Norden Crown Intersects High Grade and Significant Widths of Broken Hill Type Mineralization in All Three Holes Drilled at Its Fredriksson Gruva Prospect in Sweden

Norden Crown Metals Corp. (“Norden Crown” or the “Company“) (TSXV:NOCR, OTC:NOCRF, Frankfurt: 03E) is pleased to announce an exceptional discovery at its 100% owned Fredriksson Gruva prospect (“Fredriksson Gruva”) demonstrated by significant results from the first three holes drilled below historical mine workings.  The discovery holes intersected significant mineralized widths ranging from 8.15 to 13.60 metres of precious and base metal, massive and semi-massive sulphide mineralization, within a geological setting unique to mineralization belonging to the Broken Hill Type (“BHT“) clan of silver rich zinc-lead ore deposits.

“We are delighted to present to our shareholders robust silver-zinc-lead intersections which are part of a bona fide Broken Hill Type mineralizing system at Fredriksson Gruva; the widths and grades intersected beneath the historical mine workings suggest that the Gumsberg Project has exceptional growth potential”.  Stated Patricio Varas, Chairman and CEO of Norden Crown.  “Massive sulphide deposits are special because it is possible to delineate large tonnages from comparatively small drill footprints due to the high density of the mineralization.  To put these results into perspective, Norden Crown’s GUM-20-09 intercept is comparable in width to the height of a three storey building.”

The results of the drilling program at Fredriksson Gruva are further described in Tables 1, 2 and 3 below.

Drilling Program at Fredriksson Gruva

The three discovery drill holes (totaling 569 metres) completed at Fredriksson Gruva were part of an eleven hole 2,365.6 metre diamond drill program completed at the Company’s 100% owned Gumsberg Project, located in the Bergslagen Mining Region of southern Sweden.  The objective of the drill program was to demonstrate that mineralization continues beneath the historical mine workings, which extend to 91 metres below surface.  The program was also designed to confirm historical silver-zinc-lead grades, thicknesses, and to test the continuity of this mineralization.  Holes GUM-20-09 and GUM-20-10 are positioned 30 metres down plunge of the historical underground workings and are spaced 40 metres apart.  Hole GUM-20-11 is 30 metres below GUM-20-10 (60 metres below the historical workings) (see Figure 1).

An important aspect of the mineralization is that the massive to semi-massive sulphide intervals are developed within a broader sequence of highly magnetic iron and manganese-rich chemical sediments. This distinctive and thick sequence of chemical sedimentary rocks will provide an important marker horizon that will be used to track the mineralization along strike and at depth.  Future diamond drilling at Fredriksson Gruva will continue testing the continuity of BHT style massive sulphide mineralization and associated iron formation below the historical mine workings where ongoing 3D geological modeling demonstrates that silver- zinc-lead mineralization extends to at least 290 metres in depth.

A geological review of this newly recognized mineralization indicates that the mineralized formation is folded, forming a moderate to steeply eastward-plunging open anticline.  BHT mineralization at Fredriksson Gruva is associated with an extensive regional-scale magnetite-rich iron formation(s) and corresponding magnetic anomaly which Norden Crown intends to further delineate in the subsurface using detailed UAV magnetic geophysical surveys.  Regional magnetic geophysical data sourced from the Geological Survey of Sweden suggests that the prospective magnetic anomaly (and coincident magnetite-bearing iron formation) extends over 21 kilometres across the Gumsberg West Licence (southwest of Fredriksson Gruva) greatly enhancing the exploration potential for further BHT discoveries (see Figure 2).

The nearest occurrence of BHT mineralization is located immediately south of the Gumbsberg claims at Stollgruvan, where the Gammsberg mine (6.7M Tonnes¹) has been described as a BHT deposit hosted in banded iron formations ^2,3,4.

About Broken Hill Type Deposits

BHT Ag-Zn-Pb deposits constitute some of the largest and highest-grade ore deposits in the world² (see Table 4). The namesake deposit, Broken Hill, is located in western New South Wales, Australia, and represents the largest accumulation of Pb, Zn, and Ag on Earth².   BHT deposits constitute a distinctive type of stratiform, sediment hosted lead-zinc mineral deposits.  BHT deposits are characterized and distinguished from other silver-zinc-lead deposits by the chemistry of the sediment that host them and that they are usually associated spatially and temporally with volcanism.

Characteristic features of these types of deposits include:

• High grade Ag + Zn + Pb mineralized ores
• Metamorphic grades ranging to amphibolite-granulite facies
• Paleoproterozoic oxidized clastic metasedimentary host rocks in the absence of metamorphosed carbonates/calcsilicate horizons
• Spatially associated with bimodal (felsic and mafic) intrusive and volcanic rocks, and stratabound gahnite- and garnet-bearing rocks and iron formations
• Stacked orebodies with characteristic Pb:Zn:Ag ratios and skarn-like (generally pyroxenoid dominated) Fe-Mn-Ca-F gangue assemblages
• Sulfur-poor assemblages
• A spatial relationship to continental rifts

Significantly, the intimate association with magnetite iron formations is considered an important guide for Norden Crown to follow and explore for continuous mineralized BHT deposits along the +21 kilometre belt of prospective iron formation.  In addition, the association of manganiferous garnets (spessartine), the presence of stratabound gahnite in the metamorphosed sedimentary rocks, and anomalous base metals in these deposit types provide an excellent first pass screening that will be useful for evaluating these prospective iron formations for their potential to host BHT deposits.

Quality Control, Quality Assurance and Core Handling Protocols

Drill core is logged and prepped for sampling before submittal to ALS in Malå, Sweden where it is cut, bagged and prepped for analysis. Accredited control samples (blanks and accredited standards) are inserted into the sample intervals regularly. Samples are dried (if necessary), weighed, crushed (70% < 2mm), and riffle split into two fractions. One is retained (coarse reject) and the other is pulverized to 85% < 75µm. Pulps are analyzed by ultra-trace ICP-MS (ME-MS41) and ICP-AES Au (Au-ICP22). Over detection limit samples are reanalyzed using ore grade ICP-AES by aqua regia (ME-OG62) or by AAS in the case of high-grade zinc (ZnAAORE).
