Nickel sulphide explorer Nordic Nickel Limited (ASX: NNL ; Nordic, or the Company ) is pleased to report further assay results from drilling completed at its flagship Pulju Nickel Project (the Project ) in the Central Lapland Greenstone Belt ( CLGB ) of northern Finland.
Assays from diamond drillholes HOT002, HOT003 and HOT006, part of the Company’s maiden diamond drilling program at the Hotinvaara Prospect ( Hotinvaara ), have confirmed and extended the footprint of nickel mineralisation intersected by historical drilling ( Figure 1 & Appendix 1 ).
HOT003 and HOT006 encountered multiple near-surface disseminated sulphide zones as well as discrete zones of semi-massive and net-textured massive sulphides [2] . The grade of the mineralisation intersected is consistent with the current Mineral Resource Estimate ( MRE ) for Hotinvaara of 133.8Mt @ 0.21% Ni and 0.01% Co[3] .
1 HOT003 and HOT006 true widths estimated to be 60-80% and 80-90% of downhole widths, respectively.

3 ASX release “Nordic Delivers Maiden 133.6Mt Mineral Resource – 278,520t Ni and 12,560t Co”, 7th July 2022.
The Phase 1, 22,000m drilling program at Hotinvaara is focused on a dual exploration strategy of targeting high-grade massive nickel-copper sulphides of a similar style to the nearby world-class Sakatti Deposit and bulk tonnage-style disseminated nickel sulphide mineralisation with the potential to host long-life Mineral Resources.
Management Comment
Nordic Nickel Managing Director, Todd Ross, said: “ Nordic’s maiden drill campaign continues to confirm historical drilling and, importantly, expand the mineralisation footprint at Hotinvaara. The wide intersections of shallow disseminated nickel sulphides we are seeing in the assays bodes well for when we re-evaluate the Mineral Resource at the end of the Phase 1 drilling program.
“The high-grade nickel sulphide intersections are highly encouraging, confirming that the mechanisms for the massive sulphide formations were operating at Hotinvaara.
“When drilling re-commences after the northern summer break, our activities will continue to focus on zones of both known and potential massive sulphides and systematically step-out from historically drilled areas with the aim of expanding the Mineral Resource. Based on what we are seeing at Hotinvaara, the Company believes that the Pulju project has the potential to host multiple world-class nickel deposits and thereby produce for many generations the critical minerals desperately needed for the energy transition.”

Drillhole summaries
Nordic’s diamond drilling and assay results confirm those from the historical drilling as well as increasing the mineralisation footprint and confidence level of the MRE ( Figure 2 ). Significantly, near-surface disseminated nickel mineralisation has been intersected consistently by drilling. Following is a brief description of the three new drillholes for which assay results have recently been received. Full details of the assay results are provided in Appendix 1 .

Colour code: blue Ni-sulphide/Ni-total>50%; Red: Nisulphide/Ni-total<50%.
Drillhole HOT002
Drillhole HOT002 was positioned near the northernmost extent of the known mineralised zone and designed to test multiple geological and geophysical targets, including the basal ultramafic sequences where magma interacted with a regionally extensive evaporite (including anhydrite) sequence.
HOT002 intersected an interlayered sequence of ultramafics, ultramafic skarn and schists down to 165m and appears to lie near the edge of, rather than within, the main mineralised channel. It did not intersect the basal sequences as planned, however, a zone of disseminated nickel mineralisation grading 49.85m @ 0.18% Ni from 119.5m was intersected in an area not currently in the MRE[4] .
Drillhole HOT003
Drillhole HOT003 was also positioned to test multiple geological and geophysical targets, including the basal ultramafic sequences, and the eastern part of the MRE. Electromagnetic features being targeted included FLEM, MLEM and borehole EM (BHEM) conductor plates.
HOT003 deviated significantly from its planned trajectory due to drilling and geological factors, however, several promising geological features and mineralised zones were intersected, providing

Additional key observations and interpretations from HOT003 include:
Upper ultramafics and host rocks
- An extensive zone of ultramafic-hosted disseminated nickel sulphides was intersected nearsurface, confirming historical drilling. Assay highlights from this zone include 63.8m @ 0.22% Ni, 0.01% Co from 140.2m and 63m @ 0.22% Ni, 0.01% Co from 211m ( Figure 3, Table 1 ).
4
-
Ultramafics interacted with a significant number of basin-related sediments and volcanics in the upper 300m. This observation correlates with that in HOT001 and drilling elsewhere in the CLGB where the comingling is interpreted to be important for the accumulation of nickel sulphides.
-
The presence of mineralised black schists, including semi-massive sulphide accumulations ( Figure 4 ), in the upper sequences may indicate a secondary mineralisation event is present in Pulju. Anomalous copper mineralisation was also intersected for the first time in these sequences, including 10.8m @ 0.34% Ni, 0.02% Co, 0.12% Cu from 140.2m , incl. 1m @ 0.24% Ni, 0.01% Co, 0.27% Cu from 140.2m and 1m @ 0.33% Ni, 0.02% Co, 0.2% Cu from 149m.
-
A high-grade sulphide vein of 0.4m @ 1.68% Ni, 0.06% Co from 288m is hosted by ultramafic/dunitic rock ( Figure 5 ), rather than within the volcano-metasedimentary sequence. This indicates that sulphide accumulation dynamics were favourable.
-
Intersection of anhydrites supports the interpretation that the Pulju Belt is highly prospective for massive nickel-copper sulphide mineralisation as this association is known to occur elsewhere in the CLGB (e.g. Sakatti and Kevitsa).

