HELIOSTAR DELIVERS STRONG FIRST QUARTER 2025 RESULTS

Heliostar Metals Ltd. has released preliminary interim results for the three months ended March 31, 2025, which corresponds to the fourth quarter of Heliostar's fiscal reporting year 2024/2025.

The company plans to host a corporate update webinar on May 13, 2025, at 8 a.m. PT (11 a.m. ET). Full fiscal year-end reporting is anticipated in late July, 2025.

Heliostar chief executive officer Charles Funk commented: "The first quarter of 2025 was a very strong, first full quarter of production for the company. We restarted production at La Colorada, fully paid off the acquisition debt and returned lower costs than budgeted.

"In Q2, production is expected to decrease due to drawdown of inventory on the leach pad at San Agustin prior to a planned restart of primary mining activities later in 2025. We remain well on track to meet our production and cost guidance for 2025.

"Heliostar exited the quarter with a strong cash balance of $27-million (U.S.). This allows us to expand the drilling program at La Colorada and commence the company's largest drilling campaign at our flagship Ana Paula project, where we see potential to increase the high-grade underground resource.

"Looking forward, in Q2, we are focused on delivering an updated technical report to support a planned increase in production at La Colorada, and completing the permitting to allow for the restart of mining at San Agustin. The company intends to utilize the cash flow from operations to increase annual gold production from both producing mines, as well as build Ana Paula with minimal equity dilution."
