:: Newlox Gold Ventures and Argo Applied Technologies to Develop Ground-Breaking Clean Gold Production Technology


Newlox Gold Ventures Corp. is pleased to announce that it has signed a Pilot Plant development contract with Argo Applied Technologies, the British natural resources technology company to develop and deploy cutting-edge clean gold production technology.

This partnership follows-up on significant research and development which has taken place over the past year at the University of Leicester, where samples collected from Newlox’s projects in Central America have been used to evaluate innovative and environmentally positive mineral recovery technologies in a laboratory setting.

Argo and Newlox are now endeavouring to apply this ground-breaking technology to the mineral processing field. Research completed over the past year has yielded very encouraging results and provides a solid foundation for Argo to build upon and commercialize.

Argo’s DESion™ technology is based on the use of Deep Eutectic Solvents, developed at the University of Leicester, to process mineral ores. DESion™ presents a non-toxic, environmentally safe, processing option for the recovery of precious metals and mercury from Newlox’s feed material. Initial testwork completed by Argo has already indicated the potential for the very rapid dissolution of both gold and mercury by DESion™, and faster than the industry standard leaching technologies available today.

The ability of Deep Eutectic solvents to dissolve and selectively recover virtually any metal while requiring no water and no toxic processing inputs is a paradigm shift for the industry. The Deep Eutectic Solvents technology underlying DESion™ was first utilised in the aerospace industry twenty years ago to recycle superalloy metals. Argo is now applying this technology to the metals & mining sector.

The contract is to be executed in phases to perform the required laboratory test work to enable construction of a Pilot Plant suitable to process the artisanal gold tailings feed from Newlox’s projects. The primary target of the Pilot Plant is to evidence that Argo’s DESion™ technology process provides a commercially and environmentally superior alternative to current industry standards and could benefit Newlox’s current planned project design in relation to the processing artisanal gold tailings.

“We are very excited by this development opportunity with Argo Technologies, and Argo’s philosophy fits in with Newlox’s own strategy of recovering gold through socially and environmentally responsible processes recovering contaminants and residual precious metals from historical waste. Argo’s initial results testwork, especially in relation to the potential recovery of mercury and the rate of recovery of gold has prompted Newlox to work with Argo,” commented Ryan Jackson, President of Newlox Gold.

“Applying Deep Eutetic Solvents to the global mining industry is a core objective of Argo. We are very pleased to be able to announce this contract and the wider collaboration that we will undertake with Newlox Gold as a customer. Reducing the environmental and social impacts of mining is a core advantage for mining companies using DESion™ rather than conventional metals processing techniques,” commented John Murray, Director, Argo Applied Technologies.
