JERUSALEM, Jan 8 (Reuters) -
* Israel’s Delek Group said on Monday it has signed a deal with GulfSlope Energy and Texas South Energy to explore 12 concessions in the Gulf of Mexico.
* Delek, through a foreign subsidiary, agreed to cover 90 percent of the costs for the first two drill sites - up to $50 million - in exchange for 75 percent of the rights in those prospective drilling sites at the first stage.
* Delek said it will use its own funds for the project and will have the option to buy rights in the other concessions as well.
* A third-party resource report showed a first stage best estimate of 99 million barrels of oil and 177 billion cubic feet of natural gas, Delek said. (Reporting by Ari Rabinovitch; Editing by Steven Scheer)
