permit (permit #1149) for an exploration core hole by HNZ Potash in the Holbrook basin. HNZ has had the lowest public profile of the three companies most active in the basin. Their last exploration core hole permit was issued in September 2011. Passport Potash and American West Potash (Global Prospect Resources) have had more active drilling programs and made announcements about plans to mine. HNZ is a joint venture of Hunt Oil in Dallas, and NZ Legacy Resources, a local land and ranching company.
