Nevgold Corp. (‘ NevGold ‘ or the ‘ Company ‘) ( TSXV:NAU,OTC:NAUFF) (OTCQX:NAUFF) (Frankfurt:5E50 ) is pleased to announce an updated Mineral Resource Estimate (‘ MRE ‘) for the Nutmeg Mountain gold project (the ‘ Project ‘, ‘ Nutmeg Mountain ‘) in Idaho.

Key Highlights

• Open-Pit, Oxide, Heap-Leach Gold Mineral Resource in the Western USA: 1.19 Mozs of Indicated Resources at 0.50 g/t Au (74.2 Mt) and 548 kozs of Inferred Resources at 0.34 g/t Au (49.8 Mt). (Table 1, Figure 1, Figure 2)

• Higher Grade Mineralization Within the Resource: increasing the cut-off grade from the base case of 0.20 g/t Au to 0.60 g/t Au, the Project has 560 kozs of Indicated Resources at 0.92 g/t Au , and 85 kozs of Inferred Resources at 0.87 g/t Au . The higher grade mineralization starts at surface as seen in Figure 2 and Figure 3, and is within the 0.20 g/t Au cut-off grade MRE. To date, the Company has not completed any mine scheduling studies on the MRE. Exploring for more potential high-grade mineralization will be a key focus as the project is advanced with further drilling and subsequent resource estimates.

• Significant Growth Captured Over Last 24 Months: compared to the 2023 MRE, the base case pit-constrained indicated tonnage increased by over 18% and inferred by over 100%, with further upside identified with high priority drill targets.

• Mineralization Starts at Surface with Low Strip Ratio: mineralization at Nutmeg Mountain starts at surface. The strip ratio of the project based on conceptual pit-shells is expected to be less than 1:1 , which is extremely low for an open-pit, oxide, heap-leach gold project. (Figure 2, Figure 3)

• Tier One Jurisdiction: the Project is located in southwest Idaho, which is a favorable mining jurisdiction. (Figure 4, Figure 5)

NevGold CEO, Brandon Bonifacio, comments: ‘This is another important milestone for NevGold and the Nutmeg Mountain gold project in Idaho as it further validates the quality of the asset located in a tier-one mining jurisdiction. We are pleased with the results of the updated MRE, as it illustrates the size and heap-leach grade of this at-surface, open-pit oxide gold project in the Western USA. The updated MRE also further validates the strong growth potential of mineralization at the Project, which remains open in multiple directions. We look forward to drilling the highly prospective targets that we have identified at surface and at depth. After completion of this MRE, we plan to advance to a Preliminary Economic Assessment (PEA) to further advance the Project to the next stage of development. We have an extremely favorable macroeconomic situation with the gold price and momentum in the US to advance high-quality, domestic mineral projects . ‘

Notes:

1. Effective date of this mineral resource estimate is August 29, 2025.
2. All mineral resources have been estimated in accordance with Canadian Institute of Mining, Metallurgy and Petroleum definitions, as required under National Instrument 43-101 (‘ NI 43-101 ‘). The Mineral Resource Statement was prepared by Greg Mosher, P. Geo (Global Mineral Resource Services, ‘ GMRS ‘) in accordance with NI 43-101.
3. Mineral Resources reported demonstrate a reasonable prospect of eventual economic extraction through additional exploration, as required under NI 43-101. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the estimated Mineral Resources will be converted into Mineral Reserves. The potential development of the Mineral Resources may be materially affected by environmental, permitting, legal, marketing, and other relevant issues.
4. Mineral Resources are reported at a cut-off grade of 0.20 g/t Au for an open-pit mining scenario. Cut-off grades are based on a price of US$2350/oz gold, and a number of operating cost and recovery assumptions, including a reasonable contingency factor. Metallurgical recoveries of 80% were used. Densities based on lithology were assigned.
5. Ounce (troy) = metric tonnes x grade / 31.10348. All numbers have been rounded to reflect the relative accuracy of the estimate.
6. The quantity and grade of reported Inferred Mineral Resources are uncertain in nature and there has not been sufficient work to define these Inferred Mineral Resources as Indicated or Measured Mineral Resources. It is reasonably expected that many of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration, however, there is no assurance that further exploration will result in all or any part of the Inferred Mineral Resources being converted into Indicated Mineral Resources.
7. Tonnages and ounces in the tables are rounded to the nearest thousand and hundred, respectively. Numbers may not total due to rounding.

