EXCELLON UPDATES EVOLUCION
MINERAL RESOURCE ESTIMATE
Toronto, Ontario – September 17, 2020 – Excellon Resources Inc. (TSX:EXN, EXN.WT; OTC:EXLLD and
FRA:E4X2) ("Excellon" or the “Company") is pleased to provide an updated Mineral Resource Estimate
(“MRE”) for the Calvario and Lechuzas Zones on the Evolución Project in Zacatecas, Mexico as at
July 31, 2020.
2020 Evolución MRE Highlights
Updated MRE incorporates 17,120 metres of additional surface drilling completed in the
resource area from June 2018 to December 31, 2019
Indicated resource of 6,407,000 tonnes at 170 g/t silver equivalent (“AgEq”) representing
35,091,000 AgEq ounces
Inferred resource of 14,960,000 tonnes at 135 g/t AgEq representing 64,813,000 AgEq ounces
Expansion drilling being planned to test the strike extension of the mineralized zones and follow
up on parallel structures, where grab samples taken during detailed mapping in 2020 returned
values of up to 2.30 g/t Au, 203 g/t Ag and 10.4% Pb
“We discovered the Lechuzas zone adjacent to our Miguel Auza mill in late 2018 and identified a
sizeable mineral resource that, when combined with the historic Calvario Vein, is similar to other
deposits currently producing in the region,” stated Ben Pullinger, SVP Geology. “This MRE represents a
sizeable addition to Excellon’s overall metal inventory and a foundation to further advance the project,
as both Lechuzas and Calvario are open for extension along strike and at depth.”
Resource Summary for Evolución Project
The MRE will be included in an updated technical report prepared by SRK Consulting (Canada) Inc.
(“SRK”) under National Instrument 43‐101 ("NI 43‐101"), which will be published on SEDAR
(www.sedar.com) in the coming weeks.

Notes:
1. Mineral Resources are estimated pursuant to NI 43‐101 with an effective date of August 31, 2020.
2. Mineral Resources are reported at a cut‐off grade of 90 g/t AgEq. Cut‐off grades are based on a silver price of US$17 per troy
ounce and a silver recovery of 76%; a gold price of US$1,550 per troy ounce and recovery of 20%; a lead price of US$0.90 per
‐ 2 ‐
pound and recovery of 90%; and a zinc price of US$1.15 per pound and recovery of 88%.
3. Mineral Resources that are not Mineral Reserves do not necessarily demonstrate economic viability. All figures have been rounded
to reflect the relative accuracy of the estimates. Composites have been capped where appropriate.
4. The mineral resources were estimated in conformity with the widely accepted CIM Estimation of Mineral Resource and Mineral
Reserves Best Practices Guidelines (November 2019) and are reported in accordance with the Canadian Securities Administrators’
National Instrument 43‐101.
5. The construction of the Mineral Resource model was a collaborative effort between Excellon and SRK personnel. Dr. Aleksandr
Mitrofanov, P.Geo. (APGO#2824) is responsible for resource wireframing, geostatistical analysis, grade estimation and
classification with senior review provided by Mr. Glen Cole, PGeo (APGO#1416).
The Lechuzas Zone was modelled in conjunction with a remodeling of the historical Calvario vein system.
The evaluation of mineral resources for these zones on the Evolución Project involved the following:
1. Validation and verification of the Excellon drill hole and analytical database and QA/QC
performance;
2. Construction of explicit wireframe domains for mineralization using geological indices and structural
trends;
3. Definition of resource domains;
4. Data conditioning (compositing and capping) for geostatistical analysis and variography and
determination of specific gravity;
5. Definition and interpolation of a 3D block model;
6. Validation, classification and tabulation;
7. Assessment of “reasonable prospects for eventual economic extraction” and selection of cut‐off
grade and grade sensitivity analysis; and
8. Preparation of the MRE.
This model incorporates data from 239 drill holes (68,361 metres) completed by previous operators at
Calvario and 34 diamond holes (14,509 metres) completed by Excellon from 2018 to 2020 on the Lechuzas
zone. Additional work completed and integrated into the model included structural studies completed in
2018, oriented core data, petrographic studies, re‐logging and re‐assaying of historical mineralized
intersections and a re‐interpretation of the geology and mineralization of the studied area.
