can someone

Can someone please let me know what the geological evidence is for potash within the lease area? Do they have some rock chip data, or old drillhole data, that gives this evidence? The company line is not clear on this (sorry if this repeats something already discussed; I am a complete newcomer to this stock):

"About the Project
Transit has entered into an agreement giving it the right to earn up to 90% in the Project.
The Project covers applications for 89,000 acres of highly prospective potash permits in the
Paradox Basin in south eastern Utah.
The Paradox Basin Potash Project is located close to the key agricultural regions of the United
States and as such is ideally situated to supply fertiliser manufacturers and agricultural
cooperatives in the western and south-western United States. The Project also has substantial
export potential given its excellent proximity to key US rail infrastructure.
An exploration target of 2.5 to 3.8 billion tonnes of potash ore at 20% to 30% KCl has been
delineated within the Project by independent consultants Agapito Associates Inc. and Transit
and its joint venture partner"
