Kaffo Valley Project

The Kaffo Valley project is situated in Doguwa LGA in the south of Kano State, located just seven kilometres from the nearest good-quality tarred road and existing mining infrastructure at Ririwai, which is a former tin mining community. Much of the tin mining was done from alluvial sources although extensive underground development was also made on in-situ poly-mineralic veins containing tin, tungsten, copper and other metals. This mineralization may also be considered for further re-evaluation and development in the future.

EcoPhoenix and CSA Global consider the Kaffo Valley deposit to be of potentially huge economic significance. The minerals of interest are pyrochlore (containing niobium and uranium) and cryolite. These minerals are contained as accessory constituents throughout unusual, highly-sodic, albite-arfvedsonite granite. The granite body is roughly circular with a diameter of just over one kilometre. This granite is part of a larger area of volcanic and sub-volcanic rocks forming the Ririwai ring complex that is one of the ‘younger granites’ of Jurassic age that occur in parts of Kaduna, Plateau, Kano and Bauchi States.

Statistical and geological analysis of British Geological Survey data6 predicts that 47mt of high grade ore exists at Kaffo Valley. This would support at least a 20 year mine life at 2mtpa. Given that the predicted high grade zone can be delineated and improvements on recovery using modern metallurgical methods are possible, then CSA Global have demonstrated that a theoretical NPV of US$776 million* is possible for a 20 year mine at 2mtpa⁷.
