Protests against uranium mining held across Argentina

At the occasion of the Marcha Plurinacional Antinuclear 2022, protests were also held against uranium mining in various locations across Argentina on April 23, 2022:
In San Miguel de Tucumán, in front of the historic house, the environmental group Pro-Eco Tucumán displayed a poster with the legend: "Enough of nuclear energy! neither plants nor uranium mine", candles were also lit in commemoration of the victims of the Chernobyl accident.
In the city of La Rioja, in the Plaza 25 de Mayo, the Capital Riojan Assembly organized several musical events. "La Rioja says no uranium" warned the posters. It happens that about 20 kilometers from the place, the National Atomic Energy Commission is preparing an exploratory drilling campaign for uranium mining in the Quebrada Alipán.
In Valcheta, province of Río Negro, the Curru Leufu Assemblies met, the T-shirts with the legend "Valcheta free of uranium" are related to the Ivana mine, in the advanced exploration phase, whose operation will require excavating more than 13 thousand tons of materials per day. Ivana is part of the Amarillo Grande project, of the Canadian multinational Blue Sky Uranium, which advertises 500,000 hectares of mining properties in Argentine Patagonia, while maintaining an aggressive exploratory drilling program.
The Antinuclear Movement of Chubut suspended an event in the pedestrian street Gazin due to bad weather. In this province, the Canadian Consolidated Uranium recently announced that it will start a new exploration program in Laguna Salada. (Movimiento Antinuclear de la República Argentina Apr. 24, 2022)

International Consolidated Uranium Inc. to acquire Laguna Salada Uranium and Vanadium project: On Dec. 14, 2020, International Consolidated Uranium Inc. (CUR) announced that it has entered into an option agreement with U3O8 Corp. providing CUR with the option to acquire a 100%, undivided interest, in the Laguna Salada Project.

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".
The PEA is based on a $60 per pound uranium (U3O8) price and $5.50/lb for vanadium (V2O5).

> Calculate Mine Feasibility

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)


Areva considers construction of uranium mill in southern Argentina

Areva NC is investigating options regarding uranium resources in southern Argentina and is in cooperation with various owners including Urex Energy Corporation to support a potential central process facility. A minimum mineable uranium reserve necessary to support such a process facility is estimated at 22 million pounds of eU3O8 [8,462 t U]. The concept is that the mining of a number of satellite uranium ore bodies, controlled by different owners, would provide uranium ore feed to the central milling facility. Urex Energy Corp. is conducting uranium exploration in the Chubut Province adjacent to Comisión Nacional de Energía Atómica's (CNEA) Cerro Solo uranium deposit. (Urex Energy Corporation March 24, 2009; on Feb. 10, 2010, Urex Energy Corp. reported that it has sold its Argentine subsidiary; and on July 22, 2010, the company changed its name to Mustang Geothermal Corp.)

Demonstrations against zoning for gold and uranium mining in Chubut: As happens on the 4th of each month, the Assembly of Neighbors Self-convened by No a la Mina , organized the traditional concentration and march through the streets of Esquel against the mega-mining enterprises that intend to settle in the region and in the province.
"They come for the Christmas silver, the uranium from Cerro Solo and the gold from Esquel." (EQS Notas Oct. 4, 2021)

CNEA's strategy for restart of Cerro Solo mine still unclear: 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)

New developer sought for Cerro Solo uranium mining project: 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)

Opposition against uranium mining in Jujuy: Los Vecinos Autoconvocados de Tilcara y Juella


Quebadra de Humahuaca uranium exploration project

Residents file appeal to Supreme Court to prevent mining in UNESCO World Heritage area Quebrada de Humahuaca: The organisation Los Vecinos Autoconvocados de Tilcara y Juella presents today a special federal appeal to the Supreme Court of Justice, asking for the cancellation of prospecting and exploration permits in the Quebrada de Humahuaca. On March 21, 2014, the Superior Court of Jujuy (TSJ) had rejected the request of the residents of Tilcara and Juella to stop open-pit mining in the Quebrada de Humahuaca.
Last year, Uranio del Sur SA sold its properties to Electrum Resources SA [100% owned by ECR Minerals plc ]. (Jujuy al Día, Apr. 23, 2014)

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.

