Comments on the location information

  • Tiger and Poorman shafts now filled with waste rock. Poorman mill and Tiger mill burned down in 1896, and were replaced by the Tiger-Poorman mill (no longer extant) on the site of the old Tiger mill.

  • Name Tiger-Poorman
    General form PINCH AND SWELL
    Strike N 60 DEG W

    Depth to bottom 457.2M

Comments on the ore body information

  • The Tiger-Poorman orebody, bounded on the east by the O'Neill Gulch reverse fault, (N-S 75E) and possibly by another N-S fault with a steep easterly dip to the west, consisted of 5 individual ore shoots, oriented in echelon, and offset by small faults. Between the 2000 and 2200 levels, when the vein passed into the Prichard Formation, the ore broke up into short, narrow shoots of low grade, too poor to mine profitably.

Controls for ore emplacement

Comments on the production information

  • Zinc, copper, and gold only recovered from small quantities of dump material worked in the 1940s and 1950s

Comments on the reserve resource information

  • Reserves exhausted when mine closed in 1908. Production since 1908 came from clean-up of underground workings and surface dumps by lessees. Hecla explored the western end of the 300 and 600 levels from the Tiger shaft in 1928 for a reported body of zinc-rich ore. Such ore would not have been mined before 1908 due to inability to handle the zinc. No such orebody was found. Possibilities for additional ore are restricted to the area west of the western boundary of the Tiger-Poorman orebody, although a modest amount of drifting found no ore in that direction.

  • Type of workings Underground
    Name of workings Poorman Shaft
    Overall depth 305M

Comments on the workings information

  • The Tiger Mine waa originally developed by four short adits, the Poorman by three short adits, each 100 feet long.

Comments on development

  • The Tiger lode was discovered by prospectors searching for placer gold on Canyon Creek. They found float of lead-silver ore and traced it to the vein. The Poorman was located the next day, the two claims covering almost all of the orebody. The Tiger and Poorman were operated independently, as the Tiger Mining Co. and the Coeur d'Alene Silver-Lead Mining Co., respectively, until consolidated as the Consolidated Tiger and Poorman Mining Co. in 10/1895. The mine(s) operated continuously from 1887, with several changes in ownership, until 10/1908, when the Federal M&S Co. permanantly closed the mine due to exhaustion of ore. Leasers operated the mine until 11/1920 when purchased by Hecla Mining Co. Hecla explored the west end of the 300 and 600 levels in 1928 for zinc-rich ore but found none. Some ore shipped from surface dumps in 1940s and 1950s. Shafts now filled with waste rock and surface plant removed. Workings are flooded and inaccessible.
