a SONDAGEM que revelou ROCHA INCRÍVEL!

Talk to me next door! ---- https://prospectbrasil.com/links-davi/ We discovered rare stones at great depth! We drilled into the ground and look what's there! An incredible rock, a very valuable marble hidden deep underground! That's right, we did diamond rotary drilling in a mineral exploration for marble! The famous black marble, or Nero Marquina! My team and I had already developed some mineral exploration activities in this same area, such as geophysics and geological mapping... but this time we reached the final stage! Drilling boreholes! Rotary drilling aims to bring rock cores to the surface, showing what the material is like down there at depth! Curious, isn't it? And this drilling and mineral exploration activity is the most important for the research of any ore, whether it's gold ore, iron ore, copper, or other different and valuable metals! It's even used to research precious stones! So, are you curious to see more of this geology activity in the field? See you in the video! ⛏ Follow me on Instagram! 👉 @davi_madureira ⛏ Did you like it? 🤙 Subscribe! -------------------------------------------------------------------------------