On this issue, through a communiqué, the neighbors reaffirmed that there is no social license for uranium mining "since then we have effectively blocked the vehicles of the National Atomic Energy Commission (CNEA) that intends to move forward with the uranium mining project located in Las cañas, Quebrada de Alipán.
To this day we continue to cut the road, reaffirming the defense of the right to life, to common goods such as water, to production and to a healthy environment for future generations. [...]" (El Independiente, Nov. 29, 2021)

Protestors against uranium mining project block highway in La Rioja: Residents of La Rioja today (Mar. 17) blocked the national route 38 to protest against the water shortage, for which they blame the mining operations being conducted a few kilometers away by the National Atomic Energy Commission (CNEA).
Residents say the lack of water in the region began with the start of 11 projects searching for uranium for the official body about 15 kilometers from the capital of La Rioja, the most populous city in the province. The water shortage began in August last year and worsened during the summer; it coincides with the rise of the large uranium mining project in Quebrada de Alipán, according to the protestors. (Los Andes Mar. 17, 2014)

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.

Provincial Supreme Court concurs with Superior Court that environmental protection lawsuit filed against Amarillo Grande uranium mine project is inadmissible: On January 12, 2022, Blue Sky Uranium Corp. announced that the lawsuit introduced before the Supreme Court of the Province of Río Negro and a subsequent appeal filed before the same Court against the Company have been dismissed.
Throughout this process, the Company's exploration operations proceeded unimpeded. Blue Sky is continuing with its drilling plans, surface exploration initiatives, advanced metallurgical studies, and environmental baseline studies as previously announced.

Superior Court declares environmental protection lawsuit filed against Amarillo Grande uranium mine project inadmissible: A judge of the Superior Court of Justice of Río Negro declared the formal inadmissibility of the amparo filed by 13 people against Minera Cielo Azul SA and the government of Río Negro, in order to order them to refrain from executing or continuing the activities of the company - Argentine subsidiary of the Canadian Blue Sky Uranium CO - within the framework of the Amarillo Grande uranium and vanadium extraction project ("Anit", "Santa Bárbara", "Ivana" properties) to be developed near the towns of Valcheta and Lamarque. (Más Río Negro Nov. 1, 2021)

On Sep. 16, 2021, Blue Sky Uranium Corp. announced the company's wholly-owned Argentine subsidiary, Minera Cielo Azul S.A. ("MCA"), has received notice that it has been named in a lawsuit by anti-mining, environmental activists in Argentina who are asserting environmental protection rights, among other arguments ("Amparo" in Spanish) against the Amarillo Grande project, comprised of Ivana, Anit and Santa Barbara Projects. The lawsuit was introduced before the Supreme Court of the Province of Río Negro, Argentina. The defendants in this "Amparo" action are MCA and the Government of Río Negro.

Environmentalists from Río Negro presented in recent days a Collective Environmental Protection Appeal before the Superior Court of Justice, against uranium mining in the province.
"We ask for the cessation of the actions they are developing and we ask that uranium mining cannot be carried out, due to a lot of environmental consequences for health," they explained. (Noticias Río Negro Mar. 22, 2021)

Tehuelche Mapuche Parliament rejects uranium mining proposal at Ivana deposit of Amarillo Grande project The Coordinating Committee of the Mapuche Tehuelche Parliament reminded that the uranium exploitation project Mina Ivana "is beginning its development 25 km from Valcheta, within an area of 118,000 hectares that the government of Río Negro has ceded for exploration and exploitation to the company Blue Sky Uranium Corporation". This is a Canadian company which, according to corporate information, is dedicated to "the acquisition, evaluation and exploration of uranium properties in Canada and Argentina".
The Mapuche Tehuelche statement stated that "Amarillo Grande is the name of the integral project and the government has the Preliminary Economic Evaluation Report, but has not made us participate and has not informed our community organization, which has to review the environmental impact report but fundamentally, has to develop a cultural impact report, which is a right that we have as communities to determine the possibility of this project".
On the governmental side, the organization pointed out several shortcomings. "The Provincial Mining Evaluation Council (CoPEAM), created by Law 4738/11 should have indigenous representation so that our position is heard." However, "it does not comply with the participation and consultation with the communities and dispersed settlers, contemplated within Law 2287 as subjects of indigenous law assimilated to the communities and therefore, ILO Convention 169 applies".
For the Coordinadora Mapuche Tehuelche, "the development of this uranium and vanadium project contains an extra danger and that is that they want to install the plant in a flood zone with a tailings pond (water contaminated with radioactive waste) 500 meters from the Tres Picos lagoon. This project is compatible with death and its development will have devastating consequences for life. Any incident will be remediated in thousands of years and the radioactive waste will also be exposed for thousands of years". (Comité por los Derechos Humanos en América Latina, Jan. 10, 2020)

