Millrock Partner PolarX Reports Drill Results From Zackly Copper-Gold Deposit, Alaska Range Project, Alaska

VANCOUVER, BC--(Marketwired - November 23, 2017) - Millrock Resources Inc. (TSX VENTURE: MRO) (OTCQX: MLRKF) ("Millrock") is pleased to announce that PolarX (ASX: PXX) ("PolarX") has issued a press release concerning the recently completed drilling program at the Alaska Range Project in Alaska. Results from the first five holes of the program are reported. The Alaska Range Project is a new name given to the combined Stellar and Caribou Dome projects.

The work was executed by Millrock on behalf of PolarX. Millrock presently owns 10.74% of the issued and outstanding shares of PolarX and is entitled to certain milestone and royalty payments on portions of the project.

Assay results from the first five holes drilled into the deposit confirm the presence of high-grade copper and gold from near surface.

PolarX reported the following highlights drill intervals:

• 14.5m @ 2.5% Cu and 2.0 g/t Au from 34.9m in hole ZM-17007
• 5.3m @ 2.0% Cu and 2.7 g/t Au from 9.7m in hole ZM-17006
• 3.5m @ 3.9% Cu and 2.2 g/t Au from 99.1m in hole ZM-17002
• 2.8m @ 2.6% Cu and 0.5 g/t Au from 227.4m in hole ZM-17005

Note: The mineralized intervals reported are down-hole, measured thickness. There is insufficient interpretation of the mineralization to confidently report "true widths". However, it is noted that the mineralized lenses appear to be relatively steeply dipping. As such, "true widths", depending on hole dip angle, will be 50% to 60% of the reported down-hole, measured thickness.

PolarX also reported that the results indicate:

• mineralization is over wider intervals than previously expected (in comparison to historic drilling in two of the first holes); and
• the deposit extends further along strike than previously thought; and
• it remains open along strike and at depth.

Quality Control -- Quality Assurance
Millrock adheres to stringent Quality Assurance -- Quality Control (QA/QC) standards. Drill core and samples are kept in a secure location at all times. Representative quarter-core samples were collected and assayed at ALS Chemex laboratories in Vancouver, Canada and Reno, Nevada, USA. Gold was analyzed by Fire Assay (specifically ALS code Au-AA25 - Au by fire assay and AAS using a 30g 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) Duplicates were created as coarse crush duplicates on every 20th sample in the sample preparation process at the laboratory, and 2) Blanks every 20th sample, and 3) Standards – Certified Reference Material (CRM's) every 20th sample plus additional random insertions at supervising geologist's discretion. All results from blanks, standards and duplicates were reviewed and found to be accurate within acceptable tolerances for results obtained to date.

The scientific and technical information disclosed within this document has been prepared, reviewed and approved by Gregory A. Beischer, President, CEO and a director of Millrock Resources. Mr. Beischer is a Qualified Person as defined in NI 43-101.
