“I was impressed with the skills, capabilities and experience of the XPS staff, and they clearly have the capabilities to perform the work program identified effectively.“

— John Marsden, President, Metallurgium

“The specialist service provided by Dominic and his group at XPS is top quality. I do not know of any facility that can combine disciplines of mineral science and metallurgy with a strong overlay of high confidence methodology in the way that he and his colleagues can. I have no hesitation in recommending him”.
