Surge Copper is progressing a large-scale regional exploration program across the combined Ootsa and Berg district which is designed to test multiple exploration targets prospective for primary porphyry copper style deposits, related breccia style deposits, and secondary hydrothermal precious metal style deposits.

The prospectivity of this district is well established, with the known resources at the Berg, Seel, and Ox deposits representing an approximately 30-kilometre belt that encompasses the Huckleberry mine and mill complex. Beyond these deposits, there are numerous prospects at varying stages of advancement with historical exploration work ranging from geological mapping, soil surveys, and various sparse geophysical datasets, to limited shallow drilling.
Much of the approximately 1,200 km2 contiguous mineral claim block is low-elevation ground with thick forest and variable till cover, necessitating the use of systematic sampling and remote sensing exploration methods. Exploration activities in the region benefit from active timber harvesting operations and the access roads developed as part of this industry.
In 2021, to support focused regional exploration efforts, Surge commissioned a district-wide airborne passive electromagnetic geophysical survey using the Z-axis Tipper EM system (ZTEM). This geophysical method exploits the interaction between the subsurface and naturally occurring, long-wavelength atmospheric EM fields which penetrate deep into the Earth’s crust to map the subsurface distribution of electrical resistivity and magnetism. Information from this survey represents a powerful tool for mapping large-scale regional structures, and the potential presence of subsurface intrusive systems and related alteration zones, which are necessary precursors to porphyry-style mineral deposits. The images below are selected representations of the data covering the full Ootsa and Berg claim blocks, highlighting the abundance of large-scale linear structural features and subcircular features which often occur at terminal points of linear features. The known deposits at Berg, Seel, and Ox, represent strong “true-positive” geophysical signatures for large-scale porphyry copper deposits, and aid in the interpretation of the numerous other look-alike signatures throughout the district.
