Mexico’s Best Silver Drilling Intercepts, Second Quarter 2025

Fifteen companies released silver results from drilling programs in Mexico during the second quarter of 2025. The highest silver intercept was from Endeavour Silver’s Pitarrila project in Durango, with 247 m averaging 129 gpt Ag. The Ag-Pb-Zn mineralization at Pitarrilla developed in at least four veins, two dikes and as matrix replacement in a conglomerate (Manto Pitarrilla) overlying marine sedimentary rocks. “Drilling has confirmed that all structures originate below the marine sediments, extend through Manto Pitarrilla, and into the upper volcanics. These feeder structures remain open at depth”. The drill program is focused in further defining the geometry of the multiple, sub-vertical, mineralized feeder structures and the mineralized manto.

Two other deposits, Columba in Chihuahua and Don David in Oaxaca presented drill intercepts with grade*meter values greater than 5,000. These three deposits, along with Zacualpan, La Reyna, and Alamos Silver are intermediate sulfidation epithermal systems. The Cristina and Gran Pilar projects are also of intermediate sulfidation affinity, but probably distal to porphyry copper centers. Panuco in Sinaloa and (tentatively) La Colorada in Sonora straddle from low to intermediate sulfidation epithermal mineralization, and Santa Elena, Copalquin and El Cubo present low sulfidation characteristics of epithermal mineralization.  Finally, Campo Morado is a volcanogenic massive sulfides (VMS) deposit and El Limón a skarn system. Please note that the projects in the table below are scattered through Mexico from Sonora in the northwest to Guerrero and Oaxaca in the south.  

Mexico’s Best Gold Drilling Intercepts, Second Quarter 2025

Thirteen companies released results from drilling programs in Mexico during the first quarter of 2025. The highest gold intercept was at El Limón-Guajes Underground Sur deposit in Guerrero, with 10.30 m averaging 43.31 gpt Au, including a 2.90 m subinterval over 78 gpt Au. The drilling program was focused on extending the mine life at ELG underground “by identifying new zones of higher-grade mineralization, expanding resources within known areas, and replacing mined reserves”.

Since Q3 of 2024, deposits in the Guerrero Gold Belt, like ELG Underground, characterized by skarn mineralization have shown the highest gold intercepts on each quarter. Campo Morado, also in Guerrero, is part of a volcanogenic massive sulfide (VMS) system, and the only other deposit in the table below that is not of epithermal origin.  

Epithermal deposits compose the rest of the table.  Santa Elena, Copalquin and El Cubo are low sulfidation epithermal systems, Don David, Columba, La Reyna and Alamos Silver belong to the intermediate sulfidation category, while La Colorada (Sonora) and Panuco straddle these two categories. Gran Pilar and Cristina are intermediate sulfidation epithermal systems that are probably distal part of porphyry copper centers.

Summarizing, one deposit shows skarn mineralization, one more belongs to the VMS category, while eleven display low and/or intermediate sulfidation epithermal mineralization.

The Mining and Exploration News in Mexico: Highlights on the Third Week of November, 2024

Ankerite vein

By Miguel A Heredia

During the 47th week of the year (November 18th to November 24th 2024), at least 25 press releases were announced by companies working in Mexico, and 2 news published by the media, with six communicating production and financial results, six disclosing deals and corporate issues, six announcing financing rounds, five reporting resources and development of their properties, three commenting on Mexican issues, and one informing on exploration results.  ON MEXICO ISSUES, 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. 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. Mining will be key to meeting renewable goals in Mexico. Kootenay Silver, Guanajuato Silver, and Silver Storm reported the best drilling intercepts in Mexico on the third week of November, 2024.  ON EXPLORATION, In Chihuahua, Kootenay released results from 4 holes drilled at its Columba project.  ON MINING, Elemental Altusreported consolidated Q3, 2024 operating and financial results (Mercedes mine, Sonora).  Minera Alamos reported Q3, 2024 operating results from its Santana property in Sonora.

Sierra Mojada announced a significant breakthrough with the conditional lifting of a five-year blockade at the Sierra Mojada Mining Project in Coahuila. ON SOCIAL RESPONSIBILITY,  no relevant news.

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.
  • Kootenay Silver Inc., Guanajuato Silver Company Ltd., and Silver Storm Mining Ltd., reported the best drilling intercepts in Mexico on the third week of November, 2024. Details are shown in the table below:
