Heliostar Metals Ltd. (TSXV: HSTR,OTC:HSTXF) (OTCQX: HSTXF) (FSE: RGG1) (‘Heliostar’ or the ‘Company’) today reported unaudited financial results for the three months ended September 30, 2025 (‘Q3 2025’), which corresponds to the second quarter of Heliostar’s fiscal reporting year 2025. Results are presented in US dollars, unless stated.

Heliostar CEO, Charles Funk, commented, ‘In Q3, Heliostar continued to generate strong cash flow from our operating mines. We grew production and strengthened our capital position while significantly reinvesting across the portfolio. In Q3, this included significant drill programs at Ana Paula and La Colorada, economic studies for La Colorada and Ana Paula as well as permissions and preparations to restart mining at San Agustin. Our strong cash balance has allowed us to internally fund this restart. This gives us a clear path to generate cash flow from operations which will fund the ongoing development of Ana Paula with little-to-no equity dilution.’

‘Our recently released PEA for Ana Paula shows that the additional 101,000 ounces per year of production at an all-in sustaining cost of just $1,011/oz will be a significant cash flow generator for Heliostar, supporting growth through the next decade. The cash generated by being a producer in the current gold price environment affords us opportunities to accelerate our plan to become a mid-tier producer with 500,000 ounces per year before the end of the decade.’

Third Quarter 2025 Quarterly Conference Call

Heliostar will host a quarterly conference call on Monday, November 24, 2025, at 2:00 PM, Eastern Time/11:00 AM Pacific Time. The call will provide a corporate update following the release of our financial and operating results for the third quarter of 2025.

Q3 2025 Operational and Financial Highlights

Total gold production of 9,165 gold equivalent ounces (‘GEO’) (8,949 gold ounces) in Q3 2025. Gold production was realized from mining the Junkyard Stockpile at the La Colorada mine, as well as re-leaching the previously stacked ore at the La Colorada and the San Agustin mines. Production year-to-date January – September 2025 (‘YTD’) remains on track to achieve the lower half of the 2025 guidance issued by the Company on February 4, 2025, of 31,000-41,000 GEOs.

Total Cash Cost of $1,500 per GEO produced in Q3 2025. The combined YTD cash cost (see ‘Non-IFRS Measures’) is $1,405 per GEO.

Total AISC of $1,825 per GEO sold in Q3 2025. The increase from Q2 reflects a change in calculation methodology to include corporate General and Administrative (‘G&A’) and stock based compensation costs, expensed exploration incurred in the period, and remove previously-included by-product credits. The higher AISC is also a function of fewer GEOs sold in the period compared to Q2 2025. The consolidated YTD AISC (see ‘Non-IFRS Measures) is $1,799 per GEO sold.

Total Cash Costs and AISC are below the 2025 guidance range due to higher production relative to the budget. The Company anticipates materially higher costs in Q4 due to one-off sustainable capital investment incurred to restart mining from the Corner Area. These expenses are anticipated to return to lower rates in early 2026 at San Agustin.

Mine Operating Earnings of $14.2 million in Q3 2025. The Company continued to report strong results in Q3 2025 with steady operating unit costs and operating margin benefiting from selling into a rising gold market. Mine operating earnings YTD 2025 are $40 million.

Net income attributable to shareholders of $1.3 million, or $0.01 per share, for Q3 2025. Net income of $1.3 million ($0.01 per share) for Q3 2025 compared to a net income attributable to shareholders of $1.9 million ($0.01 per share) for Q2 2025. This was due to the increased exploration expense as drilling activities at Ana Paula ramped up and lower GEO sales volume in the quarter.

Strengthened financial position and liquidity: On September 30, 2025, the Company had cash of $34.6 million and working capital (defined as current assets less current liabilities) of $46.7 million. The cash position decreased compared to Q2 due to the increase in exploration spending. As of September 30, 2025, the Company had 1,688 unsold ounces (worth approx. $6.9M at current spot gold prices) and no debt.

Maintained stable production at La Colorada mine. The mining of new ore restarted at the Junkyard Stockpile in January 2025. Production from the Junkyard Stockpile was steady during Q3 2025, with operating costs as expected, grade in line with the reserve model and ore tonnes reconciling slightly higher than expected. Production YTD 2025 was 13,328 GEOs (12,883 gold ounces). Ore feed from the Junkyard Stockpile is planned to continue into 2026, with other historical stockpiles identified to provide additional material to be crushed and stacked on the leach pad thereafter. Further, subject to receiving certain land access approvals, the Company intends to expand the Veta Madre pit to exploit its 43k ounces of gold reserves. In addition, drilling is ongoing at Veta Madre Plus with the aim of adding this additional Indicated material into a near-term mine plan in short order.

