Questcorp Mining Expands Marisa Target with Stronger Depth-Related IP Chargeability at North Island Copper Project
Deeper IP anomaly at North Island hints at untapped copper, but drill test still pending
Questcorp Mining released preliminary results from a 12.8 km induced‑polarization (IP) survey over the Marisa Zone of its 100 % optioned North Island Copper Project (Vancouver Island, BC).
- The new IP data show chargeability intensity rising from ~150 m to the 400 m depth limit, implying a larger and deeper porphyry system than indicated by historic 1992 drilling.
- Management plans to seek permitting and design a follow‑up drill program aimed at testing the core of this deepened anomaly later in 2026.
- No resource estimate or economic assessment is disclosed; the release is classified as “Non‑Material – Positive” by the company.
| Aspect | Assessment |
|---|---|
| Novelty | The deeper chargeability signal is new information beyond the 1992 drill results, but it remains a geophysical inference without drilling confirmation. |
| Market expectation | Prior updates (Feb‑Mar 2026) announced the start and completion of the IP survey; investors anticipated forthcoming interpretation. This result confirms the survey’s success but does not yet deliver a drill‑ready target. |
| Magnitude | The anomaly suggests potential for additional copper at depth, which could materially increase the project’s size if confirmed. However, the probability of economic discovery remains speculative. |
| Overall materiality | Given the early stage (geophysics only) and lack of any change to financing or corporate structure, the news is Routine – Positive: a positive incremental update that aligns with expectations but does not yet shift valuation materially. |
Questcorp Mining is an exploration company focused on two flagship assets:
-
North Island Copper Project (Vancouver Island, BC) – 100 % optioned porphyry copper target (Marisa Zone). Historic 1992 drilling intersected low‑grade copper; the current IP survey aims to delineate deeper chargeability that may host higher‑grade mineralization.
-
La Union Gold & Silver Project (Sonora, Mexico) – 100 % optioned CRD‑style gold‑silver‑zinc district with recent high‑grade chip‑channel intercepts (20 g/t Au, 226 g/t Ag) and a newly discovered sediment‑hosted gold zone at Luis Hill.
Both projects are at early exploration stages; no NI 43‑101 resource has been declared.
