Magma chamber. Is this a problem?Apparently there is a magma chamber directly underneath the graphine deposit. According to ZEN, the graphine vein is a vertical 1km. My question is how far down can they dig before creating a risk of the magma chamber pushing up through the upper crust in that area? They keep conducting more university research on graphine applications with little visible effort in actual setting up the preliminary infrastructure for a mining operation which has me concerned that there may be serious engineering concerns on how to actually mine this stuff to a respectable level without drowning a few northern Ontario folk in a lava flow. I'm not a geologist so maybe someone more knowledgable on the topic can comment.
