Hi, what u think its the faster money maker? coal or gold mining? can’t decide between those 2
Think you can get about 300 coal/hour at mining guild.
Not sure how many gold you can get at Karamja.
But if you’ve done Shiloh you can mine them. Walk to the cart. Bank (buy vials of stock is full) and repeat.
Coal mining at the coal carts would be your best gp p/h, you’ll need 58 combat to not agro the bats though.
if not, mining guild, and if not there, ardy east mine.
Gold is fairly profitable, however I would be inclined to think coal would be more profitable.
I’m thinking Gold; everyone mines Coal (I know 3 major spots), but I’m only aware of that one Gold spot mapped above and can’t imagine there’s many Gold miners 
Coal’s probably more useful though.
at 50 mining, brimhaven gold spot is an inventory every 6-7 minutes return trip. 9-10 trips an hour. 234-260 gold an hour. x 800gp = 187,200 - 208,800gp minus ardy tele runes
