District Receives Approval of Additional Viken Mineral License Applications in Central Sweden

Vancouver, British Columbia--(Newsfile Corp. - May 3, 2023) - District Metals Corp. (TSXV: DMX) (FSE: DFPP) ("District" or the "Company") is pleased to report that Bergslagen Metals AB (a 100% owned Swedish subsidiary of District) has received approval from the Bergsstaten (Mining Inspectorate) for the Viken nr 2 and 3 mineral license applications that covers the area to the south and north of the original Viken nr 1 mineral license application that encompasses 68% of the polymetallic Viken Deposit located in Jämtland County, central Sweden (Figure 1). The Viken Deposit is the largest undeveloped Alum Shale vanadium-uranium-molybdenum-nickel-copper-zinc deposit in Sweden, and amongst the largest deposits by total historic mineral resources of vanadium and uranium in the world.

Highlights:

• The approved Viken nr 2 and 3 mineral license applications have increased the area of the Viken Property from 2,302 hectares (ha) to 9,367 ha.

• Expansion of the Viken Propery to the south (Viken nr 2) and north (Viken nr 3), will allow the Company to target mineralized Alum Shale that has been tectonically thickened from 20 to 30 m by thrusting and folding up to 180 m.

• Historical drill holes completed within the area of the Viken nr 2 and 3 mineral license applications returned grades and widths of mineralization that are consistent with drill results from within the Viken Deposit (Tables 1 to 3).

• There is currently a moratorium on uranium mining and exploration that was imposed in 2018. The Swedish Government has a positive stance on re-evaluating and lifting the moratorium.

Garrett Ainsworth, CEO of District, commented: "The Viken Property now comprises three large mineral licenses (Viken nr 1 to 3) that are in good standing for the next three years, and cover the majority of the polymetallic Viken Deposit and its likely extensions to the north and south as evidenced by historic drill hole results."

Table 1: Historical Drill Results from Viken nr 2

Notes:

• Continental Precious Minerals Inc. released these drill results in 2007.
• True widths of the reported mineralized intervals have not been determined, but are expected to be near 100% given the flat lying nature of the Alum Shale host unit that is drilled by vertical holes.
• V ppm has been converted to V2O5 ppm by multiplying the V ppm value by 1.7826.
• U ppm has been converted to U3O8 ppm by multiplying the U ppm value by 1.17924.
• These drill results are historical in nature. District has not undertaken any independent investigation of the sampling nor has it independently analyzed the results of the historical exploration work in order to verify the results. District considers these historical drill results relevant as the Company will use this data as a guide to plan future exploration programs. The Company also considers the data to be reliable for these purposes, however, the Company's future exploration work will include verification of the data through drilling.

The Polymetallic Viken Deposit

The Viken Deposit is situated in the province of Jämtland, approximately 570 km northwest of Stockholm, Sweden. Infrastructure is well developed in the area with daily air service, as well as rail and truck freight services. Electrical power and modern communications are also readily available in the area.

The Geological Survey of Sweden (SGU) carried out work on the Alum Shales from 1977 to 1978 and drilled approximately 19 holes within and in the vicinity of the Viken Deposit. In 2005, Continental Precious Minerals Inc. (CPM) purchased mineral licenses that covered prospective Alum Shales where CPM drilled 26,293 m in 133 holes from 2006 to 2008 to delineate the Viken Deposit.

CPM retained P&E Mining Consultants Inc. to carry out a Resource Estimate and PEA in 2010 that resulted in the following historical estimate:

Notes:

• The mineral resource estimates contained in this table are considered to be "historical estimates" under National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"). A Qualified Person has not done sufficient work to classify the historical estimate as a current mineral resource, and the Company is not treating these historical estimates as current Mineral Resources. The Company would need to conduct an exploration program, including twinning of historical drill holes in order to verify the Viken Deposit historical estimate as a current mineral resource.
• Weighting of composite samples by linear Ordinary Kriging was used for the estimation of block grades. Kriging parameters were based on the grade-element variography derived from the mineralized shale domain. A block discretization level of 5 x 5 x 2 was used during kriging. The mineralized shale domain was treated as a hard boundary, and data used during estimation were limited to composite samples located within the mineralized shale domain wireframe. Only blocks wholly or partially within the mineralized shale domain were estimated. The mineralized shale domain was treated as a hard boundary, and data used during estimation.
• During the first pass, four samples from each of three drill holes within 110m of the block centroid were required. All block grades estimated during the first pass were classified as Indicated.
• During the second pass, blocks not populated during the first pass were estimated. A minimum of three and a maximum of six samples from one or more drillholes within 330 m of the block centroid were required. All block grades estimated during the second pass were classified as Inferred.
• An internal break-even cut-off grade of US $7.50/tonne was used in reporting this historical estimate.

In 2012, a bio-heap leach scenario was evaluated, and P&E Mining Consultants were retained again to conduct an Updated Technical Report, Resource Estimate and Preliminary Economic Assessment on the Viken Deposit with the following historical estimate:

A Qualified Person has not done sufficient work to classify the historical estimate as a current mineral resource, and the Company is not treating these historical estimates as current Mineral Resources. The Company would need to conduct an exploration program, including twinning of historical drill holes in order to verify the Viken Deposit historical estimate as a current mineral resource.
• Block grades were estimated using Ordinary Kriging of capped composite samples. Only blocks wholly or partially within the mineralized shale domain were estimated, and between six and fifteen samples from two or more drill holes within 660 m of the block centroid were used for estimation. A small area in the Southern portion of the deposit with an average drillhole spacing of approximately 120 m has been classified as Indicated.
• An internal break-even cut-off grade of US $11.00/tonne was used in reporting this historical estimate.

The Viken Deposit is a polymetallic shale resource contained within the Cambrian Viken Shale which regionally is referred to as the Alum Shale. The Alum Shale is enriched in metals such as vanadium, uranium, nickel, copper, zinc, and molybdenum. It occurs over a significant area in Sweden and is locally valued as a bituminous shale with recoverable hydrocarbons. The Alum Shale is regionally extensive in Sweden.

The stratigraphy across the Viken Mineral License application consists of upper Middle and Upper Cambrian age Alum Shale occurring as both in situ and fault detached blocks, with the latter having greater potential for economic mineralization due to imbrication of mineralized blocks. The Alum Shale is mostly exposed at surface and is underlain by Proterozoic granites and gneisses thrust Eastward over Archean granitic basement rocks. The thickness of the Alum Shale host rock has been tectonically thickened from 20 to 30 m by thrusting and folding during the Silurian to approximately 180 m.

Mineralization of potential economic significance is hosted in Middle and Upper Cambrian Alum Shale, with the Upper Cambrian age strata more enriched in vanadium and uranium than the Middle Cambrian³. Vanadium occurs within the lattice of a mica mineral named roscoelite. Uranium values are predominantly associated with sub-micron-scale uraninite crystals. Nickel, molybdenum, copper and zinc are present as sulphides.
