Core Insights - The recent exploration in the Sartuohai area of Xinjiang has led to the discovery of the Sartuohai 27 ore cluster, identifying 20 ore bodies with an average grade of 30.73%, marking the largest mineral discovery in the region in nearly 40 years, which supports the chromium ore exploration goals for the 14th Five-Year Plan [1][2] Group 1 - The exploration utilized innovative chromium ore exploration techniques, establishing a combination of "lithofacies zoning + alteration zoning + structure" as exploration markers [1] - A new technology for extracting weak anomaly signals through multiple geophysical methods at various scales was developed, leading to the verification of 13 drill holes, with 10 encountering thick layered chromium industrial ore bodies, significantly improving ore body positioning accuracy [1] - The study redefined the mineralized lithofacies in the Sartuohai region, discovering 11 chromium ore bodies in carbonatized ultrabasic rocks, which accounted for 70% of the total ore discovered, thus expanding the exploration potential in the area [1] Group 2 - The significant findings from the Sartuohai exploration have boosted confidence in chromium ore exploration and established a successful model of central-local coordination and concentrated efforts to tackle challenges, providing valuable insights for similar chromium ore exploration initiatives [2]
