A weatherized mineral mixture is produced by heating a digestible fat or fatty acid and spraying a mineral mixture with the heated digestible fatty acid to form a protective layer over the mineral mixture. The weatherized mineral mixture may be free of salts of fatty acids, namely soaps. The weatherized mineral mixture sheds water and is wind-resistant. Upon ingestion by livestock animals, the protective coating is digested and the minerals within the mineral mixture are absorbed by the livestock animal.
