I have not seen this before. In the game I am playing right now that I just started, the ores don't appear on the minimap.

You can see below:

There is a bug in version 0.7.2 which causes minimap not showing correctly (missing trees, ores, bietrs and biter bases, your own structures, etc.).
If I'm not mistaken the developers sad it will be fixed in version 0.7.3.

Yes, this is fixed for 0.7.3, that should be released today.
