Following is the estimate for an in-pit resource utilizing a cut-off grade of 0.4 g/t gold:

Note: Mineral resources are not ore reserves and do not have demonstrated economic viability. All figures rounded to reflect the relative accuracy of the estimates. Metal assays were capped where appropriate. Mineral Resources are reported based on a CoG of 0.4 g/t Au, and are reported inside a conceptual pit shell based on appropriate mining and processing costs and metal recoveries for oxide and sulfide material.CoGs are based on a mining cost of US$1.50/t, milling cost of US$15/t, administration cost of US$1.00/t, a gold price of US$1,300/oz., 90% gold recovery, gold refining cost of US$8/oz, and 5% NSR royalty.

The updated resource estimates will support the completion of a Preliminary Economic Assessment (“PEA”) on the Montagne d’Or deposit on target to be completed in approximately one month. The work is being funded by Nord Gold N.V. (LSE: NORD LI) as part of a minimum US$30 million exploration and development program pursuant to which they can earn a 50.01% interest in Montagne d’Or and the Paul Isnard mineral claims, by completing a bankable feasibility study no later than March 2017.
