Tisdale Resources Corp. announced the completion of the 2021 geophysical investigation at Keefe Lake uranium project, in the Athabasca Basin. In all, 3.1 line kilometers of an Induced Polarization (IP) survey were conducted with 100m spacing. The objective of the survey was to investigate subsurface features and anomalies, first identified through diamond drilling and which terminated in highly silicified rocks concurrent with anomalous uranium. The company is in the process of analyzing the data. A full interpretation is expected in the near term. The Company will provide further updates on the survey work as they become available.
