Hugo, an Argentine national, was instrumental in identifying U3O8 Corp's principal uranium projects in Colombia and Argentina and in assembling the technical team that has contributed to the company having one of the most advanced uranium portfolios in South America. He has been promoted to Executive Vice President to assume a more strategic role with specific responsibilities for management of relationships with local communities, to continue to drive U3O8 Corp's environmental and health and safety initiatives and to lead its interaction with provincial and central governments. Hugo has 29 years' mining industry and exploration experience including senior roles as Exploration Manager for Argentina Gold Corporation and Business Manager of Mt. Isa Mines Ltd. in Argentina and South America.

'We are delighted to have Gabriel, Elpidio and Hugo take on key roles to advance our projects through exploration to resource definition and to subsequent reserve estimation, scoping and feasibility studies,' said Dr. Richard Spencer, U3O8 Corp's President and CEO. 'Gabriel brings technical experience to execute on our aggressive exploration programs in Colombia, Guyana and Argentina. With our plans for rapid resource growth this year, Elpidio's expertise will help position the Berlin Project in Colombia and the Kurupung Project in Guyana for scoping studies and, in addition, he is tasked with refining the beneficiation process on the low-grade Laguna Salada Project in Argentina. Hugo's leadership in establishing and maintaining support from local communities and developing positive government relations will continue to be key priorities to ensure that our projects continue on a path of excellent social and environmental stewardship.'
