Heliostar Achieves Full-Year 2025 Production Guidance and Grows Cash to $41M

HIGHLIGHTS:

2025 Production of 34,098 GEOs (32,990 gold ounces and 80,527 silver ounces)

Cash balance of US$41M as of December 31, 2025

Heliostar Metals Ltd. (TSXV: HSTR,OTC:HSTXF) (OTCQX: HSTXF) (FSE: RGG1) (‘Heliostar’ or the ‘Company’) is pleased to announce that it produced 8,459 Gold Equivalent Ounces (GEOs) (8,180 gold ounces and 21,494 silver ounces) in the three months ended December 31, 2025.

This resulted in a total production in calendar year 2025 of 34,098 GEOs (32,990 gold ounces and 80,527 silver ounces). As a result, the Company achieved its production guidance for 2025 of 31,000-41,000 GEOs (see news release dated February 4, 2025). Financial results for the quarter and year ended December 31, 2025, will be reported during March 2026. Cash Costs and All-In Sustaining Costs (‘AISC‘) are expected to be within the guidance range.

As of December 31, 2025, the Company had a preliminary cash balance of US$41M and no debt. This provides a strong balance sheet for Heliostar’s 2026 growth initiatives, further supported by ongoing cash generated by operations.

 
Heliostar CEO, Charles Funk, commented, ‘This is a wonderful result for our first full year of gold production. Achieving our 2025 guidance was the result of the team successfully executing on the restart of operations at our two mines; La Colorada in January and San Agustin in December. The restart of San Agustin is expected to materially increase Heliostar’s year-on-year gold production in 2026, and we look forward to providing guidance for 2026 shortly. In addition to increasing production this year, we will be advancing Ana Paula through a feasibility study and recommencing the decline as we work toward our goal of becoming a 500,000 ounce per year producer by the end of the decade.’
