Mining of Laguna Salada near-surface uranium deposit possible with "healthy operating margin even at current uranium prices": On Aug. 5, 2014, U3O8 Corp. reported a favourable Preliminary Economic Assessment ("PEA") on its Laguna Salada deposit: "the project would have a healthy operating margin even at current uranium prices".
Continuous surface mining scenario to be contemplated for Laguna Salada deposit:
The Laguna Salada Project is a near-surface, free-digging deposit. Mineralization lies within three metres of surface in soft, pebbly gravel that requires no blasting before mining and no crushing prior to beneficiation. The soft gravel could be excavated with a continuous surface miner, which is the preferred option being contemplated in the Preliminary Economic Assessment expected for release in Q4 2013.
"One could picture the continuous surface mining concept as a long shallow trench that migrates sideways across a gravel plain with gravel being removed from the leading edge of the trench, washed, and replaced on the trailing edge. This mining option would be expected to see 95% of the original gravel returned to the excavated area, reshaped to its original topography and revegetated with shrubs transplanted from the advancing side of the trench. After mining, there would be little evidence that mining had occurred." (U3O8 Corp. Sep. 26, 2013)
CNEA seeks to clarify Cerro Solo strategy early 2005: Argentina's atomic energy commission, the CNEA, will clarify early in 2005 its strategy for restarting work at its Cerro Solo uranium deposit in the southern province of Chubut, according to CNEA geology chief Luis López. The strategy will involve forming a partnership with a private company, launching a new auction for the project or seeking a third, as yet unclear alternative, López said. (BNamericas Dec 8, 2004)
Further delay ahead for Cerro Solo sell-off: Argentina's atomic energy commission (CNEA) will not be able to proceed with the sell-off of the Cerro Solo uranium deposit in Chubut province until the beginning of 2004 due to a change of provincial government after elections on November 2, 2003. The CNEA will have to wait for the new parliament in the southern province to define the area around Cerro Solo as an exclusion zone with respect to a law prohibiting open-pit mining there. (BNamericas Sep 10, 2003)
Additional interested parties will be sought in a new auction, to be held in 45-60 days, for the Cerro Solo uranium deposit, according to a source from the National Commission of Atomic Energy (CNEA). The CNEA earlier rejected a bid from the consortium of mining company Mining World and Canadian consultant John Thomson because "it did not comply with the tender's requirements". The Cerro Solo deposit, in Chubut province, has 4600 tonnes U3O8 (3900 tU) in reserves, including 2600 tonnes U3O8 (2205 tU) proven and 2000 tonnes U3O8 (1696 tU) probable. The proven ore grade is estimated at about 0.35% U3O8. (UI News Briefing 01.14, April 4, 2001; CNN March 27, 2001)
Judicial hearing on open pit mining in the Quebrada de Humahuaca suspended: The Administrative Court of Jujuy, chaired by Judge Sebastián Damiano, decided to suspend the hearing scheduled for Tuesday February 28, on the appeal filed by Los Vecinos Autoconvocados de Tilcara y Juella to stop the opening of a surface mine. The suspension was at the request of the company Uranio del Sur S.A., who intends to carry out the exploitation of uranium in the Quebrada de Humahuaca. (Jujuy al Día, Feb. 29, 2012)

High court halts uranium mining project in UNESCO World Heritage area Quebrada de Humahuaca:
An Argentine high court halted the project of a foreign company to mine uranium in an open-pit mine in Quebrada de Humahuaca in the northern part of the country, declared a World Heritage of Humanity site in 2003, the local press said Saturday (Apr. 24).
The decision of the Supreme Court of Jujuy province , handed down in February but made known to the interested parties just this week, favored the suit for protection filed by inhabitants and environmentalists of the town of Tilcara, which is near Quebrada de Humahuaca.
It denied a ruling by a court of appeals favorable to the interests of the mining company Uranio del Sur, and also obliges the company to show that its project would not contaminate the environment.
The Supreme Court of Jujuy halted the mining project "until it is shown that there is no possibility or certain danger that the work carried out in the area will cause contamination or environmental damage," according to the court ruling published in the Buenos Aires newspaper Pagina/12. The court said that "it is the duty of judges" to immediately "make effective the judicial protection of the reserve and of the collective interests" of the villages near the Quebrada de Humahuaca. In that sense, the ruling said that what must be protected is "the fundamental human right to a healthy, uncontaminated environment, doing whatever is necessary" to secure it.
"It is an absurd contradiction to allow further exploitation, such as open-pit mining, in a reserve declared a World Cultural and Natural Heritage of Humanity site" by UNESCO, it said. The court also warned that the title of World Heritage of Humanity "can be revoked" and if that happened "it would surely damage the tourism infrastructure now in place" in the Quebrada de Humahuaca, a deep, narrow ravine between peaks of the Andes. Uranio del Sur is a subsidiary of Switzerland-based Uranio AG, the majority shareholder of Canadian mining company Rome Resources Ltd., according to the suit brought by environmentalists and local inhabitants.

