Three Guizhou advanced mining technologies make national list

Three mineral exploration technologies developed by teams in Guizhou have been included in the first national list of advanced and applicable exploration technologies for the latest strategic campaign to achieve breakthroughs in mineral prospecting.

Released by the Ministry of Natural Resources, the list aims to promote technological innovation and accelerate the adoption of advanced, environmentally friendly exploration methods.

One of the selected technologies is a green drilling method known as "multi-hole drilling from a single platform", jointly developed by Guizhou geological survey team 112 and the Development Research Center of the China Geological Survey. By drilling multiple holes from a single site, the technology reduces the number of construction sites and cuts costs associated with roads, land use, equipment relocation and repeated drilling. It can reduce environmental disturbance to 10 to 50 percent of that caused by conventional exploration.

Structural geochemical surveying, another chosen technology, detects deep mineralization by selectively sampling materials from geological structures and alteration zones. It aids in finding hidden deposits, especially in regions with exposed bedrock and complex geological features.

The third technology is a geological model for predicting Carlin-type gold deposits in southwestern Guizhou. The model has guided gold exploration in the province and has already contributed to major exploration breakthroughs.

The inclusion of the three technologies highlights Guizhou's growing capacity to combine technological innovation with greener, more efficient mineral exploration.
