Based on decades of work and reference to the history of foreign mineral exploration, mineral exploration can be roughly summarized as follows 4:00. 4.1 The Natural Attributes of High-risk Mineral Resources Determine many uncertainties in mineral geological exploration. Even if the ore bodies are exposed to the surface, it is hard for the clever miners to estimate the deep extension of the ore body. A large number of mineral deposits are hidden, outcrop mine less, and mainly based on geological,
