Thanks, Bruce! Now, with a little procedure name change and a text 
substitution for the legend - lo and behold! I got my Erzgang (ore vein). 
And not only one, many of them; miner's delight :).

My mine surveys are starting to get really useful now. And now onto point 
symbol redefinition!

Best regards, and Glückauf (or what the caver's greet:),
