See Item 1 “Business—Cautionary Statement.” ​ EXECUTIVE OVERVIEW ​ Business: Our business is primarily the production and sale of copper. In the process of producing copper, a number of valuable metallurgical by-products are recovered, which we also produce and sell. Market forces outside of our control largely determine the sale prices for our products.
In the process of producing copper, a number of valuable metallurgical by-products are recovered, which we also produce and sell. Market forces outside of our control largely determine the sale prices for our products. Our management, therefore, focuses on value creation through copper production, cost control, production enhancement and maintaining a prudent capital structure to remain profitable.
This decrease was attributable to a decrease in sales volumes of copper (-2.0%) and molybdenum (-3.1%) and to a decrease in the prices for copper (-5.4% – LME) and silver (-13.6%).
This decrease was driven by lower copper (-3.8% - LME) and zinc (-24.1%) prices, along with a reduction in the sales volumes of silver (-4.3%) and zinc (-1.4%). This impact was partially offset by increased sales volumes for copper (+2.2%) and molybdenum (+2.3%) and by better prices for molybdenum (+27.5%) and silver (+7.6%).
The effect of this change was an increase in the asset retirement obligation of $269.3 million, which was recorded in December 2020. 104 Table of Contents In 2022, after a detailed review of their closing activities, the Company recorded an adjustment in its asset retirement obligation provision of $43.3 million for Mexico and a $59.5 million for Peru. ​ Asset retirement obligations are further discussed in Note 10 “Asset Retirement Obligation” to the consolidated financial statements included herein. ​ Revenue Recognition : For certain of our sales of copper and molybdenum products, customer contracts allow for pricing based on a month subsequent to shipping, in most cases within the following three months and in a few cases, in a period that can exceed three months.
Any such increases in future costs could materially impact the amounts charged to operations for reclamation and remediation. ​ Asset retirement obligations are further discussed in Note 10 “Asset Retirement Obligation” to the consolidated financial statements included herein. ​ Revenue Recognition : For certain of our sales of copper and molybdenum products, customer contracts allow for pricing based on a month subsequent to shipping, in most cases within the following three months and in a few cases, in a period that can exceed three months.
The project includes an open-pit mine with a combined concentrator and SX-EW operations. Annual production is expected to total 190,000 tonnes of copper and 105,000 ounces of gold.
The project includes an open-pit mine with a combined concentrator and SX-EW operations.
In both questionnaires we achieved “B” result (third best score on a scale of eight levels), which is one level above the mining sector average score and the North America region overall score. ​ Additionally, given the importance of water for our operations and in the broader perspective of climate change, the Company appointed a Water Resources Director at the executive level.
In both questionnaires we achieved “B” result (third best score on a scale of eight levels), which is one level above the mining sector average score and the North America region overall score. ​ Additionally, we have participated in the sustainability evaluation carried out by S&P Global through the CSA since 2020.
These include, but are not limited to, the following: ​ ● Sales structure: In the last three years, approximately 79.0% of our revenues have come from the sale of coppe; 10.0% from molybdenum; 5.0% from silver; 3.0% from zinc; and 3.0% from various other products, including gold, sulfuric acid and other materials. ​ ● Copper: In the last quarter of 2022, the LME copper price decreased from an average of $4.40 per pound in the fourth quarter of 2021 to $3.63 (-17.5%), reflecting concerns about a possible recession in the US and Europe, that were partially offset by good news on a possible Chinese recovery.
These include, but are not limited to, the following: ​ ● Sales structure: In the last three years, approximately 77.6% of our revenues came from the sale of copper; 10.9% from molybdenum; 4.2% from silver; 3.1% from zinc; and 4.2% from various other products, including gold, sulfuric acid and other materials. ​ ● Copper: In 2023, representing approximately 76.7% of our sales, the LME copper price increased from an average of $ 3.63 per pound in the fourth quarter of 2022 to $ 3.71 (+2.2%) in the same period of 2023 At the beginning of the last quarter of 2023, we were expecting a market surplus for this year.
This decrease was driven by lower copper (-6.5%), molybdenum (-13.4%) and silver (-1.9%) sales volumes, and by a drop in copper (-5.4% - LME) and silver (-13.6%) prices; this effect was slightly offset by an increase in zinc (+10.5%) sales volumes and by higher prices for molybdenum (+20.0%) and zinc (+16.2%).
This decrease was influenced by lower copper (-3.8% - LME) and zinc (-24.1%) prices, along with a reduction in the sales volumes of silver (-4.3%) and zinc (-1.4%). The aforementioned was partially offset by higher sales volumes for copper (+2.2%) and molybdenum (+2.3%) and an uptick in prices for molybdenum (+27.5%) and silver (+7.6%).
This decrease was due to a reduction in production at our Toquepala (-27.8%; lower grades), Cuajone (-13.5%; lower recovery) and La Caridad (-6.3%; lower recovery) mines; this was offset by an increase in production at our Buenavista operations (+2.8%). ​ Zinc production fell 10.4% in 2022, driven by decreases in production at our Charcas (-16.0%) and Santa Barbara (-11.0%) operations due to lower ore grades. ​ Mined silver production fell 2.1% in 2022 in YoY terms; this was mainly due to a decrease in production at our Toquepala (17.2%), Cuajone (-14.6%) and La Caridad (-6.3%) operations, which was partially offset by an increase in production at the Buenavista (+9.1%) and IMMSA (+2.4%) operations. ​ Please see Management´s Discussion and Analysis of Financial Condition and Results of Operations, Key Matters, Production on the 2021 Form 10-K for details on variations between 2021 and 2020. ​ Operating Cash Costs: An overall benchmark used by us and a common industry metric to measure performance is operating cash costs per pound of copper produced.
This increase was due to higher production at all our mines, with the exception of Toquepala mine (-17.8%), where grades and recoveries dropped. ​ Mined zinc production rose 9.2 % in 2023, driven by increases in production at our Santa Barbara (+29.0%) and Charcas (+9.0%) mines due to higher grades. ​ Mined silver production fell 0.8 % in 2023 in YoY terms; this was mainly due to lower production at our Mexican operations, which was partially offset by an increase in production at our Peruvian operations. ​ Operating Cash Costs: An overall benchmark used by us and a common industry metric to measure performance is operating cash costs per pound of copper produced.
Zinc represented 2.7% of our sales in 2022. ​ ● Production: For 2023, we expect our copper production to reach 925,800 tonnes, an increase of 3.5% over final production in 2022.
Zinc represented 3.0% of our sales in 2023. ​ ● Production: For 2024, we expect our copper production to reach 935,900 tonnes, an increase of 2.7 % over final production in 2023. Last year we drove our Pilares project to full capacity and initiated ramp-up at the Buenavista zinc concentrator.
Molybdenum prices averaged $18.61 per pound in 2022, compared to $15.51 in 2021, a 20.0% increase. ​ Regarding this by-product, we believe that prices will be supported by global supply shortages and strong demand in China and the U.S. ​ ● Silver: We believe that silver prices will have support due to its industrial uses as well as being perceived as a value shelter in times of economic uncertainty.
Molybdenum prices averaged $23.73 per pound in 2023, compared to $18.61 in 2022, a 27.5% increase. ​ For 2024, we believe that prices will hold at the current level of about $19.00 per moly pound reflecting the supply/demand dynamics in a context of lower Asian production. ​ ● Silver: We believe that silver prices will have support due to its industrial uses as well as being perceived as a value shelter in times of economic uncertainty.
