ON MEXICO ISSUE

  • Great Panther Mining Limited announced that it has begun the closure process at its Guanajuato facility. Great Panther issued a statement announcing the gradual closure of activities, due to not having the respective permit to expand tailings storage in the Jolula Dam, which is part of the mining complex. According to Great Panther, the permit was requested to the National Water Commission (CONAGUA) but so far it has not been authorized. For that reason the company cannot continue operating; but the operations will return, once they receive said authorization. The activities will continue solely for the care and maintenance of facilities. The mines that will be shut down are San Ignacio, the Guanajuato Complex and the Jolulaprocessing plant, located in the former Hacienda de Bustos, also known as ‘Cata’. Mine workers have expressed concern about the situation because when the activities stop in the mines in which they work they will lose their economic income. The precise data on how many employees will be affected by the situation is not yet available.

ON EXPLORATION

ON RESOURCES AND DEVELOPMENT

  • Chesapeake Gold Corp., provided an update of its Metates property in Durango, and announced technical plans for 2022. Management members and technical team of the company have been focused on improving the Metates ´project economics as a low cost, scalable mine, and the PEA showed positive results demonstrating an alternative mine plan with an approximately 90% decrease in development capital compared to an autoclave process flow sheet. The company plans to advance the metallurgical and technical work on Metates. In addition, the five-hole PQ diameter core drill program completed for metallurgical test work returned on average, a 19% increase in grade over the block model predicted grades. An overall increase in grade could have a significant impact on the PEA geological model and further improve project economics.

ON MEXICO ISSUE

  • AMLO reaffirmed this week his foolish and unfortunate policy of not granting more mining concessions in Mexico. He declared that mining companies were speculating in the financial market. López Obrador asserted that the existing mining concessions will be respected; however, his government will no longer give more, as many companies “cheated” and have not carried out exploitation tasks.
  • President Andrés Manuel López Obrador offered to meet the request of residents of San José del Progreso and collaborators of Compañía Minera Cuzcatlán, who asked him to avoid the closure of the San José mining unit, located in that Oaxacan municipality. The president was asked to avoid the loss of more than 1,200 direct jobs and around 8,000 indirect ones.
  • The current government has stopped the issuance of mining concessions and investment in Mexico. Parallel to the policy of null concessions, the president has presented a bill that intends to reserve strategic minerals such as lithium only for the State, denying any concession for their exploration, production or commercialization. Both their decisions not to grant a single concession in three years of government “and the promise not to do so in the entire six-year term”and to reserve strategic minerals for the State have been strongly criticized by specialists and representatives of the mining industry, to the point of warning that the future of the country is being“mortgaged.

ON DEALS AND CORPORATE ISSUES

  • Excellon Resources Inc., provided an update on litigation involving the Company’s subsidiary, San Pedro Resources SA de CV (San Pedro) in respect of the La Antigua mineral concession (Evolution property, Zacatecas). Excellon received an initial electronic notice last July that San Pedro’s appeal to the federal courts of Mexico in respect of the litigation was dismissed, despite the lack of evidence, facts or law to support this outcome. The Company has now received the formal written decision on the appeal which, based on initial legal review, appears to uphold the judgment granting the plaintiff an award of approximately USD $23M and is not subject to further legal appeal in Mexico.  Brendan Cahill, President and CEO of Excellon, stated that “The value ascribed in the judgment is impossible based on evidence, facts or law. Simply put, the maximum value realizable by the plaintiff from the agreement on La Antigua was USD $500K in the best-case scenario, yet the Miguel Auza Mine was shut down in 2008 almost immediately after operations commenced.”

ON SOCIAL RESPONSIBILITY

  • Alamos Gold Inc., has allocated MXP $400M in environmental investment at its la Yaqui Grande mining project in Sonora. The foregoing consists of environmental remediation works that will be carried out as areas of the mine are vacated, a different model from the traditional work that waits until the end of the useful life of a mine to carry out reclamation and closure activities. In La Yaqui Grande, it is contemplated to have constant reclamation of areas, placing the vegetal roof covering in layers and stages, which implied a special design and engineering to make it possible throughout the seven years of operation. The company will also acquire a treatment plant that will allow the water used in the operation to be recirculated, reducing its consumption. The design of “tepetateras or dumps” is different from the traditional ones and there is already a nursery for the reproduction of native plants of the region, which will supply the demand for the development of this environmental project.

The Mining and Exploration News in Mexico: Highlights on the Third Week of May, 2021.

