Heliostar Drills 30.2m grading 6.29g/t Gold in First
Resource Conversion Holes at Ana Paula
HIGHLIGHTS:
• 30.20m grading 6.29g/t gold from 195.8m
• 14.75m grading 13.6g/t gold from 153.5m
• 20.95m grading 6.67g/t gold from 113.5m
• 12.20m grading 8.72g/t gold from 344.5m
• Consistent gold mineralization at the western end of the High Grade Panel
• First results from a 15,000 metre program continuing throughout 2025
Vancouver, Canada – August 27, 2025 – Heliostar Metals Ltd. (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG1)
(“Heliostar” or the “ Company”) is pleased to announce its first 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 , “In 2025, Heliostar will drill more metres than we have in our
entire Compan y’s history. We intend to drill between 40,000 -50,000 metres from the close of the mine
acquisitions late last year to the end of 2025. This drilling is being funded by cashflows from our operating
mines. We are particularly excited to be undertaking our largest program at Ana Paula. The se first results
highlight the consistency of gold mineralization at the High Grade Panel , where we have two rigs turning.
One is focused on resource drilling to grow the resource and to convert inferred to higher confidence ounces,
and the second is with a geotechnical focus to support the Feasibility Study. These are the first of consistent,
drill results planned to be released monthly from Ana Paula through 2025 and into 2026.”
Drilling Program
Heliostar has two rigs turning with 18 holes completed and 5,556 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-25-323 and AP-25-325 are resource conversion holes drilled at the western end of the High Grade
Panel. Hole AP-25-323 was drilled further west than the most prospective polymictic breccia host unit and
still returned a number of attractive intercepts , including 12.2 metres (“m”) grading 8.73 grams per tonne
(“g/t”) gold from 344.5 m.

AP-25-325 is located ~30m southeast of AP-25-323 and intercepted the favourable breccia host unit. The
hole returned a wide, high -grade interval of 30.2 m grading 6.29 g/t gold from 195.8 m and a number of
deeper intercepts that have the potential to expand the resource , including 4.5 m grading 12.6 g/t gold
from 277.5 m downhole beneath the High Grade Panel.
Holes AP-25-322 and AP-25-324 are geotechnical holes for mine development planning and returned assay
results in line with expectations, including a hit of 14.75 m grading 13.6 g/t gold from 153.5 m in AP-25-322.
Drilling continues at the less well -defined western edge of the High Grade Panel , with results from three
additional holes pending from this area. Recently, drilling has been focused in the centre of the High Grade
Panel with assays from seven holes pending from this area.
The next Ana Paula drill results are anticipated to be released in mid- to late September.
