enCore solely utilizes In-Situ Recovery (ISR) for uranium extraction, a well-known and proven technology co-developed by the leaders at enCore Energy.
is committed to providing clean, reliable, and affordable domestic nuclear energy by becoming the next United States uranium producer in 2023. This provides a relatively inexpensive and instantaneous means for accurate assaying in-situ ore grades over large areas and allows for accurate ore body mapping, resource estimation, and wellfield planning.ĮnCore Energy Corp. The ratio of epithermal to thermal neutrons is proportional to uranium allowing the U 3O 8 ore grade to be accurately calculated. The neutrons emitted by the PFN tool excite, at an atomic level, in-situ uranium atoms in the drill hole creating fast (epithermal) neutrons and slow (thermal) neutrons. The PFN tool creates very fast neutrons (14MeV) and fires 108 neutrons per second.
PFN technology solves this issue by instead using neutron activation to detect uranium in drill holes. Without accurate in-situ measurement of uranium, significant high-grade ore has been missed using traditional downhole techniques. Traditionally, disequilibrium is calculated using mud rotary coring techniques and laboratory gamma and alpha spectrometry, all of which are expensive and time consuming. Consequently, the radioactivity measured in drill holes using traditional Total Gamma and Spectral Gamma methods does not accurately correspond to ore grade due to the continued decay of uranium daughter products including potassium, thorium, lead and bismuth relative to radium (Ra 226), a significant gamma emitter. Many geologically younger ISR uranium deposits in the United States, and particularly in South Texas, have a certain degree of disequilibrium. enCore's Alta Mesa ISR Uranium Project in South Texas, produced 4.9 million pounds of U 3O 8 between 20 from wellfields and mineral resources identified and measured using this PFN technology. PFN technology has played an important part in the development and advancement of uranium projects in the United States and South Australia. The Benefits of PFN (Prompt Fission Neutron) Technology
#ENCORE ENERGY 401K LICENSE#
Energy Fuels retains the right, subject to availability, to purchase, lease, and/or license at least one fully functional PFN Tool and all related and/or required equipment, technology and licenses as may reasonably be requested solely for their use, for a period of up to 20 years. The same conditions occur elsewhere in the United States including some deposits in Wyoming.ĮnCore currently uses PFN technology in its delineation of ore bodies in anticipation of installing production wellfields at the Company's South Texas Rosita and Alta Mesa ISR Uranium Projects. This is particularly applicable at enCore's South Texas properties where in-situ geochemical conditions allow some of the radiometric components, such as uranium, to be out of equilibrium with their gamma signatures. PFN technology is critical to successful in-situ recovery (ISR) uranium project development as it directly measures downhole U 3O 8 ore grade versus traditional Total Gamma and Spectral Gamma methods which measure radioactivity emitted from a variety of elements associated with uranium.

We are using this proven PFN technology right now as we install our production patterns in our soon to be producing wellfields."
We have already seen the benefits of the technology in the past with reliable uranium resource estimates derived from PFN that were confirmed by historical production results. Paul Goranson, enCore's Chief Executive Officer, said, "PFN technology is far superior to traditional downhole gamma measurements where an array of different elements emits a collective gamma signature which may or may not correlate well with the actual uranium content.
