They tend to be big, coming in large to extremely large sizes. They can also be amazingly rich and produce huge amounts of very high-grade ore.
So you think you have an ore deposit? The work has been long and hard, but there are a few drill holes, lots of samples and assays. The data is in a reliable computer and there may be a mine at the end of the tunnel. What is the likelihood of a profitable operation? Can you raise capital for development or exploration?
