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.’

TORONTO, ONTARIO (January 7, 2026) – TheNewswire – LAURION Mineral Exploration Inc. (TSX-V: LME | OTC: LMEFF | FSE: 5YD) (‘LAURION’ or the ‘Corporation’) is very pleased to report assay results of the first two drill holes from recent diamond drilling at the A-Zone/McLeod/CRK Zone at the Ishkōday Project, located in the Beardmore–Geraldton Greenstone Belt of north-western Ontario, approximately 220 kilometres northeast of Thunder Bay.

The current drill program focuses on the A-Zone/McLeod/CRK Zone, a structurally controlled gold-base metal corridor where historic drilling, surface work, and more recent LAURION drilling demonstrate repeated gold, silver, zinc, and copper mineralization along strike and at depth.

‘These results reinforce what we have been methodically building at Ishkōday — a structurally controlled gold-zinc system with repeated mineralization along a coherent corridor,‘ stated Cynthia Le Sueur Aquin, President and CEO of LAURION. ‘The combination of higher-grade intervals within broader mineralized zones, supported by both historic and recent drilling, gives us confidence that our targeting approach is working as intended. As we continue drilling, our focus remains on understanding continuity, structure, and scale.’

Drill hole LBX25-095 was designed to test a segment of the A-Zone/McLeod/CRK Zone structural corridor supported by proximal historic drill holes 90-41 and 90-49, as well as modern LAURION drill holes LBX20-021 and LBX20-017. Historic drill hole 90-41 intersected multiple gold-bearing intervals at various depths, including 0.55 m grading 3.69 g/t Au and 1.70% Zn, 0.55 m grading 11.88 g/t Au, 8.0 g/t Ag and 8.6% Zn, and deeper intersections including 0.91 m grading 1.63 g/t Au,16.0 g/t Ag, 0.16% Cu and 6.7% Zn, 0.66 m grading 2.12 g/t Au, 14.0 g/t Ag and 10.3% Zn, and 5.36 m grading 0.44 g/t Au, 6.16 g/t Ag and 4.28% Zn (Orient Resources Inc., Sturgeon River Property Diamond Drill Program Report, Claude Larouche, 1990). Nearby historic drill hole 90-49 returned 0.31 m grading 3.87 g/t Au and 1.73 m grading 3.46 g/t Au, 20.36 g/t Ag and 3.72% Zn (Orient Resources Inc., Claude Larouche, 1990). More recent drilling confirmed continuity of mineralization within the same corridor, including 14.08 m grading 0.89 g/t Au in drill hole LBX20-021 and additional gold-silver intervals in LBX20-017 (LAURION press release dated July 28, 2020).

Drill hole LBX25-095 intersected multiple gold-and-zinc-bearing intervals hosted within sheared and altered volcanic rocks consistent with the main A-Zone/McLeod/CRK Zone geological framework.

Reported assay results include 2.60 m grading 1.84 g/t Au from 27.40 to 30.00 m, including 0.60 m grading 7.25 g/t Au, 1.00 m grading 1.02 g/t Au from 45.30 to 46.30 m, and several broader intervals of lower-grade gold with elevated zinc.

A mid-depth mineralized zone returned 3.50 m grading 1.40 g/t Au and 2.30% Zn from 162.50 to 166.00 m, including a higher-grade interval of 0.70 m grading 5.97 g/t Au, 18.4 g/t Ag, 0.22% Cu and 10.8% Zn from 163.05 to 163.75 m.

Deeper in the hole, drilling intersected 4.50 m grading 2.00 g/t Au, 5.75 g/t Ag and 1.22% Zn from 188.00 to 192.50 m, including 0.50 m grading 3.30 g/t Au,17.8 g/t Ag and 6.84% Zn, 2.40 m grading 3.00 g/t Au, and 0.55 m grading 12.15 g/t Au,16.1 g/t Ag and 2.66% Zn.  

