1) With many #Uranium Explorers now actively drilling in #Canada's #AthabascaBasin⛏️ perhaps it's time⏳ for a thread on how to interpret drill data coming soon🔜 in news releases.📰 Misunderstanding data can lead to premature exit... selling when ya shoulda been buying.🛒 🥴

2) #Uranium explorers drill rock core samples looking for signs of #U3O8 bearing ore.🧐 Rarely do they ever hit high-grade on first few attempts.😟 Geologists first look for visual signs in the core samples... here's description from pre-discovery 2013 drilling at Arrow (Rook 1):

3) Visual inspection of core samples is just 1 of many steps taken to see if they found #uranium. Presence of radioactivity is best indicator so all cores are scanned with an instrument called a Hand-held Scintillometer to produce "Scint" CPS tables for cores from each hole.🌡️

4) After an exploration hole has been drilled & all core samples recovered, an instrument called a Downhole Gamma Probe is lowered to the bottom & recovered, constantly measuring #uranium radioactivity in a 360 degree sweep to produce a complete Gamma Log Profile for each hole.✍️

5) Here's the Gamma Log Profile for Fission #Uranium $FCU's world-record drill hole PLS17-METC that contained a continuous 30-storey tall set of high-grade U core sections, 108m at Average Grade of 8.46% #U3O8. Best mineralized hole drilled worldwide for any mined metal in 2018🏆
