The operation continued to realize improvements during the third quarter from the site organizational

changes implemented prior to the pandemic -mandated shut down. Improvements were recognized in

lower consumable costs, lower workforce costs, an increased in mine efficiency, improved mine extraction

by month and increased equipment reliability. At the process plant , a focus on feed blending, reagent

optimization and workforce shift schedule reorganization has resulted in plant operational stabilization

and increased metal recoveries with lower unit cost. Head grades were consistent with past performance,

with reduced silver feed grades the product of current mi ning areas and ordinary course variations.

Ongoing focus on business improvements and lower electricity prices from the newly activated power

contract at Platosa are expected to continue improving the operation’s economics.

The Company expects to file Q3 2020 financials on or about November 13, 2020.

COVID-19 Update

Excellon continues to implement measures to prevent COVID -19 among the workforce and local

communities and to monitor the effectiveness of these measures in mitigating any potential impact on

our business activities. Our actions have been successful to -date and t he pandemic has not had any

material impact on production or shipment of concentrate from any of the Company’s operations.

Update on Silver City Drilling Results

Drilling has continued as planned on the Company’s Silver City Project since early July. The Company has,

however, experienced significant delays in the return of assays from drilling on the project , which is also

being experienc ed across the industry. Core samples are sent from Frieberg to the external assaying

laboratory’s sample preparation facility in Poland for sample preparation. These samples are then flown

a central laboratory in British Columbia, Canada for processing. Th e logistics of this process, combined

with other COVID-19-related challenges and bull-market demand for assaying services , have resulted in

delays in receiving assays. The Company expects to release assay results from the ongoing program in due

course.