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)

Bolivia rules out uranium production

Bolivia's government has ruled out pursuing uranium production after consultations with German and French experts and decided to focus instead on the industrial development of its vast lithium reserves. "The uranium industry is practically in recession because it generates lots of toxic waste" that is difficult to eliminate, the president of state-owned mining company Comibol, Marcelino Quispe, was quoted as saying by state-run news agency ABI.
Since the peaceful nuclear program envisioned by President Evo Morales' administration does not require large quantities of uranium, the Andean nation will instead buy that metal from France, Canada and Australia. The country's last uranium mine closed in 1984, Quispe said. (Fox News Nov. 12, 2015)

IAEA offers aid for Bolivia to exploit uranium

The United Nations announced on Mar. 27, 2009, its disposition to cooperate with Bolivia on the exploration and exploitation of uranium mines.
Bolivia has uranium deposits, but the government has classified the information as "reserved." According to reports from the Canadian company Mega Uranium - Intrepid Mines , the uranium mine is situated in the plateau.
Meanwhile, the National Service of Geology and Mining (Sergeotecmin ) identified 11 locations with uranium in natural state in the district of Cotaje between the towns of Huari in Oruro and Sevaruyo in the border area between both departments and Mulato River in Potosí. But technical reports say that those are not uranium concentrated deposits, but "small points"; and the amount of the reserves are unknown due to lack of investment in the quantification work.

EIS for Itataia uranium/phosphate mine project accepted by IBAMA for analysis: Last Friday (03/18), the Brazilian Institute for the Environment and Renewable Natural Resources - Ibama accepted the Environmental Impact Study and the Environmental Impact Report (EIA/RIMA) of the Santa Quitéria Project. This is an important step in the licensing process, as it checks whether the content of the document complies with the Term of Reference stipulated by the agency and, therefore, will be submitted to technical analysis.
The forecast production is 1.05 million tons/year of phosphate fertilizers, 220 thousand tons/year of dicalcium phosphate (for animal feed) and 2,300 tons/year of uranium concentrate. (INB Mar. 23, 2022)

Brazil accelerates licensing of Itataia uranium/phosphate mine project: One of the projects listed in the National Fertilizer Plan (PNF) - which the government launched on Friday (Mar. 11) to reduce Brazil's dependence in the sector - is the exploitation of the Itataia deposit, located in the municipality of Santa Quitéria, in Ceará, about 210 km from Fortaleza. Phosphate, which can be used as an input for agribusiness, and uranium, which is used as fuel for nuclear plants, are found in the reserve.
For this reason, besides being part of the PNF, the Santa Quitéria project, as it is called, is also eligible for the Pro-Strategic Minerals Policy, of the Investment Partnerships Program (PPI). A consortium formed by the state-owned Nuclear Industries of Brazil (INB) and the Bahia fertilizer manufacturer Galvani in 2011 is qualified to explore the deposit, located in the domains of the Itataia Farm, which covers 4,042 hectares.
For over ten years, the consortium has been working on the environmental licensing of the project with the Brazilian Institute for the Environment and Renewable Natural Resources (Ibama) , under criticism from local residents' groups and social movements. The expectation is that the approval of the Environmental Impact Report (Rima), submitted in 2017, will be accelerated with the start of the PNF - which provides, among other measures, the debureaucratization of licensing processes for mining exploration.
According to Galvani, after this stage, the start of construction should occur between the end of this year and the beginning of 2023, so that the operation itself can begin in the second half of 2024 or the first half of 2025. Winner of a bidding process opened by INB, the company is responsible for the investments and for developing the processes, engineering, studies for environmental licensing, construction, and assembly of the enterprise.
Phosphate is predominant in the site, corresponding to about 90% of the deposit. According to INB, approximately 8.9 million tons of the mineral and 80 thousand tons of uranium are available for exploitation over the 20-year life of the enterprise.
In all, investments of R$ 2.3 billion [US$ 452 million] are foreseen by the consortium in a complex that will perform both the mining and the processing of the ore composed of phosphate and uranium and known as colophanite. At its maximum capacity, the mine, which will be mined in the open pit, is expected to produce 1.05 million tons of phosphate fertilizers annually, in addition to 220,000 tons of bicalcium phosphate, used in animal nutrition. (Gazeta do Povo Mar. 14, 2022)

