Ore body information

  • General form TABULAR

Controls for ore emplacement

  • Conglomerate bed between amygdaloid basalt flows.

Comments on the geologic information

  • CALUMET AND HECLA CONGLOMERATE CAN BE TRACED FOR A DISTANCE OF MORE THAN 40 MILES. FOR MOST OF ITS LENGTH IT IS VERY THIN (1' TO A FEW FEET). IN CALUMET AREA, IT AVERAGES MORE THAN 10 FEET THICK. KEARSARGE WAS ONE OF THE RICHEST LODES - ESPECIALLY NEAR HANGING WALL. LODE AVERAGES 6-13 FEET THICK IN AREA OF MINING ACTIVITY. COPPER GRADE IN THE PRODUCTIVE PART OF THE KEARSARGE LODE APPEARS TO HAVE BEEN AS RICH AT OR VERY NEAR THE OUTCROP AS AT GREATER DEPTH, BUT THE REMAINDER OF THE LODE WAS RELATIVELY POOR AT THE SURFACE. AREAS OF LOW GRADE ORE NEAR THE SURFACE ARE COINCIDENT WITH AREAS OF RELATIVELY THIN OR CELLULAR, IMPERMEABLE LODE ROCKS.

Comments on the production information

  • 216,527 MT TOTAL PRODUCTION FROM ALL LODES. 5,739 MT FROM CALUMET HECLA CONGLOMERATE AT THE OSCEOLA MINE. 5,626 MT PRODUCED FROM CALUMET AND HECLA CONGLOMERATE FROM TAMARACK JR. MINE. 66,391 MT PRODUCED FROM KEARSARGE AMYGDALOID FROM NORTH KEARSARGE MINE. 52,233 MT PRODUCED FROM KEARSARGE AMYGDALOID FROM SOUTH KEARSARGE MINE. 86,358 MT PRODUCED FROM OSCEOLA AMYGDALOID FROM OSCEOLA MINE.

Comments on the workings information

  • KEARSARGE WAS ONE OF THE RICHEST LODES - ESPECIALLY NEAR HANGING WALL. LODE AVERAGES 6-13 FEET THICK IN AREA OF MINING ACTIVITY. IN TOTAL, OSCEOLA AMYGDALOID HAS BEEN MINED FOR A STRIKE LENGTH OF ABOUT 4 MILES AND THROUGH INCLINED SHAFTS TO A DEPTH OF 4,500 FT (2,700 FT VERTICALLY).

General comments

Subject category Comment text
Deposit THE OUTCROP OF THE OSCEOLA LODE WAS RICHEST AT THE N END OF THE OSCEOLA WHERE THE ROCK WAS AS GOOD AS ANY FOUND AT DEPTH ON THE LODE. SOUTH OF THE ONE. 3 SHAFT IN THE OSCEOLA MINE, THE TOP LEVELS WERE POOR. THE GRADE WAS ALSO POOR IN THE NO. 6 SHAFT TO THE 25TH LEVEL AND FARTHER SOUTH TO A GREATER DEPTH.