Provincial government and CNEA continue uranium exploration in La Rioja, despite legislation prohibiting it:
In a statement, the NGO Asamblea Riojana Capital de Ciudadanos por la Vida denounced "the continuing of uranium mining projects" in the Capital department "despite the existence of the ordinance enacted on August 14, 2012" which declared this town "nontoxic, no-nuclear and environmentally sustainable."
The complaint realizes that the Department of Environment of the province on Aug. 27, a few days after the enactment of the ordinance, issued resolution 268 which approved the "Updating of the environmental impact report" for one of the enterprises. This was the CNEA authorization to "continue the work done in the area of the Sierra del Velazco, in the municipalities near El Cantadero", at a distance of about 20 kilometers from the capital, the most populated city in the province, the environmentalists said.

Positive Preliminary Economic Assessment announced for Ivana deposit of Amarillo Grande project:
On February 27, 2019, Blue Sky Uranium Corp. announced the results of the first Preliminary Economic Assessment ("PEA") for the Ivana Uranium-Vanadium deposit at the Company's 100% owned Amarillo Grande Project in Rio Negro Province, Argentina: "The PEA demonstrates robust economics for a surficial mining operation of the Ivana deposit, with 13 years of uranium and vanadium production." The PEA assumes a uranium price of US$ 50/lb U3O8 and a vanadium price of US$ 15/lb V2O5.
The Ivana operation will consist of surface mining operation delivering mill feed to a nearby processing plant or stockpiles. The annual mining rate will be approximately 4.7 Mtpa (13,000 tpd) consisting of waste material and mill feed. The surface mine will be relatively shallow, with a maximum depth of 30 metres. The length of the mine will be approximately 3000 metres with widths ranging from 100 to 400 metres. The materials mined are unconsolidated gravels and sands and are free digging, therefore drill and blast operations will not be required. Waste materials will be placed out of pit for the first few years. Waste will then be placed either into external dumps or used as in-pit backfill.
Feed material will first be processed through the leach feed preparation plant, a semi-mobile screening and scrubbing facility located at the proposed mining site. The leach feed preparation plant will liberate fine material (<100 µm) from the larger particles (>100 µm) and scrub away and recover fine uranium and vanadium mineral particles coating the large particles, into a leach feed slurry. The rejected coarse fraction (approx. 75% of the mill feed mass from which most of the original uranium and vanadium has been stripped) will be dewatered, stockpiled, and backhauled by the mine fleet to the dump sites or backfilled into the mine excavation.
In the second process stage the slurry containing the fine fraction of the mineralized material will be pumped to the leach plant. An alkaline leach circuit (sodium carbonate and bicarbonate) will be used to dissolve uranium and vanadium from the leach feed minerals. No oxidant is required. Subsequently, uranium and vanadium will be separated by selective chemical precipitation, with uranium solids then calcined to U3O8 or UO3 and vanadium solids calcined to V2O5.
Tailings slurry from the alkaline leach circuit (approx. 25% of the mill feed mass and from which the majority of uranium and vanadium has been stripped) will initially be pumped to a surface tailings management facility (TMF) where it will settle and release water. In later years, the fine tailings will be pumped into containment cells in mined out sections of the pit, for co-disposal with mine waste rock and coarse rejects.

Opposition to uranium exploration in protected area hosting dinosaur and other fossils:
Argentinian senator Magdalena Odarda expressed her opposition to Minera Cielo Azul's activities around the protected area of Bajo Santa Rosa y Bajo Trapalcó, located in the southern border of the Negro river in the Río Negro province.
Odarda asked the provincial ministry of environment to disclose information about the company's exploration activities. Such activities were confirmed in five sites which, she says, have paleontological significance due to the presence of dinosaur and marine reptile fossils. The senator also worries about the environmental effects of such activities.
Odarda says that residents of nearby Patagonian towns oppose the miner's operations, but their protest has been dismissed by both the local and the federal government.
Minera Cielo Azul, a subsidiary of Canadian Blue Sky Uranium , recently launched its exploration campaign at its Amarillo Grande project to prove up resources and outline economics. (mining.com Oct. 9, 2017)
CNEA is working to reactivate the Don Otto uranium project in Salta province. The Don Otto mine is being explored and evaluated to measure its economic feasibility. "Right now, we cannot say whether it will be reactivated or not," said Gian Franco Guidi, CNEA representative for northwestern Argentina. (BNamericas Nov. 27, 2007)
The re-opening of the Don Otto uranium mine will be formally initiated in early August 2007, when the minister of Planning, the governor of Salta, and the president of the national atomic energy commission (CNEA), sign a cooperation agreement. The mine will produce 30 tonnes of uranium per year. (Clarín Aug. 1, 2007)
Dioxitek S.A. , the industrial arm of Argentina's national atomic energy commission CNEA, and La Casualidad S.A., controlled by Salta province, are touching up the details of an agreement to operate jointly the Don Otto uranium mine. CNEA mined Don Otto between 1955 and 1981 but was forced to shut it down when uranium prices fell. "Now with Salta's offer to activate the deposit, we are rehabilitating it to move ahead with exploration and continue extracting what remained from previous mining," CNEA production manager Alberto Castillo said.

