NewCastle Gold Drilling Expands Mineralization With 1.01 g/t Gold Over 179.8 m, Including 5.49 g/t Gold over 19.8 m

TORONTO, August 29, 2017 - NewCastle Gold Ltd. (TSX: NCA) ("NewCastle Gold" or the "Company") is pleased to report further assay results from the southern part of the historic JSLA back-filled pit ("JSLA South"), at the Castle Mountain gold project (the "Project") in San Bernardino County, California.

New assay results from an additional 10 core and reverse circulation ("RC") drill holes were received, targeting portions of the 2015 mineral resource classified as inferred or waste, and below the 2015 pit resources. The results are part of the Phase II definition and exploration drill program ("the Program") that took place from November 1, 2016 through to April 30, 2017, totaling 121 holes/44,500 metres of RC and diamond core drilling.

Results include a twin hole of CMM-161 (see press release dated June 6, 2017: Drilling Returns 16.47 g/t Gold Over 15.2 Metres Within a Larger Zone of 2.77 g/t Gold Over 103.6 metres in). Hole CMM-161A was completed as a twin to supplement hole CMM-161, where 52 samples in the upper portion of the hole were assigned a zero grade due to illegible sample bags. Twin hole CMM-161A reported a broader zone averaging 1.01 g/t grams per tonne gold ("g/t Au") over 179.8 metres, including a higher grade zone of 5.49 g/t Au over 19.8 metres. This gold mineralization relates to the steeply southeast dipping, northeast trending OB-3 Zone mineralized trend.

Gerald Panneton, President and CEO commented, "We continue to report excellent results from our latest drill program as we keep extending gold mineralization at depth, most recently in hole 161A, and also near-surface in hole 163A. The size and strength of the mineralized system continues to impress us and it is still open in all directions and at depth. As a consequence, we will be starting a 10,000 m follow up program in early September with one RC and one core drill rig."

Significant assay highlights from the 10 completed holes can be found below, and in Table 1, Figure 1 and 2, and generalized cross-section 11550N (Figure 3). Results include:

Section 11550N

• 0.89 g/t Au over 147.8 metres, in CMM-167
  • 2.45 g/t Au over 30.5 metres
• 0.87 g/t Au over 42.7 metres, in CMM-163A
  • Including 3.37 g/t Au over 7.6 metres

Section 11525N

• 1.01 g/t Au over 179.8 metres, in CMM-161A
  • Including 1.62 g/t Au over 76.2 metres
  • Including 5.49 g/t Au over 19.8 metres
  • Including 24.05 g/t Au over 3.0 metres

Section 11475N

• 0.95 g/t Au over 29.6 metres, in CMM-156C
  • including 1.84 g/t Au over 11.1 metres

Section 11300N

• 0.38 g/t Au over 83.8 metres, in CMM-137A
  • including 1.84 g/t Au over 6.1 metres

All new core and RC holes were drilled at 290 degrees azimuth, with dips of -60 degrees and to a range of depths from 152 to 457 metres. True widths of the intercepted intervals are estimated to be 70% to 90% of intersected widths based on available geological information.

The Company remains on target to revise its current mineral resource statement by the end of September 2017.

Assays and Quality Assurance/Quality Control

Half-sawn core drill samples were submitted to ALS Minerals in Reno, Nevada for crushing until 70% of the sample is finer than a nominal two millimeters in size. A 250 gram ("g") sub-sample is taken from the crushed material and pulverized until 85% passes a 200 mesh (75 µm) screen (ALS Method PREP-31). A 30 g portion of pulverized material (pulp) is then sampled and subjected to fire assay ("FA") with atomic absorption ("AA") finish (ALS Method AuAA-23). Any gold assays greater than 10 g/t Au are re-analyzed where a 30 g portion is taken from the pulp and assayed by FA with a gravimetric finish (ALS Method Au 30 g FA €“ GRAV). All samples that yield greater than 0.2 ppm assay are also analyzed for gold cyanide solubility (ALS Method AuAA-13).

Reverse circulation drill samples drill samples were also submitted to Inspectorate America Corporation in Sparks, Nevada for crushing until 70% of the sample is finer than a nominal two millimeters in size. A 250 g sub-sample is taken from the crushed material and pulverized until 85% passes a 200 mesh (75 µm) screen (Method PRP70-250). A 30 g portion of pulverized material (pulp) is then sampled and subjected to fire assay ("FA") with atomic absorption ("AAS") finish (Method FA430). Any gold assays greater than 10 g/t Au are re-analyzed where a 30 g portion is taken from the pulp and assayed by FA with a gravimetric finish. All samples that yield greater than 0.2 ppm assay are also analyzed for gold cyanide solubility (Method CN403).

The Company employs an industry-standard QA/QC program consisting of standard pulps, coarse blanks and rig duplicates.

About NewCastle Gold

NewCastle Gold (an Augusta group company) has a 100% interest in the Castle Mountain property in San Bernardino County, California. The Castle Mountain heap leach gold mine produced over one million ounces of gold from 1992 to 2004. The Mine and Reclamation Plan, under which the mine operated, was authorized by the County of San Bernardino as the Lead Agency and remains in effect. Water for the drill programs was accessed from existing patented wells on the Project.

An updated NI 43-101 resource for the project was announced December 2, 2015 which includes Measured Mineral Resources of 17.4 million tonnes grading 0.86 g/t gold containing 0.48 million gold ounces, Indicated Mineral Resources of 202.5 million tonnes grading 0.57 g/t gold containing 3.71 million gold ounces along with Inferred Mineral Resources of 40.8 million tonnes grading 0.58 g/t gold and containing 0.76 million gold ounces. The Project hosts a disseminated low sulphidation epithermal system. Gold is primarily hosted by late-stage rhyolite volcanic units within zones of silicification and brecciation associated with northeast-southwest trending/southeast dipping fault structures which are interpreted to have developed within a collapsed caldera environment. Eleven gold domains are represented by both steeply dipping high grade and stratabound hosted mineralization orientations.
