Use different colour for each prospected tile, depending of what you find while prospecting.
For exempleexample, paint in grey the tile for wich which it says "The There is iron ore nearby" when you prospect. In maroon the tile for wich which it says "The There is only rock here". Paint the grass tile in green, and the water in blue. After you prospected every rock tile, you should get something like that :http://img367.imageshack.us/img367/4126/before8dn.jpg

== Eliminating the tile where there isn't vein ==
Paint all the rock tile that are in a 7x7 square around the maroon tiles in black.
Mine on the "grey tile"! If it say that the rock is too hard to mine, then mine the tile at the right or a at the left.
== Others exemples examples ==This is the map of the rock tiles near my house, and that's '''exactly''' how i I found the iron vein. They were exactly where i I found them on the map.
