In a large pitcher, stir together frozen margarita mixer, 1 can (10 ounces) of water, tequila, orange liqueur, lime zest and salt. Stir until margarita mixer is dissolved.
Pour into ice pop mold and cover. Freeze for 2 to 3 hours. Gently insert wooden sticks, keeping as upright as possible. Freeze at least another 4 hours or overnight.
Remove cover. Run outside of mold under warm water and gently pry pops from mold.
Place in freezer-safe resealable plastic bag and store in freezer until serving.
For nonalcoholic pops replace tequila with 1/4 cup water and orange liqueur with 2 tablespoons orange juice.
