The Requa/Herbert Hoover Gold Mining Files - Barrick Golds Beginnings

The following information from the Herbert Hoover/Requa files demonstrates the beginnings of Barrick Gold.
 See Source below for full details.


~ The Requa/Herbert Hoover Gold Mining Files ~
Aka: The Requa/Hoover/Milbank/Lewisohn/Steen/Combined-Metals/Bunker-Hill Files as

complied by four generations of Requa family members with former U.S. President/Geologist
Herbert Hoover, Hoover sons Herbert and Alan, Jeremiah Milbank Sr, Jeremiah Milbank Jr.,
Combined Metals Reduction Company, Adolph Lewisohn, Lewisohn Bros, Charles Steen, El
Paso Gas, Bunker Hill Mining Company, and numerous others.

Part I:
During the 1930s Herbert Hoover (following his White House years) with fellow geologist Mark L.
Requa — who had engineered Hoover’s 1928 nomination for the presidency and his subsequent

campaigns developed the Mercur Gold Mine in Utah into production; and, they had spent under the

management of Lawrence K. Requa (in 1930’s dollars) over $1,000,000. Production was then shortly

thereafter curtailed due to metallurgical difficulties developed and not possible then to solve (carbon in

the ore), but that then were possible to solve in the 1970s when Getty Oil acquired the mine properties

which Barrick Gold acquired and then went public on in 1983.

The comprehensive mining data of the 1930s that defined the gold deposits was provided to them by

Lawrence Requa, unused for 40 years. It was this Mercur Gold Mine, and the Requa/Hoover data on

the established gold reserves to be produced there, upon which basis Barrick Gold (having acquired
rights to the mine from Getty Oil) then went public in 1983. Mercur had been a mine “set to go” since

the 1930s. In 1985 Barrick closed their agreement with Getty and paid $31 million with royalties
(considered to have been a “fire sale” price). A news article from the time is noted by the link below:,97562
The large overall Requa/Herbert Hoover Files on countless such mining sites were consolidated by

the Requa family from its one hundred years of mining activities throughout the Western Hemisphere

from Alaska to Bolivia. It detailed thousands of gold and other mineral showings and mines that were

deemed of merit for further mining exploration and/or development, some having been put into
noteworthy mining production, from the 1930s to 1970s or into then-pending mining production

by the Requas, the Hoover family, the Milbanks, the Lewisohns, Charles Steen, and the many other
mining interests allied with them. These were the most major mining financiers of their time

expending their essentially-limitless available mining finance funds in both exploration and

development. Seen below are Hoover and Mark Requa in 1928 and early 1930s (White House Years),

and then Hoover with L.K. Requa, after Mercur, in Idaho in late 1930s at their mining site there:

In 1993 it is certain that this compilation of data from almost a century by four generations of Requa
family comprised the most extensive and largely still unexploited database for gold exploration


and development in the world. As such, it was viewed by those knowledgeable about it as the most
valuable mining database for the Western Hemisphere certain to provide the critical data basis for

producing many gold, silver, and base metal mines throughout the Hemisphere such as at the

Mercur Gold Mine that Barrick Gold went public on, based on that 1930s data, and then began

producing over 100,000 ounces of gold a year.
The great value of the combined Requa/Hoover Files with just one of its documented mines made

possible to take public in 1983 by the now-largest gold mining company in the world consisted of

similar data on many hundreds of mining sites throughout the Western Hemisphere. The Mercur Mine

data had been acquired in the 1930s by Hoover, Mark Requa, and Lawrence Requa. Data on these

additional hundreds of mining sites was acquired by the additional expenditures of the greatest possible

funds available then in mining by the greatest mining capitalists of the era up through the 1970s: the

Milbanks, Hoovers, the Lewisohns, Charles Steen, and others. Well into the hundreds of millions of

dollars had been spent to acquire the data in the Requa/Hoover Files.

Noted geologist John Prochnau, who had several meeting with Lawence Requa in a recorded interview

in 2001 stated the following regarding the Requa family and these files:
“Lawrence Requa...was a very well known mining geologist in Nevada and throughout the world

and the third generation of a family of very prominent mining engineers and entrepreneurs that

began with the great grandfather who came to California in the Gold Rush and had a very

successful career in developing mines there, and following with the grandfather Mark Requa who

was an associate and very close friend, business associate, and campaign manager for Herbert

Hoover, another famous American mining engineer who became President of the United States in

1928 to 1932.
[The files in 1992] were stored in a very large room full of filing cabinets that contained files on

various properties…and in my view they probably contained very valuable information. That kind

of information is of extraordinary interest and value. I think the real value of those files is that

they provided information that's not available from any other source, including any modern

technique that you can imagine, because it involves investigations of former workings that are

now inaccessible and can never be re-sampled. That's where the real value lies.

Regarding his experience in the late 1980s with viewing these files, geologist Dan McCullar stated in

the same series of interviews the following:

" Some of these files would be typed paper, some bound volumes. I remember seeing handwritten

notes, some in pencil, some in pen, maps, lots of exclamation points, underlines, and identifying

marks that would indicate that certain files were of extreme importance, that their prospective

nature was of high value.

