F3 Uranium reported on 21 October on three completed drill holes east, southeast and south of the Tetra zone at its Patterson Lake North project in Saskatchewan. Hole PLN26-232 contained five separate radioactivity intervals, each 0.5–1.0 metres long. The peak handheld spectrometer reading was 4,400 counts per second at 610.5–611.0 metres depth. The other two completed holes had no readings above 300 cps.

The company cautioned that these are preliminary radiometric readings, cannot be directly converted into uranium grades and await laboratory assays. They therefore do not establish a mineral resource or an economic discovery. F3 said it planned to mobilize a second drill rig to follow up the target.