Nutmeg Mountain – Summary
Nutmeg Mountain is a low-sulphidation epithermal gold deposit located in southwest Idaho, approximately 20 kilometers east of Weiser, Idaho, and 120 kilometers northwest of Boise, Idaho. The Project is approximately 1,724 hectares in size, which is comprised of 210 federal unpatented claims, 12 patented claims, and 2 private leases. The Project has 940 core, reverse circulation (‘RC’), and rotary drill holes totaling over 71,625 meters of drilling.

Nutmeg Mountain – Additional Exploration Potential
The work completed to date by the Company has identified several high priority drill targets for future drilling. Historical drilling was mainly focused on the outcropping and near-surface disseminated mineralization, which is primarily located on the patented mining claims and other privately owned ground. (Figure 1) NevGold has identified numerous additional near-surface gold targets on the unpatented mining claims surrounding the private ground. Additionally, the average drill hole depth at the Project is less than 75 meters, and to date the potential high-grade feeder veins typically associated with low-sulphidation epithermal gold systems have yet to be identified. Discovering additional near-surface disseminated gold mineralization and the potential high-grade feeder structures will continue to be the focus of NevGold’s ongoing exploration.

Nutmeg Mountain Deposit Geology and Model
Nutmeg Mountain is a low-sulphidation epithermal gold deposit with exploration dating back to the 1980s. The Project is host to Miocene-age basalt and tuffaceous sediments, Payette Formation sandstone and siltstone, and lacustrine sedimentary rocks of the Pliocene-age Idaho Group.

Most gold mineralization that has been identified at the Project to date occurs within a north-trending graben, which is where most of the drilling has been concentrated. The graben is bounded by faults on the east and west, and sedimentary units change in thickness and character across the bounding faults. Mineralization is associated with multi-phase hydrothermal brecciation and veining, strong silicification, acid alteration, and faulting. Much of the surface alteration is composed primarily of opaline silica and appears to be replacement of Payette Formation sandstone.

There are four principal zones of mineralization. The Main Zone is the most significant in size and contains most of the gold in the MRE. Gold mineralization is hosted primarily in silicified Payette Formation sandstone that has been subjected to multiple phases of hydrothermal alteration, brecciation, and veining.  The Main Zone mineralization occurs over a north-south distance of approximately 1,200 meters, a width from 250 to 500 meters, and a vertical thickness of up to 180 meters. Most of the gold in the MRE is situated in the top 75 meters of this vertical thickness, creating an opportunity to expand the resource vertically with further deeper drilling and additional data.

The North Zone underlies the narrow ridge crest at the north end of the Project, approximately 600 meters northeast of the Main Zone. In the North Zone, gold mineralization occurs as an oval, north-trending, tabular body that is up to 60 meters thick, approximately 335 meters long (N-S) and 150 meters wide. The Stinking Water Zone lies approximately 400 meters west of the North Zone and 600 meters north of the Main Zone. The Cove Creek Zone is located 600 meters southeast of, and approximately 170 meters lower than the Main Zone, with little to no surface expression.

Drillhole Data and QAQC Procedures
Prior to the Company’s work, the Project was evaluated by several historical work programs starting in the 1980s including geological mapping, geochemical and geophysical surveying, several metallurgical bulk samples and 934 core, RC, and rotary drill holes totaling 70,254 meters. In early 2023, NevGold completed five core holes totaling 1,371 meters, four of which were located within the known envelope of mineralization. The data from these holes have been used in the MRE.

There is minimal documented QA/QC procedures or data available for drill programs prior to 2008. The Company drill program utilized full industry-standard survey control and QAQC programs and is designed to systematically validate as much of the historical drilling as possible through collar surveys, re-logging, and re-sampling.

Reasonable Prospects of Eventual Economic Extraction
To support reasonable prospects for eventual economic extraction for the MRE, GMRS used the estimated block model to generate an optimized pit-shell using the following assumptions: a gold price of US$2350/oz, mining costs of US$2.20/tonne moved, processing costs including general and administration costs of US$5.50/tonne, heap-leach process recovery of 80%, and an overall pit slope angle of 50 degrees. Mining and processing costs are based on industry norms and benchmarking for this type of deposit and contemplated mining method.

