Coomtech Limited UKQAA Meeting 30-04-2019 Coomtech SMR Technologies Update “Low Energy Low Cost Drying For Bulk Materials” 1

Coomtech Limited - Business Update ➢ Coomtech Limited is continuing development of all three of its drying technologies: ❑ SMR - now at market - continuing development ❑ TMR – in development (circa 18 months) ❑ IMR - in development (circa 36 months) ➢ We are raising funding in an A-Round for growth and are in the – expecting to close in Q2. ➢ Since last presenting at the UKQAA we are building commercial momentum: ❑ Plant 1: in ash processing for the cementitious industry in and around Greater London and proposed for Thamesport on the Medway in Kent ❑ Plant 2: coal treatment plant in Australia – Latrobe Valley ❑ Plant 3: an ash plant in the USA 2 “Low Energy Low Cost Drying For Bulk Materials”

Coomtech Market Position ➢ Clarification of position – Coomtech is a technology provider - NOT ash sellers ➢ Building a plant at Thamesport however we will NOT own that plant ➢ Presently two financial institutions capable of “project funding” operating - vying for the build ➢ However it is of course our industrial demonstration plant and accessible to Coomtech: ❑ We want to be able to show SMR in operation ❑ We will be continuing to develop and of course overcome operational issues inevitably arising ➢ We are about facilitating partnerships for: ❑ In the Supply chain to clients ❑ For Off-take from clients ❑ Through cooperation's in engineering and process integration for clients 3 “Low Energy Low Cost Drying For Bulk Materials”

Coomtech & Fairport Engineering ➢ Why Fairport Engineering as partner? ❑ Reputation and reliability ❑ Sector experience (cement, minerals, energy) ❑ Capacity ❑ Co-investment in final development phase Cement Plant ➢ Engineering Partner’s Role: ❑ Integrating client specific needs Site design ❑ Engineering, Procurement, Commissioning Ash Handling ❑ EPC wrap ➢ Currently Fairport EPC guarantee the capability of a plant for throughput and aspects of operation ➢ Fairport are currently testing ashes utilised at Thamesport Recognising variances occurring from source to source, in ➢ moisture, particle distribution, characteristics and drying. ➢ Completion expected in May -19 ➢ Addition of moisture removal to the EPC wrap 4 “Low Energy Low Cost Drying For Bulk Materials”

Coomtech SMR Process Status Summary ➢ Patent – International cover including Europe, USA, Canada, Australasia, India, Indonesia ➢ Market Readiness – plant approaching final designs for Thamesport mid year ➢ Trials – Fairport’s system is embarking on a series of longer runs at 50 -300 tonnes on their design ➢ Scale – increasing capacity is a case of increasing modules of lines NOT increasing pipe size (Yet) ➢ Throughput – currently 1-1.5mtpa – subject to materials and moisture content ➢ Sizing – always targeting to process at <5mm for optimal performance ➢ Moisture removal – achievable down to 3% for blocks etc and below 0.5% for cement needs ➢ Manufacture – 80%+ of the plant is off the shelf ❑ Drying cartridges - have two UK manufacturing sources under Coomtech control ➢ Ongoing Development - for Thamesport and after for: ❑ Ash market ❑ Coal market ❑ Construction products 5 “Low Energy Low Cost Drying For Bulk Materials”

Thamesport Layout Options ➢ Thamesport site plan Options Considered for planning submission for UP TO 200,000mtpa eventually - initially 100,000mtpa capacity – Up to 36 lines in linked modules of 6. Total Site up to 1.6Acres (excl. stockpile) ➢ Primary stockpile adjacent to end wall for feed to working area and process stockpile Covered Processing Area Includes Short Term Stock 6 “Low Energy Low Cost Drying For Bulk Materials”

Post Processing Handling & Dispatch 6. ➢ Energy – to create independent stand alone plant: ❑ Energy source LNG – supplier Molgas – provide full plant and service for contract life ❑ CHP Engine - supplied by Gruppo AB – Ecomax Engines ❑ Requirement – power to drive plant, adequate heat production to maintain 80 0 C in the process air at all times 9 “Low Energy Low Cost Drying For Bulk Materials”

