Geologic structures

Type of structure Regional
Structure description Sediments Of The Anarchist Group Were Deposited Along An Active Continental Margin.

Controls for ore emplacement

  • Seven Quartz Veins Were Mined. The Ivanhoe Vein Is 3.5-4.5 Feet Thick And Strikes North-Northwest And Dips 60w. Silver Ore Was Richer Near The Surface; Veins Intersected At A Depth Of 1560 Ft Had Average Ag Content Of Less Than 1 Oz/Ton (Umpleby, 1911).

Comments on the geologic information

  • THE VEIN IS IN PHYLLITE AND ARGILLITE OF THE PERMIAN BULLFROG MOUNTAIN FORMATION OF THE ANARCHIST GROUP.

Comments on the production information

  • HAND-SORTED, NEAR-SURFACE ORES MINED BETWEEN 1888 AND 1897 CONTAINED AS MUCH AS 1000 OZ/TON AG AND SEVERAL OUNCES OF AU. APPROXIMATELY 1000 TONS OF ORE WAS SHIPPED TO SMELTERS IN WASHINGTON AND MONTANA; SEVERAL SHIPMENTS AVERAGED 392 OZ/TON AG AND 1.2 OZ/TON AU (MOEN, 1976, P. 123; RINEHART AND FOX, 1972, P. 91).

Subject category Comment text
Deposit THE IVANHOE VEIN WAS DEVELOPED BY SEVERAL SHALLOW SHAFTS, ONE OF WHICH WAS LATER SUNK TO A DEPTH OF 500 FT. THE RICHEST ORES WERE NEAR THE SURFACE; THESE WERE MINED BY STRIPPING THE HANGING WALL OF THE VEIN OVER AN AREA 70 BY 120 FEET. IN ABOUT 1914, A 4400-FT CROSSCUT WAS DRIVEN FROM THE WEST SLOPE OF PALMER MTN IN AN ATTEMPT TO INTERSECT THE VEIN AT A DEPTH OF 1560 FT (UMPLEBY, 1911). ; INFO.SRC : 1 PUB LIT
