(PresseBox) - Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR - https://www.commodity-tv.com/play/endeavour-silver-virtual-roadshow-investor-presentation/ ) announces that the Company?s recent re-assessment of all aspects of the Terronera Mine Project in Jalisco state, Mexico has resulted in more robust economics in the final Pre-Feasibility Study (?2020 PFS?) compared to the earlier Pre-Feasibility Study released on August 30, 2018 (?2018 PFS?).

Endeavour management worked with Ausenco Engineering Canada Inc. (Ausenco) on the re-conceptualization and re-engineering of the project to generate the significantly improved 2020 PFS economics presented herein. Ausenco will co-author the 2020 PFS Technical Report in compliance with National Instrument 43-101, to be filed on SEDAR and EDGAR within 45 days of this news release. All currency references herein are in US$.

The PFS base case assumes a two-year trailing average silver price of $15.97 per ounce (?oz?) and a gold price of $1,419 per oz with an implied 89:1 silver:gold ratio, and an MXN:USD exchange rate of 20:1. The 2020 PFS also presents an alternative spot case using the closing metal prices as of July 8th, 2020, with silver at $18.49 per oz and gold at $1,812 per oz for a silver: gold ratio of 98:1.

Additional details and charts can be found in the NI 43-101 Technical Report which will be posted on SEDAR and the 2020 PFS webinar presentation available (here) on the Company website.

LOM Mine-Site All-in Sustaining Cost (?MAISC?) of $($2.06) per oz silver, net of the gold credit

Payback of 1.7 years

Pre-tax cumulative undiscounted free cash flow of $514 million

After-tax cumulative undiscounted free cash flow of $342 million

Bradford Cooke, CEO, commented, ?This final iteration of our Terronera PFS adds real value to the project, reducing the initial development capex and significantly enhancing our financial returns.

?At base case prices, the improved economics include an NPV of $137 million, IRR of 30.0%, and payback period of 2.7 years. At current spot prices, the project exhibits the exceptional economics that one would expect from such a shallow, thick and rich silver-gold vein system. Endeavour now plans to complete a Feasibility Study at an estimated cost of $1.8 million over the next 12 months. Terronera represents our next core asset and once built, should become our largest and lowest cost mine.?

Location, Access, Physiography, Infrastructure

Terronera is located approximately 50 kilometres (km) northeast of the port city of Puerto Vallarta in Jalisco state, Mexico, about a 1water wells, more power capacity and employee camps will be required.

Property, History, Geology, Mineralization

Terronera consists of 24 mineral concessions totalling 17,369 hectares. o Mexico acquired the project and conducted some exploration work in the late 1980?s and early 1990?s.

Endeavour acquired an option from Grupo Mexico to purchase Terronera for $2.75 million in 2010, and all expenditures since inception including exploration and engineering to date total $27.8 million. cur within late Cretaceous andesite to rhyolite volcanic rocks within the Sierra Madre Occidental metallogenic belt where it transects the Trans-Mexico Volcanic Belt.

Reserves and Resources

The 2020 PFS provides a revised mine plan, including revised mining dilution and recovery assumptions, which resulted in slight reductions to tonnes, grades and oz in the December 31, 2019 Mineral Reserve Estimate. from the 2018 PFS Mineral Reserve Estimate include tonnes up 18%, silver grade down 10%, gold grade up 0.4%, silver oz up 6.5% and gold oz up 20%, mainly due to infill drilling of the Terronera and La Luz Inferred Mineral Resources to upgrade them to Probable Mineral Reserves.

Initial and Sustaining Capital

The initial capital cost of the project is $99 million, to be incurred over an 18 month period prior to the start of commercial production. Initial capital is 14% lower than the 2018 PFS due to reducing initial mine development and equipment, reducing the plant footprint, updating the plant flowsheet, utilizing some used plant equipment from El Cubo, modifying the tailings storage facility and moving some capex into sustaining capital through lease financing. Cumulative sustaining capital is estimated at $60 million with over 80% spent in years 1-4 for the phased underground mine development.

Operating, Cash and All-in Sustaining Costs

The average annual operating cost per tonne is $83.82, or about 7% higher than the 2018 PFS due mainly to higher processing costs and smelter charges.

EBITDA and FCF

The average annual EBITDA during commercial production is $48 million and after-tax free cash flow is $31 million. The cumulative LOM EBITDA and after-tax free cash flow are estimated at $476 million and $217 million, respectively 6% and 13% higher than the 2018 PFS.

Project Sensitivities

At current spot prices, the after tax NPV and IRR are most sensitive to metal prices and least sensitive to initial capex and has approximately equal exposure to silver and gold prices.

Mining Operations

Both Terronera and La Luz will be mechanized ramp access underground mines capable of producing an average of 1,600 tpd to meet the plant capacity. and backfill inside the mine to minimize transport cost.

Plant Flowsheet

The plant flowsheet with a 1,600 tpd capacity, consists of three stage crushing, grinding, flotation (flash, rougher, scavenger and cleaner), thickening and filtration of concentrate, tailings filter plant and a filtered-tailings (dry stack) storage facility. Plant operations were also improved to reduce capital. pacity by 7%, simplifying the flowsheet, better utilizing equipment and reducing the power consumption and cost.

