“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”.
