I thought of that, but Tarku's PR says...

"The Project encompasses a total of about 1,250 hectares (13 km2) adjacent to the South of the Tombstone city, Cochise county, Arizona and consists of a combination of BLM claims as well as patented and unpatented claims...."

LBSRs announcement concerning the acquisition of a claim in the area says, 
"TUCSON, AZ–(Jul 27, 2020)–Liberty Star Minerals (“Liberty Star” or the “Company”) (OTCPK: LBSR) is pleased to announce the Company has received 2 Mineral Exploration Permits (MEPs) issued by the Arizona State Land Department (ASLD) covering the 240-acre Robbers Roost exploration area approximately 4.5 miles southwest of Tombstone, Arizona with access via paved road (Charleston Road). The new MEPs are 5.89 miles west of Liberty Star’s Hay Mountain Project for porphyry copper, gold, and molybdenum."  [Extract with emphasis added.]

While "our" Robbers Roost may or may not be involved with Tarku Resources, it would only be as one of multiple parties composing the balance of over three thousand acres.  That means that whatever monies are expended by Tarku only a tiny fraction would go to LBSR, if anything at all.

Anyway, it will all be made clear soon, if not my LBSR/Tracy, then by Tarku.
