White Gold Corp. (TSX-V: WGO) (OTCQX: WHGOF) (FRA: 29W) is pleased to announce an updated Mineral Resource Estimate for its flagship White Gold project located approximately 95 km south of Dawson City in west-central Yukon, Canada. The updated mineral resource was initiated following recent new modelling for the Golden Saddle and Arc deposits, including optimization and reinterpretation of the gold bearing zones (Figure 2 & 3). The primary result of these efforts was greater continuity of the zones than previously captured in the model. The updated MRE shows a significant increase in total gold ounces, including a 44% increase (529,300 ounces) in indicated resources for a new total of 1,732,300 ounces of gold and a 13.4% increase (149,300 oz) in inferred resources for a new total of 1,265,900 ounces of gold⁽¹⁾. The gold resources at the White Gold Project are near surface, almost entirely captured within open pits, and remain open for expansion in multiple directions with additional exploration opportunities to increase total resources via targets within close proximity (Figure 4). The ongoing 2025 exploration program (Figure 5 & 6) has been designed to deliver further increases to the size of the resource and to advance technical understanding in support of a Preliminary Economic Assessment (“PEA”). These results form part of the Company’s work program supported by strategic partners including Agnico Eagle Mines Limited.

The updated Mineral Resource Estimate continues to demonstrate the size, quality, and growth potential of the Company’s flagship project. The new modelling of the Golden Saddle and Arc deposits showcase improved geological continuity, stronger grade distribution, and optimized pit designs that collectively enhance overall project economic potential. This significant advancement further positions the project as a leading gold resource in both size and grade in a top-ranked global mining jurisdiction, with substantial opportunity for additional growth.

“The remodelling of the Golden Saddle and Arc deposits has more effectively and efficiently captured mineralization across the geological domains, resulting in a very meaningful addition to the resource,” said Dylan Langille, Vice President of Exploration for White Gold Corp. “Building on this success, our 2025 exploration program is designed to drive further significant growth through drilling under-explored parallel mineralized zones as well as cost-effective sampling of unsampled hanging wall and footwall zones in historic drill core. This season’s work is aimed at demonstrating substantial value that remains untested within the existing deposits of the White Gold portfolio which we believe has the potential to grow significantly with addition drilling.”

“Today’s announcement of the significant increase in gold resources at our flagship White Gold Project is another major milestone for the company,” stated David D’Onofrio, Chief Executive Officer for White Gold Corp. “The updated resource also further highlights the strong growth potential of our near surface deposits which remain open in multiple directions with numerous prospective targets in close proximity that also warrant drill testing based on their exploration results to date. With 1.7 million ounces indicated plus 1.3 million ounces inferred now defined, and significant growth potential, we have successfully further established the White Gold project as leading large scale high grade open pittable gold deposit in a tier-one jurisdiction in Canada. We look forward to further increasing the scale of the project as we advance it to a PEA to demonstrate its economic potential, while also working to unlock additional value across our extensive land package in the prolific and under explored white gold district.”

Mineral Resource Estimate Details

Table 1. White Gold Project, Yukon Territory, Mineral Resource Statement, ACS August 19, 2025.

The current MRE for the White Gold project was carried out by Arseneau Consulting Services of Vancouver, B.C. and is reported in accordance with the guidelines of the Canadian Securities Administrators National Instrument 43-101 (“NI 43-101”) and has been estimated in conformity with generally accepted Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) “Estimation and Mineral Resource and Mineral Reserve Best Practices” guidelines. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

The MRE presents updated estimates for the Golden Saddle, Arc, Ryan’s Surprise and VG deposits.

The basis for the updated MRE at the Golden Saddle and Arc deposits was a re-interpretation which allowed wireframes to enclose mineralized zones with composited assays greater than 0.20 grams per tonne gold. Historical modeling encompassed gold intersections with assays greater than 0.4 g/t gold. The wireframes are therefore grade shells guided by the geology. Wireframes were constructed by White Gold using Leapfrog Geo. All wireframes were verified, validated and accepted by the QP.

The updated MRE was prepared using a block model approach using ordinary kriging interpolation for the Golden Saddle, Arc and VG deposits and inverse distance squared interpolation for the Ryan’s Surprise deposit. Block model sizes varied between deposits as follows: Golden Saddle and Arc (10 m); Ryan’s Surprise (5 – 10 m); and VG (10 – 20 m). GEMS 6.8.4 software was used for generating gold mineralization solids, a topography surface, and resource estimation. Statistical analysis and resource validations were performed using non-commercial software and with Sage2001. Near surface resources were constrained using GEOVIA Whittle pit optimization software. Pit slopes in rock were assumed at 50° and the MRE assumes a long-term gold price of US$2,250 per ounce. Gold recoveries used were 92% for the Golden Saddle and VG deposits, and 85% for the Arc and Ryan’s Surprise deposits. Gold recoveries are based on metallurgical test work results for the Golden Saddle and Arc deposits and are assumed for the Ryan’s Surprise and VG deposits based on their close similarities to the Arc and Golden Saddle deposits, respectively.