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)

INB hopes to get uranium export clearance for Santa Quitéria phosphate and uranium mining project to become viable

Brazil's state-run nuclear mining and fuel company INB hopes to get government clearance to start exporting uranium as part of a plan to quadruple production by 2011 and expand prospecting. Luis Felipe da Silva, INB president's special aide for new projects, said the Santa Quitéria phosphate and uranium mining project, which would involve a private partner to mine phosphates, hinged on the liberalization of exports. So far, Brazil's laws make uranium mining and trade a state monopoly and do not permit exports.
Santa Quitéria in the northeastern Ceará state would churn out 800 tonnes of uranium in 2011 and 1,200 tonnes later on, allowing Brazil to export over 1,000 tonnes of excess metal. Guilherme Camargo, a director at the Brazilian Nuclear Energy Association (ABEN) industry lobby, warned that without the green light for exports Santa Quitéria was doomed to fail.

In Guatemala, uranium prospection and/or exploration is being performed by Pathfinder Resources Ltd. , Gold-Ore Resources Ltd. , Santoy Resources Ltd.


Ministry says it has not issued any exploration licenses for uranium, so no uranium deposits exist: "In view of publications and comments made in the Congress of the Republic and in press articles regarding the alleged presence of the mineral uranium in the soil of the department of Izabal, it is necessary to inform that in Guatemala there are no exploration or exploitation licenses for said element; that the same is not geologically associated to the presence of minerals of the nickel family; and that the existence of a deposit or deposit of said mineral in this country has never been proven.
The possibility of the presence of commercially exploitable quantities of uranium in the Guatemalan territory has not been scientifically proven. Studies carried out in past decades found simple anomalies, with no feasibility of economic exploitation; and they were found in the national volcanic belt, not in the nickel laterites.
What is geologically proven is that uranium is not a mineral that is associated to the presence of organic materials [?!], but it comes from igneous rocks, present in the earth's crust. Therefore, geologically it is possible to affirm that in the nickel mines there is no uranium present in quantities that represent the possibility of its profitable economic exploitation.
Finally, it should be clarified to the public opinion that in the case of the mining license "Sechol Mining Extraction Project", the authorization issued by this institution is to exploit only the minerals nickel, cobalt, iron, chromium and magnesium, also, that no authority of the Ministry of Energy and Mines has had any communication with any investor related to the possibility of uranium exploitation in Guatemala.

Puno cave paintings at risk from mining concessions

Between the districts of Macusani and Corani, located at 4,500 meters above sea level in the province of Carabaya in the department of Puno and with temperatures of 10 degrees below zero, awaits the richest wealth of cave paintings from the time of the hunters, along with an extensive forest of rocks and peasant communities dedicated to the breeding of alpacas that position the region as the alpaca capital of the world for the quality of its fiber.
In the same area, declared a cultural heritage site more than fifteen years ago and recognized as such worldwide, a long list of mining companies seek to extract uranium and lithium, according to Austrian agronomist and rock art researcher Rainer Hostnig.
"Mining activity would bring a harmful effect on the area. Large-scale open-pit mining could generate the loss of pastures, wetlands and other water sources, which would also affect the peasant communities of both districts dedicated to alpaca breeding", warns researcher Hostnig.

Macusani Yellowcake suspends hydrogeological studies at Falchani lithium/uranium project due to protests in Puno: In the midst of the escalation of conflicts in southern Peru, Macusani Yellowcake [subsidiary of American Lithium Corp.] suspended its hydrogeological studies in the Falchani lithium project (Puno). This measure was taken to avoid possible tensions between the local peasant patrols, with whom they have a direct relationship, and the provincial ones. (Gestión Jan. 11, 2023)

