Qualified Persons and Technical Disclosure Statement

Scott Heffernan, M.Sc., P.Geo., the Company’s EVP Exploration and Qualified Person under National Instrument 43-101 (“NI 43-101”), has reviewed and verified that the technical information contained in this news release is accurate and approves the written disclosure of this information.

Aurizona: The 2018 Piaba open-pit, Piaba underground and Boa Esperança open-pit resource estimates, with an effective date of October 22, 2018, were prepared by Trevor Rabb, P.Geo (EGBC #39599), B.Sc., who is a “qualified person” within the meaning of NI 43-101. Mr. Rabb is an employee of Equity Exploration Consultants Ltd. and is considered to be “independent” for the purposes of Section 1.5 of NI 43-101. The Aurizona reserve estimate was disclosed in the “Feasibility Study on the Aurizona Gold Mine Project” prepared by Lycopodium Minerals Canada Ltd. with an effective date of July 10, 2017, which is available for download on SEDAR at www.sedar.com. The Mineral Reserve estimate has an effective date of May 29, 2017 and is based on the Mineral Resource estimate dated January 5, 2017 and prepared by SRK Consulting (Canada) Inc. The Mineral reserve calculation was completed under the supervision of Gordon Zurowski, P.Eng of AGP, who is a Qualified Person as defined under NI 43-101. Mineral Reserves are stated within the final design pit based on a $1,056 per ounce gold price pit shell with a $1,200 per ounce gold price for revenue. The cutoff grade was 0.60 g/t Au for the Piaba pit area and 0.41 g/t Au for the Boa Esperança area. The mining cost averaged $2.32/tonne mined, processing averages $11.30/tonne milled and G&A was $2.84/tonne milled. The process recovery averaged 90.3%. The exchange rate assumption applied was R$3.30 equal to US$1.00. Numbers may not sum due to rounding.

Mesquite: The Mesquite reserve and resource estimates were disclosed in the technical report entitled “Technical Report on the Mesquite Gold Mine, Imperial County, California, U.S.A.” prepared by AGP with an effective date of December 31, 2018, which is available for download on SEDAR at www.sedar.com. The Mesquite resource estimate was prepared by Robert Sim P.Geo, SIM Geological Inc. and Bruce Davis, FAusIMM, BD Resource Consulting, Inc. The Mesquite reserve estimate was based on the Mesquite mineral resource estimate prepared by SIM Geological Inc. The mineral reserve calculation was completed under the supervision of Gordon Zurowski, P.Eng of AGP, who is a Qualified Person as defined under NI 43-101. The estimated mineral resources represent the material located between the surveyed topographic surface at December 31, 2018 and the ultimate resource limiting pit shell generated at year-end 2018, excluding any surface stockpiles, and are reported exclusive of mineral reserves. Cut-off grade for oxide material is 0.134 g/t Au and 0.288 g/t Au for transition and non-oxide material. The reserves for Mesquite are based on the conversion of the Measured and Indicated resources within the current mine plan. Measured Resources are converted to Proven Reserves and Indicated Resources are converted directly to Probable Reserves. Mineral reserves are stated within the final design pit based on a $1,250/oz gold price. The cut-off grade for oxide material is 0.15 g/t and 0.31 g/t for transition and non-oxide material. The mining cost averaged $1.45/t mined, processing costs are $1.81/t ore and G&A was $0.75/t ore placed. The ore recoveries were 75% for oxide, and 35% for transition and non-oxide material. Numbers may not sum due to rounding.

Castle Mountain: The Castle Mountain Mineral Reserve and Mineral Resource Estimates were disclosed in the “NI 43-101 Technical Report on the Preliminary Feasibility Study for the Castle Mountain Project” prepared by Kappes, Cassiday and Associates with an effective date of July 16, 2018, which is available for download on SEDAR at www.sedar.com. The Mineral Reserve estimate with an effective date of June 29, 2018 is based on the Mineral Resource estimate with an effective date of March 29, 2018 that was prepared by Don Tschabrun, SME RM of Mine Technical Services. The Mineral Reserve was estimated by Global Resource Engineering, LLC with supervision by Terre Lane, MMSA, SME RM. Mineral Reserves are estimated within the final designed pit which is based on the $850/oz pit shell with a gold price of $1,250/oz. The minimum cut-off grade was 0.14 g/t gold and 0.17 g/t gold for Phases 1 and 2, respectively. Average life of mine costs are $1.39/tonne mining, $2.11/tonne processing, and $0.80/tonne processed G&A. The average process recovery was 72.4% for ROM and 94% for Mill/CIL. The Mineral Resource is based on a gold cut-off grade of 0.17 g/t. The Mineral Resource is contained within an LG shell limit using a $1,400 gold price as well as cost and recovery parameters presented in the technical report. Numbers may not sum due to rounding.

Elk Gold: The Elk Gold Mineral Resource estimate has an effective date of August 22, 2016 as reported in the “Technical Report on Resources of the Elk Gold Project” completed by Robert Wilson, P.Geo., Gary Giroux, P.Eng. and Antonio Loschiavo, P.Eng. with an effective date of August 22, 2016. The Mineral Resource calculation was completed under the supervision of Gary Giroux, P.Eng., who is a Qualified Person as defined under NI 43-101. The constrained resource was calculated using a gold price of US$1232/oz. Open-pit resources are reported at a 1.0 g/t gold cut-off grade and potential underground resources are reported at a 5.0 g/t cut-off grade. The grade reported is the average grade of the resource both in and underground. Numbers may not sum due to rounding.

Estimates of Measured, Indicated and Inferred Mineral Resources

Information regarding reserve and resource estimates has been prepared in accordance with Canadian standards under applicable Canadian securities laws and may not be comparable to similar information for United States companies. The terms “Mineral Resource”, “Measured Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” used in this news release are Canadian mining terms as defined in accordance with NI 43-101 under guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Standards on Mineral Resources and Mineral Reserves adopted by the CIM Council on May 10, 2014. While the terms “Mineral Resource”, “Measured Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” are recognized and required by Canadian regulations, they are not defined terms under standards of the United States Securities and Exchange Commission. Under United States standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve calculation is made. As such, certain information contained in this news release concerning descriptions of mineralization and resources under Canadian standards is not comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the United States Securities and Exchange Commission. An “Inferred Mineral Resource” has a great amount of uncertainty as to its existence and as to its economic and legal feasibility. It cannot be assumed that all or any part of an “Inferred Mineral Resource” will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. Readers are cautioned not to assume that all or any part of Measured or Indicated Resources will ever be converted into Mineral Reserves. Readers are also cautioned not to assume that all or any part of an “Inferred Mineral Resource” exists or is economically or legally mineable. In addition, the definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” under CIM standards differ in certain respects from the standards of the United States Securities and Exchange Commission.
