Peel and chop the mango. In a blender, blend the mango until it's smooth to make a mango purée.
In a pitcher, muddle the mint leaves along with sugar and lime juice. This will release the aroma and flavor of the mint leaves.
Add the mango purée, rum, and club soda to the pitcher. Stir it all together till it's well combined. Fill glasses with ice and pour the mango mojito over it. Garnish with a lime wheel and mint sprig.
