According to the Mojave Desert Dictionary:

The Sam Houston No. 1 Mine: A silver mine in the Calico Mountains that was discovered  by Hugh Stevens and sold to a Mr. Johnson, who then sold it to two Frenchmen for $40,000. They changed the name to Blackfoot Consolidated No.1 Mine.

Then, oddly enough:

The Sam Houston No. 2 Mine: A silver mine in the Calico Mountains that was discovered  by Hugh Stevens and sold to a Mr. Johnson, who then sold it to two Frenchmen for $40,000. They changed the name to Blackfoot Consolidated No.2 Mine.

And to further complicate matters …

The Sam Houston No. 3 Mine: A silver mine in the Calico Mountains that was discovered  by Hugh Stevens and sold to a Mr. Johnson, who then sold it to two Frenchmen for $40,000. They changed the name to Blackfoot Consolidated No.3 Mine.

Mysterious, or what?
