David Cates · President & CEO of Denison Mines (DNN), building the Phoenix in-situ recovery uranium mine at Wheeler River in Saskatchewan's Athabasca Basin.
19%-owned by Denison (board seat), run by ex-Denison / IsoEnergy-Hurricane people; works Denison's non-core Murphy Lake North and Darby ground — “some good success”.
Own company: Phoenix ISR in full construction, first production 2H-2028 at ~6M lb/yr; ~$600M post-FID capex funded by a convertible + physical-uranium sales (low dilution risk); Griffin funded from Phoenix cash flow for a 15–16-yr, 100M+ lb Wheeler River.
Holds an option on 10 Denison properties (51% vested, up to 70%); Denison owns ~20%. Its Nasdaq listing is the untapped angle: a Denison-sponsored Athabasca explorer for US investors.
Denison-backed neighbour east of Wheeler River: Russell Lake consolidated then split into four JVs, with Denison earning in at Wheeler North. A sponsor's “exciting story”.
Bought 2.5M lb in 2021 under $30/lb; now selling it to fund Phoenix — 350k lb fixed at ~$95, above recent market prices. Utilities are keen, so contracting stays slow and mostly market-related to avoid capping the price.
French state-owned uranium operator active in northern Saskatchewan: Denison's JV partner and operator of McClean North SABRE and the McClean mill; also a labour-market reference.
In one line: Denison is building Phoenix, the first new large-scale Athabasca uranium mine since Cigar Lake. As an in-situ recovery mine it takes ~2 years to build, so first production is due in 2H-2028 at ~6M lb/yr, ahead of any comparable new supply before the early 2030s. It is funded without heavy dilution (a convertible bond plus physical uranium bought under $30 and sold at ~$95), Griffin is to be paid for from Phoenix's cash flow, and future output is sold slowly and mostly market-related so it doesn't cap the price. The pitch to utilities: incumbents "have been clear that growth is not a priority," so new supply comes from emerging producers, and Denison — inventory, McClean North output, then Phoenix — is the low-risk one. Read everything here as a CEO's view of his own company.
Execution, not exploration, is the story now. CNSC licence in February, FID at the end of February, early works from March, full-scale construction with a night shift from end-July; site clearing beat migratory-bird season and subgrade work is done for the plant, well field and power areas. Year-end milestones: process-plant concrete and enclosure, power infrastructure, the well-field freeze wall (2026-SEP-10). In March, the plan was a 2-year build targeting mid-2028, with year one on the plant slab and a freeze fence that takes 12–14 months to establish (2026-MAR-31).
Speed to market is the edge. No shaft, pit or mill, just wells and a small plant made possible by the deposit's grades. At ~6M lb/yr for 10 years (front-loaded at 8–9M lb/yr in the first 5) it would be "one of the largest uranium mines operating in the world," with "not a great depth of projects in that scale" arriving before the early 2030s.
Financing designed to avoid dilution. ~$600M post-FID capex (~$700M all-in) funded by a US-style convertible and the 2021 physical-uranium stockpile (2.5M lb at just under $30). Of the 1.1M lb left at end-Q2, 350k lb is sold fixed at ~$95, 250k lb floats, and ~500k lb is uncommitted for the next 1–2 years. At end-2025 Denison held just under $700M in cash, physical uranium (1.85M lb, incl. ~150k lb from McClean North SABRE, its Orano-operated JV) and investments; post-FID capex had risen to ~$600M from the 2022-dollar 2023 study, and grid power shields the freeze wall from diesel costs (2026-MAR-31).
Sequencing turns one mine into a complex. Griffin (underground, $737M, ~3 km away) reuses Phoenix's road, power and camps and is timed to Phoenix's cash flow, making Wheeler River a 15–16-year, 100M+ lb operation (in March he put it at 16–18 years).
Measured contracting. In March, commercial lead Geoff Smith described a 5M lb deal with US$10M upfront (repaid as a per-pound discount) and 12M lb more in advanced negotiation, priced mostly market-related and diversified by tenor and counterparty, because a low-cost, low-debt producer can live with price swings (2026-MAR-31). By September, ~8M lb contracted plus ~7M lb in advanced negotiation was "an excellent foundation"; beyond that, "our life of mine production is not on sale right now." Supply that is offered, even if never placed, weighs on price, and utilities are keen enough that Denison can be choosy.
Exploration through sponsored juniors. Non-core ground goes to Skyharbour (Russell Lake JVs), Cosa (19%, board seat) and Nasdaq-listed Foremost (~20%, option on 10 properties), so it gets drilled with outside capital while management stays focused on Phoenix. Denison keeps a 30% asset-level interest in the Cosa and Foremost vend-ins and an option to earn up to 70% of two Russell Lake JVs ("team Denison", 2026-MAR-31).
Main risk flagged: labour. Denison, NexGen, BHP's Jansen, Eldorado's Foran copper project, Cameco and Orano all draw on a province of ~1.5M people. "Anyone who tells you that it's an abundance of labor in that province is probably not being totally truthful."
