Adams Plateau Project

The road accessible Adams Plateau Project is located approximately 100 km north-east of Kamloops, British Columbia. Sediment-hosted polymetallic massive sulfide mineralization (silver, copper, gold, zinc and lead) at Adams Plateau is hosted within the prospective Eagle Bay assemblage. The project has excellent infrastructure including extensive road network from past logging activity, power and rail-lines and services are nearby.

Work in 2025 comprised project-wide soil and rock geochemical surveys (Figure 1). Grid-based soil sampling (5,002 samples) was designed to infill and expand on previous surveys aimed at covering the entirety of the prospective Eagle Bay assemblage across the project. Prospecting and rock sampling (83 samples) was also completed near previously reported high-grade soil and rock anomalies.

Results and highlights from 2025 rock sampling program include:

• Lucky-Elsie: High-grade mineralization at the Lucky-Elsie area is characterized by a northeast-southwest trending 1.5 km zone of massive to semi-massive sulfide lenses, following the main foliation, which dips to the northwest. Grab samples from the trend returned up to 2,310 g/t Ag with 20.0% Pb and 1.7% Zn (J039530) and 1,230 g/t Ag with 20.0% Pb and 5.4% Zn (J039524, Figure 2 and Table 1).

• Spar-Ex: High-grade mineralization at the Spar-Ex area is hosted in siliceous and graphitic phyllites of the Eagle Bay Assemblage with sulfides consisting of pyrite, galena, sphalerite, and chalcopyrite. Semi-massive lenses are localized along folds and are locally thickened to approximately 3 m along a strike length of at least 365 meters. Grab samples from the area returned up to 344 g/t Ag with 11.4% Pb and 9.0% Zn (J039509) and 150 g/t Ag with 8.9% Pb and 2.7% Zn (J039758, Figure 2 and Table 1).

Results and highlights from the 2025 soil geochemical survey include:

• Wad-Second (North): Approximately 2 km north of the WAD-Second showing, a northeast trending Pb-Zn-Cu soil anomaly was defined and underlain by the prospective Johnson Lake Unit of the Eagle Bay assemblage. The 500 m by 1,000 m multi-element anomaly is located on the western limb of the property-scale antiform.

• Wad-Second (East): A second, northeast-southwest trending, approximately 1 km long, Ag-Pb-Zn soil anomaly was defined approximately 1 km east of WAD-Second showing. This soil anomaly is underlain by metamorphic rocks of the Eagle Bay assemblage.

• Mosquito King East: A significant coincident Cu-Pb-Zn soil anomaly was outlined 1 km east of the Mosquito King occurrence, trending approximately north-south. The anomaly is underlain by sedimentary rocks of the Eagle Bay assemblage.

• King Tut East: A significant Pb-Zn soil anomaly with a lesser Ag-Cu anomaly was defined 1 km east of the King Tut occurrence on the contact of sedimentary rocks of the Eagle Bay assemblage and a quartz-feldspar porphyry intrusion. The anomalous zone near the hinge of a significant property-scale, north-south trending antiform.

• Spar: A northeast-southwest trending Ag-Pb-Zn-Cu soil anomaly, approximately 1 km SW of the Spar occurrence was defined. The anomaly is underlain by prospective rocks of the Eagle Bay assemblage. The orthogonal orientation of the anomaly with respect to the underlying stratigraphy suggest a structural control on mineralization rather than stratabound.

Next Steps

These new rock and soil geochemical results together with the extensive historical geochemical database will be used to refine high-priority drill targets. The recently granted 5-year multi-year area-based (‘MYAB’) exploration permit provides the Company authorization to drill test many of the targets across the project area.

Quality Assurance & Quality Control

Rock and soil samples were bagged onsite and delivered to ALS Minerals Laboratories in Kamloops, British Columbia. ALS Kamloops / North Vancouver is certified with ISO/IEC 17025:2017 and ISO 9001:2015 accreditation from the Standards Council of Canada.

