Pilot Gold Inc. ("Pilot Gold" or the "Company") is pleased to announce drill results from an additional 7 Reverse Circulation (RC) drill holes in the Main Zone of the 100% controlled Goldstrike Gold Project in southwestern Utah. The primary target is shallow Carlin-style, oxide gold mineralization within the 14 km2 "Historic Mine Trend", between and down-dip of historic open pits.
Current drill highlights include:
- 0.90 grams per tonne gold (g/t Au) over 12.2 metres (m) in PGS099
- 1.06 g/t Au over 10.7 m and 0.60 g/t over 6.1 m in PGS100
- 0.51 g/t Au over 27.4 m in PGS101
- 0.44 g/t Au over 6.1 m and 0.49 g/t Au over 18.3 m in PGS102
- 0.60 g/t Au over 13.7 m in PGS103
- 0.86 g/t Au over 67.1 m including 2.35 g/t Au over 15.2 m and 0.74 g/t over 10.7 m in PGS104
- 0.44 g/t Au over 32.0 m and 0.43 g/t Au over 21.3 m in PGS105
All 7 holes intersected notable widths grading between 0.44 and 2.35 g/t Au.
- RC drilling has concluded in the Main Zone (located on the eastern end of the Historic Mine Trend) to prepare it for inclusion in a resource estimate, projected for completion in Q1 2017.
- 22 Main Zone drill holes are currently pending assay results.
- A second drill rig was mobilized to the property on September 15.
- One rig has begun drilling on the Peg Leg graben target, a sub-parallel structure to the Goldstrike Graben located southwest of the main zone. Fourteen drill sites are permitted in this area, which extends over a distance of 1.5 km x 250 m.
- The second drill rig is being mobilized to the "Dip Slope" zone, located to the north of the main zone in the footwall of the Hassayampa fault. This area hosts the historic Hassayampa, Goldtown and Padre pits, with unmined gold intercepts in historic holes throughout the area.

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. 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.

GOLDSTRIKE PROJECT, UTAH - METALLURGICAL UPDATE
Cyanide soluble test results from the metallurgical core holes were released on August 4, 2016 and most holes contain oxide gold with a very high percentage of cyanide soluble gold. Eight out of the ten core holes returned an average of 88.4% cyanide solubility.
Bottle rolls results, which will provide information necessary to design and cost a potential gold processing circuit, are anticipated to be received and released to the market by the end of October 2016.
BLACK PINE PROJECT (MINERAL GULCH), IDAHO – COMPILATION UPDATE
Pilot Gold has recently recovered a large historical digital database from the recently acquired (see news release dated June 16, 2016), past-producing Black Pine heap leach gold mine located in southeastern Idaho. The database includes drill data for 1,866 holes (191,481m), as mined topography CAD files and 4,950 rock samples. The drill hole data includes collar and survey data, fire assay gold, acid soluble gold and silver, lithology and alteration.
The data is currently being compiled and verified pursuant to generating a 3D model to direct drill targeting. Compilation work will be released in a timely basis and targets will be generated in advance of in-fill and step-out drilling planned for the summer of 2017. The recovery of over 1,300 additional drill holes is expected to save millions of dollars and several years of permitting and drilling.
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 vary between 30 and 100% of the reported lengths due to varying drill hole orientations, but are typically in the range of 60 to 80% of true width. 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. Metallic screen techniques may be employed where the presence of coarse free gold is suspected. Approximately 1000 grams of coarse reject material are pulverized and screened. Two splits of the fine fraction are assayed, as well as all material that does not pass through the screen (the coarse fraction). The final gold assay reported is a weighted average of the coarse and fine fractions. 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 and Black Pine are early-stage exploration projects and do not contain any mineral resource estimates 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.
