Vancouver, British Columbia–(Newsfile Corp. – June 9, 2026) – West Point Gold Corp. (TSXV: WPG) (OTCQX: WPGCF) (FSE: LRA0) (“West Point Gold” or the “Company”) is pleased to announce drill results from the high-grade zone at Northeast (NE) Tyro, part of the recently completed drill program at its flagship Gold Chain Project in Arizona. The two holes reported herein, GC26-134 and GC26-137, further confirm and validate the high-grade discoveries made via reverse circulation drilling (“RC”) at the NE Tyro Zone in drill core. The highlight intervals of 9.06 grams per tonne (“g/t”) gold (“Au”) over 19.7 metres (“m”) and 3.2 g/t Au over 35.7m are in line with or exceed many prior results and continue to showcase the robust widths and high-grade tenor of the system at NE Tyro.

The 2025/2026 drilling campaign, comprising RC (18,683.3m) and core (2,395.7m), has now been completed, with a total of 21,079 m drilled. Approximately 7,025m of assays are pending and will be released over the next couple of months. With this year’s drilling now complete, the team will focus on integrating the results into the Company’s maiden mineral resource estimate (“MRE”), expected to be released later in 2026.

Highlights:

• Hole GC26-134 returned 19.7m of 9.06 g/t Au from 95.8 to 115.5m, about 20m above GC25-059 (15.3m of 7.02 g/t Au).
• Hole GC26-137 returned 35.7m of 3.2 g/t Au from 53.2 to 88.9m, including 10.2m of 10.23 g/t Au, about 20m above GC25-047 (38.1m of 4.86 g/t Au including 10.7m at 8.64 g/t Au).
• The two core holes were drilled across the high-grade zone previously defined by reverse-circulation drilling to provide improved confidence and context for the geologic, geometric, and gold-grade models.

“These results continue to highlight the high-grade nature of NE Tyro and the potential of this zone. Importantly, these core holes correlate well with proximal RC holes, providing confidence that the practices used for our RC drilling are producing representative results. With the 21,079m completed in the most recent drill campaign, we are now focused on analyzing the results for both our upcoming maiden resource estimate at Tyro Main and NE Tyro and the planning for our next drill program,” stated Derek Macpherson, President and CEO.

Summary
Both Holes GC26-134 and GC26-137 targeted areas proximal to defined high-grade gold mineralization from previous drilling (Figures 3 and 4). Aside from Hole GC24-034 (Figures 2 and 4), all holes in this area have been RC. To ensure that best practices are being followed and that the RC drilling is producing consistent results, it was deemed important to cross-reference higher-grade portions with core where detailed documentation of recovery, RQD, vein styles, textures, and density occurred. In summary, these two holes support the emerging geologic and grade models generated to date and improve the definition of the high-grade gold mineralization in the NE Tyro zone at the Company’s Gold Chain project in Arizona. The two holes comprising this release represent 298.4m of the now completed 21,079m drill program.

Both holes share several similarities in sectional view (Figures 3 and 4). The NE Tyro vein is a robust, fairly uniform structure that dips to the SE at 70^o to 75^o, and ranges in width from 15 to 25 metres. The width of the mineralized package varies relative to the development of quartz veinlets and stockwork in the hanging wall (“HW”) and ‘outboard’ from the principal quartz vein/breccia at the footwall (“FW”). Precambrian granite, along with lenses or ‘xenoliths’ of gneiss, schist, and amphibolite, is the host rock. Perhaps most importantly, several intercepts are hosted by or adjacent to fine-grained (aphanitic) felsic dike (Miocene), likely rhyolite, forming quartz-calcite-cemented breccia and stockwork. This spatial coincidence may reflect a preference for the gold-bearing fluids to follow the dikes (more brittle) and/or the contact with the hosting Precambrian (likely broken and faulted). The modeling of these features in the upcoming weeks will provide greater insight into deeper targets.

