Noble Plains Uranium Corp Announces Maiden Mineral Resource Estimate for Duck Creek Project Noble Plains Uranium Corp. has announced a maiden mineral resource estimate prepared in accordance with National Instrument 43-101 standards for its Duck Creek Project in Wyoming's Powder River Basin. The estimate, prepared by WWC Engineering of Sheridan, Wyoming, follows the Company's successful drilling campaign and represents a foundational milestone for Noble Plains. Furthermore, an Exploration Target for the Project is estimated at between 941 and 1,021 thousand tons grading between 0.020% and 0.052% U3O8. The Exploration Target was prepared by WWC Engineering and is based on historical Kerr-McGee drill hole intercept data and trend mapping covering approximately 2.75 miles of mineralized strike on the Company's expanded claim position that lies outside of, and along strike from, the area covered by the maiden mineral resource estimate. The lower and upper limits of the tonnage and grade ranges were derived by applying the GT Sum Contour Method to the historical intercept dataset, using the same parameters adopted for the maiden resource estimate: a grade cutoff of 0.020% eU3O8, a GT cutoff of 0.20, and a one-foot minimum intercept thickness, with tonnage calculated using a bulk density of 16.6 ft3/ton. The Exploration Target relates exclusively to the Wasatch Formation and does not include any potential of the underlying Fort Union Formation. The potential quantity and grade of the Exploration Target is conceptual in nature as exploration in these areas is insufficient to estimate a mineral resource. It is uncertain if further exploration will result in the Exploration Target being delineated as a mineral resource. Canadian Institute of Mining Metallurgy and Petroleum ("CIM") Definition Standards require an assessment of the historical and recent data used to classify resources at Duck Creek. This analysis demonstrated that both the historical and recent data, as well as their interpretation, were developed by
reputable and experienced uranium exploration companies with appropriately qualified staff experienced in uranium exploration. Available data from historical drilling and exploration included drilling maps and intercept data sheets. Historical mineral trend maps were cross-checked against intercept data sheets. Ten percent of the tabulated mineral intercept values were reviewed and found to be valid. Recent exploration includes a 148-hole exploration drilling project completed by Noble Plains. Both historical and recent data were used to complete the mineral resource estimate and the recent drilling data were also used to verify the historical data. Numerous holes were drilled in 2025 that were very close in proximity to historical drill holes. The recent drilling not only followed the same trends as the historical drilling, but also produced mineral intercept data similar in depth, thickness, and grade, thereby validating the historical results. The QP has adequately verified the historical and recent data for the Duck Creek Project. The QP has reviewed the data validation process and finds the drillhole database to be sufficient and adequate for resource estimation. The QP concludes the work done by Noble Plains to verify the historical data has validated the Project information used to calculate the resource estimate. New Risk • Apr 05
New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of Canadian stocks, typically moving 19% a week. This is considered a major risk. Share price volatility increases the risk of potential losses in the short-term as the stock tends to have larger drops in price more frequently than other stocks. It may also indicate the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (19% average weekly change). Earnings have declined by 3.7% per year over the past 5 years. Shareholders have been substantially diluted in the past year (41% increase in shares outstanding). Revenue is less than US$1m. Market cap is less than US$10m (CA$9.73m market cap, or US$6.98m).
