Comments

Comment (Deposit): SOME RICH PODS OF ORE OCCUR. COARSE CINNABAR REPLACES VEIN CALCITE AT FAULT INTERSECTION. THE VEIN IS TERMINATED BY THE FAULT, WHICH COINCIDES WITH THE TUFF CONTACT, WHICH HAS LOCALIZED THE ORE. CINNABAR OCCURS AS FLECKS, STRINGERS, AND SMALL AGGREGATES IN CALCITE WITH VEINLETS OF CINNABAR EXTENDING INTO LIMESTONE WALLROCK. THE ONLY REALLY PRODUCTIVE ORE BODY WAS LOCALIZED IN THE CALCITE VEIN WHERE IT INTERSECTS THE OVERLYING VOLCANIC -ROCK. CINNABAR OCCURRED IN RICH PODS OR BUNCHES FORMING ORE OF- EXCEPTIONALLY HIGH GRADE, BUT LIMITED EXTENT. SOME WAS VERY C-OARSELY CRYSTALLINE, AND IF MINED IN 1980 WOULD BE SOLD AT PRE-MIUM PRICES TO THE ORIENTAL MARKET FOR MEDICINAL USE. AWAY FRO-M THE VEIN, A LITTLE ORE WAS MINED WHERE SCATTERED CINNABAR OC-CURRED DISSEMINATED IN LIMESTONE BENEATH THE VOLCANIC ROCK. SP-ARSE CINNABAR ALSO WAS SCATTERED THRU THE TUFF, AND WHILE NOT -OF ECONOMIC VALUE, IT INDICATES THE MINERALIZATION IS OF PLIOC-ENE OR LATER AGE.

Comment (Workings): (1943) WORKINGS, LAST OPERATED 1943.440-FT HAULAGE LEVEL THAT CONNECTS WITH AN INCLINED STOPE EXTENDING TO THE SURFACE ABOUT 100 FT ABOVE. OTHER SHORTER WORKINGS TAP THE SAME ORE SHOOT AT HIGHER LEVELS, AND WEST OF THE FURNACE SITE A SEPARATE ADIT WAS- DRIVEN 300 FT BUT FAILED TO FIND ANY ORE

Comment (Deposit): ON GQ - 820, SHOWN AS HILLSIDE MINE, SEE HILLSIDE MINE CRIB RECORD NO. M055269 ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT

Comment (Development): IT WAS FIRST DEVELOPED BY W. H. HARRIS IN 1924-1926 AND SOLD TO GEORGE S. CLACK IN 1927. IN 1928 MR. CLACK ORGANIZ-ED THE CINNABAR KING MINING CO WHICH OPERATED THE PROPERTY UNT-IL 1931, PRODUCING ABOUT 250 FLASKS OF MERCURY IN RETORTS AND -A 15-TON ROTARY FURNACE. IN 1940 THE GROUND WAS RELOCATED BY T-HE AMERICAN ALMADEN MINING CO, ALTHOUGH APPARENTLY NOT ABANDON-ED BY MR. CLACK, AND TITLE WAS ALSO CLAIMED BY THE CINNABAR CI-TY MINING CO FROM 1944-49. IN 1953, EARL SIMPSON OBTAINED A CL-EAR TITLE, AND, AS HE ALSO HELD THE NEARBY HILLSIDE MINE, BOTH- PROPERTIES WERE SUBSEQUENTLY OPERATED TOGETHER. THE ROTARY FU-RNACE AND RETORTS WERE ON THE CINNABAR CITY PROPERTY, BUT APPA-RENTLY AFTER 1953, MOST OF THE ORE CAME FROM THE HILLSIDE MINE- AND IS CREDITED IN THE RECORDS TO THAT PROPERTY. IN 1973-1975-, TANCOR INTERNATIONAL IS RECORDED AS DOING ASSESSMENT WORK ON- THE CINNABAR CITY CLAIMS.
