Survival - Resource Exploit

I believe I've found an exploit in mining techniques which effectively makes any planetary resource practically infinite.

This started as an art project under ground, (first two shots) I found 3 resources really close to each other, and the intent was to mine them out, and then spectator cam a bunch of screen shots showing off the veins.

I got a little suspicious when the iron started going on for a long time (next 2 screen shots). Then I got really suspicious when the ore started drilling through Ice (next 2 screenshots). Then I passed some rock, and thought that was weird (next screenshot). Then I hit a hard rock surface, and drilled up till daylight,mere meters from the surface (next screenshot). Checking out what was up there, this is what I find (next screenshot). I repeated the process with the nearby nickel I found.

Essentially, on voxel deformation, the blend engine takes nearby textures to inform its own. If you can get just the right amount of deformation above a texture, you can literally carry it anywhere, until you hit ? Surface maps as a easy programming shortcut? I don't know. Anyway, if this process is extended and harvested, where by a resource is pre-mined using this method (oh, all right-click mode on the second drill if it matters), and only harvested from some shape defined for drilling. Did you guys already find this? cause it kind of seems like it should have been discovered by now.
