According to financial analysts, The 10 largest publicly traded mining companies have registered a gain of USD $528.63 B in the last year. This increase in value is driven by a historic rally in the prices of gold and silver, and sustained demand for copper for the energy transition. The gold price has rebounded by more than 20% so far this year, and the silver price by around 63% in 2026. The 10 largest mining companies reached a combined market capitalization of USD $1.33 trillion as of January 28, 2026. Compared to January 2025, the same companies had a combined market value of USD $678.57B, representing an increase of 96.47% or USD $654.6B. Included in this list is Southern Copper Corporation, one of the world´s largest integrated copper producers, with mail operations in Peru and Mexico, which added USD $88.37B to its market capitalization. In January, 2026, the mining company´s value is projected at USD $162.3B.

ON EXPLORATION

Sierra Madre Gold and Silver Ltd., commenced a USD $3.5M exploration program at the East District of its Guitarra mine in Estado de Mexico. The East District includes historic mines and over 39km of mapped structures. The program aims to systematically map, survey, and analyze historic mine workings and structures to identify promising drill targets. After completing detailed surface mapping and structural analysis over approximately nine months, the company plans to conduct a 20,000 to 25,000m drill campaign over 12 to 18 months to evaluate the economic potential of identified targets. The funding for this phase is secured through a recent private placement, with the goal of unlocking additional resources in a historically under-explored area.
Tocvan Ventures Corp. announced the discovery of two new gold and silver targets within the North Alteration Zone with historic underground workings at their Gran Pilar project in Sonora. These targets are based on historic underground workings that indicate the presence of mineralized structures. Target 1 is located 700m west of existing drill targets and features approximately a 60-meter exposed section of underground adits and shafts with silicified vein breccia and intense phyllic alteration. Target 2 is situated 700m north of previous high-grade samples and includes a 50m section of historic shafts and waste dumps with argillic alteration and quartz veining. Both targets align with previous high-grade surface sample results, such as assays up to 3.2 g/t Au and 1,225 g/t Ag, suggesting significant mineralization potential. These discoveries validate the exploration model and provide new avenues for drilling and resource delineation, expanding the mineralized footprint in the North Block.

ON MEXICO ISSUES

Mining companies listed on the Mexican Stock Exchange (BMV) and Wall Street are expected to gain more than USD $250 billion in market value so far in 2025. On the BMV, Grupo México, the world’s fourth-largest copper producer, is the mining company that has gained the most (USD $22.928 billion) in market value, totaling USD $59.98 billion. Its shares are up 42.89 % to MXP $141.36 this year. The company owned by Grupo BAL, Industrias Peñoles, gained USD $12.182 billion in market capitalization, reaching USD $124.533 billion. Its shares rose 199.51 % to MXP $797.29. Meanwhile, Minera Frisco added USD $2.182 billion and is worth USD $3.176 billion. Its shares increased 181.87 % to MXP $9.64 for the year. Fresnillo, a Peñoles subsidiary listed on the London Stock Exchange, earned USD $17.74 billion and has a total market value of USD $23.59 billion. Its shares rose 281 % to 2.36 pounds sterling, according to companiesmarketcap. The firms’ gains are driven by the price of gold, which reached a new all-time high above USD $4,000 per ounce, “benefiting from the weakness of the dollar, central bank purchases, and expectations of additional rate cuts in the United States.

Heliostar Metals Ltd., and Torex Gold Resources Inc., reported the best drilling intercepts in Mexico on the second week of October, 2025. Details are shown in the table below:

ON EXPLORATION

Tocvan Ventures Corp., reported the early results from a drone magnetic survey at its Gran Pilar Gold-Silver project in Sonora, and announced the discovery of a new target with historic underground workings in the North Alteration Zone.. The survey uncovered a major structural complex in the South Block, spanning approximately 2 by 2.5km. This complex exhibits magnetic signatures suggestive of magmatic activity and correlates strongly with past sampling up to 21.2 g/t Au and over 2,000 g/t Ag. These findings highlight new and expanded exploration targets, especially near areas with historical placer mining, and support the potential for deeper mineralization. The survey results validate geological models and provide a clear pathway for upcoming drill programs to evaluate the project’s mineral resources further. Tocvan also reported that it uncovered a new mineralized zone with 80m exposed section of old underground workings within the North Alteration Zone, with waste piles of silicified vein breccia material, and intense phyllic and argillic alteration. This zone features historic underground workings and extensive alteration patterns of approximately 3.2km long, indicating significant mineralization potential. Initial sampling has returned promising high-grade results for gold and silver, and the company plans to conduct further trenching, detailed mapping, and drilling to explore this largely underexplored area.
Pacifica Silver Corp., identified new high-priority drill targets based on assay results from 325 surface rock chips samples collected at its Claudia project in Durango. These samples yielded results up to 23.6 g/t Au and 480 g/t Ag confirming that the high-grade Au-Ag mineralization at the property is more extensive than previously recognized and may extend further south for another 300m towards the Mina de Oro vein system. Rock chips sample highlights include 111.2 g/t Au and 17 g/t Ag; 7.15 g/t Au and 143 g/t Ag; 2.74 g/t Au and 404 g/t Ag; 3.33 g/t Au and 311 g/t Ag; 2.03 g/t Au and 312 g/t Ag; 0.39 g/t Au and 408 g/t Ag; 1.83 g/t Au and 230 g/t Ag; and 2.19 g/t Au and 190 g/t Ag. The areas around Veta Justina and Mina Vieja are now considered new high-priority targets for drilling. The company also commenced a Phase I drill program, which aims to delineate and expand known mineralization at the northern extension of the Aguilareña, Guadalupana, and Veta Central veins and to drill high-priority, previously undrilled targets at the Mark Twain, Veta West and Veta Justina areas. To date it has completed 647m of drilling across the first three holes. Pacifica Silver plans to apply for permits to drill new targets as part of the program.

ON MINING

Capstone Copper Corp., announced that it will present its Q3, 2025 results on October 30, 2025 (Cozamin mine, Zacatecas).
Goldgroup Mining Inc., notified that it has successfully installed a second crushing circuit at its Cerro Prieto mine in Sonora, doubling the crushing capacity to over 4,500 tonnes per day. This expansion is part of a broader optimization strategy aimed at increasing gold production to over 24K Oz annually. Additionally, the company plans to implement a re-leaching project on existing heap leach pads, which could yield an extra 8K Oz Au per year, with initial production expected in the first quarter of 2026. The mine has been in production since 2013 accumulating over 10M tonnes of mineralized material on the leach pads. Ongoing exploration efforts are also underway to extend the mine’s life and enhance resource availability.
Luca Mining Corp., confirmed that its Tahuehueto mine in Durango is operating normally following an environmental inspection by Mexico’s PROFEPA (Federal Attorney for Environmental Protection). The inspection assessed compliance with the Environmental Impact Authorization issued by SEMARNAT (Secretariat of Environment and Natural Resources). PROFEPA requested clarification on a 0.3-hectare inactive area previously used for tailings storage, leading to a temporary closure notice for that section pending updated technical documentation. Luca Mining plans to create a remediation plan that will not disrupt ongoing operations. The company emphasizes its commitment to environmental compliance and transparency, stating that the temporary notice does not affect current production. Luca Mining continues to operate normally at both the Tahuehueto and Campo Morado mines, focusing on production and sustainability initiatives.
First Majestic Silver Corp., reported Q3, 2025 production results from their Mexican operations. The table below shows mine by mine production details:

Endeavour Silver Corp., presented Q3, 2025 production results from Bolañitos and Guanacevi mines in Guanajuato and Durango respectively, and provided an update on its Terronera project in Jalisco.

