Heliostar Drills 8.85 Metres Grading 25.0 g/t Gold and
768 g/t Silver at the La Colorada Mine, Sonora, Mexico
HIGHLIGHTS:
• 8.85m grading 25.0 g/t gold and 768 g/t silver
• 8.55m grading 5.52 g/t gold and 121 g/t silver
• 3.5m grading 5.41 g/t gold and 87 g/t silver
• 5.5m grading 11.1 g/t gold
• 2.9m grading 10.5 g/t gold
• 4.6m grading 5.78 g/t gold
• 5.75m grading 4.72 g/t gold
• Higher-grade intercepts demonstrate underground potential beyond the current open pit
• The success of this drill program called for additional step-out drilling. Results for these
drill holes are expected in Q2, 2025
• La Colorada technical report update incorporating these results is expected in mid-2025
Vancouver, Canada – April 9, 202 5 – Heliostar Metals Ltd. (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG1)
(“Heliostar” or the “ Company”) is pleased to announce additional results from a 12,500-metre drilling
program at the La Colorada Mine in Sonora, Mexico. La Colorada restarted production in early January
2025, and the current drill program is intended to expand the mineral reserves ahead of an updated
technical report and expansion decision planned for mid-2025.
Heliostar CEO, Charles Funk, commented , “Heliostar closed the first quarter of 2025 with a US$27M
(C$38M) cash balance, over half of which was generated from operating profits. This places the Company
in a strong position to achieve our planned production and resource growth goals. Today’s results reflect
these growth plans and further cement our confidence in the future of La Colorada. They are expected to
positively impact the economics of the mine when we update the La Colorada technical report in mid-2025.
Our goal is for the study to support a decision to expand production to 50,000 to 100,000 ounces of gold per
year. Additionally, the high -grades intersected demonstrate a potential underground future for the mine.
We intend to target these deeper zones in more detail after we complete the technical report.”
Drill Results Summary
Mineralization at La Colorada’s Creston Pit is predominantly hosted in three veins: the North, Intermediate
and South Veins (Figure 1). These veins trend northeast -southwest to east-west, dip northward and are
surrounded by halos of smaller mineralized vein zones. The Creston Pit has historically mined oxide gold
and silver from all three of these veins. A current Probable Mineral Reserve of 312,000 ounces of gold
grading 0.76 grams per tonne (g/t) gold and 5,074,000 ounces of silver at 10.1 g/t silver is defined at the
Creston Pit1.
A technical review of expansion potential identified two opportunities for reserve growth. The near-surface
extensions of known veins with little or no drill data and exploring the under-sampled mineralization
beneath the pit. Both opportunities were defined using historical drilling, blast hole data, mining shapes,
and the geological model.

drilling and new Heliostar drill hole results below the planned pit boundary.
Blast hole data clearly shows the potential for a continuation of veins at shallow depths. They contain
elevated gold grades that continue to the edge of the pit walls, where they remain open for expansion

(Figure 1). At depth , drill spacing is wider than the area above. Additional drilling allows for improved
estimation of grade and continuity.
The Company has completed seventy-two holes totalling 11,075 metres in the program to date. This release
reports results for twenty-three new holes. The majority of the new drill holes targeted extensions of the
North, Intermediate , and South Veins in areas where drilling is widely spaced yet with in the current
resource. They aim to add ounces to the overall El Creston resources and reserves.
Assay results show narrow to wide, low - to high -grade oxide gold intercepts. Targeted vein zones
consistently return intercepts above the 0.16 g/t gold-equivalent cutoff grade of reserves within the Creston
pit. The results may increase the tonnes and grade of mineralization in an updated pit shell. If so, that would
add to the total reserves in an updated technical report.
Further, the success of the drill program to date has required modification of the remaining drill program
plans. Numerous step-out drill holes have been added to follow -up on intercepts reported here. Results
remain pending for these follow-up drill holes and are expected to be received in April and May.
Next Steps
Results from the current drill program are being incorporated into a resource model . They will support a
reserve update to be published with a technical report in mid-2025.
This drill program is important because if it increases the volume of rock containing gold mineralization, it
could improve the overall mine economics. Any zones of waste material with new gold intercepts from this
program have the potential to reduce the overall strip ratio of the Creston pit expansion.
That, in turn, could reduce the up-front capital requirements for the restart and improve the economics of
the Technical Report. This study will be the basis of a decision for the expansion of production at La
Colorada.
The Company anticipates additional drilling results from the current program will be released in Q2, 2025.

Quality Assurance / Quality Control
Core was drilled with PQ, HQ, and NQ tools, and the drill core was sawn in half, with one half submitted for
analysis and one half retained as a record. Core samples were shipped to ALS Limited in Hermosillo, Sonora,
Mexico, for sample preparation and for analysis at the ALS laboratory in North Vancouver. The Hermosillo
and North Vancouver ALS facilities are ISO/IEC 17025 certified. Gold was assayed by a 30-gram fire assay
with an atomic absorption spectroscopy finish, and overlimits were analyzed by a 30-gram fire assay with a
gravimetric finish.
Control samples comprising certified reference and blank samples were systematically inserted into the
sample stream and analyzed as part of the Company’s quality assurance / quality control protocol.

Cautionary Statement Regarding Forward-Looking Information
This news release includes certain "Forward–Looking Statements" within the meaning of the United States
Private Securities Litigation Reform Act of 1995 and "forward –looking information" under applicable
Canadian securities laws. When used in this news rel ease, the words "anticipate", "believe", "estimate",
"expect", "target", "plan", "forecast", "may", "would", "could", "schedule" and similar words or expressions,
identify forward –looking statements or information. These forward –looking statements or infor mation
relate to, among other things, this places the Company in a strong position to achieve our planned
production and resource growth goals. Today’s results reflect these growth plans and further cement our
confidence in the future of La Colorada. They are expected to positively impact th e economics of the mine
when we update the La Colorada technical report in mid-2025. Our goal is for the study to support a decision
to expand production to 50,000 to 100,000 ounces of gold per year. Additionally, the high grades intersected
demonstrate a potential underground future for the mine. We intend to target these deeper zones in more
detail after we complete the technical report. The Company anticipates additional drilling results from the
current program will be released in Q2, 2025.
Forward-looking statements and forward–looking information relating to the terms and completion of the
Facility, any future mineral production, liquidity, and future exploration plans are based on management’s
reasonable assumptions, estimates, expectation s, analyses and opinions, which are based on
management’s experience and perception of trends, current conditions and expected developments, and

other factors that management believes are relevant and reasonable in the circumstances, but which may
prove to be incorrect. Assumptions have been made regarding, among other things, the receipt of necessary

factors include, without limitation: precious metals price volatility; risks associated with the conduct of the
Company’s mining activities in foreign jurisdictions; regulatory, consent or permitting delays; risks relating
to reliance on the Company’s management team and outside contractors; risks regar ding exploration and
mining activities; the Company’s inability to obtain insurance to cover all risks, on a commercially reasonable
basis or at all; currency fluctuations; risks regarding the failure to generate sufficient cash flow from
operations; risks relating to project financing and equity issuances; risks and unknowns inherent in all mining
projects, including the inaccuracy of reserves and resources, metallurgical recoveries and capital and
operating costs of such projects; contests over title to p roperties, particularly title to undeveloped
