Preheat oven to 250° F. Combine rice, oats, almonds, and coconut in a large bowl. In a separate bowl combine brown sugar, maple syrup and oil. Combine both mixtures and stir well. Line a cookie sheet with non-stick foil and spread rice mixture evenly. Bake 1 hour, stirring occasionally. Remove from oven and transfer to a large bowl. Add raisins and mix to distribute evenly. Cool and store in an air-tight container.
