She Weighed the Ore Twice: The Murder of Erin White

She Weighed the Ore Twice: The Murder of Erin White

A certified assayer who weighed samples twice and kept a card tally 231 tricks ahead was found dead; twenty-one days later a hidden jar with E.W. sealed in wax revealed a swapped ore sample that could destroy a company and condemn a man - who had access to box number four of six, and why did Erin, who had no key, have a jar stamped with her initials?

In this episode, we lay out the sequence of discoveries from April 22, 1893 through the telegraph reply on April 28, 1893, showing how a laundress’s find, a cash box, and a chemist’s analysis changed a routine death certificate into a case with corporate consequences; what does the assay logbook entry tied to box number four tell us about Erin White’s last days?

Person: Erin White
Date: April 22, 1893 (box found), death occurred 21 days earlier
Location: Coldwater Gulch boarding house
Occupation: Certified assayer for Harlow-Trench Mining Company
Analysis date: April 28, 1893 (telegraph reply from Frank Aldrich, Pueblo)

- Erin White was about 29 years old and held the only assay certification held by a woman in the Colorado high country.
- A laundress, Diane Becker, found a tin cash box behind a loose stone on April 22, 1893, containing a 4-inch glass jar sealed with green wax pressed with the letters E.W.
- The jar held low-grade silica aggregate with trace copper worth about $8 per ton, per Frank Aldrich’s analysis.
- The sample number on the jar matched an assay logbook entry for a high-grade silver chloride specimen worth roughly $240 per ton.
- The transport case containing that logged sample was box number four of six, logged out March 27 and returned March 29, two days before Erin White died.
