NewCastle Gold Intersects Further High-Grade at Oro Belle South with 31.32 g/t Gold over 12.8 Metres
31.32 g/t Au (uncut)/ 14.20 g/t Au (cut) over 12.8 metres, in CMM-175C (Lucky John Zone)
-- including 99.68 g/t Au (uncut)/ 34.29 g/t Au (cut) over 3.4 metres
1.13 g/t Au over 196.9 metres, in CMM-180C (OB-3 Zone)
-- including 2.11 g/t Au over 44.0 metres
0.36 g/t Au over 196.6 metres, in CMM-190 (OB-3 Zone)
-- Including 1.15 g/t Au over 9.1 metres, and
1.39 g/t Au over 33.5 metres
-- including 9.79 g/t Au over 3.0 metres
1.74 g/t Au over 47.2 metres, in CMM-204 (OB-2 Zone)
-- including 17.01 g/t Au over 3.0 metres
0.78 g/t Au over 57.0 metres, in CMM-209C (OB-2 Zone)
-- including 2.03 g/t Au over 13.1 metres
1.01 g/t Au over 77.7 metres, in CMM-235 (OB-3 Zone)
-- including 2.28 g/t Au over 21.3 metres
All new RC and core holes were drilled at 290 degrees azimuth, with dips of -60 degrees and to a depth of 200 to 530 metres. True widths of the intercepted intervals are estimated to be 70% to 90% of intersected widths based on available geological information.
The Phase II definition and exploration drill program is now complete and a follow-up exploration drill program has started with the focus on the higher grade mineralization along the OB-2 sub-vertical structure, the FW Zone outside the current pit limit, and the South Domes area. Geological and structural mapping has been completed over the South Domes and Oro Belle South pit areas to further refine the key controls on gold mineralization. The interpretation of new geological cross-sections is ongoing.
The Company remains on target to revise its current mineral resource statement for the Project 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 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).
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 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 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.
