[D8953AAS], Letter from Josiah Custer Reiff to Thomas Alva Edison, April 3rd, 1889

Editor's Notes

"I am interested in a Copper mine near [Sayerville?] N.J., which is now being developed with steam drills. The ore is stated to be very simple in combination. ## I have had a number of analyses made here & in Europe & all show about same result---Some specimens show a p.c. of silver & a grace of Gold. I have directeed a box of specimens sent to you & it will be a personal favor to me if you will have a careful analysis made under your personal supervisions & give me your opinon as to the most economical method of production. The Ansonia people report they have a process for treating this ore by Electricity at a low cost. I am told the metal produced of this copper ore is very pure. ## Thank you in advance, I am yours"
