• Keeping transportation traffic to a minimum by: – Locating some work functions offsite at SGLF – Consolidation of freight offsite at SGLF – Locating camp at Project site (mostly 14 day rotations) – Using vans/buses to transport employees & contractors – Primarily weekday transports in 6am-8pm time period

• Maintaining strict materials and supplies handling policies at site & for transport: – No reportable spill on site for five years – No spill ever while transporting fuel/consumables to site

EXPLORATION Ch. 13 of the PRO

57 Existing Deposits:

• Resource to reserve conversion • Resource/reserve expansion immediately adjacent to pits • In pit unclassified materials • Grade &/or oz increases in historic data areas

Priority Prospects: • Small tonnage, high grade

e.g. Garnet, Scout, Upper Midnight • Bulk tonnage

e.g. Cinnamid-Ridgetop, Saddle-Fern, Rabbit • Undefined airborne targets

e.g. Mule, Salt & Pepper, Blow-out

• Many prospects remain that warrant further exploration • Surface exploration drilling method:

– Appropriate drilling equipment & methods previously employed & approved – New drill site footprints kept to minimum:

• Whenever practical, sited on historical disturbance – Concurrent reclamation – Water & non-toxic approved drilling fluids used for all drilling

• Underground exploration drilling: – To access mineralized zones inaccessible by surface exploration methods – For evaluation of the Scout prospect

REGULATORY INFORMATION

The technical information in this presentation (the “Technical Information”) has been approved by Stephen P. Quin, P. Geo., President & CEO of Midas Gold Corp. (together with its subsidiaries, “Midas Gold”) and a Qualified Person. Midas Gold’s exploration activities at Stibnite Gold were carried out under the supervision of Christopher Dail, C.P.G., Qualified Person and Exploration Manager and Richard Moses, C.P.G., Qualified Person and Site Operations Manager. For readers to fully understand the information in this presentation, they should read the Pre-Feasibility Study Report (available on SEDAR or at www.midasgoldcorp.com) in its entirety (the “Technical Report”), including all qualifications, assumptions and exclusions that relate to the information set out in this presentation that qualifies the Technical Information. The Technical Report is intended to be read as a whole, and sections or summaries should not be read or relied upon out of context. The technical information in the Technical Report is subject to the assumptions and qualifications contained therein. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. These mineral resource estimates include inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these Inferred mineral resources will be converted to the Measured and Indicated categories through further drilling, or into mineral reserves, once economic considerations are applied. Section 2.3 of NI 43-101 states that: Despite paragraph (1) (a), an issuer may disclose in writing the potential quantity and grade, expressed as ranges, of a target for further exploration if the disclosure

(a) states with equal prominence that the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resource; and (b) states the basis on which the disclosed potential quantity and grade has been determined.

The mineral resources and mineral reserves at the Stibnite Gold Project are contained within areas that have seen historic disturbance resulting from prior mining activities. In order for Midas Gold to advance its interests at Stibnite, the Project will be subject to a number of federal, State and local laws and regulations and will require permits to conduct its activities. However, Midas Gold is not aware of any environmental, permitting, legal or other reasons that would prevent it from advancing the project. The PFS was compiled by M3 Engineering & Technology Corp. (“M3”) which was engaged by Midas Gold Corp.’s wholly owned subsidiary, Midas Gold Idaho, Inc. (“MGII”), to evaluate potential options for the possible redevelopment of the Stibnite Gold Project based on information available up to the date of the PFS. Givens Pursley LLP (land tenure), Kirkham Geosystems Ltd. (mineral resources), Blue Coast Metallurgy Ltd. (metallurgy), Pieterse Consulting, Inc. (autoclave), Independent Mining Consultants Inc. (mine plan and mineral reserves), Allen R. Anderson Metallurgical Engineer Inc. (recovery methods), HDR Engineering Inc. (access road), SPF Water Engineering, LLC (water rights) and Tierra Group International Ltd. (tailings, water management infrastructure and closure) also contributed to the PFS. Additional details of responsibilities are provided at the end of this news release and in the technical report filed on SEDAR in December 2014. The PFS supersedes and replaces the technical report entitled ‘Preliminary Economic Assessment Technical Report for the Golden Meadows Project, Idaho’ prepared by SRK Consulting (Canada) Inc. and dated September 21, 2012 (PEA) and that PEA should no longer be relied upon.

"Cash Costs", “All-in Sustaining Costs” and “Total costs” are not Performance Measures reported in accordance with International Financial Reporting Standards (“IFRS”). These performance measures are included because these statistics are key performance measures that management uses to monitor performance. Management uses these statistics to assess how the Project ranks against its peer projects and to assess the overall effectiveness and efficiency of the contemplated mining operations. These performance measures do not have a meaning within IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.
