Take help of AP CM for this treasure. He will arrange all possible machinery if you sure its 100% underground treasury in just 30M depth. They may dig even if its available in 100Mtrs deep. Such money will helpful to rebuild the State and you also would be rewarded with honor.

PS: No one has powers to do magic to uplift underground/unseen/unknown treasury. Its true. If they have such powers, they could lift many historical known hidden treasuries and help the mankind.
