  • General form AMYGDALOIDAL LODE

Comments on the geologic information

  • The Osceola amygdaloid throughout the area that has been extensively developed, and probably over a much larger area, has a distinctly rough or fragmental top. Its surface, which is much more irregular than that of the Kearsarge amygdaloid, consists of a series of hummocks and depressions of very irregular shape and variable size. Perhaps the tops of the hummocks and the bottoms of the depressions would average 12 to 15 feet above and below an average plane, or 25 to 30 feet from top of hummock to bottom of depression. In places the variation is considerably greater, and of course in other places it is less. The lode is distinctly of the fragmental type. There is less of the non-fragmental, cellular lode rock than in the Kearsarge amygdaloid but where present it commonly underlies the fragmental rock, as in the Kearsarge. The coarse cellular rock that is very common in the lower part of the Kearsarge lode is also less abundant in the Osceola. In many places the lode passes directly from fragmental lode to fine foot trap. There are areas where the lode is mainly of a rather thin cellular type. There are considerable areas of the lode that contain much sandy material and are of the "scoriaceous" type. In the Osceola amygdaloid lode, as in the Kearsarge, by far the richest and most uniformly mineralized portion lies against the hanging wall. The mineralized rock, however, extends irregularly downward, in places 50 feet or more from the hanging wall. No quantitative data are available as to the relative amount of copper at different depths in the lode, but the general impression is that the top 4 to 5 feet contains fully 75 to 80 per cent of the copper that is present in the upper 10 feet of lode and that the 1 foot just below the hanging wall is by far the richest part of the lode. The copper that lies deep in the lode is irregularly distributed. It is confined to the areas where the fragmental rock extends to considerable depths, but there is too little information a

Comments on development

  • Important production from the Osceola lode in the Osceola mine began in 1879 and continued without interruption for any whole year till 1920. Exploration on the Osceola lode by the Calumet & Hecla Co. began in 1895 and steady production in 1904. The Osceola amygdaloid lode was worked from the Osceola, Centennial, Tamarack, and Calumet & Hecla mines (Osceloa branch).
