Questcorp Mining Expands Marisa Target with Stronger Depth-Related IP Chargeability at North Island Copper Project

Questcorp Mining Inc. (CSE: QQQ) (OTCQB: QQCMF) (FSE: D910) (the "Company" or "Questcorp") is pleased to report preliminary results from a recently completed 12.8 line-kilometre Induced Polarization ("IP") survey over the Marisa Zone at its 100%-optioned North Island Copper Project, located near Port Hardy on Vancouver Island, British Columbia. The survey results indicate a significant increase in the intensity of the chargeability anomaly at depth, suggesting that historical drilling conducted in 1992 likely intersected only the upper, lower-intensity portion of a potentially larger mineralized system. Key Takeaway: - Chargeability anomaly strengthens from approximately 150 metres depth to the 400- metres survey limit - Historical drilling appears to have tested only the outer shell of the system - Results support the potential presence of a larger porphyry system at depth "The results from the 2026 IP survey significantly enhance our understanding of the Marisa target," said Saf Dhillon, President & CEO of Questcorp Mining. "The increase in chargeability with depth suggests that historical drilling did not fully test the core of the system. With the continued success of North Isle Copper & Gold to the west and now a refined geophysical model in place, we are excited to continue advancing toward drill testing to evaluate the full scale of the target." The 2026 IP survey was completed on 200-metre spaced lines oriented at an azimuth of 045°, using parameters of a=100 metres and n=9, allowing for greater depth penetration relative to historical work. Peter E. Walcott & Associates Ltd. integrated the new survey data with historical IP data collected in 1992 by Pacific Geophysical Ltd. The historical survey utilized similar line spacing but shallower parameters (a=50 metres and n=4), limiting depth resolution. The combined dataset has been used to generate a 3D inversion model, effectively producing a higher-resolution interpretation. The integration of both datasets provides an equivalent 100-metre line spacing, enhancing confidence in the continuity and geometry of the chargeability anomaly. 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) Copper grades in DDH92-03 were observed to increase with depth, consistent with the interpretation that drilling may have intersected the upper portion of a larger mineralized system. The expanded and intensified chargeability response at depth, combined with increasing copper grades in historical drilling, supports the interpretation of a potential larger, vertically extensive mineralized system at the Marisa Zone. The Company plans to: - Initiate permitting for a follow-up drill program - Design drilling to test the core of the chargeability anomaly at depth - Further refine targets using the 3D inversion model
