Nevada Sunrise Metals Corporation (TSXV: NEV,OTC:NVSGF) (OTC Pink: NVSGF) (‘Nevada Sunrise’ or the ‘Company’) is pleased to announce it has completed surface geophysical and geochemical exploration surveys at its Griffon Gold Mine Project (‘Griffon’, or the ‘Project’) in White Pine County, Nevada, USA. Griffon hosts a past-producing gold mine and is located within the Battle Mountain-Eureka Gold Belt, a prolific trend that contains numerous gold mines and deposits.

Highlights of the Fall 2025 Exploration Program

Nevada Sunrise based its Fall 2025 surface exploration program on the results of AI-generated analysis by VRIFY Technology Inc. (‘VRIFY‘) of the extensive historical Griffon geological and geophysical database for the Project (see Nevada Sunrise news release dated September 9, 2025), including:

• Over 700 soil samples collected by APEX Geoscience USA (‘APEX’) will be analyzed by partial leach geochemical analysis by both Ionic Leach and Soil Gas Hydrocarbon (‘SGH’) methods. Each of these methods are capable of detecting subtle indications of buried mineralization that may not show robust surface expression from conventional soil surveys;

• APEX carried out a ‘walking mag’ survey consisting of 50-line kilometres that has provided the first ever high-resolution magnetic data at Griffon. Preliminary interpretation of the data has revealed important information about the structural settings of the past-producing Discovery Ridge and Hammer Ridge deposits – knowledge which now can be applied to other untested target areas at the Project;

• SJ Geophysics Ltd. carried out 3D induced polarization/resistivity (‘3D-IP’) and audiomagnetotellurics (‘AMT’) surveys consisting of 16.8 line kilometres on grids designed to investigate the resistivity and chargeability characteristics of the subsurface at Griffon. These survey types have never been performed at Griffon since the discovery of gold on the property in 1986 (see Figure 1).

Nevada Sunrise anticipates the receipt of geochemical analyses and geophysical modeling from the ground surveys in January 2026. Re-sampling and multi-element geochemical analysis of reverse circulation drill cuttings collected at Griffon by Fremont Gold Ltd. (now Hayasa Metals Inc.) in 2020, which were historically assayed only for gold, is still in progress. The broader analytical package will include pathfinder elements such as antimony, arsenic, thallium, and mercury that could provide geochemical vectors to enhance drill targeting at the Project.

Griffon Permitting Update

In late September 2025, Nevada Sunrise submitted a Plan of Operations (the ‘Plan‘) for Griffon to the United States Forest Service (the ‘USFS‘) to advise the USFS of the Company’s proposed surface disturbance and 2026 drilling plans at Griffon. Receipt of the Plan was confirmed in October 2025 and the Company awaits comments from the USFS regarding the timing and recommended execution of environmental baseline surveys that are a requisite before the commencement of drilling.

About Griffon

Griffon is located approximately 50 kilometres (33 miles) southwest of Ely, Nevada and consists of 89 unpatented mineral claims totaling approximately 1,780 acres (720 hectares). Griffon is situated within a 60 kilometre (40 mile) section of the Battle Mountain-Eureka Belt, which hosts operating gold mines and significant gold deposits (see Figure 2).

In February 2025, the Company entered into a mining lease to purchase Griffon from an arm’s-length party (see Nevada Sunrise news release dated February 20, 2025). Gold was mined at Griffon in two open pits from 1998 to 1999 and was reported to have produced 62,661 ounces of oxide gold until its premature closure in 1999, a year when the price of gold averaged approximately US$278 per ounce.¹

About Standard Uranium (TSXV: STND,OTC:STTDF)

We find the fuel to power a clean energy future

Standard Uranium is a uranium exploration company and emerging project generator poised for discovery in the world’s richest uranium district. The Company holds interest in over 235,435 acres (95,277 hectares) in the world-class Athabasca Basin in Saskatchewan, Canada.

Standard Uranium’s Davidson River Project, in the southwest part of the Athabasca Basin, Saskatchewan, comprises ten mineral claims over 30,737 hectares. Davidson River is highly prospective for basement-hosted uranium deposits due to its location along trend from recent high-grade uranium discoveries. However, owing to the large project size with multiple targets, it remains broadly under-tested by drilling. Recent intersections of wide, structurally deformed and strongly altered shear zones provide significant confidence in the exploration model and future success is expected.

