ON MEXICO ISSUES

  • Silver mining investments in Mexico boosted by a production shortfall and ecological demand. Mining companies in Mexico are investing in growth on the outlook of silver demand surpassing production in the transition to the abandonment of fossil fuels. Silver use is augmenting in the construction of photovoltaic panels, and is also a key component in the construction of electric vehicles. Silver production has fallen from 899 M Oz in 2016 to 784 M Oz in 2020, although a rebound from the pandemic is estimated at 848 M Oz for 2021. Mexico was the largest silver producer in the world in 2020, with 180 M Oz.

    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.

    ON EXPLORATION
