M77/549 has been quoted as the ground you want, someone who knows the ground well stated that on a KDR thread and bought into KDR thinking that they owned it, he has done well out of his mistake though.
Read the ann from 17th May 2016, it is full of info.
Outside of MZN and M77/549 have a look into WSA, it'll take a bit of time but you will find some info of their lithium finds but they only have a handful of results at this time, they have completed drilling up north and are now away to drill South Ironcap. If you have read the ann from 17th May you will see how much land MZN has that borders WSA's.
If you are wondering where M77/549 is well here is a picture:
