of the 4 resources, bottom left is found in the chromite mine. top right is made in a level 5 foundry from coal (found in the chromite mine), iron ore (found in the iron mine), and nickel ore (found in the Chromite mine). top left is made from cypress wood. without the boat to take you to the cypress swale location, you can't chop this down anywhere. look to daily task rewards and traders in Silverton to find it. and the bottom right parts are a multi step situation. first you have to complete the main storyline to the point involving the brotherhood to unlock the trader in Silverton who will trade you 3 specific things every day for gold nuggets. 3 gold nuggets buy one boat parts from the McCoy who sets up his wagon to trade beside the pop up trader, usually 40 minutes once a day somewhere in the main area of the map. so in theory, it will take a minimum of 50 days to get all 50 boat parts because you can only earn 3 gold per day and thus one boat parts per day via trading.
