George Annandale, , a world-renowned vanadium expert, 30 years of international experience and consultant to the Company, said, "Armed with the promising results from the metallurgical test work conducted by SGS Lakefield, I am confident that we will be able to optimize the conditions of the pre-roast and alkaline pressure leaching process to further enhance the economics of the project. The Green Giant project is well on its way to becoming one of the world's largest producers of vanadium., George added that, "The alkaline
pressure leach process which resulted in up to 82% vanadium extraction is
a well-established and proven technology that is in use today, in
particular, in connection with the treatment of uranium ores."

The 2011 metallurgical program being carried out at SGS Lakefield is being directed by George Annandale.

WHO is this George guy and what does he know anyways?

Balla Balla Vanadium Project – July 1999 to June 2000

Contracted by Thiess Contractors as consultant to oversee and review the design, construction and commissioning of a 6000 tpa Vanadium recovery facility to produce fused flake from a titaniferous magnetite containing 0.75% V2O5. Process covers the mining , beneficiation and recovery of the vanadium. The vanadium recovery includes roasting with a kiln to solubilise the vanadium, leaching, counter current washing, precipitation , calcining and fusion of the vanadium. Also included are the environmental issues and infrastructure.


Process and Mining Consultants (PMC) - January 1988 to January 1989

Designed a V2O5 facility. This was on the same scale as the Balla Balla facilty. This was done for a feasibility study but has not progressed to project status yet.

Built and commissioned 2 minor gold processing plants, one in Nelspruit and one in Pelgrimsrust, processing 100 000 and 200 000 tonne/month ore. The Nelspruit unit recovered gold via CIL/carbon elutriation/bullion production. It also incorporated a carbon regeneration facility.

African Exploration - January 1987 to July 1987

Designed the process for this V2O5 facility for African Exploration. The facility was built and commissioned by IMS. Consequently IMS used this information and their experience at Vantech to build the Rhovan facility as well.

Rhombus-Rhovan August 1989 and again in July 1990

Did a due diligence on Rhovan process for USCO. Also reviewed the Rhovan design for Lurgi when they submitted a tender to design and build the Rhovan Facility. They lost the bid to IMS.


Van Eck and Lurie: January 1982 to December 1983

Was responsible for managing the design and proposals for minerals processing plants as the Marketing Manager. All Process design engineers reported to the Marketing Manager, who also carried the process design responsibilities.

During this period various coal washing and diamond recovery plants were tendered for successfully. Of note is the following project:

Optimum Colliery.

A Project with General Mining for a Coal Washing Plant of 2000 tonne/hr was designed, constructed and commissioned in 21 months.

The project started with inpit crushing, overland conveyor with stackers and reclaimers feeding a coal washing facility with 3 parallel drum and cyclone washing modules. The fines were filtered with belt/drum filters. The high purity coal was exported through a rapid load-out facility. The middlings were used for power station feed in a 6x100MW power station and waste was discarded.

The plant was commissioned in 4 months from pre-commissioning to 100 % of design.

Union Carbide : September 1970 to December 1981

Production Superintendent – January 1971 to August 1972

. Converted an existing V2O5 facility from a 1.5 million lbs/yr to 3.5 million lbs/yr by debottle necking.

. Erected a forced circulation double effect evaporation plant to treat the effluent. The process developed recovered the sodium sulphate to recycle to the roast circuit and ammonium sulphate to recycle to the precipitation circuit. This turned the process into a zero discharge facility.

. Constructed and commissioned a Vanadium Carbide and Vanadium Nitride facility from research data developed by the Union Carbide Niagara Falls Research Facility.

Project Manager – September 1972 to December 1973

. Identified and developed process to upgrade ore from 0.7 to 2.1 % V2O5 with laboratory scale equipment.

. Designed, built and commissioned a crushing and milling facility with van Eck and Lurie to provide the upgraded feed to the Pretoria facility.

Technical Manager - January1974 to April 1975.

Transferred to Hot Springs, Arkansas to resolve bottlenecks and mining related problems at the 12 million lbs / year Vanadium facility at Hot Springs, Arkansas.

Project Manager – April 1975 to February 1976

. Designed, built and commissioned new facility, to produce 12 million lbs. V2O5/annum at the Brits mines location, based on laboratory scale operation.

. The process started with crushing, screening, milling and magnetic separation to provide clean titaniferous magnetite to the kiln. The 4mD x 80m long kiln are heated to 1250oC with sodium carbonate and sodium sulphate mixed into the magnetite.

The solubilised vanadium is leached and washed in a counter current wash circuit. The vanadium rich solution is filtered; ammonium sulphate is added to precipitate the vanadium. The precipitant is filtered, calcined and fused to produce the final product.

The effluent is evaporated to recover the excess ammonium and sodium sulphate for re-use.

. Van Eck & Lurie was the main contractor. The plant was built and commissioned in 18 months. The facility covers 15 hectares and included mining, all infrastructure and reagent handling.

. Commissioning to full-scale production took 6 months.

General Manager – February 1976 to December 1977

Managed the above facilities including the Pretoria works. Produced 17.5 million lbs./annum V2O5 as fused flake, carvan or nitrovan.
