Speed Goat Phase II Drill Results

Scout has successfully completed a 2,000-meter, 6-hole core drilling program at its Speed Goat porphyry Au-Cu (Ag) project in Nevada. This Phase II program follows up on initial successful drilling conducted in 2022 by the team during their tenure at EMX Royalty Corp. (“EMX”), prior to spinning out as Scout. That work intercepted robust porphyry Au-Cu-Ag mineralization beginning at surface – significant results are outlined above in the summary section, and in Table 1.

The Speed Goat project is located within the prolific Battle Mountain mining region of north-central Nevada (Figure 1). This district hosts multiple producing gold (Marigold, SSR Mining) and gold-copper mines (Phoenix Complex, Nevada Gold Mines). The project was initially identified and acquired through staking by the Scout team, formerly as EMX employees, in 2021.

Historical exploration is uncertain; however, previous drilling and exploration work is reported to have taken place in the mid-1990s between Pittston Nevada Gold Co. and Newmont Mining Corp. To date, Scout has relied solely on its own drill results to guide its exploration efforts. The outcropping mineralization at Speed Goat, combined with strong reconnaissance geochemistry, proved compelling even without historic drill data available in 2022, prompting the completion of an initial 862-meter Phase I core program. Notable intercepts from Phase I, beginning at surface, included 284.0m @ 0.34 g/t Au, 1.87 g/t Ag, and 0.10% Cu (0.46 g/t AuEQ or 0.43% CuEQ; with a higher-grade interval of 16.9 meters at 0.76 g/t Au, 1.24 g/t Ag, and 0.20% Cu (0.96 g/t AuEQ or 0.82% CuEQ.

The Phase II program outlined here was designed to test previously drilled holes, both at depth and along strike, to better understand the scale potential. Strong porphyry Au-Cu-Ag mineralization was intercepted in all step-outs, indicating significant tonnage potential starting at surface.

Geologic Mapping: During 2025, the Scout technical team remapped the Speed Goat project area using digital “Anaconda-style” outcrop mapping to document lithology, structure, alteration, and mineralization in detail (Figure 2). The primary goal was to assess the time-space relationships between the host Jurassic igneous units, the later Eocene (?) mineralized porphyry dikes, and the outcropping mineralization, in order to better understand the tonnage potential. Figure 3 displays results of this work, which shows widespread early potassic and later sericitic alteration, with zones of >10 quartz-pyrrhotite-chalcopyrite veins per meter documented across an ~1 square kilometer area associated with a series of porphyry dikes. Several high-priority new targets were identified, particularly when considered in context with insights gained during this latest drill program (Figure 4 and Figure 5). Figure 6 through Figure 9 are drill sections of Holes SG25-04 to 06 displaying Au and Cu grades. Refer to the following links for drill sections of Ag for Holes SG25-04, SG25-05 and SG25-06.

SG25-06: The Phase II drill program successfully extended mineralization both along strike and at depth, while also identifying a higher-grade Au-Cu-Ag zone that warrants follow-up. Hole SG25-06 was the last and most significant of this program, which drilled beneath the best channel samples. The entire 357.5m hole assayed 0.35 g/t Au, 0.11% Cu, 1.66 g/t Ag (0.46 g/t AuEQ; 0.52% CuEQ). This included a higher-grade interval of 38.9m (from 149.2-188.1m) @ 1.02 g/t Au, 0.27% Cu, 2.25 g/t Ag (1.29 g/t AuEQ; 1.44% CuEQ) within 164.8m (from 23.23-188.1m) @ 0.51 g/t Au, 0.15% Cu, 1.98 g/t Ag (0.67 g/t AuEQ; 0.75% CuEQ). The hole ended in strong mineralization and was terminated at the Nevada Gold Mines property boundary to the northeast.

Figure 8: Drill Section for SG25-04 Showing Au Grades in Core

Figure 9: Drill Section for SG25-04 Showing Cu Grades in Core

SG25-04 and 05: Both holes demonstrated that Au-Cu-Ag grades are largely continuous across ~400m of outcropping mineralization. SG25-04 was drilled at -60 degrees beneath the previous hole SG-22-02 (-45 degrees). This hole successfully showed vertical continuity of mineralization over the 483m hole length (~420m true depth), without exiting potassic alteration or mineralized Au-Cu-Ag veins. The hole was terminated because vein dips had shallowed and the inclination had steepened moderately to where the hole was nearly parallel to the quartz vein sets, making it no longer representative. There remains potential to expand mineralization beyond 420m with different hole orientations beneath SG25-04 and steeper drilling beneath SG25-06.

SG25-01 to 03: The Company drilled three holes from one drill pad to test for southeast extensions of the porphyry Au-Cu-Ag system under post-mineral gravel cover in the hanging wall of a post-mineral fault. Bedrock was encountered ~25 meters below gravel, with all holes intercepting strong zones of porphyry-style sericitic alteration and local zones of >0.5 g/t Au up to 1.23 g/t Au over 0.94m and 0.05% Cu over 0.81m. These results suggest upper portions of a porphyry system are preserved, and the pediment area holds potential for additional porphyry Au-Cu-Ag mineralization. Further drilling will be necessary to vector into higher-temperature and potentially higher-grade zones of the porphyry system(s) in the pediment. Refer to the following link for drill sections of SG25-01 to 03 showing Au, Cu and Ag grades in core.