Drill hole LBX25-096, located approximately 52 metres east of LBX25-095, was designed to test the eastern continuation of the same structurally controlled mineralized corridor. Targeting for LBX25-096 was informed by proximal drill holes LBX12-006, LBX20-020, and LBX22-089, which intersected gold-bearing mineralization within the same stratigraphic and structural package. Notably, drill hole LBX20-020 returned broad gold-bearing intervals including 6.86 m grading 0.47 g/t Au and 10.84 m grading 0.48 g/t Au, demonstrating mineralized width and continuity and supporting step-out drilling to the east (LAURION press release dated July 28, 2020). Drill hole LBX25-096 subsequently intersected multiple gold-bearing intervals within this corridor, including 3.85 m from 38.70 m to 42.55 m grading 1.92 g/t Au, including a higher-grade interval of 0.55 m from 42.00 m to 42.55 m grading 9.59 g/t Au, and a shallow interval of 1.15 m from 8.35 m to 9.50 m grading 2.14 g/t Au, including 0.50 m from 9.00 m to 9.50 m grading 4.76 g/t Au.

Gold mineralization at Ishkōday occurs within an orogenic gold framework and is commonly accompanied by silver, consistent with orogenic systems globally. In addition, localized enrichment in silver and base metals reflects polymetallic mineralizing events that are overprinted and locally modified by the orogenic gold event. These observations align with structural and geochemical interpretations supporting a multi-phase mineralizing history, as outlined in the Keaton Strongman Report 2024 on the Ishkōday: Ancestral structural controls between Archean epithermal and orogenic gold mineralization.

TABLE Of ASSAYS FOR DRILL HOLES LBX25-095 AND LBX25-096

Mineralization on the A-Zone/McLeod/CRK Zone is interpreted to be controlled by the interaction of north–south-trending quartz-gold extensional veins and northeast–southwest-trending sulphide-rich shear veins. Reactivation of earlier sulphide zones during later deformation, locally associated with magnetite-rich assemblages, provides a structural framework that explains repeated gold enrichment, localized grade enhancement within wider base metal envelopes, and strong strike continuity beneath cover.

The current drilling on the A-Zone/McLeod/CRK Zone has focused on refining LAURION’s understanding of the geometry, continuity, and structural controls of the mineralized system. Ongoing work by the LAURION’s technical team and independent consultants is centred on consolidating historical and modern drilling, validating geological interpretations, and strengthening the 3D structural framework. This work is intended to ensure that any future technical milestones are based on a robust, well-constrained geological model, while preserving strategic flexibility as the Ishkōday Project continues to evolve.

Sampling and QA/QC Protocols

All drill core is transported and stored inside the core facility located at the Ishkōday Project in Greenstone, Ontario. LAURION employs an industry standard system of external standards, blanks and duplicates for all of its sampling, in addition to the QA/QC protocol employed by the laboratory. After logging, core samples were identified and then cut in half along core axis in the same building and then zip tied individually in plastic sample bags with a bar code. Approximately five or six of these individual bags were then stacked into a ‘rice’ white material bag and stored on a skid for final shipment to the laboratory.

All core samples were shipped to the ALS facility in Thunder Bay, Ontario, which were then prepared by ALS Global Geochemistry in Thunder Bay and analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (Inductively Coupled Plasma – Atomic Emission Spectroscopy). Over limit analyses are reprocessed with gravimetric finish.

A total of 5% blanks and 5% standard are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. All QA/QC were verified, and no contamination or bias have been observed. The remaining half of the core, as well as the unsampled core, is stored in temporary core racks at the core logging facility in Beardmore and moved to the core storage facility at the Ishkōday Project.

Note: QA/QC review of standards and duplicates indicates analytical results are reliable. One zinc standard adjacent to a high-grade zinc interval returned elevated values consistent with expected analytical behaviour following high-grade samples.

Crown Porphyry-Stockwork Drill Targets Confirmed

Vancouver, British Columbia, January 7th, 2026 TheNewswire Prismo Metals Inc. (‘Prismo’ or the ‘Company’) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce it has received final assay results for samples taken at the Silver King Project from the Crown porphyry target area located on the east side of the property (Fig. 1).

Overlimit silver assays have been received for the samples taken in late 2025, showing high grade silver mineralization associated with quartz-sulfide veins hosted by the Crown porphyry (Fig 2, Table 1). These assays provide evidence for a high-priority drill target, especially when taken in conjunction with the high gold assays reported previously for the stockwork intrusion (see the News Release of Dec. 3, 2025).  

‘Prismo optioned Silver King with existing drill targets around the historically significant high-grade silver mine. Based on the geology and its location in a well mineralized region, we believed that additional mineralization was also likely present. Our work in the second half of 2025 indicates that we were correct, and we now have exceptional drill targets at the Crown porphyry and adjacent Black Diamond replacement areas,’ stated Craig Gibson, Chief Exploration Officer of the Company. He added, ‘With the high-grade gold assays reported in December and the copper assays at the Black Diamond replacement, we now have a very significant precious-metal and copper target at Silver King similar to other areas in this well mineralized district that includes the Magma mine and the Resolution copper deposit.’  

‘These additional assay results along with the IP survey information continue to enhance and support our exploration thesis of the Silver King mine and surrounding areas,’ stated Gordon Aldcorn.  ‘This modern-day review has yielded additional drill targets and prospective structures to our program in this already very strategically located project.’

IP Survey

The Company also completed a pole-dipole IP survey over a part of the Silver King project in December 2025.  This survey was designed to provide some additional 3-dimensional data for areas identified during the initial gradient array survey (see News Release dated December 3, 2025). This new survey confirmed the presence of important chargeability and resistivity anomalies at the Silver King project. The Silver King silver mine appears to be associated with a large low resistivity anomaly located on the contact of the Silver King diorite porphyry (Fig 3). There is also low resistivity anomalies associated with the Crown porphyry and near the replacement mineralization at Black Diamond (Fig 3). The highest chargeability anomalies appear to be associated with the altered country rocks along intrusive contacts, but a chargeability high is also associated with the Crown porphyry stockwork intrusion. The anomaly associated with the Crown porphyry is particularly interesting and can be traced from shallow levels to about 300 meters in depth.

Drilling Update

Alain Lambert, CEO of Prismo commented: ‘The results announced today confirm the vast exploration potential at Silver King. While we look forward to drilling these new targets in the future, our plans remain unchanged. Our immediate priority is to undertake our fully funded drill program, as previously announced. This drill campaign will primarily focus on the historic Silver King mine site and will be about 2,000 meters. The objective is to test the upper half of the steeply dipping pipelike Silver King mineralized body as well as potential mineralization adjacent to the dense stockwork that was the focus of historic mining.’

Mr. Lambert added: ‘We are pleased with the steady progress on the permitting front. The collaboration of Forest Service officials demonstrates a clear commitment to supporting mining activities in Arizona.’

Prismo recently announced that the Forest Service, the federal surface land management entity for Silver King, had determined that the Company’s proposed drill plan meets the regulatory requirements for processing, and that such plan is complete, as described in the regulations at 36 CFR 228.4(c).

The Forest Service is currently proceeding with the environmental analysis pursuant to 36 CFR 228(a)(5) in conformity with the National Environmental Policy Act (NEPA). This analysis is proceeding as a Categorical Exclusion, the lowest level of environment reviews applicable to projects that are not expected to have a significant effect on the environment, such as Silver King.

QA/QC

Samples were analyzed by SGS, an internationally recognized analytical lab, with preparation at the Tempe, Arizona facility and analyses at the Burnaby laboratory.  Prismo inserts controls samples consisting of a standard pulps and a coarse blanks in the sample stream, and the lab also inserts control samples.