Standard Uranium’s eastern Athabasca projects comprise over 43,185 hectares of prospective land holdings. The eastern basin projects are highly prospective for unconformity related and/or basement hosted uranium deposits based on historical uranium occurrences, recently identified geophysical anomalies, and location along trend from several high-grade uranium discoveries.

Standard Uranium’s Sun Dog project, in the northwest part of the Athabasca Basin, Saskatchewan, is comprised of nine mineral claims over 19,603 hectares. The Sun Dog project is highly prospective for basement and unconformity hosted uranium deposits yet remains largely untested by sufficient drilling despite its location proximal to uranium discoveries in the area.

(TheNewswire)

Vancouver, Canada, December 18, 2025 TheNewswire – Spartan Metals Corp. (‘Spartan’ or the ‘Company’) (TSX-V: W | OTCQB: SPRMF | FSE: J03) is pleased to announce assay results from the drilling program at the Tungstonia Tailings deposit, which is part of the company’s 100% owned Eagle Tungsten-Silver-Rubidium Project (‘Eagle’ or ‘Project’) in eastern Nevada. The program consisted of 34 ~6.4-centimeter (2.5 inch) holes at approximate 12 meter (m) spacing totaling ~67 (m) comprising 133 samples with an average depth of near 2 m aligned with pre-drilling estimates of the tailings thickness.

Highlights:

• Grades consistent with 2024 surface samples with weighted averages (based on sample weights) as follows: 

  • Tungsten grades of 0.13% WO 

  • Silver grades of 10.6 g/t 

  • Rubidium grades of 626 ppm 

• Relatively consistent grades encountered in all holes with notable highlights: 

* – holes were drilled in feet and converted to meters, intervals may not sum due to rounding.

** – tungsten was assayed as W ppm, converted W%, and then to WO3% using 1.261 conversion factor

Brett Marsh, Spartan’s President and CEO, states, ‘These positive assay results support our belief that the legacy Tungstonia tailings can be an important part of Spartan’s current objectives and could potentially contribute to the US tungsten and rubidium supply chain. We anticipate receiving metallurgical results from this program within the next couple of months that will help us better understand the economic potential we have in our readily accessible tailings and waste rock.’

Rebecca Ball, Spartan’s Vice President of Exploration, states, ‘Coming from a military family, I believe it is crucial to have a strong domestic critical metal supply chain. These tungsten and rubidium results may provide a new nationally significant presence of critical defense metals and potentially bring us closer to helping the US onshore it’s critical metal sources and decrease our reliance on foreign imports. I respect our military service members, and I am proud to be able to potentially help provide the US with resources that contribute to the security of those who serve and protect the USA.’

34 holes (Figures 1 to 3) were advanced vertically into the legacy tailings using a truck mounted auto hammer equipped hollow stem auger rig – the auger was not required because the coarse sand sized tail material is well compacted and the auto hammer advanced well and returned high quality samples. Each hole was advanced through the entirety of the tailings until native ground was encountered. Recovery was excellent at near 100% for all collected samples, representative images are shown in Figures 4 to 6. Samples were collected at 0.46 m (1.5 ft) and 0.61 m (2 ft) intervals from surface using 6.4-centimeter (2.5-inch) California split spoon tube sampler equipped with sand catcher. The full sample was placed into 11’x17′ Nano-Por Geological sample bags, sealed, and delivered to American Assay Lab (AAL) in Reno, Nevada for assay with representative material saved in chip trays for preservation. Field duplicates were obtained by splitting the sample into two equal portions and following the same procedures as full samples.

Sample intervals are considered true thicknesses as the tails were deposited horizontally and internal layering observed in the samples was effectively perpendicular to the vertical sample direction.

Significance of Assay Results

The weighted average tungsten results of 0.13% WO3 from all 133 samples is near cutoff for currently operating mines with the Almonty, Sangdong mine cutoff in South Korea reported at 0.15% WO3 (1). If the 0.15% WO3 cutoff from Sangdong – an underground mine – is applied, the weighted average of the 41 resulting samples is 0.20% WO3. The potential addition of silver and rubidium credits makes these results very encouraging and since the tailings have already been mined, transported, and processed, it is likely that a potential economic cutoff could be closer to the average of 0.13% WO3 obtained from the weighted average of all samples in this program.

