The search for the missing Malaysia Airlines flight MH370 is not quite over, the company leading the mission has said, despite the Malaysian government stating on Monday that it had ended.

Ocean Infinity said it was heading to one last spot of interest before it turned back for good.

The Guardian has learned that the seafront exploration company’s Seabed Constructor vessel will sail to the spot in the southern Indian Ocean where a Chinese patrol ship detected an ultrasonic pulse – which could have been consistent with that from a black box – in 2014.

Analysis of the movements of the Seabed Constructor estimated that it was still monitoring or recovering its submarine detection vessels early on Thursday morning local time.

A spokesperson for Ocean Infinity confirmed the company was aware of the reports of the possible black box signal four years ago, and it was heading to the area to check it out for themselves “before we head to port and bring this search to a close”.

The Malaysian government at the beginning of the week said its search agreement with Ocean Infinity had ended and would not be extended.

Speaking on Monday, the transport minister, Anthony Loke, said the US-based company had requested an extension to conclude its undersea search for the missing plane.

Ocean Infinity’s arrangement with the Malaysian government was made on a “no-find, no-fee” basis, where the company would receive about US$70 million if it found the aircraft wreckage, and no payment if it found nothing.

After five months of extensive searching, Ocean Infinity admitted defeat on Tuesday and its chief executive, Oliver Plunkett, said it was with “a heavy heart that we end our current search without having achieved that aim”.

However, it appears that in a last-ditch effort, the Seabed Constructor will continue for at least two more days to survey a spot 25 degrees south and 101 degrees east within the original 84,000-sq-mile search zone.

The pulse detected by the Chinese ship had a frequency of 37.5kHz, the same as is emitted by flight recorders, and it was seen as one of the few hopeful moments in the first few weeks of the search for the Boeing 777, which went missing in the early hours of March 8, 2014, en route from Kuala Lumpur to Beijing.

Chinese planes had also reportedly detected debris in the area but no wreckage has subsequently been found, despite an international hunt the past four years.

Speaking on Wednesday, Loke said the search for the MH370 had cost 500m ringgit (US$126 million) and Ocean Infinity would be releasing a full report on its findings by July.

“We remain ever hopeful that we will be able to find the answers we seek and new information will come to light and that at some point in the future the aircraft will be located. We remain steadfast in our unwavering commitments to solving the mystery of MH370.”
