Correction: Kopsa gold-copper resource grows 37% to 0.75 million gold-equivalent ounces, with grade increasing 10% to 1.13 grams per tonne gold-equivalent

Stockholm, 23 January 2024. Northgold AB (Nasdaq First North Growth Market: “NG”, or “Northgold” or the “Company”) announces its 2024 Mineral Resource Estimate (“MRE”) for the 100%-owned Kopsa gold and copper project in Central Finland, incorporating 2,000 metres (“m”) of expansion drilling completed at the project last year, for which assay results were previously reported.

Highlights

• Kopsa in-situ resources increase to 749,500 ounces gold-equivalent (“AuEq”) within 20.7 million tonnes (“Mt”) grading 0.88 grams per tonne (“g/t”) gold (“Au”) and 0.17% copper (“Cu”), for combined grade of 1.13 g/t AuEq, containing 585,100 ounces (“oz”) Au and 75.6 million pounds (“Mlbs”) Cu (68% in the Measured and Indicated categories).
• Resources increase by 203,000 oz AuEq, the majority of which are in the Inferred category.
• The increase reflects a southward expansion and a doubling of depth, from nine step-out holes completed last year, including deepest hole NGKOP23034 and its major intersection.
• The higher resource grade is attributed to an increased cut-off grade of 0.5 g/t AuEq (was 0.3 g/t AuEq), as the substantial size increase allows for more focus on higher-grade zones.
• Improved MRE size and grade establishes Kopsa as a globally significant gold project, and as a likely candidate to be one of Finland’s next gold mines.
• Additional exploration potential exists in multiple directions, with the deposit’s expanded lateral and depth extents creating new opportunities for resource extensions.
• Northgold’s total compliant resources in central Finland increase to 0.99 Moz AuEq, meeting the Company’s initial 1 Moz target stated during the 2022 initial public offering (“IPO”).
• The Kopsa 2024 MRE was prepared in accordance with standards set out in 2012 Australasian Code for Reporting of Exploration Results, Mineral Resources, and Ore Reserves (JORC code).

Henrik Löfberg, Interim CEO and Board member, comments: “I am excited to see Kopsa’s advancement materializing in the way Northgold’s founders had hoped it could. This increase to near 1 million ounces at a 10%-improved grade puts Kopsa on the map as a globally significant project, and solidifies its position as one of the largest undeveloped gold projects in Finland.”

Mitch Vanderydt, P.Eng, MBA, Advisor and Former CEO, comments: “This result certainly landed at the top end of my expectations. At the rate they are going, the Northgold exploration team is likely only a few thousand metres of drilling away from reaching the 1 million ounce gold-equivalent milestone at Kopsa, above which economics for a stand alone mine and mill should start to look quite robust, as would be confirmed by future studies.“

About the Kopsa mineral resource estimate
This 2024 MRE incorporates a total of 23,000m of core drilling, including 2,000m of drilling completed by Northgold at Kopsa in 2023, in addition to the 4,200m completed by Northgold in 2022 and also incorporated into the previous 2023 MRE (see press release 23 August 2023), and 16,800m of historic drilling completed by others.

A summary of the Kopsa 2024 MRE is shown in Table 1, with its block model shown in Figure 1. The MRE was prepared by Pekka Lovén and Markku Meriläinen (who also prepared the historic 2012 estimate by others and the 2023 estimate by Northgold), under the supervision of Hannu Makkonen, PhD, who is an Independent Qualified Person in compliance with JORC code. Similar conservative assumptions were made a in the previous 2023 MRE, although a higher cutoff grade of 0.5 g/t AuEq was applied. A Technical Report supporting the MRE is also being prepared in accordance with JORC code, and will become available on the Company’s website at www.northgoldab.com.

Approximately 96% of the growth in resource ounces occurred along the southern and lower boundaries of the previous 2023 MRE envelope (see Figures 2 and 3), based on the results of last year’s drilling which included deep drill hole NGKOP23034’s major intersection of 0.99 g/t AuEq over 105.7m from 208.2m, which had doubled the known depth extents of the south-southwest dipping main mineralized zone. The remaining some 4% of the increase in ounces occurred in shallow zones just north of the 2023 MRE boundary, based on some newly incorporated bedrock surface assays coupled with a more refined geologic model, which helped extend the deposit northward by up to 50m laterally along part of the deposit’s north edge (adding a small, shallow 0.3 Mt grading 0.71 g/t Au and 0.12% Cu, to the north side of the resource, and suggesting additional northward resource growth potential).

As a result of the increased size of the resource, and the new opportunities for substantial further resource extensions it has created, the higher cut-off grade of 0.5 g/t AuEq (from 0.3 g/t AuEq in 2023 MRE) was selected to allow the exclusion of lower-grade zones and an increase to the overall grade, at the expense of losing relatively few additional lower-grade, gold-equivalent ounces. At a lower cut-off grade of 0.3 g/t AuEq that was applied to the 2023 MRE, the 2024 MRE would have increased to 792.0 koz AuEq grading 1.03 g/t AuEq (45% more ounces than 2023 MRE at the same grade), according to the MRE’s grade-tonnage relationship.

Near-term additional exploration potential exists (see Figure 2 and 3) not only southward to build upon last year’s drilling success, including around the 377m long, 250m step-out hole NGKOP23034 (see press releases dated 20 September 2023 and 2 November 2023 for reported assays). But also northward, both around the newly delineated shallow resources along the deposit’s edge, and also extending further to the north and northeast for up to 300m, where some dozen historic drill holes (including many drilled in unfavourable orientations) encountered gold and copper mineralization (see Figures 2 and 3) that now appears in reach to be incorporated into the growing Kopsa resource pit shell, following some additional drilling in this area.

Northgold has now increased Kopsa resources by more than 0.2 Moz AuEq in each of its last two drill seasons (see Figure 4). This has resulted in attractive overall resource accumulation rates of 101 oz AuEq/m drilled from the 2,000m last year, and 52 oz/m drilled from the 4,200m drilled in 2022, both of which exceed the overall project resource accumulation rate to date of 33 oz/m (historic drilling was more focused on upgrading resources to measured and indicated categories while Northgold has been and is more focused on growth), creating a strong and efficient resource growth trajectory (see Figure 4) for a project that is already one of Finland’s largest undeveloped gold deposits.

Updated company-wide mineral resources now total 0.99 Moz AuEq, with a combined average grade of 0.94 g/t Au and 0.13% Cu (1.36 g/ AuEq) as shown in Table 2, which meets the Company’s initial 1Moz goal stated during the 2022 initial public offering (“IPO”).

2. The Mineral Resource Estimate was prepared by Pekka Lovén and Markku Meriläinen, under the supervision of Hannu Makkonen, PhD, who is an Independent Competent Person in compliance with JORC Code.
3. Estimates were based on a lower cutoff grade of 0.5 g/t AuEq for the for combined gold and copper mineralisation deemed potentially mineable by open pit methods, and were top-cut to 20 g/t Au in the high grade gold domains. Both the cut-off grade and gold-equivalency conversions are based on a gold price of US$1,500/oz Au and copper price of US$3.25/lb Cu. No recoveries or dilution factors have been considered in this estimate and the results should be considered strictly in situ, in accordance with JORC Code’s reporting guidelines for resources.

5. All values are rounded to reflect the relative accuracy of the estimate.
6. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
7. Resource tonnage is rounded to nearest 10,000. Contained ounces are rounded to nearest 100. Contained kilograms and contained tonnes are rounded nearest 10.
8. Discrepancies in the totals or percentages are due to rounding effects.
