There's no such thing as lightly Earth-aspected mana; it either is or it isn't. This means that, while she could maybe find places to stick stray bits of Earth mana into a spell without the whole spell collapsing, it's then clearly a tiny bit of Earth mana laid over a lot of unaspected mana. You straightforwardly couldn't make a version of a Golarion spell entirely out of Earth mana without redesigning that entire spell from scratch, and even then, you just would not expect to find any way for Earth mana to move in those subtle and complicated ways. Casting Detect Thoughts this way seems legitimately as far out of reach as the local sun.
She can probably get something like a spike of hardness jabbing at somebody, but not as powerfully as, like, poking them hard with your finger. There's definitely going to be some way to take a big mass of this mana and condense it to where it becomes a tangible supersolid that can then be accelerated and flung beyond her control, but it feels like she's missing some primitives from the library of laws she'd need to exploit.
