Porphyry copper deposits are large mineral systems formed by mineral-rich fluids associated with intrusive rocks deep beneath the Earth's surface. They are among the world's most important sources of copper and can also contain significant gold and molybdenum, making them highly attractive exploration targets due to their scale and long-term development potential.

Copper is a critical metal used in electricity transmission, renewable energy, electric vehicles and modern infrastructure. As global demand continues to grow alongside the energy transition, new copper discoveries will play an increasingly important role in meeting future supply needs.

Porphyry copper deposits are valued for their potential to host large, long-life mineral resources that can support mining operations for decades. While they typically have lower grades than vein-hosted deposits, their size and scale can make them among the most economically significant mineral deposits in the world.

Tahami Center represents a distinct exploration opportunity within Quimbaya’s Tahami Project, targeting a district-scale copper-molybdenum-gold porphyry system. Supported by geological mapping, geochemistry, geophysics and active drilling, the project complements the Company's high-grade gold-silver vein exploration at Tahami South and broadens Quimbaya's discovery potential.

Quimbaya is advancing a systematic exploration program designed to evaluate the size, geometry and mineral potential of the Tahami Center porphyry system. Through geological mapping, surface sampling, geophysical surveys and diamond drilling, the Company is testing multiple priority targets to better understand the extent of the mineralized system and identify areas with the greatest discovery potential.

Although both projects form part of the broader Tahami Project, they target two different mineral systems. Tahami South is focused on high-grade gold and silver vein mineralization, while Tahami Center is exploring a large copper-molybdenum-gold porphyry system, providing Quimbaya with two complementary exploration opportunities within the same district.