Surface Infrastructure

Surface infrastructure to be constructed at Terronera includes conventional gravel roads, underground haul roads, power generation plant, reclaim and fresh-water dams, waste and ore stockpiles, ancillary buildings, communications and camp facilities. The estimated power requirement for the project is 4.9MW and an additional 1MW for the camp. The power to the camp will be provided either by the national grid, CFE or as part of the project power supply which will be powered through a liquified natural gas generating station in tandem with a solar power plant built and maintained by a Mexican power provider.

Project Schedule

Management now plans to proceed with a Feasibility Study over the next 12 months at an estimated cost of $1.8 million to further de-risk the project and access additional project debt financing alternatives. Once a development decision is made, the Terronera Project will take approximately 18 months to construct and commission to commercial production.

Sustainability Initiatives

The Community Relations team has been successful in mitigating risk and obtaining support from the local communities, mainly focusing on the two closest towns, Santiago de los Pinos and San Sebastian del Oeste (combined population of 1,250). The Company has completed the following initiatives:

Social Impact Assessment - 82.6% of the people surveyed agreed with mining activities in the area and support job creation and positive economic benefits that will result from mining

Social Management System - designed to build and maintain positive relationships in the communities, including a Social Grievance Mechanism designed to receive, investigate and respond to complaints and concerns in the local communities.

Urban Development Project - developing a Municipal Urban Plan to facilitate the influx of employees, contractors, suppliers and other stakeholders for the life of mine, including essential infrastructure (water supply, water treatment, roads, accommodations, etc.

Government Engagement - through agreements with local, municipal, state and federal ministries to develop cultural, educational, health, family, employment and other programs in the community

Ejido Engagement ? through agreements with the communal land association to provide access across their land during the exploration, development and exploitation

Government Permits

Endeavour Silver has in place the following government permits for the development of the Project:

Mine and plant permits (received Q3, 2017)

Tailings and dumps permit (received Q2, 2019)

MIA (EIS) from SEMARNAT (Mexican Environmental Authority) previously received in Q1, 2017, is being extended.

Additional permit applications will be filed as needed based on the Feasibility Study

Exploration Potential

Exploration at Terronera has identified several areas of interest with high discovery potential. The main Terronera and La Luz Vein orebodies are both open to a certain extent to surface and at depth.

The La Loma-Los Pajaros Veins located close to the footwall of the Terronera Vein have returned economic grades over mineable widths from surface rock chip sampling, however they have not yet been drilled.

In the Real Alto area, more than 12 veins have been identified. Real Alto is located about 20 km at southeast of the Terronera Vein at elevations 500 to 600 m higher than the Terronera orebody. These vein structures are hosted in the same favorable volcanic rock formations and with the same structural patterns as Terronera. These vein targets range from 500 m to 1,000 m long with previous rock chip and shallow drill results returning up to 150 gpt Ag.

Opportunities to Enhance Value

Several opportunities to enhance value for the Terronera Project have been identified and will be further evaluated during the Feasibility Study.

Expand Property Size ? complete the process of applying for new concessions and acquiring existing third-party concessions covering mineralized areas proximal to the current properties

Expand Mineral Resources and Reserves ? plan additional exploration drilling, both within the current resource footprint to convert Inferred Mineral Resources to Probable Reserves, and to test multiple other veins such as the La Loma-Los Pajaros and Real Alto Vein systems

Expand Mine and Plant ? evaluate the potential to expand to 2,000 tpd subject to expanding the Mineral Reserves

Optimize Mining Method ? with more geotechnical drilling, additional long hole mining may be possible, current model assumes a combination of long hole mining (in thicker zones with stronger wall-rocks), cut and fill mining (in narrower zones with weaker wall-rocks) and resuing (in very narrow high grade veins)

Optimize Ore Transport ? evaluate an automated underground rail haulage system to haul ore to the plant which would benefit both haulage costs and ventilation requirements

Optimize Mining Equipment ? evaluate electric equipment instead of diesel which would benefit both fuel costs and ventilation requirements

Optimize Metallurgical Recoveries ? continue to evaluate grind sizes vs flotation stages vs metal recovery

Reduce Operating Costs ? Evaluate pre-concentration technologies to reduce the unit operating costs

Optimize Tailings Transport ? evaluate alternatives such as conveyor or pipeline vs trucks to move tailings from the plant to the dry stack storage facility

Optimize Power Capacity ? re-evaluate power needs once other power applications are optimized

Next Steps

Endeavour plans to complete a Feasibility Study (FS) for the Terronera Project with some activities as overlapping instead of sequenced.

Feasibility Study - Consultant bidding and selection process is already underway and scheduled to conclude in August. The Feasibility Study is estimated to take 9 to 12 months.

EPC Process - Endeavour has defined its EPC strategy and initiated contacts with potential contractors to commence the process of contractor bidding and selection process for the project engineering, procurement and construction.

Government Permitting ? some permits such as mine access ramp portals, temporary waste rock storage areas and construction camp will be modified now the PFS is concluded, but these are not expected to delay the construction phase

Long Lead Items ? Endeavour has received and warehoused the main ball mill components and will evaluate the possibility to commence early underground development of the main three km long haulage-way to access the main Terronera orebody

Project Financing ? continue to evaluate staged financing, with current cash and ATM to fund the FS and long lead items, and debt, convertible, equity and other alternatives to fund the initial capex
