District Intersects 9.1 m at 6.1% ZnEq on the Gruvberget Property

Vancouver, B.C. September 21, 2022

September 21, 2022 – District Metals Corp. (TSX-V: DMX) (FRA: DFPP) ("District" or the

“Company”) is pleased to report assay results for five drill holes (GRU22-001 to -005) from the

Spring-Summer 2022 drill program at the polymetallic Gruvberget Property located in the

Bergslagen Mining District in south-central Sweden.

A total of 1,144 m in five drill holes was completed at the Gruvberget North zone from mid-

May to early-July 2022. All of the drill holes were 30 to 60 m step outs below historical drill

intercepts where four out of five holes intersected polymetallic sulphide mineralization that

remains open at depth and partially along strike.

Highlights:

• GRU22-002 intersected 9.1 m at 6.1% ZnEq1 (130.0 to 139.1 m).

o Including 3.3 m at 13.0% ZnEq1 (134.0 to 137.3 m).

• GRU22-003 intersected 9.2 m at 5.9% ZnEq1 (127.0 to 136.2 m).

o Including 2.7 m at 9.2% ZnEq1 (133.5 to 136.2 m).

A long section is shown in Figure 1, and drill assay results are shown in Table 1. Drill hole

summaries are reported here.

Garrett Ainsworth, CEO of District, commented: “Our first pass drill program at the Gruvberget

Property has been a great success. Drilling at the Gruvberget North zone has returned significant

polymetallic assays over appreciable widths with continuity that remain open from a shallow

vertical depth of approximately 160 m. The vertical extent of some polymetallic depo sits in the

Bergslagen District can be quite significant such as Boliden’s Garpenberg Mine and Lundin

Mining’s Zinkgruvan Mine where mineral resources extend to depths of 1,600 m, which makes

the window of opportunity at Gruvberget very large. The Gruvberget North zone warrants a much

larger drill program to better assess the size and scale of the mineralized system we have on hand.”

Notes:

• All intervals are core lengths, and true thicknesses are yet to be determined. Mineral resource modeling is required before true thicknesses can be estimated.

• Cut-off grade of 1.2% ZnEq was utilized, which may include up to 2.0 m of internal dilution. Underground mining cut -off at the nearby Garpenberg Mine was

US$29/tonne in 2021.

• Metal prices used in USD for the ZnEq cut-off calculations were based on Ag $15.00/oz, Au $1650/oz, Cu $2.15/lb, Zn $0.85/lb, and Pb $0.75/lb.

• ZnEq = Zn% + (Ag g/t × 0.0257) + (Au g/t x 2.831) + (Cu% × 2.529) + (Pb% × 0.882)

• The use of ZnEq is to calculate cut-off grades for exploration purposes, and no adjustments were made for metal recovery.

The drill core reported in this news release w as logged and prepared at the District Metals AB

core facility in Säter, Sweden before submittal to ALS Geochemistry in Malå, Sweden where the

drill core is cut, bagged, and prepared for analysis. Sample pulps were sent to ALS Geochemistry

in Ireland (an accredited mineral analysis laboratory) for analysis. Samples were analyzed using

a m ulti-element ultra-trace method combining a four -acid digestion with ICP -MS analytical

package (“ME-MS61”). Over limit sample values were re-assayed for: (1) values of copper >1%;

(2) values of zinc >1%; (3) values of lead >1%; and (4) values of silver >100 g/t using the high-

grade material ICP-AES analytical package (“ME-OG62”). Additional over limit sample values

were re-assayed for: (1) values of zinc >30%; (2) values of lead >20% using the high precision

analysis of b ase metal ores AAS analytical package (“Zn, Pb -AAORE”). Gold, platinum, and

palladium were analyzed using the 30 g lead fire assay with ICP -AES finish analytical package

(“PGM-ICP23”). Certified standards , blanks, and duplicates were inserted into the sample

shipment to ensure integrity of the assay process. Selected samples were chosen for duplicate

assay from the coarse reject and pulps of the original sample. No QA/QC issues were noted with

the results reported.

Some of the data disclosed in this news release is related to historical drilling results. District has

not undertaken any independent investigation of the sampling nor has it independently a nalyzed

the results of the historical exploration work in order to verify the results. District considers these

historical drill results relevant as the Company is using this data as a guide to plan exploration

programs. The Company's current and future ex ploration work include s verification of the

historical data through drilling.

Mr. Ainsworth has not verified any of the information regarding any of the properties or projects

referred to herein other than the Gruvberget Property. M ineralization on any ot her properties

referred to herein is not necessarily indicative of mineralization on the Gruvberget Property.

The advanced exploration stage Tomtebo Property is located in the Bergslagen Mining District

of south- central Sweden is the Company’s main focus. Tomtebo comprises 5,144 ha and is

situated between the historic Falun Mine and Boliden’s Garpenberg Mine that are located 25 km

to the northwest and southeast, respectively. Two historic polymetallic mines and numerous

polymetallic showings are located on the Tomtebo Property along an approximate 17 km trend

that exhibits similar geology, structure, alteration and VMS/SedEx style mineralization as other

significant mines within the district. Mineralization that is open at depth and along strike at the

historic mines on the Tomtebo Property has not been followed up on, and modern systematic

exploration has never been conducted on the Property.

For further information on the Tomtebo Property, please see the technical report entitled “NI 43-

101 Update Technical Report on the Tomtebo Project, Bergslagen Region of Sweden” dated

effective October 15, 2020 and amended and restated on February 26, 2021, which is available
