Heliostar Announces First Gold Pour from San Agustin

Mine Restart

Vancouver, Canada, February 5, 2026 – Heliostar Metals Ltd. (TSX.V: HSTR, OTCQX: HSTXF, FRA: RGG1)

(“Heliostar” or the “Company”) is pleased to announce that the first official gold pour from restarted

mining operations at the Company’s 100% owned San Agustin mine occurred in late January 2026.

As announced on December 18, 2025, the Company resumed mining, crushing and stacking of new ore

on the leach pad in Q4 2025. We completed the restart on time and on budget. The operation continues

to ramp up successfully and has exceeded internal targets for ore mining rates and recoverable ounces

stacked on the pad to date. The mine is on track to meet production guidance of 30,000 -32,700 ounces

of gold in 2026.

Charles Funk, CEO , comments: “It is an extraordinary time in the gold market to bring new production

online. Bringing San Agustin online has increased our year -on-year consolidated production guidance by

over 60% whilst maintaining a low ~$2,000 AISC in 2026. At our 2026 budget gold price of $3,800 per

ounce, cash flow from San Agustin allows us to fund our company-wide exploration programs and capital

programs, including a pit expansion at La Colorada and decline development at Ana Paula. At current spot

prices, we can do all this and build our cash position more rapidly to help fund the Ana Paula CAPEX

planned for 2027/28. At San Agustin, the next key update will be results from the drill program targeting

mine life extension. These results are expected in mid-late Q1, 2026.”

expressions, identify forward–looking statements or information. These forward –looking statements or

information relate to, among other things, timing and economics of mineral production, ability to expand

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. Many factors, both known and unknown, could cause actual results,

information and the Company has made assumptions and estimates based on or related to many of these

factors. 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

the caption “Risk Factors” in the Company’s public disclosure documents. Readers are cautioned against

attributing undue certainty to forward–looking statements or forward-looking information. Although the

Company has attempted to identify important factors that could cause actual results to differ materially,

there may be other factors that cause results not to be anticipated, estimated or intended. The Company

does not intend, and does not assume any obligation, to update these forward –looking statements or

forward-looking information to reflect changes in assumptions or changes in circumstances or any other

events affecting such statements or information, other than as required by applicable law.

This news release includes certain non-International Financial Reporting Standards (IFRS) measures. The

Company has included these measures, in addition to conventional measures conforming with IFRS, to

provide investors with an improved ability to evaluat e the project and provide comparability between

projects. The non -IFRS measures, which are generally considered standard measures within the mining

industry albeit with non-standard definitions, are intended to provide additional information and should

not be considered in isolation or as a substitute for measures of performance prepared in accordance with

IFRS. Cash costs (Cash Costs) are a common financial performance measure in the gold mining industry

but with no standard meaning under IFRS. The Company believes that, in addition to conventional

measures prepared in accordance with IFRS, certain investors use this information to evaluate each

project’s economic results in the technical reports and each project’s potential to generate operating

earnings and cash flow. All -in Sustaining Costs (AISC) more fully defines the total costs associated with

producing precious metals. The AISC is calculated based on guidelines published by the World Gold Council

(WGC), which were first issued in 2013. In light of ne w accounting standards and to support further

consistency of application, the WGC published an updated Guidance Note in 2018. Other companies may

calculate this measure differently because of differences in underlying principles and policies applied.

Differences may also arise due to a different definition of sustaining versus growth capital. Note that in

respect of AISC metrics within the technical reports because such economics are disclosed at the project

level, corporate general and administrative expenses were not included in the AISC calculations.
