Almost a Lilac Pre-Salt, There Is a New Mine Map in Rio Grande do Sul. Study by the Geological Service of Brazil Finds Amethyst Deposit in Gaucho Lands!

The discovery from the study by the Geological Service of Brazil is that there are amethysts under a layer of agates, stones of lower value. It would be almost a lilac pre-salt. Currently, in Santana do Livramento, there is only agate mining, which can only be polished. As amethyst can be cut, it has more value.

Partial data, only from the mines visited by the Geological Service of Brazil, indicate the production of 1,689 tons of amethyst per year on the Uruguayan side. The potential on this side of the border would be equivalent. Rio Grande do Sul is already the world’s largest producer of agates and amethysts, with deposits concentrated in the north of the State.

The study literally opens a new frontier. The lead researcher is the gaucho geologist Magda Bergmann, who also ventured into history and located records of amethyst mining in the border area back in 1905.

Rio Grande do Sul Is the World Leader in Amethyst Production

Rio Grande do Sul is known for its agate deposits in the Mining District of Salto do Jacuí and world-class deposits of amethyst, located in Ametista do Sul, leading the global production of this gem.

Regarding the sizing of exploration capacity, according to the Mineral Yearbook of Rio Grande do Sul, produced by the National Mining Agency, in 2017, 4,700 tons of amethyst geodes were produced in Ametista do Sul and 8,279 tons of agates, chalcedony, etc., in Salto do Jacuí. These numbers are a model that can estimate the expected exploration here at the Border.

For geologist André Almeida Bastos, the exploration of mineral resources requires a license from the Union, under penalty of incurring in the crime of usurping Union property. “The surface land may belong to the owner, but the subsoil belongs to the Federal Government, and only it can authorize extraction,” he summarized.

When asked if the negotiation phase between landowners and those interested in exploration has begun, André replied that it has. “Our idea is to leverage this knowledge and offer opportunities to more landowners,” he revealed.

The complete study by the Geological Service of Brazil (SGB) can be accessed on this site.
