• 88.05 m grading 8.82 g/t gold from 88.2 m including
o 35.5 m grading 13.03 g/t gold from 88.2 m
• 6.4 m grading 5.16 g/t gold from 39.8 m
• 14.3 m grading 4.19 g/t gold from 397.7 m

Vancouver, Canada – October 6, 2025 – Heliostar Metals Ltd. (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG1)
(“Heliostar” or the “Company”) is pleased to announce additional results from the current 15,000 metre drill
program at its 100% owned Ana Paula project in Guerrero, Mexico . The program has the primary goal of
converting inferred ounces to higher confidence classifications, as well as supporting the ongoing Feasibility
Study and testing the next exploration targets around the Ana Paula deposit.
Heliostar CEO, Charles Funk, commented, “The drill results from the ongoing Ana Paula program continue
to provide exciting results. The infill- focused drilling consistently returns broad, continuous intervals of
strong grades as expected and - in some instances - hitting higher grade material than is currently estimated
in the block model . We intend to make a construction decision for Ana Paula on the back of a Feasibility
Study that will allow us to have the mine in production at 100,000 ounces per year in 2028. Our
comprehensive plan to de -risk the deposit is ongoing and includes collecting additional technical data
beyond assays that will help us design the mine. We are pushing hard toward this goal and, as such, have
mobilized a third drill rig to the site in order to compress the timeline as much as possible. I see Ana Paula
as a foundational asset of the high-quality mid-tier producer we are growing towards.”
Drilling Program
Heliostar has added a third drill to accelerate the drilling pro gram and has completed 24 holes and 6,529
metres drilled to date. Drilling is designed along north-south sections with angled holes to best define the
overall east-west orientation of the High Grade Panel. Heliostar’s drilling approach at Ana Paula has been
to rotate drilling by approximately 90 degrees from the majority of historic intercepts . This change has
been interpreted by the Company to have contributed to demonstrating more continuous and higher-grade
gold mineralization within the High Grade Panel than previous operators recognized.
Where appropriate, the holes are also being used to collect rock strength data, hydrogeologic data and
samples for further metallurgical studies that will directly influence the Ana Paula mine design in the
ongoing Feasibility Study.
Drill Results Summary
Holes AP-25-327 and AP-25-329 are resource conversion holes drilled at the western end and the central
part of the High Grade Panel. Hole AP-25-327 was drilled along the western edge of the polymictic breccia
host unit and still returned a number of attractive intercepts, including 21.7 metres (“m”) grading 2.75

grams per tonne (“g/t”) gold in the Parallel Panel from 97.0 m and 20.5 m grading at 4.61 g/t gold from
198.8 m in the High Grade Panel.
AP-25-329 is located approximately 95m southeast of AP -25-327. It is the first north -to-south hole on a
new cross-section through the deposit. The hole intercepted the favourable breccia host unit and returned
a wide, high-grade interval of 88.05 m grading 8.82 g/t gold from 88.2 m through the core of the High Grade
Panel. A near -surface 12.75 m intercept of 3.28 g/t gold through the Parallel Panel has the potential to
expand the resource model to the surface.

Holes AP-25-326 and AP-25-328 are geotechnical holes for mine development planning and returned assay
results in line with expectations, including a hit of 23.0 m grading 2.86 g/t gold from 389.0 m in AP-25-326.
True widths are unknown. Mineralization at Ana Paula occurs as disseminations or vein stockworks with
variable controls including rock porosity, lithology and fault networks.
Drilling continues at the less well- defined western edge of the High Grade Panel , with results from four
additional holes pending from this area. Recently, drilling has been focused on the centre and eastern edge
of the High Grade Panel, with assays from twelve holes pending from this area.
The next Ana Paula drill results are anticipated to be released in early November.
