Report Summary 1. Report Industry Investment Rating - Not provided in the given content 2. Report's Core View - The resumption of production at the Wabang Manxiang tin mine in Myanmar still takes time and the fee standard has increased, there are still disruptions in refined tin production in Malaysia, and the inventories of refined tin at home and abroad are decreasing. These factors may cause the price of Shanghai tin to be cautiously bullish. It is recommended that investors hold their previous long positions cautiously, paying attention to the support levels and pressure levels of Shanghai tin and London tin [2]. 3. Summary by Relevant Catalogs 3.1 Market Data - Shanghai Tin Futures: On April 28, 2025, the closing price of the active contract was 260,570, down 2,270 from the previous day; trading volume was 48,003 lots, down 24,008 lots; open interest was 12,035 lots, down 5,566 lots; inventory was 8,722 tons, down 192 tons [1]. - Shanghai Tin Basis and Spreads: The SMM 1 tin semi - average price was 260,200, down 2,800; the Shanghai tin basis was - 370, down 530; the spread between the near - month and the first - consecutive contract was - 20, up 50; the spread between the first - consecutive and the second - consecutive contract was 80, down 320 [1]. - London Tin: The closing price of the LME 3 - month tin futures (electronic trading) on April 25 was 31,975; the LME tin 0 - 3 - month contract spread was - 166.99; the LME tin 3 - 15 - month contract spread was - 135; the LME global tin inventory was 2,845 tons; the LME registered inventory was 2,415 tons; the cancelled warrants were 430 tons; the Shanghai - London tin price ratio was 8.15, down 0.07 [1]. 3.2 Project Information - Oropesa Project: It will make the company the first European vertically - integrated tin producer from mine to metal. The feasibility study outlines a 1.4 - million - ton - per - year open - pit mine, expected to produce an average of 3,405 tons of tin per year over a 12 - year mine life and be processed at a local smelter in Spain. The first ore reserve report shows a reserve of 15.9 million tons, with a tin grade of 0.36% and a metal content of 57,900 tons [1]. 3.3 Industry News - Wabang Mining: On April 23, 2025, a symposium on the resumption of production of the Manxiang tin mine was held, clarifying the process of obtaining mining, concentrator, and exploration licenses. The new fee standards are significantly higher than those in 2023, which will increase the cost pressure on low - altitude mines and small - and medium - sized concentrators. The full resumption of normal mining is expected to take about two months, and the resumption of production in Wabang and the restart of the Bisie tin mine in Congo (Kinshasa) may relieve supply pressure to some extent [1]. 3.4 Supply and Demand Analysis - Supply: The resumption of production in Wabang and Congo (Kinshasa) may affect domestic tin ore production and imports, and domestic tin concentrate processing fees are expected to decline, indicating a tight supply of domestic tin ore. The supply of scrap tin is expected to increase, and the production of recycled tin in China in May may increase. The operating rates of refined tin production capacity in Jiangxi and Yunnan have decreased, and the production and inventory of refined tin in China in May may decrease. The export volume of Malaysia's MSC smelting company may increase, and the import volume of refined tin in China in June may increase [1]. - Demand: The daily processing fee of photovoltaic solder strips has decreased, and the operating rate of tin solder production capacity in China in May may decline. The import volume of solder strips in China in May may decrease, and the export volume may increase. The production volume of tin - plated sheets in China in June may increase, while the import and export volumes may decrease. The operating rate of lead - acid battery production capacity in China has increased [1].
