Kopsa down-dip expansion with high-grade at depth also extends westward

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 program across its 100%-owned Kopsa and Kiimala Trend projects in central Finland. Today’s announced gold assays represent another three drill holes from Kopsa. One drill hole (NGKOP22014) targeted westward extensions to down-dip expansions of gold and copper mineralization along the south edge of the deposit, and the other two (NGKOP22022 & NGKOP22023) targeted further delineation of the central higher-grade zone. All three drill holes encountered significant gold mineralization, including the down-dip expansion highlight of 0.72 grams per tonne (“g/t”) gold (“Au”) over 83.2 metres (“m”) including 5.27 g/t Au over 1.9m at depth. This extends the previously reported down-dip expansion with high-grade at depth by another 100m westward to a total length of 300m, which remains open to the west where gold (and copper) assays are still pending for drill hole NGKOP22015.

Highlights

Down-dip southwest continuation

Highlighted gold assays from drill hole NGKOP22014 (copper assays are still pending) include:

• 0.72 g/t Au over 83.2m from 79.5m depth along hole (60.0m vertical depth), including:

    • 2.25 g/t Au over 6.1m from 82.5m (62.3m vertical), which includes

        • 5.00 g/t Au over 2.3m from 86.3m (65.1m vertical)

    • 2.01 g/t Au over 8.1m from 125.2m (94.5m vertical), which includes

        • 5.27 g/t Au over 1.9m from 125.2m (94.5m vertical)

Further central higher-grade zone delineation

Highlighted gold assays from drill hole NGKOP22022 (copper assays are still pending) include:

• 2.48 g/t Au over 45.85m from 29.45m (18.9m vertical), including

    • 5.91 g/t Au over 7.2m from 32.8m (21.1m vertical), and including

    • 4.03 g/t Au over 5.8m from 49.5m (31.8m vertical), and including

Highlighted gold assays from drill hole NGKOP22023 (copper assays are still pending) include:

• 1.32 g/t Au over 65.1m from 5.9m (4.5m vertical)

Drill hole locations are shown in Table 1 and Figure 1.

Gold assay results are shown in Table 2 and Figures 2.

Today’s announced down-dip expansion hole NGKOP22014 was drilled southwest of the Kopsa resource outline and outside the extents of historic drilling. The drill hole intercepted a down-dip continuation (or expansion) of the main mineralized zone, with the goal of growing resources. This down-dip expansion was also observed up to 300m to the east along the edge of the deposit in previously reported drill holes, NGKOP22010 and NGKOP22006 (see press released dated 10 November 2022), and NGKOP22007, NGKOP22008, and NGKOP22009 (see press release dated 24 November 2022). Collectively, these five previously reported down-dip expansion drill holes intercepted broad intervals (ranging from 34.45 to 112.5m wide along hole) of low-grade gold (grading 0.52 to 0.66 g/t Au) from moderately shallow depths (ranging from 37.8 to 79.3m vertical), and consistently included discrete higher-grade intervals (2.07 to 12.91 g/t Au over 0.75 to 10.15m) at depth (from 93.8 to 125.7m vertical depth).

Today’s announced results for drill hole NGKOP22014 extend this previously reported down-dip expansion by roughly 100m westward, to a total length of roughly 300m, and similarly encountered a broad interval of (slightly higher-grade) low-grade gold from moderately-shallow depths (see today’s highlighted intercept of 0.72 g/t Au over 83.2m from 60.1m vertical), which similarly also included a narrower, higher-grade interval at depth (see today’s highlighted sub-interval of 5.27 g/t Au over 1.9m from 94.5m vertical) which continues to justify the need for more follow-up drilling at depth to better understand the higher-grade, long-term potential at depth. As such, focused deeper drilling at Kopsa is currently being planned as part of the Company’s funded 3,000m 2023 diamond drilling program, which is set to begin late in the first quarter of 2023, with further details on the exploration plans to be announced early in 2023.

Today’s announced drill holes NGKOP220022 and NGKOP22023 were planned to follow-up on the success of previously reported drill hole NGKOP22001, which targeted the inner-core of the central higher-grade zone, and which encountered the best gold intercept to date on the project of 3.90 g/t Au over 98.7m from 4.2m vertical (see press release dated 2 August 2022). Today’s two reported holes in this area did not target the inner-core of the central higher-grade zone, but rather nearby gaps in historic drilling and modeled mineralization to further delineate the variation and extents of the already fairly densely drilled central higher-grade zone, which was successfully achieved with today’s announced highlighted intercepts of moderate-grade gold (1.32 to 2.48 g/t Au) over broad intervals (45.85m to 65.1m along hole) from relatively shallow depths (4.5 to 18.9m vertical). These two holes will also provide additional important core samples that (together with historic drill core samples that the Company also possesses) will be representative of some of the initial mineralized material to be mined at Kopsa, and which will be used for further metallurgical and ore sorting test work that is planned to re-start in 2023 (following-up on historic test work that continues to be reviewed and analyzed), with further details to be announced early in 2023.

Mitch Vanderydt, CEO, comments: “We like to see this down-dip expansion with high-grade at depth extend westward to a total length of roughly 300m along the south edge of the Kopsa deposit, as was observed in drill hole NGKOP22014, especially given the slightly higher-grade of 0.72 g/t Au in the broad interval which exceeds the comparable broad interval grades encountered in all five previously reported down-dip expansion holes to the east. Also, the further delineation of the central higher-grade zone as was observed in drill holes NGKOP22022 and NGKOP22023 helps fill-in gaps in historic drilling and will allow for further tightening the resource estimate, as well as will provide additional core samples (for metallurgical and ore sorting test-work) that will be representative of this important zone that will be the first to be mined.”

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 25 drill holes totalling 4,241m at the flagship Kopsa project. Today’s announced results represent gold assays for three drill holes. Including today’s announcement, gold assays have now been reported for 13 drill holes (see also press releases dated 2 August, 23 August, 10 November, and 24 November 2022) and are pending on the remaining 12 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. Kopsa 2022 drill results will culminate to an interim update to the Kopsa 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. Multiple sulfide-bearing zones were observed in portions of the Pirttineva core.