Rock samples were prepared (CRU-31, SPL-31 and PUL-31) and then analysed for 48 elements by ICP-MS on a 0.25-gram aliquot using a four-acid digestion (method ME-MS61). Gold was analyzed by fire assay on a 30-gram aliquot with an AA finish (Au-AA23). Overlimit samples (e.g. Ag, Cu, Pb & Zn) were re-analyzed using an ore-grade, four-acid digestion and ICP-AES finish (method ME-OG62).

Soil samples were field dried in a temperature-controlled field tent in camp before being shipped to the ALS lab. The samples were then screened to -180 microns (SCR-41) analysed using an aqua regia digestion followed by an ICP-MS finish (method ME-MS41). Gold was analyzed on a 25-gram aliquot with an ICP-MS finish (Au-ST43).

About Standard Uranium (TSXV: STND,OTC:STTDF)

We find the fuel to power a clean energy future

Standard Uranium is a uranium exploration company and emerging project generator poised for discovery in the world’s richest uranium district. The Company holds interest in over 233,455 acres (94,476 hectares) in the world-class Athabasca Basin in Saskatchewan, Canada. Since its establishment, Standard Uranium has focused on the identification, acquisition, and exploration of Athabasca-style uranium targets with a view to discovery and future development.

Standard Uranium’s Davidson River Project, in the southwest part of the Athabasca Basin, Saskatchewan, comprises ten mineral claims over 30,737 hectares. Davidson River is highly prospective for basement-hosted uranium deposits due to its location along trend from recent high-grade uranium discoveries. However, owing to the large project size with multiple targets, it remains broadly under-tested by drilling. Recent intersections of wide, structurally deformed and strongly altered shear zones provide significant confidence in the exploration model and future success is expected.

Standard Uranium’s eastern Athabasca projects comprise over 42,384 hectares of prospective land holdings. The eastern basin projects are highly prospective for unconformity related and/or basement hosted uranium deposits based on historical uranium occurrences, recently identified geophysical anomalies, and location along trend from several high-grade uranium discoveries.

Standard Uranium’s Sun Dog project, in the northwest part of the Athabasca Basin, Saskatchewan, is comprised of nine mineral claims over 19,603 hectares. The Sun Dog project is highly prospective for basement and unconformity hosted uranium deposits yet remains largely untested by sufficient drilling despite its location proximal to uranium discoveries in the area.

These Programs Support the Advancement of Tonopah West Towards the Permitting of an Exploration Decline to Enable Test Mining and the Extraction of a Bulk Sample

HIGHLIGHTS:

• The Phase 2 hydrology program will consist of placing 5 additional piezometers, a dewatering well and a groundwater monitoring well;
• Geotechnical evaluation is progressing on 22 drillholes along the proposed decline alignment; and
• A seismic program consisting of 18 kilometres in seven lines is planned over the Tonopah West deposit and to the northwest to identify extensions and structural controls.

Blackrock Silver Corp. (TSXV: BRC,OTC:BKRRF) (OTCQX: BKRRF) (FSE: AHZ0) (‘Blackrock’ or the ‘Company’) is pleased to announce certain advancement programs (the ‘Programs’) at the Company’s 100% owned Tonopah West (‘Tonopah West’) project located in Nye and Esmeralda Counties, Nevada, USA. The Programs will consist of a Phase 2 hydrology program, geotechnical evaluation of the proposed decline alignment and a seismic survey intended to understand the structural controls and advance Tonopah West toward completing an exploration decline that will allow for test mining and the extraction of a bulk sample for metallurgical processing.

Andrew Pollard, the Company’s President and Chief Executive Officer, stated: ‘Tonopah West is moving forward on multiple fronts as we work to grow, optimize and de-risk the project toward underground development. The integration of hydrologic, geotechnical and seismic data from these Programs represents key de-risking initiatives, helping us refine engineering models, optimize decline design and establish a strong technical foundation for permitting our initial test mine and bulk sample area. These Programs are running in parallel as we await pending assay results and the delivery of an updated preliminary economic assessment on Tonopah West, currently slated for Q1 2026.’

