Treasure hunters are on the verge of discovering what they call the “world’s largest treasure hoard.”

The Temple Twelve team has searched for the “Lemminkainen Hoard,” which comprises of gold, jewels, and antiques since 1987. They believe spades, buckets and other rudimentary instruments helped them reach the hoard in Finland, estimated to be worth more than $20 billion.

They claim to be just a dozen feet away from finishing excavation, which is expected to end in the summer of 2022. Fifty-thousand gemstones, including rubies, sapphires, emeralds, and diamonds are in the vast trove according to the New York Post. There are also expected to be 1,000 artifacts dating back thousands of years, and a handful of 18-carat gold life sized statues.

The hoard is in a Sipoo underground temple within the Sibbosberg cave system, about 20 miles east of Helsinki.

“Significant progress at the temple has been made, and … the crew are feeling especially excited about the months ahead,” Lemminkainen Hoard expert Carl Borgen, 60, said according to the paper.

“Temple Twelve, as they have become known, have been able to remove several huge square granite rocks blocking the entrance to the cave, and have cleared the cave of hundreds of tonnes of smaller rocks and sediment,” he added according to the Good News Network.

In 1984, landowner Ior Bock announced he was descended from Lemminkäinen, a Finnish mythological hero. Bock claimed stone slabs were used to sealed-up the treasure back in the 10th Century to protect it from intruders. His former assistants allegedly killed him in 2010.
