The winter drilling program consisted of fourteen HQ diameter oriented core holes totalling 2,224 meters (7,296 feet). Of these, thirteen holes were drilled in the Yellow Pine deposit area and one at Hanger Flats. Four holes contain significantly higher gold grades than predicted (by the PFS block model) and six holes contain moderately higher gold grades than predicted, and as previously announced, included the best hole ever reported by Midas Gold on the Stibnite Gold Project. In general, antimony grades in the central and southern portions of the Yellow Pine deposit exceeded expectations. "The mineral resource enhancement core drilling program, completed by our team between September 2016 and February 2017, has provided very encouraging results that support Midas Gold's goal of enhancing the mineral resources at the Stibnite Gold Project," said Stephen Quin, President & CEO of Midas Gold Corp. "These results will now be evaluated and, along with additional detailed geological and structural information collected from these and re-logged earlier holes, incorporated into an updated mineral resource for the Yellow Pine deposit in the coming months."

Summary of Program Objectives & Results

As reported on August 23, 2016, the drilling program focused on a number of objectives based on recommendations contained in the 2014 PFS that outlined opportunities that had the potential to enhance Project financial returns, extend Project life and de-risk the projected production. These opportunities included:
1. Better defining the shallow, high grade mineralization in the core of the Yellow Pine deposit;
2. Conversion (through additional drilling) of inferred mineral resources located within the PFS mineral reserve pits into indicated mineral resources and mineral reserves;
3. Conversion (through additional drilling) of inferred mineral resources located outside, but immediately adjacent to, the PFS mineral reserve pits into indicated mineral resources and mineral reserves; and
4. Advancing current prospects that carry no mineral resource at present towards defining mineral resources with the objective of increasing payable gold and Project NPV.

The first two objectives were successfully met and the third and fourth objectives were only partially met as successful drill results in the earlier part of the drill program warranted additional focus in the areas beneath the former open pit at Yellow Pine. Additional drilling may be conducted at a later date to advance all of these objectives, including at the other deposits that comprise the Stibnite Gold Project.

Central Yellow Pine Area

The two most recently completed holes, MGI-17-423 and MGI-17-424, the last holes of the winter program, were completed in the Central Yellow Pine area and the results are reported herein. MGI-17-423 was drilled adjacent to and sub-parallel to holes -414, -421, & -422 (the results for which were previously reported on November 30, 2016 and February 23, 2017), in a broad drill fan, oriented to the southwest to intersect west-northwest and east-west trending, northerly dipping silica-sulphide vein systems and silica-sulphide breccia's at angles appropriate to test true thickness and to validate legacy drill data. Hole MGI-17-423 intersected 194m averaging 2.46g/t Au, 6.3g/t Ag and 0.55% Sb, including 32m averaging 3.04g/t Au, 24.0 g/t Ag and 3.08% Sb. MGI-17-424 was located on a bench in the northwest portion of the historical open pit and was oriented to the southeast at a shallow angle to confirm and expand on gold and antimony mineralization under the historical open pit in an area with little modern era drilling data. The hole intersected 180m averaging 2.5g/t Au, 5.7 g/t Ag and 0.47% Sb. The intercept was slightly shorter, but slightly higher gold grade than the PFS mineral resource estimate. The broad zones of antimony-rich sheeted veins and breccias beneath the former open pit are continuous between holes completed in this program and provide increased confidence in controls on high grade mineralization.

South Yellow Pine Area

Holes MGI-16-418 and MGI-16-419 were drilled in the southeastern portion of the Yellow Pine deposit to follow up on two fences of successful 2012 and 2013 drill holes located to the northeast of 2016 holes MGI-16-418 and MGI-16-419 and successfully cut mineralization (the results of which were previously reported on February 23, 2017). MGI-16-418 returned approximately 30% higher gold grades over an approximately 15% longer width, but with slightly lower antimony grades than anticipated. MGI-16-419 returned gold grades twice those anticipated, but over 60% of the expected width.

