ON MEXICO ISSUE

  • Jaime Gutiérrez Núñez, President of the Mexican Mining Chamber (CAMIMEX) stated that political risk causes a reduction in the mining investment in Mexico.  The lack of legal certainty and a complex environment for obtaining licenses and concessions are holding back investment in the Mexico’s mining sector, despite the rise in metal prices. Actual spending was USD $4.25B, 15.6% below the original estimates, according to CAMIMEX. The figure is lower than the USD $4.67B in 2019 and is well below the high of USD $8.42B in 2012.  Due to the lack of mining concessions, investment opportunities of USD $25B are lost in the country. Currently, there are 29 applications detained in the Secretary of the Environment and Natural Resources (SEMARNAT) and 34 at the National Water Commission (CONAGUA). With an adequate legal framework and adequate incentives, mining activity could generate 50 thousand additional direct jobs and more than MXP $25B a year in addition to those already paid by mining. “The statements of the President (against mining), not granting mining concessions, denying access to information, making procedures increasingly slow, although the terms are established in the law, and the lack of personnel in the Mining Directorate General  have impeded the advancement of mining projects in the country”.
  • Alfonso Durazo, governor of Sonora State, declared that the Mining Fund program could be back in the state after it was frozen for a little more than three years by the Federal government. If the Mining Fund is back, the injection of resources into the entity in this 2022 will be greater than MXP $1,000M, same that will benefit the mining towns and incidentally will give a good respite to state public finances.

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

  • Aztec Minerals Corp., and its JV partner Kootenay Silver Inc., commenced a 5,000m RC drilling program to test four main targets at the Cervantes project in Sonora. “The primary objectives of the drilling program are to better define the near surface, oxide gold potential of the porphyry gold oxide cap at California, evaluate the potential for deeper copper-gold porphyry sulfide mineralization underlying the oxide cap, test for north and west extensions of the California mineralization at California North and Jasper, and assess the breccia potential of Purisima East”.
  • Barksdale Resources Corp., announced the completion of the Phase I, 5,000m drilling program conducted at the Cerro Verde Zone within its San Javier project.

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.

  • 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 MEXICO ISSUES

  • Governors of Guerrero, Chihuahua, and Durango showed their support for the mining industry during the inauguration of the XXXIV International Mining Convention in Acapulco because it represents a lever for the economic development of the country. They promised to respect the rule of law to promote the investment in the sector that generates jobs and benefits to the communities where it operates.
  • Jaime Gutiérrez Núñez, president of The Mining Chamber of Mexico Camimex stated that the suspension of new mining concessions as well as the effects of the possible approval of the electricity reform and the heavy tax burden is generating strong uncertainty in the mining sector in Mexico.
  • Tonatiuh Herrera Gutiérrez, Undersecretary of Promotion and Environmental Regulations of the Secretariat of the Environment and Natural Resources (SEMARNAT), warned that the agency will keep consultations on land use for mining activity. Jaime Gutierrez Núñez, president of CAMIMEX responded that the companies affiliated to said organization do not oppose to the consultations on land use for mining activity, but emphasized that times should be established for conducting such consultations. Likewise, the Director of CAMIMEX, Karen Flores Arredondo stressed that “the rules of the game” must be clear and based on the General Consultation Law.
  • Miguel Ángel Riquelme Solís, governor of Coahuila State and Grupo Mexico signed an agreement to regularize properties in the Carboniferous Region of Coahuila. This regulation agreement represents legal certainty for more than 400 families in the Carboniferous Region.
  • The Mining Commission of the State Congress was installed, chaired by the deputy for Morena, Próspero Valenzuela Muñer to meet the demands and open a space for dialogue with the mining sector in Sonora. In that sense, he mentioned that it is important that said commission lays the foundations for the detonation of economic development and well-being in Sonora, taking advantage of the fact that this entity constitutes one of the main mining states in the country.
  • Octavio Alvídrez, CEO of the Mexican precious metals Fresnillo plc stated that mining in Mexico currently has an “unfavorable” environment due to recent government policies. President Andrés Manuel López Obrador has been criticized by the mining industry for his policy of not granting new concessions, as well as for what he has described as unprecedented regulatory delays. The president further fueled industry concerns by recently proposing to Congress a controversial energy constitutional reform that rejects concessions for Lithium.
  • The Mexican Geological Service (SGM) will invest MXP $55.2M between this year and the next in the exploration of lithium  with a view to finding an economically viable deposit, informed its director, Flor de María Harp. Exploration work will be carried out in 52 areas during 2021 and in another 30 in 2022. She explained that the country needs hard data so that we are not talking about what we believe, imagine or assume, but about data that have a technical basis. The official insisted that in Mexico expectations have been generated around lithium that is not real, because there is still no hard data on the potential of the mineral.
  • Karen Flores, director of the Mining Chamber of Mexico (CAMIMEX) stressed that due to lack of mineral concessions the mining industry in Mexico loses USD $25B with the consequent absence of jobs generation and the fiscal contribution. So far in this six-year term, no new concessions have been granted, in addition to the fact that there are procedures stopped that have also impacted on the continuity of some mining projects.
  • Sergio Almazán, president of the Association of Mining Engineers, Metallurgists and Geologists of Mexico (AIMMGM), highlighted the relevance of the mining industry for the country’s economy in the inauguration of the XXXIV International Mining Convention in Acapulco. CAMIMEX, in its 2020 report stated that the industry currently generates around 408,000 direct jobs, plus almost 2 million indirect jobs. It means that many Mexican families literally live from mining. Mining activity stands out as the fifth earner of foreign currency to the country. He also highlighted that Mexican mining is a formal, modern, sustainable, safe, fiscally responsible industry, with competitive salaries and high quality standards.

ON EXPLORATION

  • One World Lithium Inc., announced that drill hole # 4 collared at its Salar del Diablo project in Baja California, reached a total depth of 518m and that sampling has been completed between 331 to 338m and a second zone between 460 to 518m. Samples have been submitted to the lab and results will be released once are received.
  • Benjamin Hill Mining Corp., announced that it has completed the location of 15 drill holes for the upcoming inaugural drill program at its Benjamin Hill project in Sonora. The goal of the drill program is to better understand the behavior of the mineralization at depth and drill-test the continuity of high-grade mineralization structures that are thought to be open down dip and on strike.
