Vancouver, British Columbia--(Newsfile Corp. - January 13, 2025) - Heliostar Metals Ltd. (TSXV: HSTR) (OTCQX: HSTXF) (FSE: RGG1) ("Heliostar" or the "Company") advises that it has filed technical reports on the La Colorada Operations, the San Agustin Operations and the San Antonio Project. The technical reports were prepared on material projects acquired in 2024.
The technical reports are available on SEDAR+ (www.sedarplus.ca) and on the Company's website (www.heliostarmetals.com).
Heliostar CEO, Charles Funk, commented "Heliostar has filed technical reports for three of its recently acquired Mexican projects. At La Colorada, we have restarted production this month with 2025 focused on the newly defined Junkyard Stockpile and then expanding to over 50,000 ounces of gold per year with the El Crestón expansion. At San Agustin, the Phase 4 Permit area can generate strong cash flow and reduce closure costs. More importantly receiving expansion permits will provide the trigger to restart drilling, targeting further mine life expansion at the mine which has upside oxide and sulphide potential. The PEA at San Antonio demonstrates a rare, 1.0 Au g/t heap leach deposit with low CAPEX, low ASIC and a long mine life. It provides attractive optionality for our long-term growth. The combined projects have positive economics at conservative gold prices and significantly stronger returns at today's gold prices. In 2025, the Company will focus on reducing front-end capital requirements for El Crestón to improve the project economics for the expansion decision and will continue to advance Ana Paula through its Feasibility Study."
LA COLORADA MINE
Mineral Resource and Mineral Reserve estimates and a life-of-mine (LOM) plan were completed for the 100% owned La Colorada Operations (La Colorada) located in the state of Sonora, Mexico. The LOM plan in the La Colorada technical report is based on continued production from three sequentially-staged deposits: the Junkyard Stockpile (La Chatarrera), the El Crestón pit expansion (El Crestón), and the Veta Madre pit expansion (Veta Madre). The La Colorada technical report that is the subject of this news release supersedes a technical report that was prepared on the La Colorada Mine by Argonaut Gold Inc., which had an effective date of October 1, 2021.
The La Colorada technical report includes first-time disclosure of a Mineral Resource and Mineral Reserve estimate for the Junkyard and updated Mineral Resource and Mineral Reserve estimates for El Crestón and Veta Madre. The LOM plan indicates a Probable Mineral Reserve of 377k ounces of gold exploited with two years of pre-strip and 4.1 years of mine life, from the effective date of the La Colorada technical report, at production rates up to the 13,000 t/d nameplate throughput capacity of the mine at an all-in sustaining capital cost of US$1,763/oz Au.

- Mineral Reserves have an effective date of 30 November 2024. The Qualified Person for the estimate is Mr. Jeffrey Choquette, P.E., of Hard Rock Consulting.
- A 0.16 g/t AuEq cut-off is used for reporting the Mineral Reserves at El Crestón, and a 0.175 g/t AuEq cut-off is used for reporting Mineral Reserves at Veta Madre. Cut-offs were calculated based on a gold price of US$1,900/oz Au, silver price of US$23/oz Ag, processing costs of US$5.87/t, general and administrative costs of US$1.15/t, refining and selling costs of US$0.66/t, gold recovery of 79% for El Crestón and 72% for Veta Madre and a silver recovery of 13% for El Crestón and 9% for Veta Madre. The AuEq cut-off for the Junkyard Stockpile is 0.164 g/t AuEq based on metal prices of US$1,900/oz Au, and US$23/oz Ag, processing costs of US$4.82/t, general and administrative costs of US$1.15/t, refining and selling costs of US$0.66/t, gold recovery of 66% and a silver recovery of 27%. The AuEq calculation uses the formula AuEq = (Au + Ag/equivalency factor) where equivalency factor = ((Au price in US$/g * Au recovery) / (Ag price in US$/g * Ag recovery)).
- Mineral Reserves are reported within the ultimate reserve pit design. An external dilution factor of 10% and a metal loss of 5% were factored into the Mineral Reserves estimates.
- Tonnage and grade estimates are in metric units.
- Mineral Reserve tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.
The LOM plan outlines sequential exploitation of the three deposits with two years of pre-production from the Junkyard (2025) and from near-surface ore extracted during pre-stripping (2026), before a production LOM of 4.1 years.

