Heliostar Metals Ltd. (TSXV: HSTR,OTC:HSTXF) (OTCQX: HSTXF) (FSE: RGG1) ("Heliostar" or the "Company") is pleased to announce additional results from the current drill program at its 100% owned Ana Paula project in Guerrero, Mexico. The program's primary aim is to convert inferred ounces to higher confidence classifications. It will also support the ongoing Feasibility Study and test the next set of exploration targets near the current Ana Paula deposit.
Heliostar CEO, Charles Funk, commented, "During the reserve conversion drill program at Ana Paula, we decided to push a hole deeper to test for potential step-outs of the Expansion Zone. Hole AP-25-313A represents a 70 m step out from the nearest intercept supporting ore stopes and returned a strong interval of 25.45 m grading 8.26 grams per tonne gold. This is an exciting result from the Company's first hole beneath the High Grade Panel and based on this success, we have extended a number of additional holes deeper at Ana Paula. Two results from the Expansion Zone are reported today with the remaining assay results pending."
"We have always interpreted the resource to be open at depth as Ana Paula is geologically shallower than much larger gold deposits nearby. Due to the lack of drilling at depth, we don't have a strongly predictive model for mineralization within the Expansion Zone so hitting in this first step out is very encouraging. We continue to test this zone with our ongoing drill program and will release further results as we step out beyond the High Grade Panel within Ana Paula."
Drilling Program
Heliostar has completed 72 holes and 23,979 metres drilled to date in the current program. Today's release covers 13 holes with 34 holes awaiting assay results. Drilling is designed along north-south sections with angled holes to better define the overall east-west orientation of the High Grade Panel and the Expansion Zone beneath.
Where appropriate, the holes are also being used to collect rock strength data, hydrogeologic data and samples for further metallurgical studies. This data will allow Heliostar to further refine the mine design for Ana Paula in the ongoing Feasibility Study due to be released in the first half of next year.
Expansion Zone Drill Results Summary
Holes AP-25-313A and AP-25-345 are resource definition holes drilled along the western edge of the High Grade Panel and Expansion Zone. Hole AP-25-313A is an extension of AP-24-313 which had been drilled to the maximum depth of the core rig in 2024. The hole intersected 25.45 m of 8.26 grams per tonne ("g/t") gold from 493.8 m in an area that is currently outside of the proposed stopes in the November 2025 Preliminary Economic Assessment mine plan. Hole AP-24-345 was drilled from the same platform with a steeper dip. This hole intersected a 3.75 m zone of 5.00 g/t gold from 508.4 m depth. The interval is a 60 metre step out underneath and to the north of AP-24-313A and 20 m to the north of AP-11-76 (drilled by a previous operator) that returned 19.84 m at 3.33 g/t Au.
Mineralization is open to the north, northwest and beneath these intercepts.

True widths are unknown. Mineralization at Ana Paula occurs as disseminations and vein stockworks with variable controls including rock porosity, lithology and fault networks.
Drilling continues throughout the High Grade Panel, its less well-defined east and west edges, and into the Expansion Zone. Two of the drill rigs have continued to target deeper inferred mineralization and the northern exploration zone, which is approximately 250 m north of the High Grade Panel and that has ten drill holes pending assay.
The next Ana Paula drill results are anticipated to be released in four to six weeks.

Heliostar Metals Included In 2026 TSX Venture 50
Heliostar Metals is further pleased to announce that it has been included in the 2026 TSX Venture 50â„¢ list. The TSX Venture 50â„¢ is a ranking of the top fifty performing companies on the TSXV over the prior year and this is the second year in a row that Heliostar has been awarded the distinction.
TSX Venture 50 is an annual ranking of the top-performing companies over the last year on the TSX Venture Exchange, a world-leading capital formation platform for early-stage growth firms. The companies are ranked based on three equally weighted criteria of one-year share price appreciation, market capitalization increase, and Canadian consolidated trading value.
The Company takes pride in its share performance in 2024 and 2025 and the benefits that brings our shareholders. We believe our catalysts for 2026, including: 1) year-on-year gold production growth, 2) $27 million dollars in exploration programs, and 3) the advancement of key development projects including the Veta Madre pre-strip at La Colorada and the decline at Ana Paula, hold the Company in good stead to continue our share outperformance this year.
Quality Assurance / Quality Control
Drill core is PQ and HQ size, and the core is cut in half, with half sent for analysis. Core samples were shipped to ALS Limited in Zacatecas, Zacatecas, Mexico, for sample preparation and for analysis at the ALS laboratory in North Vancouver. The Zacatecas and North Vancouver ALS facilities are ISO/IEC 17025 certified. Gold was assayed by 30-gram fire assay with atomic absorption spectroscopy finish, and overlimits were analyzed by 30-gram fire assay with 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.

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, expectations, 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 approvals, price of metals; no escalation in the severity of public health crises or ongoing military conflicts; costs of exploration and development; the estimated costs of development of exploration projects; and the Company's ability to operate in a safe and effective manner and its ability to obtain financing on reasonable terms.
These statements reflect the Company's respective current views with respect to future events and are necessarily based upon a number of other assumptions and estimates that, while considered reasonable by management, are inherently subject to significant business, economic, competitive, political, and social uncertainties and contingencies.

Such 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 regarding 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 properties, particularly title to undeveloped properties; laws and regulations governing the environment, health and safety; the ability of the communities in which the Company operates to manage and cope with the implications of public health crises; the economic and financial implications of public health crises, ongoing military conflicts and general economic factors to the Company; operating or technical difficulties in connection with mining or development activities; employee relations, labour unrest or unavailability; the Company's interactions with surrounding communities; the Company's ability to successfully integrate acquired assets; the speculative nature of exploration and development, including the risks of diminishing quantities or grades of reserves; stock market volatility; conflicts of interest among certain directors and officers; lack of liquidity for shareholders of the Company; litigation risk; and the factors identified under the caption "Risk Factors" in the Company's public disclosure documents.
