Record market cap, but stalled momentum as conference season approaches

Mining companies are heading into this year's investor conference season with an all-time-high aggregate market capitalization, even as executives grapple with an energy cost shock that has undercut margins and forced dealmakers to rework their playbooks. Kitco Mining will be recording CEO interviews at the 2026 Precious Metals Summit (PMS) Sept. 22-25 and at Mining Forum Americas (MFA) Sept. 27-30. MFA is expected to see its biggest attendance ever, with projections for more than 1,300 participants, split between investors and issuers, with a record 205 Denver Gold Group (DGG) member companies attending and another 10 non-member mining company representatives. “They have an aggregate market capitalization of US$1.2T,” said Tim Wood, executive director of the DGG, almost double the US$675B in 2025. Australian companies are now a firm fixture, with 50 ASX-listed companies comprising about 25% of the participating companies. 2026 has been an eventful year for the metals sector. Precious metals entered the year hot, with gold topping at US$5,600/oz and silver at US$120/oz in March before the outbreak of the conflict with Iran dinged confidence. The impact of higher long-term interest rates and a stronger U.S. dollar sent the gold price below US$4,000/oz, a level it has held, trading sideways since then and only recently starting a climb above US$4,500/oz again. “The rally has lost steam since the spring. Even after gold and silver prices had already pulled back from earlier highs, market mood remained upbeat until the outbreak of the Iran war disrupted sentiment across the board. Energy input costs became a critical swing factor, eroding margins that companies had spent months rebuilding,” said Wood. Higher energy prices and costs for other inputs impacted by the Iran conflict and the closure of the Strait of Hormuz shipping lanes saw all-in sustaining costs (AISC) jump in the quarter to June 30. AISC jumped 9.5% to US$1,876/oz from 1Q26 and 22.5% from 2Q25 for the majors, but just 2% from 1Q26 and 13% from 2Q25 to US$1,934/oz for the mid-tier producers. This new energy shock has caused countries and companies to rethink energy security and source diversification. China’s recent five-year plan for oil and gas includes a target to expand domestic oil and gas supply that includes adding 20,000km of new long-distance pipelines by 2030 and raising natural gas reserves to the equivalent of more than 13% of national consumption. Australia and Australian miners have also been planning to increase alternatives. “This episode has reframed the industry's energy conversation away from net-zero targets and toward diversification. Companies can no longer concentrate reliance on a single category of power generation, and nuclear needs to be part of the broader energy mix,” said Wood. While sector profits remain high, the Iran conflict's energy impact has knocked the wind out of its sails and introduced doubt into long-term capital decisions. Future energy price uncertainty sees companies redrafting cost and profitability models for development projects and acquisition targets. “This volatility follows two years of an unbridled run that had taken gold from US$2,000/oz to US$5,500/oz before stalling. Many companies' internal deal books, assembled during the earlier bull run, were upended by the combination of higher energy costs and softer metals prices, forcing management teams to rebuild return assumptions from scratch,” said Wood. Returns Costs may be increasing and prices may have come down, but gold producers still enjoyed margins of about US$2,400-US$2,500/oz in the June quarter. This cash bonanza saw senior gold producers grow their cash on the balance sheet to US$29B and US$10.5B for the mid-tiers; at the same time, long-term debt was reduced to US$16.9B for the majors and US$5B for the mid-tiers. With balance sheets in perhaps the best condition they have ever been, returns to shareholders remain a str...
