The Inferred Resources are in addition to the Measured and Indicated Resources. 2. The Mineral Resources have been classified in accordance with requirements of NI 43- 101 and the CIM standards. Resource estimates were based on a gold price of USD$1,350 per ounce and a 93% recovery. 3. Mineral Resource Estimation Summary Report, prepared as of Dec 31 st 2012, by Kevin Harris, Internal Resources Estimate, under supervision of Richard Allan P.Eng., qualified person, not independent from End eavour. 4. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. 5. “UG” stands for underground and “OP” stands for open pit. Mineral Reserves Estimate The Mineral Reserves estimate for the Tabakoto Project demonstrates several sources of open pit and underground Mineral Reserves that are projected to provide flexibility for Endeavour’s mining plans. The Corporation is currently transitioning from an open pit mining operation to a primary underground mining operation with open pit mining providing contingency mill feed. The Mineral Reserve estimate as of December 31, 2012 is as follows: Table 2.
