Select a shallow, nonreactive dish, just large enough to hold the goat chops in a single layer. Add the orange juice, wine, oil, vinegar, orange zest, rosemary and ½ tsp salt to the dish and stir well.
Add the goat chops. Turn to coat both sides with the marinade. Cover and let stand for at least 30 minutes.
Remove the chops from the marinade and grill directly over the heat or coals, turning once until they are nicely charred and done to your liking. About 4-5 minutes per side for medium rare.
Let the goat chops rest for about 3-5 minutes before serving.
