Gibson immediately began to improve and expand the operation. He enlarged the mill pond by putting a chain of piers across the river above an existing dam, and built more dams in order to improve the flow of logs to his sawmills. He also renovated the mills, outfitting them with double gang saws, and brought in experienced workers from Lepreau to run them. In the spring of 1863 the mills began sawing 3 inch planks, called deals, which were floated to a log boom at the mouth of the Nashwaak. They were then taken on lighters or rafts down the Saint John River to the port of Saint John, New Brunswick, and thence to the British or American markets. Eventually Gibson also shipped wood to South America, Australia, and the West Indies. At times his wood production accounted for more than half of the goods exported annually from the port of Saint John.
