NEWS RELEASE:


BONTAN CORPORATION INC. SELLS ITS .75% INTEREST IN OIL EXPLORATION PROJECT IN PAPUA NEW GUINEA AND PROFITS US$1.85 M ON OVERALL INVESTMENT

TORONTO, ON – July 8, 2005, Bontan Corporation Inc. (OTCBB: BNTNF) (“Bontan”), is pleased to announce that it has sold the remaining .75% IPI interest it held in the oil and gas exploration project operated by InterOil Corp (AMEX:IOC) for US$3.2 M to a privately held institutional investor.

Bontan will use approximately US$2.7M to fund its obligations in its Louisiana natural gas exploration project in which the Company has a 49% working interest.  On May 20, 2005, the Company received a notice of a cash call by the operator of the Louisiana project.  It is anticipated that the funds will be used to cover site preparations and drilling costs of the initial well.  The Company will use the remaining funds for working capital purposes.

CEO Kam Shah commented: “Although we believe that PNG has much potential, we were offered a premium price for our IPI interest and felt that it was prudent for the company at this time to sell our interest.  As a result we are in a solid cash position with no debt and no further liability as it relates to the IPI. We will now be focusing our attention on the 49% working interest we have in our natural gas prospect in Southern Louisiana.  The project will now be fully funded from the funds on hand and as such we have no need for any new capital infusions at this time. We are very excited by this play and together with our partners in this project, look forward to the imminent drilling dates as dictated by the availability of a drilling rig. In addition, we will continue to seek other energy exploration prospects.”