A technical report to support the MRE for the White Gold project, prepared in accordance with NI 43-101, will be filed on SEDAR+ (https://www.sedarplus.ca/) and the Company’s website (https://www.whitegoldcorp.ca/) within 45 days of the issuance of this news release.

2025 Exploration Programs and Growth Potential

Further significant expansion potential has been identified and is being advanced through the Company’s 2025 Exploration Program (see Company press release dated August 6, 2025). This program is specifically designed to build on the positive momentum of the updated resource estimate by targeting areas of untested or underexplored mineralization and advancing technical studies in support of a future PEA.

Golden Saddle

2025 diamond drilling at Golden Saddle will target a high-grade footwall breccia zone first intersected in historic drilling. While previous drilling confirmed the presence of this mineralization, it has not been systematically explored. Planned drilling will also test the hanging wall, where historic drill holes encountered mineralization that remains largely unsampled, offering a cost-effective opportunity to add near-surface ounces.

Arc

At Arc, drilling will focus on testing the down-dip extension of mineralized zones with the dual purpose of expanding the current resource and providing fresh material for metallurgical test work programs. This work will help refine recovery assumptions and contribute to the economic studies required for a PEA.

Relogging & Resampling Program

In parallel, a systematic relogging and resampling program is underway on historical drill core. This initiative is targeting previously unsampled quartz-carbonate vein–bearing intervals in both the footwall and hanging wall host rocks adjacent to known mineralized domains. These efforts are expected to cost-effectively capture additional mineralization that was not included in prior models, further strengthening the resource base.

Resources & Opportunities in the White Gold District

West-central Yukon is host to several highly prospective mineral districts, including the White Gold, Dawson Range, Klondike, and Sixtymile districts. The Klondike was the epicenter of the historic Klondike Gold Rush in 1896, with over 20 million ounces of placer gold production having occurred in the region since that time.

The Company’s property portfolio, which covers large portions of the White Gold District, was assembled by renowned prospector Shawn Ryan, and represents the largest contiguous claim package in the region.

Two significant advanced-stage projects border the Company’s claims to the south:

• The Coffee Project, owned by Newmont Corporation, hosts Measured and Indicated Resources of 50.2 Mt grading 1.28 g/t Au for 2.17 million ounces of gold, and Inferred Resources of 6.7 Mt grading 1.14 g/t Au for 0.23 million ounces gold^{(2) (3)}.
• The Casino Project, owned by Western Copper and Gold Corporation, contains Measured and Indicated Resources of 2,490.7 Mt grading 0.18 g/t Au, 0.14% Cu for 14.8 million ounces of gold and 7.6 billion pounds of copper, and Inferred Resources of 1.4 Mt grading 0.14 g/t Au, 0.14% Cu for 6.3 million ounces of gold and 3.1 billion pounds of copper⁽⁴⁾⁽³⁾.

The region has seen significant investment by major mining companies in recent years, and the Yukon is consistently ranked among the top 10 global mining jurisdictions on the Fraser Institute’s Investment Attractiveness Index.

All four of White Gold’s near-surface deposits, which form the White Gold Project, are interpreted to represent structurally controlled orogenic gold systems. These deposits collectively form the Company’s gold resource base in the heart of its extensive land package and remain open for expansion. Additional information on each of these deposits can be found below.

Golden Saddle Deposit

The Golden Saddle deposit is located 95 km south of Dawson City on the Company’s White Gold property, which is supported by the fully operational Thistle exploration camp with airstrip and barge access, and up to 100-person capacity. The deposit consists of the GS Main, GS Footwall and GS West zones and together the zones define mineralization over a 1,500 m strike length and up to 725 m down dip. Currently, the GS Main is the most significant zone in terms of estimated ounces and overall grade; containing approximately 95% of the Indicated ounces within the overall Golden Saddle deposit. GS Main Zone which contains a consistent high-grade core of 12.3 million tonnes grading 2.84 g/t representing 1,100,000 ounces in the Indicated category and 1.4 million tonnes grading 2.03 g/t for 93,000 ounces in the inferred category at a 1.0 g/t cut-off. At a 3.0 g/t cut-off, the high-grade core contains 4.4 million tonnes grading 4.88 g/t for 695,000 ounces in the indicated category and 269,000 tonnes grading 4.07 g/t for 35,000 ounces in the inferred category. Gold mineralization at the Golden Saddle deposit is hosted in a meta-volcanic and meta-intrusive assemblage broadly consisting of felsic orthogneiss, amphibolite, and ultramafic units. Gold generally occurs as micron-scale blebs along fractures or encapsulated by pyrite, and as visible gold (less than 5 mm in size) located as free grains in quartz. Mineralization is present in quartz veins and stockwork or breccia with disseminated pyrite. Drill hole intersected gold mineralization is spatially co-incident with structures, and structures or faults which are interpreted to be the primary conduits for hydrothermal fluids responsible for gold deposition. The thicknesses of the mineralization and breccia zones are variable from 5 m to over 50 m, and they pinch and swell along strike. A consistent higher-grade core (> 3 g/t Au) occurs within the main zone at Golden Saddle. Gold mineralization at the Golden Saddle deposit remains open in all directions and is known to extend beyond the limits of the current resource estimate, however, the mineralization in these areas does not currently meet the criteria to be classified as Mineral Resources.

