The Mineral Resource estimate for the Main and Northeast deposits have an effective date of August 24, 2012, and was supervised and prepared by Independent Qualified Person Mr. Doug Roy, P.Eng. and Mr. Tim Carew, P.Geo., as defined by National Instrument 43-101. Mr. Roy, P.Eng. works for MineTech International Limited (“MineTech”) of Halifax, Nova Scotia, Canada, and Mr. Carew, P.Geo., provided services under contract with MineTech. At the time of the estimate, Mr. Carew worked for Reserva International LLC.

The mineral resource estimate for Getty deposit has an effective date of March 28, 2011 and was supervised and prepared by Independent Qualified Persons Mr. Michael Cullen, P.Geo. and Ms. Chrystal Kennedy, P.Geo. as defined by National Instrument 43-101. At the time of the estimate, both worked for Mercator Geological Services of Dartmouth, Nova Scotia.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, marketing, or other relevant factors. These Mineral Resources are reported using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council. The quantity and grade of reported Inferred Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as an Indicated or Measured Mineral Resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured Mineral Resource category.
