Huge Uraninite Specimen Possibly Collected by Martin Klaproth in the late 1700’s

Martin Klaproth discovered Uranium in 1789. This is a large and very active specimen of Pitchblende that dates to Martin Klaproth and the location where he collected the mineral. It also has a label from the museum that purchased Klaproth’s meteorite and Uranium-bearing mineral specimens. The history on the label for this specimen is that it uses an old obscure term for pitchblende, “Uranpecherz" that was discontinued around 1820. Thus, this specimen may have been collected by Martin Klaproth, as he died in 1817 and his collection was acquired by the museum prior to his death. 


Large Active Radian-Barite Specimen from the Czech Republic

RB1

RB2

RB6

Radian-Barite (aka Radiobarite) is is comprised of radium and barium sulfate. It is considered by some to be the “most radioactive substance found in nature” and webmineral.com in fact lists it as a whopping 444,528 mR/hour for 1000 grams.

However, since Radium has a half-life of about 1600 years, this level of activity is rarely found in mineral deposits. This large specimen (over 2700 grams) came from Lahošť (Jeníkov), Duchcov (Dux), Ústí Region, Bohemia (Böhmen; Boehmen) in the Czech Republic. This location is known for its Radium-Barite deposits. As shown above, the dark brown crystals of the material are readily identified by a Gamma spectrometer as Ra-226.  This type of large specimen is rarely seen on the market


The Congo

It was from the Shinkolobwe mine in the Katanga province of the Democratic Republic of the Congo that the United States acquired Uranium to supply the Manhattan Project. This area, considered a freak of nature, has some of the richest, most beautiful and hottest Uranium minerals to be found anywhere in the world. Each of the Uranium minerals below are from this region of the Congo and are from old collections that were put together before the mines were officially closed, flooded and sealed. As shown in the photos below, the colors and activity levels of these specimens are truly unique.

Canada

Bags of Uranium ore were ferried by  miners working at  Port Radium from the Eldorado mine across Great Bear Lake. The crushed ore was refined in Port Hope, Ontario. This ore also fed the Manhattan project.  As shown in the photos below,  these specimens are incredibly high grade examples of essentially pure Pitchblende / Uraninite.  The last two photos from the January 14, 1946 issues of “Life Magazine” show the the mines in the area after the end of World War II.

Germany

Classic example of pure, rich, heavy and dense Uraninite from Saxony Germany.  Wismut was a uranium mining company active in Saxony during the cold war. It produced a total of 230,400 tons of uranium between 1947 and 1990 and made East Germany the fourth largest producer of uranium ore in the world at the time.

Uraninite from Schlema, Germany. 240,000 CPM and 80 mR/hr. 



The Czech Republic

This region of the world in considered the birthplace of large-scale Uranium mining. The botryoidal specimens from these locations are incredibly active. Several localities in Czechoslovakia were mined by the former Soviet Union during the cold war. The largest deposits were in Pribram and these locations yielded about 50,000 tons of Uranium.

The United States

Two stunningly beautiful and superbly active historical specimens of Schoepite  Gummite and dendritic Uraninite from the Ruggles Mine in Grafton New Hampshire. The top three photos show a superior slab specimen that was collected by the well-known geologist Benjamin Shaub in 1938 (see photos for additional details). The next three show a massive 4082 gram (nine pound) uncut and unpolished chunk of the same material. 

The next two photos are from the famous Mi Vida mine. On July 6, 1952, Charlie Steen found an extremely large and very high grade deposit of Pitchblende in Lisbon Valley, southeast of Moab, Utah. His story was one of incredible perseverance through hardship until he found what he was looking for. He named it the "Mi Vida" mine (My Life), and it was the first big strike of the uranium boom. Steen made millions off his claims, which prompted a "Uranium Rush" of prospectors into the Four Corners region. Those who knew him describe him as a very generous man who gave back to the community in terms of education and housing for workers. He died in 2006 with most of his fortune lost to various investments. The ashes of Charlie Steen and his wife Minnie Lee were scattered at the Mi Vida site. The mine is no longer active.

The Mi Vida specimens are followed by a very rare high grade drill core sample is from the Hack #2 mine Coconino, Arizona. The sample was taken in 1965. Finally, the photo at the bottom of the page shows an enormous 105 pound piece of petrified wood with Carnotite from the Anaconda mine in New Mexico. Note the penny in the first photo for size reference. This piece was collected decades ago by a mine foreman working in the Uranium mine. The piece looks like a recent piece of tree trunk until you touch it and then try to lift it. It is SOLID rock - and replete with Carnotite and perhaps some Uraninite too in a particularly hot area of the specimen (the last photo in the series).

It is difficult to gauge or report the radioactivity of this specimen due to its sheer size. Any Geiger counter measure obviously underestimates the radioactivity of the specimen in its totality because the probe on the counter covers such a small area of the surface. At the surface, the specimen ranges up to 100,000 CPM and 25 mR/hr. And, it measures about 200 to 300 CPM from several feet away. There are cracks running through the specimen as can be seen in the photos as would be expected with a specimen that is perhaps as much as 150 million years old (exact carbon dating not available).
