EXCELLON OUTLINES HIGH-GRADE GOLD

OPPORTUNITIES AT KILGORE

Toronto, Ontario – March 10, 2022 – Excellon Resources Inc. (TSX:EXN; NYSE:EXN; FRA:E4X2) (“Excellon”

or the “Company”) is pleased to provide an update on the ongoing review of high-grade gold

opportunities from historical exploration of the Kilgore Project in Idaho.

Highlights

• Intensive review and rebuilding of Kilgore drillhole database demonstrates opportunities to

focus on high-grade gold potential with updated exploration techniques.

• Historic results were often reported in broad intervals, with discrete high-grade zones

encountered in diamond drilling including:

o 10.79 g/t Au over 6.20 metres in 16OKC-354;

o 9.53 g/t Au over 13.72 metres in 16OKC-353;

o 11.19 g/t Au over 7.62 metres in 10OKC-228;

o 8.65 g/t Au over 9.14 metres in 10OKC-220;

o 19.75 g/t Au over 4.27 metres in 95EKC-100;

• Drilling planned to define structures associated with high-grade gold emplacement through first

applications of modern downhole and oriented core surveying at Kilgore.

“The opportunity to define high-grade gold and make new high-grade discoveries was a key reason behind

our acquisition of the Kilgore Project in 2020,” stated Jorge Ortega, Vice President Exploration. “We are

applying a modern approach to historical data and plan to deploy more advanced surveying techniques in

the upcoming drill campaigns at Kilgore . Historic results demonstrate numerous high -grade intervals

throughout the deposit lithology, often associated with silicified zones, but with minimal associated

structural analysis. In this year’s program, we aim to de lineate the structures associated with high-grade

gold emplacement through drilling, geophysics and continued surface exploration to expand our

understanding and the potential of the deposit and project.”

High-Grade Interval Summary

The following table highlights high -grade intervals encountered in historic drilling and reported within

broader intervals of lower grade mineralization, also noting the drilling method used: diamond drilling

2022 Exploration Plans

The Kilgore deposit is a caldera -related epithermal gold deposit in Clark County, Idaho with a current

Indicated Resource of 44.6 million tonnes at 0.58 g/t Au for 825,000 ounces Au and an Inferred Resource

of 9.4 million tonnes at 0.45 g/t Au for 136,000 ounces Au.

The primary objectives of the 2022 exploration program at Kilgore are to (i) grow and increase the grade

of the existing mineral resource and (ii) define vertical to sub-vertical high-grade zones within the existing

mineral resource and to depth in the underlying Aspen formation. Detailed planning for the program is

ongoing, but is expected to include a combination of drilling, geophysics and surface work.

The proposed drilling program comprises two phases to define structures associated with high-grade gold

emplacement through the first applications of modern downhole survey and core orientation equipment

at Kilgore, including (i) the c onfirmation of historic high -grade intercepts within the Kilgore deposit and

(ii) exploration along trend and at depth focused on defined geophysical, geochemical and structural

features associated with gold mineralization.

Geophysical surveying is expected to include induced polarization and magnetotelluric surveys over the

Kilgore deposit and high priority targets to (i) better define structural features associated with gold

mineralization and (ii) define additional drill targets.

Surface work is expected to include mapping, sampling and soils over key areas, following up on Advanced

Spaceborne Thermal Emission and Refle ction Radiometer (ASTER) defined targets (see Company’s press

release dated December 21, 2020).

looking statements by the Company are not guarantees of future results or performance, and that actual results may differ materially from those

in forward looking statements as a result of various factors, including, but not limited to, variations in the nature, quality and qu antity of any

mineral deposits that may be located, significant downward variations in the market price of any minerals produced, t he Company's inability to

obtain any necessary permits, consents or authorizations required for its activities, to produce minerals from its properties successfully or
