Heliostar Metals Ltd. (TSX: HSTR,OTC:HSTXF) (OTCQX: HSTXF) (FSE: RGG1) ("Heliostar" or the "Company") is pleased to announce additional results from drilling at its 100% owned San Agustin Mine in Durango, Mexico. This is part of the Company's ongoing resource and exploration drilling programs, which have been further increased to 25,000-30,000 metres of drilling based on success to date. The program has the primary aim of finding additional oxide resource ounces to support an extension of the mine life.

Heliostar CEO, Charles Funk, commented, "Today's results build on the positive exploration results reported earlier this year. Drilling has defined multiple zones, including the Corner Extension and newly reported East Wall zones that have similar grades and widths to gold mineralization that is currently being mined. Resource modelling, metallurgical assessment, engineering design and permit modifications are ongoing at these two zones, and we expect that they can provide 50% of the targeted two-year additional mine life at San Agustin. The Company doubled the size of the ongoing drill program to follow up open mineralization and test additional targets to complete the expansion objective in 2027. Achieving this target would meaningfully increase the Company's cash-flow generation as we bring Ana Paula into production."

Drilling Program

Heliostar has completed 217 holes and 22,118 metres to date in the current program that is testing nine near-mine target areas. Today's release covers results from 164 holes totalling 16,970 metres from four of the nine target areas, namely the Corner Expansion, Phase 3 East, Phase 5 and the East Wall zones (Figure 1).

Results demonstrate the potential for production growth and mine life extension at San Agustin. Intercepts at the Corner Expansion Zone show mineralization over 200 metres southwest of the edge of the current reserve that remains open. Drilling at the newly identified East Wall Zone also demonstrates that mineralization on the southeast edge of the pit is open to the east beyond the current reserve. Exploration drilling at both the Phase 5 and Phase 3 East zones has returned results that warrant follow-up drilling.

Encouraging results at the Corner Expansion Zone have driven the decision to expand the US$9.75 million drill program to define the full extent of additional resource targets. The expansion of the program to 25,000-30,000 metres will allow for a resource drilling program to follow up on results received to date and first-pass testing of the MKT-2, La Isla, and Phase 7 Oxide Target zones. A number of sulphide targets underlying the oxide mineralization are also being tested. Drilling is being undertaken with two drill rigs, a reverse circulation ("RC") rig for resource definition drilling and a core drill rig to collect resource information and additional rock strength data, hydrogeologic data and samples for detailed metallurgical studies. This will allow Heliostar to gather the engineering and metallurgical information required to evaluate an additional pit layback beyond the reserve that is currently being mined.

Corner Expansion Zone Results Summary

The Corner Expansion Zone drilling continues to demonstrate that mineralization extends beyond the current Corner Reserve. A mineralized corridor extending 200 metres away from the current pit boundary is defined by previously reported intercepts in 25-SAGRC-739, -740, and -746 and further supported by holes 26-SAGDD-014 and -016 reported today. This corridor remains open to further expansion (Figure 1).

Mineralization in the corridor is principally controlled by the southwest-striking Arturo fault with secondary controls including favourable lithologies and lithologic contacts. Additional definition drilling using both core and RC has increased the drilling density to support a resource model ahead of a mining decision. The extension of the Arturo Fault mineralization has been a focus of drilling, with multiple successful exploration intercepts along the structure. However, new intercepts in holes 25-SAGRC-795 and -796 represent an additional corridor of higher-grade ore that is further south within the Corner Expansion Zone. These intercepts demonstrate a second open zone of mineralization that the Company intends to follow up on.

East Wall Zone Results Summary

Drilling at the newly defined East Wall Zone intersected high-grade northeast-striking mineralized corridors and disseminated mineralization along the eastern margin of the existing pit. Key intercepts include 26-SAGRC-810 and -815, which intercepted 94.5 m at 0.33 grams per tonne ("g/t") gold equivalent ("Aueq") from surface and 100.6 m of 0.42 g/t Aueq from surface, respectively (Figure 2).

Intercepts at the East Wall Zone have defined a corridor where northeast-striking structures and intrusive-sediment contacts are controls on mineralization. This mineralization extends 150 metres east from the wall of the pit and current reserve and remains open.

