Cautionary Note Concerning Disclosure of Mineral Resources: The NI 43-101 and S-K 1300 reports (for each of the Lost Creek Property and Shirley Basin Project) that are linked above on this webpage are substantially the same except for internal references to the regulations under which the report is made, and certain organizational differences. As we are required to do, the mineral resource estimates included the “S-K 1300” reports linked on this webpage and other references to mineral resource estimates on our website have been prepared in accordance with U.S. securities laws pursuant to Regulation S-K, Subpart 1300 (“S-K 1300”). Prior to these estimates, we prepared our estimates of mineral resources in accord with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves (“CIM Definition Standards”). NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for public disclosure an issuer makes of scientific and technical information concerning mineral projects. We are required by applicable Canadian Securities Administrators to prepare and file in Canada an NI 43‑101 compliant report when we file an S-K 1300 technical report summary.