Restart of mining at San Agustin. Preparation work to commence mining is underway at San Agustin from the Corner area following the receipt of all necessary approvals to restart mining in Q3. The Company anticipates stacking first ore in December with production from the Corner starting near year end and continuing into 2027. Recoverable reserves at the Corner are estimated at 44.5k ounces of gold.

Strong economics and continued drilling success at Ana Paula drive additional investment. On November 6, 2025, the Company announced the results of a Preliminary Economic Study (PEA) for Ana Paula. These showed attractive economics at a conservative gold price driven by production of 101koz/yr after ramp up at an average all-in sustaining cost of $1,011/oz. On the back of this positive outcome, the Company has announced its intention to complete the underground decline access to the deposit in 2026. Technical and regulatory programs are being advanced in parallel and will continue through 2026 to complete a bankable feasibility study in early 2027.

Preparation of updated technical reports. The Company announced the results of an updated technical report for the La Colorada Mine on October 17, 2025, and is concluding an updated prefeasibility study (‘PFS’) for the Cerro del Gallo Project. The Company plans to release the results of the Cerro del Gallo PFS in Q4 2025 and continues to advance the Ana Paula Project feasibility study.

Operational and Financial Results

Results are reported for the three months ended September 30, 2025, which corresponds to the second quarter of Heliostar’s fiscal reporting year 2026.

A summary of the Company’s consolidated operational and financial results for the reporting period is presented below:

Operational Review

Consolidated Production and Costs

Q3 2025 was the Company’s fourth reporting period with metals production. The Company had no production in Q3 2024.

Production of 9,165 GEOs (8,949 gold ounces) for Q3 2025 was reported from the La Colorada mine and the San Agustin mine. In late Q2, the El Castillo mine ceased production and reclamation commenced at the start of Q3. The combined YTD 2025 production of 25,642 GEOs (24,988 gold ounces) is consistent with the 2025 guidance issued by the Company. Heliostar is on track to achieve the lower half of the 2025 production guidance of 31,000-41,000 GEOs with the several week delay in being able to restart San Agustin pushing production from that asset into 2026.

The combined cash costs for the producing operations were $1,500 per GEO sold, and the consolidated AISC was $1,825 per GEO sold. The combined cash costs and AISC are currently in line with the 2025 guidance issued by the Company. Full-year results are expected to be within the guidance range of $1,800-$1,950/GEO for Cash Costs and $1,950-$2,100/GEO for AISC.

La Colorada Mine

Operating results for Q3 2025 were as follows:

In January 2025, mining of new ore restarted at the Junkyard Stockpile by the Company, alongside re-leach activities of ore stacked by previous operators.

During the reporting period, the La Colorada mine produced 5,479 GEOs (5,311 gold ounces). Total revenues of $14.7 million were reported from sales of 4,229 GEOs. The increase in production compared to Q2 was driven by higher grades placed on the leach pad and the first full quarter of solution flow from the leach pad after restart of operations. Production from the leach pad has increased steadily throughout the year and continues to meet all expected parameters.

For the reporting period, cash costs were $1,592 per GEO ($1,354 per GEO YTD 2025). AISC was $1,648 per GEO ($1,439 per GEO YTD 2025), on track to be at the lower end or below 2025 AISC guidance of $1,850-$1,975/GEO.

The Company plans to continue mining of the Junkyard Stockpile through 2025 and into 2026, with other historical stockpiles identified to provide additional, continued feed to the crushers thereafter. Further, subject to receiving certain land access approvals, the Company intends to expand the Veta Madre pit to exploit 43k ounces of gold reserve, which will be timed sequentially with the ore feeds from the historical stockpiles. Drilling is ongoing to define the mineralization at Veta Madre Plus, with the aim of bringing it into the near-term mine plan in short order.

Subsequent to the reporting period, Heliostar released the results of an updated technical report for La Colorada showing and increased resource and a lower capital expenditure. This showed a mine with a six-year life producing 286k gold ounces at an AISC of $1,626 per GEO. This resulted in upside case economics of an NPV5% of $243.3M and an IRR of 168.4% at a $3,500/oz gold price. For more details, see the press release here.

San Agustin Mine

Operating results for Q3 2025 were as follows:

In September 2024, the previous owners of San Agustin placed the mine under care and maintenance, with metals production continuing from the re-leaching of leach pads.

