You asked LDM:
"Thanks for the additional information regarding the Loveless Collection. Hopefully I will have the opportunity one day to sit down and go through the material. Just curious did she ever talk about the Dutchman having different types of Gold ore. Probably never came up but I thought I would ask."
Perhaps he answered in private, but others may have an interest in the answer.
Loveless dedicated the last three pages of her piece on the LDM, to the "reports" of "Jake's Ore". That would be pages 134, 135 and 136.
"When Jake paid the shoemaker, Charlie Rodig, with ore for mending his shoes, he paid him with gold in pale yellow quartz. The ore he gave to Julia Thomas to pay the mortgage on her house, was gold in white quartz. He was known also to have had wire gold in black quartz, and nugget gold in pink quartz."
"When Jake died, in 1891, some rich pieces of ore were found in a small chest under his bed. These may have come from his bonanza, but there is nothing to confirm this. The ore disappeared the day of the funeral, and no description of it was made known to the palpitating, prospecting public."
Lot's of important information for those who are hunting the LDM is coming out on the old forum. Well....perhaps it is really more important as fill material for someone writing a book on the LDM.

The research that has been done into the hstory of the major players in this mystery, is astounding.
You may be correct as to the importance of LDMs old posts concerning geology. I assume that is what you were referring to.
According to Loveless, Jake discovered his mine about 1874.
Waltz told Charlie Rodig "absolutely nothing" concerning his mine. Charlie got all of his information "from others". I don't know that there is any proof that Charlie ever found anything. The story told by Loveless indicates that he found a rich "placer'. He and his cook were attacked by Apaches, ran from the location, and he was never able to re-find it. It was on "the north side of the river, in the vicinity of Four Peaks". Many believed it was Waltz's placer.
