20 MINERAL RESOURCES, 1917----PART I.
Boss mine, near Goodsprings, Nev., was extensively worked in 1917,
according to the published report of the company dated January 15,
191S. Shipments were made of 442.53 tons of copper gold-platinum ore,
which carried 107 ounces of platinum and 400 ounces of palladium. Early
in 1917 this ore was refined in New Jersey, but during the summer it
was refined at the plant of the Palau Metals Co. near Los Angeles, then
beach deposits near Bullards and Marshfiold were the large producers of
platinum in Oregon, reporting a total of over 65 ounce won in 1917. A
little platinum was saved by the dredges new Sumpter and in the
hydraulic and sluice mines near Waldo and Kerby
Refiners reported the purchase of several ounces of platinum pro-duced in Washington, which may have come from the beach de-posits, from South Fork of Lewis River, or possibly from the Tul-ameen district in British Columbia.
The Rambler mine, near Holmes, Albany County, Wyo., cow tinues to produce platinum and palladium bearing copper ores. Dub ing
the year about 350 tons of concentrates were refined, which cas ried
considerable palladium and about one-third as much platinum It is
reported that recent work at greater depth in the mine has da closed a
new ore body that carries both platinum and palladium in workable
OTHER COUNTRIES. CANADA.
Tulameen district in British Columbia produced at least 71 ounces of
platinum in 1917 and probably nearer 90 ounces. Some new platinum
placers are said to have been found farther north the Rockies, one of
which appears to be a deposit that at the present prices of platinum
might be profitably worked.
The production of platinum in Colombia has increased steadily for several
years and our imports from that country in 1917, as shows by refiners'
reports, were 31,737 ounces of crude platinum. The American interests,
which are operating one dredge on the Condoto, hope to have in
operation during the summer of 1918 a second dredge which should
materially add to the Colombian output. If the prices now paid for
Colombian crude platinum, about $102 an ounce New York, are maintained,
we can expect a considerably larger pro-
