NORDEN CROWN INTERSECTS HIGH-GRADE COPPER AT BURFJORD JV COPPER-GOLD PROJECT
Norden Crown Metals Corp. has released results from 12 completed diamond drill holes from two reconnaissance programs during 2021 (totalling 3,179.2 metres) at its Burfjord copper-gold project. Significant drill results include 30.1 m of 0.28 per cent copper in hole 003, 17.2 m of 0.34 per cent Cu in hole 004 and 12 m of 1.27 per cent Cu in hole 011. A list of significant drill intercepts is presented ("Burfjord drill intersects" table). Drilling at Burfjord was completed on time and under budget despite weather-related difficulties during the winter program.
Burfjord is host to numerous high-grade veins, with associated copper-rich envelopes developed across a large area (approximately six by four kilometres). The large associated alteration system and widespread copper mineralization supports Burfjord's potential to host a large copper deposit.
"The combined Boliden and Norden teams are very pleased with the results from this follow up drill program, which continues to outline broad zones of copper mineralization surrounding high-grade copper veins at Burfjord," stated Patricio Varas, executive chairman. "This drill program has identified copper zones situated within the copper endowed and broadly altered Burfjord Anticline and confirms our theory that these rocks have the potential to host a sizable mineral discovery on the property. The large exploration program approved by Boliden for 2022 is an endorsement of our joint belief that Burfjord has real potential for finding a significant deposit".
Only limited exploration has taken place at Burfjord in the modern era before Norden Crown's recent reconnaissance drill programs. The best historical drill intercept consists of seven metres at 3.6 per cent copper
and was obtained from the Cedarsgruve (mine) area in the northern portion of the claim block. Previous drilling by Norden Crown at Burfjord returned compelling results, including an intercept of 32 metres averaging 0.56 per cent copper and 0.26 g/t gold (including 3.46 metres of 4.31 per cent copper and 2.22 g/t gold) at shallow depths below a cluster of historical mine workings.
Overview of the Burfjord project
The project, located in the Kafjord copper belt near Alta, Norway, is highly prospective for iron-oxide-copper-gold (IOCG) and sediment-hosted copper mineral deposits, which contribute significantly to copper production globally.
Burfjord comprises six exploration licences totalling 5,500 hectares. Within the licence area, during the nineteenth century, copper mineralization was mined from over 30 historical mines and prospects developed along the flanks of a prominent four-by-six-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 to 5 per cent copper are surrounded by envelopes of stockwork veins or disseminations of copper mineralization extending 10s to 100s 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 multicentimetre scale) disseminations in the veins. The sodium-rich (highly saline) styles of alteration and mineralization at Burfjord are also host to geochemically elevated levels of rare elements. Discrete zones of cobalt and nickel mineralization are also present at Burfjord.
Burfjord joint venture terms
Norden Crown entered into an option agreement with Boliden in respect to Burfjord (see June 10, 2020, news release). In order to earn its 51-per-cent interest in the project, Boliden must finance 100 per cent of the exploration programs by spending $6-million (U.S.) over the next four years. Work on the exploration programs is directed by a join Norden-Boliden technical committee.
Quality control, quality assurance and core handling protocols
Drill core is logged and prepped for sampling before submittal to ALS in Mala, 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 per cent less than two millimetres), and rotary split into two fractions. One is retained (coarse reject) and the other is pulverized to 85 per cent less than 75 micrometres. Pulps are analyzed by ultratrace ICP-MS (ME-MS61) and ICP-AES (Au-ICP22). Over detection limit samples are reanalyzed using ore-grade four-acid digestion (plus-OG62) and in the case of high-grade copper (Cu-OG62).
