Unleashing Mineral Potential: Expanding Nickel-Copper Exploration with Advanced Geophysical Techniques

“Advanced exploration projects plan to complete approximately 100,000 metres of drilling over the next 21 months.”

In the ever-evolving landscape of mineral exploration, the quest for nickel-copper deposits has taken a significant leap forward. As we delve into the latest industry trends, we’re witnessing an unprecedented expansion in polymetallic mining projects, driven by ambitious drill program plans and cutting-edge geophysical techniques. This comprehensive update sheds light on how exploration activities are scaling up, with a focus on extending mineralized zones, expanding mineral resource estimation, and exploring untapped areas with high potential.

The Big Picture: Scaling Up Exploration

Power Metallic Inc., a frontrunner in the nickel-copper exploration sector, has recently secured a substantial exploration budget of over C$40 million through to the end of 2026. This significant financial backing sets the stage for an extensive drilling campaign, targeting approximately 100,000 metres over the next 21 months. The scope of this ambitious project encompasses:

Extending zones in the Lion and Tiger polymetallic areas
Expansion of the Nisk deposit
Exploring the untested 5.5 km strike between these areas

Currently, the company operates with three drill rigs, but plans are underway to double this capacity to six rigs by June. This expansion is contingent on upgrading the core logging and sampling facilities at the site, a process expected to be completed by May.

Advanced Geophysical Techniques: The Game Changers

At the heart of this exploration strategy lies the utilization of advanced geophysical techniques. Power Metallic is leveraging both borehole electromagnetic surveys (BHEM) and ground EM as primary tools for drill targeting. These methods have proven instrumental in identifying off-hole anomalies, leading to successful discoveries of sulfide mineralization.

“Borehole electromagnetic surveys are being utilized for precise targeting in nickel-copper exploration projects.”

The integration of various geophysical data sets is a key aspect of the exploration strategy:

Ground EM
Ground magnetics
Gravity surveys
Surface geological mapping

This multi-faceted approach allows for a comprehensive understanding of the subsurface, enhancing the precision of drill targeting and increasing the likelihood of significant discoveries.

Exploration Zones: A Closer Look

Lion Zone

The Lion zone continues to be a focal point of exploration, with ongoing drilling extending its plunge. Recent drill holes (PN-24-086, 087, 092, 093, 096, 097, and 100) have all intersected the Lion zone, showcasing significant visual mineralization. The company is eagerly awaiting assay results from these promising intersections.

Moreover, BHEM surveys conducted on holes west of Lion have indicated strong off-hole plates, presenting new targets for immediate follow-up.

Tiger Zone

Following the initial intersection at Tiger in hole PN-24-094, located 700 meters east of Lion, BHEM surveys identified multiple conductive off-hole plates. Subsequent drilling targeting these plates resulted in sulfide intersections both west (PN-25-098) and east (PN-25-099) of the initial hole. Visual logging and XRF results indicate the presence of copper and nickel mineralization, though assays are still pending.

The company has further expanded westward from hole PN-25-098, successfully hitting sulfides in hole PN-25-101. As more drilling information accumulates, Power Metallic aims to provide a comprehensive interpreted model for the Tiger zone.

Between Lion and Tiger

A significant development has occurred in the area between the Lion and Tiger zones. A semi-completed BHEM survey on drill hole PN-24-088, located approximately halfway between the two zones, revealed an off-hole anomaly. By combining this data with a previous airborne EM anomaly, the team successfully intersected sulfide mineralization in drill hole PN-25-102. This discovery provides compelling evidence that mineralization potentially connects along the entire Lion to Tiger trend.

Nisk Area

Exploration in the Nisk area is focused on expanding the Mineral Resource Estimate (MRE) from January 2024. The program aims to establish Nisk’s potential as a larger Ni/Cu/Co/PGE deposit and investigate indications of Lion-style polymetallic mineralization on the fringes of the main deposit.

A recent drill hole targeting an off-hole BHEM conductor intersected a narrow massive sulfide zone with exceptionally high nickel and cobalt tenors, significantly above previous metal values at Nisk. This discovery opens up the possibility of a new deposit hybrid in the Nisk camp.

Future Exploration Plans

As Power Metallic prepares to scale up to six operating rigs by June, detailed planning is underway to maximize the efficiency and effectiveness of the exploration program. The current strategy includes:

Four drills dedicated to the Lion-Tiger area, focusing on:
- Expanding Lion and Tiger zones
- Developing the ‘in-between zones’
- Following up on BHEM Lion west targets
- Infill drilling on Lion for a potential 1H 2026 mineral resource estimate (MRE)
Detailed geological mapping as snow melts
Possible soil and till sampling to identify subsidiary mineralization zones
Revisiting and expanding the 2023 Ambient Noise Tomography (ANT) survey
Integration of 3-D magnetic and gravity modeling

To support the potential Lion MRE, work is currently underway to determine the mineralogy of the deposit, focusing on the habit of base metals (Cu, Ni) and the deportment of PGEs, Au, and Ag. This information will inform a future metallurgical study expected in the second half of 2025.
