[Help] Changing The Goldmine Mini Map Icon

So yeah, I have roughly 196 gold mines on my map in a fairly small space, they're fairly clustered.

I'd like to change the goldmine icon to something fairly small so that the map is more visible yet I want them to still be prevalent.

Hm, so does anyone have any ideas on how to change this? I've tried several things but they didn't seem to work.

Minimap icons have fixed size, soo you cant make them lesser.

I know how to change the icon size, just not how to change the icon.

If I recall correctly, it uses a TGA file. Couldn't I just alpha the background to make it think it's a 64x64 but only use say... 16x16?

16*16 ALWAYS 16*16 you cant make it lesser.

In that case I'll make it 8x8 with an alpha-removed surrounding.
