VANCOUVER, British Columbia, April 18, 2023 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (“Endeavour” or the “Company”) (NYSE: EXK; TSX: EDR) is pleased to announce the Board of Directors (the “ Board ”) of the Company has made the decision to proceed with the construction of an underground mine and mill at the Terronera Project in Jalisco state, Mexico. To date, the Company made significant progress on development activities, with long-lead item procurement well advanced and a seasoned team of development personnel established on the ground. Additional activities include onsite delivery of mobile mining equipment, assembly of initial project infrastructure and advanced earthworks with commencement of underground mine access development. All references to dollars ($) in this news release are in United States dollars.

Project Loan Facility

The Company has entered into a Commitment Letter with Societe Generale and ING Bank N.V. with certain definitive terms agreed to for a senior secured debt facility for up to $120 million (the “ Debt Facility ”). Artemis Capital Advisors has acted as the financial advisor to the Company regarding this transaction, with ING Capital LLC (together with ING BANK N.V. “ ING ”) and Societe Generale acting as Joint Lead Arrangers. A summary of the key terms of the Debt Facility are as follows:

  • Up to $120 million principal amount
  • Term of 8.5 years, including a 2-year grace period during the construction phase
  • Interest rate of US Secured Overnight Financing Rate (“ SOFR ”) + 4.50% per annum prior to completion (SOFR + 3.75% per annum upon completion)
  • First security ranking over the Terronera Project
  • Principal payments are payable in quarterly installments commencing three months after attaining completion of the Terronera Project
  • Cash sweep will be applied to 35% of excess cash flow after debt service from completion onwards until $35 million of loan principal has been prepaid
  • Certain hedging arrangements are required including hedging up to 68,000 ounces of gold over the initial three operating years
  • No hedging requirements apply to the silver production
  • Customary financial and debt servicing covenants

“With official Board approval now in hand, the path is cleared to advance construction of the Terronera Project, which will be Endeavour’s next producing mine,” said Dan Dickson, Endeavour’s CEO. “We are very pleased with the financial commitments that Societe Generale and ING have made towards the development of the Terronera Project. After undergoing a comprehensive due diligence process, we secured very competitive financing terms with quality financiers that protect the upside for our shareholders.”

The Debt Facility will include standard and customary project finance terms and conditions regarding fees and conditions precedent to closing (including satisfaction of remaining customary due diligence and other approvals) and remains subject to the completion and execution of definitive loan documentation. Closing of the transaction is expected to occur in the third quarter of 2023. Further details of the Debt Facility will be released upon signing of the final documentation. Technical, environmental, and social due diligence has been completed by Societe Generale and ING to issue their Commitment Letter.

Prior to the Company securing this commitment, the Board approved early expenditures focused on deliberately advancing the Project in a disciplined manner to de-risk various aspects prior to the final construction decision. Proceeding with these early expenditures has reduced inflationary and timing pressures and has also advanced key work that will facilitate ramp-up to full construction.

Updated Development Plans and Initial Capital Costs

Since the Company filed its feasibility study entitled “NI 43-101 Technical Report on the Feasibility Study of the Terronera Project, Jalisco State, Mexico” dated October 21, 2021 with an effective date of September 9, 2021 (the “ Terronera Feasibility Study ”), the Company has further evaluated various operating scenarios, cost-benefit initiatives and technologies to optimize the Terronera Project’s operating flexibility and economics. Since 2021, additional cost pressures have emerged from systemic inflation and constrained global supply chains, which have contributed to increased costs of inputs within the mining sector. The Company’s move to assemble an experienced development team has worked to mitigate some of these impacts, and management believes the Company is well-equipped to navigate the current business environment.

Management recommended and the Board has approved the construction of an optimized Terronera Project scenario (the “Revised Scenario”), consisting of a process plant with 2,000 tonne per day (tpd) capacity and an initial capital expenditure cost of $230 million, partially offset by a decrease in sustaining capital to $88.3 million over the life of the mine.  Endeavour expects a 21-month construction period, including 3 to 6 months ramp up to full production with initial production expected in the fourth quarter of 2024.

