Jerry Doyle operated a lime kiln on Snapper Island, fired by wood from the nearby Daintreerainforest, ferried over on a vessel called the Nellie. The kiln was constructed in 1901 by the Mossman Central Mill Company, which signed a contract with Doyle to provide burnt lime, and he produced ʻample suppliesʼ of lime and fertiliser. Coral was probably obtained from the fringing reef on the south-western side of the island. The company opened a grinding plant to improve the quality of the coral lime, and Doyleʼs operation was still in progress in 1911, when the MCMC also entered into a contract for lime with the Chillagoe Railway and Mines Company. Subsequently, in 1914, coral mining was carried out by Ishimoto, who was paid £2 per ton by the MCMC to deliver coral lime to the old wharf on the Mossman River.
