Millrock Partner Reports Drill Intersections

VANCOUVER, BRITISH COLUMBIA, October 1st, 2018 - Millrock Resources Inc. (TSX-V:

MRO, OTCQX: MLRKF) ("Millrock") announces that PolarX Mining Inc. (“PolarX”) (ASX: PXX)

has reported additional assay results for 2018 from drilling at the Zackly copper-gold deposit

within its Alaska Range Project.

The following two drill intersections are from hole ZX-18020 and ZX-18024:

Hole ID From (m) To (m) Interval (m) Cu% Au g/t Ag g/t

ZX-18020 2.5 57.1 54.6 0.6* 2.8 9.5

Including: 2.5 14.0 11.5 0.6 5.3 12.0

and: 18.3 27.1 8.8 0.5 5.8 4.5

and: 32.0 43.3 11.3 0.8 1.8 23.3

and: 46.2 57.1 10.9 1.0* 1.6 3.9

ZX-18024 37.0 83.7 46.7 0.6 3.1 3.3

Including: 59.0 80.7 21.7 0.8 5.2 4.1

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.

Both holes were drilled on the same section 850 meters east of the Zackly copper-gold-silver

skarn deposit. ZX-18024 was drilled to undercut hole ZX-18020 by approximately 40 meters.

The mineralization begins just below surface and appears to be gently dipping at around 20

degrees. If the interpretation is correct the drilled intersections are close to true width. The

mineralization is hosted in skarn displaying relict bedding and occurs in quartz-sericite veining

and is open along strike and down dip. Further details with a map and cross section can be

found in the September 25, 2018 announcement made by PolarX, which is available on their

website.

The next two drill intersections are from hole ZX-18023 and ZX-18025:

Hole ID From (m) To (m) Interval (m) Cu% Au g/t Ag g/t

ZX-18023 20.8 30.1 9.3 3.3 2.3 19.7

ZX-18025 84.8 99.8 15.0 2.3 2.2 11.9

Both holes were drilled on the same section, 350 meters east of the Zackly copper-gold-silver

skarn deposit. ZX-18025 was drilled too intersect approximately 40 meters beneath the

mineralization intersected in hole ZX-18023, which confirmed the intersection of historic hole

Z86. The intersections indicate steeply dipping, high-grade copper-gold mineralization like that

observed in the Zackly deposit. The mineralization is of the magnetite skarn variety with copper

sulfides occurring as disseminated and vein-hosted chalcopyrite and bornite. Given the near-

vertical orientation of the mineralized zone, the true width is interpreted to be about 65% to 70%

of the drill interval indicated in the table above. Further details with a map and cross section can

be found in the September 20, 2018 announcement made by PolarX, which is available on their

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.
