Precious metals are rare, chemically stable, and high-value metallic elements that serve as both global safe-haven assets and indispensable strategic materials for new energy, semiconductors and high-end manufacturing. There are eight universally recognized precious metals in the world, divided into two categories:monetary precious metals (gold, silver) and six platinum-group metals (PGMs). Based on the latest USGS 2026 mineral data, this article briefly introduces their classification and global stockpiles. Henan Yusai Precision Machinery Co., Ltd., located in Zhengzhou, China, is a professional manufacturer specializing in R&D, production and sales of precious metal refining and solid waste recycling equipment. The company focuses on green extraction, purification and resource regeneration of precious metals from mineral materials and new energy solid waste, providing efficient, environmentally friendly and complete recycling and refining equipment solutions for global clients.
1. Core Classification of Precious Metals
1.1 Gold (Au) & Silver (Ag)
Gold features extreme chemical stability with almost no permanent loss. It is the core reserve asset of central banks worldwide, widely used for value preservation, jewelry and high-precision electronic manufacturing. Silver has the best electrical and thermal conductivity among all metals, dominated by industrial demand including photovoltaic silver paste, electronic components and energy storage materials. Different from gold, silver suffers irreversible consumption in industrial applications, leading to decreasing tradable inventories.
1.2 Platinum-Group Metals (PGMs)
The six PGMs include platinum (Pt), palladium (Pd), rhodium (Rh), iridium (Ir), ruthenium (Ru) and osmium (Os). They share excellent high-temperature resistance, corrosion resistance and catalytic performance. Rare and irreplaceable, they are mainly applied in automotive exhaust catalysis, hydrogen energy electrolysis, aerospace equipment and semiconductor coatings. Among them, rhodium is the scarcest with the most violent price fluctuations, while iridium and osmium are widely used in ultra-high temperature and precision military equipment.
2. Global Reserves and Stockpiles (2026 USGS Data)
Precious metal resources are counted in two key dimensions: economically mineable underground reserves and above-ground global inventories.
2.1 Gold
Global mineable reserves total 66,000 tons, mainly distributed in Australia and Russia, accounting for nearly 40% of the world’s total. The total above-ground gold mined in human history is about 210,000 tons, with around 35,000 tons held in central bank official reserves. Gold can be nearly 100% recycled, maintaining stable global circulation stockpiles.
2.2 Silver
Global silver mineable reserves reach 610,000 tons, concentrated in Peru, Russia and Australia. The total above-ground stock is about 277,000 tons. However, massive silver is permanently consumed in thin industrial coatings and microcircuits, resulting in continuously shrinking available tradable supplies.
2.3 Platinum-Group Metals
The total global PGM reserves are 63,000 tons, with an extremely concentrated supply: South Africa occupies 83% and Russia 15% of global reserves. Affected by resource endowments, the annual output of rare PGMs such as rhodium, iridium and osmium is extremely low, leading to high global supply risks.
3. Market Value Core Logic
Gold is the global financial anchor with stable value preservation attributes. Silver is a dual-value metal integrating finance and new energy industry, with growing demand driven by photovoltaic and energy storage sectors. PGMs are core materials for high-end manufacturing, whose prices and supplies are highly sensitive to geopolitics and regional mining conditions. With the upgrading of global new energy and semiconductor industries, precious metals have evolved from traditional jewelry and safe-haven assets into critical strategic mineral resources supporting technological development. Against the backdrop of tight global precious metal reserves and rising resource recycling demand,Henan Yusai Precision Machinery Co., Ltd. focuses on technological innovation in precious metal extraction and solid waste resource utilization.
