According to online. '0.33 U uranium mine," the number 0.33% U refers to the uranium grade, or concentration, within an orebody. This figure is significant because it is a relatively high grade for uranium and has been referenced in relation to at least two different mining projects.
Two different mining projects have referenced a 0.33% uranium grade:
Four Mile Mine, Australia: An estimate from November 2013 for this project in South Australia showed a mineral resource of 9.8 million tonnes at 0.33% U3O8 (the chemical formula for triuranium octoxide).Drake Lake-Silas Project, Canada: In a November 2025 announcement, Power Metal Resources reported drilling results from this project, revealing a uranium grade of 0.33% U over 2.05 meters.
