Northisle Copper and Gold Inc. announced that it has commenced its 2024 Phase I exploration program at the North Island Project. Pemberton Hills Results and Exploration: 2023 drilling at Pemberton Hills was successful in confirming the overall exploration thesis regarding the southwest tilt of the 6.5 km long by 1.4km thick lithocap, and the orientation of the very large hydrothermal system at Pemberton Hills extending to the northeast of this. The underlying system is evidenced by a 1.5km wide by 2.5km long QSP alteration zone at surface.

QSP alteration usually occurs peripherally to potassic alteration hosting copper mineralization. Drill holes PH23-12 and PH23-13 confirmed the extent and orientation of this hydrothermal system and shows where the drill holes are interpreted to have intersected the porphyry system. Drill hole PH23-12 was drilled proximal to the lithocap and was oriented to pierce magnetic and induced polarization (IP) anomalies adjacent to a QSP altered quartz-diorite.

The hole showed significant QSP alteration and minor chalcopyrite bearing quartz stockwork veining, which indicates progression towards the source of the system but did not contain economically significant mineralization. PH23-13 was drilled further from the lithocap to the northeast and targeted in the direction of a large magnetic anomaly. The drill hole intercepted QSP alteration which again indicates proximity to potassic alteration.

Examining the drill results in association with magnetic survey data and historic surface sampling, which included copper and gold values within at least 200m long narrow quartz veins, the current interpretation is that the possible source occurs south of the 2023 drill holes and north of the historic surface samples. This interpretation is in the context of surface geology and alteration. The 2024 surface exploration at Pemberton Hills will include a detailed surface mapping program targeted at obtaining additional structural information, sericite speciation, chlorite proximitor analysis, quartz and gypsum vein density mapping and rock geochemistry information which will aid in future drill targeting.

The target areas in the context of previous drilling and surface magnetics. Hushamu Exploration: At Hushamu, the Company has reviewed drill core, logging, and surface exploration over the last several years, as well as results of drilling from other targets on the property. There are now multiple indicators that the Hushamu deposit, like Northwest Expo, is lithocap hosted.

In addition, the orientation of the overall porphyry system has been reinterpreted which indicates that the causative intrusion may be to the south of the Hushamu resource, rather than to the north. Evidence for this reinterpretation includes: the presence of zunyite, a fluorine bearing mineral like topaz occurring in the upflow zone of porphyry deposits; the discovery in a recent bulldozed area of sheeted and stockwork quartz veining over 600m, plus leached stockwork quartz veining with residual jarosite, goethite and hematite grading 0.1% to 0.5% copper on the south side of the Hushamu deposit; and the observation of gusano texture, which commonly occurs in lithocaps above hydrothermal upflow zones of porphyry deposits in adjacent drill holes to the north. Northisle will be conducting a mapping program similar to that at Pemberton Hills, which will obtain additional structural and vectoring information in order to support drilling in this new target area.
