I think that Cinder told them about it (without getting into much detail about their power and origin) so they cold look for it while she took the Maiden powers and destroyed Beacon tower.

I believe that the reason Salem is having trouble finding the Relic is not because it is well hidden in Beacon or because it is Ozpin's cane, but because the White Fang found it first, and are just waiting for the chance to use it.
