Newest Athabasca Basin Mine in Decades: $345M Funding Secured for 9 Mlbs Annual Production Potential

• Denison Mines is advancing toward final regulatory approval for its Wheeler River Phoenix ISR mine, with panel hearings scheduled for October and December 2025, and expected decisions within 90 days, targeting mid-2028 production of up to 9 million pounds annually.
• The company secured $345 million through an innovative convertible bond structure with capped-call protection that limits potential dilution to just 4% even with 200% share price appreciation, providing construction funding without traditional equity dilution concerns.
• Major uranium producers including Kazatomprom and Cameco continue struggling to meet production guidance while demand accelerates from data center growth and Microsoft's joining of the World Nuclear Association, creating favourable supply-demand dynamics.
• Denison maintains current cash flow through its 22.5% interest in McClean North mine production and holds 2 million pounds of physical uranium inventory, providing immediate revenue streams while developing the Phoenix Deposit.
• The company's strategic positioning includes advanced engineering completion (75%), ongoing procurement activities since 2023, and a diversified commercial strategy that enables flexible market participation without relying entirely on spot pricing or long-term contracts.

The uranium sector stands at an inflection point where surging demand meets constrained supply, creating what industry insiders describe as the most favourable market dynamics in over a decade. At the center of this opportunity sits Denison Mines (TSX: DML), a company positioning itself to capitalise on what CEO David Cates characterises as a fundamental shift in nuclear energy's role in the global power landscape.

From Data Centers to National Security

The uranium market's transformation extends far beyond traditional nuclear power generation. Microsoft's recent decision to join the World Nuclear Association represents a watershed moment for the industry. Cates explains:

"The fact that they're (Microsoft) joining and publicly joining the WNA I think is really icing on top of the news stories that have already occurred to, its really a public declaration of their link to nuclear power. They're a major player obviously and they use a lot of power."

This corporate embrace of nuclear energy reflects a broader recognition that data centers, artificial intelligence infrastructure, and cloud computing require massive, reliable baseload power that only nuclear can provide at scale. The implications extend beyond immediate electricity needs to encompass energy security and grid stability concerns that have moved nuclear power from environmental debate to national priority.

Utilities are responding accordingly, actively seeking new sources of Western uranium supply.

Supply-Side Reality Check

While demand accelerates, the supply response has proven disappointing across established producers. Cates offers a candid assessment of the industry's challenges:

"We've seen the restarts and the incumbents. They're the first wave of people to come back from our terrible times in the sector of low price. We have to remember that restarts are mines that were shut down. So, in some ways lower risk and they're not fielding from execution standpoint, but they're also not top tier."

The CEO's analogy proves particularly illuminating:

"It's a bit like taking a used car out of storage, right? Like a new car, usually reliable. That's why you want one, has a warranty with that kind of stuff. The used car, and then putting it in storage and then trying to bring it back to life, it's not that easy. And then when you do get it back to life, it's still a car that's been driven for whatever kilometers it was."

"We've got Kazatomprom, it's had multiple years now of struggles achieving production guidance. Cameco recently announcing that they'll fall short this year as well," Cates observes. "Look, uranium mining is complicated. It's tricky. There's a level of risk."

Phoenix Rising: Denison's Flagship Development

Against this backdrop of supply constraints and surging demand, Denison Mines presents a compelling development story centered on the Wheeler River-Phoenix deposit. The project represents what Cates describes as the first new large-scale mine in the Athabasca basin in decades.

The Phoenix in-situ recovery (ISR) mine offers several competitive advantages that distinguish it from conventional mining operations. The high-grade Athabasca Basin deposit is designed to produce up to 9 million pounds of uranium annually during its first four to five years of operation, with what Cates characterises as exceptional economics:

"It looks like it will ramp up quickly right, it's high grade in Athabasca, that could produce a billion dollars in free cash flow a year depending on uranium price."