Environmental, Social, and Governance Opportunities
As part of its commitment to environmental, social, and governance (ESG) practices, the Company has commenced a review of alternate energy potential near the Project. These alternate sources include geothermal, solar, and wind power generation. In particular, the Project is in an area of high geothermal energy potential with two geothermal projects already operating nearby. There are also a number of solar and wind power generation projects in Idaho. The Company is actively considering collaboration agreements with alternate energy partners to assess opportunities to lower the carbon footprint at the Project.

Sun Summit Minerals Corp. (TSXV: SMN,OTC:SMREF) (OTCQB: SMREF) (‘Sun Summit’ or the ‘Company’) is pleased to report results from a recently completed induced polarization (IP) survey across the JD Porphyry Trend at the JD Project, Toodoggone Mining District, north-central British Columbia.

Highlights:

• New IP data enhances the JD Porphyry Trend: New chargeability and resistivity data demonstrate strong prospectivity for porphyry-related copper-gold mineralization along the JD Porphyry trend.

• Follow-up programs ongoing: Geological mapping and prospecting surveys along the McClair Creek alteration zone are ongoing. Data from recently completed soil surveys along parts of the JD Porphyry trend are being compiled and interpreted to refine drill targets.

• Phase II IP Survey: a subsequent phase of closely-spaced IP survey south of the Creek Zone is newly completed and results are being integrated with the 2024 IP survey historical data and with the current 3D model of the Creek zone.

‘We have now defined a broad 8.5 km long chargeability-high anomaly at JD, significantly enhancing the project’s copper-gold porphyry potential along the McClair Creek alteration zone,’ said Niel Marotta, CEO of Sun Summit Minerals. ‘This impressive alteration zone transects the JD Porphyry trend, yet remarkably, only five historic drill holes have tested it. The vast majority of this large-scale anomaly remains untested and represents a high-priority area for further target definition and exploration.’

The JD Porphyry Trend IP Survey

The IP survey across the JD Porphyry trend consisted of over 31-line kilometers across eight northeast-southwest oriented lines. Line spacing varied from 500 to 1,200 meters depending on design depth of earlier survey arrays (Figure 1). The 2025 survey was designed to characterise and detect subsurface sulfide mineralization associated with pronounced magnetic anomalies and strong hydrothermal alteration observed along McClair creek (see February 5^th, 2025, news release). The IP survey expanded on previous surveys that defined a north-south trending, open ended, high-chargeability anomaly. New and historic data was compiled and inverted (Figures 1 and 2).

The broadly, north-south oriented >18 mv/v McClair Creek chargeability-high anomaly spans 8.5 by ~2 kilometers and is open to the north and south (Figure 2). The broad anomaly is locally spatially coincident with discrete strong magnetic-high anomalies (Figure 2) and near the Belle South target, a strong resistivity-high anomaly. The intensity of the chargeability anomaly increases with depth, particularly to the north where the anomaly increases to +40 mv/v near the Fericrete and Oxide Peak targets (Figure 1).

Besides five widely-spaced drill holes near the McClair target in 2013 and 2018 (Figure 1), no other chargeability anomaly along the 8.5 km trend has been drill tested. Results from the five McClair holes (see February 5^th, 2025 news release) suggests the entire trend may also be prospective for porphyry-related mineralization.

The McClair Creek anomaly is along trend, 17 km north of Amarc Resources’ Aurora discovery (Figure 3). Porphyry-related copper and gold mineralization at Aurora is spatially associated with strong coincident chargeability-high and resistivity-high anomalies centered on a magnetic-high anomaly¹.

Next Steps

This new chargeability and resistivity data supports the strong prospectivity for partially concealed, porphyry-related copper-gold mineralization proximal to the McClair Creek alteration zone (Figure 1). Additional IP surveying is warranted to infill widely spaced lines and to extend the survey footprint to the north and south (Figure 3).

Data from recently completed soil surveys along parts of the JD Porphyry trend are being compiled and interpreted to refine drill targets. Data from these surveys together with results from ongoing geological mapping and prospecting along the McClair Creek alteration zone (Figure 1) will be used to inform drill targeting and testing.

