There's a bit of news on the Holbrook basin potash deposit. [Right, potash salt. Credit, USGS]
Passport Potash today cancelled a deal to acquire the mineral rights of NZ Legacy Resources, which comprise 50% of the HNZ Legacy potash lands. HNZ is a joint venture between NZ and Hunt Oil.
And two days ago, officials of American West Potash met with the REAL AZ Corridor regional economic development organization to describe their plans to begin permitting an underground potash mine starting in March 2012 and seek support of the local community. The Arizona (Holbrook) Journal offers a detailed report on the meeting, which says the company expects some opposition because of the juxtaposition of the potash and Petrified Forest National Park.
Another issue is likely to be potential use of and impacts on ground water, including from salt byproducts stored on the surface. AWP said they will probably give away the salt to highway departments.
AWP made the point that the proposed underground operation does not have the "endangered species, rivers, and streams" issues that have generated concerns over some proposed open-pit mines.
If I haven't said it before, I'm impressed with the depth and quality of coverage by the Arizona Journal on the potash play.
