Fission study shaves capex, build time for PLS SASKATCHEWAN
| Underground-only plan simplifies uranium deposit’s development BY JEAN LIAN

ission Uranium (TSX: FCU; US-OTC: FCUUF) has released an updated prefeasibility study (PFS) for an underground-only mine at its wholly owned Patterson Lake South (PLS) uranium project in northwestern Saskatchewan. The updated PFS follows an earlier study of an openpit and underground operation released in April. The PFS tables a 1,000-tonneper-day underground mine that will process 2.3 million tonnes grading 1.61% uranium oxide (U3O 8) for 81.4 million lb. U3O 8 over its seven-year mine life at average unit-operating costs of US$7.18 per lb. U3O8 . It forecasts a $702-million, aftertax net present value (NPV) at an 8% discount rate, and a 25% after-tax internal rate of return (IRR). This is an improvement over the hybrid study, which tabled a $693-million, after-tax NPV at an 8% discount rate, and a 21% after-tax IRR. The change from an open-pit and underground mine to an underground-only operation is also expected to yield a 21% reduction in initial capex from $1.5 billion to $1.18 billion, and shaves the construction time line from four to three years. The payback period is 2.5 years. The lower capex and shorter construction time is attributed to simplified water-control measures, the company says. The revised mining method eliminates the need for a system of dikes and slurry walls, dewatering and overburden removal, which will lower total mine-related earth movement 90% to 5.4 million tonnes — down from 51.2 million tonnes in the previous PFS, along with a 58% reduction in disturbed area. The company’s 310 sq. km PLS
project, 550 km northwest of the city of Prince Albert and 150 km north of the community of La Loche, is home to the world’s richest uranium mines. Ross McElroy, Fission’s president and chief operating officer, says the company had initially looked at mining the shallow deposit as an open pit. “Normally when the deposit is 50 metres below the surface, an open pit is your preferred method to get to it. And it showed a very viable and attractive scenario,” McElroy says. But the open-pit mining option would involve a high-capital requirement of building a berm wall around the deposit, as two of the five mineralized zones — the R780E and R1620E zones that make up the eastern region of the Triple R deposit — are located beneath Patterson Lake, where the water depth is generally less than 6 metres and overburden thickness is 50 metres. “Because you have a lake sitting there, the Patterson Lake itself, you would have had to build a berm wall around the deposit, which is certainly technically viable, and it has been done many times on several deposits in northern Canada,” McElroy says. “But it is expensive.” As a result, the company looked at the alternative of mining the deposit through an underground mine while it was completing the PFS on the open pit. “We would save a significant amount of capital of at least $300 million, or more,” McElroy says of the underground-only option. “You are still looking at just over $9 per lb. U3O8 of operating costs, almost on par with an open pit ... I’m 95% confident that the underground-only option is the way to go forward.” The uranium project hosts the See FISSION / 15

Implats offers $1B for North American Palladium M&A
| Shareholder Brookfield enters agreement to sell its 81% stake BY STEVE STAKIW

Special to The Northern Miner
yeing its first major operations investment outside of Africa, platinum group metals (PGM) producer Impala Platinum Holdings has struck a friendly deal to buy Canadian pure-play palladium producer North American Palladium (TSX: PDL; US-OTC: PALDF) in an all-cash transaction valued at $1 billion. The proposed takeover gives Implats the Lac des Îles palladium mine, located 100 km northwest of Thunder Bay, Ont., its first PGM operation outside of South Africa and Zimbabwe. The definitive arrangement agreement sees Implats acquire all of North American Palladium’s shares under a two-tiered pricing structure. Brookfield Business Partners (TSX: BBU.UN) — North American Palladium’s controlling shareholder, with an 81% interest — will sell its shares to Implats for $16 apiece, at a 19% discount to the trading price before
the announcement. The remaining minority shareholders reap a better price, getting $19.74 per share, a 15% premium on North American Palladium’s 30-day, volume-weighted average price and the exact closing price of the stock before the takeover news. In a conference call, North American Palladium president and CEO Jim Gallagher discussed the company’s turnaround and the merits of the Implats agreement. “We have a sale of the company in an all-cash deal at near-record palladium prices, and except for a two-day blip in March of this year, at near recordhigh share prices for the company,” he said. “From virtual bankruptcy four years ago, we now have a sale to the tune of $1 billion. The company has been described recently by two separate analysts that cover us as the best free-cash-flow operation in their coverage universe.” Gallagher noted that Brookfield first got involved with the company in 2013, when North American Palladium was “in financial trouble,
with a mine expansion that had gone somewhat poorly. “In May of that year, the company had tapped out all its financial resources, had tapped out the equity See NA PALLADIUM / 2 PM40069240