As shown in Figures 2 through 5, both Holes GC26-134 and GC26-137 traverse the vein at about the same elevation (760 – 790m ASL) or about 100m below the surface. Quartz >> calcite veinlets in propylitized (chlorite + quartz + pyrite) Precambrian rocks define the distal zone of veining and increase with depth from a few percent to 25% with occasional gold values. The main mineralized zone commences with moderate to strong quartz-calcite veinlets, stockwork and breccia giving way to a multi-stage breccia zone up to the FW contact (Figures 5 and 6). Evidence of faulting (Miocene) and shearing in the Precambrian rocks suggest a pre-Tertiary origin for the controlling structures.

Figure 3. Geologic section drawn along GC26-134 showing vein and spatial relation to GC21-013, GC25-087, GC25-059, GC25-086, GC26-161 and GC26-168 and the surface.

Veins and breccia composing the NE Tyro vein are multi-stage and comprised of quartz-chalcedony-calcite (bladed)-adularia with only trace amounts of pyrite (Figures 5 and 6). Surface-related oxidation is minimal and only seen along post-mineral fractures. However, local intervals or breccia fragments of weakly iron-stained bladed calcite and quartz along with fine, quartz-hematite veinlets suggest an event of hydrothermal oxidation. Bladed calcite or “lattice texture” has developed in several stages and ranges from delicate bands within crustiform/coliform-banded chalcedony to coarse, angular fragments in late-stage breccia. Native gold (Figure 7) has been observed within minute dendritic growths of a black opaque, perhaps electrum or a sulfosalt. The documentation of these features may prove to be important as the Company evaluates events related to gold deposition at greater depths.

Breccia textures are prevalent in these holes and were developed during multiple events. Aside from fault breccia observed at the vein’s FW contact, the vein package consists of broad intervals of weak (further into the HW) to strong stockwork/breccia composed of fine- (chalcedony) to medium- (sucrosic) to coarsely-crystalline (comb) quartz veins and veinlets with subordinate amounts of calcite dominantly in a bladed habit and native gold (see Figure 7); adularia (?) likely occurs in select bands or vein fragments revealing a tan to light pink coloration. Some breccia masses are ‘jigsaw’ in character, suggesting little or no fragment transport. Other breccias are fine-grained, heterolithic, and reveal fluidal or ‘streaming’ textures suggesting considerable transport (and energy). The dominance of breccias at the FW portion of the vein complex suggests both recurrent movement and explosive events likely related to deeper fluid boiling and potential gold deposition.

Vancouver, British Columbia–(Newsfile Corp. – June 9, 2026) – Riverside Resources Inc.  (TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY) (“Riverside” or the “Company”), is pleased to announce that the Second Phase drill program has commenced at the Union Project in northwest Sonora, Mexico. This work is being carried out by the Company operating in partnership with Questcorp Mining Inc. (CSE: QQQ), which is earning into the project through an option agreement from Riverside (press release, May 6, 2025).

Program Highlights

• Fully Funded Program Underway: A ~1,500-metre diamond drill program across 8 to 10 holes, each averaging 180 metres in depth, is fully funded and requires no near-term dilutive financing.
• Expanding Phase 1 Discoveries: Drilling is designed to expand zones of mineralization, including those intercepted during the Phase 1 program with results announced in January 2026, and to test new areas developed during the winter 2026 field program.
• District-Scale Target Testing: The program tests new targets and explores areas surrounding multiple historical mine workings across the 25 km² La Union project area.
• Two Mineralization Styles: Holes will test both the sediment-hosted gold mineralization identified in Phase 1 and carbonate-hosted replacement deposit (CRD) gold-silver-zinc mineralization, where gold is associated with mantos, chimneys, and structural zones.
• Structurally Targeted Drilling: Angled holes are oriented to intersect stratigraphic and structural targets at high angles, as is typical in CRD systems. Structural features interpreted as potential mineralizing conduits are a key focus of the program for high grade gold and zinc.
• Advanced Target De-Risking: Final drill positioning integrates property-wide structural mapping, 248 line-km of drone aeromagnetic coverage, and a recently completed property-wide induced polarization (IP) survey.
• Geological Analog: La Union’s CRD and sediment-hosted gold systems share geological characteristics with significant deposits in northern Mexico and the southwestern United States.
• Continuous News Flow: Exploration is coordinated with partner Questcorp Mining Inc. (CSE: QQQ), supporting milestone-driven news flow through summer 2026.

