Overview

Endeavour’s fourth and highest-grade silver equivalent mine, El Compas, is located in Zacatecas, the 3rd largest historic silver mining district in Mexico. The fully permitted mine and leased plant were acquired in 2016. Endeavour is currently developing by mechanized, underground, ramp access the El Compas and El Orito veins for production starting in April 2018 and the 500 tpd plant is being refurbished for 325 tpd initially. Since the mine and plant are both scalable, exploration is focused on finding multiple small orebodies to ultimately fill the plant to capacity. A preliminary economic assessment was completed in 2017 (see Endeavour News Release dated March 27, 2017) modeling a 200 tpd operation. Since publishing the PEA, the Company has continued to optimize mining methods, the crushing circuit and grinding alternatives and has been successful on a number of fronts in improving the operating metrics. The information presented below incorporates the improved operating metrics announced in February 2018 (see Endeavour News Release dated February 20, 2018):

Production est. 135,000 oz silver, 11,500 oz gold, 1.0 million silver equivalents per year starting April 2018
Costs Capex est. US$11.3 million, Total cash costs est. $9.09 per Ag Eq oz and All-in sustaining costs est. $9.64 per Ag Eq oz (using 75:1 silver:gold ratio)
Location 1 km south of Zacatecas City
Access Maintained all-weather gravel road
Property 4,217 hectares in three land packages, El Compas, Calicanto, Veta Grande
Infrastructure On power grid, readily available water and labour in Zacatecas
Mine Initial 250 tpd underground, ramp access, mechanized long hole and cut-and-fill mining methods
Plant Initial 375 tpd capacity flotation plant to produce high-grade bulk sulfide concentrates
District Large, multi-vein silver-rich historic district 20 km long by 10 km wide
Resources Two shallow, low sulfidation epithermal vein deposits– Indicated Resources 495,000 oz Ag, 34,900 oz Au, 3.1 million oz Ag Eq; Inferred Resources 530,000 oz Ag, 37,500 oz Au, 3.3 million oz Ag Eq (using 75:1 silver:gold ratio)
Widths 1-5 m, average 2 m
Grades Resource grades: 5.4-7.3 g/t Au, 76-104 g/t Ag in two main veins, El Compas and El Orito
Recoveries est. recoveries >83% gold and >73% silver by gravity and flotation
PEA Robust economic returns at US$18 per oz silver, US$1260 per oz gold, 42% after tax IRR
Potential 10 untested vein targets at El Compas and recently acquired Calicanto and Veta Grande properties have known veins, small historic mines and good exploration potentia
