MOVING LOOP ELECTROMAGNETICS (MLEM)
Electromagnetic geophysical surveys (EM) have been confirmed by drilling as the most effective targeting tool in the exploration for high-grade copper sulfides at the Storm Project. Multiple historical surveys using both airborne and ground EM systems have resulted in the discovery of most of the known copper mineralization in the Storm area.
The near-surface (<100m depth) high-grade copper mineralization in the immediate Storm area remains open along strike and at depth, with recent drilling resulting in new discoveries both in the near-surface and at depth. Together with the largely untested 100km-long prospective copper target horizon, this highlights the outstanding potential for the discovery of additional copper mineralization in the near-surface, at depth, and over considerable lateral extents within the larger project area.
The planned EM surveys will utilize the most powerful energy source to date (more than twice as powerful as prior surveys). They will aim to fill gaps in the historical surveys, acquire higher-resolution data, and investigate deeper. The surveys will also expand the search into new areas including the Blizzard, Tornado, and Tempest Prospects.
Storm
Moving Loop Electromagnetics (MLEM) will begin in the Storm area where historical surveys have been instrumental in expanding areas of known mineralization and in the discovery of new zones, such as the 2023 discoveries at Thunder (48.6m @ 3.0% Cu in drill hole ST23-03) and Lightning Ridge (30.4m @ 2.2% Cu in drill hole SR23-52). The EM anomalies tested to date in the Storm area have been strongly correlated with higher-grade (>2%) copper mineralization.
The 2024 Storm MLEM surveys will include:
- Ultra-high-resolution Moving Loop Electromagnetics (MLEM) to focus on the expansion of the known copper mineralization and making new discoveries. The targeted search space will be approximately 0-200m below surface.
- Deep-penetrating, wider-spaced MLEM to explore the Storm central graben area and below the known mineralization. The targeted search space will be from 200-500m vertical depth
