NewCastle Gold Intersects Further High-Grade at Oro Belle South with 31.32 g/t Gold over 12.8 Metres

TORONTO, ON--(Marketwired - May 16, 2017) - NewCastle Gold Ltd. (TSX: NCA) (NewCastle Gold or the "Company") is pleased to report the first large tranche of assay results, including additional high-grade intercepts, from the recently completed definition drill program on the southern portion of the main Oro Belle Trend ("OBT") at the Castle Mountain gold project (the "Project") in San Bernardino County, California. These results form part of the Phase II definition and exploration drill program ("the Program") that ran from November 1, 2016 to March 31, 2017 and totaled 121 holes/44,500 metres of reverse circulation ("RC") and diamond core drilling using seven drill rigs.

Core drill hole CMM-175C, located 150 metres south from previously reported hole CMM-195 (31.19 grams per tonne gold ("g/t Au") over 29.0 metres; see press release dated April 1, 2017), was planned to further test the high-grade gold mineralization associated with the steeply dipping Lucky John Zone/OB-2 fault corridor ("OB-2") and large scale hydrothermal breccias. CMM-175C intersected 31.32 g/t Au over 12.8 metres at the same elevation as the intercept in CMM-195. Another hole, 150m north of CMM-175C, also intersected the OB2 structure with 17.01 g/t Au over 3.0 metres in hole CMM-204. The OB-2 target remains open along strike to the north and south, as well as at depth, with follow-up drilling currently underway in the area of hole CMM-175C.

In addition, core hole CMM-180C on the same section 11600N intersected a wide intercept of gold mineralization on the other side of the rhyolitic dome with 1.13 g/t Au over 196.5 metres. This intersection confirms a parallel subvertical north-south fault, to OB-2, namely OB-3, and demonstrates the importance of the structural fabric of the high-grade mineralization with an intercept of 14.74 g/t Au over 4.0 metres.

Gerald Panneton, President and CEO commented, "We are very encouraged by the ongoing success that our exploration team is having in defining both high-grade gold mineralization and also new zones beyond the limits of the resource. The Program is also providing ample new targets to extend gold mineralization at depth and along strike to the north where hole CMM-235 has extended the mineralization. Additional follow-up drilling is underway with two drill rigs on multiple targets to extend these zones."

Assay results have been received from the 32 holes drilled through the JSLA backfilled pit area ("JSLA North"; the backfill results were previously released by the Company on May 2, 2017). The holes released today are targeting the underlying portions of the 2015 mineral resource classified as Inferred or Waste, inside the US$1,100 modeled pit, on approximately 100-200 foot centers. Some of the holes also extended into the footwall sequence along structural corridors to test for zones of high-grade. The results from these holes extend the limits of gold mineralization well below the modeled pit limits for distances up to 150 metres (~500 feet). Deeper intercepts define a broad zone over 350 metres long (~1,150 feet) and open at depth to the north and south which may also correlate to the new FW Zone discovery previously reported in CMM-195.

Significant assay highlights from 14 of the 32 completed holes to date are shown in Table 1, and in the attached plan maps, cross-section 11600N, and oblique longitudinal section and include:

Section 11600N

  • 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

Section 11675N

  • 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

Section 11750N

  • 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

Section 11800N

  • 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

Section 12000N

  • 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.
