For some reason the tablet is not showing at the end in front of the shield? The Treasure of Britain icon for here does not show on the map either? I am trying to get Excalibur so I have the other 7 tablets but will need to get the 3 from the Zealots. Any help would be amazing? Thanks 
Hey there @Torchwood92!
I apologize that you aren't seeing the tablet to pick up in Santlach Mine. Is it possible that you may have already picked it up earlier in your playthrough and not realized it?
If you kill the final three zealots, does the tablet appear? If not, I recommend loading a previous save from before you acquired some of the other tablets and going to pick up the Santlache Mine tablet.
Could you also share which platform you are playing on?
