WHITE GOLD CORP. MAKES NEW HIGH-GRADE COPPER DISCOVERY WITH BEDROCK SAMPLES UP TO 0.96% COPPER AT LOST PUP TARGET AND HIGHLIGHTS PROSPECTIVITY OF THE TITAN - LOST PUP MINERALIZED TREND ON ITS HEN PROPERTY, YUKON, CANADA

White Gold Corp. has discovered copper mineralization at the newly identified Lost Pup target on its 100-per-cent-owned Hen property in west-central Yukon, Canada. Initial bedrock sampling from the showing, which was initially exposed by placer mining operations, returned values up to 0.96 per cent copper, with additional samples grading 0.94 per cent, 0.61 per cent and 0.52 per cent Cu from chalcopyrite-bearing quartz veins and fracture zones.

The Lost Pup showing is located four kilometres southeast of the company's Titan target, where historic drilling has returned high-grade gold intercepts including 37.4 grams per tonne gold over 1.5 metres within a broader interval of 9.48 g/t Au over 6.25 metres in diamond drilling. Both Lost Pup and Titan are situated along a six-kilometre-long, north-northwest-south-southeast-oriented structural thrust corridor coincident with a prominent regional magnetic gradient, suggesting a district-scale mineralized trend with significant potential for both high-grade gold and large-scale copper-gold Minto systems, which also hosts the Titan, Guilder and other known targets.

The discovery highlights the potential for intrusive-related copper mineralization along the Titan structural corridor within the Hen property.

David D'Onofrio, chief executive officer, commented: "The discovery of high-grade copper mineralization at Lost Pup is an exciting new development and yet another example of the abundant opportunities, in addition to the company's large and growing high-grade gold resource, within our truly district-scale property portfolio comprised of 21 properties covering over 300,000 hectares in the prolific and under explored White gold district, which is now seeing a renaissance of interest based on recent exploration success and the advancement of significant projects in the area. The discovery's location along the same mineralized corridor as our high-grade Titan gold discovery makes it even more significant. The combination of high-grade gold, widespread copper mineralization and a classic porphyry geochemical signature provides compelling evidence that this structural trend is a major mineralizing system. This new discovery expands the footprint of this system and underscores the vast potential of the Hen property, which is ideally located in the heart of the White gold district."

Highlights:

• New high-grade copper discovery: New Lost Pup showing discovered on the Hen property, with rock samples assaying up to 0.96 per cent Cu, with additional samples grading 0.94 per cent, 0.61 per cent and 0.52 per cent Cu;
• Minto copper system signatures: mineralization is hosted in chalcopyrite-bearing quartz veins and fracture zones with azurite and malachite exposed in creek outcrop; previous drilling at the Titan target also confirmed the presence of significant copper-gold porphyry system mineralization in the area;
• Proven high-grade gold corridor: the showing lies on the same structural trend as the Titan target, where past drilling returned 9.48 g/t Au over 6.26 m, including 37.4 g/t Au over 1.5 m (HENTTN20D-003);
• Polymetallic signature: the mineralized system at Titan displays a strong copper, gold, bismuth and molybdenum geochemical signature, which is characteristic of a large-scale intrusion-related gold system; the Lost Pup showing exhibits a similar copper-silver-bismuth signature, with samples assaying up to 15.1 g/t silver, strengthening its connection to the wider mineralizing event;
• Strategic location: the Titan-Lost Pup corridor is located approximately 900 metres from a mapped occurrence of the Late Cretaceous Sulphur Creek intrusive suite, which is known to be associated with copper-gold mineralization across the district, including the Casino and Minto deposits, as well as the Coffee and Golden Saddle deposits; Lost Pup lies along a north-northwest-south-southeast thrust corridor associated with a regional magnetic high-low contact, which also hosts White Gold's Titan and Guilder targets and other known targets;
• Coming catalysts: additional results from the company's exploration program on its district-scale portfolio to be released in due course, along with further details on the company's planned spinout of its critical mineral assets, maiden preliminary economic assessment, and finalization and announcement of the company's 2026 exploration program; the coming 2026 program will be largest in the company's history and is being designed with the objective of meaningfully increasing the size of the company's known large high-grade gold resource and following up on and/or make new gold and critical mineral discoveries across the company's district-scale land package.

