Northgold AB (publ) announced positive gold and copper assay results from the final six drill holes completed as part of 2023 resource extension drilling at its flagship Kopsa gold and copper project in central Finland, all of which encountered significant gold and copper mineralization outside of the previously defined resource envelope. Highlights: These results build on the success and resource growth potential of the previously announced strong results that had doubled the depth of known mineralization in central portions of the Kopsa deposit; Four of the drill holes are located southwest (SW) of the deposit near its west end and intersected broad gold-copper mineralization up to 125 metres (m) away from the existing resource envelope, and up to 50m below it; The two other drill holes are located south-southeast (S-SE) of the deposit, just east of the previously announced strong results, and intersected broad gold-copper mineralization up to 75m away from the existing resource envelope, that confirmed and broadened main zone mineralization, including in previously undrilled zones within the pit shell; Kopsa 2023 drilling totalled 1,993m, of which 896m were within highlighted mineralized intervals being incorporated into an updated resource estimate that is already underway, and also point to additional resource growth potential; Highlights from S-SE expansion hole NGKOP23029 include:1.54 g/t grams per tonne ("g/t") gold-equivalent ("AuEq") over 4m, including 0.97 g/t gold ("Au") and 0.38% copper ("Cu") from 5.4m downhole depth (3.8m vertical depth), 1.40 g/t AuEq over 33.1m (1.05 g/t Au and 0.23% Cu) from 38.35m (27.1m), 0.98 g/t AuEq over 20.5m (0.84 g/t Au and 0.09% Cu) from 83.8m (59.3m), 0.91 g/t AuEq over 105.2m (0.77 g/t Au, 0.10% Cu) from 112.6m (79.6m), including: 13.06 g/t AuEq over 3.4m (12.88 g/t Au and 0.12% Cu) from 135.7m (96m). Highlights from S-SE expansion hole NGKOP23030 include: 1.04 g/t AuEq over 7.7m (0.91 g/t Au and 0.09% Cu) from 72m (50.9m), 0.79 g/t AuEq over 120.4m (0.58 g/t Au and 0.14% Cu) from 102.4m (72.4m).

Highlights from SW expansion hole NGKOP23026 include: 0.53 g/t AuEq over 29.9m (0.35 g/t Au and 0.12% Cu) from 15.1m (11m); 0.87 g/t AuEq over 13.05m (0.60 g/t Au and 0.18% Cu) from 18.55m (13.6m), 0.58 g/t AuEq over 23.6m (0.44 g/t Au and 0.10% Cu) from 102.8m (75.2m). Highlights from SW expansion hole NGKOP23027 include: 0.67 g/t AuEq over 46.05m (0.48 g/t Au and 0.13% Cu) from 38.1m (27.9m), 0.49 g/t AuEq over 14.9m (0.34 g/t Au and 0.10% Cu) from 139.8m (102.2m). Highlights from SW expansion hole NGKOP23028 include: 0.46 g/t AuEq over 130.3m (0.34 g/t Au and 0.08% Cu) from 36.9m (27m), including: 1.33 g/t AuEq over 24.35m (1.06 g/t Au and 0.18% Cu) from 74.75m (54.7m).

Highlights from SW expansion hole NGKOP23033 include: 0.49 g/t AuEq over 53.9m (0.33 g/t Au and 0.11% Cu) from 13.9m (10.2m), including:1.12 g/t AuEq over 12.9m (0.81 g/t Au and 0.21% Cu) from 17.7m (12.9m), 0.34 g/t AuEq over 137.2m (0.26 g/t Au and 0.05% Cu) from 82.6m (60.4m), including: 0.59 g/t AuEq over 48.8m (0.45 g/t Au and 0.09% Cu) from 82.6m (60.4m).
