Land Status

Land ownership: BLM Administrative Area
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Geology): LABOR RECORD DATA BASE ON MINE AND RECOVERY PLANT AT FULL CAPACITY AND AT 240 OP DAYS/YR THE APEX ORE BODY IS AN IRREGULAR-SHAPED CHIMNEY-LIKE DEPOSIT CONTAINED WITHIN A SOLUTION COLLASPE BRECCIA THAT FORMED BY THE COLLASPE OF OVERLYING SEDIMENTARY ROCKS INTO SOLUTION CAVERNS WITHIN THE MISSISSIPIAN REDWALL LIMESTONE. THE GA & GE METALS ARE CONTAINED IN THE JAROSITE AND GOETHITE RESPECTIVELY. THE BRECCIA ZONE CONTAINS NUMEROUS OXIDE, SULFATE AND CARBONATE MINERALS FORMED BY OXIDATION AND SUPERGENE ENRICHMENT.

Comment (Ownership): HECLA MINING CO. PURCHASED PROPERTY IN MARCH 1989 FROM MUSTO EXPLORATION LTD (VANCOUVER, BC) FOR $5.5 MILLION).

Comment (Production): HECLA MINING CO. PURCHASED PROPERTY IN MARCH 1989 FROM MUSTO EXPLORATION LTD (VANCOUVER, BC) FOR $5.5 MILLION). PRODUCT RECS A, D, G: GA METAL PRODUCED 50% 4N PURE (99.99%) AND 50% 6N PURE (99.9999%) PRODUCT C, F, I: COPPER CEMENT CONTAINS 12% AS - HANDLED BY COMMODITY BROKER - AND SENT TO SMELTER IN SPAIN. AG AND ZINC NOT RECOVERED - SENT TO TAILS.

Comment (Reserve-Resource): M1C1=R1. M2C1=R2. M3C1=R3. M9C4=M1C1. M9C5=M2C1. M9C6=M3C1. THIS QUANT MATRIX REPRESENTS ORE RESERVES BELOW THE 5434-FT LEVEL. THIS QUANT MATRIX REPRESENTS STOCKPILED DUMP ORE THAT IS BEING BLENDED WITH MINED ORE AT RECOVERY PLANT. THIS QUANT MATRIX REPRESENTS LOW-GRADE ORE RESERVES LOCATED ABOVE 5434-FT LEVEL. REPORTED IN 1986 ANN REPT AS IND. BUT MINE MGR STATED RESERVE AS ACTUALLY PROVEN. THIS RESERVE TOO LOW GRADE AND TOO DIFFICULT TO MINE AT PRESENT

Comment (Geology): ADDITIONAL MINERALS NOT CODED FORTHIS MINE ARE HYDROZINCITE.
