the High Grade Panel
• San Luis Target, a large jasperiod/vein zone with open gold drill intercepts and untested high gold
grades (3.0 m grading 11.35 g/t gold) on surface
• Drilling to test new targets commencing in September, 2023

or 2025
Vancouver, Canada, September 7th, 2023 – Heliostar Metals Ltd. (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG1)
(“Heliostar” or the “Company”) is pleased to introduce new growth targets at the Ana Paula project in
Mexico (“Ana Paula ” or the “ Ana Paula Project ”). The recent drill program has improved the
understanding on the controls on mineralization at Ana Paula. The Company has generated these targets
through a combination of new data and review of historic information.
Heliostar CEO, Charles Funk, commented, “To date in 2023, the team has been focussed on delivering the
re-scope goals set out by the Company for the High Grade Panel at Ana Paula. We have made significant
progress so far. Now the Company can build on th is foundation to demonstrate the resource growth
potential of the Ana Paula project. That starts with the significant recognition of a Parallel Panel just fifty
meters north of the High Grade Panel. It opens a well mineralized new target for expansion drilling. In
addition, the West Breccia, Expansion Zone, and San Luis targets are the highest priorities from a pipeline
of growth targets at Ana Paula. The team will prioritize the Parallel Panel and the West Breccia targets for
drilling this month.”
Growth Target Identification
The Company’s understanding of Ana Paula has built on the work of previous operators. This process led
to an evolution in the understanding of controls on gold mineralization. Most of the high-grade gold is
hosted in a diatreme breccia rock unit. This was the focus of exploration in the project ’s recent history.
The Company recognized that the breccia makes a great host rock and that it predates the mineralization
however structural controls play a far greater role in focusing gold mineralization.

Broad east-west faulting controls the earlier diatreme breccia emplacement and created excellent gold
pathways at Ana Paula. The results from the recent drill program at the High Grade Panel reinforce this
observation. Because the historic target was the breccia rather than the east-west fault structure, very
few holes in the current PFS resource are drilled in the best orientation to find these structures.

New Parallel Panel
As the recent drill program advanced, five Heliostar holes have probed the footwall of the High Grade
Panel. Completion of these drill hole on a more effective drill orientation began to define a new Parallel
Panel to the north of the existing High Grade Panel. The Parallel Panel target currently has dimensions of
200 metres long by 150 metres wide and remains open in all directions (Figure 2). The width is not well
defined as most historic holes intersected the Parallel Panel at a high angle. However, it appears to vary
from 2 to over 15 metres wide. Those holes returned long, high-grade intervals including.
- APM-17-15: 54.6 m grading 7.19 g/t gold
- APM-15-01: 97.6 m grading 4.64 g/t gold
- AP-11-72: 20.9 m grading 7.79 g/t gold
- AP-12-115: 9.5 m grading 5.06 g/t gold and
13.2m grading 5.39 g/t gold
Heliostar drilling in 2023 intersected the zone at a more representative orientation and has returned the
following intercepts.
- AP-23-299: 38.0m grading 6.95 g/t gold including 6.0m grading 23.3 g/t gold
- AP-23-304: 4.0m grading 10.7 g/t gold and 5.5m grading 4.13 g/t gold
- AP-23-296: 2.0m grading 13.6 g/t gold
- AP-23-303: 5.5m grading 4.15 g/t gold

The Company believes a systematic infill drill program of holes drilled in a north -south plane has a high
probability of adding gold ounces to a resource that could be mined using underground methods. The
Parallel Panel will be the first target tested in the growth drill program commencing in September.

Deep Expansion Zone
The Ana Paula resource is open at depth. The Expansion Zone sits beneath the High Grade Panel. The
previous owner recognized the potential of this zone and commenced a decline to better access the zone
for drilling. Drill results include.
- AP-11-70: 13.5m grading 29.1 g/t gold
- AP-13-215: 40.0m grading 6.3 g/t gold
- AP-12-86: 20.5m grading 6.0 g/t gold
- AP-12-90: 11.0m grading 4.0g/t gold
Access to the Expansion Zone is best from underground or utilizing directional drilling. The shallow targets
discussed previously will take priority ahead of the Expansion Zone for this reason alone.

West Breccia – A High Grade Panel Lookalike
The gold mineralization in the High Grade Panel at the core of Ana Paula has distinctive pathfinder
elements associated with it, including bismuth. Two deep drill holes, 300 metres west of the High Grade
Panel, intersected pathfinder anomalies as strong as those within the High Grade Panel (Figure 4; next
page). These holes also have narrow gold intercepts. However, there has not been any follow-up drilling
to chase potential gold mineralization similar to the High Grade Panel at the West Breccia.
Surface rock chips above the West Breccia target define multiple areas of gold anomalism with up to 2.77
g/t gold. Geophysics shows a similar chargeability anomaly as the area of the High Grade P anel. As a
shallow target, the West Breccia will be tested in in the next phase of exploration drilling.

San Luis
San Luis is a hybrid epithermal vein/skarn gold target with high gold grades sampled across a large area
of alteration. The target is located 5.5 kilometres east of Ana Paula. It begins at the property boundary
with Torex Gold and extends for over 2.5 kilometres of strike on the Company’s lands. The target is a zone
of intense silicification with gold and pathfinder elements that have epithermal quartz veins in the silicified
structures. Surface samples include.
- 3.0 m grading 11.35 g/t gold (Undrilled)
- 1.15 m grading 8.83 g/t gold (Undrilled)
- 0.5 m grading 16.7 g/t gold (Undrilled)

Two phases of drilling were completed historically, with best results of 3.05 metres at 3.32 g/t gold and
15.3 metres grading 1.18 g/t gold. These holes tested potential skarn contacts between the limestone
unit and the granodiorite intrusions. The silicified structures, which Heliostar geologists believe have the
highest potential, remain almost entirely untested.
San Luis is one of several regional targets that will be the focus of a new drill permit. Heliostar will target
them in 2024 once the permit has been received.
Amended Purchase Agreement
Heliostar and Argonaut Gold have amended the terms of the Ana Paula purchase agreement.
Argonaut Gold has agreed to defer the outside date of the US$2,000,000 cash payment associated with
the Feasibility Study to January 1 st, 2025. This is an extension of six months and represents the earliest
cash obligation Heliostar must meet.
In return, Heliostar agreed to re-imburse to Argonaut Gold US$150,000 in Ana Paula claim fees from the
closing of the transaction to June 30, 2023 . Additionally, Heliostar will cover certain transition services
and administration costs incurred during the handover of the asset.
Also, the open pit mine permit extension/new underground mine permit granting milestone was also
modified to clarify that the issuance of US$5,000,000 in shares will be divided by the VWAP of Heliostar’s
shares for the ten trading days ending on the last trading day immediately prior to the date of award of
the permits.
