About Koryx Copper Inc.

Koryx is a Canadian copper development company focused on advancing the 100-per-cent-owned, preliminary-economic-assessment-stage Haib copper project in Namibia whilst also building a portfolio of copper exploration licences in Zambia.

Haib is a large and advanced copper/molybdenum porphyry deposit in southern Namibia with a long history of exploration and project development by multiple operators. Mineralization at Haib is typical of a porphyry copper deposit, and the deposit remains intact. Porphyry copper deposits are a major global source of copper with examples being concentrated around the Pacific Rim, North America and South America. Haib is one of the few examples of a Paleoproterozoic porphyry copper deposit in the world and one of only two in southern Africa (both in Namibia). Due to its age, the deposit has been subjected to multiple metamorphic and deformation events, but still retains many of the classic mineralization and alteration features typical of these deposits. The mineralization is dominantly chalcopyrite with minor bornite and chalcocite present and only minor secondary copper minerals at surface due to the arid environment.

More than 70,000 metres of drilling has been conducted at Haib since the 1970s with significant exploration programs led by companies including Falconbridge (1964), Rio Tinto (1975) and Teck (2014). Teck remains a strategic and supportive shareholder. In addition to extensive drilling, metallurgical testing, geophysics and geological mapping, various mine modelling and technical studies have been completed to date.
