Heliostar Metals Ltd. (TSXV: HSTR) (OTCQX: HSTXF) (FSE: RGG1) ("Heliostar" or the "Company") is pleased to announce the first results from a 12,500 metre drilling program at the La Colorada Mine in Sonora, Mexico. La Colorada is currently producing gold from residual leaching having ceased mining in late 2023. Heliostar is reviewing the potential to restart mining in 2025 and is completing a drill program intended to expand the mineral reserve ahead of this decision.
HIGHLIGHTS:
- 5.0m grading 18.0 g/t gold
- 37.0m grading 1.24 g/t gold
- 11.8m grading 1.71 g/t gold
- 14.5m grading 1.69 g/t gold
- 10.1m grading 0.85 g/t gold
- Five drill rigs operating at site completing a 12,500m drill program
- Program designed to expand oxide mineral reserves at the El Creston pit
- Results show shallow mineralization is open and can positively impact mining economics
- Production decision at El Creston expected by mid-2025
Heliostar CEO, Charles Funk, commented, "La Colorada has long been a successful mine that helped build El Dorado Gold in 1990s and Argonaut Gold in the 2010s. It has operated profitably over its history and has reserves to support growth. Mining ceased in 2023 when stripping to expand the pit was not completed. This pre-strip is now a capital project and the opportunity to restart is a priority for Heliostar in 2025. Our team recognized that there are significant opportunities to expand shallow mineralization and today's results demonstrate the potential to convert a portion of the previously assumed waste into ore. This can result in lower capital costs and higher cash flow at the beginning of the restart. We value speed as a guiding business principle at Heliostar and have hit the ground running to deliver these results at the mine. I believe La Colorada will help build a third mining company over the next decade!"
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 all three of these veins. Drilling prior to Heliostar's acquisition of the mine had successfully focussed on these veins beneath the pit and had expanded the mineral reserve.
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 continuation of veins at shallow depth. It defines elevated gold grades continuing to the edge of the pit walls where they remain open for expansion.

Twenty-four holes are reported in this release for a total of 3257.1 metres, principally targeting shallow zones to the east and west of the Creston Pit. The results show narrow to wide, low to high grade oxide gold intercepts. They consistently return intercepts above the average above the mining cutoff of the pit while it was in operation and suggest that areas of waste could be converted to ore in an updated reserve model.
Next Steps
An updated technical report will be completed in January 2025 using the existing resource model at La Colorada. This report will not include the drill results presented in this press release. Results from the current drill program will be incorporated into a resource model and will support a reserve update that will be published with a feasibility study in mid-2025.
Should the drilling define a significant enough volume of gold mineralization, the results have the potential to reduce the capital requirements and improve the economics of the feasibility study. This study will be the basis of a construction decision for the restart of mining from the Creston Pit at La Colorada in mid-2025.
Drilling continues at the mine with three areas of focus. Additional shallow drilling, to follow up these results, is designed to bring production ounces forward in the mine plan. A program of infill and expansion drilling deeper in the pit will attempt to grow the overall gold reserves. A small allocation of drill metres will also test new areas of potential gold mineralization.
The Company anticipates additional drilling results from the current program will be released early next year.

These forward-looking statements or information relate to, among other things, the Company's plans, prospects and business strategies; the potential update and expansion of mineral reserves; the Company's integration of acquisitions and any anticipated benefits thereof; the completion of a Feasibility Study on the La Colorada Mine in 2025; the potential re-start of mining operations at the Creston Pit;; the release of an updated technical report on the La Colorada Mine; exploration and development plans, including drilling; and expectations for other economic, business, and/or competitive factors.
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. Many factors, both known and unknown, could cause actual results, performance, or achievements to be materially different from the results, performance or achievements that are or may be expressed or implied by such forward-looking statements or forward-looking 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 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. Readers are cautioned against attributing undue certainty to forward-looking statements or forward-looking information.
