Additional drill results extend the Kopsa deposit along strike to the west
Northgold AB (Nasdaq First North Growth Market: “NG”, “Northgold” or the “Company”) is pleased to announce additional resource expansion diamond drilling (“DD”) results from its completed 2022 DD program across its 100%-owned Kopsa and Kiimala Trend projects in central Finland. Today’s announced gold assays represent another five drill holes from Kopsa that targeted along-strike extensions to gold and copper mineralization up to 60 metres (“m”) west of the existing deposit. All five drill holes encountered significant gold mineralization (with copper assays pending) aimed at being incorporated to mineral resources.
Highlights
Highlighted gold assays from drill hole NGKOP22011 (copper assays are still pending) include:
- 1.23 grams per tonne (“g/t”) gold (“Au”) over 14.6m from 74m depth along hole (54.1m vertical depth), including:
- 2.58 g/t Au over 4.75m from 78.65m (57.5m vertical)
Highlighted gold assays from drill hole NGKOP22012 (copper assays are still pending) include:
- 0.73 g/t Au over 8.8m from 7.2m (5.3m vertical), including
- 1.75 g/t Au over 2.8m from 7.2m (5.3m vertical)
Highlighted gold assays from drill hole NGKOP22013 (copper assays are still pending) include:
- 0.60 g/t over 29.6m from 11.1m (8.1m vertical), including
- 1.18 g/t Au over 10.3m from 26.8m (19.6m vertical), and
- 0.53 g/t Au over 19m from 55.4m (40.5m vertical), including
- 4.10 g/t Au over 1.1m from 57.8m (42.3m vertical)
Highlighted gold assays from drill hole NGKOP22019 (copper assays are still pending) include:
- 0.62 g/t over 79m from 14m (10.2m vertical), including
- 1.05 g/t Au over 34.4m from 15m (19.6m vertical), which includes
- 2.21 g/t Au over 6.95m from 36.55m (26.7m vertical).
- 1.05 g/t Au over 34.4m from 15m (19.6m vertical), which includes
Highlighted gold assays from drill hole NGKOP22020 (copper assays are still pending) include:
- 0.63 g/t over 54.9m from 23m (16.8m vertical), including
- 1.02 g/t Au over 19.35m from 42.2m (11m vertical), and including
- 2.35 g/t Au over 1.3m from 76.6m (56.0m vertical), and
Drill hole locations are shown in Table 1 and Figure 1.
Gold assay results are shown in Table 2 and Figure 2.
These five drill holes were located up to 60m west of the limit of historic drilling and all successfully intercepted continuations of gold mineralization, thereby extending the length of the deposit along strike to the west. All five drill holes encountered broad intervals (ranging from 9.8 to 79m wide along-hole) of low-grade gold mineralization (0.60 to 1.23 g/t Au) beginning from shallow to moderately shallow depths (from 5.3 to 54.1m vertical), which should help grow gold mineral resources either by expanding previously defined mineralized zones or by infilling of zones previously defined as waste rock. Notable apparent expansions to gold mineralization include in drill holes NGKOP22019 and NGKOP22020 which were drilled from south of the western end of the existing resource outline and which encountered substantial gold mineralization up to roughly 40m south and up to roughly 40m above the previously understood generalized envelope of gold and copper mineralization (see Figure 2), and in drill holes NGKOP22011 and NGKOP22012 which were drilled north of the western end of the existing resource outline and which encountered a northern up-dip continuation of the previously defined mineralized zones (in NGKOP22012, see Figure 2) as well as discovered a new possible parallel zone below the existing deposit (in NGKOP22011, see Figure 2) that may require future follow-up. Narrower, higher-grade intervals from deeper, moderate depths were also encountered in four of the five drill holes (ranging from 2.21 to 4.1 g/t Au over 1.1 to 6.95m along-hole, beginning from 26.7 to 57.5m vertical), which continue to suggest possible future underground potential, pending further study and future drilling. Recall, this deeper, higher-grade potential was also reflected in recently reported 2022 drill holes located along the south edge of the deposit (see press releases dated 21 December, 24 November, and 10 November 2022) as well as in those located in more central portions of the deposit (see press releases dated 2 August and 23 August 2022).