The exploration work over the past four months by Riverside has improved the understanding of the structural geology and stratigraphy of the project. The Union district lies along the flanks of this range with host stratigraphy that has now been studied for target layers that can host large bulk tonnage gold potential as found in Paleozoic sedimentary host units in Nevada and similarly in Sonora, Mexico. The improved mapping and detailed sampling underground delivered a better understanding of the chimney and manto aspects which include the structural feeder zones and post mineral faults. The exploration target focus is for a large potential gold discovery that expands from previous smaller scale mine operations on the property. Phase 2 drilling is intended to test the new concepts and expand beyond these past mining sites.

“We are exceptionally well-positioned to move ahead with this second phase of drilling, deploying 1 to 2 high-impact holes per target area to evaluate the deep root potentials of these sediment-hosted and CRD targets well beyond legacy past-mining boundaries,” said John-Mark Staude, CEO of Riverside Resources. “Advanced structural synthesis led by Riverside’s Alejandro Gracida has successfully pinned down the primary northwest-trending fault structures, which are interpreted to act as the primary structural plumbing and corridors for wide zones of high-grade feeder gold mineralization. The comprehensive IP Survey completed last week feeds directly into our real-time targeting models, and the program is advancing with rapid operational efficiency.”

“Today marks a transformative milestone for Questcorp as we transition from a successful target generation phase into aggressive discovery drilling,” said Saf Dhillon, President & CEO of Questcorp Mining. “Over the past several months, our integrated technical teams alongside our partners at Riverside have unlocked the true scale of the La Union district. Every layer of new data, from structural mapping to our newly completed IP geophysics, points toward a vast, interconnected mineralized system that remains largely untouched at depth.”

The drill program covers more than five target areas. It begins with follow-up at the Union Mine, where prior drilling resolved key stratigraphic and orientation questions, allowing this round to step out into ground adjacent to past mining. Underground work identified large-scale alteration and indications of a mineralized system, making this one of several priority areas. The high-grade gold-silver chip channel samples taken underground at the Union Mine will now be followed up with drilling.

The second phase of drilling will follow up on Phase 1 results and on the broader targets developed through the spring 2026 field exploration program. Phase 2 will consist of one to three holes per area, primarily for orientation and to expand on the Phase 1 drilling. Follow-up drilling beyond Phase 2 is planned and can be expanded based on results and on the geophysics completed over the past several months. The detailed stratigraphy, lithology, and structural framework developed by the Riverside geological team specifically targets high-grade, favorable horizons for sediment-hosted gold mineralization and CRD. The five target areas outside of the Union Mine are as follows:

• Union Main Mine – Jales Area – The program will use targeted drill holes to test limestone and other carbonate stratigraphic hosts within the Clemente Formation, with the potential to reach the underlying Caborca Formation. These units are considered the primary hosts for replacement-style mineralization and have gold, silver and zinc in oxide mineralization in the mine and could be potentially extensive.
• North Union Mine – Negra Area – The initial focus of the program will be on testing structural interpretations of NW fault feeder zones. The new Negra zone has provided gold mineralization in samples and now can be a new drill area which has never been tested.
• Luis Hill- Alej Hill Area – The upper part of the Clemente Formation revealed sediment hosted gold in Phase 1 drilling allowing the follow up work to potentially expand upon that. The geology team has carefully mapped the stratigraphy and structure geology northward for over 2 kilometers and this target could have vast potential. Careful structural mapping has found some critical cross feeder structures which the team will now target during this phase.
• Cobre Mine Area – The Clemente Formation is the primary host unit, and structural features combined with areas of past mining provide multiple target zones that can now be followed up after Phase 1 drilling. The careful 1:1000 mapping by Gracida across the NW features, along with detailed alteration mapping, gives Questcorp the best chances for success from their investment through Riverside in this work.
• Jabali Area – The primary targets are NW-striking structural veins, with 200 m of strike length identified to date and a surface width of 30 m across a series of low-sulfidation epithermal quartz veins. High-grade assays of over 5 g/t Au have been returned from this area. Drilling at Jabali during this phase will focus on two holes: one testing the vein target and one testing the source target. Detailed maps and cross-sections for each target have been prepared ahead of drilling to best define the conceptual targets.

