive Research & Development required • Developing a metallurgical process that economically produces saleable battery-grade product • Securing product offtake agreements – pilot plant required for certification • Permitting & development finance 8

Zinnwaldite Vs Spodumene Spodumene Zinnwaldite Not currently processed. Only hard-rock lithium production Cinovec/Zinnwald only proposed Current mining source projects Li Mineral LiAl(Si 2 O 3 ) 2 KLiFe 2+ Al 2 Si 3 O 10 F 1.5 (OH) 0.5 Composed of tetrahedral and Structure TOT octahedral nets C 2/m Lithium grade Li 2 O 8.03% (pure mineral) 3.42% (pure mineral) Typical ROM grade Li 2 O 6,500 (Cinovec Reserve 12,000 ppm statement) Leach extraction low temp acid roast high temp neutral roast High, due to composition and Impurities low high temp roast Potential By Product Tantalum, Tin Tin, Tungsten & Potash Flowsheet Proven, operational Theoretical Capex/Opex More expensive then brines Highest Existing refining plants take Bespoke dedicated refining plant Sale to refining plant spodumene concentrate required 10

MétAmpère's Progress • Unravelling 300 years of mining and exploration in Cornwall – Identifying source of residues in dozens of sand-dumps / mica-dams Revalidating old academic data – Developing detailed understanding of lithium genesis – • Mineral Tenure Review Mineral tenure review by Cornwall lawyers – MétAmpère has digitising title plans to produce detailed mineral ownership maps – • GIS (3D Mapping) British Geological Society – MétAmpère re-assayed historical BGS samples, revalidating mapping – Digitised historical survey maps, production records, lidar data – – Calculating mined volumes, backfilled pits, stent, sand and mica dumps Metallurgical Test work • Beneficiation testwork completed on dozens of samples – – Mineral characterisation, SEM –INCA, XRD & QEM – Roast and leach of Lithium Mica Concentrate Field Work • – Field mapping and channel and grab sample collection – Residue collection & analysis of current china clay waste streams – CSM -Masters projects Drilling Program • – 6 Reverse Circulation holes completed April/May 2019 – Targeting Maiden JORC Resource Statement 11

Cornish Granite Beneficiation Tests MétAmpère's Pilot Plant 13

Lithium Mica Testwork Mica requires a novel process flowsheet for two stages 1. Concentrating lithium-mica (+38,700ppm Li 2 0) using novel beneficiation of Run of Mine material Understanding variations in mineralogy, metallurgical • response and deleterious minerals 2. Lithium extraction and refining to produce battery grade lithium carbonate Metallurgy, Quantitative-XRD, roasting optimisation • MétAmpère has extracted lithium into solution. Now • a refining problem 14