Next Steps

Spartan will continue execution of the entire Phase 1 of the recommended work program from Spartan’s July 31, 2025, NI 43-101 Technical Report which is the characterization of the Tungstonia tailings that will be focused on metallurgical analysis, definition the overall geometry for tonnage calculations, 3D modeling, quantitative assessment, resource estimation, and economic evaluation to definitively determine economic viability and associated cutoff grades and there is no guarantee of economic viability.

Two holes drilled as twins of Tails-2519 and Tails-2527 were sampled in their entirety and delivered to McClelland Labs, Reno, Nevada for geological and metallurgical testing. The analyses are intended to identify the minerals that host tungsten and rubidium and understand recoverability using gravity and various leaching scenarios and will include:

• QEMSCAN mineralogical identification, 

• Whole rock geochemical analysis, 

• Acid leach tests (Rb and W), 

• Sulfide flotation tests (Ag potentially in galena), 

• Mica flotation for Rb, 

• Detailed gravity concentration testing. 

Spartan is currently developing the geometry and 3D models to be used as input for the initial resource estimate and economic evaluation with anticipated completion in early 2026.

QA/QC Procedures

Samples were submitted to American Assay Lab (AAL) of Sparks, Nevada, which is a certified and accredited laboratory, independent of the Company. Samples are prepared using industry standard-prep methods and analyzed using method IM-4AB61 (61 element suite: 0.5g 4-acid plus boric acid hot block, ICP-OES+MS) plus IM-4ABEx ICP-MS for over limit Rb and G-FAAuAg – 30g gravimetric fire assay for overlimit Ag. AAL undertakes its own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. Spartan’s QAQC includes regular insertion of CRM standards, duplicates, and blanks with a stringent review of results completed by the Company’s Qualified Person, Brett R. Marsh, President and CEO of Spartan Metals.

About The Eagle Project

The Eagle Project presents a unique opportunity to delineate one of the largest and highest-grade Tungsten (‘W’) and Rubidium (‘Rb’) districts in the United States. The Project consists of the past-producing high-grade Tungstonia and Rees/Antelope tungsten (W-Cu-Ag) mines. Operations at these mines were from 1915 to 1942 with intermittent small-scale production occurring until 1956. Tungsten production from these two mines totaled 8,379 units at grades between 0.6%-0.9% WO3 (2).

The Project is ~36.5 km² in size and located approximately 120 kilometers northeast of the town of Ely, in the Kern Mountains of White Pine County, Nevada. The Project covers 9,033 acres consisting of 445 Bureau of Land Management (BLM) unpatented lode mining claims. 

Three deposit types are present at Eagle; Porphyry, Skarn, and Carbonate Replacement (CRD) that contain significant or anomalous grades of Tungsten (W), Silver (Ag), and Rubidium (Rb) plus Cu-Sb±Au-Pb-Zn-Bi-As across three project focus areas that also includes the potential to recover W-Rb-Ag from the legacy Tungstonia Mill Tailings.

HIGHLIGHTS:

• Restart of mining operations at San Agustin

• Mining the reserve will produce 45,000 ounces at an AISC of $1,990/GEO providing a margin of over $2,300/oz at current spot gold prices

• Oxide targets drilling program underway with 37 holes completed and submitted for analysis

Heliostar Metals Ltd. (TSXV: HSTR,OTC:HSTXF) (OTCQX: HSTXF) (FSE: RGG1) (‘Heliostar’ or the ‘Company’) is pleased to announce that mining, crushing and conveying and stacking of ore onto the leach pad at San Agustin has recommenced.

Heliostar CEO, Charles Funk, commented, ‘Restarting mining at San Agustin is a significant milestone for Heliostar. It delivers on our guidance of a Q4, 2025 restart issued at the beginning of the year and sets the Company up for a large increase in consolidated gold production in 2026. Mining the current reserve will produce 45,000 ounces of gold expected to generate US$40M in cash flow at a US$3,000 gold price. Further, the Company is in the middle of a 10,000-15,000 metre drill program focused on finding potential extensions of the orebody that may support an increase in mine life at San Agustin.’

