Questcorp Mining has finalised an induced polarisation (IP) survey covering 12.8-line kilometres at the Marisa Zone, part of its North Island Copper Project in British Columbia (BC), Canada.
The project is situated on 1,168 hectares (ha) of land near Port Hardy on Vancouver Island.
The company is analysing the recent geophysical data and will publish a detailed report once the evaluation by the technical team concludes.
Peter E. Walcott and Associates has been tasked with incorporating historical data from a 1992 IP survey with the latest findings to create a thorough 3D inversion model of the area.
The comprehensive model aims to assist in identifying priority drill targets.
Questcorp plans to start the permitting process for a drilling programme late in the first half (H1) or early H2 2026, contingent on final interpretations and permitting timelines.
Past exploration at the Marisa Zone uncovered copper mineralisation linked to an IP chargeability anomaly.
In 1992, two out of the five diamond drill-holes tested this anomaly, intersecting copper mineralisation.
Drill-hole DDH92-01 revealed 0.078% copper over 56.39m, while DDH92-03 showed 0.041% copper over 70.71m.
Both intercepts were found within altered quartz diorite, with increasing copper grades observed with depth in DDH92-03.
Questcorp Mining president and CEO Saf Dhillon said: “This recently completed IP survey represents an important step in advancing the Marisa Zone target. The survey has successfully confirmed the presence of the historical chargeability anomaly identified in earlier work.
“Once Walcott and Associates completes the 3D inversion and our technical team finishes reviewing the results, we expect to refine potential drill targets and move toward a drill programme later in 2026.”
In November 2025, the company secured an initial investment from Sorbie Bornholm, a UK-based institutional investor.
The company received C$2m ($1.42m) to continue work on its primary projects and for general working capital needs.
“Questcorp Mining completes IP survey at BC’s North Island Copper Project” was originally created and published by Mining Technology, a GlobalData owned brand.
