Experimental permafrost tunnel begun in 1959 in Tuto area in Greenland was extended to 605 ft during 1960 field season, and 3 rooms were excavated off main drift; modified conventional hard-rock mining methods and equipment, using drilling, blasting, mucking, and ventilating cycle, are described and evaluated; new building material was obtained from varying mixtures of fine-crushed rock, sand, clay, rock flour (silt) slurry, water and snow.
