One full page for minerals, one page plus four for minerals and two geysers. Two lines with workers plus two for gold, two lines plus six with geysers.
3 workers per patch is fully saturated and with 8 mineral patches in a normal base 24 or 3 lines of workers is fully saturated. 6 more for 2 geysers, but you will only select 4 of them at a time so ctrl clicking on your base one page plus 4 should be fully saturated. 18 for gold (6 patches) without minerals and 24 for gold with 2 geysers.
HOWEVER, 2 bases with 12 workers mine more than 1 with 24, a fully saturated base isn't a perfect base..
Pretty sure this is the same for all races.
