All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

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 (Reserve-Resource): AVERAGE IRON CONTENT OF 428 FT OF DRILL CORE WAS 37.82% WHICH IS CLOSE TO AVERAGE CONTENT OF ORE", 1,849,000 TONS AVERAGING 39.5% FE OR 4,680,000 TONS AVERAGING 37.82% FE.

Comment (Workings): NUMEROUS OPEN PITS

Comment (Geology): QUARTZ DIORITE CONSISTS OF FINE-TO COARSE-GRAINED VARIETIES, NEAR THE CONTACT WITH THE QUARTZ DIORITE THE MCCLOUD LIMESTONE IS EXTENSIVELY METAMORPHOSED TO COARSELY-CRYSTALLINE NEARLY-WHITE MARBLE; OCCASIONAL CHERT LENSES AND NODULES HAVE BEEN RECRYSTALLIZED TO GRANULAR QUARTZ. DIKES OF FINE-GRAINED DIORITE, DIABASE, ANDESITE AND APLITE CUT THE OTHER ROCK TYPES. EVENDENCE OF FAULTING IS ABUNDANT IN THE SOUTHWESTERN MOST OF THE OPEN PITS.

Comment (Deposit): SHASTA IRON COMPANY OWNS 178 ACRES OF PATENTED LAND AND SIX UNPATENTED. CALIFORNIA CONSOLIDATED OWNS 88.6 ACRES OF PATENTED LAND ADJOING AND WEST OF THE SHASTA IRON COMPANY.

Comment (Production): TWO HUNDRED TONS OF FE ORE MINED IN 1894 PROBABLY CAME FROM THIS PROPERTY

Comment (Deposit): IRREGULAR LENSES OF MASNETITE INTERCALATED BETWEEN SKARN AND IN SOME PLACES INTIMATELY MIXED WITH IT.

Comment (Reserve-Resource): IRONEX COMPANIES CORE-DRILLING PROGRAM BLOCKED OUT THE RESERVES, PRODUCTION WAS SCHEDULED AT A RATE OF 700,000 TONS ANNUALLY FOR FIRST 5 YEARS AND 500,000 TONS FOR THE NEXT 10 YEARS. NEW DISCOVERIES OF IRON ORE IN AUSTRALIA MADE THE IRONEX PROPOSAL ECONOMICALLY UNATTRACTIVE.

Comment (Commodity): ORE CHIEFLY IS MAGNETITE, MUCH BEING LODESTONE, ABUNDANT HEMIATITE AND GEOTHITE AND SUBORDINATE SPECULARITE

Comment (Location): SINCE THE BUILDING OF THE SHASTA DAM, THESE DEPOSITS CAN ONLY BE REACHED BY BARGE OR BOAT: UTM ACCT LAND STATUS VALUE CALCULATED 7-94 USING GIS OVERLAY ANALYSIS WITH USFS LAND OWNERSHIP BOUNDARIES, 1:126,720 SCALE.
