Drills 364.2 Metres Of 0.27% Cueq At Kwanika


Northwest Copper (TSX.V: NWST) has released results from four holes drilled in the northern lobe of the Kwanika deposit's central zone. These holes returned long intercepts of copper and gold mineralization. Highlights include:

  • K-22-237 -- 364.2 metres of 0.27 per cent CuEq from 27.8 metres to 392 metres, including:
  • 24.55 metres of 0.86 per cent CuEq from 229.3 metres to 253.85 metres.
  • K-22-238 -- 167.85 metres of 0.32 per cent CuEq from 33.55 metres to 201.4 metres.

"These holes confirm that strong copper and gold mineralization continue in the northern portion of Kwanika Central Zone," said president and chief executive officer Peter Bell. "These holes demonstrate that the Kwanika system contains a cluster of deposits over three kilometers, from South Zone to these recent holes in the north of the Kwanika Central Zone. Further drilling results are expected from the South Zone at Kwanika as well as our other projects in the coming weeks."

Drill Results Discussion

We have now released results from 20 of the 30 drill holes competed at Kwanika in 2022. We anticipate that we will continue to publish results from the 2022 program over the remainder of the year.

Diamond drill holes K-22-237, 238, and 246 were designed to target structurally controlled higher-grade mineralization in the northern portion of the Central Zone. They complement previously released drill holes K-22-234, 235, 236, 239, 241, 243, 244 and 245. The results of all of these holes collectively demonstrate continuity of grade within the currently defined resource. Including the previously reported holes, the northern portion of the Central Zone was drilled over approximately 450 metres in strike length and results demonstrate that mineralization continues to the north of the conceptual open pit. All three holes in this release hit mineralization that is relatively shallow with overburden cover ranging from 27.80 to 43.50 metres down-hole depth. Results from the drilling in the northern extent of the conceptual open pit will also help constrain our structural and geological models and help focus future exploration programs.

K-22-237 has the longest intercept with 364.20 metres of 0.27 per cent CuEq. This intersection is on the same section as K-22-236 that was reported as 179.60 metres with 0.33 per cent CuEq, and the two holes demonstrate continuity of grade on this section. Hole K-22-237 also intersected mineralization below the current conceptual open pit and could add value to the project in the future. Mineralization in K-22-237 is hosted in andesites to 117.85 metres depth with strong pervasive propylitic alteration and chalcopyrite hosted in quartz-sulphide veins. This is followed by diorite with strong pervasive propylitic alteration and an overprint by potassic alteration. The copper mineralization is in chalcopyrite and occurs as disseminations and in quartz-sulphide veins that become the predominant style of mineralization downhole. From 277.50 metres to end of hole the dominant alteration is pervasive potassic alteration and chalcopyrite occurs as disseminations and hosted in quartz-sulphide veins.

K-22-238 was drilled on a section approximately 90 metres to the north of K-22-237. It intersected 167.85 metres grading 0.32 per cent CuEq and is on the same section as K-22-241 that was previously reported at 305.75 metres with 0.29 per cent CuEq. Again, these two holes show grade continuity in the conceptual open pit area. Mineralization in K-22-238 is hosted by diorite with strong pervasive propylitic alteration that is locally overprinted by moderate to strong potassic alteration. Chalcopyrite occurs in quartz-sulphides veins and as disseminations.

K-22-246 was drilled in the northern extent of the conceptual open pit area and returned 145.70 metres of 0.20 per cent CuEq including 64.60 metres of 0.28 per cent CuEq with most of this intersection sitting outside of the current conceptual open pit volume. Mineralization is hosted by diorite with moderate pervasive propylitic alteration along with irregular zones of pervasive potassic alteration. Chalcopyrite mineralization is either disseminated or hosted in quartz-sulphide veins or both. Results from this hole further demonstrate that the mineralized system is present and is potentially open to the north of the current proposed open pit.

K-22-247 was drilled approximately 600 metres north-northwest of the conceptual open pit and tested a geophysical induced polarization anomaly. The drill did not intersect significant mineralization but it did intersect geology that explains the anomaly, as well as faults that validate our current structural geology model.
