ON MEXICO ISSUE
- The Ministry of Finance and Public Credit (SHCP) proposed to increase the mining rights in the Federal Income Law initiative released last November 15, 2024. SHCP stated that considering that minerals and substances are non-renewable public domain assets, it is proposed to increase the special and extraordinary rights on mining, raising rates from 7.5 to 8.5% and from 0.5 to 1.0%, respectively, as established in articles 268 and 270 of the Federal Law of Rights. The SHCP also argued that this adjustment responds to the upward trend in international metal prices, ensuring that those who benefit from these resources contribute equitably to the State. Currently, the SHCP charges a special fee of 7.5% on the net profit for the disposal or sale of the extractive activity, as well as an extraordinary fee on mining, corresponding to 0.5% on the income from the disposal of gold, silver and platinum. In addition, an additional mining fee per hectare is applied in concessions without exploration or exploitation. According to data from the Mexican Mining Chamber (CAMIMEX), fiscal contributions from the mining sector experienced a drop of 32.2% in 2023 compared to 2022, registering an amount of MXP $49,445.4M, “as a direct consequence of the closure of operations and the lack of growth in the sector.” In a breakdown, these contributions were as follows: Income Tax (MXP $37,888M), mining rights (MXP $2,876M), and new mining rights (MXP $8,682M).
- Despite all the contribution that the Mexican mining industry makes to the country’s economy, all analysts were surprised by the blow that is intended to be given to this industry in the proposal for the 2025 Economic Package that was presented last November 15, 2024. It is one of the most important industries in Mexico, since it is key to more than 70 productive sectors, and even many of the things we use daily could not be done without the intervention of mining. In Mexico, the mining industry is key to the development of the economy, there are 24 states that have a high vocation for mining, and more than 696 communities dedicated exclusively to that activity, where many legislators, authorities and businessmen from other branches should consider a trip to learn more about how they operate and, above all, the high degree of technology they use today, which makes them one of the industries with the greatest investments in both human capital and technology to make facilities safer. The Economic Package proposes an increase from 7.5% to 8.5% of the special right and from 0.5% to 1% the extraordinary right to mining activity, which threatens the competitiveness of an industry. Key that in recent years has already faced an adverse environment with the reforms to the Mining Law, the suspension of concessions and the lack of permits, and it seems that no one has realized the negative effects that would have on everyone.
- Mining will be key to meeting renewable goals in Mexico. Demand for critical minerals to produce electric cars, solar panels and wind turbines will quadruple by 2030. The objectives of companies operating in the country and the Mexican government to transition to greater consumption of renewable energies such as solar or wind will be impossible to meet if mining investment, responsible for producing critical minerals such as copper, lithium, silver, gold, nickel, manganese, cobalt, graphite, copper, zinc and rare earths necessary to manufacture electric vehicles, solar panels and wind turbines is not encouraged. In this sense, it is estimated that until 2030, the demand for critical minerals for clean energy technologies can grow up to four times. For some minerals, the growth can be much greater: the energy sector’s demand for lithium will grow more than 10 times by 2050 according to estimates by the Mexican Mining Chamber (CAMIMEX). With all of the above, the general director of CAMIMEX stated it is necessary for the authorities to carefully analyze the proposal that seeks to prohibit open pit mining, since this would impact not only the production of essential metals for the energy transition, but also would impact the social well-being of one million people in 690 communities that directly depend on mining activity. The Mexican mining industry set the goal of reducing its environmental footprint on a large scale while increasing its productivity, especially of strategic minerals for the energy transition, which is why by 2030 they will seek to achieve 46 percent of the country’s total energy consumption.