Mitch Vanderydt, CEO, comments: “These drill results not only extend the length of the Kopsa deposit along strike to the west by up to 60m to a total length of 700m, but also demonstrate that the deposit still remains open to the west, which had not been previously understood and which will warrant additional step-out holes to the west as part our 2023 drill program that is currently being planned with more details to be announced soon.”
Kopsa Historic Resource Estimate
Kopsa hosts a historic resource estimated at 16.3 million tonnes (“Mt”) at 0.81 g/t Au and 0.16% copper (“Cu”) for 423,600 ounces (“oz”) Au, or 554,600 oz gold equivalent (“AuEq”) at 1.06 g/t AuEq, the majority of which falls in the Measured and Indicated (“M&I”) category in accordance with Canada’s National Instrument (“NI”) 43-101 standards. See Northgold’s Independent Geologists Report (“IGR”) on the Company’s website for more information.
Update on the Completed 2022 DD Program
The completed 2022 DD program included 4,241 m at the flagship Kopsa project. Including today’s announced five holes, gold assays have now been reported for 18 drill holes (see also press releases dated 2 August, 23 August, 10 November, 24 November, and 21 December 2022) and are pending on the remaining seven drill holes (in addition to the deeper portion of hole NGKOP22010). Copper assays are pending on all 25 holes. Additional assay results from Kopsa are due to be announced in the coming weeks, as they are received from the assay lab and processed. Kopsa 2022 drill results will culminate to an interim updated resource estimate, which is scheduled to be completed during the first and second quarters of 2023, with results due to be released before the end of the second quarter of 2023.
The DD program also included another five DD holes totalling 695 m at Pirttineva (totalling 4,936m drilled company-wide during 2022), a previously un-drilled prospect at our Kiimala Trend project that looked promising based on a recently completed Induced Polarization (IP) geophysical survey and outcrop samples (see press release dated 12 September 2022), with assays pending and due to be announced in the coming weeks, as they are received from the assay lab and processed. Multiple sulfide-bearing zones were observed in portions of the Pirttineva core.
Update on 2023 Exploration Planning
Planning is ongoing for the Company’s fully-funded 3,000m 2023 diamond drilling program that will be aimed at continued resource growth and new discoveries, and will once again incorporate both Kopsa and Kiimala Trend projects. The drill program is set to begin late in the first quarter of 2023, with further details on plans to be announced in the coming weeks, pending the ongoing and incoming assay results, and based on the results of additional Induced Polarization (IP) geophysical surveys that are being completed across additional southern portions of Kiimala Trend.

Quality assurance and quality control (QA/QC)
Drill core was logged, sampled and cut in half by a diamond saw in a secure core storage facility located in Pyhäsalmi Mine site, Finland. The core samples for drill holes NGKOP22011, NGKOP22012 and NGKOP22013 were sent to Eurofins Mineral Testing laboratory in Oulu, Finland, for sample preparation. From Oulu, the samples were sent to Eurofins Mineral Testing laboratory in Sodankylä for PbO fire assay and ICPOES analysis (method code: 705P). Eurofins Mineral Testing Finland is accredited according to ISO/IEC 17025 by FINAS. The core samples for drill holes NGKOP22019 and NGKOP22020 were sent to ALS Geochemistry laboratory in Outokumpu, Finland, for sample preparation. From Outokumpu, the samples were sent to ALS Hub laboratory in Loughrea, Ireland, for PbO fire assay and ICPOES or gravimetric analysis (method code: Au-ICP22 for <10 ppm Au and Au-GRA22 for >10 ppm Au samples). The ALS laboratories are accredited according to ISO/IEC 17025 standard approved by FINAS. Certified reference standards and blanks were included in the sample batches. In two standard assays out of 26 a deviation, low in absolute value (+0.021 - +0.045 g/t Au) but relatively notable (+9.3% - +19.6%) was observed. Otherwise no QA/QC issues were noted with the results reported herein and their values allow the public disclosure of the assay results.
