⚠ Estimate, not a measurement. Resource valuations are transparent estimates (spectral / orbital / remote-sensing assumptions), not measured or market values. A confirmed value requires in-situ prospecting. For research and illustration only — not investment advice.
资源估值为透明的估算(基于光谱/轨道/遥感的假设),非实测、非市场价。真正可信的价值需实地勘探。仅供研究与示意,不构成投资建议。
