In a large saucepan, combine water and sugar over medium-high heat, stirring until sugar dissolves. Add strawberries, and bring to simmer. Reduce heat to medium, and cook for 15 minutes. Remove from heat, and add mint.

Cover, and steep for 10 minutes. Strain syrup, discarding solids. Store in the refrigerator in an airtight container for up to 2 weeks.
