[D8950AAL], Letter from Walter Seeley Mallory to Thomas Alva Edison, July 6th, 1889



I send you a bag of ore, which if you can find some way to work - you can be well repaid - the property is owned by some Chicago people who have money - but they have been unable to find any way to get any value out of the ore - the following is the description they give me - "the manganese property is a patented one 600' - 1500' - from 80 arrays of carbonate and chloride (from deep workings) $79 per ton of silver in the average - the capping on them and adjacent property in manganese - We cannot give you the estimare tonage, but it is large and easily worked - likely could be moved for $.50 per ton as it is in good working shape. Carnegie Brothers of Pittsburg say "the ore is too high in silica to be used in the manufacture or manganese metals - but that it is the best kind of gold property. The 27000/1000 ounce gold is equal to $54 - the maganese freed from silica and concentrated to 68 percent with .04 phosphorus would be equally valuable." What they want is of course to save both the gold and the manganese - but in case that could not be accomplished, they would like to get one or the other - if you can find something that will do the work - you could receive very liberal returns - trusting that you will find time to look into the matter.