"I remember specifically files from Central America and Honduras, the fact that Honduras was

heavily forested and his father has spent an enormous amount of time travelling the rivers and

hiking up the river valleys, mapping the outcrops, describing the mineralised areas that would not
be easily seen by air photos.

“...They were all very carefully categorized by geographic regions. Some files had the most

amazing things written [by Lawrence Requa], notes attached, some paper clipped attached, some


type written pages, descriptions of individual areas, some hand drawn maps, some published
maps with handwritten notes on the maps that identified geologic features on the maps.

Part II: Historical Details of Record Regarding the Evolution of the Requa/Herbert

Hoover Files
In addition to Herbert Hoover those involved in compiling the data with Lawrence

Requa and with very great expenditures of funds over considerable time were those in

association with Lewisohn Bros. of New York City. Founders of said firm included those
of note at: link with this excerpt of public

record about that said firm´s very notable and historically illustrious founders of great

Adolph Lewisohn (born May 27, 1849 in Hamburg; died August 17, 1938 in Upper

Saranac Lake, NY) was a Hamburg-born German-American businessman who,

together with his brother Leonard (1847-1902), once led one of the most important

and profitable copper companies in the United States. In the 1880s, their company,

Lewisohn Bros., broke new ground in the electrolytic processing of copper and

helped a whole industrial process take root in the American copper industry.

Through their involvement in the Butte & Boston Consolidated Mining Company

(B&B), the Lewisohns increased their stake in the industry and managed to

accumulate a significant fortune in the brief period between 1887 and 1900. After
Leonard’s death in 1902, Adolph Lewisohn managed the business on his own. In the
following years, however, he began to devote more of his time and efforts to

philanthropy, and he put his considerable riches in the service of an enormous

range of social, cultural, and educational initiatives. His charitable giving focused

primarily on institutions in New York City, where he lived for seventy years. Given

the extent of his philanthropic contributions to the city, some considered Lewisohn
“New York’s most useful citizen.”
L.K. Requa mining associate Adolf Lewison (and his successors at Lewisohn Bros.)
may thus also favourably be compared to the Requas’ long-term Hoover associate Jeremiah

Milbank who was likewise a mining financier of vast resources in the Pres. Herbert

Hoover / Mark L. Requa sphere with the Lewisohns (and in the later Herbert Hoover /

Lawrence Requa sphere). As previously written of Jeremiah Milbank has been the

Of Jeremiah Milbank it will be perhaps news to most that the great

cinematographer Cecil B. DeMille wrote this of him: “There is a persistent myth that
capitalists think of nothing but capital . . . I have known a certain number of very rich

men who were scamps and a larger number who were just dullards; but two of the

finest men I have ever known, with the largest minds and highest ideals, were also men
of great financial power. One of them is Jeremiah Milbank”. For DeMille, Jeremiah

Milbank single-handedly financed one of the biggest Hollywood block-buster budgets of

all time in DeMille´s production in 1927 of King of Kings, the first major Hollywood

production with a cast of thousands based on the life of Jesus Christ. Such ability by

Milbank to expend vast capital was then, with Herbert Hoover and with famed
geologist L.K. Requa, turned to Central America and mining.

These financiers had essentially limitless funds to expend which translated into

vast expenditures and compilations of unprecedented quantities of mining and

exploration data all under Lawrence Requa`s organization

The same mining finance capabilities applied to Uranium Boom King Charles Steen

for whom Lawrence Requa quickly supplied one of his most trusted surveyors to survey

his discovery and claims immediately upon its discovery Steen`s bonanza uranium
discovery claims the largest and richest discovery ever and at the height of uranium

prices in the 1950s. Said provision of a surveyor by Requa to Steen (Clare Hagen) was
made to avert any claim jumpers who did arrive as expected, but to no avail due to the

expert surveying quickly arranged by Lawrence Requa. Charles Steen then spent large

capital, from his Bonanza strike, in Honduras under the geological guidance of Lawrence


Exploration and mining data was thus compiled at the cost of hundreds of millions
of dollars of expense over 70 years of the historical and famous Requa Family mining


The picture below was taken of Lawrence Requa on a raft on the Tipuani River in a

major set of investigations and expeditions by Lawrence Requa in collaboration with the

aforesaid Lewisohn Bros, financiers of New York into that Bolivian district. Thus, on the

Tipuani River below is pictured Lawrence Requa undertaking the extended evaluations,

from historical records and new data to be made, of the very large gold mining potential

for that district with 33 million ounces of historical gold production.

Indicative of the value of the Tipuani files gathered by Requa is this 2008


A 2008 Abstract Report states:

In addition to the gold-bearing placers associated with deposits of the present
drainage system, gold has been mined in the Tipuani region from a belt of Tertiary

conglomerate ("cangalli") filling the deep channel of a former stream whose original steep

gradient was further steepened by faulting and tilting during an episode of Andean uplift.

The conglomerate consists of cobbles and boulders of slate, granite, and quartzite which

together with finer-grained material are cemented by iron oxide; pay streaks have been

found both close to bedrock (folded Devonian shales) at the bottom of the main and

subsidiary channels, and at higher levels. High-temperature gold and tin lodes associated

with granitic batholiths in the headwater region of the Tipuani river are assumed to be

the source of metals in the cangalli.

