Forward Looking Statements

Mineral ResourcesThis Presentation contains information regarding mineral resources estimated at the projects of the companies referenced herein. Mineral resources arenot mineral reserves and do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental,permitting, legal, title, socio-political, marketing or other relevant issues. In particular, the quantity and grade of reported inferred mineral resources inthe estimates referenced in this Presentation are uncertain in nature and there is insufficient exploration to define these inferred mineral resources as anindicated or measured mineral resource in all cases. It is uncertain in all cases whether further exploration will result in upgrading the inferred mineralresources to an indicated or measured mineral resource category.

For details regarding the key assumptions, parameters and methods used to estimate the mineral resources presented in respect of the Windfall Lakeproject, please see the "Technical Report for the Windfall Lake Gold Project, Quebec" dated April 17, 2014 (effective date March 3, 2014) filed onwww.sedar.com under the company profile of Eagle Hill Exploration Corporation. Please note that the Windfall Lake PEA (as defined below) is based ona mineral resource estimate with an effective date of November 13, 2014.

For details regarding the key assumptions, parameters and methods used to estimate the mineral resources presented in respect of the Whitney project,please see the "Technical Report and Resource Estimate on the Upper Hallnor, C-Zone, and Broulan Reef Deposits, Whitney Gold Property, TimminsArea, Ontario, Canada" dated February 27, 2014 filed on www.sedar.com under the company profile of Temex Resources Corp.

For details regarding the key assumptions, parameters and methods used to estimate the mineral resources presented in respect of the Juby project,please see the "Technical Report for the Juby Gold Project, Ontario" dated and effective February 26, 2014 filed on www.sedar.com under the companyprofile of Temex Resources Corp.

Preliminary Economic AssessmentThe preliminary economic assessment of the Windfall Lake project (the "Windfall Lake PEA") is preliminary in nature and includes inferred mineralresources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to becategorized as mineral reserves, and there is no certainty that the Windfall Lake PEA will be realized.

Qualified PersonThe technical information contained in this Presentation has been reviewed and approved by Gernot Wober B. Sc., P. Geo., a Qualified Person withinthe meaning of NI 43-101.
