MILLROCK AND RESOLUTION ANNOUNCE INITIAL
DRILL RESULTS FROM HOLE 20AU001 AND
PLANNED DRILLING RESUMPTION, AURORA
TARGET, WEST POGO BLOCK, 64NORTH GOLD
PROJECT, ALASKA
Highlights:
• Assay results from the upper two thirds of Hole 20AU001 intersected multiple zones of
gold mineralization associated with elevated arsenic and bismuth concentrations in a
robust hydrothermal system.
• The upper portion of hole 20AU002 contained zones of quartz - sulfide mineralized rock.
This hole was suspended in progress at 194 meters depth (planned depth 600 meters)
due to travel restriction concerns of the drill contractor relating to COVID-19 virus.
• The remainder of hole 20AU001 and 20AU002 have been logged, sampled and sent to
the laboratory; assays are pending.
• A drilling program continuation is planned for late May 2020.
• The drilling plan includes completion of hole 20AU002, and four or five additional drill
holes totaling approximately 2,400 meters with strict COVID-19 related safety protocols
in place.
• An overall US$5 million exploration program is planned for 2020. Regional targets are to
be advanced to create a pipeline of drill-ready targets.
VANCOUVER, BRITISH COLUMBIA, April 27, 2020 - Millrock Resources Inc. (TSX-V: MRO,
OTCQB: MLRKF) ("Millrock" or the “Company”) is pleased to provide an update on drilling at its
64North Gold project. Exploration work is being funded and managed by Resolution Minerals
(“Resolution” ASX: RML) in a collaborative arrangement with Millrock as the project operator.
The 64North Gold Project is a very large tract of claims in Alaska’s emerging Goodpaster Gold
District.
The target being drilled at the Aurora prospect is adjacent and immediately west of the Pogo
Mine property, which is owned and operated by Northern Star Resources Ltd. (ASX: NST)
(“Northern Star”). Northern Star has previously reported a gold resource of 5.95 million ounces
of gold in a series of veins grading 9.6 grams per tonne gold (Source: Northern Star website).
More than four million ounces of gold has already been mined at Pogo, and Northern Star has
announced a new gold discovery called the Goodpaster deposit a short distance away from the
mutual claim boundary. Millrock cautions that mineralization on the nearby Northern Star
property is not necessarily indicative of gold mineralization hosted on the Company’s property.

Millrock President & CEO commented: “The core we drilled in the first hole of the program
demonstrated a Pogo-like system with an abundance of alteration and sulfide mineralization
indicating a robust hydrothermal system. Gold values are not strong, but the mineralization we
have intersected appears to be similar in character to Northern Star’s Goodpaster gold deposit.
located immediately to the northwest of our Aurora prospect. The resumption of drilling will
continue the systematic exploration of the favorable geophysical and structural/stratigraphic
targets that comprise the Aurora prospect area.”

Hole 20AU001 was collared at an azimuth of 145 degrees and a dip angle of -80 degrees. It
was drilled to a depth of 462.4 meters. An interval from 119 to 137 meters of hole 20AU001
intersected multiple thin quartz sulfide veins containing elevated gold, arsenic, bismuth and
tellurium enveloped by strong dolomite sericite alteration. This zone is similar to the
mineralization reported from the Goodpaster deposit by Northern Star.
At 137 meters alteration transitioned to sericite dominant and then weakened at 181 meters.
Dolomite-sericite alteration increased at 200 meters and continued to 246 meters with a quartz
breccia arsenopyrite zone at 242 meters. From 260 meters to 312 meters the alteration is silica
dominant, and at 276 meters to 278 meters there is zone with abundant fine grained
arsenopyrite. Each of the zones is elevated strongly in arsenic, moderately in bismuth with weak
but anomalous gold values. The lower part of the hole, which is yet to be assayed, also contain
quartz veins with arsenopyrite.
The following table documents intervals exceeding 0.3 grams per tonne gold. It is not known
with certainty whether these intersections represent true width. Further information from other
drill holes is needed.

Aurora Target & Planned Drilling Restart

The Aurora target is a two by five-kilometer-long zone of low-magnetic rocks adjacent to a late
diorite intrusion. The setting is very similar to that observed at the Pogo Mine. Millrock
postulates that the late diorite body intruded along a westerly extension of the Liese Creek fault,
which is known to have played a key role in the genesis of the Pogo gold deposits. Highly
anomalous gold-bismuth-arsenic in soil is documented. High-angle gold-bearing quartz veins
have been intersected by prior drilling, however, the few holes drilled by earlier workers did not
go deep enough to intersect the low-angle, regional shear zone that is known to host gold at
Pogo and the Goodpaster Deposit. Millrock believes this structure exists at the Aurora target.
Numerous zones of mafic rocks intercepted in drill hole 20AU001 fit with the exploration model.
The low-angle, regional shear preferentially ruptured the mafic lithological layers. The Aurora
target is located in this regional shear.
From a recent CSAMT survey, the depth to the shear zone is 150 meters on the east and 450
meters depth on the west end of the Aurora target. Hole 20AU001 has confirmed that the
CSAMT conductive zone represents a series of shallow-dipping fault zones with quartz, quartz
breccia, and sulfide minerals.

Quality Control and 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. For this program representative half-core
samples underwent sample preparation at ALS Chemex prep laboratory in Fairbanks, Alaska
USA. Samples were subsequently analyzed at ALS Chemex laboratories in Vancouver,
Canada. 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 (48 in total) were analyzed
using ALS method code ME-MS61 which involves a four-acid "near total" digestion and an ICP-
MS + ICP-AES finish. The following QA/QC protocols have been adopted for this program: 1)
Duplicates were created as coarse crush duplicates on every 50th sample (2% insertion) in the
sample preparation process at the laboratory, and 2) Blank material was inserted at a rate of 2
blanks per 100 samples (2% insertion) and 3) Standards – Certified Reference Material (CRM’s)
every 20th sample (5% insertion) plus additional random insertions at supervising geologist’s
discretion. All results from duplicates, blanks, and standards were reviewed and found to be
accurate within acceptable tolerances for results obtained to date.
