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 you 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 downhole Gamma Log Profile for Fission #Uranium '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. 🏆

6) Boxes of #uranium cores are then shipped off to a lab where they are assayed to determine exact % Grade #U3O8 (& other minerals like #Gold) in 1/2 metre intervals. This leads to a month or 2 of waiting by investors to see actual grades. Tables are then published for each hole.

7) Other data often provided includes Maps & overlays of surface and airborne survey data, or perhaps most valuable are Cross Section Views that show angles of drill holes along a survey line & geologic interpretation around the #uranium bearing ore, used to build 3D models.🧩

8) If you want to explore & browse these types of #Uranium exploration data, best bet is to visit Fission #Uranium 's website, as they are only explorer/developer that publishes full data publicly for every hole drilled. No cherry-picking as others do.🍒

9) To get ahead of the herd 🦬 you can use Scint & Assay tables for hundreds of #Uranium drill holes published by Fission to learn to estimate #U3O8 Grades from initial Scint data in news releases before associated Assays are released weeks later. 👍 fissionuranium.com/project/triple…

10) Some #Uranium Explorers don't want to wait weeks or months for lab to Assay their cores so you sometimes will see "Grade % eU3O8" published. In this case, downhole Gamma probe is specially calibrated to convert its Gamma Log Profile directly into equivalent % Grade #U3O8. ⛏️
