U3O8 were packaged in drums and 73,367 pounds of U3O8 drummed inventory were shipped out of the

Lost Creek processing plant . At December 31 , 2017, inventory at the conversion facility was

approximately 94,077 pounds U3O8.

In 2017, sales totaled $38.3 million from 780,000 pounds sold. Our overall price per pound sold averaged

Lost Creek Production Operations in Mine Unit 1 and Development of Mine Unit 2

Lost Creek celebrated its fourth anniversary of operations in August. At year-end 2017, we have captured

approximately 2.4 million pou nds U3O8 and have delivered approximately 2.2 million pounds of Lost

Creek production to our customers. At this time, our first mine unit (“MU1”) has recovered nearly 89% of

the estimated under -pattern resource, based upon the revised and updated Lost Creek Preliminar y

Economic Assessment (as amended, February 2016, the “PEA”). This is compared to an accepted industry

standard of 70% to 80% recovery of under -pattern resource. As well, project economics in the PEA were

based on an 80% recovery.

Drilling and other const ruction work to develop the first three header houses in Mine Unit 2 (“MU2”)

commenced in early April 2017, allowing us to bring the first header house online in late August.

Operations in the second header house in MU2 are expected to commence this week; we anticipate the

third header house will come online in Q1 2018. We are pleased to report that to date MU2 has

exhibited similar production characteristics to MU1. In addition, operational modifications have allowed

for higher sustained production flows supporting efficient future wellfield operations as well as optimum

recovery rates.

Our Class V water system worked well throughout its first year of operations. This system is the first of its

kind at an ISR uranium facility, having received all permitti ng and other authorizations at year -end 2016.

Allowing for onsite disposal of fresh permeate ( i.e., clean water) into shallow Class V wells, this system

also permits us to recycle significant amounts of what would normally be considered waste water.

Ultimately, the system reduces injection requirements in our Class I deep disposal wells and extends the

life of those very valuable assets.

Guidance for 2018

For 2018, we expect to deliver 470,000 pounds into our term contracts at an average price of

approximately $49 per pound. We have scheduled 370,000 pounds to be delivered in Q1 2018 . We will

provide further guidance for 2018 production and other operational matters in our Annual Report on

Form 10-K, which is currently anticipated to be filed on Friday, March 2, 2018.
