Segment Reporting [Abstract] |
Segment reporting | 16. Segment reporting: The Company’s President & Chief Executive Officer is the Chief Operating Decision Maker (“CODM”) of the Company. The CODM evaluates how the Company allocates resources, assesses performance and makes strategic and operational decisions. Based upon such evaluation, the Company has determined that it has four reportable segments. the Company’s reportable segments are the Santa Cruz Copper Project, critical metals, data processing and energy storage. The Santa Cruz Copper Project and critical metals segments are focused on mineral project exploration and development with a focus on identifying and developing mineral projects, and ultimately mines, associated with the metals necessary for electrification. The Santa Cruz Copper Project is at a more advanced stage relative to most of the Company’s other mineral exploration projects and its discrete financial information and operating results are regularly reviewed by the CODM in order to make decisions about resource allocation and assess performance. The data processing segment provides data analytics, geophysical modeling and artificial intelligence services for the mineral, oil & gas and water exploration industries. The energy storage segment develops, manufactures and installs vanadium flow batteries for grid-scale energy storage. Segment information for the periods presented is as follows:
