SEGMENT AND RELATED INFORMATION: |
SEGMENT AND RELATED INFORMATION: | NOTE 19—SEGMENT AND RELATED INFORMATION: ​ Company management views Southern Copper as having three reportable segments and manages it on the basis of these segments. The reportable segments identified by the Company are: the Peruvian operations, the Mexican open-pit operations and the Mexican underground mining operations segment identified as the IMMSA unit. ​ The three reportable segments identified are groups of mines, each of which constitute an operating segment, with similar economic characteristics, type of products, processes and support facilities, similar regulatory environments, similar employee bargaining contracts and similar currency risks. In addition, each mine within the individual group earns revenues from similar type of customers for their products and services and each group incurs expenses independently, including commercial transactions between groups. ​ Intersegment sales are based on arm’s length prices at the time of sale. These may not be reflective of actual prices realized by the Company due to various factors, including additional processing, timing of sales to outside customers and transportation cost. Added to the segment data is information regarding the Company’s sales. The segments identified by the Company are: ​
1. | Peruvian operations, which include the Toquepala and Cuajone mine complexes and the smelting and refining plants, including a precious metals plant, industrial railroad and port facilities that service both mines. The Peruvian operations produce copper, with production of by-products of molybdenum, silver and other material.
​
2. | Mexican open-pit operations, which include La Caridad and Buenavista mine complexes and the smelting and refining plants, including a precious metals plant and a copper rod plant and support facilities that service both mines. The Mexican open-pit operations produce copper, with production of by-products of molybdenum, silver and other material.
​
3. | Mexican underground mining operations, which include five underground mines that produce zinc, copper, silver and gold, and a zinc refinery. This group is identified as the IMMSA unit.
​ The Peruvian operations include two open-pit copper mines whose mineral output is transported by rail to Ilo, Peru where it is processed at the Company’s Ilo smelter and refinery, without distinguishing between the products of the two mines. The resulting product, anodes and refined copper, are then shipped to customers throughout the world. These shipments are recorded as revenue of the Company’s Peruvian mines. ​ The Mexican open-pit segment includes two copper mines whose mineral output is processed in the same smelter and refinery without distinguishing between the products of the two mines. The resultant product, anodes and refined copper, are then shipped to customers throughout the world. These shipments are recorded as revenues of the Company’s Mexican open-pit mines. ​ The Company has determined that it is necessary to classify the Peruvian open-pit operations as an operating segment that is separate from the Mexican open-pit operations due to the very distinct regulatory and political environments in which they operate. The Company’s Chief Operating Decision Maker (“CODM”) must consider the operations in each country separately when analyzing results of the Company and making key decisions. The open-pit mines in Peru must comply with stricter environmental rules and must deal with a political climate that has a very distinct vision of the mining industry than that seen in Mexico. In addition, the collective bargaining agreement contracts are negotiated differently in each of the countries. These key differences result in the Company taking varying decisions with regard to open-pit operations in the two countries. ​ The IMMSA segment includes five mines whose minerals are processed in the same refinery. Sales of product from this segment are recorded as revenues of the Company’s IMMSA unit. While the Mexican underground mines are subject to a regulatory environment that is very similar to that applicable to Mexican open-pit mines, the nature of the products and processes of the two Mexican operations vary considerably. These differences cause the Company’s CODM to take a very different approach when analyzing results and making decisions regarding the two Mexican operations. ​ Financial information is regularly prepared for each of the three segments and the results of the Company’s operations are regularly reported to the CODM on the segment basis. The CODM of the Company focuses on operating income and on total assets as measures of performance to evaluate different segments and to make decisions to allocate resources to the reported segments. These are common measures in the mining industry. ​ Financial information relating to Company’s segments is as follows: ​

​ PROVISIONAL SALES PRICE: ​ At December 31, 2023, the Company has recorded provisionally priced sales of copper at average forward prices per pound, and molybdenum at the year-end market price per pound. These sales are subject to final pricing based on the average monthly copper prices on the London Metal Exchange (“LME”) or New York Commodities Exchange (“COMEX”) and Dealer Oxide molybdenum prices in the future month of settlement. ​ Following are the provisionally priced copper and molybdenum sales outstanding at December 31, 2023: ​
​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Sales volume |  | Priced at |  | ​
​ | ​ | (million lbs.) | ​ | (per pound) | ​ | Month of settlement
Copper | ​ | 169.2 | ​ | 3.89 | ​ | January through June 2024
Molybdenum | ​ | 13.2 | ​ | 20.00 | ​ | January through April 2024
​ Provisional sales price adjustments included in accounts receivable and net sales were as follows at December, 31 (in millions):
​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | At December 31,
​ |  | 2023 |  | 2022
Copper | ​ | $ | 17.8 | ​ | $ | 49.9
Molybdenum | ​ |  | 18.2 | ​ |  | 167.2
Total | ​ | $ | 36.0 | ​ | $ | 217.1
​ Management believes that the final pricing of these sales will not have a material effect on the Company’s financial position or results of operations. ​ LONG-TERM SALES CONTRACTS: ​ The following are the significant outstanding long-term contracts: ​ In 2022, a three-year copper cathodes sales agreement was signed with Mitsui, with shipments beginning in 2023. Mitsui and the Company will negotiate market terms and conditions for annual contracts no later than November 30 of the year prior to shipment. The contract considers the following annual volumes of copper cathodes; 48,000 tonnes for each of the years from 2023 through 2025. Failure to reach an agreement on market terms would cancel the annual contract but not the long-term agreement. Under the terms of the agreement all shipments would be to Asia and no exclusivity rights for Mitsui or commissions are included. This contract may be renewed for additional years, upon the agreement of both parties. ​ Under the terms of a sales contract with Molymet Group (Molibdenos y Metales, S.A., Complejo Industrial Molynor S.A. and Molymet Belgium N.V), SPCC Peru Branch is required to supply approximately 70% of the molybdenum concentrates production from 2023 through 2025. The sale price of the molybdenum concentrate is based on the average of the High and Low “Daily Dealer Oxide” as published in “Platt’s Metals Daily”. The roasting charge deduction is agreed based on international market terms. ​ Under the terms of a sales contract with Molymex, S.A. de C.V., Operadora de Minas de Nacozari, S.A. de C.V. and Operadora de Minas e Instalaciones Mineras, S.A. de C. V. are required to supply at least the 80% of their molybdenum concentrates production from 2020 through 2023. The sale price of the molybdenum concentrate is based on the average of the High and Low “Daily Dealer Oxide” as published in “Platt’s Metals Daily.” The roasting charge deduction is negotiated based on international market terms. ​ In 2019, a five-year sulfuric acid sales agreement was signed between SPCC Peru Branch and Marcobre, with shipments scheduled to begin in 2020. Marcobre and the Company will negotiate market terms and conditions for annual contracts no later than the last day of October of the year prior to shipment. The contract considers the annual volumes that could place Marcobre as the most important customer of sulfuric acid. Failure to reach an agreement on market terms would trigger a mechanism that force both parties to accept the Annual Benchmark for the region as the agreed price. This contract may be renewed for additional years, upon the agreement of both parties.
