Pilot Gold Inc. ("Pilot Gold" or the "Company") is pleased to announce additional drill results from 6 Reverse Circulation (RC) and 4 diamond core holes at the 100% controlled Goldstrike Oxide Gold Project in southwestern Utah. The primary target is Carlin-style shallow, oxide gold mineralization on the 7 km long, 2 km wide "Historic Mine Trend", between and down-dip to the north of historic open pits.
Highlights from infill and step-out drilling include:
- 0.87 grams per tonne gold (g/t Au) over 45.4 metres (m) in PGS046C - core hole
- 0.76 g/t Au over 67.1 m in PGS053, including 1.91 g/t Au over 6.1 m
- 2.24 g/t Au over 58.8 m in PGS054C, including 2.77 g/t Au over 36.2 m, including 6.04 g/t Au over 3.0 m - core hole
- 0.96 g/t Au over 76.2 m in PGS058, including 1.98 g/t Au over 19.8 m
- 0.46 g/t Au over 29.5 m in PGS059CA - core hole
- 0.52 g/t Au over 25.9 m and 0.42 g/t Au over 25.9 m in PGS064
Nine of the ten released holes contain reportable oxide gold intercepts. The mineralized intercept in drill hole PGS054C is a follow-up to PGS026, which returned 57.9 m grading 1.19 g/t Au (see press release dated April 12, 2014), PGS027, which returned 47.2 m grading 1.14 g/t Au (see press release dated May 10, 2016) and PGS51C, which returned 41.1 m grading 2.64 g/t Au (see press release dated June 17, 2016). This is a new zone of mineralization down-dip of a historic surface showing and demonstrates the potential for discovery of higher-grade and more extensive mineralization in the shallow subsurface.
- Continued drilling of the main gold host horizon, the Claron Formation, has resulted in the discovery of new areas with high grade feeder structures, including mineralization encountered in PGS058. A more concentrated RC drill pattern will be used to define these mineralized zones.
- Continued drilling to date confirms gold mineralization with significant width and grade over virtually the entire Goldstrike Graben over an east-west distance of 1.4 km by 200 to 400 m north-south.
- An additional 30 drill holes are proposed within this area before extending the infill step-out drill program up to 4.5 km to the west and 1 km to the east following the historical mine trend.
- New drill intercepts indicate the possibility of thicker zones of mineralization in newly-tested areas, with some intercepts, including PGS058, of up to 76 m drilled thickness.

Mineralization in most holes is strongly oxidized, with AuCN assays typically between 70% and 100% of conventional fire assays.

RC drilling is ongoing, with on average 5 RC drill holes completed per week.
Goldstrike is located in the eastern Great Basin, immediately adjacent to the Utah/Nevada border, and is a Carlin-style gold system, similar in many ways to the prolific deposits located along Nevada's Carlin trend. Like Kinsley Mountain and Newmont's Long Canyon deposit, Goldstrike represents part of a growing number of Carlin-type systems located off the main Carlin and Cortez trends in largely underexplored parts of the Great Basin. The Goldstrike Property comprises 96 km2 of US federal lode claims, patented (private) claims and Utah State leases. Previous mining at Goldstrike(1) occurred from 1988 to 1994, with 209,000 ounces of gold produced from 12 shallow pits, at an average grade of 1.2 g/t Au.

Moira Smith, Ph.D., P.Geo., Vice-President Exploration and Geoscience, Pilot Gold, is the Company's designated Qualified Person for this news release within the meaning of National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and has reviewed and validated that the information contained in the release is accurate. Drill composites were calculated using a cut-off of 0.20 g/t. Drill intersections are reported as drilled thicknesses. True widths of the mineralized intervals are interpreted to be between 30-90% of the reported lengths. Drill samples were assayed by ALS Limited in Reno, Nevada for gold by Fire Assay of a 30 gram (1 assay ton) charge with an AA finish, or if over 5.0 g/t were re-assayed and completed with a gravimetric finish. For these samples, the gravimetric data were utilized in calculating gold intersections. For any samples assaying over 0.200 ppm an additional cyanide leach analysis is done where the sample is treated with a 0.25% NaCN solution and rolled for an hour. An aliquot of the final leach solution is then centrifuged and analyzed by AAS. QA/QC for all drill samples consists of the insertion and continual monitoring of numerous standards and blanks into the sample stream, and the collection of duplicate samples at random intervals within each batch. Selected holes are also analyzed for a 51 multi-element geochemical suite by ICP-MS. ALS Geochemistry-Reno is ISO 17025:2005 Accredited, with the Elko prep lab listed on the scope of accreditation.
Goldstrike is an early-stage exploration project and does not contain any mineral resource estimates as defined by NI 43-101, except for that which is noted in a NI 43-101 technical report prepared for a previous operator entitled, "Technical Report on the Mineral Mountain Property, Washington County, Utah, USA", dated February 16, 2010, prepared by Kenneth P. Puchlik, of Puchski GeoConsultants, a "Qualified Person" as defined by NI 43-101. The potential quantities and grades disclosed herein are conceptual in nature and there has been insufficient exploration to define a mineral resource for the targets disclosed herein. It is uncertain if further exploration will result in these targets being delineated as a mineral resource.