Osisko Metals Incorporated (the ‘ Company ‘ or ‘ Osisko Metals ‘) ( TSX: OM,OTC:OMZNF ; OTCQX: OMZNF ; FRANKFURT: 0B51 ) is pleased to announce new drill results from the Gaspé Copper Project, located in the Gaspé Peninsula of Eastern Québec.

Osisko Metals CEO Robert Wares commented: ‘The growth potential of the Gaspé Copper deposit continues to be demonstrated with today’s new high-grade results. Holes 30-1106 and 30-1109 reveal the presence of a thick, higher grade tabular zone lying at depth around the E Zone horizon near the eastern margin of our 2024 MRE model. This tabular zone may extend significantly to the east if it correlates to historical drilling results. Our expansion drilling is exceeding expectations, hand-in-hand with the solid infill results on our main resource area.’

New analytical results are presented below (see Table 1), including 26 mineralized intercepts from six new drill holes. Infill intercepts are located inside the 2024 MRE model ( see November 14, 2024 news release ), and are focused on upgrading inferred mineral resources to measured or indicated categories, as applicable. Expansion intercepts are located outside the 2024 MRE model and may potentially lead to additional resources that will be classified appropriately within the next MRE update. Some of the reported intercepts have contiguous shallower infill as well as deeper expansion (noted on Table 1 below as ‘Both’). Maps showing hole locations are available at www.osiskometals.com .

Highlights:

• Drill hole 30-1110
  • 1091.5 metres averaging 0.20% Cu (infill and expansion)
• Drill hole 30-1109
  • 133.7 metres averaging 1.04% Cu (expansion)
• Drill hole 30-1106
  • 159.1 metres averaging 0.45% Cu (expansion)
• Drill hole 30-1103
  • 167.9 metres averaging 0.24% Cu (infill)
• Drill hole 30-1108
  • 134.8 metres averaging 0.22% Cu (infill and expansion)
• Drill hole 30-1111
  • 304.5 metres averaging 0.17% Cu (infill)
  • 206.3 metres averaging 0.33% Cu (expansion)

Table 1: Infill and Expansion Drilling Results

* See explanatory notes below on copper equivalent values and Quality Assurance/Quality Controls.
** ‘Both’ indicates drill holes that have contiguous shallower infill as well as deeper expansion intercepts.

Discussion

Drill holes 30-1103 and 30-1108, both located near the western margin of the 2024 MRE model, cut multiple intersections of mineralized material, 20 to 168 metres thick, distributed in ‘layer cake’ fashion from surface to a vertical depth of 854 and 900 metres, respectively.

Drill hole 30-1106, located near the eastern margin of the 2024 MRE model, cut unmineralized material to a depth of about 600 metres, followed by four mineralized intervals to a vertical depth of 1004 metres. These include a higher-grade interval of 33.8 metres averaging 1.04% Cu and 3.60 g/t Ag located at the level of (and immediately below) the E Zone skarn horizon.

Drill hole 30-1109, also located near the eastern margin of the 2024 MRE model, cut unmineralized material to a depth of about 460 metres, followed by three mineralized intervals to a vertical depth of 860 metres. These also include a higher-grade interval of 133.7 metres averaging 1.04% Cu and 6.48 g/t Ag located in skarn and porcellanites above and below the E Zone skarn horizon.

Both 30-1106 and 30-1109 suggest potential for the presence of a higher-grade tabular deposit around the E Zone horizon that, when combined with historical drilling data, indicates a potential extension eastward towards the previously mined E-32 Zone over a lateral distance of 800 metres.

Drill hole 30-1110, located on top of Copper Mountain near the central part of the 2024 MRE model, intersected 1091.5 metres averaging 0.20% Cu, 1.52 g/t Ag, and 0.017% Mo (0.28% CuEq), including 735.6 metres averaging 0.20% Cu, 1.50 g/t Ag, and 0.015% Mo (infill) and 355.9 metres averaging 0.21% Cu, 1.55 g/t Ag, and 0.021% Mo (expansion), extending mineralization to a vertical depth of 1100 metres and again confirming continuity of mineralization in the core of the deposit.

