Tempestas Copper Inc (TCOP) is part of the Tempestas Group of Companies. Tempestas Copper Inc has its roots way back in the 1920s, when the Johnson family of Arizona founded the Zelleweger Mine, which was patented in 1924, and spent nearly 100 years managing their land - test-drilling and mining, extracting small amounts of copper and gold.

Leap forward to 2020 when the Johnson family and Tempestas Global Ltd got together to form Tempestas Copper Inc. The company now manages a far bigger Kelvin Project area of 226 claimed lodes, and one patented lode in Kelvin, Arizona, as well as other mining projects in Mexico and Chile.  

Tempestas Copper Inc is led by President and Chief Executive Officer, Andrew Paul, a 25-year veteran of major investment banks, along with Chief Operating Officer, Andrew Costain, and Andre Peterkin, Chief Strategy Officer.

In May 2025, Tempestas Copper Inc embarked on a major multi-million-dollar test-drill program to further confirm the location, volume, type and value of the in-ground copper at the Kelvin Project. With the drill program in full swing, and numerous Assays sent onto independent experts to ascertain the copper location and purity, the drill program aims for completion in 2027.

Tempestas Copper Inc’s parent company is Tempestas Global Ltd (TGLO). TGLO is a Family Office with more than 80 years of expertise and over $7 Billion in assets under management. Its business aim is to unlock the potential of copper assets by leveraging innovative financial strategies and mining practices. TGLO utilises its financial acumen to seek out critical minerals, currently in-ground, through their operational and strategic experience to locate and value copper assets, fund, develop and manage mining schemes to extract the minerals cost effectively and profitably.