Mid-level ultramafics
-
Deeper, non-prospective ultramafics and skarns were intersected between 304m to 549m. These units contained a relatively low proportion of nickel-in-sulphide ( Figure 3 ) and suggests the source magma, or its interaction with the country rock, was not conducive to the formation of sulphides.
-
Of importance is the lateral variation in nickel-in-sulphide ( Ni-S ) versus nickel-total ( Ni-T ) in the mid-level ultramafics. Historic drillhole HOV040, which intersected the same ultramafic unit at shallower depths, intersected predominantly high Ni-S/Ni-T.

Drillhole HOT006
Drillhole HOT006 was positioned in the southwest of the Hotinvaara prospect area and targeted geophysical anomalies, including a magnetic high/gravity low with a sharp gradient that potentially reflects intense serpentinisation of the ultramafic host rocks. It was also designed to test the extent of the MRE in this area along with FLEM and BHEM conductors. Assay highlights from HOT006 are provided in Table 2 with full assay results detailed in Appendix 1 .
Lithologies intersected in HOT006 are correlated with the upper ultramafic sequences and host rocks observed in HOT003. Lithologies include albitised schists, peridotite, serpentinite, ultramafic skarn, quartzite and volcano-sedimentary sequences. An extended intersection of ultramafichosted disseminated nickel mineralisation was observed near-surface, grading 199.1m @ 0.22% Ni from 20.9m ( Figure 7, Table 2 ). Importantly, mineralisation extended between gaps within the MRE which is encouraging for a potentially substantial resource upgrade in this region.
Below the existing MRE, drillhole HOT006 intersected another ultramafic unit interpreted to represent a different magmatic pulse or phase to the upper ultramafic unit that hosts the MRE. This unit contains interlayers of relatively high Ni-S/Ni-T and relatively low Ni-S/Ni-T and highlights the dynamics of the magmatic system. Of significance in the lower unit is a very high-grade, large (~20mm), near pure pentlandite (Ni sulphide) bleb within the ultramafic host rock ( Figure 6 ) from which the encompassing sample assayed 0.6m @ 4.66% Ni, 0.1% Co from 359.6m . This represents the highest single Ni assay result from Nordic’s drilling on the Project to date and confirms that processes were operating to concentrate Ni-sulphides and allow them to grow within the magmatic system.

Nickel-in-sulphide assays
Nickel-in-sulphide (Ni-S) partial leach assay results from HOT002, HOT003 and HOT006 support similar assay results from HOT001 and earlier first-pass mineralogical and chemical test work completed by Metso:Outotec on the project that determined between 83% and 94% of the measured total nickel was Ni-S[5] .
For drillhole HOT002, an average of 85% of total nickel occurs as Ni-S. Partial leach assay results from the upper sequences of HOT003 (5.4-304m) indicate that 85% of total nickel occurs as Ni-S ( Figure 3 ). The mid-level ultramafics in HOT003 (304-549m) are deficient in Ni-S with 31% of total nickel occurring as Ni-S. The lowest ultramafic sequences in HOT003 (553-652.1m) return to being more enriched in nickel sulphide, with 90% of total nickel occurring as Ni-S, before the low Ni-S cumulate returns with 21% of total nickel occurring as Ni-S ( Appendix 1 ).

7
Similar to HOT003, the upper ultramafic units of HOT006 (20.9-366m) have a relatively high nickel sulphide contents with 81% of total nickel sourced from Ni-S ( Figure 7 ). The lower ultramafic body has variable nickel sulphide contents, with between 17% and 86% total nickel sourced from Ni-S.
Drilling update
As of 30[th] June 2023, twenty (20) drillholes for 12,385.2m had been completed at Hotinvaara ( Figure 1 , Appendix 2 ). All drillholes in the current program are designed to test both geological and geophysical targets (MLEM, BHEM, fixed loop EM, gravity and magnetics) and expand the MRE.
Drilling is currently paused for a planned break during the northern hemisphere summer and will recommence in early August 2023. Batches of samples are being regularly submitted for core cutting and assaying. Assay results are anticipated to be received every 3-4 weeks.

• Outokumpu Oy did regional exploration in the area which was followed by drilling in the 1980s and 1990s (51 drillholes completed). • The Hotinvaara area was later held by Anglo American (2003 - 2007) who completed 6 diamond drillholes and regional bottom-of-till sampling. |
||||||||
| Geology • Deposit type, geological setting and style of mineralisation. |
• The main commodity of economic interest at Hotinvaara is nickel. Minor copper has also been intersected. The main economic minerals are pentlandite and chalcopyrite. The bulk of the mineralisation occurs as disseminated sulphides but there is also semi-massive to massive sulphide veins with high nickel grades. • The main mineralised rock types are komatiites, dunites, serpentinites and metaperidotites (ultramafic cumulates). Also, some mineralisation is hosted by ultramafic skarn. • The Pulju greenstone Belt is located in the western part of the Central Lapland greenstone Belt. The Pulju Belt covers an area of ~10km x 20km. |
