若按照氧化锂和碳酸锂之间的转换系数1:2.47换算，鸡脚山矿区通天庙矿段折合碳酸锂当量约为324.43万吨，大中矿业在公告中表示，其资源量超过公司预期。根据《矿产资源储量规模划分标准》(DZ/T0400-2022)的规定，已属于大型矿产资源储量规模。① Dazhong Mining released a reserve report for the Tongtianmiao mining section of its Jijia Mountain mining area, equivalent to approximately 3.2443 million tons of lithium carbonate equivalent; ② According to incomplete statistics from Financial Associated Press reporters based on public information, compared to lithium mica mines of similar low grade, the reserves of Dazhong Mining's Jijia Mountain mining area may only be second to those owned by contemporary amperex technology (300750.SZ).
Financial Associated Press, December 9 (Reporter Zeng Chuchu) Dazhong Mining (001203.SZ) has announced its first lithium mine ‘opening’.
Dazhong Mining announced this evening that its wholly-owned subsidiary, Chenzhou Chengtai Mining Investment Co., Ltd. (hereinafter referred to as 'Chenzhou Chengtai'), recently received a reply from the Ministry of Natural Resources regarding the review registration of the 'Lithium Mineral Exploration Report for the Tongtianmiao Mining Section of the Jijia Mountain Mining Area in Linwu County, Hunan Province'. The lithium mineral resources ore quantity approved this time for the Tongtianmiao Mining Section of the Jijia Mountain mining area is 489.872 million tons, with a lithium oxide mineral quantity of 1.3135 million tons and an average grade of 0.268%.
If converted using the conversion factor of lithium oxide to lithium carbonate of 1:2.47, the Tongtianmiao mining section of Jijia Mountain mining area is approximately equivalent to 3.2443 million tons of lithium carbonate, and Dazhong Mining stated in the announcement that the resource amount exceeds the company's expectations. According to the 'Standards for Classification of Mineral Resource Reserve Scales' (DZ/T0400-2022), it already falls under the category of large-scale mineral resources.
The secretary of the board of directors of Dazhong Mining, Lin Pu, indicated to the Financial Associated Press that after the approval of the reserve review registration, they have initiated the development and utilization plan for the first mining area in the Jijia Mountain mining area, as well as the geological environmental protection and land reclamation plan for the mine. They will then apply to the natural resources authority to handle the procedures for converting exploration rights to mining rights.
It is understood that Dazhong Mining began to lay out lithium mines in the Hunan area in 2022, acquiring 80% control of Chenzhou Chengtai in April 2023, and subsequently gained 100% equity through bankruptcy reorganization, thereby completely controlling the exploration rights of the Jijia Mountain lithium mine. The overall cost for the company to obtain exploration rights of the Jijia Mountain lithium mine was 0.209 billion yuan.
According to incomplete statistics from Financial Associated Press reporters based on public information, compared to lithium mica mines of similar low grade, the reserves of Dazhong Mining's Jijia Mountain mining area may only be second to those owned by contemporary amperex technology (300750.SZ). Publicly disclosed information reveals that the Jiangxi Yichun mine owned by contemporary amperex technology has an equivalent lithium carbonate amount of approximately 6.57 million tons, with an average lithium oxide grade of 0.27%; Zijin Mining Group (601899.SH) disclosed in last year’s annual report that the Dao County Xiangyuan lithium polymetallic mine’s reserves are equivalent to about 0.83 million tons of lithium carbonate, while Yongxing Special Materials Technology (002756.SZ) has equity reserves of approximately 2.79 million tons LCE from its Chashan ceramics stone mine. (Note: This comparison only considers lithium carbonate equivalent, and the grades and co-associated impurities vary between different mines, affecting extraction costs differently.)
Recently, Canmax Technologies (300390.SZ) subsidiaries won the mining rights to the ceramic clay (including lithium) mine in the Fengxin County Jinzi Peak – Yifeng County Zuojiali mining area for 2.51 billion yuan. According to bidding information, the ore quantity in the open-pit mining area of the Zuojiali mine (including lithium) is 0.206257 billion tons, with a corresponding lithium oxide quantity of 0.6388 million tons, and an average grade of 0.31%. Based on this estimate, the open-pit mining area ore quantity is approximately equivalent to 1.5778 million tons of lithium carbonate.
Dazhong Mining started with iron ore and announced in 2022 plans to invest over 10 billion yuan in the upstream of the lithium industry chain, and in 2023, it successfully acquired the "sky-high lithium mine" in Sichuan, gaining attention in the industry.
In Hunan, Dazhong Mining is advancing the exploration, mining, selection, and smelting of lithium mines. In terms of ore selection, Dazhong Mining has already established projects. The Shenjiawan processing plant is located in Chuyang Town, Linwu County, with a designed ore selection scale of 12 million tons/year, producing lithium muscovite concentrate with a grade of about 2.5%.
In terms of smelting, the first phase of the 0.02 million tons/year lithium carbonate project in Hunan has successfully acquired project land this February and has completed site leveling and preliminary design.
