Heliostar Adds Porphyry Upside with 71.6 Metres of 0.44
g/t AuEq at Zachary Bay, Unga Project, Alaska
Vancouver, Canada, September 16th, 2021 – Heliostar Metals Limited (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG)
("Heliostar" or the "Company") is pleased to announce results from two Reverse Circulation (RC) holes
completed at the Zachary Bay Target in 2021.
Our primary focus at Unga is high grade gold targets. However, the project also hosts both porphyry gold-copper
and bulk tonnage gold targets. These two first-pass RC holes targeted porphyry style mineralization at Zachary
Bay and both holes intersected gold and copper mineralization over significant widths . They indicate
potential for a large porphyry footprint with zones of higher grade that require additional drilling.
Highlights
• Two holes completed 220 metres apart show open intersections , with local higher -grade zones
within each hole.
• Next step is diamond drilling to expand upon higher grade zones , in particular to depth, and drilling
the magnetic highs within the porphyry complex.
ZBRC21-01
• 0.44 g/t gold equivalent (AuEq) over 71.63 m from 30.48 metres (m) downhole, including;
• 0.58 g/t AuEq over 16.76 m from 30.48 m, including;
• 0.69 g/t AuEq over 6.10 m from 30.48 m
ZBRC21-02
• 0.34 g/t AuEq over 91.44 m from 9.14 m including;
• 0.40 g/t AuEq over 41.15m from 9.14 m
Note: All numbers are rounded and widths represent drilled lengths.
Heliostar CEO, Charles Funk, commented “Unga is a rare project containing the potential for multiple deposit
types. These holes show the potential for a gold-copper porphyry at the Zachary Bay target . They represent first
pass drilling to establish the best location for follow-up diamond drilling. Both holes have higher grade sub-zones.
It is important to note that hole ZBRC21-02 has grades that increase with depth and the best intervals are at the
very base of the hole. High grade gold is the company’s primary focus , however the proximity of the different
deposit styles, as was the case at the Saddle and Saddle North deposits that GT Gold (now Newmont) discovered
in northern British Columbia highlights the potential value creation of exploring both styles of mineralization.”

Zachary Bay Target
The Zachary Bay Porphyry is a compelling drill target based on several factors:
• The overall size of the porphyry core (300 x 650 m) based on mapping and ground magnetics surveys;
• A zoned alteration from (500 x 1,000 m) from outer propylitic, argillic and advanced argillic alteration in
andesite to a core of potassically alterted porphyritic diorite;
• Only a single 117 metre deep, vertical hole drilled within the porphyry prior to Heliostar . This hole was
mineralized over its entire length;
• The proximity to the potentially related, high grade vein corridors.
A joint Quintana Minerals Corp. and Duval Corp. exploration program identified Zachary Bay in 1974. One round
of drilling was completed with 4 holes totalling 291 metres in 1975. Of these four holes, only one was drilled in

the porphyry and the other holes were drilled at other targets located over 400 metres to the east of Zachary
Bay.
The 1975 hole (Z1) was drilled vertically, a poor orientation to effectively test a large, sub -vertical porphyry
complex, but nonetheless returned 0.45 g/t gold equivalent over 107.1 metres (0.28 g/t gold and 0.11 % copper),
with individual gold values up to 0.95 g/t. Mineralization remains open in all directions (The reader is cautioned
that the qualified person has not been able to independently verify the historical assay results in the Quintana
Duval drilling).

Bay hole ZBRC21-01 cross section looking to the north.
Heliostar’s compilation of the historic drilling, magnetic surveying, and two IP survey lines from 2005, combined
with detailed field mapping completed by Heliostar in early 2021 confirmed a large porphyry system at Zachary
Bay, with large areas masked by thin (0-10 metres) overburden.
The team completed two RC holes to test the extent of the porphyry complex. Hole ZBRC21-01 was a 135 metre
step towards the south from 1975 hole Z1. The entire hole returned 118.9 m of 0.39 g/t gold equivalent (0.1 5
g/t gold and 0.1 5% copper) from 9.14 m in a diorite porphyry covered by thin overburden. Within this zone
intervals of higher grade include 16.76 m at 0.58 g/t gold equivalent , with individual assays up to 0.4 2 g/t gold
and 0.3 % copper.

The presence of both higher grade zones of mineralization and variable gold-to -copper ratios suggest multiple
porphyry and alteration phases. Testing the extension of these zones will be the focus of follow-up drilling.
Hole ZBRC21-02 is located at the edge of the northern magnetic high, 108 metres northeast of the historic hole
Z1. The location is near a small outcrop containing magnetite and chalcopyrite veining hosted by diorite porphyry.
The entire hole contained gold and copper mineralization from surface to the end of hole at a depth of 100.58
m. Grades for the interval average 0.34 g/t gold equivalent (0.19 g/t gold and 0.09 % copper).
However, most significant is that the mineralization increased towards the end the of the hole which terminated
in 3.05 m of 0.64 g/t gold equivalent ( 0.41 g/t gold and 0.14% copper). The ho le is drilling towards the most
intense magnetic high within the Zachary Bay target but ended due to limitations of the RC drill rig before testing
the magnetic target. This will be a clear target for follow-up drilling.

Quality Assurance / Quality Control
Drill samples were shipped to ALS Limited in Whitehorse, Yukon for sample preparation and for analysis at the
ALS laboratory in North Vancouver. The ALS Whitehorse and North Vancouver facilities are ISO/IEC 17025
certified. Silver and base metals were analyzed using a four-acid digestion with an ICP finish and gold was assayed
by 30-and 50 gram fire assay with atomic absorption (“AA”) spectroscopy finish and overlimits were analyzed by
50g fire assay with gravimetric finish.
Control samples comprising cer tified reference samples, duplicates and blank samples were systematically
inserted into the sample stream and analyzed as part of the Company’s quality assurance / quality control
protocol.
