The 2022 exploration drilling program at Burfjord is focused on several copper targets that are surrounded by historical adits, pits, trenches, and workings within the extensively iron-carbonate altered Burfjord Anticline (Figure 1).
These targets have been identified and prioritized based on lithological and structural mapping, rock and soil geochemistry, airborne magnetic geophysics and ground based electromagnetic geophysics. High priority target areas for this summer are presented below.
The geology of West Limb is dominated by a 3,000 meter by 400-metre albite-iron carbonate-magnetite alteration assemblage in clastic sedimentary rocks (L-Unit; Figure 1) that is locally brecciated and contains disseminated copper sulphides (chalcopyrite) and chalcopyrite bearing quartz-carbonate veins. Extensive historical pits, trenches and adits are present along a strike length of at least 800m along the trend of several shale horizons adjacent to the L-unit which represent attractive traps for copper-gold mineralized fluids (Figure 1).
Field exploration programs in 2020 and 2021 delineated an intense magnetic anomaly, several conductive ground conductors (TEM) (Figure 2), rock samples with elevated copper, a copper soil anomaly, and several faults thought to be possible fluid conduits.
The drill program will test both strike and depth continuity of mineralization along the western limb of the Burfjord anticline (Figure 2).
The East Limb of the Burfjord anticline constitutes a ~5 kilometre-long trend of discontinuously outcropping copper occurrences and historical mine adits that contain disseminated copper sulphide mineralization (chalcopyrite and sporadic bornite) associated with hematite-jasper breccia and carbonate vein stockworks hosted in potassic altered pillow basalts and albitized black shales.
The objective of the current drill program is to follow up on 2021-hole BUR-21-005 which returned 1.35m averaging 8.67% Cu and 0.69 g/t Au (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 fold (anticline) 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. The sodium-rich styles of alteration and mineralization at Burfjord are also host to elevated levels of rare elements (e.g., Indium), which are critical "technology metals" that are important to the emerging green energy and other industries. Discrete zones of cobalt and nickel mineralization are also present at Burfjord.
Norden Crown entered into an option agreement (the "Agreement") with Boliden in respect to Burfjord (see

Forward‐looking statements are statements that are not historical facts and are generally, but not always, identified by the words "expects", "plans", "anticipates", "believes", "intends", "estimates", "projects", "potential" and similar expressions, or that events or conditions "will", "would", "may", "could" or "should" occur. Forward-looking statements may include, without limitation, statements relating to future outlook and anticipated events, such as the successful completion of the exploration program (consisting of diamond drilling, mapping, prospecting, outcrop sampling, airborne magnetic and ground electromagnetic geophysical surveys) and Norden Crown's belief in the economic potential and attractiveness of Burfjord as a bulk tonnage target as discussed herein, the dates the various segments of the exploration program will commence, the duration of various segments of the exploration program, the anticipated timing of the results of the exploration programs described herein and the planned uses of the resulting data. Although Norden Crown believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance, are subject to risks and uncertainties, and actual results or realities may differ materially from those in the forward-looking statements. Such material risks and uncertainties include, but are not limited to, the ability of the various contracted entities to complete their duties within the time expected by the Company; inclement weather conditions that may impede, delay or stop all or part of the exploration program; the effects of the Covid-19 pandemic or other pandemics or epidemics; mechanical breakdowns of equipment used in the exploration programs, changes in economic conditions or financial markets; the ability of Norden Crown to obtain the necessary consents required to explore, drill and develop the projects and, if obtained, to obtain such consents in a timely fashion relative to Norden Crown plans and business objectives for the projects; the general ability of Norden Crown to drill test its projects and find mineral resources; if any mineral resources are discovered or acquired, the Company's ability to monetize any such mineral resources; and changes in environmental and other laws or regulations that could have an impact on the Company's operations. Forward-looking statements are based on the reasonable beliefs, estimates and opinions of Norden Crown management on the date the statements are made.