Figure 10: Core photos from SG25-04, 05, and 06 highlighting key porphyry mineralization styles and associated grades with sheeted to stockwork quartz-pyrrhotite-chalcopyrite veins cutting Jurassic quartz monzonite.

Economic Potential and Next Steps: Vein mineralization at Speed Goat is primarily pyrrhotite-chalcopyrite with minor molybdenite in potassic alteration, and later pyrite-dominant mineralization associated with sericitic alteration. This is directly analogous to intrusion-hosted Eocene porphyry mineralization at similar Au-Cu-Ag grades, processed at the Phoenix Mining Complex, ~25km southeast, using standard gravity, flotation, and carbon-in-leach methods. Although metallurgical work at Speed Goat has not yet been completed, the simple sulfide composition and uniform geology suggest a straightforward processing approach.

The Speed Goat project lies within Nevada’s “checkerboard” land, where alternating one-mile by one-mile sections are either BLM or private land, largely owned by Nevada Gold Mines. Thanks to its fortuitous surface and mineral rights history, Speed Goat connects with BLM land over two sections (Figure 1), forming a contiguous land position containing >95% of the known outcropping Au-Cu-Ag mineralization. The site offers easy road access, favorable topography for open-pit mining, and high-voltage power lines across the project in a major mining region. These advantages position Speed Goat for aggressive advancement to demonstrate significant scale and grade potential for porphyry Au-Cu-Ag mineralization.

Exploration and Permitting Updates

Scout is advancing earlier-stage projects and generating near-term cash flow through drilling while awaiting final U.S. Forest Service permits for a 10,000-meter drill program at the Cuddy Mountain project, expected still for 2025. Upon receipt of the permits, the Company plans to mobilize drill rigs to Cuddy Mountain for the 12-month permit period, including drilling at the Railroad targets located on private land.

As part of a collaborative initiative, Scout and Hercules Metals completed a 120 km² district-scale MT–NSIP geophysical survey across the Cuddy Mountain and Hercules properties. The survey was conducted by Moombarriga Geoscience, a global leader in deep-sensing geophysical methods. Scout helped Moombarriga expand to the U.S.A. in 2024 when the firm completed a 3D-IP survey at Cuddy Mountain. This MT-NSIP survey enables structural interpretation to depths of up to six kilometers — an order of magnitude deeper than previous techniques — and is expected to significantly enhance targeting and porphyry discovery potential across the region.

Scout’s in-house exploration team is now focused on advancing gold and copper targets across its Idaho portfolio — including the Muldoon, Independence, Moose Ridge, and Century projects — toward drill-ready status for 2026 and beyond.

External Revenue Generating Contracts

Scout expanded from two to four surface core drills through three new contracts via its wholly owned drilling division, Scout Drilling LLC. Current operations include two rigs at Hercules Metals, one at IDEX Metals, and a fourth in western Nevada with Wolfden Resources. The agreements with IDEX and Wolfden include TerraCore hyperspectral imaging (see May 9, 2024 news release). Scout is also overseeing program management, core logging and cutting for Wolfden. These contracts strengthen Scout’s financial profile position as a major cash-flow-generative operator. They also highlight increasing demand for its integrated drilling and technical services, supporting continued advancement of its internal exploration portfolio without significant shareholder dilution.

Building Long-Term Value with a Vertically Integrated Model

Scout’s unique positioning as a vertically integrated exploration and drilling company with the ability to offer technical services, enables long-term value creation (Figure 11):

Cash Flow Generation – Three active drilling contracts with four drills provide steady cash flow into 2026.

Exploration Leverage – Ongoing cash flow allows Scout to advance its own projects independently of equity markets, reducing shareholder dilution.

Technical Depth – Stable finances support a robust internal technical team for advancing drilling and exploration programs for Scout and partners.

Strategic Visibility – Partnerships with Hercules Metals, IDEX Metals, and Wolfden Resources enhances Scout’s profile and provide insight on emerging mineral belts.

Figure 11: Scout Discoveries Vertically Integrated Model Venn Diagram

With a sustained balance of external contracts providing significant cash flow generation and a project pipeline moving towards discovery with compelling porphyry Au-Cu-Ag drill results at Speed Goat, Scout is well-positioned to deliver meaningful catalysts with a strong balance sheet in the second half of 2025 and beyond.

Curtis Johnson, President & CEO commented: “We are highly encouraged by the results to date at Speed Goat and will continue to advance the project as a key goal of the Company, in conjunction with Cuddy Mountain and other high priority targets in our portfolio. First and foremost, Scout is a discovery-focused company and will always be so – as genuine economic discovery is what drives value creation in this industry. In pursuit of this, Scout’s vision is to transform exploration by bringing the discovery process in-house — reducing costs, increasing efficiency, and building a sustainable, profitable business. Our goal is to combine external contracts as described here with discovery upside on our portfolio through earn-in joint venture agreements – whereby Scout is both the underlying project owner and technical services provider. This is a fully aligned partnership structure where Scout provides drilling and technical services at lower cost to earn-in partners, while profitably advancing our large portfolio through discovery. The more efficient we are in advancing our projects for partners, the more work is done per dollar and the better odds we have of discovery. We are motivated to demonstrate this model and continue to advance partnership discussions with multiple parties across our portfolio.”
