Norden Crown Metals Corp. ( " Norden Crown " or the " Company ") (TSXV: NOCR) (OTC: NOCRD) ( Frankfurt ; 03E) is pleased to announce the commencement of surface exploration at its 100% owned Gumsberg Project, located in the precious and base metal rich Bergslagen Province of southern Sweden (Figure 2). The objective of the surface exploration is to enhance existing exploration drilling targets through mapping, sampling, and airborne geophysics at the Fredriksson Gruva target (" Fredriksson Gruva "), a Broken Hill Type (BHT) silver-zinc-lead prospect, where recent drilling delineated up to 13.60 metres of 6.05% zinc, 1.39% lead and 43.20 gt silver confirming the prospect's potential for expansion. (see Table 1, Figure 1 and Norden Crown news release dated March 1 2021)
"Surface exploration work at Gumsberg will focus on expanding the current footprint of silver rich based metal mineralization at Fredriksson Gruva". Stated Patricio Varas , President and CEO of Norden Crown . "Broken Hill Type deposits have the potential to yield large tonnages from comparatively small drill footprints due to the high density of the mineralization, so we are conducting detailed geological mapping and tightly spaced airborne magnetic geophysics to delineate mineralization in advance of additional diamond drilling."
Table 1. Results from drilling at Fredriksson Gruva
| Drill | Prospect | From | To | Length | Zinc | Lead | Silver |
| Hole | Name | (metres) | (metres) | (metres) | (%) | (%) | (g/t) |
| GUM-20-09 | Fredriksson Gruva | 123.70 | 134.05 | 10.35 | 5.24 | 1.84 | 43.86 |
| GUM-20-10 | Fredriksson Gruva | 134.90 | 148.50 | 13.60 | 6.05 | 1.39 | 43.20 |
| GUM-20-11 | Fredriksson Gruva | 151.85 | 160.00 | 8.15 | 3.83 | 0.503 | 18.13 |
*Insufficient drilling has been completed to definitively determine true thickness; true thickness is estimated to be between 90-95% for holes GUM-20-09 to GUM-20-11 based on angle to core axis and 3D interpretation.
2021 Surface Exploration Program
The 2021 Gumsberg surface exploration program will focus mainly on expanding the footprint of BHT mineralization intercepted below the Fredriksson Gruva historical mine workings in March 2021 (see Norden Crown news release dated March 1, 2021). Geological mapping, sampling, and prospecting will be conducted in the vicinity of Fredriksson Gruva in advance of a high resolution airborn e (UAV) magnetic geophysical survey which will be used to trace mineralization in the subsurface. Precious metal enriched based metal mineralization at Fredriksson Gruva is spatially associated with a broader horizon of highly magnetic iron and manganese-rich chemical sedimentary rocks. This thick magnetic sequence is geologically and geophysically distinctive and can be modeled in three dimensions using detailed magnetic data. The surface and subsurface mapping efforts will increase the confidence in the existing drill targets at Frederickson Gruva and allow the Company to gain insight into the prospects' size potential .
Mineralization at Fredriksson Gruva is folded, forming a moderate to steeply eastward-plunging open anticline. BHT mineralization at Fredriksson Gruva is associated with extensive regional-scale magnetite-rich iron formation(s) with corresponding regional scale magnetic anomalies which Norden Crown also intends to further delineate in the subsurface using airborne 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 additional BHT discoveries (see Figure 2).
About Broken Hill Type Deposits
BHT deposits constitute some of the largest and highest-grade ore deposits in the world 1 . The namesake deposit, Broken Hill, is in Western Australia and represents the largest known accumulation of Ag, Zn, and Pb on Earth 1 . BHT deposits constitute a distinctive type of stratiform, sediment hosted silver-zinc-lead mineral deposits. They 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 that range from upper greenschist to 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 Ag:Zn:Pb ratios and skarn-like (generally pyroxenoid dominated) Fe-Mn-Ca-F gangue assemblages
- Sulfur-poor assemblages
A spatial relationship with continental rifts and an association with magnetite iron formations is considered important to the genesis of BHT deposits and can be used to vector toward additional BHT mineralization along the +21 kilometre belt of prospective host rocks (see Figure 2). In addition, the association of manganiferous garnets (spessartine) and anomalous base metals in these deposit types will be used to help to evaluate the numerous prospective iron formations in the belt for their potential to host BHT deposits.
