Due to a number of strategic and competitive advantages including shallowness of the potash deposit, existing infrastructure, and proximity to year round markets Prospect plans to develop, build and operate a conventional potash mine and state of the art production facility.
It is the commitment of Prospect to conduct operations in ways that protect the environment and safeguard employees and the public from unacceptable risks. Through integrated business plans, defined goals, priorities and decisions, we will establish a base for sustainable development by conserving resources, maximizing the resources we develop and optimizing opportunities to enhance environmental, social and economic benefits.
The Supai Salt has been divided into 5 cycles, of which the uppermost sequence, cycle 5, contains potash mineralization. The potential mineralized zones are found between 800 to 2000 feet (243 to 609m) below surface. Sylvite-mineralized strata typically occur in the upper portion of evaporite sequences.This depth is very similar to the Carlsbad mine in New Mexico and is relatively shallow when compared to other potash basins in the world.
In comparison to other deposits around the world, the Holbrook Basin has several competitive advantages:
Potash in the Holbrook Basin lies in two primary seams within the Supai Formation, the KR-1 and KR-2 seams. The KR-1 seam lies above the KR-2 seam and is unevenly distributed throughout the basin. The KR-2 seam is the primary target for delineation and development. in August 2012, North Rim produced an NI 43-101 compliant technical report which estimated the Holbrook Project Resource in accordance with CIM standards and using a 40%-ft (grade x thickness) cutoff estimated the following:
