CRU Value-In-Use Market Analysis Determines 94% Nickel Payability For Dumont Concentrate Grades (Compared to 70-75% Market Terms for Traditional Smelting/Refining)

TORONTO, Aug. 23, 2018 /CNW/ - RNC Minerals ("RNC") (TSX: RNX) is pleased to announce it has received positive results from CRU's value-in-use market analysis on RNC's innovative roasting approach on several different nickel concentrates, including the nickel-cobalt concentrate grades expected to be produced by the Dumont Nickel-Cobalt Project ("Dumont").

Dumont is the largest undeveloped nickel reserve in the world and second largest undeveloped cobalt reserve¹. CRU is the leading provider of analysis, prices and consulting in the mining, metals and fertilizer markets.

"CRU's market analysis determined a significantly higher value from RNC's roasting approach over traditional smelting and refining. The 25% improvement in payability calculated for nickel concentrates would allow a producer of various nickel concentrates to realize an additional US$1.10 for every pound of nickel in concentrate produced at current $US6.00 per pound nickel prices," said Mark Selby, President and CEO of RNC Minerals.

"This benefit provides tremendous leverage as nickel prices increase," continued Selby. "Dumont is expected to produce the highest-grade nickel (29%) and cobalt (1%) sulphide concentrate in the world², providing maximum flexibility for potential partners and offtake parties from a wide range of nickel consuming sectors, including the battery and stainless steel markets."

The CRU study looked at toll-processing in Asia for a range of nickel concentrates with nickel content ranging from 14% to 29% through to a final ferronickel product. It found that net payabilities utilizing this approach for all concentrates were significantly higher than current market terms based on CRU's estimate of long-term nickel prices, product premiums, and tolling costs. For a 29% nickel concentrate, which is the grade expected to be produced from Dumont, the nickel payability for concentrate was estimated to be 94%, or 25% higher than the top end of the estimated current 70-75% market range for nickel sulphide concentrates.

Alternate Roasting Approach
RNC's alternate roasting approach allows for the use of nickel concentrate by a wide range of nickel consumers, including large scale integrated NPI/stainless plants converting feed into finished product at higher recoveries and significantly lower processing costs, resulting in expected payabilities that are much higher than traditional smelting and refining.

RNC successfully completed a bulk concentrate test in early 2016 and, in co-operation with a leading Japanese trading house, successfully delivered roasted concentrate samples to multiple potential end users across Asia and Europe utilizing RNC's alternate roasting approach (see RNC news releases dated December 15, 2015 and May 17, 2016).

RNC believes that market prices over the last several years from traditional nickel smelters and refiners results in the concentrate producer receiving approximately 70-75% of the contained value of the nickel in the concentrate, allowing the smelter/refiner to capture 25-30% of the concentrate value (less their operating costs and recovery). 

After successfully demonstrating the potential of roasted nickel concentrate as a more valuable alternative to traditional smelting and refining in 2011, RNC worked with the Tsingshan Group ("Tsingshan"), beginning in 2012, to validate the concept. In 2014, Tsingshan began construction of the first plant to directly utilize nickel sulphide concentrate as part of the stainless steel making process and has since built an additional plant utilizing the roasted nickel concentrate approach. Additionally, Tsingshan signed an offtake agreement with Western Areas Ltd. in late 2016. RNC believes Tsingshan's successful use of roasted nickel concentrate in their production facilities in China is an important development for the nickel market (see RNC news release dated November 28, 2016).

RNC's work with a large Japanese trading house indicates that roasters in Asia are able to process feed at an approximate cost of $30/tonne. When combined with the average integrated NPI/stainless conversion cost of approximately $80-$90/tonne (according to Wood Mackenzie), the implied conversion cost is approximately $110-$120/tonne of concentrate (equivalent to approximately $400 per tonne of contained nickel for a 29% concentrate or approximately 3% of the current LME price of $13,800 per tonne). This compares very favourably to the 25-30% of the concentrate value believed to be currently captured by traditional smelters/refiners. The CRU value-in-use study is expected to be used to estimate the terms that roasting market participants would require to be willing to process the nickel-cobalt concentrate expected to be produced by Dumont as compared to these current market benchmarks (see RNC news release dated March 1, 2018).

CRU Methodology to Determine Value-In-Use
CRU has considered a scenario under which Asian processors would process nickel concentrate on a tolling basis. This means that the concentrate producer would retain ownership of the ferronickel product, and simply pay the processor to cover their costs, plus a margin.

The tolling costs were derived by estimating the operating costs and margins at a typical NPI producer using CRU's Nickel Cost Model and the estimated operating costs and margins at a typical roasting facility. CRU adjusted the NPI producer costs by assuming that the higher nickel content of the concentrate means that lower amounts of power, reductants, and energy would be required in the furnace for each tonne of nickel produced. The assumption is made that this relationship is linear, and that other costs remain constant. An additional margin to incentivise the switch to using nickel concentrate rather than their typical feed was then applied to these costs.  Due to the current and forecasted thin margins at some NPI producers, only a relatively small incentive payment would be required to encourage such NPI producers to use a nickel concentrate for feed instead of their current laterite feeds.
