When asked, "What are the technological content and barriers of the company's rolled copper foil? Who are the domestic and international competitors? Which companies are downstream clients?" North Copper responded on the investor interaction platform on June 25: The technological content and barriers of the company's rolled copper foil are reflected in: 1. The long process flow of rolled copper foil, involving disciplines such as smelting, rolling, metal heat treatment, and electrochemistry, requires continuous trial production to accumulate a process database. This represents a long-term experiential barrier that cannot be quickly reverse-engineered. 2. Capital and hardware thresholds, with extremely high equipment investment, high barriers for equipment installation, commissioning, and operation, and severe limitations on product width and ultra-thin gauge. 3. Barriers in rolling and forming processes, which are also the highest thresholds—covering product thickness, sheet flatness, internal structure, and mechanical properties, as well as the synergistic barriers of dozens of interconnected processing steps. The consistency control across the entire process is far more demanding than the single-step electrodeposition process for copper cathode foil. Regarding the statement, "The CCL construction portion of the company's 50,000 mt high-performance rolled copper foil and 2 million m² copper clad laminate (CCL) project has not yet commenced due to insufficient relevant technology and talent reserves, out of prudence. Next, the company will decide on the CCL investment and construction plan based on thorough market surveys and scientific validation," North Copper responded on the investor interaction platform on June 25: The CCL construction portion of the company's 50,000 mt high-performance rolled copper foil and 2 million m² CCL project has not yet commenced due to insufficient relevant technology and talent reserves, out of prudence. Next, the company will decide on the CCL investment and construction plan based on thorough market surveys and scientific validation. North Copper responded on the investor interaction platform on June 25: The company seizes market opportunities, closely monitors downstream market demand, focuses on R&D for mid-to-high-end copper strip products and structural adjustments for rolled copper foil products, and is committed to filling gaps in its process lines and reaching its capacity standard, striving to turn losses into profits as soon as possible.

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.