Rich-silver banded quartz vein

By Miguel A Heredia

ON MEXICO ISSUES

  • Minera Penmont (Fresnillo plc) thanked the President of Mexico for his comments on the insecurity registered in Sonora. Two years ago, Minera Penmont denounced before state authorities the commission of various crimes, including the invasion of their property, perpetrated by a criminal group that claims to be part of the ejido. This group has absolutely no legal arguments and intends to take over the private property of the company to carry out mining exploitation actions outside the law, without the concession required for it, nor the corresponding environmental permits, using dangerous and controlled materials, directly affecting the Mexican State, the environment, the company and maintaining its criminal acts in the region.
  • Maria Luisa Albores, Head of the Ministry of Environmental and Natural Resources (SEMARNAT), traveled to Santa Rosalia to meets with businessmen and workers from El Boleo mining company.  She was entrusted with a consultation to find out the opinion of the population about the expansion of the environmental impact statement (MIA). Minera Boleo requested to expand the area of extraction, processing and shipment of copper minerals.
  • Plenary of the Guerrero State Congress approved recently the creation of the Mining Commission.  The president of the Political Coordination Board (Jucopo) of the local Congress, Alfredo Sánchez Esquivel pointed out that there is a real problem in the case of mining companies and the environment, for which the creation of this Commission was necessary. For his part, the state secretary of Promotion and Economic Development, Álvaro Burgos Barrera, considered the incorporation of a legislative commission to monitor the mining sector as highly relevant. He reported that in the current state administration headed by Héctor Astudillo Flores, governance allowed mining companies to invest approximately USD $2B in Guerrero.
  • Maria Luisa Albores, Head of the Ministry of Environmental and Natural Resources (SEMARNAT) made a series of unfortunate statements against the Mexican mining industry. She assured that the country’s mining activity has caused strong environmental effects, monopolizing water and causing social inequality. Her statements are full of biased and wrong information and caused immediately the strong reaction of different actors of the mining sector. Specialists of the sector declared that the view of the federal government has on mining is wrong. CAMIMEX has indicated that of the total water consumption in Mexico, 77% is used by agriculture; 14% is for public use; 5% to generate energy and 4% for industrial use and of the latter only 0.9% corresponds to milling. CAMIMEX also stated that 74% of the water used by this industry is recycled and, of that amount, 55% is continuously reused. In addition, the mining sector has 70 sewage treatment plants in the communities where it operates. There are dams that capture rainwater, which is given to the municipality, piped and sent to homes, when it is necessary. A large percentage of companies carry out social and human rights proceedings. They generate social and environmental programs. In 2019, mining companies allocated MXP $7,450M to actions in favor of the environment and MXP $1,756M to community development, in addition to the MXP $3,496M that were paid to the Mining Fund. Many companies have the largest plant nurseries in the country and have large animal rescue zoos that are delivered to the State. Mining is one of the industries that produces and plants the most trees, 6.6M million trees produced in the nurseries of mining companies; 2.93 million trees planted reforesting an area of more than 3,000 hectares in 2019. The Mexican mining industry is over-regulated and has to comply with seven environmental permits in the stage of exploration and nineteen environmental permits throughout the life of a mine. For the reasons stated above, the mining sector rejects the indications that point to that its activity does not respect the norms of protection of the environment and that it does not generate social welfare for the neighboring communities. That is why the sector unlocks the doors to the authorities with an open invitation to visit the operations and verify for themselves these realities of the mining sector and reliably inform the population.

ON EXPLORATION

ON MEXICO ISSUES

  • The Ministry of Economy issued an informative note to correct what President López Obrador said about the expansion of the operations of the mining company El Boleo that operates in Baja California Sur. The mining and metallurgical company is seeking an expansion in the surface of its operations and not a new concession as stated by the president. In July 2019, El Boleo requested an expansion of its environmental impact statement, in which it requested an expansion of its mine by 446 hectares contiguous to its current operation. They indicated that this is because the life of the main mine is running out and its mineral reserves are in this adjoining land. The statement indicates that the mining project began construction in December 2010, with an investment of USD $1,717M, and began production in 2015. The company produces copper, cobalt, zinc and manganese. Currently, the mining company employs 1,282 direct jobs (836 unionized and 446 trusted).
  • Fernando Alanís, president of the Mining Chamber of Mexico (Camimex), stated that the mining industry in Mexico paid MXP $30,374M in taxes during 2020. He also highlighted that those that refer to the fact that the industry pays little are myths, as he highlighted that around 10.6% of the Gross Domestic Product generated by the industry is destined to the payment of taxes, higher than the 7.6% of the manufacturing industry, or the 6.1% of the electricity sector. Fernando Alanis detailed that of the total taxes paid, MXP $24,205M are for Income Tax (ISR), while there are MXP $2,576M in surface rights and MXP $3,593M in new rights.
  • The Mining Chamber of Mexico (Camimex) stressed that mining is a tractor industry that, in addition to boosting the regional economy, supports the development of other economic activities. It drives construction with average annual investments of USD $5B a year. The same occurs with the transport of materials, by promoting the movement of 8.7M tons per year that travel 100.2million kilometers on the roads (78%) and railways (22%) of Mexico. It also boosts port activity, with the export and import of 474M tonnes of materials per year. In total, the transportation costs of mining companies in Mexico total USD $245M per year. Through the mining clusters (Zacatecas, Sonora, Chihuahua, Guerrero and Sinaloa) a local supply has been developed that amounts to 9,700 national supplier companies, 90% of which are small and medium-sized enterprises (SMEs). For Mexico, the mining industry is an outstanding generator of income, contributing 8.3% to the industrial GDP and 2.5% to the national GDP. It is also a large generator of jobs, with more than 379,000 direct jobs and almost 2 million indirect jobs.
  • The Mexican mining industry called on the environmental authorities to hold a dialogue to understand the reasons why the permits are being stopped and to work together to unlock authorizations for Environmental Impact Manifestations (MIAs) that are being held at the Ministry of the Environment and Natural Resources which have stopped several mining projects in the country. Mining in Mexico has a robust environmental legislation that is permanently addressed, among which the General Law of Equilibrium and the Environmental Protection, as well as seven Official Mexican Standards and the general regulation that exists for activity in protected natural areas in Mexico, among others.
  • Representatives of the Mexican Mining industry asked the federal government to reactivate mineral concessions to increase investments in the sector. No new mining concessions have been granted in the country since 2019 and the effects of this were reflected in a lower Foreign Direct Investment in the sector.
