1. Price comparison conditions
This quotation project: In accordance with the Mineral Resources Law of the People’s Republic of China (Presidential Order No. 36 of the People’s Republic of China), after Chongqing Sote Salt Chemical Co., Ltd. has obtained the real estate certificate for its mining rights in the Gaofengchang Rock Salt Mining Area, it must re-apply for a mining permit. Currently, it is necessary to commission a technical agency to prepare a mineral resource exploitation plan, which will serve as one of the required documents for the Natural Resources Administration to issue the mining permit. The client responsible for preparing this exploitation plan is Chongqing Sote Salt Chemical Co., Ltd., and the funding will come from the company’s own resources. The project now meets the conditions for price comparison, and we are hereby inviting quotations for the preparation of the said exploitation plan.
2. Project Overview and Price Comparison Scope
2.1 Project Location
In the Gaofengchang rock salt mine area of Chongqing Sote Salt Chemical Co., Ltd.
2.2 Project Overview and Technical Solution
Based on the existing distribution of brine wells and the reserves of rock salt in the Gaofengchang Rock Salt Mine, and in accordance with current regulations, standards, and technical requirements (guidelines), prepare an mining plan for the Gaofengchang Rock Salt Mine of Chongqing Suote Salt Chemical Co., Ltd., providing the foundational geological basis for the project owner to obtain a mining permit.
2.3 Project Scale
According to the “Verification Report on Mineral Resource Reserves of the Gaofengchang Rock Salt Mine of Chongqing Sote Salt & Chemical Co., Ltd.,” submitted in July 2024 by the No. 107 Geological Team of the Chongqing Municipal Bureau of Geology and Mineral Exploration and Development, as of June 30, 2024, the total proven + controlled + inferred mineral resource reserves within the Gaofengchang rock salt mining area of Chongqing Sote Salt & Chemical Co., Ltd. for the three salt-bearing strata—T2b1-1, T2b1-3, and T2b3-2—amounted to 199,295 thousand tons (equivalent to 1,564,470 thousand tons of NaCl). Specifically, the proven reserves totaled 10,143 thousand tons (equivalent to 76,990 thousand tons of NaCl), the controlled reserves stood at 48,415 thousand tons (equivalent to 374,250 thousand tons of NaCl), and the inferred reserves reached 140,737 thousand tons (equivalent to 1,113,230 thousand tons of NaCl). With a comprehensive recovery rate of 25%, a reliability coefficient of 1.0 is applied to both the controlled and proven reserves, while a coefficient of 0.65 is used for the inferred reserves. Given a production scale of 1 million tons per year (in terms of brine equivalent salt), the estimated mineable ore reserves are 37,509 thousand tons, yielding a mine service life of approximately 28.9 years.
