Bruner represents an advanced stage precious metals exploration opportunity in Nevada with potential for district acquisitions and near-term organic growth

The Bruner Gold Project is an exploration project located approximately 180 km southeast of Reno, Nevada. Gold was originally discovered in the district in 1906 and saw intermittent historic mining between 1906 and 1998. Endeavour Silver completed the acquisition of the Bruner property in 2021 (see news released dated September 1, 2021) which includes mineral claims, mining rights, property assets, water rights, and government authorizations and permits.

Recent exploration activities by previous operators included mapping, drilling, geophysical surveys and sampling culminating in a mineral resource estimate in 2015 and a preliminary economic assessment in 2017 outlining a low capital cost, open pit, heap leach operation. A historic resource estimate of 342,000 ounces of gold contained in 17.5 million tonnes grading 0.61 gpt in three zones, Paymaster, HRA and Penelas was prepared for Canamex in a technical report dated January 22, 2018 titled “NI 43-101 Technical Report on the Bruner Gold Project, Updated Preliminary Economic Assessment, Nye County, Nevada, USA” by Welsh Hagen Associates. Endeavour is not treating the historical estimate as a current mineral resource or mineral reserve and has not verified the historical resource estimate and is not relying on it. Endeavour plans to “twin” certain drill holes and conduct a drilling program to upgrade the historical estimate as a current mineral resource in 2022.

Location & Infrastructure	Located within Nevada’s Walker Lane northwest trending mineral belt currently hosting several producing mines and recent discoveries. Readily accessible by paved highway and gravel roads only 25 km from the town of Gabbs, Nevada. High voltage power is available approximately 30 km from the project and water rights have been secured.
Property Description	Property totals 1,457 hectares on patented and unpatented claims, subject to pre-existing NSR royalties.
Geology	Gold and silver occurring in low-sulphidation epithermal veins and in disseminations within sheeted and stockwork zones. Three gold areas have been outlined within a broad 3 km zone of anomalous gold values.
Historic Resources	342,000 ounces of gold contained in 17.5 million tonnes grading 0.61 grams per tonne in three zones, Paymaster, HRA and Penelas, as estimated by Canamex Gold. Endeavour has not verified this historic resource estimate and is not relying on it.
Potential	Discovery potential that is amendable to open pit mining with metallurgy using cyanide leach test results showing gold recoveries > 85% for 0.75” to 3.0” crush size with potential for run-of-mine leaching.
