David Cates, President & CEO of Denison, stated the following on November 17 when the deal was first announced:

“Given its proximity to Wheeler River, Denison has had an interest in adding Russell to our property portfolio for much of my nearly two decades with the Company. This transaction achieves that objective by providing Denison with the opportunity to lead and participate in exploration efforts across four newly created joint ventures, which are designed to drive collaboration between Denison and Skyharbour’s technical teams.  We are excited to build on our long-standing relationship with Skyharbour and accelerate the evaluation of this exceptional package of highly prospective ground.”