Results Details

True widths are unknown. Mineralization at San Agustin occurs as disseminations and structurally and stratigraphically controlled zones. Multiple controls on these zones include northwest- and northeast-striking sub-vertically dipping faults, lithology, and fracture networks. Drill orientation is optimized to test the dominant control in the area.

Next Steps

Drilling remains ongoing at San Agustin and will continue to explore for new mineralization as well as follow-up areas of interest with resource definition drilling.

At the Corner Expansion and East Wall zones, the Company is advancing a resource and reserve estimate supported by detailed metallurgy and engineering. Completion of this work will define an updated reserve that will support submission of permit modifications. Upon receipt of the necessary permit modifications and technical information, the Company will be able to make a decision on the extension of the mine life of San Agustin.

High-Quality Development Pipeline: Cerro del Gallo targeting 86,000 GEO/year at US$1,390 AISC, alongside San Antonio’s production potential.
Strategic Expansion in the US: Acquisition of the Goldstrike project in Utah adds near-surface oxide potential and long-term growth optionality.
Strong Institutional Backing: Approximately 53 percent institutional ownership, complemented by high-net-worth investors and management alignment.

Key Projects

Ana Paula (Flagship Development Project)

$Heliostar Metals \u200bAna Paula Project$

Ana Paula is a high-grade underground gold project in Guerrero and the cornerstone of Heliostar’s long-term growth strategy.

The November 2025 PEA outlines a 9 year mine life with 101,000 oz/year production, 874,700 oz total output, and strong economics, including a US$1,012M NPV5% and a 51.3 percent IRR, supported by a low AISC of US$1,011/oz.

The project hosts approximately 742,000 oz measured and indicated at 5.4 g/t and 514,000 oz inferred, highlighting its high-grade profile and expansion potential.

Heliostar Metals Guerrero Gold Belt

With a feasibility study targeted for H1 2027 and construction expected in H2 of the same year, Ana Paula is expected to become the primary driver of Heliostar’s transition to mid-tier production.

The company is targeting production at Ana Paula in 2028.

La Colorada Mine

$Heliostar Metals \u200bLa Colorada Mine$

La Colorada in Sonora is a key cash-flowing asset that underwent a successful turnaround in 2025. The mine hosts reserves of 376,000 ounces of gold grading 0.68 g/t in 17.1 million tonnes of ore.

The mine is expected to produce 20,000–22,300 oz in 2026 at AISC of US$1,775–1,875/oz, supported by a six-year mine life and approximately 286,000 oz total production profile.

Mining at the project’s Veta Madre pit commenced in August 2026, a milestone that the company ties to its plan to secure cash flow through 2027 and 2028 to support construction at Ana Paula.

Ongoing drilling, pit expansions and underground potential provide meaningful upside, reinforcing its role as a core funding engine for development.

Heliostar Metals 2026 Guidance

San Agustin Mine

San Agustin in Durango is a restarted oxide heap-leach operation providing near-term production growth and cash flow.

2026 guidance targets 30,000–32,700 oz of gold at AISC of US$2,150–2,250/oz, following a low-capital restart funded from the company’s balance sheet.

The asset offers additional upside through oxide expansion and sulphide exploration, supporting potential mine life extension.

Cerro del Gallo Project

Cerro del Gallo is a large-scale gold-silver development project in Guanajuato and a key driver of future production growth.

The 2025 PFS outlines ~86,000 GEO/year over a 15-year mine life at US$1,390 AISC, with strong economics, including US$972 million NPV5% and 59.3 percent IRR at higher gold price assumptions.

The project is expected to play a central role in advancing Heliostar towards the goal of 500,000 oz annual production by 2030.

San Antonio Project

San Antonio is a 100%-owned heap-leach development project offering strong optionality and long-life production potential.

The project hosts approximately 1.74 million ounces of measured and indicated gold and demonstrates attractive optionality, including potential 80,000 oz/year production and low AISC of US$1,063/oz.

As permitting advances, San Antonio represents a key medium-term growth opportunity within the portfolio.

Goldstrike Project (Utah, USA)

Goldstrike is a newly acquired gold project that expands Heliostar’s footprint in the United States and adds exploration and development optionality. The property currently hosts an Indicated resource of 975 kilo ounces at 0.46 g/t of gold.
