NORDEN CROWN METALS CORPORATION Norden Crown intersected previously untested IOCG style copper mineralization, which subsequently became the focus of the drilling program. Norden Crown is excited to share the assay results in the coming months.
Norden Crown simultaneously completed a 6,800 - sample soil survey, a 3-week geological and structural mapping campaign and borehole electromagnetic geophysical surveys during the exploration program.
Previous drilling by Norden Crown (see News Release dated March 20, 2019) at Burfjord returned compelling results including an intercept of 32 metres averaging 0.56% copper and 0.26 g/t gold (including 3.46 metres of 4.31% copper and 2.22 g/t gold) below a cluster of historical mine workings at the Gamlegruva target area1,2. Previous drilling confirmed presence of high grade carbonate-jasper-magnetite-chalcopyrite-bornite veins cutting through pervasively magnetite-albite altered gabbro with broad mineralized zones within carbonate-magnetite-chalcopyrite stockworks and breccias enveloping these high-grade veins, under the historical workings. Historical drilling on the Project (Cedarsgruven) was reported to have returned 7.0 metres averaging 3.6% copper3.
Norden Crown completed 3,499.40 metres of diamond drilling in 18 drill holes designed to test a combination of geological, geochemical, and geophysical targets identified from 2020 and 2021 field programs (Figure 1). Drilling commenced on
Most of the drilling this year has focused on the Eastern Limb of the Burfjord anticline (Gamlegruva and A-Gruva target areas) which constitutes a ~5-kilometre-long trend of discontinuously outcropping copper occurrences and historical mine adits that contain copper sulphide mineralization (chalcopyrite and bornite) associated with magnetite-hematite-jasper-bornite-chalcopyrite veins and carbonate-magnetite-chalcopyrite vein stockworks and breccias, hosted in sodic and potassic altered pillow basalts and gabbros (Figure 1).
Holes at Gamlegruva tested a gabbro unit associated with a magnetic feature (Figure 2) and surface copper bearing vein stockworks. Hole BUR-22-012 intersected several significant magnetite-jasper-hematite-bornite-carbonate-chalcopyrite veins and adjacent zones of carbonate-magnetite-hematite-quartz-chalcopyrite vein stockwork and breccias.
Follow up drill holes (BUR-22-013 and BUR-22-017) were completed to test the down dip and along strike (northward step outs up to 130 metres) continuity of mineralization intersected in BUR-22-12. These drillholes confirmed the continuity of significant IOGC style copper mineralization within a pervasively magnetite-albite altered gabbro unit.
The magnetic feature associated with newly intersected IOCG mineralization extends southward and continues under the Caledonian nappe complex and northwards along the host gabbro unit (Figures 1 and 2). Additional drilling is required to test this target at depth.
The first batch of samples from the program is currently being assayed with results expected in the coming weeks. The final batch of samples is now at the assay laboratory and Norden Crown looks forward to sharing the results of this drill program in the coming months. Planning is already underway to continue building on the newly discovered copper mineralization at Gamlegruva.
A total of 3 weeks of geological mapping has been completed at Burfjord in 2022. Mapping focused on tracing the surface expression of the copper mineralized vein trend intersected in BUR-22-012 and follow up drillholes (Figure 1).
Several discontinuously outcropping magnetite-hematite-jasper-chalcopyrite-bornite and carbonate-magnetite-chalcopyrite-quartz veins (up to 1.5m wide) with halos of ankerite-jasper-magnetite-chalcopyrite stockwork were identified along a trend which
extends the zone along strike for at least 450 meters north of the newly identified mineralized trend at Gamlegruva. This significantly increases Norden's confidence in the target which will be a focus for drilling in Q1 2023.
Furthermore, mapping across the eastern limb has been completed with the aim of collecting structural data on copper-bearing veins. The information compiled from the geological and structural mapping program is being fed into the GIS database in order to improve the current geological modelling and technical understanding of the target areas and will aid with the planning of exploration programs and drilling envisioned for the 2023 winter.
Geophysical surveys were conducted between
Preliminary results from the borehole electromagnetics have identified two significant off-hole conductive features at the Gamlegruva target area. These results are being evaluated to place these features in a geological context based on previous mapping and drillhole data.
Optical televiewer data has been collected and processed and is currently being interpreted. These data will be used to establish the orientation of copper mineralized veins and to further constrain the 3-dimensional geometry of the target areas.
Petrophysical survey data is being processed which will be used to refine magnetic models at Burfjord to highlight regions of increased mineralized fluid flow.
A total of 6,800 soil samples were collected over the Burfjord licences this summer. Grids were planned with 20-meter sample spacing and line spacing of 100m between east-west lines.
An orientation soil survey consisting of 2,400 samples over an area of 5.1 sq-km was completed between
Samples are currently being analysed and preliminary results will be used to guide the planning of follow up drilling. Anomalies will be evaluated and ranked in advance of follow-up drill targeting at the various target zones including Cedarsgruven, where 2021 drilling returned 12 metres averaging 1.27% Cu in hole BUR-21-011 (see News Release dated
The Project, located in the Kåfjord Copper Belt near Alta,
Burfjord is comprised of six exploration licenses totalling 5,500 hectares. Within the license area, during the nineteenth century, copper mineralization was mined from over 30 historical mines and prospects developed along the flanks of a prominent 4 x 6-kilometre anticlinal fold consisting of interbedded sedimentary and volcanic rocks. Many of the rocks in the anticline are intensely hydrothermally altered and contain sulphide mineralization.
The high-grade copper gold veins at Burfjord, that were historically mined at cut- off grades of 3-5% copper, are surrounded by envelopes of stockwork veins or disseminations of copper mineralization extending tens to hundreds of metres laterally into the host rocks. Norden Crown believes this mineralization has economic potential and represents an attractive bulk tonnage exploration drilling target. Copper bearing veins in the area are dominated by ferroan carbonate, sodium-rich minerals, and iron-oxide minerals (magnetite and hematite), but also contain the economically important minerals chalcopyrite, bornite and chalcocite in addition to cobalt-rich pyrite as generally coarse-grained (often 0.5 centimetre to multi-centimetre scale) disseminations in the veins.
