DMX District Metals Corp

VANCOUVER, BC, March 31, 2021 /CNW/ - District Metals Corp. (TSXV: DMX) (FSE: DFPP); ("District" or the "Company") is pleased to announce the results of a ground gravity survey at the high grade polymetallic Tomtebo Property located in the Bergslagen Mining District in south-central Sweden.  This gravity survey was carried out in December 2020, and focused on the Tomtebo Mine Trend (Figure 1) that is centered on the historic Tomtebo Mine, and is delineated by numerous conductive and magnetic high anomalies identified from the July 2020 SkyTEM survey. 

Gravity Survey Highlights:

• Numerous gravity high anomalies have been identified at the historic Tomtebo Mine (Figure 2). These gravity high anomalies are within and well outside of the known mineralized domains, which provides confirmation and immense expansion potential.
  
  
• The gravity high anomalies at the historic Tomtebo Mine show an exploration target of over 72.0 Mt at a density of 3.45 g/cm³ from near surface down to a depth of 650 m. The gravity survey established a background density of 2.72 g/cm³ for the host felsic volcanic rocks, and the modeled gravity high anomalies could correspond with polymetallic and/or iron sulphide mineralization, or a mafic unit.
  
  
• A very significant blind gravity high anomaly has been identified 1.0 km northeast along trend from the historic Tomtebo Mine (Figure 2). This gravity high anomaly remains open to the northeast and at depth where an exploration target of 34.0 Mt at a density of 3.45 g/cm³ has been modeled at shallow depths (40 to 320 m).
  
  
• A significant gravity high anomaly has been identified 600 m southwest from the historic Tomtebo Mine (Figure 2). This gravity high anomaly is associated with historic iron sulphide occurrences, which are known to sometimes coalesce with polymetallic sulphide mineralization in the Bergslagen District. This exploration target remains open to the southwest and at depth where 28.7 Mt at a density of 3.50 g/cm³ has been modeled at shallow depths (near surface to 420 m).

The potential quantity and density of the exploration targets described above are conceptual in nature, and it is not possible to make assumptions on metal grades from a gravity survey.  There has been insufficient or no drilling to define a mineral resource or to determine if polymetallic sulphide mineralization is present, respectively.  It is uncertain if further drilling will result in these exploration targets being delineated as a mineral resource or resulting in the discovery of polymetallic sulphide mineralization.

Garrett Ainsworth, CEO of District, commented: "Our ground gravity survey covering the Tomtebo Mine Trend has worked extraordinarily well.  Interpretation of the gravity data has successfully confirmed proof of concept and identified compelling expansion potential at the historic Tomtebo Mine.  This survey has also revealed two high priority gravity targets with coincident magnetic and/or conductive anomalies located 0.6 to 1.0 km along trend from the Tomtebo Mine.  We are especially excited about the gravity high anomaly located one kilometer to the northeast of the Tomtebo Mine, which represents a potential grassroots discovery opportunity with a modeled tonnage that compares with the historic production tonnage from the historic Falun Mine."

The December 2020 ground gravity survey covered a 2 km by 3 km portion of the Tomtebo Mine Trend with 200 m line spacings and stations 50 m along the lines, which totaled approximately 400 gravity stations.  The large density differential between the surrounding host felsic volcanic rocks, and targeted polymetallic sulphide mineralization on the Tomtebo Mine Trend has generated an important data layer that in combination with magnetic, electromagnetic, and geochemical data has revealed priority drill targets.

Gravity Survey Background

Gravity surveys measure differences in the Earth's gravity field in milligals (mGal), which is sensitive to variations in rock density, and can be used to detect excess mass, which may indicate a potential massive sulphide deposit at depth, and to estimate the size of the excess mass. The sulphide minerals found in massive sulphide (VMS or SedEx) deposits have relatively high density values in marked contrast to lower density values measured in their volcanic and sedimentary host rocks. In its purest form, massive sulphide mineral density ranges from 4.0 to 7.5 g/cm³ while the felsic volcanic host rock ranges from 2.6 to 2.8 g/cm³.  Gravity high anomalies of 3.2 g/cm³ or greater are typical VMS and SedEx signatures that center over these types of deposits.

Volcanic Massive Sulphide (VMS) and SedEx deposits can often be identified by gravity survey data.  Metal content zonation within VMS systems in particular is typical from proximal feeder copper-gold zones being strongly conductive and weakly to strongly magnetic with the more distal SedEx silver-zinc-lead zones being weakly- to non-conductive and weakly to strongly magnetic, which can be greatly complemented by gravity data.  Where targets are blind, exploration drilling should be prioritized in areas that exhibit at least two coincident anomalies of conductivity, magnetics, or gravimetry.

About District Metals Corp.

District Metals Corp. is led by industry professionals with a track record of success in the mining industry. The Company's mandate is to seek out, explore, and develop prospective mineral properties through a disciplined science-based approach to create shareholder value and benefit other stakeholders.

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.