This is what Lawrence Requa and Lewisohn Bros. spent millions of dollars to

evaluate regarding 33 million ounces already produced.

The ability by Jeremia Milbank to expend vast capital was, with Herbert Hoover
and Requa, turned to Central America and mining as seen in the following page items:

Jeremiah Milbank** Hoover´s son Allan, L. K. Requa, and Jeremiah Milbank

Later Years Together on horseback in Central America
Note above link.
** Fortune magazine calls the Milbank clan “one of the oldest, richest, most proper and least publicized in

the American business community”.
This work was greatly expanded by additional millions of dollars expended by U.S.
“Uranium Boom King” Charles Steen in both the evaluation of gold mining opportunities

and in the development of some of these to a present gold production status. One of these
provides a ready-made mine, with $14 million in present dollar values having been

expended by Steen, to bring this mine to gold production status, with 9000 feet of

underground workings in established gold deposits.

Geologist L.K. Requa was the third in a family line of famous U.S. mining

professionals and entrepreneurs. More remarkably, the magnitude of the expenditures

made by these mining professionals and financiers to produce their evaluations is to be

ascertained: into the hundred million dollar range and likely more.

This was an unprecedented sum for a geologist to commence regional evaluations of

Central America´s mining opportunities, and then to carry on the follow-up developments
that transpired from 1940 for over 30 years in Central America until 1970. Ascertaining

the ability of L.K. Requa to be availed of such unprecedented funds for such a venture at

that time and for such a length of time has resulted in the recognition that this derived
from the prior major U.S. historical events revolving around his father Mark L. Requa

who had in fact organized the uppermost leadership of the largest U.S. oil industry

corporations into backing and then making Herbert Hoover the President of the United

States. The position and ability of Mark Requa to do this derived from his appointment

by President Woodrow Wilson in 1918 as the U.S. federal Oil Director to direct and

allocate the entire oil production of the U.S. during World War I. This is noted in one

source below:
“To ensure adequate supplies, effective distribution, and appropriate allocation [of oil
during WW I], President Wilson appointed Mark L. Requa as the first Fuel administrator

(Secretary of Energy). His job was to create a working relationship between the

government and oil industry to accomplish the above goals. The close working

relationship that evolved was in marked contrast to the feud between the government
and Standard Oil years earlier”.
See link:

The appointment of Requa, his evolving rapport with all the leading oil men, and the very

great power he wielded throughout the oil industry leadership, is clarified in these
successive links to New York Times front page articles from January through March of

The extent of Herbert Hoover´s and Mark Requa`s joint access to the White House and to

some most remarkably powerful financiers even in 1917 has been determined from

records of Herbert Hoover´s appointment books that note his and Requa´s meetings with

President Woodrow Wilson and other powerful financiers from June through October of


These have shown the 1917 gatherings in Washington D.C. of Hoover, Requa,

Whitmarsh, Baruch, Warburg, President Woodrow Wilson:
Mark L Requa is listed with Hoover on June 6th, 7th, 8th, & 27th, 1917, and July 2, 1917 along with

Woodrow Wilson; on July 18, 1917 along with Theodore Whitmarsh who would become a director of the

Federal Reserve in 1931; and July 19th, 23rd, 28th, & 31st; Aug. 6th, 9th, 13, 14, 15th with Whitmarsh

again, and 18th, 21st, 27th, 28th, 29th, 30th, 1917; Sept. 5,6,7,8,9,10,11,12,13,14 along with Bernard Baruch,

Sept 17,18,20,21,22, 24th along with James F. Byrnes, Sept. 25 along with Bernard Baruch. Oct. 1,2,3,4th

along with Bernard Baruch, Whitmarsh & War Industries Board, Oct 5,6,7th along with Woodrow

Wilson, Oct. 10,11, 12, 13, 14, 15, 16, 17, 18, 19th along with Paul M Warburg, etc. During the time just

following Mark L. Requa would be appointed to control the entire oil production and allocation of the

U.S. during WWI.
A few months later President Wilson appointed Mark L. Requa as Oil Director. After the
war Requa engaged in food relief programs with Hoover for Belgium and elsewhere.

During Hoover´s tenure as Commerce Secretary, Requa was then able to marshal the

support of the oil industry leadership to accomplish the nomination and election of

Hoover as President. In addition to Mark Requa, one of Hoover´s closest friends and

political allies was Jeremiah Milbank. Thus it was that Hoover, Milbank, and others with

essentially limitless means, then financed L.K. Requa to an unprecedented extent after

his father Mark´s death to undertake the mining development of Central America.

Thus, with these unprecedented funds held by Milbank, Hoover, Lewison Bros, and many

others, and then later with those of uranium magnate Charles Steen, a vast amount of

geological and mining work throughout Central America was done in the 1940´s through

the 1960´s covering over 100 sites. Mines were mined, gold reserves were established and

brought near to production, and opportunities almost certain to yield gold reserves and

gold mines were defined throughout the region.