Metal Prices
The La Colorada technical report includes a sensitivity analysis for key parameters impacting the forecast economic returns for La Colorada. The LOM plan and Mineral Reserves estimates are most sensitive to changes in the gold price, and gold grade. Since silver is projected to contribute only about 4% to the revenues. LOM variations in the silver price have limited impact on the cashflow forecast. The LOM plan and Mineral Reserves estimates are less sensitive to operating cost changes, and least sensitive to changes in capital costs.

Commentary by the Company on Relevant Matters
The results from ongoing drilling and other technical studies being performed at El Crestón are excluded from the La Colorada technical report but will be incorporated into a mineral resource model and will support a Mineral Reserve update that will be published with an updated technical report in mid-2025.
A total initial capital of $53.9M is a required, predominantly from waste stripping prior to the reaching the life-of-mine strip ratio. Further stripping is required after reaching the life-of-mine strip ratio and a maximum negative cash flow of US$139 million is projected at the base assumptions used in the La Colorada technical report (US$117M at US$2,600 gold).
The La Colorada technical report presents cash flows based on the base gold price used. With exploitation of the Junkyard starting this month, the project will generate revenues from sales based on current gold prices which are expected to be higher than the base gold price used in the La Colorada technical report.
The gold market has experienced significant upward price movement in the past few years and, considering that the gold price at the effective date of the La Colorada technical report is about 34% above the base gold price used in the La Colorada technical report. The sensitivity analysis presents gold price scenarios up to US$3,000/oz Au to understand the potential impact. From the base case price of $2,000/oz (years 2026-2031), a change in the average gold price of US$200/oz Au would change the NPV at a 5% discount rate by 108%, or approximately $28.0 M
Commentary by the Company on Next Steps and Permitting
Restart of mining activities at La Colorada has commenced at the Junkyard this month. The Company will provide production and cost guidance for 2025 later in January.
The Company will be continuing the current drill program and conducting other technical programs at El Crestón and plans to complete updated technical study in mid-2025.
The drill program includes shallow infill drilling designed to support short-term mine planning, and a program of infill and expansion drilling deeper in the pit to include in the future update to Mineral Resource and Mineral Reserve estimate.
Some ancillary permitting work is planned at El Crestón and is expected to be completed by mid-2025. A change of land use permit is required to enable exploitation of Veta Madre.
Since the development plan for La Colorada represents a continuation of the historical operations, minimal capital investment is required for new equipment and facilities; however, pre-stripping at El Crestón and Veta Madre will need to be financed. Subject to satisfactory conclusion of the planned work programs and arranging financing, the Company is anticipating making an investment decision at El Crestón in 2H 2025.

San Agustin Mineral Reserve Estimates
The Mineral Reserve estimate at San Agustin is based on operation of the existing crusher and conveyor system having a nameplate throughput capacity of about 30,000 t/d and continued operation of the heap leach and CIC process circuit to processing ore from the expanded open pit. The Mineral Reserve estimate is presented in the following table.

Notes to accompany Mineral Reserves table:
- Mineral Reserves are reported at the point of delivery to the process plant, using the 2014 CIM Definition Standards.
- Mineral Reserves have an effective date of 30 November 2024. The Qualified Person for the estimate is Mr. Jeffrey Choquette, PE, of Hard Rock Consulting, LLC.
- A 0.156 g/t AuEq cut-off is used for reporting the Mineral Reserves in oxide, and a 0.310 g/t AuEq cut-off is used for reporting Mineral Reserves in transitional material. Cut-offs were calculated based on a gold price of US$1,900/oz Au, silver price of US$23/oz Ag, processing costs of US$4.23/t for oxide, processing costs of US$5.14/t for transitional, general and administrative costs of US$1.40/t, refining and selling costs of US$0.66/t, gold recovery of 66% for oxide and 38% for transitional and a silver recovery of 10% for oxide and transitional. The AuEq calculation uses the formula AuEq = (Au + Ag/equivalency factor) where equivalency factor = ((Au price in US$/g * Au recovery) / (Ag price in US$/g * Ag recovery)).
- Mineral Reserves are reported within the ultimate reserve pit design. An external dilution factor of 5% and a metal loss of 3% have been factored into the Mineral Reserve estimate.
- Tonnage and grade estimates are in metric units.
- Mineral Reserve tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding

Metal Prices
The San Agustin technical report includes a sensitivity analysis for key parameters impacting the forecast economic returns for San Agustin. The LOM plan and Mineral Reserves estimates are most sensitive to gold price and gold grade. Since silver is projected to contribute only about 9% to the San Agustin revenues, variations in the silver price have a small impact on the cashflow forecast. The LOM plan and Mineral Reserves estimates are less sensitive to operating cost changes, and least sensitive to changes in capital costs.

Commentary by the Company on Relevant Matters
The San Agustin technical report presents cash flows based on the base gold price used. With exploitation of the Mineral Reserve as presented in the San Agustin technical report, the project will generate revenues from sales which may be higher than the base gold price used in the San Agustin technical report.
The gold market has experienced significant upward price movement in the past few years and, considering the gold price at the effective date of the San Agustin technical report is about 34% above the base gold price used in the San Agustin technical report. The sensitivity analysis presents gold price scenarios up to US$3,000 per ounce to understand the potential impact. From the base case price of $2,100/oz, a 10% change in the average gold price (or US$210/oz Au) would change the NPV at a 5% discount rate by 42%, or approximately $5.3 M.
Commentary by the Company on Next Steps and Permitting
Although mining activities at San Agustin ceased in August 2024, the Company is continuing re-leaching activities. The Company will provide production and cost guidance for 2025 later in January.
A change of land use permit is required to enable exploitation of the Mineral Reserve at San Agustin. Subject to obtaining the permit, the Company plans to conduct a small, in-fill drill program to provide geotechnical information and support short-term mine planning, and to complete other preparation work needed to restart the mining activities. These activities are expected to require 4-6 months to complete from permit approval.

SAN ANTONIO PRELIMINARY ECONOMIC ASSESSMENT
A Preliminary Economic Assessment (PEA) based on Mineral Resource estimates was completed for the 100% owned San Antonio Project (San Antonio Project technical report) located in the state of Baja California Sur, Mexico. The study considers construction and operation of a greenfield open pit and heap leach-CIC mine operation. The San Antonio Project technical report that is the subject of this news release supersedes a technical report that was prepared on the San Antonio Project by Argonaut Gold Inc., which had an effective date of 1 September, 2012.
The PEA is preliminary in nature and includes Inferred Mineral Resources that are too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the preliminary economic assessment will be realized.

Commentary by the Company on Relevant Matters
The gold market has experienced significant upward price movement in the past few years and considering gold price at the effective date of the San Antonio technical report is about 41% above the base gold price used in the San Agustin Project technical report. The sensitivity analysis presents gold price scenarios up to US$3,000 per ounce to understand the potential impact. From the base case price of US$1,900/oz Au, a change in the average gold price of US$200/oz Au would change the NPV at a 5% discount rate by 22.7%, or approximately $90.4 M.
Commentary by the Company on Next Steps and Permitting
The Project requires further development planning and engineering. All major environmental and other permits will need to be obtained before an investment decision can be considered by Heliostar.
Based on the results from the San Antonio Project technical report, the Company will conduct a strategic Project review with the objective of identifying and evaluating the next development steps and challenges. The Company will also consider additional work programs and alternative business possibilities to potentially add Project value to the San Antonio Project as presented in the PEA. This strategic review is expected to require 3-4 months to complete.

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. 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 evaluate 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 new 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.
