Questcorp Mining Completes Induced Polarization Survey at the Marisa Zone - North Island Copper Project

Rhea-AI Summary

Questcorp Mining (OTCQB: QQCMF) completed 12.8 line kilometres of induced polarization (IP) surveying over the Marisa Zone at the 1,168-hectare North Island Copper Project near Port Hardy, BC.

The company will integrate 1992 historical IP data with the new 2026 survey to produce a 3D inversion model to help define priority drill targets. Permitting for a drill program is targeted for late H1 or early H2 2026. Historical drill intercepts reported copper mineralization but the company cautions the historical data has not been independently verified.

Positive

• Completed 12.8 km of induced polarization surveying over Marisa Zone
• Plan to integrate 1992 IP data with 2026 survey to build a 3D inversion model
• Targeting permitting for a drill program in late H1 or early H2 2026

Negative

• Historical drill intercepts show low reported grades: 0.078% Cu over 56.39 m and 0.041% Cu over 70.71 m
• Historical exploration data referenced has not been verified by a Qualified Person
• Advancement to drilling remains conditional on final interpretation and permitting timelines

Vancouver, British Columbia--(Newsfile Corp. - March 11, 2026) - Questcorp Mining Inc. (CSE: QQQ) (OTCQB: QQCMF) (FSE: D910) (the "Company" or "Questcorp") is pleased to announce the successful completion of 12.8 line kilometres of induced polarization ("IP") surveying over the Marisa Zone at its 1,168-hectare North Island Copper Project located near Port Hardy on Vancouver Island, British Columbia.

The Company is currently reviewing the newly acquired geophysical data and will release a detailed interpretation once the technical team has completed its evaluation. As part of this process, Peter E. Walcott and Associates Limited will integrate the historical 1992 IP survey data with the new 2026 survey results to generate a comprehensive 3D inversion model of the target area.

The results of this work are expected to assist in defining priority drill targets. Subject to final interpretation and permitting timelines, the Company intends to initiate permitting for a drill program in late H1 or early H2 2026.

Previous exploration at the Marisa Zone identified copper mineralization associated with an IP chargeability anomaly. In 1992, two of five diamond drill holes were completed to test the anomaly intersected copper mineralization, including:

• 0.078% copper over 56.39 metres (DDH92-01)
• 0.041% copper over 70.71 metres (DDH92-03)

Both intercepts were encountered within altered quartz diorite, with copper grades increasing with depth in DDH92-03.

"This recently completed IP survey represents an important step in advancing the Marisa Zone target," stated Saf Dhillon, President & Chief Executive Officer of Questcorp Mining. "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 program later in 2026."

The Company cautions that a Qualified Person has not verified the historical exploration data referenced in this release. The presence of mineralization on adjacent or nearby properties, including NorthIsle Copper and Gold and BHP properties, is not necessarily indicative of mineralization on the North Island Copper Project.
