Just had to repeat this from November 28, given my posting of the Rosemont graphic below. This is a quote from a NR, not my words.
"Current understanding indicates that the latest targets may bloom into major mineral zones 200 to 400 feet in depth at their intersection with the Horquilla limestone, the major mineral host in the region. ... After ID of the lower part of the Earp, the Company’s skarn consultant (recently working on another Arizona project in the same sedimentary rocks, containing high grade copper) felt that there was a strong possibility that the two high grade copper oxide outcrops could be positioned right above high grade copper mineralization."
