Scientists Just Made a Real Treasure Map for Metals Hidden in Earth!

Scientists discovered that rare metals used in phones and electric cars hide in special volcanic rocks found deep under old continents. By studying thousands of rock samples and pictures of Earth's insides [using sound waves to see underground], they created a giant map showing where these metal treasures are buried. Now we might be able to find these materials much faster — it's like having an X-marks-the-spot map for real!
