NORTHWEST COPPER REPORTS STRONG GOLD RESULTS FROM DRILLING AT EAST NIV

Northwest Copper Corp. has released the results from the eight-hole 2022 East Niv project drilling campaign, including strong gold results of over seven grams per tonne gold (7.88 g/t gold equivalent) over a short interval and lower grades over longer intervals. The stronger gold mineralization surrounds the copper-dominant mineralization encountered in the 2021 campaign. These results, combined with the large surface copper anomaly reported in 2022 and the copper-gold mineralization encountered in 2021, outline a large mineralized system within a large property position (43,297 hectares). Highlights from the current release are presented herein:

• ENV-22-013 -- 100.8 metres at 0.44 g/t AuEq (0.24 g/t gold, 0.1 per cent copper and 0.4 g/t silver) from 637 metres;
• ENV-22-018 -- 124.86 metres at 0.38 g/t AuEq (0.22 g/t Au, 0.07 per cent Cu and 0.7 g/t Ag) from 457.05 metres;
• ENV-22-016 -- 0.5 metre at 7.88 g/t AuEq (7.35 g/t Au, 0.13 per cent Cu and 21.9 g/t Ag) from 303 metres;
• ENV-22-017 -- two metres at 2.48 g/t AuEq (2.33 g/t Au, 0.07 per cent Cu and 0.8 g/t Ag) from 416 metres.

"East Niv is a new project, with the first holes drilled in 2021. The 2021 program identified strong copper and gold mineralization in one part of the property, and the 2022 program expanded this system, with gold-dominant results from this campaign. We have also identified a very large copper-at-surface anomalous zone, as described in 2022," said president and chief executive officer Peter Bell. "In just 24 months, we have taken East Niv from an exciting exploration concept to a project with two identified zones of mineralization, several exciting drilling intercepts and multiple exploration targets."

Exploration discussion

The 2022 program at East Niv has expanded the size of the copper-gold system identified in 2021 as well as added new surface targets. New holes drilled in and around the porphyry copper-gold-silver (plus or minus molybdenum) system encountered gold-dominant mineralization in a zone overprinted by strong illite-pyrite and chlorite-pyrite alteration. This suggests that the company is drilling the upper and/or peripheral parts of a large, preserved porphyry system. Two thousand twenty-two drilling increased the length of the porphyry hydrothermal system to approximately four kilometres, which remains open along strike, at depth and to the southwest. Reconnaissance drilling elsewhere on the property also encountered strongly altered volcanic and intrusive rocks that contain strongly anomalous copper, gold, zinc and other metals typical of settings peripheral to porphyry deposits.

Surface sampling during geological mapping has identified a trend of high-grade, bornite-rich copper-silver veins that is at least 13 kilometres in length. These veins indicate the presence of additional porphyry centres or of a distinct style of high-grade exploration target.

2022 drill results discussion

The current drilling results at East Niv suggest that the company is drilling the upper and/or peripheral parts of a large, preserved porphyry system. The gold-dominant intervals intersected in some holes are interpreted to be a peripheral signature, particularly where they are accompanied by a polymetallic signature. The alteration, polymetallic signatures and geophysical patterns all show a strong northwest-southeast control on the hydrothermal system, which is open along strike, at depth and to the southwest. This provides a sound geological model and exploration search space for future drill targeting. The exploration potential is strengthened by the large land position, the potential for the known porphyry system to grow in size, and widespread alteration and mineralization in reconnaissance drilling and surface sampling. Future exploration will focus on developing a robust geological model vectoring to the core of the known porphyry system, using advanced geochemistry, geology and geophysical modelling.

Eight drill holes were completed in 2022, building off the 10 drill holes that were completed in 2021. Fourteen of the total drill holes have demonstrated that the porphyry copper-gold-silver (plus or minus molybdenum) discovery in hole ENV-21-004 is within a very large and strong hydrothermal system that remains open in most directions.

East Niv exhibits classic characteristics for porphyry deposits in the Quesnel and Stikine terranes. Mineralization occurs in both mafic volcanic rocks of the Takla Group and in associated intermediate intrusions, where it is associated with biotite-quartz-magnetite and potassium-feldspar-rich potassic alteration. Mineralization is commonly overprinted by strong illite-pyrite and chlorite-pyrite alteration, which suggests that the company is drilling the upper and/or peripheral parts of the porphyry system.

Drill holes ENV-22-013 and ENV-22-018 intersected gold-copper mineralization, of generally modest grade due to overprints by pyritic alteration. Viewing these holes in conjunction with holes from 2021, they show that Cu-Au-Ag (plus or minus Mo) mineralization was originally continuous over at least 1,100 metres along strike and across an unknown width southwest to northeast.

Drill holes ENV-21-009 and ENV-22-011 are the most southeasterly and northwesterly holes in the discovery area. They contain strong propylitic alteration with a polymetallic signature and document a porphyry system at least four kilometres long that remains open along strike, to depth and to the southwest.

Hole ENV-22-014 was drilled to the north from 100 metres north of the discovery drill hole. It initially intersected geochemically anomalous intrusive rock, but then encountered a fault, across which is mafic volcanic rock with pyritic alteration that has a polymetallic signature of zinc and arsenic with locally anomalous gold.

The extent of these drill holes, the numerous and volumetrically abundant intrusions, the strength of alteration, the abundance of pyrite, the extent of subsurface geochemical enrichment, and the high copper-gold grades encountered in the discovery hole confirm East Niv as a large and strong porphyry magmatic-hydrothermal system.

The remaining four holes -- ENV-22-012, ENV-22-015, ENV-22-016 and ENV-22-017 -- were drilled on other parts of the large property to test other targets and to obtain subsurface data to combine with the company's substantial 2022 geological mapping program and aid continued exploration at East Niv.

The four drill holes drilled outside the discovery area establish that strong hydrothermal activity is also present in other parts of the East Niv property. Hole ENV-22-015 was drilled five km northwest of discovery hole ENV-21-004. The entirety of hole 15 has strong propylitic alteration in mafic volcanic rocks, abundant pyrite, and a polymetallic signature of zinc, arsenic, lead, silver and gold.

Drill hole ENV-22-016 was drilled at the South Nub target, located 2.5 km south of the discovery hole, and also encountered mafic volcanic rocks with propylitic alteration and abundant pyrite, along with a similar polymetallic signature. This hole also had a large intersection of intermediate intrusive rock that contains significant molybdenum mineralization, with individual analyses of up to 799 parts per million.

Hole ENV-22-017 was drilled 2.3 km east of the South Nub showing, near a previously unknown intrusion discovered during surface mapping. This hole first encountered weakly altered mafic volcanic rocks that have a weak association between anomalous gold and arsenic, but after passing through a fault, the volcanic rocks have much stronger propylitic alteration with pyrite and a marked increase in copper, gold and other metals.

Hole EN22-012 was drilled 2.3 km north-northeast of the discovery hole, where it intersected strongly magnetic, unaltered and unmineralized volcanic rocks, achieving its goal to determine the cause of a strong aeromagnetic anomaly.

Drilling and mapping completed across the East Niv project in 2021 and 2022 confirm the excellent exploration potential on the property. Exploration shows that intrusions are more numerous, larger and compositionally more varied than had been recognized historically. Most importantly, strong, sulphide-rich hydrothermal alteration with strongly anomalous metal signatures is widespread on the property. Faults commonly juxtapose different types of rocks with different characteristics of hydrothermal alteration and mineralization, which means that Cu-Au-Ag (plus or minus Mo) mineralization originally formed at different paleodepths could be preserved across the property.