Total (Direct & Indirect) $175.0 $105.6 $280.6 $230.4 $88.3 $318.7 $38.1 14%

The increased operating scale and optimization should result in slightly lower operating costs on a per tonne basis compared to the Terronera Feasibility Study. Below is a summary of the optimization work that has been completed on the project cost structure and key components:

  • The mine design has been redesigned and mine plan optimized to reduce initial underground mine access development including changing portal locations. These changes were aimed at increasing development efficiencies, improving early ventilation, and reducing surface haulage. Pre-production development quantities increased for scaling the mine to 2,000 tpd.
  • The processing plant and tailing storage facility initial capital expenditures have increased primarily for equipment required to achieve 2,000 tpd. These include a SAG Mill, concentrate regrind, and an additional tailings filter. Additional increases have resulted from inflationary costs for steel and other required materials for construction. Further metallurgical testing completed during the basic engineering design phase for the process plant indicate increased estimated silver and gold recoveries by 1.6% and 2.5% respectively, compared to the recoveries in the Terronera Feasibility Study. Certain sustaining capital costs in the Terronera Feasibility Study are now included as operating costs.
  • Site infrastructure now includes the Company’s ownership of the liquified natural gas (“ LNG ”) vaporization and power generation equipment rather than leasing, which was included as an operating lease in the Terronera Feasibility Study. The site infrastructure increase from the Terronera Feasibility Study is also due to additional access road improvements.
  • The owner’s costs, project indirect costs and contingency increased based on updated estimates of detailed engineering and overhead expenses. The contingency estimate was revised based on updated quotes and increased confidence in certain estimates and committed costs to date.

“The optimization work on the Project over the past year has captured opportunities for higher throughput and improved metallurgical recoveries. At the same time, technical risks have been mitigated by further study, engineering, testing and early works,” said Don Gray, Endeavour’s COO. “Overall, we are very fortunate we started with pre-development activities well in advance of this construction decision. This has significantly de-risked the Project, as we have been able to secure several procurement contracts before certain inflationary cost spikes and supply chain constraints. Like others in the industry, we are dealing with inflation on the remaining unawarded work. However, such inflation affects a smaller portion of the overall Terronera Project.”

The Company is well-financed to satisfy the financing requirements of the Project, having already invested over $58 million in direct development expenditures to the end of Q1 2023. However, the Company may consider various additional alternatives to raise the required projected capital as required by the terms of the Debt Facility, including a potential cost overrun facility. The revised metrics for the 2,000 tpd plant as compared to the 1,700 tpd plant contained in the 2021 Terronera Feasibility Study are set out in the following table. The Company does not consider these changes to be material to the Company.

Community Activities

The Company’s Terronera community relations team maintains an active community relations program, social engagement programs and environmental management program. A recruitment campaign has been initiated to hire local workers from communities in the direct area of influence within the region and a training program for locals is in development to prioritize the hiring of locals. Additionally, the team has held, and continues to hold, multi-stakeholder meetings with different levels of government.

Local municipal and ejido authorities are very supportive of the Terronera Project, which they view as a welcome source of employment for hundreds of people from the surrounding communities. They recognize that the Company will bring skilled employment to this region and create opportunities for local sub-contractors, suppliers and other service providers.

In addition, to ensure responsible development of the Terronera Project, the Company is adhering to the Equator Principles (“ EP4 ”), a risk management framework that helps ensure that large scale development or construction projects appropriately consider potential impacts on society and the environment. As part of the process, we have been working on the management plans for procurement, community relations, environment, risk control, and health and safety for the various stages of construction. We will complete the environmental and social impact assessment in early 2024, which will identify impacts on the different stages of the Project. For more details on how the Company is applying EP4, you can learn more on the Company blog here .
