VANCOUVER, British Columbia, Aug. 16, 2018 (GLOBE NEWSWIRE) -- Millrock Resources Inc. (TSX-V: MRO, OTCQX: MLRKF) ("Millrock") announces that PolarX Mining Inc. (“PolarX”) (ASX: PXX) has reported the first assay results for 2018 from drilling at the Zackly copper-gold deposit within its Alaska Range Project.

Results from hole ZX-18020 are presented below:

ZX-18020From (m)To (m)Interval (m)Cu %Au g/tAg g/t
 2.557.154.6 0.6*2.8  9.5
Including:2.514.011.50.65.312.0
and:18.327.18.80.55.8  4.5
and:32.043.311.30.81.823.3
and:46.257.110.9  1.0*1.6  3.9

* These intersections include an uncut assay grading 27.3% Cu over a narrow interval of 0.3 meters between 56.7 meters and 57.0 meters The drill intersection reported is apparent thickness. Due to the structural complexity in this area, in which several conjugate faults have been inferred, the true thicknesses of the mineralization cannot be ascertained until further drilling has been undertaken.

The drill intersection includes a 0.3 meter down-hole thickness from 56.7 meters which assayed 27.3% copper, 2.5 grams per tonne (“g/t”) gold and 82.5 g/t silver. The gold and copper mineralization in ZX-18020 occurs in garnet bearing skarn alteration located above a fault. Visible copper mineralization occurs in veins, fractures, and interstitial to grains, as native copper flecks and silicified chalcocite with variation in intensity throughout each mineralized zone. Gold is also present throughout this zone, although no visible gold was observed in this hole. Further information, maps and cross sections are available of the PolarX website.

Exploration at the Alaska Range Project is being done by Millrock on behalf of PolarX. Millrock presently owns 6.44% of the issued and outstanding PolarX shares and is entitled to certain milestone and royalty payments on portions of the project.

Quality Control – Quality Assurance
Millrock adheres to stringent Quality Assurance – Quality Control (QA/QC) standards. Drill core samples are kept in a secure location at all times. Representative half core samples were collected and assayed at ALS Chemex laboratories in Vancouver, Canada and Reno, Nevada, USA, after being prepared at the preparatory laboratory in Fairbanks, Alaska, USA. Gold was analyzed by Fire Assay (specifically ALS code Au-AA25 - Au by fire assay and AAS using a 30 gram nominal sample weight). Other elements (33 in total including copper) were analyzed using ALS method code ME-ICP61 which involves a four-acid digest and an ICP-MS finish. Over range (Cu >= 1%) was analyzed using ALS method code ME-OG62 which involves a four-acid digest and an ICP-AES or AAS finish. The following QA/QC protocols have been adopted for this program: 1) Blank samples and Standards – Certified Reference Material (CRM’s) account for approximately 10% of core samples submitted to the laboratory, 2) QA/QC samples are spaced no more than ten samples apart, 3) geologists instruct the lab to run clean rock through equipment immediately following samples containing visible native gold and / or copper, and 4) the laboratory prepares coarse crush and fine pulverized duplicate samples and analyzes the duplicates. All results from blanks, standards and duplicates were reviewed and found to be accurate within acceptable tolerances for results obtained to date. The Qualified Person is of the opinion that the results reported in this press release are reliable.
