Comments

Comment (Production): Total Production Estimated At $22,000. A Small Amount Of Of Pb Ore Produced In 1915 Was 5 Or 6 Cars Of Ore Which Returned About $1000/Car. Item 8 Was 1 Or 2 Cars/Year. Item 9 And 10 For Returns From 4 Cars Hand-Sorted Ore; Item 9 From Upper Ore Body, Item 10 From Carbonate Ore Body. Item 11 Was Hand-Sorted Ore.

Comment (Location): About 2.5 Mi N Of Weimer Mine And Lies Partly Within Lemhi And Clark Counties

Comment (Development): 15 Claims - 7 Owned Jointly By Worthing And Kaufman, 6 Owned By Worthing, 2 Owned By Weaver ; Econ.Com: All Water Used Hauled 5 Miles From Birch Creek