General Overview of La Union Project

The Project is summarized in a recently published NI 43-101 Technical Report and, more briefly, on the Riverside website. Riverside initially acquired the Project and subsequently consolidated additional inlier mineral claims to build a strong land position. The company then advanced the Project through surface access agreements and drill permitting, making it a turnkey exploration opportunity for the Optionee.

The Project was originally identified through Riverside’s exploration work in the western Sonora Gold Belt, conducted in collaboration with AngloGold Ashanti Limited, Centerra Gold Inc., and Hochschild Mining Plc. Earlier PhD research by Riverside founder John-Mark Staude also contributed to recognizing the district’s potential. Initial work by members of the Riverside team, drawing on more than two decades of geological compilation and analysis, further confirmed the region as highly prospective.

At the Project, historical mining by Peñoles targeted chimney and manto-style replacement bodies within the upper oxide zones. As a result, the underlying sulfide zones represent immediate drill targets for further exploration.

The Project features favorable limestone host rocks, an extensive alteration footprint, and multiple small-scale historical workings, with mineralization styles similar to those at the Hermosa Project in southern Arizona. At Hermosa, South32 is advancing mine development after acquiring the project from Arizona Mining for over $400 million, and Hermosa is now considered one of Arizona’s most promising upcoming mining operations.

At La Union, immediate drill targets offer the potential for significant-scale discoveries. The Project is well positioned for near-term exploration results, with targets that include both oxide and deeper sulfide mineralization.

Vancouver, British Columbia–(Newsfile Corp. – May 21, 2026) – Riverside Resources Inc. (TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY0) (“Riverside” or the “Company“), with partner Questcorp, the Company has completed an expanded aeromagnetic drone survey at the La Union Project in Sonora, Mexico. The new data refines the drill targets and improves understanding of district-scale geologic structures. Together with property-wide structural mapping and the high-grade Phase 2 sampling results announced May 5, 2026, this information is being used to finalize drill targets ahead of the fully permitted summer 2026 drill program.

Drill roads and pads are being prepared this week, and arrangements with the drilling contractor are progressing rapidly. The geophysics provides greater conviction in the scale of the potential feeder structures and the robust magnetic sources at depth, supporting both the Carbonate-hosted Replacement Deposit targets and the Sediment-hosted, Carlin-like stratigraphic targets discussed below.

Highlights

• Expanded drone aeromagnetic survey adds 145 flight lines (193 km) plus 55 km divided into 20 tie lines, for 248 km of total drone coverage building on the 2025 baseline dataset all done with 100m line spacing for quality definition.
• Improved imaging of structures beneath post-mineral cover, including the new northwest-trending structures identified by spring 2026 field mapping as a potential ore control creates new drill targets.
• Integrates structural mapping with detailed 1:1,000 geologic field mapping of target areas and district-scale 1:5,000 geologic mapping to characterize interpretations at depth that may be associated with mineralization.
• An Induced Polarization (IP) geophysical survey is planned to commence shortly as a further input into Phase 2 drill targeting with planned 5 IP lines that will be done concurrent with drilling the first targets and sets up for continued drilling in Phase 2.
• Drill roads and pads beginning to be built for upcoming Phase 2 drill program.

“The expanded aeromagnetic survey provides a much clearer view of the La Union Project’s structural framework at depth. Combined with the high-grade sampling results released earlier this month, we now have the data in hand to refine our Phase 2 drill targets with greater conviction,” said John-Mark Staude, President and CEO of Riverside Resources Inc. “The program is progressing well, and our teams are preparing for the launch of drilling in the near term. We are also expanding the drill targets in areas where high-grade gold and base metals were previously mined, and where geophysics can now image potential source targets at depth.”

Survey Overview

The survey was flown with a magnetometer suspended beneath a drone along parallel flight lines, with tie lines flown perpendicular to level the dataset. The expanded grid extends magnetic coverage across the property in all directions relative to the 2025 baseline survey, providing district-wide imaging of structural features and magnetic bodies at depth. The 2025 dataset was a key input into planning the Phase 1 drillholes; the expanded 2026 dataset will allow these structures to be traced more confidently beneath post-mineral cover and build a more complete exploration model for Union.
