Yes, you want to work the gold as much as possible since it contributes close to half of your commerce. But on the flip side it slows down your capital's growth (so cannot afford losing population through slavery), and it's not a great tile to produce settlers / workers with (only contributes 3 production - 2 food = +1, compared to +2 for a regular mine). That leaves forest chops as the main way to hasten your early expansion.
