Curiously, but not surprisingly, the report reveals, a new mine, rarely .Is discovered in Colombia' and about 60 per cent of the countrys gold comes from placer deposits and 40. per cent from lode mines.' The virtual absence of new discoveries is attributed to the intense explorations that the Spanish conquerors and their descendants made for more than 300 years in the search for gold. In spite of this lack of- unexploited areas, new developments are expected in Colombia, prindeposits cipally in well-knothat have become available because of modern techniques and improved transportation facilities. Gold production in Colombia in modern times reached a peak in 1941 . when 656,019 ounces were produced, but as the effects of the war became more pronounced the output declined steadily. Between 1535 and 1885, it is estimated that a total of 700 to 800 million dollars in gold was produced. Included in the gold mining summary are a review of Colombias mining code, descriptions of many of the principal mines and miping areas and recent developments in the and departments province of the country.

A survey of gold mining in Colombia, South America, which has produced this precious metal for more than four centuries and in recent years has supplied about 1.4 per cent of the worlds gold, is being made available for free distribution by the Bureau of Mines as a special supplement to the December Mineral Trade Notes, Dr. R. R. Sayers, bureau director, announced today. Gold the chief objective of the Spanish Conquest of nearly 400 years ago today comes principally from five departments and one intendencia (province) of Colombia, according ' to the survey, which was compiled by James K. Cathcart, a mining engineer with long experience in Colombia. Hie report originally was made to the Metals and Minerals Division of the Foreign Economics Administration in connection with a technical mission to Colombia and now is being published by the bureau, Dr. Sayers said. The department of Antioquia, the report shows, is Colombias and leading- - gold producer, based on production both in colonial and modern times still contains in the valley of the Nechi River the richest- gold mining region of the country. In 1940, when Colombia produced 631,927 ounces of gold, Antioquia contributed 417,069 ounces or 66 per cent, and in 1944 this department mined 329,-0ounces, or 59.3 per cent of the countrys total of 553,530 ounces. Second largest gold producer in 1940 with 64,264 ounces or about 10 per cent was the intendencia of Choco, but this province yielded only 49,127 . (Continued From Page 1) physical prospecting has made rapid advances. It Is the judg-me- nt of those best qualified in the mining industry that through the application of geophysical prospecting many new ore deposits will be found in the future in the presently known mineralized areas. Those best qualified in the industry, who reject the have-n- ot theory, fully recognize that probably no new copper, lead and zinc mining districts comparable in size and importance to those of Butte, Montana; the Tri-Sta- te District; the Coeur dAlene District in Idaho, and a few others, will be discovered in the future, but they believe that through intelligent development work and with adequate metal prices there will be developed enough 'new mines to replace those that are being worked out. Mr. Reno Sales, who is recognized as one of the leading mining geologists in the world, states: If we do not find more new deposits of copper, lead, and zinc in the next forty years than were found in the past will forty, then the have-no- ts have won their argument. He is one of those, however, who subscribes to the possibility of developing substantial reserves in those areas of the United States that have not been thoroughly explored. Mr. Clinton Crane, chairman of the board of The St Joseph Lead Company, recently made a review of our reserves of copper, lead and zinc. He expressed the confidence that we now possess enough ore reserves of copper, lead, and zinc to continue to produce at the current rate or even higher rates during the next fifteen to twenty-fiv- e years, and also that our mineral resources of these metals are sufficient to meet all essential needs during the next hundred years. One must not lose sight of the re-u- se of a large percentage of our consumption of primary metal which is normally recovered through our secondary smelting operations in the treatment of scrap. This is particularly true in lead and copper, and is becoming a greater factor in zinc since the use of zinc in die casting has been substantially expanded. This secondary production will continue to supply a substantial percentage of our normal civilian consumption. I wish to present a brief review of some of our important minerals and metals to substantiate the argument that we are not becoming a have-n- ot We normally Import the major part of our bauxite require- ments from which aluminum is produced. Our bauxite production in ' 1939 was 391,000 tons. This was increased to 6,661,000 tons in 1943, and during the' seven years beginning with 1940 and including 1946 we produced domestically slightly in excess of 16,000,000 tons, which represents 69 per cent of the total bauxite used during that period. This certainly demonstrates what can be done in supplying some minerals for which we normally depend on foreign sources for our supply. Much has been said regarding the depletion of our iron ore reserves. The largest section producing iron ore in the United States is known as the Mesabi Range. Here are enormous iron ere reserves. The major part of these reserves, however, are in the deep mines, the ratio being approximately 66 per cent in the shaft mines and 34 per cent in the open pit mines. During the war it was necessary, in order to conserve manpower, to draw, heavily on the open pit reserves. About 60 per cent of the total production of ' iron ores came from the open pit mines and 40 per cent from the underground mines. The Mesabi Range will produce enormous tonnages for many years. The industry recognizes the necessity of improved benefication of the lower ores and increased mining grade costs of the deeper: deposits. It is estimated that around $600,000,000 will be spent on improvements alone for the purpose of low grade ores and mining the deeper ores. This work is now being started so that they can meet the present high requirements for a number of years. As to copper, our average annual mine production in the five years prior to World War I was 583,000 tons. From 1915 to 1919 this was increased to 851,000 tons. The average annual production during the five years prior to World War II was 625,-0tons. Average production for the five years, 1940 to 1944, was 1,000,000 tons. It is interesting to note that the average annual consumption of new copper during World War I was 650,000 tons, whereas World War II conr sumption averaged 1,500,000 tons. A substantial percentage of our copper went into munitions and was. shipped to various parts of the Allied world.

The of job moving 2200 tons of dredging equipment from . Manhattan to Copper Canyon, 16 miles northwest of Battle Mountain, approximately 170 miles, goes to a California concern. The first load of material will likely leave Manhattan within a week. The heaviest piece to be moved and which cannot be broken down into smaller segments, weighs about 40 tons. There are five of these pieces. Individual loads outside, of these 40-tchunks will probably average around 20 tons and four to five trucks will be employed, according to J. L. James superintendent for the Natomas !Co. of California, owners of the dredge. Supt James spent several at Copper Canyon recently days surveying the site for the dredge pond on placer ground leased from J. O. Greenan, the owner. The pond for the dredge is now being excavated. This operation will take 10 years op possibly more, James said. One' dredge,, a dragline, is already in operation .on the Copper Canyon property. This dredge handles about 5000 yards daily. The Manhattan bucket dredge, when in operation, will handle about 12,000 yards. Several months will be required to. move all the equipment from the Manhattan, site and the task of reassembling the dredge cannot be started until the. last piece is on the ground as this last equipment will have to be the first lowered, into the! new excavation. . -- on : . Canadians Opposed to Free Market Gold Export OTTAWA, Canada Finance Minister Abbott reiterated in the Commons die governments stand against allowing Canadian mines to sell gold in the open market at more than the U. S. pegged price of $35 an ounce. This is the price naid by the U. S. Treasury. The minister did not commit himself definitely on what action, if any,, he would take re- "T garding the recent plan of the American Smelting & Refining . v Co. to export gold refined from Canadian concentrates at more than pegged prices. While tiie minister did not say he was going to stop this he did read the statement of the International Monetary Fund, endorsed by the United States, urging that steps be taken in ' member countries to stop the internation, al traffic in gold much of which goes into private hoards and is not available for currency stabilization. We believe it is in conformity with international obligations and ip the public interest to prohibit exports of gold to this free market, said Mr. Ab-- so-cal- - bott The Western Mineral Survey for authentic reports on Mining and Oil developments in the West.
