Sweden Clears Key Hurdle for Boliden’s Laver Copper Project

China’s refined copper output is expected to decline year on year for a second consecutive month in August as persistent shortages of copper concentrate and other smelter feedstocks continue to weigh on operating rates.​ State-backed research house Antaike forecasts August refined copper production at around 1.05 million tonnes among surveyed producers representing 81.97% of China’s total smelting capacity, down 2.83% year on year. July output from the same group is estimated at a similar 1.05 million tonnes, representing a 3.18% annual decline and falling short of an earlier forecast of 1.07 million tonnes.​ The expected contraction reflects increasingly tight availability of raw materials. Copper concentrate supply has remained under pressure for an extended period, prompting smelters to lower capacity utilisation as competition for feedstock intensifies.​ The strain is also visible in treatment charges. Processing fees for imported copper concentrate have remained negative for 19 consecutive months, while charges fell to a record low of around minus $175.7/t on August 7, compared with minus $38.4/t during the same period a year earlier. The deepening negative charges highlight the severity of competition among smelters for available concentrate.​ At the same time, tighter domestic tax-invoice regulations have constrained the supply of VAT-compliant recycled copper, reducing another important source of smelter feedstock and adding further pressure to refined output.​ The expected second consecutive annual decline in refined production suggests that prolonged concentrate tightness is increasingly translating into constraints on finished copper supply. With China accounting for a dominant share of global smelting capacity, continued feedstock shortages could further tighten refined copper availability and increase the market’s sensitivity to additional disruptions in concentrate supply.

Copper is trading near record levels at around $14,500/t, while tightness in the London Metal Exchange market has intensified sharply. The August–September spread has widened to around $370/t, while the cash-to-three-month backwardation has reached approximately $434/t, highlighting increasingly strong demand for immediately available metal.​ The tightening market structure has coincided with a prolonged decline in exchange inventories. LME copper stocks have fallen for 42 consecutive days to 204,975 tonnes, with nearly half of the remaining material reportedly already earmarked for withdrawal. The combination of falling inventories and widening nearby premiums points to mounting pressure in the physical market.​ At the same time, copper flows are becoming increasingly fragmented geographically. Metal has been redirected toward the US amid expectations of possible 15–30% tariffs on refined copper, while demand for deliverable units in China has also strengthened as smelters face tighter feedstock availability following the DRC’s concentrate export restrictions.​ Supply-side constraints are adding to the pressure. Chilean copper production remains around 5.5 million tonnes per year, while Indonesia’s 342,000-tpy Gresik smelter is currently offline, reducing refined supply availability. These developments come as concentrate markets remain tight and smelter operating conditions stay under pressure.​ The increasingly pronounced backwardation suggests that the immediate issue for the copper market is not simply high prices, but access to physical metal. BMI currently expects 2026 copper prices to average around $13,500/t, while maintaining a view of strong upside risks. If LME inventories continue to decline, competition for warehouse metal could intensify further, increasing the risk of additional volatility in nearby contracts.

According to foreign media reports, Lloyds Metals & Energy has been authorized to undertake preparatory works and feasibility activities aimed at assessing the potential redevelopment of the Panguna copper-gold mine in Bougainville, Papua New Guinea, nearly four decades after the operation was shut down. The Autonomous Bougainville Government granted the authorization on August 7, allowing Lloyds to carry out an approved programme of preparatory and feasibility work required to assess and plan the future redevelopment of the mine. Lloyds is acting as the approved development partner of government-owned Bougainville Minerals, which holds the mining lease covering Panguna. The project represents a potentially significant source of long-term copper supply. Panguna's remaining reserves are estimated at approximately 5.3 million tonnes of copper and 19.3 million oz of gold, while Lloyds plans to revalidate the project's resource base as part of the redevelopment process. The mine has remained closed since 1989. The latest authorization follows the granting of a 25-year mining lease to Bougainville Minerals in June, providing a framework for further evaluation of the dormant asset. However, the current approval does not permit construction or copper production to begin. Any progression into those stages will require additional approvals, meaning a potential restart remains subject to further technical, regulatory and development work. The renewed progress at Panguna is notable given the scale of the historical deposit and growing efforts globally to develop additional copper supply. The immediate impact on mine supply remains limited, but successful feasibility work and resource revalidation could provide greater clarity on whether one of the world's largest dormant copper assets can eventually return to production.
