The Canadian-based Kansai Mining Corporation is undertaking exploration for gold in Kenya and reports encouraging results from its drilling at the Migori gold project.

This project covers 310.5 km2 of the Migori greenstone belt within the Migori district, Nyanza region in south-western Kenya, on the eastern shores of Lake Victoria. The project is situated 290 km west of Nairobi parallel to the Tanzanian border and Migori is eight hours drive from Kenya’s capital, Nairobi.

Kansai’s Migori concessions cover a greenstone belt of 68 km in length, which is one of ten in the area. Eight of the other greenstone belts are south of the border in Tanzania, which has seen dramatic growth in gold exploration and exploitation in recent years. Historically the area has seen various mining operations.

Gold mining by Europeans in the Migori area began in the 1910s and continued into the 1930s. By the mid-1930s Falcon Bridge Africa had discovered the Macalder copper, zinc, gold, silver mine in the northern part of the concession. This deposit was mined until the early 1960s when all the easily accessible ore was exhausted and for six years the initially alluvial Nyanza gold mine was exploited, which produced more than 100,000 oz of gold, finally closing in 1968.

Kansai’s recent drilling results include visible gold in some samples, with four of five holes drilled relating to the Kakula-Kalange-Munyu mineralised zone, which has a strike length of approximately three kilometres. The fifth hole was drilled at the Nyanza mineralised zone.
