  • 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 the other hand, in the last year, Grupo Mexico became the largest company on the Mexican Stock Exchange by market capitalization exceeding USD $73.46B.