During the reporting period, the San Agustin mine produced 3,686 GEOs (3,638 gold ounces). Total revenues of $12.1 million were reported from sales of 3,480 GEOs. Re-leaching performance continued well above expectations in the quarter as a result of enhanced recovery initiatives conducted earlier in the year. Gold production through the first nine months of the year exceeded full-year 2025 guidance for re-leaching from the mine.

For the reporting period, cash costs were $1,389 per GEO ($1,437 per GEO YTD 2025). AISC was $1,587 per GEO ($1,546 per GEO YTD 2025), YTD on track to achieve full year AISC guidance of $1,700-$1,850/GEO.

During the quarter, the Company completed all regulatory requirements to enable the restart of mining at San Agustin from the Corner area (see News Release dated July 22, 2025). Work to commence mining of the Corner Area cut back was undertaken subsequently, including moving road access, a power line and contractor selection. First ore is on track to be stacked on the leach pad in the coming weeks. Initial gold production from this new material is expected to start near year end 2025 and continue into 2027. Recoverable reserves at the Corner are estimated at 44.5k ounces of gold.

Ana Paula Project

Development and Exploration expenditures at the flagship Ana Paula Project were $3.9 million in Q3 2025 ($1.8 million in Q3 2024).

During Q3 2025, the Company progressed its ongoing 15,000 metre drilling program at Ana Paula with the objective of delivering mineral reserves to support a 10-year life of mine in the Feasibility Study planned to be released in 1H 2027. On October 6, 2025, the Company announced results from the infill drill program (including 88.1m metres at 8.82 g/t) and the addition of a third rig. Subsequent to quarter end on November 18, 2025, the Company announced additional infill results of 83.2m of 17.4 g/t and 70.7m of 9.38 g/t. The drill program continues to successfully define wide zones of high grade mineralization.

Subsequent to the reporting period, Heliostar released the results of a Preliminary Economic Study (PEA) for Ana Paula showing strong economics at a conservative gold price. This showed a mine with a nine year life producing 101koz/yr after ramp up at an AISC of $1,011/oz. This resulted in upside case economics of an NPV5% of $1,012M, an IRR of 51.3% and average annual after-tax free cash flow of $168M at a $3,800/oz gold price. For more details, see the press release here.

Cerro del Gallo Project

During Q3 2025, the Company conducted advanced study work towards releasing a prefeasibility study for the Cerro del Gallo project based on information collected by previous owners. This work includes updated resources and reserves based on an updated gold price as well as better definition of transition material and an optimized mining and stacking plan. The results of this study are planned to be released in the coming weeks. All major environmental and other permits will need to be obtained before an investment decision can be considered by the Company.

Funding Overview

In the three months ended September 30, 2025, 5,916,250 warrants and 766,250 stock options were exercised for total proceeds of $1.5 million and 1,299,579 RSUs were converted.

As of September 30, 2025, the Company had no debt.

Change of Year End

The Company has changed its financial year-end from March 31 of each year to December 31 of each year. The next financial year-end of the Company will occur on December 31, 2025, for the nine months then ended.

Non-IFRS Measures. This news release refers to certain financial measures, such as all-in-sustaining costs, which are not measures recognized under IFRS and do not have a standardized meaning prescribed by IFRS. These measures may differ from those made by other companies and, accordingly, may not be comparable to such measures as reported by other companies. These measures have been derived from the Company’s financial statements because the Company believes that they are of assistance in understanding the results of operations and its financial position. Certain additional disclosures for these specified financial measures have been incorporated by reference and can be found in the Company’s MD&A for Q3 2025, available on SEDAR+.

Cash costs. The Company uses cash costs per gold equivalent ounce sold to monitor its operating performance internally. The most directly comparable measure prepared in accordance with IFRS is cost of sales. The Company believes this measure provides investors and analysts with useful information about its underlying cash costs of operations. The Company also believes it is a relevant metric used to understand its operating profitability and ability to generate cash flow. Cash costs are measures developed by metals companies in an effort to provide a comparable standard; however, there can be no assurance that the Company’s reporting of these non-GAAP financial measures are similar to those reported by other mining companies. They are widely reported in the metals mining industry as a benchmark for performance, but do not have a standardized meaning and are disclosed in addition to IFRS measures. Cash costs include production costs, refinery and transportation costs and extraordinary mining duty. Cash costs exclude non-cash depreciation and depletion and site share-based compensation. Production costs include mining, crushing, processing, and direct overhead at the operation sites.

AISC. 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. AISC per GEO includes mining, processing, direct overhead, reclamation and sustaining capital.

(TheNewswire)

GRANDE PRAIRIE, ALBERTA TheNewswire – (Nov. 20, 2025): Angkor Resources Corp. (TSXV: ANK,OTC:ANKOF) (‘ANGKOR’ OR ‘THE COMPANY’) announces further analysis, assays, and conclusions on the drill core from Andong Bor license in Oddar Meanchey Cambodia.

Dennis Ouellette, VP Exploration for Angkor, with associate geologists has reviewed the Andong Bor drill core from historical drilling with the most recently 2025 drilled holes 009 and 010.  The two new holes (ABDDH25 -009, -010), of which 009 was substantially deeper, has sections of drill core, roughly from 245 metres to 316 metres in which mineralization with abundant pyrite and chalcopyrite was observed.

Previously, in late 2022, analysis was based only on core drilled by a different company. (see  press release ANGKOR CONFIRMS 108 METRES OF 0.53% COPPER EQUIVALENT AT ANDONG BOR, CAMBODIA | Angkor Resources Corp. )The 2025 drill core from both holes is being logged in detail and cut for sampling purposes.

Further conclusions from the analysis indicate that the structural relationship between the intrusive rock and the host sedimentary rock was not revealed in the previous drilling (ADBDH16-005, -006, -007, -008) as all the contacts were faulted or there was poor core recovery at those sites.

Figure 2 Drill core marked for cutting (see pink lines on core at bottom of picture).

Mr. Ouellette summarizes findings, ‘The best copper mineralization in Andong Bor diamond drill core is hosted by the sedimentary rocks. The diorite (coarse-grained rock) feldspar porphyry intrusive rocks can host low grade copper porphyry-style mineralization, such as ‘B’ and ‘D’ style veins and disseminations. However, in proximity to the highly reactive wallrock (where the intrusive rock is surrounded by the sedimentary rock), the assay values increase dramatically.’

He continues with other conclusions, ‘ The contacts where sedimentary rock and intrusive rock have met are very steep – from 70 to 80 degrees. Mineralization within the sediments is both disseminated and along fractures parallel to these contacts. This implies significant ground preparation (probably with magma or similar catalysts) prior to mineralization.   The sedimentary (country) rock was heavily fractured, so when the intrusion and mineralization events occurred, they followed the pre-existing fractures.  Knowing this impacts the design of our continuation of the drill program in a manner which we expect will result in both shallower and increased mineralized intercepts.’

Assays will be forwarded to ALS when all core cutting is completed and plans for continuation of drilling extend into 2026.

E-Power Resources Inc. (CSE: EPR) (‘E-Power’ or the ‘Company’) is pleased to provide the results of recently completed metallurgical testwork from the Company’s flagship Tetepisca Flake Graphite Property located in the Innu Nation of Pessamit, North Shore Region of Quebec. The metallurgical testwork was completed at SGS Canada Inc. (‘SGS’).

Highlights

• Exceptional Metallurgical Results: Achieved 96.7% Flotation Recovery and a 94.8% Ct Concentrate Grade from the Graphi West sample, confirming amenability to producing a high-purity product.

• Significant Large Flake Recovery: Flake size distribution for the Syndicate concentrate showed approximately 40% medium flake or larger (> 80 mesh), including approximately 22% large flake or larger, a key indicator of high-value product potential.

• High Resource Grade Potential: High grade bulk samples from three distinct mineralized zones have been tested: the Captain Cosmos Target (32.7% Cg), the Syndicate Target (25.0% Cg), and the Graphi West target (15.3% Cg).

Jamie Lavigne, COO for E-Power commented: ‘The metallurgical test work is the first completed on the Company’s Tetepisca property and was designed as a scoping-level evaluation of graphite recovery. The results demonstrate the potential for flake graphite mineralization on the Tetepisca property to yield a high value concentrate with composition and flake size characteristics meeting commercial specifications. These results, and the results of additional test work planned, will provide a basis for prioritizing targets on our large position for delineation and resource estimation.’

Metallurgical Test Results Summary

Samples from the Syndicate, Graphi West, and Captain Cosmos targets were tested. The objective was a scoping-level evaluation of flotation potential with a flow sheet target concentrate grade was 95% Ct. Particle size analyses were completed on the final concentrates.

Both the Graphi West (94.8% Ct) and Syndicate (94.7% Ct) samples achieved concentrate grade very close to the target. The weighted average grade for the four middle particle size classes (<300 µm) to (>44 µm) was (96.41% Ct) for Graphi West and (96.34% Ct) for Syndicate. Further work utilizing a revised flow sheet is planned for the Captain Cosmos target.
