GoldHaven Resources Corp. expanded its high-resolution airborne geophysical survey over its Magno Project in northern British Columbia on May 29, 2026 [4].

The expansion aims to identify a significant new mineral deposit by utilizing technology that previously contributed to a major copper discovery in Idaho. By increasing the scope of its data collection, the company intends to refine its drill targets for the 2026 season.

The company increased the survey area by approximately 30% [1], bringing the total to 2,237 line-kilometres [2]. This survey is being conducted over the Magno Project, located within the Cassiar District of northern British Columbia. GoldHaven Resources holds 100% ownership of the project [3].

Airborne geophysical surveys allow exploration companies to detect subsurface anomalies without the immediate need for ground-based drilling. This specific high-resolution approach is designed to provide a more detailed map of the geological structures in the Cassiar District, a region the company is targeting for its next major discovery.

The data gathered from these 2,237 line-kilometres [2] will be used to support the company's 2026 drill targeting strategy. This process involves analyzing magnetic and electromagnetic data to pinpoint the most promising locations for physical exploration.

GoldHaven Resources is listed on the CSE as GOH, the OTCQB as GHVNF, and the FSE as 4QS. The company said the expanded survey is part of its broader effort to scale up exploration activities in the province.

“The company increased the survey area by approximately 30%”

The expansion of the geophysical survey indicates that GoldHaven Resources is moving from a broad regional assessment to a more targeted exploration phase. By applying technology proven in other jurisdictions like Idaho, the company is attempting to reduce the geological risk associated with the 2026 drilling program, which requires precise targeting to be cost-effective.
