Goldboro is a Canadian rural community in Guysborough County, Nova Scotia. Located on the Eastern Shore along Route 316, Goldboro is approximately 16 kilometres west of the shire town of Guysborough. In 1861 gold was discovered in quartz veins on the Isaac's Harbour anticline to the east of the community. In 1892, Howard Richardson was the first to note gold within shale and quartz veins which became generally known as the Boston Richardson Belt. Mining on the property began in 1892 when the Richardson Gold Mining Company started developing the belt and continued until 1912.
