Northisle Copper and Gold

Northisle Copper and Gold (TSXV:NCX) announced today that it intersected 0.72% Cu Eq. over 50m, 0.47% Cu Eq. over 101m at the North Island Copper and Gold Project. The drilling effectively extends mineralization more than 200m beyond the modelled pit shell. The assay results come from the 2022 Spring drill program at Hushamu, and continue to affirm the interpretation that higher-grade mineralization lies within under-drilled areas of the currently modelled pit at the deposit.

HU22-06 showed it continued in copper mineralization for at least 200m past the outline of the originally modelled pit shell. 

Highlights from the assay results are as follows: 

  • 2022 drilling at the Hushamu deposit (“Hushamu”) of the North Island Copper and Gold Project (the “North Island Project”) has continued to demonstrate potential to improve Mineral Resource grade and tonnage within the existing Hushamu pit design area
  • HU22-01, HU22-02 and HU22-05 each extended higher-grade mineralization into areas which are currently modelled to contain waste or lower-grade mineralized material
  • In addition, HU22-06 indicates mineralization continues into alteration previously interpreted as unmineralized, more than 200 m beyond the existing modelled pit shell boundary.

Robin Tolbert, Vice President of Exploration at Northisle commented in a press release: “Drilling at Hushamu during early 2022 continues to demonstrate the potential for improved grade and tonnage at Hushamu. In addition, we have demonstrated that historical visual interpretations of the alteration profile at Hushamu may have underestimated the overall size of the mineralized portion of the system.”

Hushamu 2022 Drill Results

Northisle has now received the assay results of the six drill holes from its 2022 Spring drill program at Hushamu (HU22-01 to HU22-06), which has the objective of converting in-pit Inferred Mineral Resources to Indicated Mineral Resources ahead of the Company’s planned pre-feasibility study. The mineralization remains open to the northwest and southeast of the deposit, and based on results released today is interpreted to be open at depth significantly past previous modelling. 

The significance of the additional 2022 Spring infill holes at Hushamu are:

  • HU22-01 shows significant mineralization extends from hole H-12-03 along the base of the proposed pit bottom. This may add tonnes and maintain the mineral grades over a longer distance than previously estimated.
  • HU22-02 shows a thicker combined mineralized interval than holes EC-184 and H-12-09 on either side of it. An additional hole will be drilled in the gap between these two holes.
  • HU22-03 and HU22-04 were infill holes drilled to the south of the main mineralized zone. Both intersected leached altered zones with a few narrow copper intercepts >0.01% Cu.
  • HU22-05 was part of a two-hole program to fill in the gap between H-12-08 and H17-02 and test the extent below the planned pit bottom. This hole showed mineralization extends to this point but not to depth. An in-fill hole between this hole and H17-02 is required to test to the south of an interpreted fault along Section 5613600E.
  • HU22-06 indicates that mineralization extends significantly beyond the modelled outline of the 2021 PEA pit shell on Section 581000 E:
    • Historical drilling generally ends at the interpreted interface of CMG alteration and propylitic alteration.
    • XRF scanning of drill core in real time indicated that core contained copper below the previously interpreted bottom of CMG alteration, so drilling was continued.
    • Results suggest future drilling should continue to greater depth and may represent a significant extension of mineralization.
  • The spring drilling program continues to demonstrate the potential to improve tonnage and grade in an updated Mineral Resource estimate at Hushamu through both upgrading of existing blocks as well as extension of the overall orebody.
