“Venezuela’s Magnetic Mountain”, Harry Chapin Plummer, Popular Mechanics, July, 1949

Prep time for this blog has had me looking through old journals and publications partly because I get a kick out of the more un-self-conscious, optimistic (exuberant?) mid-20th century reporting compared to today’s dour, blame-America-first, Chicken Little iterations.

Something else that impresses me upon reading this over 70 years after its publication, is how accurate it was in reflecting the plans being made in 1949. There were, of course, some changes to the plans, as there are in all good plans. However, these great American companies were pretty thorough in their operations.

Enjoy:

When the Conquistadores of old Spain explored the jungle country of eastern Venezuela four centuries ago, the native Indians told them tales of a strange mountain which attracted lightning. Later the Spaniards saw for themselves this magic mound which, when struck by a lightning bolt, game forth a spray of flashes. The Spaniards dubbed the mountain “El Florero” — the Flower Pot — because the lightning flashes looked like flowers growing from the peak.

Today that mound has been found to hold one of the world’s richest iron-ore deposits. 

Credit for that discovery goes to an alert Venezuelan mining inspector, Eduardo Boccardo. In 1926 he determined to penetrate beyond the superstitions of the natives and to find out why the mountain was one of the spots most frequently struck by lightning on the South American continent. What he discovered was a fabulously rich lode of iron ore which, by magnetic attraction, drew lightning to the mountain. The Spaniards, intent upon their quest for gold and silver, had passed up a deposit so valuable that even now its riches can be only estimated.

Surveys of that part of the mountain granted to Boccardo show that about 35,000,000 tons of mineral rich in iron underlay his concession. Assays have proved that this ore actually is 55 to 68 percent iron. Absolutely pure iron ore is made up of 72 percent iron and 28 percent oxygen. The iron content of Minnesota’s famous Mesabi range is about 57 to 63 percent. On this basis, the Flower Pot represents one of the most important discoveries of the century in the field of metallurgy.

Naturally, it didn’t take industry long to jump into this whopping mountain of ore. Today the Iron Mines Company of Venezuela, organized as a subsidiary of the Bethlehem Steel Company of the United States, already has a small army of employees in the jungles near the Orinoco. Their task is to form a modern mining industry in the heart of the forests. They are at work between El Pao, the ore site, and Palua, the loading point on the Orinoco.

The task of these workers is staggering. They must build the mines and the port, highway and railway — even their own homes in the wilderness. Already they have completed a highway more than 14 miles long which eventually will serve as the right-of-way for a standard-gauge railway, the vital artery from the mines to the river. This railroad will have a steep grade from sea level to the mines. 

When the harbor and dock installations, the roads and railways finally are completed, the ore will move by truck and train from the mines to the ships on the Orinoco. It then will travel aboard a fleet of ore carriers, especially built for the purpose, to the blast furnaces at Baltimore, Md. 

It is estimated that production will rise to 3,000,000 tons of ore annually from ore reserves that will last a quarter of a century.

Already rolling along the uncompleted rail line is a 1500-horsepower diesel locomotive. When the track is completed, the railroad will have four locomotives, 100 ore cars with a capacity of 70 tons each, eight boxcars, four tank cars and a crane.

Before the end of this year the ore will begin to flow from the mines atop the magnetic mountain. There crews especially trained for the job will perforate and excavate the rock and earth, which will be picked up by four gigantic electric shovels each capable of taking a huge bite out of the ground. The shovels will load the ore into trailer-trucks hauled by tractors. From there it will be taken to big ore crushers — one of them said to be the largest in the world. The fragments of crushed ore will be carried by an aerial cable arrangement to the waiting ore cars on the railway.

It is estimated that about 10,000 tons of the rich earth will be hauled down the mountainside every working day.

When the ore reaches the harbor, it will be dumped into a huge storage area. An ingenious series of chutes at the base of the area will drop each load into an underground conveyor installed in a tunnel. After passing through the earth, it will climb up a huge loading bridge which extends like a pointing finger over the waters of the Orinoco. The load will slide by toboggan into 4000-ton lighters. Tugs then will pick up six of the lighters form them into a train and haul them downriver to the Gulf of Paria. From there the new 24,000-ton ore carriers will take the ore by ocean to Baltimore.

This modern industrial system in the heart of the jungle is within the orbit of Ciudad Bolivar, the principal river port of the Orinoco and the administrative and financial center of the region watered by the river.

Almost due south of Ciudad Bolivar the United States Steel Corporation has been conducting explorations of another area that appears to have huge ore deposits. it seems likely that the same vein which crops out atop the magnetic mountain also appears in this new area [the author was correct: that ‘new area’ became known as Cerro Bolivar, one of the greatest ore finds ever].

Reports state that the mineral deposits found in this second area are of a high quality, satisfactory for smelting in open hearth furnaces.

These two ore strikes are the second great boon to Venezuelan national within the past half-century. The first was the discovery of petroleum around Lake Maracaibo. Huge investments in drilling and pumping equipment, pipe lines, railways, bridges, community settlements, hospitals, and schools have been made by the participating oil companies.

Venezuela has enacted a law which requires the oil companies, both foreign and national, to refine within the country a percentage of the crude oil that is recovered. The purpose, of course, is to have a supply of domestic oil. It is anticipated that similar legislation will apply to recoveries of iron ore, and that eventually there will be smelting operations within Venezuela [a major understatement, of course].

Such a development would place Venezuela in the forefront of South American nations which at the turn of the century were dependent upon agriculture — cattle, coffee, sugar, cacao, tobacco, and rubber growing.

Thus the magic mountain that attracts lightning may revolutionize the economy of a nation.
