Some people areinclined to add largely to these figures for gold lostand unaccounted for, but a residence of seven yearsamong the miners of the Klondike convinces the pres-ent writer that such enlarged figures are mostly grossexaggerations and that the official estimates are quitehigh enough to account for every ounce of gold thathas come out of the country. Silver.—The production of silver has been confined,with the exception of a very small amount taken fromthe prospects in the Southern Yukon, to the quantityoccurring with the gold and extracted from it whenit is reduced to bullion. Copper—Copper occurs in the southern portion ofthe Yukon territory in a belt extending from near the. One of the oldest homes in Dawson, occupiedby J. B.

In the vicinity of Whitehorse the oreis in the form of sulphides and is found in more orless extensive contact veins along the contact, of lime-stone and acid intrusives. A large number of claimshave been staked, and from these some ore has beenshipped southward to the smelter on Vancouver island,lint the high cost of transportation and the consequentexcessive cost of labor and supplies has militated verystrongly against the successful operation of theseproperties. Near the international boundary line at the headwaters of the White river and its tributaries nativecopper is found in some abundance in the gravel alongthe stream, and in time the recovery of this coppermay prove to be a productive and su -ssfiil industry.
