The Curse of Oak Island season 8 is happening on History but the official release date remains uncertain as of this writing. Once the reality series returns, it will continue to follow brothers Marty and Rick Lagina digging for the speculated treasures in Oak Island, in Nova Scotia, Canada.

The Lagina brothers have been fascinated by the mysteries on the island, which is believed to have been holding buried treasures left centuries ago. Now, it looks like they're getting closer to unearthing these valuables in The Curse of Oak Island season 8.

In season 7, Marty and Rick were thrilled with their digging as it showed positive signs that there's something buried deep down the island. The two and their team uncovered woods, metal sheets, and tools that may have been used to build tunnels leading to the so-called Money Pit.

They also believe that the big chunk of woods came from booby traps in order to keep treasure hunters away from digging the valuables. The hunt for the treasures has been, reportedly, going for over 200 years and none of the explorers and treasure hunters have found them until now.

There are a lot of theories as to who buried the treasure in Oak Island. One of the most popular is that it was left by Captain Kidd, a Scottish sailor. Others suggest the valuables were from a sunken ship which is believed to be owned by pirates.

These theories don't only offer the location of the treasure, but also its history. The latest expedition of Marty and Rick in The Curse of Oak Island season 8 could change the history since they're looking for artifacts that are seemingly holding a different story than what was recorded in books.

The Lagina brothers might be finally getting closer to digging the Money Pit, as they'll use a new strategy to dig deeper into the ground. In the final episode of season 7, the team all agreed that they won't be using cans anymore. Instead, they'll proceed with the project "Big Dig."

This would be the major project of Marty and Rick in The Curse of Oak Island season 8. Their previous attempts using can only reach a certain distance. Now, they wanted to dig farther than 50 feet deep down as they believed the Money Pit was moved far down due to floods and other natural causes.

Meanwhile, History hasn't officially renewed The Curse of Oak Island season 8. But, there is a strong indication that the reality series will push through. Reportedly, there's a sign of filming on the island as early as June, and the residents in the area have been seeing equipment, trucks, and filming crews.