Timing represents a critical competitive advantage. From discovery in 2008 to expected first production in mid-2028, Phoenix will achieve a 20-year development timeline that Cates acknowledges as exceptional:

"We would say we're an outlier to be able to have invested through all those bad years. That's the difference maker right now to where we are in the queue."

"We're in the final stages. Thank god of the regulatory approvals process," Cates explains. "The panel is scheduled to sit October and early December. The decision should be rendered, we would expect within 90 days."

Engineering and procurement progress demonstrates the project's advanced development status with the detailed design engineering is over 75%, the procurement's been in progress since 2023 and will be at 95% plus on total engineering by the end of this year according to Cates.

Interview with President & CEO David Cates

The Convertible Bond Innovation

Denison's recent $345 million US convertible bond offering represents sophisticated financial engineering that addresses traditional mining sector concerns about equity dilution. The instrument incorporates a capped-call structure that Cates describes as the first time this has been done by a Canadian domiciled TSX-listed company. The mechanics prove investor-friendly.

"The convert to Denison is now effectively only potentially diluted if we're up over 100%. So it would be like $4.32 share price before we would have capped-call coverage," Cates explains. "So essentially until our share price is over $4.32, we can settle the conversion of this bond or the units of the bond by paying back the principle in cash."

The structure's effectiveness becomes apparent in stress-testing scenarios. Beyond dilution protection, the financing provides cost advantages, Cates notes:

"We estimate this structure saves us over a hundred million less on interest cost compared to the best conventional project-secured project finance that we could have gotten as an alternate,"

First-Mover Advantages

Denison's approach to market timing reflects sophisticated understanding of uranium market dynamics. Rather than waiting for higher prices, the company pursues what Cates describes as a rerating from developer to producer strategy that generates value through operational execution rather than commodity price speculation. Cates explains.

"There's going to be incredible value to being in production having uncommitted or market exposed production. At a time when the market realises that there isn't actually enough, that will be good broadly for everyone because the value of everyone's uranium will go up because of how scarce it is. To be actually in a position to sell your uranium and realise that price and turn that into cash. That's what our first mover advantage will do."

The company's current production profile supports this strategy. Through its 22.5% interest in the McClean North mine, Denison generates immediate cash flow while developing Phoenix. Denison also has inventories that we could be sold anytime through to the end of 2027..

Market Strategy: Diversification and Flexibility

Denison's commercial approach reflects realistic assessment of market dynamics and competitive positioning. Rather than betting everything on spot prices or long-term contracts, the company pursues diversification.

"We are engineering our commercial strategy... and that means that we will have a diversified book of different types of contracts because some of them will work out in some situations and other structures will work out in other situations," according to Cates.

The company's size provides strategic advantages in market positioning.

"NextGen and Denison both, I don't think either of us sees each other as a threat. We both have top tier assets that are positioned to survive in every market scenario that you could imagine. We're mindful though that the market could go a few different directions depending on the bigger players than us."

Growth Platform: Beyond Phoenix

Denison's vision extends beyond Phoenix to encompass a multi-asset growth platform. with the Gryphon deposit development being funded from Phoenix cash flows. The company maintains exploration spending of C$10-C$15 million a year while pursuing strategic partnerships through what Cates calls "a bit of team Denison" approach.

The strategy includes selective acquisitions enabled by Phoenix's expected cash generation.

"Being in a position where Phoenix is producing and generating incredible free cash flow gives us great flexibility. We would want to generate a return on those cash flows. You have options in building internally or acquiring, but to be able to acquire without having to dilute is incredible opportunity for us," Cates explains.

However, the CEO acknowledges discovery challenges. The broader supply picture reveals structural constraints that extend beyond operational challenges.

"We do need discoveries to be made. We looked in our region for the last 10 years for deposits that we could acquire. It's not deep with a bunch of underexploited assets."

"Kazakhstan has its stable projects. The pipeline is not extra deep and they're barely keeping up at their guidance just as what it is. Cameco doesn't have major growth projects on the horizon. They've not been investing for some decades now," added Cates.
