”And why would they do that if the geology of the area isn’t one which would lead them to expect minerals.”
Any significant structure would introduce a gravitational and/or magnetic anomaly. Given that, keeping the structures as small as possible seems the way to go, but of course, you also want to contain the waste for thousands of years.
On the other hand, one could hope that anybody who can detect such anomalies knows about radiation, too.
