Abstract: Chinese mining enterprises “going out” have become an inevitable choice for their own growth and development.In recent years, many Chinese mining enterprises have developed outwards and actively participated in the global mining mergers and acquisitions (M & A) market.However, the opportunities and risks of mining investment coexist, and the road to M & A has not been smooth sailing.Therefore, it is particularly necessary for mining enterprises to analyze typical cases and learn from successful experiences.Zijin Mining’s bid for Guyana Goldfields Inc.is a wonderful case of merger and acquisition in the mining industry in 2020.Through this merger and acquisition, Zijin Mining won an overseas large-scale mine with an annual output of more than 4 tons of gold and 185 tons of gold resources at a low cost, gained a foothold in Guyana and opened the door of Guyana mining market.This paper reviews this bidding, and thinks that Zijin Mining’s successful experience lies in firmly implementing the company’s development strategy, accurately finding and evaluating high-quality projects according to its own management and technological advantages, locking projects in the bidding process by using reasonable operation methods and quick decision-making mechanism, and realizing the efficient integration and production after merger and acquisition.These experiences have important reference significance for large mining enterprises in China that are committed to cross-border mergers and acquisitions.