Mineral resource modeling of the Evolución Project incorporates lithological and structural geology
modeling and grade interpolation. SRK used the available data to create a geological model delimiting
the different mineralized domains in Leapfrog Geo™. The model comprises a total of twelve high‐grade
veins (eight at Calvario and four at Lechuzas), and three low‐grade haloes for each zone.
The high‐grade vein domains were generated using a combination of geological descriptions, where they
were available, and AgEq values. The high‐grade domains were constrained based on economic
composites greater than 10 g/t AgEq threshold and a maximum waste inclusion of 1 metre. Low‐grade
domains were modelled based on economic composites of 2 g/t AgEq threshold and a maximum of 3
metres waste inclusion, and further constrained using interval selections based on structural trends. The
AgEq calculations are based on a silver price of US$17.00 per troy ounce (t oz) and a silver recovery of 76%;
a gold price of US$1,550 per t oz and a gold recovery of 20%; a lead price of US$0.90 per lb and a lead
recovery of 90%; and a zinc price of US$1.15 per lb and a zinc recovery of 88%. Recovery values are based
upon the total overall recovery values documented by Roscoe Postle Associates Inc. (2008), determined
by the metallurgical testwork completed by Silver Eagle Mines Inc.
Approximately 12% of the tonnage within the MRE (26% of the indicated tonnage and 6% of the inferred
tonnage) is located within the La Antigua concession (part of the Evolución Project), which is the subject
of litigation between a subsidiary of Excellon and a plaintiff. The initial decision in respect of this litigation
does not affect Excellon’s contractual rights to this concession.

The MRE was prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum’s
(CIM) ‘Mineral Resources and Mineral Reserves Best Practices’ guidelines (November 2019) and is
classified per the CIM ‘Definition Standards for Mineral Resources and Mineral Reserves’ (May 2014).
The Evolución property covers 45,000 hectares (450 km2) and 35 kilometres of strike in one of the world’s
premier silver mining districts, known as the Fresnillo trend. The Lechuzas and Calvario Zones are hosted
within the Caracol Formation, which hosts the most significant deposits on the Fresnillo trend. Precious
and base metal mineralization is associated with structures featuring carbonate and quartz veining that
crosscut the host rocks. Pyrite, sphalerite, and galena are the most commonly observed sulphide
minerals. The property includes a conventional grinding and flotation mineral processing facility, through
which the Company currently processes ore from its Platosa Mine. The mineral processing facility
currently has nameplate capacity of approximately 800 tonnes per day (“tpd”), with a 650 tpd ball mill in
operation and a second, 150 tpd ball mill on standby, with opportunities available for further expansion.
Ongoing Exploration at Evolución
Detailed mapping and surface sampling are underway on the Evolución Project. Numerous samples with
anomalous geochemical signatures have been identified in the target area; these are thought to be the
surface expressions of epithermal alteration and associated mineralization. The program will be used to
aid in structural modeling and targeting for future drilling.
Qualified Person
Mr. Ben Pullinger, P.Geo., Senior Vice President Geology, has acted as the Qualified Person, as defined in
NI 43‐101, with respect to the disclosure of the scientific and technical information contained in this press
release.
Update on Trading Symbols on the OTC Pink and Frankfurt Exchanges
Further to the Company’s press release on September 10, 2020 announcing the effective date of the
consolidation of the Company’s common shares on a one‐for‐five basis, the following adjustments were
made to trading symbols on the OTC Pink and Frankfurt Exchanges:
On the OTC Pink, Excellon’s symbol was changed from “EXLLF” to “EXLLD”. The new symbol will