Development of stalled Itataia uranium/phosphate mine project to resume: After undergoing remodeling to meet environmental requirements, the project to explore [?] a uranium and phosphate mine in Ceará will be resumed by the Galvani fertilizer industry and the federal state-owned Indústrias Nucleares do Brasil (INB). The Santa Quitéria Consortium foresees that US $ 400 million will be invested in the Itataia project, 80% of which will be contributed by Galvani. The prospect is that production will start in three years. Conceived in 2009, the project was stalled in the process of obtaining environmental licenses at Ibama. (O Globo Sep. 29, 2020)

On July 8, 2014, INB announced that the public hearings, which were scheduled for July, were postponed at the request of IBAMA. The new dates will be announced soon.
EIA submitted for Itataia uranium/phosphate mine project:
On Sep. 19, 2013, the Santa Quitéria Consortium, consisting of INB and Galvani, filed with the Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA) the Environmental Impact Assessment report for the proposed mining of the phosphate and uranium deposit located in the municipality of Santa Quitéria (CE).
There are two processing plants planned for the mine: one for the production of phosphate fertilizers and dicalcium phosphate (animal feed), and the other for the production of yellow cake - uranium concentrate.
After validation by IBAMA, the environmental impact studies will be made available to the public, and public hearings will be held. The Consortium expects to get a preliminary license in the coming months (!). (INB Sep. 20, 2013)
Manifestation against Itataia uranium mine project: On July 25, 2012, a manifestation against the proposed Itataia uranium mine project was held by the movement "Articulação Antinuclear" (Joint Antinuclear) in the center of Santa Quitéria. The movement was formed by Cáritas Diocesana, MST, Grupo TRAMAS and Pastoral da Terra. The mine has not yet been opened, as state and federal authorities are still in disagreement on the authority for issuing the license. (Blog do Roseno Oliveira)
Uranium production at Santa Quitéria to start in 2014/2015: In spite of a low uranium concentration of nearly 0.1%, uranium extraction at Santa Quitéria could be cost efficient, as the measured resources are associated with phosphate and would produce 240,000 tons of the fertilizer component per year. Santa Quitéria will open in 2014/2015 and will be operated by the industrial group Galvani, that will extract the mineral for INB as part of a phosphate mining operation. The production would reach 1,500 tons per year in 2017. (Reuters Oct. 31, 2011)
INB selects private partner for mining of Santa Quitéria uranium/phosphate deposit:
On June 19, 2008, Brazil's state-run nuclear mining and fuel company INB chose local fertilizers producer Galvani as the private partner to mine phosphate and uranium at the Santa Quitéria reserve.
The INB, which has the monopoly rights on uranium mining in the country with the world's sixth biggest reserves of the radioactive metal, will get the uranium produced at the mine and Galvani will keep the phosphate, used as fertilizer.
Family-owned Galvani is Brazil's only integrated producer of phosphate fertilizers.
The Santa Quitéria prospect has a capacity to produce 240,000 tonnes of phosphate a year and 1,600 tonnes of uranium ore, the INB said in a statement. The private company will invest $350 million in the project.
Santa Quitéria in the northeastern Ceará state would churn out 800 tonnes of uranium in 2011 and then gradually boost output to 1,600 tonnes later, allowing Brazil to export over 1,000 tonnes of excess metal.
(Reuters June 19, 2008)
Brazilian fertilizer company Grupo Galvani will sign a 25-year contract with Brazil Nuclear Industries, or INB, to develop a uranium and phosphates mine at Itataia, the Estado news agency reported Monday (July 20, 2009). The contract, worth 800 million Brazilian reals ($420 million), will be signed next Thursday (July 23). The new unit will start operating in 2012 and will have initial output of 180,000 metric tons of phosphate and 1,200 tons a year of uranium concentrate. INB said when production eventually reaches 1,600 tons a year of concentrate, Brazil would be able to meet the demand for new nuclear plants planned. (Dow Jones July 20, 2009)

Uranium mine developer wins trust of local communities by "gently introducing socially supportive initiatives":
South America-focused project developer U3O8 on Tuesday (Nov. 20) said it had achieved significant successes in getting the local communities near to its Berlin uranium project, in Colombia, on board, even though the project is at the exploratory phase.
U3O8 president and CEO Richard Spencer told Mining Weekly Online the key to the project, which had been proven to host much more mineral potential than what was first thought, was to win the trust and recognition of the local communities of Berlin and San Diego, by "gently" introducing socially supportive initiatives. These included implementing educational initiatives, nutritional initiatives and methods to reduce its environmental footprint. "We have been assisting our local communities largely by facilitating the implementation of existing government initiatives. We are in a sense merely connecting the dots," he said in Toronto.
