In the lithium mine tunnel excavation mining, Dazhong Mining for the first time to use the expensive TBM (rock with full section tunnel boring machine) equipment, although its price is as high as ten million yuan per meter diameter level, construction and operation and maintenance service costs are needed hundreds of millions of dollars, but the company firmly believe that this is a worthwhile investment.

When asked why the low price of lithium in the period choose to "rush time" to open the mine, Dazhong Mining Secretary Lin Puzheng said: "the most critical consideration of the use of TBM is to rush time. Our cost calculations show that even if the price of lithium carbonate products remain at 100,000 yuan / ton, we can maintain a high profit. Therefore, the sooner we go into production, the faster we can generate positive cash flow. Lithium mining is a cyclical industry, and the cycle trough is the best time for project construction. By accelerating mining, we expect to capitalize on the next up cycle."

In the interview, the company repeatedly emphasized that the Hunan lithium mining, metallurgy project is "grabbing time" to promote. With the adoption of TBM technology, the tunneling period has been shortened from four years to just one year, and the smelter site leveling work is nearing completion. In addition, the site selection for the ore dressing plant and tailing pond has been determined, and the prospecting work for the first mining area has been completed.

By utilizing TBM technology, Dazhong Mining has not only significantly improved its mining efficiency, but also shortened the project construction period. This time-saving strategy will help the company seize the opportunity to realize higher profits when lithium prices rise. Meanwhile, the company also focuses on cost control, reducing production costs and improving profit margins through refined management and autonomous operation of the entire industrial chain. These initiatives demonstrate Dazhong Mining's leading position and competitive advantage in the field of lithium mining.
