Mountain quest reveals hidden riches

Surprisingly, they have made some discoveries. For example, they have found hard gray-green rocks that exhibit a metallic luster under a magnifying glass — which is highly consistent with the characteristics of lead-zinc ores in the known Lanping deposit — suggesting a likelihood of mineral resources in the region.

Additionally, there are some findings for which they haven't yet found a definite explanation, such as rocks that emit an odor similar to asphalt when chipped and rocks with sapphire-like speckles.

"Our work in mineral exploration is like opening a blind box: we never know what we will find next, but every discovery brings us closer to unlocking the secrets of the Earth's mineral wealth. This is both the responsibility and the charm of the job I undertake," Li said.
