MILLROCK PARTNER POLARX REPORTS DRILL RESULTS

FROM ZACKLY COPPER-GOLD DEPOSIT, ALASKA RANGE

PROJECT, ALASKA

VANCOUVER, BRITISH COLUMBIA, November 23, 2017 - Millrock Resources Inc. (TSX-V:

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.
