Taking a balanced view

7

Strengths

1. Locations selected for commercial plant can be selected based on political and country risk, not endured due to location of the resource.

2. Feed material is mined and has no risk associated with extraction.

3. Ability of the process to recover a series of metals from feed material reduces commodity risk.

4. Process is scalable and can be converted to run on other feed materials in short order.

5. As plants will generally be constructed on brownfield sites there is considerably less environmental permitting and associated delay.

Weakness 1. As operators recognise the value of the technology cost to secure

feed material will increase.

2. Patents only until 2025 or 2030 - work will be required to maintain new patents as required.

3. Potential Patent infringement will require stringent monitoring.

Opportunities 1. Government financing and grants potential to clean un

historically impacted sites.

2. Opportunity to roll out other parallel business lines not considered in this presentation.

3. Significant 'low hanging fruit' already identified.

4. Low threat of new entrants.

5. Sale of waste product into road building or construction industry.

Threats 1. Patent infringements.

2. Potential environmental liability assumed if historical waste piles are reprocessed - e.g. superfunds often require that the operator not only assumes liability for material processed but also the remediation of the remaining site.

•Minex Process is not 'deposit dependent‘ – it can be located in jurisdictions with low political risk.

• As government agencies have 'inherited' historical slag deposits, favourable terms may be negotiable.

• Clean up / remedial technologies such as the Minex Process are seen in very favourable light by politicians

• There is significant slag volume worldwide allowing Scoria to select the most valuable for reprocessing.

• Significant inorganic growth potential by means of JV's and licence/NSR agreements with metals traders and smelter operators.

•Modular nature – retrofit Brownfields sites that possess prior environmental permitting.

• Potential source of employment in depressed regions improving human capital.

• Significant improvement in environmental capital for stakeholders impacted by large often acid generating slag piles.

• Financial capital improvements in the region from employment and payment of taxes.

• Innovative, but proven technology releasing economic value from something which has previously been considered a liability.

• Ability to select areas to do business ensures legal transparency and judicial security.

• Removing environmental liability from operators balance sheet.

• Improving stakeholders capital by removing visual and other environmental eyesore.

• Entering part of the circular economy, reducing environmental impact from mining operations by generation of a secondary metals source.

The technology Minex Process

9

The Minex Process

A patented process, to economically extract contained metals (precious, base, rare-earth), from smelter slag waste

The Minex Process uses established technology and known chemistry to produce saleable metal products

‘Dry’ Process, no need for dedicated waste storage facility

Use of chloride gas significantly reduces boiling point of metals and hence energy requirement

Discharges a non hazardous waste, reducing smelter / refinery operator environmental liability

Applicable to wide range of solid materials:

Mine waste

Metallurgical and electronic wastes

Complex mineral compounds

The advantages

Single process: Extracts all targeted metals simultaneously and separates the metals using conventional technology

Extensive application: Can be applied to any type of mineralised slag

Low cost: Operating costs are substantially lower than conventional technologies and recoveries significantly higher

Scalable and flexible: The technology can be retrofitted into existing processing plants as well as applied to new facilities

Multiple environmental:

A ‘dry’ process – there is no need to store the discharged waste in environmentally isolated impoundment

Significantly reduces environmental liability, whether it be slag pile management or closure costs

The discharge is non hazardous and can be used in ferro concrete and other cement products

The process requires significantly less energy than other similar technologies

Technology has been materially derisked through comprehensive development with leading international mining consultants 12

Alternative technologies

14

Partial atmosphere roasting

Oxidising leach and solvent extraction for copper slags

Acid fuming and precipitation of zinc slags

Grinding and separation by air or other processes of ferrous or other waste

All face challenges to effectively extract metals and manage process discharge either due to cost or technical limitations

The Minex Process has none of these disadvantages and is the best solution for cost effective metals recovery
