Drilling Returns 16.47 g/t Gold Over 15.2 Metres Within a Larger Zone of 2.77 g/t over 103.6 Metres at Oro Belle South

TORONTO, ON--(Marketwired - June 06, 2017) - NewCastle Gold Ltd. (TSX: NCA) (NewCastle Gold or the "Company") is pleased to report the latest assay results on the southern portion of the main Oro Belle Trend ("OBT") within the region of the historic JSLA pit at the Castle Mountain gold project (the "Project") in San Bernardino County, California.

The results from CMM-161 are very encouraging, returning 2.77 grams per tonne gold ("g/t Au") over a large interval of 103.6 metres including 16.47 g/t Au over 15.2 metres, below the modeled pit bottom and approximately 100 metres up-dip from CMM-031Ext (1.63 g/t Au over 27.1 metres, including 9.50 g/t Au over 3.0 metres in the September 6, 2016 press release). The OB-2 and OB-3 Zones, and the intervening corridor which hosts the bulk of felsic intrusive activity and brecciation, remains open along strike to the north and south, as well as at depth.

Gerald Panneton, President and CEO commented, "The Company's definition drilling program continues to generate high-grade mineralization intercepts outside the previously announced 2015 mineral resource. The current program has definitely achieved its objective to demonstrate that the deposit is still open in all directions and that the average grade of the resource could be significantly increased."

New assay results have been received from a total of 30 core and reverse circulation ("RC") drill holes located south of the historic JSLA backfilled pit area ("JSLA South"). These holes were targeting portions of the 2015 mineral resource classified as inferred or waste inside the US$1,100 modeled Whittle pit, on approximately 100 to 200 foot centers. Selected drill holes also tested the modeled structural corridors ("OB-1/2/3 Zones") for areas of higher grade gold and were drilled well into the footwall sequence. These results form part of the Phase II definition and exploration drill program ("the Program") that took place from November 1, 2016 to March 31, 2017, totaling 121 holes/44,500 metres of RC and diamond core drilling, using seven drill rigs. Complete or partial assay results have now been reported for 85 holes with an additional 36 holes remaining in Phase II. Significant assay highlights from the 30 completed holes can be found below, and in Table 1, Figure 1 and 2, and cross-section 11550N. Results include:

Section 11575N

• 0.81 g/t Au over 67.1 metres, in CMM-170
  • Including 2.71 g/t Au over 9.1 metres, and
• 0.42 g/t Au over 123.4 metres, in CMM-170
  • 1.64 g/t Au over 9.1 metres

Section 11550N

• 1.43 g/t Au over 50.3 metres, in CMM-165
  • Including 4.55 g/t Au over 12.2 metres
  • Including 12.54 g/t Au over 3.0 metres
• 0.78 g/t Au over 53.3 metres, in CMM-166
  • including 1.91 g/t Au over 9.1 metres, and
• 1.52 g/t Au over 18.3 meters, in CMM-166

Section 11500N

• 2.77 g/t Au (uncut)/ 1.60 g/t Au (cut) over 103.6 metres, in CMM-161
  • including 16.47 g/t Au (uncut)/ 8.53 g/t Au (cut) over 15.2 metres
  • including 73.95 g/t Au (uncut)/34.29 g/t Au (cut) over 3.0 metres

Section 11450N

• 0.81 g/t Au over 76.2 metres, in CMM-152
  • including 1.89 g/t Au over 15.2 metres

Section 11425N

• 1.28 g/t Au over 36.6 metres, in CMM-148
  • including 2.09 g/t Au over 12.2 metres, and
• 1.10 g/t Au over 22.9 metres, in CMM-148
  • 3.94 g/t Au over 4.6 metres

Section 11325N

• 0.48 g/t Au over 50.3 metres, in CMM-137
  • Including 1.64 g/t Au over 6.1 metres

All new core and RC holes were drilled at 290 degrees azimuth, with dips of -50 or -60 degrees and to a range of depths from 213 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 and reverse circulation 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 um) 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).

Half-sawn core and 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 um) 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 augustagroup 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 1991 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 steep and shallow-dipping orientations.
