Check your PMs, I replied.
There is an instrucitons.txt included with the mod -- read that.
there is also directions the download page at RTB -- read that.
there is a 'save all ores' button -- make sure you use that.
check your console for errors
check config/server/MiningData.cs to see if your ore is there - it should be at the end
make sure you have mining mode turned on
make sure you are the host.
if its in the file, but now showing up in the map, then check the min/max percent and the depth.
set min depth =0 to make it spawn anywhere.
