Coeur Reports Year-End 2021 Mineral Reserves and Resources

16.02.2022  |  Business Wire

Expansion drilling success drives strong resource growth

Coeur Mining Inc. ("Coeur" or the "Company") (NYSE: CDE) today reported year-end 2021 proven and probable reserves of 3.1 million ounces of gold, 238.2 million ounces of silver, 296.1 million pounds of zinc and 193.2 million pounds of lead. Year-over-year gold reserves were essentially unchanged, net of depletion, driven by a higher cut-off grade assumption at Rochester offset by increases at Wharf and Palmarejo. Year-over-year silver reserves decreased due primarily to the higher cut-off grade applied at Rochester partially offset by an increase at Palmarejo.

Measured and indicated resources totaled 3.4 million ounces of gold, 285.0 million ounces of silver, 589.4 million pounds of zinc and 312.6 million pounds of lead, reflecting double-digit year-over-year increases across all metals driven by additions from Palmarejo, Silvertip and Kensington.

Inferred resources were 2.7 million ounces of gold, 91.2 million ounces of silver, 422.3 million pounds of zinc and 200.7 million pounds of lead. Year-over-year gold and silver inferred resources declined due to the higher cut-off grade assumption used at Rochester, partially offset by increases at Kensington and Wharf. Silvertip's silver, zinc and lead inferred resources increased 48%, 37% and 40%, respectively.


Key Highlights1

  • Success from five-year, nearly $240 million investment in exploration - Infill-focused drilling programs successfully replaced 1.8 million and 56.4 million ounces of cumulative gold and silver production, respectively, as well as added an additional 0.5 million ounces of gold and 85.4 million ounces of silver reserves. Expansion-focused drilling programs successfully added 1.7 million and 113.4 million ounces of measured and indicated gold and silver resources, respectively, and an additional 1.8 million and 31.9 million ounces of new inferred gold and silver resources, respectively
  • Resource conversions at Palmarejo and Wharf led to reserve increases net of depletion - Successful infill drilling in the Hidalgo Zone at Palmarejo drove reserve increases in gold and silver of approximately 4% and 5%, respectively, in 2021. A roughly 18% increase in gold reserves at Wharf has added two years to its mine life, further enhancing the overall return on investment from the initial $99 million cash acquisition in 2015
  • Significant high-grade resource increase at Silvertip - Silver, zinc and lead measured and indicated resources increased year-over-year by approximately 51%, 33% and 44%, respectively, at the Silvertip property in British Columbia. Silver, zinc and lead inferred resources grew by roughly 48%, 37% and 40%, respectively, during the same period
  • Updated reserves at Rochester support robust, 13-year reserve-only mine life in the top mining jurisdiction in the world - The Company raised its cut-off grade assumption to reflect higher anticipated operating costs and updated gold and silver recovery assumptions as part of its recently completed re-baselined Rochester expansion project review
  • Sterling and Crown properties in southern Nevada remain a key area of focus in 2022 - Resources remain relatively unchanged following a significant lag in assay results due to assay laboratory delays experienced throughout 2021. The Company is beginning to receive assay results from the 2021 campaign with encouraging drill results from C-Horst, SNA, Daisy and Secret Pass. Infill and expansion drilling is planned to continue throughout 2022 with the goal of an updated resource at Crown zone, including a maiden resource for the C-Horst discovery at year-end

"One of the largest ongoing multi-year exploration campaigns in the precious metals sector continued to drive organic growth throughout our portfolio of diversified North American assets," said Mitchell J. Krebs, Coeur's President and Chief Executive Officer. "Over the last five years, Coeur has invested approximately $240 million in exploration capped off by our largest program in Company history last year, totaling $71 million. This elevated level of investment in exploration during the five-year period - nearly 73% focused on resource expansion programs - has dramatically increased our inventory of reserves and resources, which we expect will translate into longer mine lives and attractive returns in coming years.

"We plan to invest an additional $40 million Companywide of exploration in 2022 - approximately half focused on infill drilling and half on resource expansion drilling - in an effort to realize further reserve and resource additions throughout Coeur's long-lived asset portfolio. These priorities include the follow-up of recent exploration success targeting higher-grade gold zones at West Rochester with the potential to be incorporated into future mine plans for the expanded Rochester operation. In addition, we will maintain an aggressive drilling program at Silvertip. With continued exploration success, coupled with successful study work in support of a larger scale operation, Silvertip holds the potential to be Coeur's next growth driver following the completion of the Rochester expansion."

Notes

The potential quantity and grade for the deposits described herein are conceptual in nature. There is insufficient exploratory work to define a mineral resource and it is uncertain if further exploration will result in the applicable target being delineated as a mineral resource.

  1. 2021 reserves and resources were determined in accordance with Item 1300 of SEC Regulation S-K. Reserves and resources for prior periods were determined in accordance with Canadian National Instrument 43-101. Both sets of reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but the standards embody slightly different approaches and definitions.
  2. Gold equivalence assumes gold-to-silver, -lead, -zinc ratios of 1:60, 1:1,200 and 1:1,000, respectively.

Rochester Mineral Resource estimates are tabulated within confining pit shells that uses the following input parameters: oxide gold recovery of 77.7%-93.7% and silver recovery with range of 59%-61%; sulfide gold recovery range of 15.2%-77.7% and silver recovery with range of 0.0%-59% with a net smelter return cutoff of US$2.55-US$3.70/ton oxide and US$2.65/ton sulfide, where the NSR is calculated as resource net smelter return (NSR) = silver grade (oz/ton) * silver recovery (%) * silver price ($/oz) - refining cost ($/oz) + gold grade (oz/ton) * gold recovery (%) * gold price ($/oz) - refining cost ($/oz); and variable pit slope angles that approximately average 43º over the life-of-mine.
  7. Silvertip Underground Mineral Resource estimates are reported using a net smelter return ("NSR") cutoff of US$130/tonne. Mineral Resources are reported insitu using the following assumptions: The estimate use the following key input parameters: lead recovery of 87-88%, zinc recovery of 81-82% and silver recovery of 88-89 %. Lead concentrate grade of 51-53%; zinc concentrate grade of 48-50%; mining costs of US$68.77/tonne; processing costs of US$58.20/tonne and US$46.49/tonne, where the NSR ($/tonne) = tonnes x grade x metal prices x metallurgical recoveries - royalties - TCRCs - transport costs over the life of the mine.
  8. Sterling Open Pit Mineral Resource estimates are reported in-situ and are contained within a confining pit shell and use the following key input parameters: reported above a gold cutoff of 0.007 ounces per ton; gold recoveries of 75-80%; mining costs of US$2.16/ton; process costs of US$2.70/ton; G&A costs of $1.00/ton; variable pit slope angles of 39-52º over the life-of-mine.
  9. La Preciosa Open Pit Mineral Resource estimate is reported using a net smelter return ("NSR") cutoff of US$23/tonne and Underground Mineral Resources are reported using a NSR cut-off of $71/tonne. Mineral Resources are reported in-situ and contained within a conceptual measured, indicated and inferred optimized pit shell or conceptual underground mining shapes using the following assumptions: silver price of US$20/oz, gold price of US$1,400/oz. Average silver and gold recovery are 82% and 69%, respectively. Open pit mining cost is US$1.85/tonne, underground mining cost is US$47.96/tonne, processing cost is US$17.53/tonne and G&A cost is US$5.54/tonne. Mineral resources include hanging and footwall dilution, and typical mining recovery is estimated to be 95%. The technical and economic parameters are those that were used in the 2017 Resource Estimation. Based on the QPs review of the estimate, there would be no material change to the Mineral Resource if a gold price of US$1,700/oz, a silver price of US$22/oz or economic parameters were updated. Therefore the 2017 Mineral Resource report is considered current and is presented unchanged.
  10. Lincoln Hill Open Pit Mineral Resource estimate is reported in-situ and are contained within a confining pit shell and use the following key input parameters: reported above an oxide gold equivalent cutoff of 0.15 ounces per ton and 0.20 oz ounces per ton assuming a silver to gold ratio of 60:1; gold recoveries of 64%; silver recoveries of 59%; mining costs of US$3.10/ton; process costs of US$3.60/ton; general and administrative costs of $1.50/ton processed; average pit slope angles of 45º over the life-of-mine. The technical and economic parameters are those that were used in the 2018 Resource Estimation. Based on the QPs review of the estimate, there would be no material change to the Mineral Resource if a gold price of US$1,700/oz, a silver price of US$22/oz or economic parameters were updated. Therefore the 2018 Mineral Resource is considered current and is presented unchanged.
  11. Wilco Open Pit Mineral Resource estimates are reported using an equivalent gold cutoff of 0.20 ounces per ton assuming a silver to gold ratio of 60:1. Resources are reported in-situ and contained withed a conceptual measured, indicated and inferred optimized pit shell. Silver price of US$20/oz, gold price of US$1,400/oz. Average oxide and sulfide gold recovery is 70%, average carbonaceous gold recovery is 50%. Average oxide and sulfide gold recovery is 60%. Average carbonaceous silver recovery is 50%. Open pit mining cost is US$1.50/ton, processing and processing and G&A cost is US$5.46/ton; average pit slope angles of 50º. The technical and economic parameters are those that were used in the 2018 Resource Estimation. Based on the QPs review of the estimate, there would be no material change to the Mineral Resource if a gold price of US$1,700/oz, a silver price of US$22/oz or economic parameters were updated. Therefore the 2018 Mineral Resource report is considered current and is presented unchanged.
