    Mesothermal sheeted quartz veins

    By Miguel A Heredia

    During the 16th week of the year (April 19th to April 25th, 2021), at least 33 press releases were announced by companies working in Mexico and 5 news published by the media, with twelve informing on exploration results, nine disclosing deals and corporate issues, five commenting on Mexican issues, four announcing financial rounds, four reporting on resources and development, three communicating production results, and one discussing social issues.  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. 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. 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. The Mexican mining industry called on the environmental authorities to hold a dialogue to understand the reasons why the permits are being stopped. Representatives of the Mexican Mining industry asked the federal government to reactivate mineral concessions to increase investments in the sector.

    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

The drill plan for the next quarter is to drill test deeper part of the target. At La Soledad target, hole CDH-054 encountered 10.36 g/t Au and 81 g/t Ag over 4.88m, extending the mineralization further to the west and down dip. The company also informed that it has completed the soil sampling program within El Cometa and Reyes project areas.
    • Advance Gold Corp., announced drilling results from its Tabasquena project in Zacatecas. Hole AGT-23 intersected two zones, one of 0.63 g/t Au, 20 g/t Ag, 3.5% Pb,  and 8% Zn over 2m, and a second zone of 0.04 g/t Au, 6 g/t Ag, 0.18% Pb, and 1.1% Zn over 0.55m. Advance has drilled 23 holes to date and has outlined a 2,500m by 500m wide mineralized corridor and plans to carry out more mapping and geophysics to find the feeder system at  depth responsible for this widespread mineralization.
    • Zacatecas Silver Corp., reported that it has completed first pass geological and structural mapping, and sampling of the San Gil breccia Zone, located 2km southwest of the Veta Grande vein within its Zacatecas Silver project, Zacatecas.
