LITHIUM RIO GRANDE SOUTH PROJECT

UBICATION

The Mining Group is located in the Puna Argentina, at -3.700 MAMSL at it is approximately  1.700 km at West of Buenos Aires City. 

The prospected areas are located at the North corner of Catamarca, in the inter-provincial limit with Salta, over austral border of Rio Grande Salt Lake.

ACCESS

Properties are located at 250 km al West of Salta City, at 450 km at NNO of San Fernando del Valle de Catamarca and at 300 km at SE of Antofagasta- Chile.

Properties are accessible from San Fernando del Valle de Catamarca after a trip of -550 km up to Antofagasta de la Sierra by Provincial Route Nº 43, then up to Archibarca village up to the union of Provincial Route Nº 44 (N-S) up to the properties of interest.

The access can be made from Salta for the National Rute Nº 51 passing through San Antonio de los Cobres up to the Locality of  Pocitos, and then to South by Provincial Rute Nº 17 up to Salar de Hombre Muerto, where a detour toward West must be taken up to Antofalla Locality. From there, the road continues to NO by the rute that goes to Salar de Archibarca up to the union of Provincial Rute Nº 44 (N-S) up to the access to the properties. The access is by a paved route up to Antofagasta de la Sierra or up to   San Antonio de los Cobres and from there by a grazed route in good state.

LOGISTIC RECOURSES

The logistic resources of the zone are very basic. In Río Grande Salt there is a mining camp in Salta Province, that belonged to La Casualidad Mine, that has accommodation, kitchen, bathroom, energy provision and a limited access to satellite Internet.

The most important city that is near is Salta City, that has 608.000 inhabitants, basic accommodation services, food and health services and the service of an international airport, and has available the service of rescue for terrestrial vehicles and helicopters. The nearest locality is Antofalla, and more relevant, Antofagasta de la Sierra- Catamarca, which is -100 km distant from the properties, with  1.200 inhabitants and and basic services of accommodation. food, first aids and communications, and it has a secondary school. Currently, the airport track is in this last locality and it is operative.

Most of supplies are carried from Salta or San Antonio de los Cobres (-210 km) up to Antofagasta de la Sierra. The near mining camps are not stables, they get their energy through diesel generators and oil is transported in trucks towards them.

INFRASTRUCTURE
  • ELECTRIC SUPPLY

The electrical line with 600 MW and at 375 KV defines a line that goes between Salta (Argentina) and Mejillones (Chile), that goes  -160km at North of mining properties that are being studies. This line was built in the ‘90  to transport energy from Argentina towards Chile, and was allowed to function in 2009 due to difficulties with provincial power politics made by previous government. In February 2016 the line was allowed to function again, transmitting  110 MW from Mejillones up to the inter-connected system in Argentina.

  • GAS SUPPLY

Puna Gas Pipeline has a trace San Antonio de los Cobres- Estación Salar de Pocitos, and it is connected to Borum exploitation  in  Tincalayu Mine and Fénix Project through a 5” diameter pipeline.

  • TRAIN TRACK

The train line  works between Salta and Antofagasta passing through Pocitos Station, Caipe and Paso de Socompa Stations in Argentina through Train Line Gral. Belgrano, and Antofagasta Train Line in Chilean land. It is a narrow line, exclusively for charge, and it connects to other nets in order to access to Pacific and Atlantic Oceans. Caipe Station is approximately at 250km of the mentioned properties at the South of Salar de Rio Grande. Currently, it is used to transport borate, fruit, cattle and grain between Salta and Antofagasta, 2-3 times per week. Transport in train to the Pacific Coast represents a potential benefit.

  • CAMPING/ACCOMODATION SUPPLIES

 

In Río Grande Salt there is a mining camp in Salta Province, that belonged to La Casualidad Mine (sulfur), that has accommodation, kitchen, bathroom, energy provision and a limited access to satellite Internet. This camp utilization must be arranged through Salta Province Mining Secretary.

Antofalla Locality, the nearest one in Catamarca province, has  accommodation and feed supplies, electric calefaction but services are limited due to electric supply is got by an electrogen group.

DESCRIPTION OF THE PROPERTIES

Most of supplies are carried from Salta or San Antonio de los Cobres (-210 km) up to Antofagasta de la Sierra. The near mining camps are not stables, they get their energy through diesel generators and oil is transported in trucks towards them.

CONCLUSIONS

The mining concessions are located at salar de Rio Grande South, are 8.450,94 has, and almost all surface is covered by alluvial deposits from Recent-Holocene, occasionally covered by a thin layer of evaporites.

In the sector where are places in study, the Salar de Rio Grande behaves as a saline lake with sectors of meadows and lagoons that forms the recharge sector of the salt mine. The lithologic profile is characterized by a thin sulfation salt crust, followed by black sand and clays. The samples were taken at -90 cm depth, the brines register a conductivity near 3,4-86,9mS and a pH among 6-9. Li laws are among 2 and 234mg/L and K among 48 and 4.306mg/L.

The Li laws obtained (max. 264mg/L) in surface in properties I and II, located at the south part of Salar de Rio Grande, are similar to the ones published for the properties located north (Hains and Fouri, 2018, and literature), that registers=14-160mg/L. For the South sector of Salar de Rio Grande, this report informs Li laws up to 360mg/L obtained from wells up to 100 m depth.

In order of the geological evolution of the basin and the mentioned law, properties has a prospective interest and results old the forward move toward new stages in studies geological-mining.

Having  in mind the estimated depth of the aquifer that holds the brine is  up to  -100m, it is recommended to perform a geophysical prospection, through 15 electrical vertical sounding (SEV) in each property, that will allow the identification of conducting units that holds brines and to know those aquifer depth.

According to the results of geographical prospection other tasks of exploration can be evaluated in the future.