‘Investing in Heliostar at the beginning of the year required trust that the many undefined opportunities recognized by our team within our portfolio could be progressed. We move toward the end of the year having crystalized many of these opportunities. We have certainty in our production profile at San Agustin and La Colorada going into 2026 and look forward to providing formal guidance in January. We have shown the value of our growth opportunities with studies on our flagship Ana Paula and Cerro del Gallo projects. With more drilling completed in 2025 than the entire previous history of Heliostar, we aim to continue to build on our 8.2M gold and gold-equivalent ounce M&I resource base^1,2. We plan to deliver continued production growth, and grow the value of Heliostar on a per share basis. We are only just getting started!’

Restart Update

The Company announced it had received the final approvals from the government to restart mining at San Agustin on July 22, 2025. Since that time, Heliostar has rapidly advanced work to restart mining activities at the operation. This included purchase and transfer of the surface access rights to Heliostar, adjusting the location of a power line tower and establishing surface access roads to the Corner area.

Over the past several months, the Company has relocated the vegetation and topsoil at the Corner area and recommissioned the 30,000 tonne per day crushing circuit while residual heap leach operations have continued uninterrupted. This has allowed Heliostar to restart open pit mining with two ore blasts and two waste blasts completed to date. The mining contractor has successfully mobilized 90% of the mobile equipment fleet to site which will allow the operation to achieve production targets. Crushing activities continue to ramp up to full capacity with stacking of new oxide ore on the leach pad underway.

Technical Report Summary

On January 14, 2025, the Company filed an amended and restated technical report titled ‘San Agustin Operations, Durango State, Mexico, NI 43-101 Technical Report’ prepared by Mr. Todd Wakefield, RM SME, Mine Technical Services, Mr. David Thomas, P.Geo., Mine Technical Services, Mr. Jeffrey Choquette, P.E., Hard Rock Consulting, Mr. Carl Defilippi, RM SME, Kappes Cassiday and Associates and Ms. Dawn Garcia, CPG, Stantec with an effective date of November 30, 2024 (the ‘Technical Report’).

The life-of-mine (LOM) plan set out in the Technical Report indicates that a probable mineral reserve of 68,000 ounces of gold can be exploited based on 1.2 years of mine life at a site level all-in sustaining cost (AISC) of US$1,990/oz Au. The initial capital cost in the Technical Report is estimated at US$4.2M.

The Technical Report demonstrates a post-tax NPV5% of US$35.3M, a post-tax IRR of 548% and a payback period of 0.2 years for the upside case at a $3,000/oz gold price.

The mineral reserve estimate included in the Technical Report is based on operation of the existing crusher and conveyor system having a nameplate throughput capacity of about 30,000 tonnes/day and the continued operation of the heap leach and carbon-in-column (CIC) process circuit processing ore from the expanded open pit. The mineral reserve estimate included in the Technical Report is presented below. The expected operating performance and operating cost forecasts were compiled with the benefit of benchmarking historical performance at San Agustin and the input of seasoned professionals knowledgeable of the conventional technologies being used at San Agustin, the expected consumption quantities of key supplies, and commercial pricing for goods and services in Mexico.

Oxide Growth Targets

With mining now started at San Agustin mine, the Company is working to extend the mine life. To date, 37 drill holes totalling 3,300m from the ongoing 10,000-15,000m drill program have been completed with assays pending. This drill program is focused on defining additional gold-bearing oxide gold material at the margins of the current pit and at the edge of the Corner Area that can extend the life of the operation. Drilling at the Corner SW, MKT and Phase 3 SW areas (shown below in Figure 6) has been completed with the drill currently active at the Corner SW area.

Higher-grade oxide results from the priority Corner SW target area drilled by a previous operator include:

• Hole 14-SAGRC-196 grading 3.52 grams per tonne (g/t) Gold over 18.3 metres from 32.0 metres downhole

• Hole 14-SAGRC-177 grading 0.34 g/t Gold over 15.24 metres from 27.4 metres downhole

The targets are the extensions of mineralized corridors defined by grade control drilling and through a comprehensive re-logging and multi-element re-assaying program undertaken by Heliostar geologists in H1, 2025. The increase in gold price has also increased the potential of certain lower grade areas that were not previously a priority at San Agustin. The base case economics in the January 2025 Technical Report were shown at a $2,100/oz gold price within resource pit shells calculated at $2,150/oz.
