Columbium, which melts at a torrid 4,380∞ Fahrenheit, finds uses in turbo-jet and rocket engines where it improves heat resisting qualities and impact strength of other metals. Dr. E. H. Nickel, of Federal Department of Mines and Technical Surveys, examines rock sections of columbium ore with petrographic microscope.

Though extensive exploration in the Oka area has proven up large quantities of columbium-bearing ore, the search for this jet-age metal has extended to Great Slave Lake, where columbite ores are to-day being processed in a 125-ton a day capacity mill. Columbium stands at head of scarce metal list, and its rarity, has kept prices high; pure columbium metal powder commands $119 a pound. Magnetometer survey is shown being carried out in St. Joseph du Lac area, near Oka. P.Q.

Geologist A. C. Turnock, using a Scintillator radiation meter, checks radioactivity of core samples of columbium taken from farm near Oka, P.Q. Columbium is one of four 20th Century minerals (others: lithium, tantalum and titanium) which to-day are finding uses in everything from jets to jazz-records.

In Oka's Le Baronnet Hotel, prospector Cy Ross illustrates to manager Paul Brisbois that hotel has what is probably the only radio-active dance floor in Canada. Source (which may have been placed there by pranksters) radiates .015 milleroentgens per hour. Besides the high heat-resisting qualities that make it a natural for jet engines, columbium's affinity for gases has led it to being used extensively by the vacuum tube industry.

Long-noted for its Trappist monastery and the quality of its famous cheese, the French-Canadian hamlet of Oka, P.Q., today boasts the distinction of being the heart of a mining exploration boom. With pyramid-like drilling rigs fast becoming a part of Oka's pastoral scene, geologists and prospectors arc heightening their search for Columbium, one of a host of miracle minerals spawned by the atomic age.