Lithium can be mined at Falchani deposit without touching uranium - therefore no need for radioactive minerals legislation, company claims: Macusani Yellowcake says its Falchani lithium project is not associated with the uranium that lies everywhere on the Macusani plateau. However, the Ministry of Energy and Mines (Minem) continues to maintain that the project will be difficult to develop because its operator, Macusani Yellowcake, has failed to discover uranium-free lithium.
"The mining company in charge of these concessions (Macusani Yellowcake) has not recently explored. So, the lithium we have is still a lithium that is associated with uranium," said the head of the sector, Jaime Gálvez, in conversation with the press.
"Falchani's lithium is clean [of uranium]. The thing is that we (Macusani Yellowcake) appeared to explore uranium in 2007, but we found a lithium deposit," explains Ulises Solís, general manager of the Canadian mining company.
He details that both projects are located in separate areas: the lithium project in the Chacaconiza district, while the uranium project is located in the Corani and Isivilla districts.
For this reason, he notes that "there is no need for radioactive minerals legislation," such as the one that Minem has been preparing for more than a year with the help of the United States Agency for International Development (USAID), and of which nothing is known yet. (El Comercio Mar. 16, 2021)

Positive Preliminary Economic Assessment announced for Macusani Yellowcake Inc.'s uranium deposits in Peru: On Dec. 5, 2013, Macusani Yellowcake Inc. announced the results of a Preliminary Economic Assessment ("PEA") for its uranium properties located on the Macusani Plateau in the Puno District of southeastern Peru. "The results from the PEA demonstrate that the Project has the potential to become a large, low-cost uranium mining operation."
Potentially economic material for the Project will initially come from multiple target deposits including Colibri 2 & 3/Tupuramani, Chilcuno Chico, Quebrada Blanca, Corachapi and Triunfador 1. Conventional open pit and underground mining methods are proposed. The PEA contemplates the construction of a mine and centralized processing facility operating over a 10 year mine life at a throughput of approximately 23,400 tonnes per day. A heap leach would be used to extract uranium into an acidic aqueous leach solution.

On April 26, 2010, Macusani Yellowcake Inc. announced the completion of a positive Preliminary Economic Assessment (PEA) for the Colibri II/III uranium deposit located on the Macusani Plateau, Puno in southeastern Peru.

Uruguay seeks public-private partnerships for development of uranium mining

ANCAP (Uruguay's state oil company) is making contacts with various mining companies installed in Uruguay to join in the event that technical studies confirm the presence of uranium in the ground. Speaking to El Observador, ANCAP's manager of exploration and production, Héctor de Santa Ana, revealed that there are mining companies who are interested in the commercial exploitation of uranium. However, the Mining Code prevents private exploitation of any energy resource, reserving them for ANCAP. For that reason, the agency is developing a wide variety of contracts to "associate" with private companies in case chemical analysis of soil detects a potential for profitable uranium mining.

Uranium development in Uruguay on hold

The Uruguayan government's plans to call for bids to explore uranium in the country have been put on hold, the head of the country's mining and geology department Dinamige, Pier Rossi, told BNamericas. "From what I understand, there were some companies that presented development projects but this initiative has been put on hold," Rossi said. The plans changed when modifications were made to the mining code and uranium became a class one mineral, according to Rossi. A class one mineral becomes state property once it is mined, whereas other minerals belong to whoever mines them. The use of uranium as an energy source is now under the management of state oil company Ancap , which is responsible for supervising energy initiatives, but the entity has not announced any plans for uranium development. In 2009, Dinamige announced that the bidding rules for uranium exploration were almost ready. (Business News Americas Nov. 16, 2011)

Uruguay considers launching bid for uranium exploration

Authorities at Uruguay's national mining and geology department Dinamige are considering launching a bid for uranium exploration, Dinamige head Luis Ferrari told BNamericas. The entity was unprepared for the degree of interest shown by a number of companies in exploring there and is now considering launching a bid in areas of interest. The official said interested parties have until mid-September 2007 to present proposals. Uruguayan mining law establishes that minerals with energy purposes receive special treatment and the state holds exclusive mining rights. As such, bidding processes are necessary for third-party exploratory studies, the official said. (Business News Americas July 30, 2007)

Iran assists Venezuela with search for uranium deposits

Iran is helping Venezuela to detect uranium deposits and initial evaluations suggest reserves are significant, the South American government said Friday (Sep. 25) -- the same day world leaders criticized the Islamic republic of secretly building a uranium-enrichment plant that could be used to make an atomic bomb. Mining Minister Rodolfo Sanz said Iran has been assisting Venezuela with geophysical survey flights and geochemical analysis of the deposits, and that evaluations "indicate the existence of uranium in western parts of the country and in Santa Elena de Uairén," in southeastern Bolívar state.