Hydrology Programs

Montgomery and Associates was contracted to complete the hydrology programs on Tonopah West. In the Phase-1 hydrology program, the Company set four piezometers along the proposed alignment of the decline that have been collecting data that reports where water is present (see May 15, 2025 news release). Based on the information collected from the Phase-1 hydrology program, a Phase-2 hydrology program at Tonopah West has been approved. The Phase-2 program will be entirely within DPB South area of Tonopah West where the Company is planning its exploration decline, test mining and bulk sampling programs. The Phase-2 hydrology program will set five additional piezometers, a dewatering well and a groundwater monitoring well. Data from this infrastructure will help with engineering design of the decline, water pumping requirements and site disposal strategies.

Geotechnical Evaluations

Call & Nicholas, Inc. have been retained to complete geotechnical evaluations on Tonopah West. Detailed geotechnical evaluation on the Phase-1 piezometer holes has been completed. This evaluation is critical for the engineering and design of the proposed exploration decline. An additional 17 drillholes are being geotechnically logged and 36 samples have been collected for geotechnical unconfined compression strength testing. Approximately 59,000 metres (193,570 feet) of core drilling from the project has been evaluated for recovery and Rock Quality Designation (RQD). Additional geotechnical study is being planned.

Seismic Survey

The Company has contracted Bird Seismic Services, Inc. to complete 18 kilometres of 2D seismic data. The seismic data will be collected on seven lines cris-crossing the Tonopah West project area (See Figure 1.). Several lines have been located on the northwestern portion of Tonopah West to identify the extension of the Fraction caldera margin under cover. The goal of the seismic survey program is to better understand the structural controls of the deposit and identify extensions of silver and gold for drill targeting.

Forward-looking statements in this news release relate to, among other things: the Company’s strategic plans; the contents and completion of the Company’s Programs at Tonopah West and the anticipated objectives and results therefrom; the permitting of an exploration decline to enable test mining and the extraction of a bulk sample at Tonopah West; the timing of completion of an updated preliminary economic assessment on Tonopah West; the Company’s de-risking initiatives at Tonopah West; estimates of mineral resource quantities and qualities; estimates of mineralization from drilling; geological information projected from sampling results; and the potential quantities and grades of the target zones.

These forward-looking statements reflect the Company’s current views with respect to future events and are necessarily based upon a number of assumptions that, while considered reasonable by the Company, are inherently subject to significant operational, business, economic and regulatory uncertainties and contingencies. These assumptions include, among other things: conditions in general economic and financial markets; accuracy of assay results; geological interpretations from drilling results; timing and amount of capital expenditures; performance of available laboratory and other related services; future operating costs; the historical basis for current estimates of potential quantities and grades of target zones; the availability of skilled labour and no labour related disruptions at any of the Company’s operations; no unplanned delays or interruptions in scheduled activities; all necessary permits, licenses and regulatory approvals for operations are received in a timely manner; the ability to secure and maintain title and ownership to properties and the surface rights necessary for operations; and the Company’s ability to comply with environmental, health and safety laws. The foregoing list of assumptions is not exhaustive.

The Company cautions the reader that forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements contained in this news release and the Company has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: the timing and content of work programs; results of exploration activities and development of mineral properties; the interpretation and uncertainties of drilling results and other geological data; receipt, maintenance and security of permits and mineral property titles; environmental and other regulatory risks; project costs overruns or unanticipated costs and expenses; availability of funds; failure to delineate potential quantities and grades of the target zones based on historical data; general market and industry conditions; and those factors identified under the caption ‘Risks Factors’ in the Company’s most recent Annual Information Form.

Forward-looking statements are based on the expectations and opinions of the Company’s management on the date the statements are made. The assumptions used in the preparation of such statements, although considered reasonable at the time of preparation, may prove to be imprecise and, as such, readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statements were made. The Company undertakes no obligation to update or revise any forward-looking statements included in this news release if these beliefs, estimates and opinions or other circumstances should change, except as otherwise required by applicable law.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
