Winnipeg, Manitoba, to the west.

The current drill program is wholly funded by Pioneer as part o f its earn -in on the Mavis Lake

Project (see Company news release dated March 14, 2016).

located within the renowned South American “Lithium Belt” that is the host to the vast majority of

global lithium resources, reserves and production. The Mariana project strategically

encompasses an entire mineral rich evaporite basin, totaling 160 square kilometres that ranks

as one of the more prospective salars or ‘salt lakes’ in the region. Curren t ownership of the

project is through a joint venture company, Litio Minera Argentina S. A., a private company