Discovery of the Lost Pup copper showing

The Lost Pup showing was identified late in the 2025 exploration program following reports of copper mineralization exposed by placer mining activity within a creek channel on the Hen property. Prospecting and rock sampling confirmed the presence of copper mineralization in altered bedrock exposed in the area. The Lost Pup showing is located approximately 20 km from the company's flagship White gold project and approximately 20 km from the planned Northern Access Gateway major arterial road. The White gold project hosts four near-surface gold deposits, which collectively contain an estimated 1,732,300 ounces of gold in indicated resources (35.2 million tonnes grading 1.53 g/t Au) and 1,265,900 ounces of gold in inferred resources (32.2 million tonnes grading 1.22 g/t Au), with significant expansion potential on the resource itself and in the immediately surrounding area. The Golden Saddle Main zone hosts a consistent high-grade core containing 1.1 million ounces indicated (12.3 million tonnes at 2.84 g/t Au) and 93,000 ounces inferred (1.4 million tonnes at 2.03 g/t Au) at a 1.0 g/t cut-off. At 3.0 g/t cut-off, this core contains 695,000 ounces indicated (4.4 million tonnes at 4.88 g/t Au) and 35,000 ounces inferred (269,000 tonnes at 4.07 g/t Au) (see the company's news release dated Oct. 6, 2025).

Chip sampling across the exposure returned copper values up to 0.96 per cent Cu, with several additional samples grading 0.94 per cent, 0.61 per cent and 0.52 per cent Cu. The mineralization occurs within quartz veins and fracture zones containing chalcopyrite and pyrite, with abundant secondary copper minerals including malachite and azurite developed in the near-surface oxidation zone.

Several samples also returned elevated silver values of up to 15.1 g/t Ag, which correlate positively with copper and may indicate the presence of primary sulphide mineralization within the system. The mineralization is hosted in structurally controlled quartz veins and fracture zones, and the rock samples also returned minor bismuth and trace molybdenum enrichment, consistent with hydrothermal mineralization potentially related to nearby intrusive rocks.

Structural setting

The Lost Pup showing is located within a structurally complex area where several regional fault systems converge, including the Topaz and Vertigo fault zones, which trend west-northwest-east-southeast, and the regional Fright fault zone, which trends northeast-southwest across the district. These structures intersect the north-northwest-south-southeast-oriented Titan thrust zone, which coincides with a prominent regional magnetic high-low contact interpreted from airborne magnetic data.

Several of the company's other exploration targets, including Guilder, Titan and Lost Pup, occur along this north-northwest-south-southeast structural corridor, suggesting it may represent a district-scale mineralized trend associated with intrusive activity along the magnetic gradient. Notably, this corridor closely follows a pronounced regional magnetic high-low contact interpreted from airborne magnetic data, suggesting the structure may mark an important lithologic or intrusive boundary that acted as a pathway for hydrothermal fluids.

Copper-gold dominant targets appear to align along this thrust corridor, while several high-grade gold targets occur along intersecting northeast-southwest fault zones across White Gold's JPR property, including the Vertigo, Stage Fright, Sabotage, Frenzy and X-Man targets located to the northeast. Additional gold occurrences extend southwest across the Yukon River onto the company's QV property, including the Chris Creek, Diego, Shadow and Tetra targets. The Chris Creek target appears to be structurally, geochemically and lithologically similar to the VG and Golden Saddle deposits.

The presence of bismuth associated with several gold targets across the district may indicate a broader intrusive-related hydrothermal system, with structural controls influencing the spatial distribution of copper-rich and gold-dominant mineralization.

Relationship to Sulphur Creek and Long Lake intrusions

The Lost Pup showing occurs approximately 900 metres southwest of a mapped occurrence of the Sulphur Creek intrusive suite, which is interpreted to represent part of a Late Cretaceous intrusive event associated with mineralization in the region. The combination of this intrusive suite with regional structural corridors is similar to the geological controls recognized at several deposits across the region, including Golden Saddle (White Gold), Coffee (Fuerte Minerals), Minto (Selkirk Copper) and Casino (Western Copper and Gold Corp.).

The proximity of the showing to the mapped intrusive occurrence, together with the observed chalcopyrite-bearing quartz veins and associated copper-silver geochemical signature, suggests the Lost Pup mineralization may represent a structurally controlled hydrothermal occurrence related to intrusive activity within the Titan structural corridor.

Exploration potential

The discovery of copper mineralization at the Lost Pup target highlights the potential for additional copper-bearing systems within the Hen property and supports the prospectivity of the Titan structural corridor and definitely warrants follow-up exploration in the coming season.

Future exploration work will focus on detailed geological mapping, additional rock and soil geochemical sampling, structural interpretation, integration of geophysical data sets, and evaluation of potential drill targets to better understand the extent and controls of mineralization at Lost Pup and along the broader structural corridor.
