1. Report Industry Investment Rating - Zinc: Bearish; Lead: Sideways [6] 2. Core Views of the Report - In Q1 2025, overseas zinc concentrate production increased year - on - year, while lead concentrate production decreased. The zinc smelting industry is expected to see increased supply in Q2, but the lead market has uncertainties due to production disruptions. In June, lead and zinc prices will be demand - driven. For zinc, short - term oversupply is expected, and for lead, the market is in a bearish pattern [2][3][4]. 3. Summary by Relevant Catalogs 3.1 Event Overview - Recently, overseas leading mining companies announced their Q1 2025 production. Some adjusted their 2025 production guidance. The report statistics cover 30 overseas leading mining companies, with the sample proportion of zinc concentrate rising from 60% to about 65% and that of lead concentrate from 40% to 49% [11]. 3.2 Zinc Concentrate and Lead Concentrate Production - **Zinc Concentrate**: In Q1 2025, overseas sample zinc concentrate production was 1.312 million metric tons, a 6.4% year - on - year increase and a 4% quarter - on - quarter decrease. The increase was due to large - scale project restarts, new project ramp - ups, higher grades and recoveries, a low base in the previous year, and fewer disruptions. The decrease was due to seasonal factors and end - of - year production rushes [12]. - **Lead Concentrate**: In Q1 2025, overseas sample lead concentrate production was 300,000 metric tons, a 4.4% year - on - year decrease and a 9.2% quarter - on - quarter decrease. The decline was mainly due to lower ore grades, external disruptions, and reduced operational efficiency [13]. 3.3 Production Changes and Factors of Individual Mining Companies - **Zinc Concentrate**: The top five companies with year - on - year production increases were Ivanhoe, Vedanta, Boliden, Group Mexico, and Sibanye - Stillwater. The top five with decreases were Teck, NEXA, Peñoles, MMG, and South32. The increase was mainly due to large - scale project restarts, new project ramp - ups, higher grades and recoveries, etc. The decrease was due to lower grades, external disruptions, and reduced operational efficiency [27][29]. - **Lead Concentrate**: Companies including Volcan, Glencore, Vedanta, Pan American Silver, and Silvercrop contributed to the year - on - year increase, while South32, Newmont, Aurelia Metals, NEXA, and MMG contributed to the decrease [27]. 3.4 Zinc Mine Costs - The 90% cash cost quantile of zinc mines in 2025 is $1,993/ton, a 9.3% year - on - year decrease. Although the LME zinc price has declined, the mining end still has sufficient profits. Different companies' cost changes vary due to factors such as mining costs, processing fees, and by - product contributions [47]. 3.5 Production Guidance - Among 13 leading mining companies, only South32 slightly lowered its annual production guidance in Q1. The total 2025 production is expected to be between 2.839 and 3.1 million metric tons, a 4.7% year - on - year increase. Some projects are expected to increase production, while others may continue to face production declines [48][50]. 3.6 TC Views and Investment Recommendations - **Zinc Concentrate TC**: There may be a slight upward space in Q2 2025, but in the second half of the year, upward movement may be restricted or even decline slightly due to factors such as domestic seasonal production increases, bearish zinc price expectations, and potential overseas production shortfalls. - **Lead Concentrate TC**: Overseas production is expected to increase slightly in Q2 2025, but domestic imports may be limited, and there is a downward expectation for the medium - term TC. - **Investment Strategy**: For zinc, in June, it is recommended to short on rallies on a medium - term basis and maintain a long - short arbitrage strategy between domestic and overseas markets. For lead, it is recommended to look for medium - term long opportunities after demand reaches a low point [52][53].
