Standard Uranium Provides Drilling Update on the 2026 Drill Program At Flagship Davidson River Project Standard Uranium Ltd. announced drilling on June 1, 2026, and a total of 900 metres have been completed to date in two in-progress holes on the Bronco and Thunderbird corridors. The first drill hole of the program, DR-26-040, on the Bronco corridor has intersected a total of three metres of anomalous radioactivity (>300 counts per second) with peaks up to 540, 780, and 1,650 counts per second from 464.0 to 466.0 metres. Both ongoing drill holes have intersected strongly graphitic basement structures associated with increased hydrothermal alteration including hematite and clay. Intervals of anomalous radioactivity intersected in hole DR-26-040 are associated with brittle reactivated structures along the Bronco corridor. Drilling is ongoing and is planned to continue through August 2026. The summer drill campaign is targeting basement-hosted, high-grade uranium mineralization on the same regional structural trends that host significant uranium deposits including NexGen Energy’s Arrow deposit and Paladin Energy’s Triple R deposit. Drill targets prioritized and locked-in across three of the four major conductor corridors at Davidson River – Warrior, Bronco, and Thunderbird – based on the integration of the first-ever ExoSphere Multiphysics surveys completed in the southwest Athabasca Basin region. Drills hitting intended meterage with two drill rigs deployed 24/7 to maximize metres drilled and accelerate the testing of the Company’s highest-confidence targets ever generated on the property. Davidson River includes 10 contiguous mineral dispositions totaling 30,737 hectares and lies approximately 25 km west of the Arrow and Triple R uranium deposits and 75 km south of the past-producing Cluff Lake uranium mine. The Company has completed 16,561 metres of diamond drilling in 39 drill holes on the Davidson River property since 2020, which has further refined the exploration strategy for high-grade basement hosted uranium mineralization on the property. The flagship property hosts more than 70 km of conductive trends across four main structural corridors – the Warrior, Bronco, Thunderbird, and Saint trends. All four geophysical corridors contain multiple target areas favorable for high-grade basement hosted uranium mineralization. Geochemical assays are pending. Samples collected for analysis were sent to SRC Geoanalytical Laboratories in Saskatoon, Saskatchewan for preparation, processing, and ICP-MS or ICP-OES multi-element analysis using total and partial digestion and boron by fusion. SRC is an ISO/IEC 17025:2005 and Standards Council of Canada certified analytical laboratory. Blanks, standard reference materials, and repeats were inserted into the sample stream at regular intervals in accordance with Standard Uranium’s quality assurance/quality control protocols. All sample results will be subject to internal quality assurance/quality control protocols prior to subsequent release. Natural gamma radiation from rocks reported in this news release was measured in counts per second using a handheld RS-125 super-spectrometer and RS-120 super-scintillometer. Readers are cautioned that scintillometer readings are not uniformly or directly related to uranium grades of the rock sample measured and should be treated only as a preliminary indication of the presence of radioactive minerals. Because the orientation of mineralization is unknown, true widths are unknown and reported intervals represent core lengths. The RS-125 and RS-120 units supplied by Radiation Solutions Inc. have been calibrated on specially designed Test Pads by RSI. Standard Uranium maintains an internal quality assurance/quality control procedure for calibration and calculation of drift in radioactivity readings through three test pads containing known concentrations of radioactive minerals. Internal test pad radioactivity readings are known and regularly compared to readings measured by the handheld scintillometers for quality assurance/quality control purposes. Historical data disclosed in this news release relating to sampling results from previous operators are historical in nature. Neither the Company nor a qualified person has yet verified this data and therefore investors should not place undue reliance on such data. The Company’s future exploration work may include verification of the data. The Company considers historical results to be relevant as an exploration guide and to assess the mineralization as well as economic potential of exploration projects. Any historical grab samples disclosed are selected samples and may not represent true underlying mineralization. Using a handheld RS-125 Super-Spectrometer, readings exceeding 300 counts per second are considered "anomalous," while those exceeding 65,535 counts per second are considered "off-scale." The Company defines uranium concentrations greater than 1.0 wt.% as "high-grade." Natural gamma radiation reported in this news release was measured in counts per second using a handheld RS-125 super-spectrometer. Readers are cautioned that handheld scintillometer/spectrometer and/or gamma probe readings are not uniformly or directly related to uranium grades of the rock sample measured and should be treated only as a preliminary indication of the presence of radioactive minerals. The Company cautions that results or discoveries on properties in proximity to the Company’s properties may not necessarily be indicative of the presence of mineralization on the Company’s properties.

Standard Uranium Ltd. announced that it expects to receive CAD 4 million in funding Standard Uranium Ltd. announced a non-brokered private placement to issue 40,000,00 units at an issue price of CAD 0.10 per units at an issue price of CAD 4,000,000 on May 26, 2026. Each Unit will consist of one common share of the Company (each a “Unit Share”) and one-half of one common share purchase warrant (each whole warrant, a “Warrant”). Each whole Warrant shall entitle the holder to purchase one common share of the Company (each, a “Warrant Share”) at a price of CAD 0.15 at any time on or before that date which is thirty-six (36) months after the closing date of the Offering. The Offering is subject to certain closing conditions including, but not limited to, the receipt of all necessary approvals including the conditional listing approval of the TSXV and the applicable securities regulatory authorities. The Offering is being made by way of private placement in Canada, in the United States pursuant to an exemption from the registration requirements of the United States Securities Act of 1933, as amended, and in such other jurisdictions as may be determined by the Company. The Offered Securities issued under the Offering will be subject to a hold period expiring four months and one day from the closing date of the Offering. The Company anticipates paying finders’ fees to eligible parties who have assisted in introducing subscribers to the Offering. Any finder’s fees payable will be in accordance with the policies of the TSXV. Announcement • May 20
Standard Uranium Ltd. announced that it has received CAD 0.9 million in funding On May 19, 2026, Standard Uranium Ltd. closed the transaction. The company issued 9,000,000 units at a price of CAD 0.10 for gross proceeds of CAD 900,000. Each Unit consists of one common share of the Company and one-half of one common share purchase warrant. Each Warrant will entitle the holder to acquire an additional common share of the Company at a price of CAD 0.15, commencing on the 61st day after the closing date of the Offering (the “Closing Date”) until 36 months from Closing date. In connection with closing of the Offering, the Company paid a finder’s fee of CAD 54,000 and issued 540,000 non-transferable share purchase warrants (each, a “Finders’ Warrant”) to an arm’s-length party who assisted in introducing subscribers to the Offering.
