According to foreign media reports, the Ecuadorian government announced on May 29 that it would renegotiate the mining contract for the Cascabel copper mine, stating that its terms violated national laws and created an imbalance between the government and the company. The mining concession, located in Imbabura Province, was originally held by Australia's SolGold, and Jiangxi Copper Corporation completed its acquisition for approximately $1.16 billion in March this year. Ecuador's Minister of Energy and Environment stated that if renegotiation was refused, the government would seek another operator. The concession holder ENSA countered that the contract was signed in compliance with regulations and expressed willingness to communicate with the government. Ecuador has issued new minimum parameters for mining contracts, allowing the review or modification of existing contracts, though the previously signed Cangrejos gold mine contract is not subject to renegotiation.

In 2026, global competition for critical minerals has entered a white-hot phase. Geopolitical maneuvering continues to deepen, and global industry and supply chains are undergoing accelerated restructuring. A new round of technological revolution, driven by AI semiconductors, new energy, high-end manufacturing, and aerospace, is propelling the minor metal industry into a historic period of both developmental opportunity and profound transformation. Globally, the EU’s Critical Raw Materials Act and the US Inflation Reduction Act (IRA) are being implemented, while the Minerals Security Partnership continues to expand. The localization and regionalization of critical mineral supply chains are intensifying. The scramble for resources, technical barriers, and the reshaping of trade rules surrounding strategic minor metals such as antimony, indium, gallium, germanium, bismuth, selenium, tellurium, and rhenium have become central focuses of global high-end manufacturing competition. As the world’s core supplier of minor metals, China holds a dominant global position in the smelting and supply of multiple minor metal varieties. Against this backdrop, the 2026 SMM (14th) Minor Metals Industry Conference will convene upstream and downstream enterprises across the entire industry chain for antimony, indium, gallium, germanium, bismuth, selenium, tellurium, and rhenium, along with research institutes, government agencies, financial and investment institutions, and trade service providers, to create a high-standard, full-chain, and in-depth platform for exchange and cooperation. The conference will provide in-depth analysis of global policy shifts, assess the supply-demand pattern and price trends, identify growth opportunities in end-use applications, and facilitate connections between government-enterprise resources and cross-border cooperation. It aims to help enterprises accurately grasp industry trends, overcome development bottlenecks, optimize supply chain layouts, and seize market opportunities to jointly promote the high-quality, sustainable development of China’s minor metal industry. Shandong Humon Smelting Co., Ltd. will make a significant appearance at this conference. We will keep pace with the times, set our sights on goals, forge ahead with determination, and press forward with courage! Click the now to sign up for the conference. We look forward to meeting you there. Shandong Humon Smelting Co., Ltd. (referred to as "Shandong Humon Smelting") was founded in 1988, dedicated to building a world-class precious metal smelting enterprise where employees are happy, clients are satisfied, and the environment is harmonious. It was listed on the Shenzhen Stock Exchange on May 20, 2008 (stock code: 002237), and in 2019, Jiangxi Copper Corporation became the company’s controlling shareholder. Riding on the momentum of reform and opening-up and leveraging its expertise in technological innovation, the company has firmly pursued market-oriented and international operations. Through over 30 years of enduring entrepreneurship, it has remained China’s largest gold smelting enterprise for 12 years. In 2025, it generated operating revenue of 112 billion yuan and produced 100 mt of gold. As a pioneer and leader in "pyrometallurgy," the company uses fire-based processes as its foundation and integrates the entire industry chain, establishing a comprehensive "cyanide-free pyrometallurgical environmentally friendly technology system." This has been recognized with two second-class National Science and Technology Progress Awards and 11 first-class provincial and ministerial-level Science and Technology Progress Awards. Focusing on the transformation and upgrading of gold ore smelting, the company has proposed a strategic vision to "unlock limitless value from limited resources and lead the green development of gold ore smelting." While developing gold and silver products, it concurrently achieves the comprehensive extraction of metals including copper, lead, zinc, antimony, selenium, tellurium, and platinum, forming a diversified development pattern encompassing gold mines, metal smelting, international trade, and high-purity materials. Looking ahead, the company will follow the guidelines, principles, and policies of the Party and the nation, integrate global mineral resources, create wealth for the era in China, and embark on a new journey of high-quality, leapfrog development, striving unremittingly to become a world-class precious metal smelting enterprise.
