Heliostar Drills 46.0 m Grading 13.4 g/t gold within
129.2m Grading 6.0 g/t gold at Ana Paula, Mexico
Highlights:
• Hole AP-23-293
- 129.2 metres @ 6.0 grams per tonne (g/t) gold including;
- 46.0 metres @ 13.4 g/t gold including;
- 28.5 metres @ 17.4 g/t gold
• Hole AP-23-294 (drilled above the High Grade Panel)
- 13.95 metres @ 6.4 g/t gold;
• The results from AP-23-293 are the most significant reported in Heliostar’s reassessment of the
High Grade Panel. They infill a gap in the resource to connect a now continuous 195-metre-long
strike length of drill hits with more than 15 grams per tonne of gold.
Vancouver, Canada, June 12 th, 2023 – Heliostar Metals L td. (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG 1)
(“Heliostar” or the “Company”) is pleased to report additional drill results from the Ana Paula project in
Mexico. These four holes continue to assess mineralization within and above the High-Grade Panel at the
core of Ana Paula. This is the area of the deposit that Heliostar believes has the potential to increase grade
significantly. This drill program will evaluate Ana Paula’s ability to host a high-margin, underground gold
mine development opportunity.
Heliostar CEO, Charles Funk, commented, “The key to our vision for Ana Paula ’s future is to define high-
grade, underground-minable gold mineralization . The current drill program ’s exceptional intercepts
reinforce this view. The results from hole AP-23-293 illustrate the potential with a 139% increase in grade
relative to the current resource model, at a >5 g/t cut-off grade. This hole fills a gap in the historic model.
It connects a continuous 195-metre-long strike length of drill hits with more than half an ounce of gold per
tonne (15 g/t). The crew on site has moved to drill -test the up -plunge target next. This target has the
potential to extend the strike length of the High Grade Panel.
Ana Paula is an advanced gold project with over US$75M in recent exploration and development
expenditures. These drill results are a critical part of re-scoping the Ana Paula project’s economics as an
underground mine. The re-scoping program includes drilling, underground mine design, geometallurgical
optimization studies and a resource update all of which will be delivered in 2023.
The Company believes this program will deliver a technically simpler project with better economics and a
materially improved Net Present Value (NPV) for Ana Paula.

Drill hole AP-23-293 targeted one of the largest data gaps near the center of the High-Grade Panel. The
goal of AP-23-293 was to test the continuity of high-grade gold mineralization across this gap.
Assay results for AP-23-293 show 46 metres at 13.4 g/t gold , within 129.2 metres at 6.0 g/t gold . These
grades and widths represent a 139% increase over the resource modeled grades and widths at a 5 g/t gold
cut-off grade. This will positively affect the total ounces and grade of gold in the resource model. It adds
critical geologic data in the vicinity of this hole. Furthermore, the result is above expectations set by the
next closest drill holes. This demonstrates that Ana Paula has the potential to continue to grow through
improved drill spacing.
Continuity of gold mineralization remains a feature of the High Grade Panel with only three of forty-nine
samples that make up the 46 metres at 13.4 g/t gold in AP-23-293 returning less than 2 g/t gold.

Drill holes AP -23-294, 295, and 296 are lower priority holes completed whilst awaiting drill pads to be
prepared for the up-plunge target.
Hole AP-23-294 returned an unexpectedly better intercept of 13.95 metres at 6.4 g/t gold within 67.2
metres at 2.1 g/t gold. These results came from an area where the model only indicated grades below 5
g/t gold.
Hole AP-23-295 contained 5.5 metres at 4. 9 g /t gold within 41.5 metres at 2. 6 g /t gold. AP -23-296
returned 2 .0 metres grading 13.6 g/t gold. These results were respectively 63% and 46% lower than
predicted by the model at a greater than 5 g/t cut-off.
The three holes competed above the panel extended potentially mineable underground grades over a
vertical range of 170 metres. They show that mineralization extends more shallowly than modelled and
in more discrete narrow zones than within the High-Grade Panel. They are expected to add underground
mineable ounces in the 2023 resource update.
Drilling Progress
Currently eleven holes have been completed at Ana Paula in the current program. Heliostar has reported
results from six holes to date . The next drill h ole, AP-23-297, tests the up -plunge extension of
mineralization and then continues deeper into the target. Ultimately, it will assess the internal continuity
of the High-Grade Panel. It will also contribute a large amount of sample material for the metallurgical
program. Holes AP-23-298 to AP-23-301 all test zones in the up-plunge target.

Quality Assurance / Quality Control
Core samples were shipped to ALS Limited in Santiago Queretaro, Queretaro for sample preparation and
for analysis at the ALS Laboratories in North Vancouver. The North Vancouver ALS facility is ISO/IEC 17025
certified. Gold was assayed by 30 -gram fire assay with atomic absorption spectroscopy finish and
overlimits were analysed by 50g fire assay with gravimetric finish.
Control samples comprising certified reference samples and blank samples were systematically inserted
into the sample stream and analyzed as part of the Company’s quality assurance / quality control protocol.
