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 missed opportunities💰 or unexpected losses.😟 Be ready!👨‍🏫.../2

2) #Uranium explorers drill rock core samples looking for signs of #U3O8 bearing ore.🧐 Rarely do they 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 $NXE's Arrow👇 .../3

3) Visual inspection of core samples is just 1 of many steps taken to see if #uranium is found. 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 each core interval.🗒️.../4

4) After an exploration hole has been drilled & 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

5) Here's the Gamma Log Profile for Fission #Uranium $FCU's drill hole PLS17-METC that confirmed the presence of 108 metres of vertical high-grade ore at an average grade of 8.46% #U3O8.☢️😃 This was the best mineralized hole drilled worldwide for any mined metal in 2018.🥇 .../6

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.🔨 Tables are then published for each drill hole.📑 It can take a few months for assays to be completed.😟 .../7

7) Other data provided may include 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

8) If you want to explore & browse these types of #Uranium exploration data, best bet is to visit the Fission #Uranium website, as they are the only explorer/developer that publishes full data publicly for every hole they've ever drilled.📑 Terrific research resource.📚🧐 .../9

9) To get ahead of the herd🦬 you can use the Scint & Assay tables from hundreds of #Uranium drill holes published by Fission to learn how to estimate #U3O8 % Grades from initial Scint data in news releases🧮 well before actual Assays are released.🤠.../10 fissionuranium.com/projects/tripl…

10) Sometimes #Uranium explorers will use a specially calibrated Downhole Gamma Probe to measure estimated % #U3O8 grades found in a drill hole.🗒️ Gamma readings are directly converted to "Grade % eU3O8" for publication. Often done if there are problems recovering cores.⛏️ ../11

11) Drill seasons for #Uranium explorers & developers are my favourite times of the year😃 full of anticipation & high hopes for #U3O8 mineralized drill cores and new discoveries🤯 that can send a U stock rocketing🚀 or not☹️ as investors try to decipher news.👨‍💻 Good luck!☘️🌈💰
