As a reminder, historical estimates of resources for the Midwest deposit in Canada, which were done before the adoption of international standards, totaled about 10,000 metric tons of uranium (AREVA’s equity share). This deposit, which has good potential, will require additional work to establish a resource estimate that conforms to international standards.

Significant changes in relation to 2015 (AREVA’s equity share) Aside from the depletion of production, the following changes (AREVA’s equity share) occurred: p a significant increase in resources at the Zoovch Ovoo deposit in Mongolia, with 12,836 metric tons of uranium classified in indicated resources and 60,809 metric tons of uranium classified in inferred resources at December 31, 2016, versus 50,000 metric tons of inferred resources at December 31, 2015.
