China’s Rhenium Reserves More Than Triple; Gold, Nickel, Zirconium Rise Sharply

The headline number is rhenium, but the mechanism is the story: a reclassification of co-associated and low-grade material into reserves, not fresh discovery. That distinction matters for anyone tracking critical-minerals supply, because book reserves can shift without any new tonnes reaching a market — rhenium's scarcity narrative rests on recoverability, and hard-to-process material stays hard to process. The gold and nickel uplifts are large in deposit-equivalents but similarly reflect reassessment. Whether these upgraded reserves translate into actual output, and how quickly processing capacity follows, is the open question worth watching.