Pre-processing Raw Materials & Stockpiling ➢ Target Sizing = <5mm ➢ On client/supplier site: ▪ Screened & Crushed to achieve <5mm by for transport wet by road, rail or ship - removing major hard conglomerates and foreign bodies ▪ Recognising wet ash responds to handling and transport – compacting / agglomerating ▪ Delivery to Coomtech site via tipper / sea vessel + clamshell grab & conveyors/ Samson style loader etc. ➢ Target Moisture = (Band to be agreed with client) 15- 20% at processing ➢ On Coomtech SMR site: Internal Processing Stock from Stockpile Bulk stockpile (e.g. up to 40,000 at Thamesport) ▪ Magnetic detection ▪ Pre-processing storage at plant ▪ Overhead Magnets Final Vibrating Screens ▪ Final screen to <5mm 10 “Low Energy Low Cost Drying For Bulk Materials”

Coomtech SMR Plant - Feed Section Constant feed from Pre-processing stockpile to the SMR system feed section by bucket loader “Low Energy Low Cost Drying For Bulk Materials” 11

Feed Steps: ➢ Objective To Optimise 1 to1.5tph at material specification ▪ Feed table supporting feed belts moving across lines Side Elevation ▪ Sweep the table in to lines via linked steep sided Bucket Loader Feeding Up To Sweep Table Lines hopper ▪ Above a rotary valve feeding product in to a air stream ▪ Objective for the air stream is to suspend the product Multiple Module ▪ Lean phase in the suspension section of each line Feed Each Line Independent ▪ At appropriate rate for line performance relative to specification ▪ Air volume and air temperature Plan View Of The Line Hoppers Feeding Down to Rotary Valves And To Suspension ▪ Ready to enter the SMR Drying section Zone Of System 12 “Low Energy Low Cost Drying For Bulk Materials”

Coomtech SMR Plant Drying Zone Coomtech’s patented process uses turbulent air to remove moisture from the surface of particle (i.e. air drying of materials) . Our patented process is called Surface Moisture Removal (“SMR”). Using air (as opposed to heat) maintains the mineral chemical composition and is lower in energy requirement. Drying Section Drying Cartridge Plenum Creates: (Uninsulated) Managed Turbulent Air Inside Drying Cartridge: Plenum Chamber Sheers Surface Moisture Off Particles No Moving Parts “Low Energy Low Cost Drying For Bulk Materials” 13

SMR - Air Operating Temperature Particle time in process < 1 Second – at 80 0 C = no time to dry Optimise water carrying capacity of air in process “Low Energy Low Cost Drying For Bulk Materials” 14

Coomtech SMR Plant Receiving Section ➢ Slow the product down ➢ Maintain separation of the particles and water ➢ Potential to manage particle distribution with cyclone ➢ Manage dry product to storage ➢ Take water vapor, aerosol and droplets to atmosphere ➢ Processed product at up to 5% moisture readily blown: ❑ To silo ❑ To road transport / tanker ❑ To rail transport tanker ❑ Direct to processing plant as feedstock 15 “Low Energy Low Cost Drying For Bulk Materials”

Post Processing Handling & Dispatch ➢ From the filters the ash, when dried to at 0.5 to3% total moisture can be blown to the next phase of handling. ➢ That may be: ❑ Direct to loaders for tanker transport ❑ To storage silo farm ❑ To dry condition storage bunker ❑ To process plant for immediate use ➢ Thamesport facilities are being designed to hold up to 3 days production and to manage to split load types and therefore specific qualities etc to meet client demand - ➢ Primarily EN450 N targeted. 16

Capital Plant Costs Guidance Based upon Thamesport: ➢ To run at 100,000 dry mtpa processing circa 120,000 ➢ Removing circa 15+% Total Moisture for 3% down to 0.5% ➢ Operating 24 hours - 7 days – 48 weeks (8064 hours pa) ➢ Stand-alone energy source CHP + LNG supply contract ➢ Inclusive of Coomtech SMR process plant and associated handling for process storage £2.75 - £3.25m ➢ Design, procure, build and commission ➢ EPC performance underwritten contract ➢ Operating License and Maintenance support 17 “Low Energy Low Cost Drying For Bulk Materials”
