Gold Occurrences in Uruguay
Until 1997 gold was not mined in Uruguay although the potential for finding it existed and a gold mine named El Arenal in Rivera where a $30 million investment created a mine that was expected to last for six years. This start-off created a sustained growth in the mining industry that is still ongoing.
has long been noted for its exploitation of non-metallic industrial minerals it
has only been within the past few years that metallic minerals have been exploited. That coupled with significant foreign
investment has brought about a rise in production. The processing of granite is one of the
benefactors of this as well as the production of gemstones especially large amethyst lined geodes
some as large as houses and other metallic minerals.
Before the continents of
Africa and South
America split apart millions of years ago Uruguay
was joined to Namibia
in Africa making it entirely that both gold and diamonds
could be found in the country.
Although there are no volcanoes today in
there is plenty of evidence of past volcanoes and volcanism. The amethysts are associated with vast flows
of basalt that heralded the splitting of the continent of Gondwanaland when the Atlantic
Ocean opened during the Triassic/Jurassic
to form today’s deposits of basalt.
Earlier volcanic activity occurred during the Precambrian. These episodes of ancient volcanism provided
the heat engines to
cause gold to be deposited in favorable places.
Although gold is known to exist in
it still remains one of the most under-explored countries on the face of the
earth. There is known gold that has
already been contracted to a Canadian Mining Company and there are at least two
other areas containing gold that haven’t been let out on contract as of
yet. Today the country is like a
treasure chest waiting to be opened.
