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.

Comments

Comment (Commodity): Molybdenite Nearly Constant At 1-2%. Cu Content Increased From 1% At Surface To 6-8% At 800 Ft Then Decreased To 2% At Bottom Of Mine. Bornite, Tennantite Important At Depth. Molybdenite Confined To Open Spaces. Bulk Of Chalcopyrite Is Interstitial To Breccia Fragments. Au, Ag, As, Sb, And Bi Were From Treatment Of The Copper Conc.

Comment (Development): Two Ore Bodies Developed, The Alamo And South Ore Bodies

Comment (Deposit): South Ore Body 220 X 100 Ft, Alamo Ore Body 270 X 150 Ft. Pipes Probably Join At 700 Ft And Pinch Out At 800 Ft.

Comment (Workings): 2 Adits, 5 Levels Below Haulage Level. Most Workings Now Inaccessible. 2 Compartment Winze. 2 Large Glory Holes On Surface

Comment (Geology): Molybdenite, The Latest Sulfide, Is Later Than Many Gangue Minerals. Breccia Pipe May Have A Zoned Sulfide Mineralogy

Comment (Location): Info From Land.St :1979

Comment (Development): Mine Operated Intermittently Between 1908-1919. Previously Owned By Ranchers Exploration And Development Co. (1976). Mining From 1973-1981 Was In-Situ Leaching.

Comment (Geology): Breccia Pipe Contains Angular To Subangular Blocks Of Volcanic Rocks Ranging From Several Inches To 4 Feet. Biotite Latite Porphyry Intrudes Breccia. Contact Of Breccia And Wallrock Is Irregular, Steeply Di Pping And Fractured. Pipe Divides Into 4 Smaller Pipes On Upper Level

Comment (Deposit): 5-97:Drilling And Grade Modeling Are Continuing On The Property And The Cu Resource Is 3 Billion Lbs. Grade Ranges From .8 To 1%. Amt Will Complete A Feasibility Study By 2-98 To Earn A 50% Undivided Working Interest From Bhp. Amt Is Earning A 51% Working Interest From Phelps Dodge By Spending $3.5 Mill On Exploration Over A 4 Year Period. Currently, Amt Controls 1800 Acres And Has The Right To Earn-In To An Additional 2200 Acres In Separate Agreements With Bhp And Phelps Dodge.

Comment (Ownership): 5-97:Drilling And Grade Modeling Are Continuing On The Property And The Cu Resource Is 3 Billion Lbs. Grade Ranges From .8 To 1%. Amt Will Complete A Feasibility Study By 2-98 To Earn A 50% Undivided Working Interest From Bhp. Amt Is Earning A 51% Working Interest From Phelps Dodge By Spending $3.5 Mill On Exploration Over A 4 Year Period. Currently, Amt Controls 1800 Acres And Has The Right To Earn-In To An Additional 2200 Acres In Separate Agreements With Bhp And Phelps Dodge. As Of 1996, Amt International Mining Corp. Seems To Own The Project, But This Has Not Been Confirmed. Amt Controls 1800 Acres & Has Right To Earn-In On An Additional 2200 Acres In Separate Agreements With Bhp & Phelps Dodge As Of May, 1997.

Comment (Reserve-Resource): American Eagle Reserves Stated In A Dec. 1996 Press Release Are 76.6 Million Tons Of 0.8 Percent Copper (Drill Indicated)

Comment (Commodity): Chalcopyrite Is Only Hypogene Mineral. Pyrite Filmed By Chalcocite ; Cu Sulfates On Walls Of Underground Workings. A Flat-Lying Lens 200 Ft Below Surface Yielded Several Thousand Tons Of Almost Pure Chalcopy Rite.

Comment (Geology): Copper Prince Breccia Pipe Produced Only In 1937 Although Prospected In 1907-1909. Breccia Fragments Range From A Few To Several Feet, Many Have Unde Rgone Only Slight Displacement From Original Position. On Adit Level Pipe Is Elliptical In Plan 280 X 150 Ft

Comment (Geology): The Copper Creek area can be viewed as several deposits - Old Reliable and Holly zones breccia fill deposit, the American Eagle and Keel zones porphyry deposit, which are beneath the Mammoth breccia deposit.
