Together, the two months erased almost **$490 billion in market capitalisation**, reflecting mounting concerns about global economic growth, commodity demand and the direction of US monetary policy. Hotter-than-expected US inflation figures have strengthened expectations of further Federal Reserve interest rate increases, while selling pressure across technology stocks has prompted some investors to liquidate commodity-related holdings to cover losses elsewhere. **Gold was among the hardest-hit commodities, ending October at $3,884 an ounce, down 6.6% for the month.** The decline marked gold’s weakest October performance since 2008 and its first month-end close below $4,000 since September 2025. **The 16 gold mining companies represented in the global top 50 collectively lost $55 billion in market value**, a decline of 9.9%, leaving their combined valuation at approximately $500 billion. Major producers suffered substantial falls despite reporting encouraging operational and financial results. **Newmont declined 8.2%**, even after exceeding third-quarter profit expectations and announcing a **$4.8 billion investment plan to develop the Red Chris mine underground**. **Agnico Eagle** fell 9.9%, while **Barrick** declined 9.1%, leaving the three largest gold producers trading below their opening levels for 2026. **Kinross Gold and AngloGold Ashanti experienced even sharper losses, falling 17.3% and 15.8% respectively.** Silver also came under heavy pressure, recording its worst monthly performance of the year. **The metal plunged 18.2% to $49.39 an ounce**, leaving prices approximately 58% below their late-January peak. Rising inventories and concerns about weaker industrial demand have added to expectations that the silver market could shift from a supply deficit towards a surplus by 2027. **Copper mining companies recorded the largest combined dollar loss, with 11 major producers shedding $69 billion in market capitalisation**, equivalent to a 13.3% decline. The sell-off occurred despite copper prices remaining relatively resilient at approximately **$6.47 per pound**, suggesting that investor concerns extended beyond immediate commodity price movements. **BHP faced pressure after missing quarterly copper production expectations**, following a fatal accident and weather-related disruptions at its Escondida operation in Chile. Antofagasta declined **16.1% after issuing a weaker production outlook for 2027**, while Anglo American reported a 5% reduction in copper output following severe winter storms in Chile. The proposed Anglo-Teck merger also attracted regulatory scrutiny, with China’s antitrust authorities seeking supply commitments as part of the approval process. **Southern Copper and Freeport-McMoRan also weakened**, with Freeport falling below the $100 billion market capitalisation threshold despite beating quarterly profit estimates. The downturn extended to bulk commodities and battery metals. **Iron ore prices fell 6% to approximately $91 per tonne**, while **lithium carbonate declined 24% to 93,600 yuan per tonne**, reflecting concerns about industrial demand and supply conditions. **Vale shares dropped 15.4%** after the Brazilian mining group’s core profit fell 20% and production missed expectations. Australian iron ore producer **Fortescue declined 12.1%**, amid ongoing commercial tensions with China’s state-backed iron ore buyer. **Uranium was the only major commodity in the comparison to record a monthly price increase, gaining 3.5% to $92.55 per pound.** However, even uranium producers were not immune to the broader sell-off, with **Cameco shares falling 11.1%** despite the stronger underlying commodity price. The divergence highlights the extent to which investor positioning, financing conditions and broader market sentiment have influenced mining company valuations. **Trading activity across the sector also weakened significantly, with monthly share turnover falling to $243 billion**, its lowest level since November 2025. That represented barely half the volume recorded in January, suggesting reduced buying interest has contributed to the decline rather than a sustained surge in trading activity. However, lower turnover alone does not establish whether selling pressure or reduced demand has been the dominant driver. **For investors, the $712 billion decline highlights the mining industry’s exposure to inflation, interest rates, geopolitical uncertainty and changing expectations for global commodity demand.** The correction has affected companies across gold, copper, iron ore and lithium, including producers that have continued reporting strong earnings or operational progress. **Attention will now turn to Federal Reserve monetary policy, the outlook for industrial demand in China, developments in the Middle East and whether commodity prices can stabilise**, as the world’s largest mining companies seek to recover from two consecutive months of substantial market value losses. --- **Original URL:** https://www.share-talk.com/worlds-50-largest-mining-companies-lose-712bn-as-gold-copper-and-lithium-stocks-slump/ *Created by [WP Markdown Endpoint](https://wpmarkdownendpoint.com/)*
