TORONTO, ON--(Marketwired - February 22, 2017) - NewCastle Gold Ltd. (NCA.TO) (NewCastle Gold or the "Company") is pleased to report additional assay results from ongoing angled drilling on the South Domes target ("South Domes") at the Castle Mountain gold project (the "Project") located in San Bernardino County, California. This work is part of the 40,000 metre Phase II definition and exploration drill program ("the program") that commenced November 1, 2016.
Results are from 30-metre spaced cross-sections 10600N, 10570N and 10540N at South Domes to follow up on previously reported results. Assays from six (6) new drill holes support the advancement of this exciting target with the longest intercept reported to date by the Company in hole CMM-129. New drilling continues to push the extent of gold mineralization beyond currently modeled mineral resources and pit limits, with hole CMM-129 ending in mineralization 100 metres below the modeled pit shell. The South Domes target remains open along strike to the north and south and at depth.
Assay highlights from two (2) core and four (4) reverse circulation ("RC") drill holes include:
- 1.07 grams per tonne gold ("g/t Au") over 192.9 metres in hole CMM-122C
- including 1.98 g/t Au over 77.3 metres
- including 20.10 g/t Au over 4.6 metres
- 1.63 g/t Au over 275.8 metres in hole CMM-129
- Including 2.05 g/t Au over 204.2 metres
- Including 5.43 g/t Au over 48.8 metres
- 0.55 g/t Au over 135.6 metres in hole CMM-133
- Including 4.04 g/t Au over 9.1 metres
- 2.10 g/t Au over 38.1 metres in hole CMM-133
- Including 5.03 g/t Au over 9.1 metres
- 0.74 g/t Au over 113.7 metres in hole CMM-134C
- Including 2.59 g/t Au over 19.7 metres
- Including 10.08 g/t Au over 3.0 metres
Gerald Panneton, President and CEO commented: "The South Domes area continues to demonstrate the open potential of this exciting target with gold mineralization well above average resource grade. Gold mineralization is being intersected both outside modeled pit limits and at depth. South Domes continues to be our prime exploration target as the deposit is open in all directions. We have added a core drill to the South Domes area to continue expanding the deposit."
There are seven (7) rigs actively drilling at the Castle Mountain project. The current drill program is approximately 50% complete with 20,000 metres of core and RC drilling as of February 20, 2017. Eighty percent (80%) of the program is focused on bringing the South Oro Belle pit to the mineral reserve category after completion of the ongoing pre-feasibility study work. The remainder is focused on the growth of the South Domes area, and further exploration on the property.
Gold mineralization at South Domes is characterized by broad, shallow east-dipping zones within felsic flows, pyroclastic and intrusive units, with narrower steeply-dipping higher grade zones associated with hydrothermal breccias and quartz-feldspar porphyry intrusive bodies.

All new exploration holes were drilled at 290 degrees azimuth, with dips of -60 degrees and to an average depth of 250 to 600 metres.
Reverse circulation drill samples from hole CMM-133 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 from holes CMM-122C/126/129/131/134C were 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 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 steep and shallow-dipping orientations.