Monday Tunnel Area

Two holes, MGI-16-415 and MGI-16-416, were completed in the Monday Tunnel area, located southwest of the southern rim of the former open pit (the results of which were previously reported on February 23, 2017), with MGI-16-415 successfully intersecting the target zone cutting substantially higher grade gold, antimony and silver than predicted from 1940s legacy underground drilling in the area, with the second hole terminated short of the target zone.

Northwest Yellow Pine - Homestake Area

Two holes, MGI-16-411 and MGI-16-412, both intersected significantly higher than anticipated grades as compared to the PFS mineral resource block model and extended a higher-grade trend approximately 100m northeast and remains open along strike (the results of which were previously reported on November 21, 2016).

Northeast Yellow Pine - Homestake Area

A single exploration hole, MGI-16-413, targeted shallower mineralization encountered in adjacent Midas Gold and legacy operator holes in metasediments adjacent to the Meadow Creek Fault Zone. As previously reported on November 21, 2016, this hole intersected quartz veining below the fault but only anomalous gold values were encountered. The complex interaction of structure and stratigraphy in this area make targeting challenging and the potential of this area will be re-evaluated in the future.

Hangar Flats

Hole MGI-16-420 targeted an area of inferred resources on the east flank of the Hangar Flats deposit away from the primary mineralizing structure, the Meadow Creek Fault Zone (the results of which were previously reported on February 23, 2017). The hole, although altered throughout, cut only low grade mineralization, below cut-off grade, averaging 0.21 g/t Au from the collar to the end of the hole.

Sampling Procedures, Quality Control and Quality Assurance

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements set out in National Instrument 43-101 ("NI43-101") and reviewed and approved by Stephen P. Quin, P. Geo., President and CEO of Midas Gold Corp., and a Qualified Person. The exploration activities at the Stibnite Gold Project were carried out under the supervision of Richard Moses, C.P.G., Qualified Person and Field Operations Manager for the Stibnite Gold Project. T&J Enterprises, Inc. of Frenchtown MT was contracted for drilling utilizing an AR-65 core drill with HQ3 core with a diameter of 61.1 mm (2-1/2"). All holes, with the exception of one vertical hole, totaling 101.6 meters (333.3 feet), were drill oriented using an ACT III core orientation tool from International Directional Services; LLC of Chandler AZ. Drilling was conducted 24-hours/day using two shifts each with a 3-person crew (driller, drill helper, mud-man). Shifts were scheduled of 20 days on followed by 10 days off. Core was photographed in the core barrel split inner tube, marked for orientation and discontinuities measured at the drill site and then recovery and RQD were measured, and logged for rock lithology, alteration, mineralization, and structure. The core was boxed, photographed in the core box, with sample intervals selected on approximately 1.52 meter (5 foot) intervals, which were then marked for cutting and sampled. One half the core was collected for assay and the second half retained in the core box for archival purposes.

All gold assays are by a 30g Fire Assay charge followed by an atomic absorption finish (with a 0.005g/t lower reporting limit). Samples reporting values > 6g/t gold are re-analyzed using a 30g Fire Assay charge followed by a gravimetric finish. Silver is analyzed via a 4-acid digestion followed by an ICP finish (with a 0.5g/t lower reporting limit). Samples reporting values > 10g/t silver are reanalyzed using a 50g Fire Assay charge followed by a gravimetric finish. Antimony is analyzed via a 4-Acid digestion with ICP finish with a 5g/t lower reporting limit. Samples reporting values >500g/t antimony are reanalyzed using XRF fusion. Some intervals may not add or subtract correctly due to rounding, but differences are deemed insignificant. Analyses are carried out by ALS Chemex in their Reno and Elko, Nevada and Vancouver, British Columbia laboratories. Umpire samples are routinely submitted to third party labs and blank and standard samples are inserted at appropriate intervals and used for quality assurance and quality control and a review of the results of analyses of the blanks, standards and duplicates by the Company's Qualified Person indicates values are within normal and acceptable ranges.