Drill hole 30-1111, located immediately west of Copper Mountain near the southern lip of the pit, intersected 304.5 metres (from surface) averaging 0.17% Cu and 0.80 g/t Ag followed by three more intersections that included expansion at depth of 206.3 metres averaging 0.33% Cu, 2.39 g/t Ag, and 0.016% Mo, extending mineralization in this area to a vertical depth of 936 metres. The central porphyry intrusion was then intersected and returned 76 metres averaging negligible copper (0.08% Cu) but significant molybdenum (0.023% Mo).

Mineralization at Gaspé Copper is of porphyry copper/skarn type and occurs as disseminations and stockworks of chalcopyrite with pyrite or pyrrhotite and minor bornite and molybdenite. At least five retrograde vein/stockwork mineralizing events have been recognized at Copper Mountain, which overprint earlier prograde skarn and porcellanite-hosted mineralization throughout the Gaspé Copper system. Porcellanite is a historical mining term used to describe bleached, pale green to white potassic-altered hornfels. Subvertical stockwork mineralization dominates at Copper Mountain whereas prograde bedding-replacement mineralization, that is mostly stratigraphically controlled, dominates in the area of Needle Mountain, Needle East, and Copper Brook. High molybdenum grades (up to 0.5% Mo) were locally obtained in both the C Zone and E Zone skarns away from Copper Mountain.

The 2022 to 2024 Osisko Metals drill programs were focused on defining open-pit resources within the Copper Mountain stockwork mineralization ( see May 6, 2024 MRE press release ). Extending the resource model south of Copper Mountain into the poorly-drilled prograde skarn/porcellanite portion of the system subsequently led to a significantly increased resource, mostly in the Inferred category ( see November 14, 2024 MRE press release ).

The current drill program is designed to convert the November 2024 MRE to Measured and Indicated categories, as well as test the expansion of the system deeper into the stratigraphy and laterally to the south and southwest towards Needle East and Needle Mountain respectively. The November 2024 MRE was limited at depth to the base of the L1 skarn horizon (C Zone), and all mineralized intersections below this horizon represent potential depth extensions to the deposit, to be included in the next scheduled MRE update in Q1 2026.

All holes are being drilled sub-vertically into the altered calcareous stratigraphy, which dips 20 to 25 degrees to the north. The L1 (C Zone) the L2 (E Zone) skarn/marble horizons were intersected in most holes, as well as intervening porcellanites that host the bulk of the disseminated copper mineralization.

Explanatory note regarding copper-equivalent grades

Copper Equivalent grades are expressed for purposes of simplicity and are calculated taking into account: 1) metal grades; 2) estimated long-term prices of metals: US$4.25/lb copper, US$20.00/lb molybdenum, and US$24.00/oz silver; 3) estimated recoveries of 92%, 70%, and 70% for Cu, Mo, and Ag respectively; and 4) net smelter return value of metals as percentage of the price, estimated at 86.5%, 90.7%, and 75.0% for Cu, Mo, and Ag respectively.

Qualified Person

The scientific and technical content of this news release has been reviewed and approved by Mr. Bernard-Olivier Martel, P. Geo. (OGQ 492), an independent ‘qualified person’ as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (‘NI 43-101’).

Quality Assurance / Quality Control

Mineralized intervals reported herein are calculated using an average 0.12% CuEq lower cut-off over contiguous 20-metre intersections (shorter intervals as the case may be at the upper and lower limits of reported intervals). Intervals of 20 metres or less are not reported unless indicating significantly higher grades . True widths are estimated at 90- 92% of the reported core length intervals.

Osisko Metals adheres to a strict QA/QC program for core handling, sampling, sample transportation and analyses, including insertion of blanks and standards in the sample stream. Drill core is drilled in HQ or NQ diameter and securely transported to its core processing facility on site, where it is logged, cut and sampled. Samples selected for assay are sealed and shipped to ALS Canada Ltd.’s preparation facility in Sudbury. Sample preparation details (code PREP-31DH) are available on the ALS Canada website. Pulps are analyzed at the ALS Canada Ltd. facility in North Vancouver, BC. All samples are analyzed by four acid digestion followed by both ICP-AES and ICP-MS for Cu, Mo and Ag.