Arc Deposit

The Arc deposit is located approximately 400 m south of the Golden Saddle and consists of two zones, the Arc Main and Arc Footwall zones, both trending E-NE and dipping to the north at approximately 50 degrees. Mineralization at the Arc has been defined over 1,200 m in strike length and up to 450 m down dip with mineralization open along strike and down dip. Gold mineralization at the Arc deposit is less well understood than the Golden Saddle, which is partially a function of drilling at the Arc deposit being more widely spaced. Gold mineralization is hosted within a meta-sedimentary sequence dominated by banded (graphitic) quartzite and interbedded pelitic biotite schist that is cross-cut by numerous felsic to intermediate dikes and sills.

Gold mineralization appears to be focused within breccia and shear zones that have been affected by hydrothermal alteration and sulphide mineralization. Drilling has defined an upper main zone as well as a lower footwall zone of anomalous gold but of lesser tenure than the main upper zone. Mineralization remains open to the east, west and at depth. The occurrence of gold at Arc is not well understood but appears to be associated with disseminated and veined pyrite, arsenopyrite and graphite.

Ryan’s Surprise Deposit

Ryan’s Surprise is located 1.5 km west of the Golden Saddle deposit, along a 6.5 km long x 1 km wide north-northwest trend of anomalous gold and arsenic in soils (“Ryan’s Trend”), which also hosts several other prospective early-stage targets in close proximity with significant surface gold mineralization and represent further potential for expansion of this project. Gold mineralization at the Ryan’s Surprise deposit is primarily hosted within a meta-sedimentary sequence dominated by banded (graphitic) quartzite and interbedded pelitic biotite schist cross-cut by numerous felsic – intermediate dikes and sills.

Gold mineralization appears to be focused within breccia and shear zones that have been affected by hydrothermal alteration and sulphide mineralization. Recent drilling has defined multiple subparallel zones that are host to gold-bearing sulphide mineralization including arsenopyrite and pyrite, and range in true width from < 1 m to in some instances, > 10 m. The mineralization footprint at the Ryan’s Surprise deposit measures approximately 550 m north-south by 500 m east-west to a vertical depth of 650 m remains open along strike and at depth. Metallurgical work, gold characterization and deportment studies are required to further determine accurate gold recoveries. However, host rocks, alteration and sulphide mineralization at Ryan’s Surprise display many similarities to the Arc Deposit.

VG Deposit

The VG deposit is located approximately 85km south of Dawson City and 11km north of the Golden Saddle deposit. Gold mineralization at the VG deposit is hosted in quartz ± carbonate veins, stockwork and breccia zones, and pyrite veinlets, including cubic pyrite and visible gold, associated with intense-quartz-carbonate-sericite alteration, pervasive K-spar and hematite emplaced along en-echelon faults or shear zones. Visually, the style of gold mineralization and alteration appears identical to the Golden Saddle deposit, along with similar dominant host rocks of biotite-feldspar (± augen)-quartz gneisses. To date, no metallurgical testwork has been performed on the VG mineralization, however given its close similarities to Golden Saddle, gold recoveries are assumed to be similar. Opportunities exist at the VG deposit to quickly upgrade a significant portion of Inferred Resources to Indicated, as well as for expansion of gold mineralization at depth and along strike. There are also several other prospective targets on the property which have received limited exploration work and offer potential for additional discoveries.

Qualified Persons, Technical Information and Quality Control

The MRE for the White Gold Project was prepared by Dr. Gilles Arseneau of Arseneau Consulting Services (ACS), an Independent Qualified Person (“QP”) as defined under NI 43-101, who has reviewed and approved the contents of this news release.

QA/QC

White Gold’s drill core sampling consisted of collecting samples over 0.50 m to 2.50 m intervals (depending on lithology and style of mineralization) over the entire hole length. RC samples were collected at continuous 1.5 m intervals. All drill core was cut in half using a diamond saw, with half of the core placed in sample bags and the other half returned to the core box. Standard, blank, and duplicate samples were inserted into both the drill core and RC sample streams at regular intervals to meet a designated QA/QC sample insertion rate. All samples were organized into batches, flown via fixed-wing aircraft from camp, and transported via courier to an ISO-certified laboratory for analysis.
