What type of colony was Jamestown?

The Jamestown colony was a financial venture by a group of private investors in a London firm called the Virginia Company. The group obtained a royal charter from James I in 1606, hence the name Jamestown, and hoped to profit from mining silver and gold and locating and establishing river routes to the Pacific Ocean that could be used for trade with the Eastern world.
Mismanagement and bad luck plagued the colony from its inception in 1607. Illness, hunger, and Native American hostilities pushed the colony to near collapse over several of its early years. However, the marriage of colonist John Rolfe to Pocahontas helped improve relations with indigenous people for a time, and as Jamestown revolutionized its tobacco growing enterprise, the colony began to thrive by 1619.
