context_page_description: Orex Exploration is a former Canadian gold mining company that conducted exploration work on mining properties it owned in the Goldboro and Guysborough County areas of Nova Scotia. The properties owned by Orex were the sites of the former Boston Richardson Mine, Dolliver Mountain Mine, West Goldbrook Mine, and East Goldbrook Mine which operated between 1892 and 1912. Headquartered in Rouyn-Noranda, Quebec, the company was founded in 1987 and raised funds for exploration work, in part, by issuing stocks traded on the Montreal Stock Exchange and then the TSX Venture Exchange. It became a subsidiary of Anaconda Mining Inc. after Anaconda acquired the company in a stock swap deal in 2017.
context_section_description: In 1861 gold was discovered in quartz veins on the Isaac's Harbour anticline.  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.
  In 1896 the mine was operating at full capacity and by 1897 three shafts gave access to the ore at a depth of 60m.  By 1900 the main shaft was 160 metres (520 ft) deep and selective mining methods were being used and two Wilfley Concentrators were in operation.  Two additional concentrators were installed in 1901.  In 1902 another shaft was sunk which became known as the Boston Richardson Shaft, and which is still in existence to the present day.
  The Boston Richardson Mining Company took over the property in 1903 and resumed work on the Boston Richardson shaft which they extended to a depth of 122m which by 1905.  A bromo-cyanide plant was built on the property in 1906 and gold recovery went up to 70%. The main shaft had reached a depth of 213m by 1902. Operations were stopped on August 15, 1908 because of financial difficulties. In 1909 the New England Mining Company took over operations until 1912.
  In 1926 the Metals Mining and Smelting Corporation of Canada acquired the property and attempted to recover gold from the old mine tailings.
