Raise the Titanic

The film opens on the fictional island of Svardlov in the far Barents Sea north of the Soviet Union where an American spy breaks into an old mine where he discovers the frozen body of a United States Army sergeant and mining expert Jake Hobart. Next to Hobart's corpse is a newspaper from November 1911, as well as some mining tools from the early part of the 20th century. Using a radiation meter, the spy discovers that what he seeks, an extremely rare mineral named Unobtainium, was there but had been mined out leaving only traces. He is then chased and shot by Soviet forces, but is rescued at the last moment by Dirk Pitt (Richard Jordan), a former U.S. Navy officer and a clandestine operator.
