“During Q3, we’ve made notable progress in a number of key areas,” commented Don Gray, Chief Operating Officer. “Not only have we completed construction of our permanent camp and can now fully accommodate our workforce, but we’ve also made significant progress on construction of our process plant. Our procurement efforts are on schedule, with most long-lead major equipment anticipated to be received by year’s end. With our underground mine development, we’re seeing a noticeable increase in rates, as our mining team is now advancing four working faces simultaneously. We’re pleased with Terronera’s progress to date as we expedite completion of this next core asset.”

Q3 2023 Construction and Development Highlights

Early works, initiated in the first quarter of 2022, have rapidly advanced, with more than $95 million of the project’s budget spent to date. Overall construction progress is 38% complete. Project commitments total $160 million, which is 69% of the $230.4 million capital budget. The project remains on track and on budget for initial production in Q4 2024. As of September 30, 2023, site works and activities have included:

  • Safety – Our strong safety focus at site continues. Key safety initiatives have included improved accident investigation procedures, accident prevention measures, and development of on-site emergency brigade. During the recent annual rainy season, hazard lightning control measures were reinforced.
  • Engineering – Total engineering progress is 97% complete. The mine waste rock dump design is nearing completion. Final design for the tailing storage facility as well as the filters, LNG and warehouse areas is pending completion of geotechnical site investigation.
  • Access Road Construction –Site road access is now established following extensive improvements over the last year. Equipment access and material deliveries to site remained unaffected during the annual rainy season.
  • Permanent Camp – All permanent camp dormitory units have been installed for accommodation of 550 personnel. Fully operational facilities include the dining, laundry, medical clinic, and training areas.
  • Mine Development – During Q3, Portal 1 mine yard excavation reached the design elevation of 1,475 metres allowing mine development to advance on four fronts: Portal 1, Portal 2, and Portal 4 (incline & decline). Over 1,300 metres of underground development have been completed through to Q3. As planned, mining advance rates increased as Portals 2 and 4 passed through the fault zone and ground conditions improved.
  • Plant Site – Concrete work and rebar installation continued in the SAG and ball mill grinding, coarse ore stockpile and flotation areas, and concrete work began for the primary crusher. Excavation work started in the tailing thickener area.
  • Procurement – Most long-lead major equipment is anticipated to be received by year’s end. Purchase order contracts were executed for initial structural steel support. During Q3, the request for bid proposal for the mill construction contract was released, which includes structural steel, mechanical, piping, electrical and instrumentation.
  • Onsite Personnel – The workforce has increased to 91 employees and 430 contractor workers.
  • Community Relations – During Q3, community relations focused on local municipality support to maintain and improve municipal roads from the state highway to the site area, as well as assistance with a municipal landfill facility. Additionally, local community suppliers continued to be integrated into the Terronera value chain. Summer initiatives included several cultural and sports activities.
  • Environmental – Environmental and social assessment initiatives continued as outlined under the Equator Principal requirements set forth within the project loan financing. Items completed during Q3 included the flora and fauna baseline study, integrated pest management plan, rainy season biodiversity monitoring, and the visual baseline report. In addition, development of a comprehensive reclamation and closure program is in progress.
  • Liquidity – Upon execution of a credit agreement for a $120 million senior secured debt facility, the Company is well-positioned to satisfy the financing requirements of the project (see news release dated October 10, 2023 ). It is expected that Project commitments will total nearly 100% of the $230.4 million budget in early Q2 2024.
