OpenGL procedural terrain.
Here is a smalll list of some of the techniques I used here:
. tessellation shaders
. trilinear texture mapping
. 2D billboards
. displacement mapping
. wind animation using noise texture
. HDR
. advanced bloom via downsampling
 

Improved bloom + experiments with adaptive exposure.

Bloom is heavily inspired by the method described by Jorge Jimenez in his great slides here: http://www.iryoku.com/next-generation-post-processing-in-call-of-duty-advanced-warfare (starts from slide 144)

It depends on what you want from the ore distribution, but I can't think of any particular reason why you can't use a noise map for ores given that you are using one for terrain.
