Ministry of Mining (Kenya) - Wikipedia

Kenya has no significant mineral endowment. The mining and quarrying sector makes a negligible contribution to the economy, accounting for less than 1 percent of gross domestic product, the majority contributed by the soda ash operation at Lake Magadi in south-central Kenya. Thanks largely to rising soda ash output, Kenya's mineral production in 2005 reached more than 1 million tons.
