Endeavour Silver Updates Progress on Terronera Silver-Gold Mine Project in Jalisco, Mexico
Endeavour Silver Corp. (NYSE: EXK, TSX: EDR - https://www.youtube.com/watch?v=wmK8Kyb4AX0&t=1s) provides herein an update on its Terronera silver-gold mine project, located in Jalisco state, Mexico. Since the release of the initial Pre-Feasibility Study (?PFS?) one year ago (see Endeavour News Release dated April 3, 2017), Endeavour has conducted a number of engineering trade-off studies to refine the operating parameters and optimize the economic performance of the project.
Bradford Cooke, Endeavour CEO commented, ?We have made very good progress in enhancing many of the operating parameters and developing our working knowledge of this proposed mine.
Endeavour retained a number of engineering consulting firms to work with Endeavour?s technical services group in preparing and updating the PFS.&E Mining Consultants prepared and are currently refining the Mineral Resource and Reserve estimates and mine plans for the Terronera and La Luz veins.
Highlights of Project Engineering Studies on Operating Parameters
Optimal throughput based on current Mineral Reserves and Resources is 1500 tonnes per day (?tpd?)
Optimal development plan based on time needed to develop the mine is two stages of 750 tpd each
Annual production at 1500 tpd is estimated at 5.0 million oz silver equivalents per year (at a 75:1 silver:gold ratio) based on 300 grams per tonne (?gpt?) net payable silver equivalents per tonne (still being optimized)
Mineral Resource model updated to include the small but very high grade La Luz vein (still being optimized)
Mine plan is initially 100% cut and fill in the Terronera vein due to weak rock strength in the vein and 100% resuing in the narrow La Luz vein (still being optimized)
Plant design is crush, grind, flash flotation, regrind and conventional flotation to produce a single bulk sulfide silver-gold concentrate
Tailings facility is dry stack so that the process water is recycled for minimum water consumption and maximum tailings stability
Power generation alternatives are electric power grid or compressed natural gas with diesel backup (still being optimized)
Geotechnical studies were completed for the mine, plant and tailings sites
Hydrological studies were completed around the mine, plant and tailings sites
Metallurgical studies were refined to provide a simpler process flowsheet and plant design
Indigenous studies were completed for the region
Public road upgrade study was completed in consultation with the local communities
Project offices and housing site and plan including solar power approved by local community
Land acquisition agreements completed for the mine, plant and tailings areas
Final mine and plant permits received August 2017, mine and plant bond posted February 2018
Activities to Finalize Updated PFS
Complete review of Mineral Reserve and Resource model
Complete optimization of mine plan
Complete review of power options
Complete review of explosives permit alternatives
Finalize economic model
Receive dumps and tailings permits
For several years, we have maintained good relations and an open dialogue with the local communities on our annual work plans.
We held meetings with community leaders to update them and receive their input into our plans to develop, operate and reclaim the Terronera mine and related facilities.
We took senior community representatives to one of our mines so they could see first-hand how we operate and what our mines look like.
We took community members who wanted to learn how to become miners to one of our mines for training in a variety of job opportunities.
We offer employment and hire locally whenever possible to improve the economic outlook and skills capacity in the local communities.
We plan to hire local contractors whenever possible if they have the right equipment for opportunities such as building site and road construction.
We plan to employ approximately 350 people during the plant construction and about 500 people in total for commercial operations.
We reclaim disturbed areas each year and as a result, we have planted approximately 57,150 trees in the area.
Years ago, we established a wild deer farm and we continue to support it as part of our environmental strategy for the area.
Exploration Opportunities for Further PFS Optimization
The 2018, 5,400 meter exploration drill program is now underway with one drill rig targeting the southeast extension of the Terronera vein, and a second underground drill rig is planned to test the Quiteria vein at depth below the Quiteria mine.
A new infill drill program of up to 10,000 meters in up to 25 holes was recently approved to upgrade the inferred resources to indicated resources, mainly at depth in the Terronera vein and to a lesser extent in the La Luz vein, which should benefit the net present value (NPV) and internal rate of return (IRR).
