Malaysia plane 'wreckage' assessed
The company stressed in a statement that a link to Malaysia Airlines Flight 370 - missing since March 8 - is not certain, but it called for its findings to be investigated.
GeoResonance typically uses remote sensing technology to look for oil, gas and mineral deposits.
It used the same technology to look for chemical elements in aircraft, such as aluminium, titanium and jet fuel residue.
The location it identified is 118 miles south of Bangladesh, far from where the search has so far focused.
