SMM, April 22: According to SMM, zinc slag payables have remained at elevated levels. What are the reasons behind this? How will they trend going forward?

SMM identifies the following key reasons:

End-use consumption fell short of expectations. Galvanising enterprise operating rates in April were slightly better than in March, but overall rates missed expectations and were weaker YoY. Amid weakening demand, operating rates diverged between large and small producers. Overall zinc slag production was not high, and due to fewer orders, it was difficult for processing fees to rise. Galvanizing plants had limited room to offer concessions, keeping the payables relatively firm.

Zinc price movements provided support for zinc slag payables. In March, zinc prices continued to pull back, and considering cost concerns, some galvanising enterprises held back from selling, waiting for zinc prices to rebound before selling. The market experienced severe shortages, and the payables rose accordingly. Entering April, zinc prices rose notably, and galvanising enterprises' willingness to sell increased. However, some galvanising enterprises still had a mentality to hold prices firm when selling, and zinc slag payables stayed high.

In April, zinc oxide enterprises overall maintained good operating rates, and demand for raw materials rose. However, crude zinc enterprises only began to gradually resume production in March, leaving limited spot cargo in the market. Low-grade zinc oxide remained relatively tight. Zinc oxide enterprises' demand for zinc slag increased, and under conditions of undersupply, zinc slag payables stayed high.

Looking ahead, the zinc price center has shifted upward, but galvanizing plant operating rates remain lackluster. Zinc slag supply remains tight, while zinc oxide operating rates hold steady. Based on current galvanising enterprise operating rates and future expectations, there are limited opportunities for the payables to be adjusted downward.

Eldorado Gold’s McIlvenna Bay Project Slated for Commercial Production in Q3
Eldorado Gold announced that its McIlvenna Bay underground copper and zinc project in Saskatchewan, Canada, achieved a major milestone by producing its first copper concentrate in June 2026. The site team is now focused on ramping up operations toward commercial production, which is anticipated in Q3 2026 with a nameplate processing capacity of 4,900 tonnes per day. As of June 2026, the volcanogenic massive sulphide (VMS) deposit hosts mineral reserves of 29.7 million tonnes, grading a significant 2.17% zinc and 1.21% copper, along with 0.44g/t gold and 14.4g/t silver. Once fully operational, the 18-year mine is projected to produce an average of 54 million lbs of zinc, 41 million lbs of copper, 20,000 oz of gold, and 444,000 oz of silver annually. Eldorado acquired the project via its C$3.8 billion acquisition of Foran Mining in April 2026. The modern underground operation utilizes battery-electric vehicles (BEVs) and conventional flotation circuits to produce separate premium copper and zinc concentrates for toll smelters.

Silverco Mobilizes Contractors for Cusi Restart in Mexico, Heading for Year-End Lead-Zinc-Silver Production
Silverco Mining announced the mobilization of underground mining contractors at its wholly owned Cusi property in Chihuahua, Mexico, marking a critical milestone in the mine's restart plan. The company has appointed local experienced firms Mafrissa and Rencer to handle underground development and production mining across the Promontorio and San Miguel zones, respectively. Located in the Sierra Madre Occidental belt, the Cusi Complex is a historically productive underground mine renowned for its rich silver, lead, zinc, and gold deposits. Silverco expects the first ore from the Promontorio zone late in Q3 2026, while a new portal and ramp will be constructed at the San Miguel zone to ramp up production in H1 2027. CEO Mark Ayranto noted that with underground work and mill rehabilitation currently underway, the company remains strictly on schedule to produce its first concentrate in Q4 2026 and exit the year with two producing polymetallic mines in Mexico.

【SMM Flash】Russia Extends Industrial Sulphur Export Ban Through End-2026
Russia has officially extended its temporary sulphur export ban until December 31, 2026, according to Government Decree No. 785 signed on June 25, 2026. The ban was originally set to expire on June 30. The restriction continues to cover liquid, granular and lump sulphur. The Russian government stated that the move aims to prioritise domestic fertiliser production and safeguard national food security. Exemptions apply to exports destined for Eurasian Economic Union (EAEU) member states (including Belarus, Kazakhstan, etc.), as well as Abkhazia and South Ossetia. Sulphur shipments for humanitarian aid and international transit are also permitted under special licenses. The impact of the ban and broader market conditions has weighed on domestic output: Russia's industrial gaseous sulphur production fell 19% year-on-year to 1.75 million tonnes in January-May 2026.
