Heliostar CEO, Charles Funk, commented, "At La Colorada, we are seeing the combined benefit of gold production at record prices and growth from the first significant investment into the project in many years. Our aggressive five-rig drill program is designed to increase the reserves of the Creston pit. Success to date in the shallow part of the pit could lower the upfront capital costs presented in the January 13th Technical Report. The Company will use the results of this drill program to finalize a Feasibility Study in mid-2025 and then make an expansion decision on La Colorada to 50,000-100,000 ounces per year of annual production. We are also hitting high grades and widths and deeper intercepts could drive underground mining optionality beyond the open pit. We will further test this target with additional drilling in this current drill program."
Drill Results Summary
Mineralization at La Colorada's Creston Pit is predominantly hosted in three veins: the North, Intermediate and South Veins (Figure 1). These veins trend northeast-southwest to east-west, dip northward and are surrounded by halos of smaller mineralized vein zones. The Creston Pit has historically mined oxide gold and silver from all three of these veins. A current Mineral Reserves of 312,000 ounces of gold grading 0.76 grams per tonne (g/t) gold and 10.1 g/t silver is defined at the Creston Pit1.
Reviewing the expansion potential revealed two opportunities for reserve growth: near surface extensions of known veins where little or no drilling had been completed and upgrading and expanding mineralization beneath the pit. Both opportunities were defined using historical drilling, blasthole data, mining shapes, and the geological model.
High-density blast hole data strongly emphasizes the potential for a continuation of veins at shallow depth, defining elevated gold grades that continue to the edge of the pit walls where they remain open for expansion (Figure 1).

Forty-seven holes have been completed in the program to date, with results reported for twenty-three new holes in this release. A total of 6,452 metres have been completed to date in the program. The majority of the new drill holes targeted shallow extensions of the North, Intermediate and South Veins in areas considered to be waste in the reserve estimate of the current Technical Report. Additionally, today's results include deeper holes beneath the current pit. These holes target the growth of reserves deeper within the planned pit expansion. They aim to add ounces to the overall El Creston resources and reserves.
The results show narrow to wide, low to high-grade oxide gold intercepts. They consistently return intercepts above the 0.16 g/t gold cutoff grade of reserves within the Creston pit. The results suggest that areas of waste could be converted to ore in an updated reserve model.
High-grade intercepts deeper in the pit indicate the potential for mineralization that may be amenable to underground mining beyond the current pit boundary. The Company will follow-up on these results to assess the potential to extend mine life with mineralization amenable to underground mining beneath and to the west of the Creston Pit.
Next Steps
Results from the current drill program will be incorporated into a resource model and support a reserve update to be published with a Feasibility Study in mid-2025.
Should the drilling define a material volume of gold mineralization, this program has the potential to reduce the overall strip ratio of the Crestón pit expansion, which could result in a reduction in up-front capital requirements for the restart and improve the economics of the Feasibility Study. This study will be the basis of a decision for the expansion of production at La Colorada in mid-2025.
The Company anticipates additional drilling results from the current program will be released in Q1 and Q2, 2025.

Quality Assurance / Quality Control
Core samples were shipped to ALS Limited in Hermosillo, Sonora, Mexico, for sample preparation and for analysis at the ALS laboratory in North Vancouver. The Hermosillo 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 analysed 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.

These forward-looking statements or information relate to, among other things, Continued success from assay results from shallow drilling in areas considered to be waste within the Creston Pit Expansion, Higher Grade intercepts demonstrate underground potential beyond the current open pit, the benefit of gold production at record prices, growth from the first significant investment into the project in many years, success to date in the shallow part of the pit could lower the upfront capital costs presented in the January 13th Technical Report, the Company will use the results of this drill program to finalize a Feasibility Study in mid-2025 and then make a decision to expand La Colorada to 50,000-100,000 ounces per year of annual production, hitting high grades and widths deeper intercepts could drive underground mining optionality beyond the open pit.
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.
