There are two types of ancient remains: Ancient remains, which require the t1 phosphate mine unlocked at logi science, and big ancient remains which require the t2 phosphate drill unlocked at chemical science. Currently, these both show up as "Phosphate Rock" on the map, and there's nothing to suggest that each tier needs a different type of drill.
I'd suggest:
Making the big ancient remains labelled "Big phosphate rock" on the map
Adding "Requires a <phosphate mine/big phosphate mine> to mine" to the tooltips of the ore patches
(possibly) Adding "Can mine <phosphate rock/big phosphate rock>" to the tooltips of the drills.
