Place the mint leaves and rum in an old-fashioned glass and set aside for 5 minutes. Using a muddler or the back of a tablespoon, bruise the mint leaves with the rum. Add the Agave In The Raw® and mango nectar to the rum. Squeeze the lime into the glass, then add the squeezed wedge. Add 4 ice cubes. Pour in the soda and stir just enough to blend. Garnish with the mint sprig and serve.
