Advanced Mineral Recovery Technologies, (AMRT Ltd.) is an authorised & licensed operating company utilising the Advanced Mineral Recovery Technologies (“AMRT”) patented process. Some of the shareholders of IMS are also shareholders in AMRT. AMRT has a proprietary technology for treating the waste streams from mining and smelting operations whereby the valuable metal content is recovered while the potentially hazardous waste is converted to an environmentally-inert slag. The technology is broadly applicable: virtually all mining & smelting works creates waste in the form of dust, fines or slag.

The AMRT Technology & Process
The AMRT Mineral Recovery Process utilizes a patented
AC electric arc furnace/smelter technology uniquely
suited to profitably solve environmental and
sustainability problems in the metals industries in the
new century.
The Process
◦ Efficiently extracts valuable metals from a wide variety of
feedstocks
◦ Addresses significant toxic waste problems, turning liabilities into
profit-making assets
◦ Has low breakeven points (furnace size & commodity price)
◦ Can directly process “fines” and other problematic materials
without intermediate steps
◦ Ideally suited for local empowerment
◦ Energy efficient

Basic process patent granted in UK:
◦ UK Patent GB 2430276B “Control System for an Arc Furnace” granted
September 16, 2009 runs to 9/19/2025
◦ Protected in over 30 other countries
◦ Additional patent issued for treatment of bauxite residue (“Red Mud”)
used in successful demonstration funded by the European Commission
Patented Process Technology is based on:
◦ A proprietary thermo-dynamic model which produces an accurate mass
and energy model to predict how the process should be applied
◦ Proprietary software implemented in a digital programmable logic
controller (‘PLC’) used to control the operation of the furnace

treatment of waste from aluminum production.
Applications Test Furnace operated at Jet Park in
Johannesburg, RSA for 2+ years
 Over 3,000 successful test melts on wide variety of materials
 Independent “Process Audits” by universities and independent
experts, sale of products on commercial terms during tests
Test Furnace located at major copper mine in Zambia
demonstrated 97%+ extraction of trace gold from copper
tailings.
◦ Tests independently audited by SGS Inspection Services Limited.
*Kilo Volt Amperes (KVA) and Mega Volt Amperes (MVA) are typical units for
describing the size of electric furnaces, similar to electrical transformers. To a
reasonable approximation, a 1000 KVA or 1 MVA furnace requires 1000
kilowatts (kW) or equivalently 1 megawatt (MW) of electric power.

Basic Steps in Assessing Applications
 Step 1: Obtain raw material chemical analysis (chemical
concentrations in %)
◦ Protected as required by NDAs
 Step 2: Run Patented Mass-Energy Balance Analysis (time needed:
2 days)
◦ Paper projection of results of “recipe”
 Input materials  furnace  output (metal + slag + volatiles)
 Step 3: Run material sample through WT Pilot Scale Test Furnace
(3-5 days processing)
◦ Repeat runs as needed to optimize process results
 Step 4: Obtain “Process Audit” by independent testing firm
◦ Obtain lab analysis of output (metal + slag + volatiles)
◦ Record process parameters (kWh use, reactants, emissions, etc.)
◦ Validates yields, process economics suitable for bank due diligence
 Step 5: Develop plan for commercial operations

Bauxite
Residue
 Bauxite residue – or ‘Red Mud’ – is produced during the
production of alumina from Bauxite using the Bayer Process
invented in 1888
 Bauxite residue is a high-volume hazardous waste which is typically
stockpiled or dumped with little or no treatment
 Approximately 100 million tons/yr being produced without an
economical or environmentally sustainable solution.

AMRT and the European Commission co-funded two
furnaces in Greece as part of the ENEXAL Program to
demonstrate treatment of bauxite residue (Red Mud):
◦ A 400 kVA furnace installed and operated with the National Technical
University of Greece (NTUA) at Ypato, 60 miles north of Athens
(commissioned 2011)
◦ A 1 MVA furnace installed at the plant site of Aluminium of Greece
about 60 miles west of the NTUA site (commissioned 2012)
The Program has demonstrated that pig iron and mineral
wool for industrial insulation can be produced from Red
Mud using the Process furnace technology and commercial
fiberization equipment.

 A major copper mine in Zambia is producing tailings containing an
average of 4.5% copper and 50-400 ppm gold.
 Analyses of technologies for recovering the gold indicated
inadequate recoveries or high costs, leading the company to
stockpile the tailings under guard for possible future solution.
 AMRT, and mine owner agreed to move a 650 KVA test furnace to
Zambia to test recoveries.
 Results independently observed and tested by SGS Inspection
Services Limited (SGS), a noted mineral testing firm.
 Tests indicated a 97% overall gold recovery in matte form suitable
for final refining into pure metal.
