  • MAJOR TACTITE OREBODIES LOCALIZED BY ABRUPT BENDS IN GRANODIORITE/LIMESTONE CONTACT LOCALLY, ABUNDANT SCHEELITE IN QUARTZ VEINS WHICH CUT TACTITE OF NE. PIT. LARGE TACTITE OREBODIES WERE PENDANT LIKE MASSES OF REPLACED LIMESTONE PROTRUDING DOWNWARD INTO GRANODIORITE.

Comments on development

  • ACQUIRED BY GETCHELL IN 1942, MINED 1942-43, 1952-1953. DURING THE 1942-43 PRODUCTION PERIOD, GETCHELL FIRST MINED THE DEPOSIT BY TWO GLORY HOLES FROM AN ADIT 315 FT LO-NG. THE GLORY HOLES WERE SUBSEQUENTLY CONNECTED TO FORM A SING-LE OPEN PIT FROM WHICH ORE WAS LOADED BY POWER SHOVEL INTO TRU-CKS. MINING IN 1952-3 WAS FROM OPEN PITS.

Deposit PROPERTY WAS KNOWN AS EARLY AS 1917; WAS ACQUIRED BY GETCHELL IN 1942 AND MINED TILL SUMMER, 1943. MINING RESUMED IN 1952 AND CONTINUED UNTIL 1953, BY OPEN-PIT METHODS. FAYANI AND BLAINE HELD THE CLAIMS IN 1917, THEY WERE RELOCATED LATER BY KIRBY, AND SOLD TO GETCHELL MINE INC., IN 1942. WORKINGS CONSISTED OF 3 OPEN PITS IN 1957, AS WELL AS SHORT AIDITS AND TRENCHES. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
Deposit KIRBY OREBODY IS A TABULAR MASS OF TACTITE ON CONTACT OF OSGOOD GRANODIORITE AND PREBLE LIMESTONE. TACTITE BODY NE-ARLY PARALLELS THE HILLSLOPE, CAPPED BY A THIN LIMESTONE LAYER-. OUTCROPS ARE BROAD, BUT TACTITE IS ACTUALLY THIN, LESS THAN -60 FT BELOW SURFACE. LIMESTONE IS COMPLEXLY FOLDED AND TACTITE-PODS ARE VERY IRREGULAR LARGE MASSES OF ENDOSKARN FORMED IN GR-ANODIORITE, WITH SOME CU OXIDE STAINING. THE DEPOSIT ENDS DOWN-WARD TO THE EAST AGAINST A LOBE OF GRANODIORITE THAT CUTS ACRO-SS THE LIMESTONE BEDS. THE HAULAGE ADIT, 80 FT BENEATH THE LOW-EST OUTCROP, IS ENTIRELY IN GRANODIORITE. OTHER BODIES OF SCHE-ELITE-BEARING TACTITE OCCUR NE OF THE MINE WHERE THE CREEK CRO-SSES THE CONTACT ZONE, BUT THE TUNGSTEN CONTENT IS ONLY ABOUT -0.2 % WO3. ROCK AT THE LOWER KIRBY PIT (NEAR CREEK) DISPLAY SW-IRLS OF BIOTITE BOOKS NEAR CONTACT.
