Passport Potash Updates Geotechnical Drilling Program at Holbrook Basin Project

Passport Potash Inc. is pleased to announce an update on the geotechnical drilling program for its Holbrook Basin potash project (the "Holbrook Project").

The purpose of the geotechnical work is to investigate the soil and rock mechanics to help determine the mine design criteria for the Holbrook Project, and is expected to be incorporated into a Pre-feasibility study.

Passport's geotechnical drilling program includes two core holes (1212 and 1301R) that were drilled through the entire geologic section. Hole 1212 will be used to evaluate the overburden, while hole 1301R will be used to evaluate the salt body.

A total of 273.71 meters (898 ft.) of 85mm (3.35 in.) diameter continuous overburden core was recovered from the upper formation of hole 1212. Twelve one-foot overburden samples were sent to Advanced Terra Testing in Lakewood, Colorado on April 22, 2013 to perform a Triaxial Compressive Strength Test. The samples were prepped and testing began on June 10, 2013. Passport has received preliminary results on approximately half of the samples, and expects final results within two to four weeks.

Hole 1301R contains a total of 46.33 continuous meters (152 ft.) of 101mm (3.98 in.) diameter salt core. The salt body samples are being sent to IfG, Institute for Rock Mechanics GmbH, in Leipzig, Germany ("IFG"). IFG is a German engineering firm founded in 1990 by employees of the former Institute for Mining Safety in Leipzig and is based on more than four decades of continuously applied research in the field of rock mechanics. IFG will be performing the following tests on the samples:

  • Triaxial Compression Strength Tests
  • Triaxial Strength Tests with Relaxation
  • Long-term Triaxial Creep Tests
  • Direct Shear Tests

Joshua Bleak, Chief Executive Officer of Passport, stated, "The rock mechanical tests will help to optimize and increase the certainty of the data used for mine planning and mine safety. We are pleased to mark the achievement of a critical project development milestone that will help position us to meet our planned timelines for the forthcoming Pre-feasibility and bankable Feasibility studies."
