KUALA LUMPUR, Malaysia -- Malaysia says it will release a preliminary report of its investigation into Malaysia Airlines Flight 370 on Thursday, more than seven weeks after the plane vanished with 239 people on board.
Defense Minister Hishammuddin Hussein said the report will be similar to the one the government sent to the International Civil Aviation Organization.
The Boeing 777 jet disappeared March 8 while traveling from Kuala Lumpur, Malaysia, to Beijing. Officials are still searching for the plane, which is believed to have crashed in the southern Indian Ocean.
Radar and satellite data show the jet veered far off course for unknown reasons. An analysis indicates it would have run out of fuel in the ocean off western Australia where a massive multinational hunt has been focused, but not one piece of confirmed debris has been found.
The air search for the plane was called off this week.
Hishammuddin, who is also acting transport minister, said he will go to Australia next week to discuss the next phase of the search, a greatly expanded underwater hunt, and the cost involved.
The head of the Australian agency leading the search has predicted that the search could drag on for as long as a year. The agency has also dismissed a claim by a resource survey company that it found possible plane wreckage in the northern Bay of Bengal.
The location cited by Australia-based GeoResonance Pty Ltd. is thousands of miles north of a remote area in the Indian Ocean where the search for Flight 370 has been concentrated for weeks.
"The Australian led search is relying on information from satellite and other data to determine the missing aircraft's location. The location specified by the GeoResonance report is not within the search arc derived from this data," the Joint Agency Coordination Center, which is heading up the search off Australia's west coast, said in a statement on Tuesday. "The joint international team is satisfied that the final resting place of the missing aircraft is in the southerly portion of the search arc."
GeoResonance said in a statement sent Tuesday to CBS News that it had discovered materials "believed to be the wreckage of a commercial airliner" about 100 miles south of Bangladesh in the Bay of Bengal using proprietary technology which scans vast areas for specific metals or minerals.
GeoResonance stressed that it is not certain it found the Malaysia Airlines plane which vanished on March 8 during a flight from Kuala Lumpur to Beijing, but called for its findings to be investigated.
The company uses imaging, radiation chemistry and other technologies to search for oil, gas or mineral deposits. In hunting for Flight 370, it used the same technology to look on the ocean floor for chemical elements that would be present in a Boeing 777: aluminum, titanium, jet fuel residue and others.
GeoResonance compared multispectral images taken March 5 and March 10 - before and after the plane's disappearance - and found a specific area where the data varied between those dates, it said in a statement.
Malaysian Defense Minister Hishammuddin Hussein said Tuesday that China and Australia were aware of the announcement. "Malaysia is working with its international partners to assess the credibility of this information," a statement from his office said.
GeoResonance said it began trying to find the plane before the official search area moved to the southern Indian Ocean.
India, Bangladesh and other countries to the north have said they never detected the plane in their airspace. The jet had contact with a satellite from British company Inmarsat for a few more hours, and investigators have concluded from that data that the flight ended in the southern Indian Ocean.
No wreckage from the plane has been found, and an aerial search for surface debris ended Monday after six weeks of fruitless hunting. An unmanned sub is continuing to search underwater in an area where sounds consistent with a plane's black box were detected earlier this month. Additional equipment is expected to be brought in within the next few weeks to scour an expanded underwater area. That search could drag on for eight months.