ON RESOURCES AND DEVELOPMENT

Southern Silver Exploration Corp., initiated a drilling program at the Puro Corazon mine, which is adjacent to its 100% owned Cerro Las Minitas project in Durango, Mexico. Current development at the mine extends for approximately 200m laterally and to 250m below surface. The exploration program aims to integrate the nine-hectare Puro Corazon claim into the larger project and includes up to 12,000 meters of core drilling using three drill rigs. Drilling will test the further projections of the mined mineralization both laterally for an additional 200m and to depths of up to 450 metres below surface where the mineralization then transitions across the claim boundary and into the modelled Skarn Front deposit. Drilling will also target the projection of up to six hangingwall structures identified outboard of the main mineralized Skarn Front zone which was previously identified in both historic drilling within the Puro Corazon claim and in Southern Silver’s own drilling outside the claim boundary. The program will also compile existing geological data, conduct new sampling in historic underground workings, and perform a LiDAR survey to assess the extent of underground mining. Currently, the Puro Corazon mine is privately operated, producing approximately sixty tonnes of ore per day, generating silver-lead and zinc concentrates. The drilling will target lateral projections of mineralization and depths of up to 450 meters below the surface, focusing on six identified hangingwall structures. Results from this drilling will be incorporated into an updated Technical Report and Preliminary Economic Assessment (PEA) scheduled for the first quarter of 2026.
Heliostar Metals Ltd., released results from the current 15,000m drill program at its Ana Paula project in Guerrero. Drilling highlights include holes AP-25-329 with 3.29 g/t Au over 12.75m, and 5.17 g/t Au over 6.4m, and 8.82 g/t Au over 88.05m including 13.03 g/t Au over 35.5m; hole AP-25-326 with 6.29 g/t Au over 2.2m, and 2.37 g/t Au over 7m, and 18.8 g/t Au over 1m, and 2.86 g/t Au over 23m, including 4.19 g/t Au over 14.3m; and hole AP-25-327 with 32.1 g/t Au over 1.25m, and 2.75 g/t Au over 21.7m, including 8.36 g/t Au over 1.5m, and 2.73 g/t Au over 62.65m, including 4.61 g/t Au over 20.5m, and 5.63 g/t Au over 5m. The program has the primary goal of converting inferred ounces to higher confidence classifications, as well as supporting the ongoing Feasibility Study and testing the next exploration targets around the Ana Paula deposit.
Mithril Silver and Gold Limited reported exploration results from its Copalquin project in Durango. A district wide aerial magnetic survey is to commence later this month. Systematic mapping and sampling are ongoing at Target 3 to define priority targets, with maiden drilling planned in the coming months. At Target 5, an initial 5,000m drilling program is underway around the Apomal historic mine, with the first nine holes completed. The drilling aims to explore areas down-dip and along strike from old mine workings. Assays are pending. Mapping and sampling extended the silver-rich target to over 2km by 2km. Underground sampling highlights include 2.02 g/t Au and 1,938 g/t Ag over 3.21m including 2 g/t Au and 3,300 g/t Ag over 1.40 from the Tasonera Mine Level 2; and 10.25 g/t Au and 895 g/t Ag over 0.6m, and 3.31 g/t Au and 219 g/t Ag over 0.9m from Los Martires. Surface sampling highlights include 3.89 g/t Au and 157 g/t Ag over 0.5m from La Candelaria; 0.145 g/t Au and 284 g/t Ag over 0.5m from La Tasolera; 3.75 g/t Au and 555 g/t Ag over 0.65m and 24.5 g/t Au and 670 g/t Ag over 0.6m from Apomal; and 4.69 g/t Au and 520 g/t Ag over 0.5m from Los Martires. All these results indicate a significant presence of high-grade gold and silver mineralization in the Target 5, with notable underground and surface sample assays, suggesting strong potential for further exploration and resource development in the Copalquin district.
Torex Gold Resources Inc., released results from drilling program at ELG underground, primarily focused on drilling around the El Limón Sur and Sub-Sill trends within its Morelos Mine Complex in Guerrero. Drilling highlights for two second order structures running parallel to both the El Limón Sur and Sub-Sill trends, El Limón Sur Trend and Sub-Sill Trend are shown in the next three table below respectively:
