COMMITMENTS AND CONTINGENCIES: | NOTE 9 — COMMITMENTS AND CONTINGENCIES: ​ Environmental matters: ​ The Company has instituted extensive environmental conservation programs at its mining facilities in Peru and Mexico. The Company’s environmental programs include, among others, water recovery systems to conserve water and minimize the impact on nearby streams, reforestation programs to stabilize the surface of the tailings dams and the implementation of scrubbing technology in the mines to reduce dust emissions. ​ Environmental capital investments in the six months ended June 30, 2019 and 2018 were as follows (in millions): ​
​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2019 |  | 2018
Peruvian operations | ​ | $ | 13.9 | ​ | $ | 18.0
Mexican operations | ​ |  | 18.4 | ​ |  | 26.5
​ | ​ | $ | 32.3 | ​ | $ | 44.5
​ Peruvian operations: The Company’s operations are subject to applicable Peruvian environmental laws and regulations. The Peruvian government, through the Ministry of Environment (“MINAM”) conducts annual audits of the Company’s Peruvian mining and metallurgical operations. Through these environmental audits, matters related to environmental obligation, compliance with legal requirements, atmospheric emissions, effluent monitoring and waste management are reviewed. Peruvian law requires that companies in the mining industry provide assurances for future mine closure and remediation. In accordance with the requirements of this law, the Company’s closure plans were approved by MINEM. See Note 6 “Asset retirement obligation,” for further discussion of this matter. ​ Air Quality Standards (“AQS”): In June 2017, MINAM enacted a supreme decree which defines new AQS for daily sulfur dioxide in the air. The Company believes that these new AQS will allow Peruvian industry to be more competitive with other countries. As of June 30, 2019, the Company maintains a lower daily average level of µg/m3 of SO2, than those required by the new AQS. ​ Soil Environmental Quality Standards (“SQS”): In 2013, the Peruvian government enacted SQS applicable to any existing facility or project that generates or could generate the risk of soil contamination in its area of operation or influence. In March 2014, MINAM issued a supreme decree, which established additional provisions for the gradual implementation of SQS. ​ In accordance with the regulatory requirements, the Company has been working on a characterization phase and a Soil Decontamination Plan (“SDP”) for environmentally impacted sites in each of its operating units (Toquepala, Cuajone, and Ilo) with the assistance of consulting companies. It is estimated that the Toquepala and Cuajone SDP will be presented to the authorities for review and approval at the end of the third quarter of 2019, and the Ilo SDP will be submitted during the last quarter of 2019. ​ While the Company believes that there is a reasonable possibility that a potential loss contingency may exist, it cannot currently reasonably estimate the amount of the contingency. The Company believes that a reasonable determination of the loss will be possible once the characterization study and the SDP are substantially completed and approved, which is expected for 2020. At that time the Company will be in a position to estimate the remediation cost. Furthermore, the Company does not believe that it can estimate a reasonable range of possible costs until the noted studies have substantially progressed and therefore is not able to disclose a range of costs that is meaningful. ​ Mexican operations: The Company’s operations are subject to applicable Mexican federal, state and municipal environmental laws, to Mexican official standards, and to regulations for the protection of the environment, including regulations relating to water supply, water quality, air quality, noise levels and hazardous and solid waste. ​ The principal legislation applicable to the Company’s Mexican operations is the Federal General Law of Ecological Balance and Environmental Protection (the “General Law”), which is enforced by the Federal Bureau of Environmental Protection (“PROFEPA”). PROFEPA monitors compliance with environmental legislation and enforces Mexican environmental laws, regulations and official standards. It may also initiate administrative proceedings against companies that violate environmental laws, which in the most extreme cases may result in the temporary or permanent shutdown of non-complying facilities, the revocation of operating licenses and/or other sanctions or fines. ​ In 2011, the General Law was amended, giving an individual or entity the ability to contest administrative acts, including environmental authorizations, permits or concessions granted, without the need to demonstrate the actual existence of harm to the environment as long as it can be argued that the harm may be caused. In addition, in 2011, amendments to the Civil Federal Procedures Code (“CFPC”) were enacted. These amendments establish three categories of collective actions by means of which 30 or more people claiming injury derived from environmental, consumer protection, financial services and economic competition issues will be considered to be sufficient in order to have a legitimate interest to seek through a civil procedure restitution or economic compensation or suspension of the activities from which the alleged injury derived. The amendments to the CFPC may result in more litigation, with plaintiffs seeking remedies, including suspension of the activities alleged to cause harm. ​ In 2013, the Environmental Liability Federal Law was enacted. The law establishes general guidelines for actions to be considered to likely cause environmental harm. If a possible determination regarding harm occurs, environmental clean-up and remedial actions sufficient to restore environment to a pre-existing condition should be taken. Under this law, if restoration is not possible, compensation measures should be provided. Criminal penalties and monetary fines can be imposed under this law. ​ On February 2019, the Mexican Supreme Court confirmed the constitutionality of an ecological tax to extractive activities developed in the state of Zacatecas, which taxes the environmental remediation actions, emissions of certain gases to the atmosphere, emissions of pollutant substances to the soil or water, and waste storage within the state territory. The Company is evaluating the potential impact of this new environmental regulation in its financial position. ​ The Company believes that all of its facilities in Peru and Mexico are in material compliance with applicable environmental, mining and other laws and regulations. The Company also believes that continued compliance with environmental laws of Mexico and Peru will not have a material adverse effect on the Company’s business, properties, result of operations, financial condition or prospects and will not result in material capital investments. ​ Litigation matters: ​ Peruvian operations ​ The Tia Maria Mining Project ​ There are four lawsuits filed against the Peruvian Branch of the Company related to the Tia Maria project. The lawsuits seek (i) to declare null and void the resolution which approved the Environmental Impact Assessment of the project; (ii) the cancellation of the project and the withdrawal of mining activities in the area and (iii) to declare null and void the mining concession application of the Tia Maria project. The lawsuits were filed by Messrs. Jorge Isaac del Carpio Lazo (filed May 22, 2015), Ernesto Mendoza Padilla (filed May 26, 2015), Juan Alberto Guillen Lopez (filed June 18, 2015) and Junta de Usuarios del Valle del Tambo (filed April 30, 2015). ​ The del Carpio Lazio case was rejected by the court of first instance on November 14, 2016. The plaintiff filed an appeal before the Superior Court on January 3, 2017. On January 9, 2018, the lawyers of both parties presented their respective positions before the Appellate Court. On March 8, 2018, the Appellate Court issued its final decision, which upholds the first instance ruling. On April 27, 2018, the plaintiff filed an extraordinary appeal before the Supreme Court. As of June 30, 2019, the case remains pending resolution. ​ The Mendoza Padilla case was initially rejected by the lower court on July 8, 2015. This ruling was confirmed by the Superior Court on June 14, 2016. On July 12, 2016, the case was appealed before the Constitutional Court. On November 20, 2018, the Constitutional Court reversed the previous decisions and remanded the case to the lower court for further action. As of June 30, 2019, the case remains pending resolution. ​ The Guillen Lopez case is currently before the lower court. As of June 30, 2019, the case remains pending resolution without further developments. ​ The Junta de Usuarios del Valle del Tambo case is currently before the lower court. On May 2016, the Company was included in the process, after the Ministry of Energy and Mines filed a civil complaint. On March 6, 2019, the Company was formally notified of the lawsuit and answered the complaint on March 20, 2019. As of June 30, 2019, the case remains pending resolution. ​ The Company asserts that these lawsuits are without merit and is vigorously defending against them. The potential contingency amount for these cases cannot be reasonably estimated by management at this time. ​ Special Regional Pasto Grande Project (“Pasto Grande Project”) ​ In 2012, the Pasto Grande Project, an entity of the Regional Government of Moquegua, filed a lawsuit against SCC’s Peruvian Branch alleging property rights over a certain area used by the Peruvian Branch and seeking the demolition of the tailings dam where SCC’s Peruvian Branch has deposited its tailings from the Toquepala and Cuajone operations since 1995. The Peruvian Branch has had title to use the area in question since 1960 and has constructed and operated the tailings dams with proper governmental authorization, since 1995. Upon a motion filed by the Peruvian Branch, the lower court has included MINEM as a defendant in this lawsuit. MINEM has answered the complaint and denied the validity of the claim. As of June 30, 2019, the case remains pending resolution without further developments. SCC’s Peruvian Branch asserts that the lawsuit is without merit and is vigorously defending against it. The amount of this contingency cannot be reasonably estimated by management at this time. ​ Mexican operations ​ The Accidental Spill at Buenavista Mine of 2014 ​ In relation to the 2014 accidental spill of copper sulfate solution that occurred at a leaching pond of the Buenavista mine, the following legal procedures are pending against the Company: ​ On August 19, 2014, PROFEPA, as part of the administrative proceeding initiated after the spill, announced the filing of a criminal complaint against Buenavista del Cobre S.A. de C.V. (“BVC”), a subsidiary of the Company, in order to determine those responsible for the environmental damages. During the second quarter of 2018, the criminal complaint was dismissed. This decision was appealed and remains pending resolution as of June 30, 2019. ​ Through the first half of 2015, six collective action lawsuits were filed in federal courts in Mexico City and Sonora against two subsidiaries of the Company seeking economic compensation, clean up and remedial activities in order to restore the environment to its pre-existing conditions. Two of the collective action lawsuits have been dismissed by the court. The plaintiffs in the four remaining lawsuits are: Acciones Colectivas de Sinaloa, A.C. which established two collective actions, Defensa Colectiva A.C.; and Ana Luisa Salazar Medina et al. which has been granted a collective action certification. The remaining plaintiffs have requested cautionary measures on the construction of facilities for the monitoring of public health services and the prohibition of the closure of the Río Sonora Trust. As of June 30, 2019, regarding the case of Ana Luisa Salazar Medina et al, the trial date has expired. Since the plaintiffs were notified of the expiration of their claims and did not appeal the resolution, this lawsuit has concluded, without responsibility for Buenavista del Cobre, S.A. de C.V. The other cases remain pending resolution as of June 30, 2019. ​ Similarly, during 2015, eight civil action lawsuits were filed against BVC in the state courts of Sonora seeking damages for alleged injuries and for moral damages as a consequence of the spill. The plaintiffs in the state court lawsuits are: Jose Vicente Arriola Nunez et al; Santana Ruiz Molina et al; Andres Nogales Romero et al; Teodoro Javier Robles et al; Gildardo Vasquez Carvajal et al; Rafael Noriega Souffle et al; Grupo Banamichi Unido de Sonora El Dorado, S.C. de R.L. de C.V; and Marcelino Mercado Cruz. In 2016, three additional civil action lawsuits, claiming similar damages, were filed by Juan Melquicedec Lebaron; Blanca Lidia Valenzuela Rivera et al and Ramona Franco Quijada et al. In 2017, BVC was served with thirty-three additional civil action lawsuits, claiming similar damages. The lawsuits were filed by Francisco Javier Molina Peralta et al; Anacleto Cohen Machini et al; Francisco Rafael Alvarez Ruiz et al; Jose Alberto Martinez Bracamonte et al; Gloria del Carmen Ramirez Duarte et al; Flor Margarita Sabori et al; Blanca Esthela Ruiz Toledo et al; Julio Alfonso Corral Domínguez et al; Maria Eduwiges Bracamonte Villa et al; Francisca Marquez Dominguez et al; Jose Juan Romo Bravo et al; Jose Alfredo Garcia Leyva et al; Gloria Irma Dominguez Perez et al; Maria del Refugio Romero et al; Miguel Rivas Medina et al; Yolanda Valenzuela Garrobo et al; Maria Elena Garcia Leyva et al; Manuel Alfonso Ortiz Valenzuela et al; Francisco Alberto Arvayo Romero et al; Maria del Carmen Villanueva Lopez et al; Manuel Martin Garcia Salazar; Miguel Garcia Arguelles et al; Dora Elena Rodriguez Ochoa et al; Honora Eduwiges Ortiz Rodriguez et al; Francisco Jose Martinez Lopez et al; Maria Eduwiges Lopez Bustamante; Rodolfo Barron Villa et al, Jose Carlos Martinez Fernandez et al, Maria de los Angeles Fabela et al; Rafaela Edith Haro et al; Luz Mercedes Cruz et al; Juan Pedro Montaño et al; and Juana Irma Alday Villa. During the first quarter of 2018, BVC was served with another civil action lawsuit, claiming similar damages. The lawsuit was filed by Alma Angelina Del Cid Rivera et al. During the last quarter of 2018, BVC was served with other three civil action lawsuits, claiming similar damages, such lawsuits were filed by Los Corrales de la Estancia, S.C. de R.L.; Jose Antonio Navarro; Jesus Maria Peña Molina, et al. As of June 30, 2019, these cases remain pending resolution. ​ During 2015, four constitutional lawsuits (juicios de amparo) were filed before Federal Courts against various authorities and against a subsidiary of the Company, arguing; (i) the alleged lack of a waste management program approved by SEMARNAT; (ii) the alleged lack of a remediation plan approved by SEMARNAT with regard to the August 2014 spill; (iii) the alleged lack of community approval regarding the environmental impact authorizations granted by SEMARNAT to one subsidiary of the Company; and (iv) the alleged inactivity of the authorities with regard of the spill in August 2014. The plaintiffs of these lawsuits are: Francisca Garcia Enriquez, et al which established two lawsuits, Francisco Ramon Miranda, et al and Jesus David Lopez Peralta et al. During the third quarter of 2016, four additional constitutional lawsuits, claiming similar damages were filed by Mario Alberto Salcido et al; Maria Elena Heredia Bustamante et al; Martin Eligio Ortiz Gamez et al; and Maria de los Angeles Enriquez Bacame et al. During the third quarter of 2017, BVC was served with another constitutional lawsuit filed by Francisca García Enriquez et al. In 2018, BVC was served with two additional constitutional lawsuits that were filed against SEMARNAT by Norberto Bustamante et al. Regarding the constitutional lawsuit filed by Maria Elena Heredia Bustamante et al; in which it was claimed the lack of community approval regarding the authorization granted by SEMARNAT to build the new BVC tailings dam, on September 5, 2018, the Supreme Court of Justice issued a resolution which established that such authorization was granted to BVC in compliance with the applicable legislation. However, SEMARNAT must carry out a public meeting to inform the community of the technical aspects required to build the dam, potential impacts and prevention measures, with no material effects to BVC’s operations. As of June 30, 2019, the remaining cases are still pending resolution. ​ It is not currently possible to determine the extent of the damages sought in these state and federal lawsuits but the Company considers that these lawsuits are without merit. Accordingly, the Company is vigorously defending against them. Nevertheless, the Company considers that none of the legal proceedings resulting from the spill, individually or in the aggregate, would have a material effect on its financial position or results of operations. ​ Corporate operations ​ Carla Lacey, on behalf of herself and all other similarly situated stockholders of Southern Copper Corporation, and derivatively on behalf of Southern Copper Corporation ​ In April 2019, a derivative lawsuit was filed against the Company, certain of its current and former Directors, and Grupo México in the Delaware Court of Chancery relating to certain construction contracts, contracts for the purchase and sale of minerals, and transportation contracts entered into between the Company’s subsidiaries and subsidiaries of Grupo México. The complaint alleges, among other things, that the construction contracts, the mineral contracts and the transportation contracts were unfair as a result of breaches of fiduciary duties and the Company’s charter. The complaint seeks, among other things, unspecified monetary damages. The complaint and the summons have not yet been served. The Company believes it has a meritorious defense to this action and that the action will not have an adverse effect on its financial position. ​ Labor matters: ​ Peruvian operations: 64% of the Company’s 4,834 Peruvian employees were unionized at June 30, 2019. Currently, there are six separate unions, one large union and five smaller unions. In June 2018, the Company signed a three-year collective bargaining agreement with one of the smaller unions. This agreement includes, among other things, annual salary increases of 5% for each year starting September 2018, and a signing bonus of S/45,000 (approximately $13,600) which was recorded as labor expense. In August 2018, the Company signed a three-year collective bargaining agreement with three additional unions. This agreement includes, among other things, annual salary increases of 5% for each year starting December 2018, and a signing bonus of S/45,000 (approximately $13,600) which was recorded as labor expense. In March 2019, the Company signed an agreement with one additional union. The agreement also included annual salary increases of 5% for each year starting September 2018, and a signing bonus of S/45,000 (approximately $13,600) which was recorded as labor expense in the first quarter of 2019. ​ As of June 30, 2019, the Company continues negotiations on collective bargaining agreements with one union. ​ Mexican operations: In recent years, the Mexican operations have experienced a positive improvement of their labor environment, as its workers opted to change their affiliation from the Sindicato Nacional de Trabajadores Mineros, Metalurgicos y Similares de la Republica Mexicana (the “National Mining Union”) to other less politicized unions. ​ The workers of the San Martin mine were on strike since July 2007. On February 28, 2018, the striking workers of the San Martín mine of IMMSA held an election to vote on the union that will hold the collective bargaining agreement at the San Martín mine. The Federacion Nacional de Sindicatos Independientes (the National Federation of Independent Unions), won the vote by a majority. Nevertheless, the vote was challenged by the National Mining Union. On June 26, 2018, the Federal Mediation and Arbitration Board issued a ruling recognizing the election results. Due to the agreement between workers and the Company to end the protracted strike, on August 22, 2018, the Federal Mediation and Arbitration Board authorized the restart of operations of the San Martín mine. Such authorization was challenged by the National Mining Union. On April 4, 2019, the Federal Mediation and Arbitration Board recognized again the election results from February 28, 2018; in which the National Federation of Independent Unions won by a majority. The Company is working on a rehabilitation plan to restore operations at the San Martin mine with a budget of $87 million. At June 30, 2019 the plan is in progress with a total expense of $50.1 million. The Company began production in the second quarter of 2019, and expects to fully restore production in the third quarter of 2019. ​ In the case of the Taxco mine, its workers have been on strike since July 2007. After several legal procedures, in August 2015, the Supreme Court decided to assert jurisdiction over the case and to rule on it directly. As of June 30, 2019, the case remains pending resolution without further developments. ​ It is expected that operations at the Taxco mine will remain suspended until the labor issues are resolved. In view of the lengthy strike, the Company has reviewed the carrying value of the Taxco mine to ascertain whether impairment exists. The Company concluded that there is a non-material impairment of the assets located at this mine. ​ Other legal matters: ​ The Company is involved in various other legal proceedings incidental to its operations, but the Company does not believe that decisions adverse to it in any such proceedings, individually or in the aggregate, would have a material effect on its financial position or results of operations. ​ Other commitments: ​ Peruvian Operations ​ Tia Maria: ​ On August 1, 2014, the Company received the final approval of Tia Maria´s Environmental Impact Assessment (“EIA”). On July 8, 2019, the Company received the construction permit for this 120,000 ton annual SX-EW copper greenfield project with a total capital budget of $1,400 million. This permit was obtained after completing an exhausting review process, complying with all established regulatory requirements and addressing all observations raised. ​ The Company´s commitment is to guarantee the population of Islay that the Tia Maria project will not adversely affect other local economic activities. The project will use only desalinated seawater for its operations and, for the transportation of its supplies and copper production, the Company will build an 32 kilometer industrial railway and an access road at a safe distance from the Tambo Valley. ​ The Company reiterates its commitment to delay the construction of the project until it has established, in coordination with the government, a common ground for dialogue with the neighboring communities to address any concerns and provide assurances to achieve more social support for the project. Meanwhile, the Company will continue to work for the welfare of the local population. ​ The Company´s social programs in education, healthcare and productive development will continue to improve the quality-of-life and the agricultural and livestock activities in the Tambo Valley, as well as the fishing and tourism in Islay. During the construction and operation phase, hiring local labor will be a priority. The Company has successfully launched in June the free technical training program “Forging the Future”, which will benefit 700 persons in this province in 2019-20. After training, the participants will be eligible to apply for one of the estimated 9,000 jobs (3,600 direct and 5,400 indirect) required during the Tia Maria construction phase. The Company strongly believes that the initiation of construction activities for Tia Maria will generate significant economic opportunities for the Islay province and the Arequipa region. ​ When in operation, the Company expects Tia Maria will generate a significant contribution through mining royalties and taxes from day-one and will directly employ 600 workers and indirectly provide jobs to another 4,200. ​ Tia Maria´s project budget is approximately $1.4 billion, of which $335.7 million has been invested through June 30, 2019. This project will use state-of-the-art SX-EW technology with the highest international environmental standards. SX-EW facilities are the most environmentally friendly in the industry as they do not require a smelting process and therefore, do not release any emissions into the atmosphere. ​ Michiquillay: ​ In June 2018, the Company signed a contract for the acquisition of the Michiquillay copper project in Cajamarca, Peru, at a purchase price of $400 million. Michiquillay is a world class mining project with estimated mineralized material of 1,150 million tons and a copper grade of 0.63%. It is expected to produce 225,000 tons of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years. ​ The Company paid $12.5 million at the signing of the contract. The balance of $387.5 million will be paid if the Company decides to develop the project and it is not a present obligation. ​ Toquepala Concentrator Expansion: ​ In April 2015, the construction permit for the Toquepala expansion project was approved by the MINEM. The project budget is $1,320 million, of which $1,291.6 million has been invested through June 30, 2019. When completed, this project is expected to increase Toquepala’s annual copper production to 258,000 tons in 2019, a 52% production increase, when compared to 2018. The construction of the project was completed and the project began production in the fourth quarter of 2018. Full production was reached in the second quarter of 2019. ​ Corporate Social Responsibility: ​ The Company has a corporate social responsibility policy to maintain and promote continuity of its mining operations and obtain the best results. The main objective of this policy is to integrate its operations with the local communities in the areas of influence of its operations by creating a permanent positive relationship with them, in order to develop the optimum social conditions and to promote sustainable development in the area. Accordingly, the Company has made the following commitments: ​ Tacna Region: In connection with the Toquepala concentrator expansion, the Company has committed to fund various social and infrastructure improvement projects in Toquepala’s neighboring communities. The total amount committed for these purposes is S/ 445.0 million (approximately $131.7 million). ​ Moquegua Region: In the Moquegua region, the Company is part of a “development roundtable” in which the local municipal authorities, community representatives and the Company discuss the social needs and the way the Company could contribute to sustainable development in the region. As part of this, the roundtable is discussing the creation of a Moquegua Region Development Fund for which the Company has offered a contribution of S/ 700 million (approximately $207.2 million). While final funding is not yet settled, the Company has committed to contribute S/ 108.5 million (approximately $32.1 million) in advance, which is being utilized to fund an educational project and S/ 48.4 million (approximately $14.3 million) for a residual water treatment plant in Ilo, a sea-wall embankment and a fresh water facility at El Algarrobal. ​ In addition, the Company has committed S/ 202.0 million (approximately $59.8 million) for the construction of six infrastructure projects in the Moquegua region under the “social investment for taxes” (obras por impuestos) program which allows the Company to use these amounts as an advance payment of taxes. ​ As the Toquepala expansion project has been completed, the Company considers that these commitments constitute present obligations of the Company and consequently has recorded a liability of $62.4 million in its condensed consolidated financial statements as of June 30, 2019. ​ Power purchase agreements: ​
● | Electroperu S.A.: In June 2014, the Company entered into a power purchase agreement for 120 megawatt (“MW”) with the state power company Electroperu S.A., under which Electroperu S.A. began supplying energy for the Peruvian operations for twenty years starting on April 17, 2017.
