Tanya started her career as a keen young geologist, roaming the mosquito-infested forests on Kola peninsula in Russia exploring for nickel, and snow-covered steppes of Northern Kazakhstan, in search for gold. 5 years with BHP Exploration working in Russia, Kazakhstan, and Australia. Then followed 11 years in Canada, working on diamond and gold exploration in Nunavut, base metals in British Columbia, and uranium, coal, and shale gas in Alberta. After moving to the Netherlands Tanya worked in Africa, evaluating opportunities for rutile in Cameron, tin in Rwanda, bauxite in Guinea and iron ore in Tasmania. Until 2019 Tanya worked for Behre Dolbear Minerals Industry Advisors based in Kent, UK. Working with large datasets taught her respect for good data management, so when she heard about blockchain she realized the great potential this technology holds for mining. Tanya now runs independent consultancy focussed on introducing blockchain technology into the mining business.
