Bit late but if anyone else needs this you can add it on your own fairly easily. Unzip the mod in your mods folder, then you can remove the zip file (a folder should exist in the same position with the same name now). In there you can edit data-final-fixes.lua . There are three lines to specifically add fissures from Angel's mods. YOu can add support for mineral water the same way, just copy those three lines and replace angels-fissure with mineral-water, so the code should look like this:
-- Add Angel's Fissure
if data.raw["resource"]["angels-fissure"] then
resource_entities[#resource_entities + 1] = "angels-fissure"
end
if data.raw["resource"]["mineral-water"] then
resource_entities[#resource_entities + 1] = "mineral-water"
end
Then save and restart factorio.
