Canadian-based Navasota Resources Limited – a Torontolisted mineral exploration company engaged in the evaluation and development of resource properties, mainly in West Africa – has started drilling on the AMIG bauxite project in north-western Guinea.
The company holds the right to earn a 100% interest in the AMIG permit, which covers 1 064 squ kms in the prefectures of Telemele and Gaoual. Proposed and existing infrastructure includes refinery construction and hydro-electric development.
Navasota has retained RSG Global Consulting of Perth to manage the programme, and has contracted West African Drilling Services to conduct air-core drill testing of the bauxite plateaus.
During a recent site visit RSG collected seven grab samples, six of which returned bauxite grades of between 40% and 55% Al203.
RSG has recommended a first-pass, air-core drilling programme at 300 to 600m spacing over plateaus identified by a spectral and topographic analysis of Aster satellite imagery. That study has ranked various targets based on interpreted geo-morphology, with residual bauxite plateaus ranking highest. Drilling will consist of shallow holes 10 to 20m in depth, with samples collected at 1m intervals down-hole and logged.
The mineral exploration permits are situated in the worldclass Boke Bauxite Belt in north-western Guinea, which hosts the world’s largest and best quality bauxite deposits with grades of between 40 and 60% of aluminium oxide. The permit area is located in what has been termed “a very good neighbourhood”, surrounded by several of the main players in international bauxite mining.
The Republic of Guinea hosts more than 30% of the world’s current bauxite reserves, and boasts among the richest deposits in the world. As a result the major bauxite miners – among them Alcoa, Alcan, Global Alumina and Rusal – are actively developing mines in Guinea. Moreover, there are proposals for the construction of three refineries in the country over the next five to ten years.
