Comments on the workings information

  • PITS AND AN ADIT.

Comments on development

  • THE DEPOSIT HAS BEEN EXPLORED BY A SERIES OF OPENCUTS AND AN ADIT CROSSCUT FROM WHICH A RAISE EXTENDS TO THE SURFACE. IN THE NO. 2 PIT AREA 100 FEET WEST OF NO. 1 PIT A DEPOSIT IS EXPOSED IN THREE OPENCUTS AND A 200-FOOT ZONE THAT WAS STRIPPED OF OVERBURDEN IN THE 1930'S AS PART OF THE WORK DONE BY THE WORKS PROGRESS ADMINISTRATION. WORK ON THE POLARIS CLAIM IN 1954 BY THE FEDERAL BUREAU OF MINES COMPRISED BUILDING 2,400 FEET OF BULLDOZER ACCESS ROADWAYS, EXCAVATING 470 FEET OF TRENCHES OR CUTS, EXTENSIVE STRIPPING AT THE SITE OF THE CAVED PORTAL, AND REMOVING ABOUT 14 TONS OF MANGANESE MATERIAL FROM NO. 1 PIT FOR METALLURGICAL TESTING AT THE BUREAU OF MINES LABORATORY AT ALBANY, OREG. THIS MATERIAL ASSAYED 24.6 PERCENT MN, 23.9 PERCENT SIO2, 19.6 PERCENT FE, 1.06 PERCENT A1203, AND 3.61 PERCENT CAO. SMELTING TESTS WERE UNSUCCESSFUL IN PRODUCING A SUITABLE FERROMANGANESE OR FE-MN-SI ALLOY. LOSSES IN THE SLAG WERE ALSO EXCESSIVE.

Deposit REMOVAL OF OVERBURDEN DISCLOSED A HIGHLY SILICEOUS MANGANIFEROUS ZONE 155 FEET IN LENGTH AND RANGING FROM 5 TO 20 FEET IN THICKNESS. THE ZONE APPEARS TO STRIKE N. 80 DEG W. AND DIP 30 DEG N. THE HANGING WALL IS ALTERED BASALT SIMILAR TO THAT IN NO. 1 PIT. THE FOOTWALL IS OBSCURED BY OVERBURDEN. AT THE WESTERN END OF NO. 2 PIT, THE MINERALIZED ZONE IS LIMITED BY AN OUTCROP OF BASALT; HOWEVER, THE ACTUAL CONTACT CANNOT BE OBSERVED BECAUSE OF OVERBURDEN. ON THE EASTERN END, THE ZONE APPEARS TO PINCH OUT. THE LOWER PART OR FOOTWALL SIDE OF THE MINERALIZED ZONE CONSISTS OF QUARTZ 15 TO 20 FEET THICK. THE UPPER PART OR HANGING-WALL SIDE IS MANGANIFEROUS AND IS 1 TO 5 FEET THICK. A SAMPLE OF THE SILICEOUS MATERIAL ASSAYED 1.4 PERCENT MN, LESS THAN 0.01 OUNCE AU, AND 0.02 OUNCE AG PER TON. SAMPLES FROM THE MANGANIFEROUS PART OF NO. 2 PIT ASSAYED 20 TO 30 PERCENT MN. IN THE NO. 1 PIT TRENCHING AND STRIPPING HAVE OUTLINED THE MINERALIZED ZONE FOR A LENGTH OF APPROXIMATELY 100 FEET. AN AVERAGE
Deposit WIDTH OF 20 FEET, AND A DEPTH OF 20 FEET OR MORE. THE ZONE APPEARS TO BE LOCALIZED ALONG A BASALT-RED LIMESTONE CONTACT, STRIKING EAST OR NORTHEAST AND DIPPING 45 DEG N. POOR CONTACT EXPOSURES MADE ACCURATE DETERMINATION OF THE STRIKE DIFFICULT.
Deposit A 165-FOOT CROSSCUT AND A 108-FOOT VERTICAL RAISE WERE DRIVEN YEARS AGO, APPARENTLY TO DETERMINE ANY DOWNWARD EXTENSIONS OF THE MINERALIZED ZONE. THE CROSSCUT IS NOW CAVED AT THE RAISE. NO MANGANESE MINERALIZATION WAS SEEN IN THE CROSSCUT, WHICH IS IN ALTERED BASALT. IF THE DEPOSIT DIPS NORTHWARD AS IS BELIEVED, THE CROSSCUT WOULD HAVE TO BE SUBSTANTIALLY LONGER TO INTERSECT THE DEPOSIT. ; INFO.SRC : 1 PUB LIT
