Questcorp Mining has recently completed an induced polarisation (IP) survey covering 12.8-line kilometres at the Marisa Zone, which is part of the North Island Copper Project located in British Columbia (BC), Canada.
Situated on 1,168 hectares (ha) of land near Port Hardy on Vancouver Island, the project holds significant potential for copper mineralisation. The company is currently analysing the geophysical data gathered from the recent survey and plans to release a detailed report once the technical team completes their evaluation.
To enhance their understanding of the area, Questcorp has enlisted the expertise of Peter E. Walcott and Associates to integrate historical data from a 1992 IP survey with the latest findings. This collaboration aims to create a comprehensive 3D inversion model of the Marisa Zone, which will assist in identifying priority drill targets for future exploration.
The company is gearing up to commence the permitting process for a drilling programme later in the first half (H1) or early in the second half (H2) of 2026. This timeline is dependent on the final interpretations of the geophysical data and the permitting procedures.
Previous exploration at the Marisa Zone has revealed copper mineralisation associated with an IP chargeability anomaly. In 1992, two out of the five diamond drill-holes tested this anomaly, with drill-hole DDH92-01 uncovering 0.078% copper over 56.39m and DDH92-03 showing 0.041% copper over 70.71m. Both intercepts were found within altered quartz diorite, with increasing copper grades observed at depth in DDH92-03.
Questcorp Mining’s president and CEO, Saf Dhillon, expressed optimism about the recent IP survey results, stating that it marks a significant advancement in the exploration of the Marisa Zone. The confirmation of the historical chargeability anomaly through the survey sets the stage for refining potential drill targets and progressing towards a drilling programme later in 2026.
In November 2025, Questcorp secured an initial investment from Sorbie Bornholm, a UK-based institutional investor, to support its primary projects and general working capital needs. The company received C$2m ($1.42m) from this investment, enabling them to continue their exploration efforts at the North Island Copper Project.
