VANCOUVER, British Columbia, Oct. 21, 2024 -- Endeavour Silver Corp. ("Endeavour" or the "Company") (NYSE:
EXK; TSX: EDR) is pleased to provide a Q3 2024 construction progress update for its Terronera Project in Jalisco state,
Mexico. A photo gallery presentation accompanies this news release and can be found here or on the Company website at
Terronera Project Progress Photos . All dollar ($) references in this news release are in United States dollars.
The Terronera project made substantial progress during the third quarter as the Upper Plant Platform nears completion.
Surface mill and infrastructure construction reached 90%, further preparing for advancement into operations. Focus continues
on the Lower Platform, where concrete work is well underway, and the Tailing Storage Facility, with underdrain embankment fill
and pipe installation advancing at a good pace.
“We’re in the final construction phase with the finish line in sight,” commented Don Gray, Chief Operating Officer. “The Upper
Platform is nearly complete, and the primary jaw crusher was commissioned, with rock crushed in August. The major focus is
the Lower Platform and Tailing Storage Facility. Our dedicated Terronera team continues to meet the challenges both for
developing the mine and constructing the mill facilities to keep the project on track to begin commissioning systems near the
end of Q4.”
Q3 2024 Construction and Development Highlights
As of September 30, 2024, site works and activities included:
• Safety – Health and safety for operational readiness is underway. The mine rescue equipment arrived, and team
members are being recruited and trained. Two refuge stations were installed.
• Community Relations – Local community support continues to be a priority. In Q3, the Company supported a series of
local initiatives and investments such as: a municipal cooperative agreement; inauguration of an early-childhood
development center; scholarships for university students in Santiago de Pinos; municipal road maintenance; workshops
for business entrepreneurship for local residents; environmental education program for primary schools; community tree
donation; and summer community workshops for children and youth.
• Progress – Overall project progress (mine development and surface construction) reached 77% completion, with more
than $258 million 1 of the project's budget spent to date. Project commitments total $270 million 1,2, 99% of the $271
million capital budget.
• Mine Development – During the third quarter, 1,051 metres were developed underground for a project total of 5,544
metres. Furthermore:
◦ Underground explosive magazines were completed and the explosive use permit application was submitted for
approval, which is anticipated in Q4 2024.
◦ Terronera main sump and pump station excavation and support were completed.
◦ Development was nearly complete for the test stope that will be used to verify stope design criteria including
opening span widths, length and height as well as establishing longhole drilling, blasting and backfill procedures.
◦ Development ore was stockpiled on surface.
◦ Slashing of an existing portal commenced for access to mine the high-gold grade La Luz vein, which is
anticipated to be reached in H1 2025.
• Upper Plant Platform Site – Mill and surface infrastructure construction was 90% complete and continues to transition
to operations.
◦ Primary Crusher – Primary jaw crusher was commissioned with rock crushed in August, marking a major project
milestone.
◦ Coarse Ore Stockpile and Reclaim ("COS") Tunnel – Reached 100% completion and pre-commissioning tests
commenced.
◦ Grinding and Thickening – Piping, mechanical, electrical, and instrumentation are expected to be completed in
October.
◦ Flotation – Compressor pressure vessel and air dryer systems were installed with piping connections in
progress. Flotation equipment, including blowers, instrument, and valve installations are ongoing and scheduled
for Q4 completion.
◦ Raw and Process Water Tanks – Steel rings are in place and welding was over 90% complete. Inlet, outlet and
access port installations, final weld testing, sand blast/mechanical cleaning, and painting are scheduled for
completion in Q4.
• Lower Facilities Platform and Tailing Storage Facility (TSF) – Lower Platform area was nearly 30% complete. Focus
has been on completing the last section of the tailing filter bearing wall prior to starting the filter support deck; the first
structural steel columns and beams were erected for the Concentration Filter building and equipment mechanical
structures.
◦ Main Embankment TSF – Excavation for the main embankment key trench was 100% complete, the secondary
key was at 40% complete, and underdrain piping placement has been completed.
◦ Tailing Filtration Area – More than 75% of the floor slab and 100% of the filter bearing wall for the tailing filter
building has been poured. The tailing filters, which are stored at the Puerto Vallarta warehouse, are schedule to
be transported to site for Q4 2024 installation.
◦ Concentrate Filter Area – More than 80% of the floor slab and 75% of the pipe rack and equipment foundations
in the concentrate filter area has been poured, and tank foundations and equipment pedestals were nearly
complete.
• Auxiliary Buildings – Laboratory and Plant Maintenance buildings reached 40% of completion.
◦ Laboratory Building – Majority of the sheathing and insulation have been installed and steel studs are in place.
Sheetrock and compressor and dryer installations are in progress.
◦ Plant Maintenance Building – Structural steel installation started in late September.
• Procurement –The project team continues to expedite pending arrivals. Procurement was 99% complete.
• Onsite Personnel – At the end of Q3, the workforce increased to over 250 Endeavour Silver employees and over 800
contract workers, with the total number expected to decrease in Q4 2024 as commissioning begins.
Next Steps and Planning
The Terronera Project is tracking to begin commissioning systems near the end of Q4.
For Q4 2024, the tailing filter area, which was turned over to the mechanical contractor in early October, will allow focus on
installing at least one tailing filter along with the concentrate filter using an extended work schedule to allow initial systems
commissioning anticipated near the end of Q4. Grinding, flotation, and thickening systems will be mechanically completed in
late October, allowing testing and ramp-up of these circuits to begin in November and December.
Mine development in Portals 1, 2, and 4 declines will continue, with longhole stopes being developed and initial production
planned for Q4; ore will continue to be stockpiled for mill ramp-up. At La Luz, the portal is being constructed, and the orebody
ramp access will advance in Q4.
The critical path remains the TSF, tailing concentrate filters construction, and the advancing underground mine.
