Sites with sediment control, La Poma - San Carlos district:
It comprises a series of uraniferous bodies hosted at various levels (preferably Sandy), the mesocretacic of northern Argentina series, distributed on an area of 90 km of extension n-S and 60 km E.
In his almost all economic interest deposits were discovered with prospecting works air in 1959, located in the sector of Tonco-Amblayo. The largest of them was "Don Otto", which featured a continuous mineralization on surface over 2,500 meters, with useful power of 1 meter and average 0.15% U3O8. Development work met on the southern half of the deposit up to 100 meters of depth (level 0), with more than 2,000 meters of underground workings.
Deposit "Martín Güemes M. had a development in area of 300 meters, useful power of 1 meter and laws average 0.13% U3O8 and 0.5% V2O5, having explored up to 40 meters deep."
The body of "Los Berthos" presented somewhat irregular mineralization along 300 meters and laws of 0.5% U3O8 and 1% V2O5 to average 1 meter thickness. Underground workings were extended up to - 32 meters.

"Pedro Nicolás" tank presented on surface a continuous mineralization 700 meters, having certificate extension of up to 180 meters below the outcrop, with a development of approximately 300 metres above the Bank.

The body "Cachiyal", also aflorant, showed the continuity of the same to the level - 35 meters.

There are other deposits in the district such as "Pepe Luis", mineralization on 400 meters; "Emmy", about 200 meters, etc., with output power ranging from 0.6 to 1 metre and tenors media between 0.1 and 0.2% U3O8.
On other bodies such as "Don Bosco", "El Pelado", "Providencia", etc... ran minor recognition work, which showed that they are of lesser importance than the previous ones.
Reservations ("measured", "indicated" and "inferred" mineral), reached 2,000 tonnes more additional 300 tonnes of U3O8.
The extent and continuity of mineralization at surface and at depth of deposits "Don Otto", "Pedro Nicolás, "Los Berthos", "Cachiyal", etc..., and similar characteristics of bodies allowed to infer in his time, the reasonable prospect of development of the district were of the order of 14,000 tonnes of U3O8.
The dominant mineral in "Don Otto" and "Martin M. de Güemes" is the Tyuyamunite.
The dominant mineral in "Los Berthos" and "Emmy" is the Carnotite.
Ores of the district were economically concentrables by acid leaching in a station for 36,000 tons. The calcium concentrate pre obtained, with laws varying between 5 and 8 per cent of U3O8 was sent to its final refining to a plant located in the province of Córdoba.
