NATIVE MICHIGAN COPPER by AL STIMAC
3
Native Copper One of the Few Metallic Elements to Occur in Uncombined Form as a Natural Mineral Occurs rarely as Isometric Cubic and Octahedral Crystals More Typically as Irregular Masses and Fracture Fillings
4
PERSPECTIVE Kennecott-Utah Copper Contains 0.5 to 0.8% Copper One 350 Ton Truck with O.6% Copper yields 3 Tons of Copper Michigan Copper is 2 to 100% Copper Depending on the Sample
5
KEWEENAW PENINSULA Northernmost point in Michigan Premier Mining Location from 1840 to 1968 Calumet was the second largest city west of Appalachians after Chicago at turn of the century At one time there was 1 stockbroker for every 26 residents of Calumet and area
6
Place Name Derivations Keweenaw – Indian for The Crossing Place Calumet – French for Pipe meaning Indian Peace Pipe Laurium – Mining City in Ancient Greece where Copper and Silver were Mined and Home of George Gipp and Al Stimac
11
THE PROLIFIC KEWEENAW 94.5% Cu Mined until 1929 came from a 3 mile by 26 mile strip between Mohawk and Painesdale Heyday was 1900-1918 Keweenaw District was Second Largest Producer of Copper in the World - 8.2 Billion Pounds Copper Mined - $325 Million in Dividends from 1845- today
13
Early Exploration Was Fostered By Ontonogan Boulder Circa 1670 explorers were viewing the boulder Ben Franklin Drew the Map of Settlement with Britain to Include Isle Royale After Michigan became a State in 1840 Douglass Houghton Led the Survey to The Keweenaw Legacy Short Lived - Drowned in 1845
15
ONTONOGAN BOULDER 3708 POUNDS
16
COPPER FORMATION IS CHEMICAL AND NOT VOLCANIC Hydrothermal Venting with Copper in Solution which Precipitated on Cooling Forming: Float Mass Amygdaloid Within other salts like calcite Fused with other metals like silver (half breed)
20
HALFBREED
21
DATOLITE WAS CONSIDERED A WASTE PRODUCT Porcelain-like Material Ranged in Size from Tiny to 140 lbs Calcium Boron Hydroxide Neosilicate Mineral Coloration Due to Inclusion of Copper or associated minerals from hydrothermal precipitation Caused Drills/Tools to Muck Up/Wear Out
25
MENARD MASS 18 TONS
26
QUINCY MASS 16 TONS
28
LARGE MASSES WERE CUT UNDERGROUND
29
Largest Mass Found in Minesota Mine in 1857 Estimated at 380 to 478 Metric Tons 52 ft x 16 ft x 9 ft 20 Men Took 15 Months to Blast, Hammer and Chisel it for Smelting Chisel Chips Alone Weighed 24 Metric Tons and Paid for Half the Labor
30
LATEST BOULDER FIND Offshore 1991 Seventeen Tons Removed in 2001 Destination Michigan Tech Mineral Museum at Quincy Steam Hoist
32
Boulders
34
19 TH Century Mining Early Mines were located near Lake Superior for Transportation Purposes Significant Amounts of Lumber Were Required for Shoring Up Drifts Trains Came Later Mills and Smelters Followed Mechanical Drilling Followed 3 Man Hand Chiseling
37
Many Ethnic Groups Contributed to the Copper Industry Cornish Croatians Finns French Irish Swedes Italians Norse Germans Poles Slovenes Scots There were up to Four or Five Churches of the Same Faith for the Different Ethnic Groups
41
Cliff Mine Operated from 1846 to 1856 $108K Investment Yielded $3.8M
49
HORSEPOWER LITERALLY
51
Modern Mining Methods Allowed Deep Shafts Original Mines Tended to be Hill Sides/Shallow Pits Steam Power Offered Means to Lower Man Trams and Raise Ore Trams Typical Mine Depths Were 1 Mile Deep Quincy was Deepest Mine at 9000 Feet
54
Calumet & Hecla’s Quincy Mine
57
NORDBERG 2500 HP HOIST
58
QUINCY MINE HOIST 30 Foot Drum Held 10000 Feet 1-5/6 Inch Wire(27 Tons) Could Hoist 10 Ton Skips at 34 MPH Largest of Its Type in the World
61
MECHANICAL DRILL REPLACED TEAMS
64
PREHISTORIC COPPER DEMAND Evidence of Tribes from 10,000 Years ago Lake Superior Tribes of 2600 BC to 1200BC Most Likely mined 20 Million Pounds Max Estimates mined 940 Million Pounds Trading Power - Tools & Jewelry & Weapons Cosmological Belief in the Manitou Midwest – New England- Georgia Other
65
CARBON DATING ISLE ROYALE
71
HOPEWELL
72
Copper Utensils and Kharma Were Drivers Many artifacts have been found ranging from fishhooks and spears to pots, plates and jewelry Copper pieces were Trading Power Ritual Belief Led to Sacred Offerings to Manitou Michigan Copper found from North to Midwest to New England/Southeast Atlantic
73
WHERE WAS THIS OTHER MARKET DEMAND One Man’s Theory - Pre Phoenician (Minoan/Cretan) - Sea Faring Traders - Alphabet Based on Guttural Sounds - Religion with Monolithic Worship -Flourished from roughly 3000BC to 1200BC
75
MEGALITH TRACKS Cyprus/Crete Sicily Corsica Majorca Almeria Lisbon Britany Stonehenge(3100-1100BC) Belfast Hebrides/Orkneys Iceland Greenland Labrador New England Minnesota/Michigan
77
SWEDISH DOLMEN
78
SALEM NEW YORK DOLMEN
79
MINNESOTA DOLMEN
80
MICHIGAN DOLMEN
84
The Ship Wreck of Ulu Burun 14 th Century B.C Ship Wreck Found off Coast of Turkey 50 Feet Long with Wooden Hull and Planks Held with Mortis-and-Tenon Joints Held 200 Copper Ingots weighing 60 Lbs Each (Equivalent to the Ancient Talent)
85
Claims of Diffusionists Need to be Verified To date X-Ray Crystallography has not shown American Copper as the Source in European/Mid-East Artifacts DNA of Native Americans Needs Research to Establish Origins More Research on Trade Goods That Might Have Been Used with Pre-Historic Miners
86
COPPER - A QUESTION FOR THE ANCIENTS & THE FUTURE Plenty of Copper Left in the Copper Country What Might the Natives Think About Open Pit Mining (National Park Status) Go there Yourselves & Experience the Environment, Copper Mine Tours, Mineral Museum Stay Tuned to Copper Sourcing in Europe/Mid East
