The application also included a proposed timetable for drilling of the Ma'anit-Rehoboth # 2 well.

Zion's application is subject to the review and approval of the Israel Petroleum Commissioner, in consultation with the Petroleum Council. Representatives of the company have already had preliminary discussions with the Israeli Petroleum Commissioner regarding the filing and reasonably expect that the application will be acted upon by the Petroleum Council no later than October 2007.

Mr. Richard Rinberg, Zion's Chief Executive Officer, said today that: "Zion's application today for the Joseph Exploration License moves our exploration plans forward and takes us closer to the drilling of our next well, for which we continue to plan, source and purchase equipment and inventory."

Zion Oil & Gas, a Delaware corporation, explores for oil and gas in Israel.

In the event of a commercial discovery, following recovery of certain exploratory costs, Zion intends to donate 6% of its gross revenues from its Israeli petroleum rights to two charitable trusts to be established by Zion, one in Israel and one in the U.S.
