Mcintosh mine Except for some prospecting and assessment work there weret no other copper develop ments on Prince William Sound. In the Kotsina Chitina district some work was done on number of cop per properties, but the only produc- tive mining was that at the Kenne- colt group of mines. Some new de- posits of copper orc were discovered in 1920 in the region tributary to the government railroad. but there were no important developments.
 MISCELLANEOUS METALS
 In 1920 Alaska mines produced about 887 000 ounces of silver; in 1919, 488,034 ounces. The lead pro- duction increased from 564 tons in 1919 to about 880 tons in 1920 The in creased output of silver was largely won from the copper ores, but this increase like the increase in the pro- duction of lead, was in part won from galena ores mined in a small way at several localities. The largest ship ment of galena ore was made by a small mine in the Kantishna district.
 About 31 tons of stream tin con- centrates were mined in Alaska in 1920, compared with 86 tons in 1919. Most of this tin was mined in the York district, at the west end of Sew ard peninsula, where one dredge and several small operators were work ing on placer tin deposits. Several tons of stream tin were also recovered from gold-placer mining operations in the Hot Springs and Ruby districts, but this was not shipped. A total of 35 tons of stream tin was shipped from Alaska in 1920, but consider able part of this was mined in pre- vious years.
 The gold placers of the southeastern part of Seward peninsula, from the Chistochia (Slate creek) district. and from some other districts, continued to yield some platinum in 1920. The Salt Chuck lode mine, in the Ketchi- kan district, also continued to pro- duce platinum and palladium, as we'll as copper, In 1920.
 Work was continued at the Parks quicksilver mine, on lower Kusko- kwim river, in 1920, and some cin- nabar ore was produced. A small shipment of cinnabar ore was also made prospect in the same district.
 In addition to the prospecting of high grade coal in the Matanuska coal field by the navy department, noted above, coal mining was continued in this field by the Alaskan engineering commission on about the same scale as in previous years, to obtain fuel for the railroad and the nearby towns. Much underground work was done by the Boring Coal Company in the western part of the Boring river field, but no coal was produced except for use at the mine. The Alaska Coal & Petroleum Company also continued underground explorations in the east ern part of the field.
 The completion of the railroad be- tween Fairbanks and Healy creek (eXcept for the Panama river bridgel early in 1920 made the Nenana coal accessible, but the temporary bridge at Nenana river was washed out by a flood, and the coal was carried across the river by aerial tram During 1920, coal was mined in the Nenana field at the Burns and Calderhead mines, operated under temporary permits. A lease was granted to the Healy River Coal Mining Co.,, in the same field. Lignitic coal was also mined on a small scale in the Cook Inlet region and in other parts of Alaska. A coal land lease was granted in the Cook Inlet field. The coal production in 1920 was about 6S,OOO tons; that in 1919 was COSTA tons.
 The Chilkat Oil Go. continues to produce and refine petroleum in the Katalla field and brought in two new wells.
