Determine Prices for Aval<strong>on</strong>’s Product<br />

Metallurgical tests have shown that <strong>the</strong> rare earth elements can be precipitated as a bulk oxide<br />

c<strong>on</strong>centrate. This product requires fur<strong>the</strong>r processing to match <strong>the</strong> pricing basis of separated,<br />

99% pure REOs. Pay factors for individual REOs c<strong>on</strong>tained in a mixed c<strong>on</strong>centrate are highly<br />

variable and dependent largely <strong>on</strong> supply and demand at <strong>the</strong> time of separati<strong>on</strong>, and sales<br />

c<strong>on</strong>tracts for <strong>the</strong> particular separator involved. Scott Wils<strong>on</strong> RPA reviewed Aval<strong>on</strong>’s<br />

assumpti<strong>on</strong>s for <strong>the</strong> various pay factors for <strong>the</strong> HREOs and LREOs and determined that <strong>the</strong>y<br />

were reas<strong>on</strong>able and c<strong>on</strong>sistent with current industry norms in China. Fur<strong>the</strong>r, Scott Wils<strong>on</strong><br />

RPA (2010) suggested that <strong>the</strong>re was no reas<strong>on</strong> to believe <strong>the</strong>re will be significant changes to<br />

<strong>the</strong> factors in <strong>the</strong> future.<br />

A final price for Aval<strong>on</strong>’s proposed rare earth oxide product is <strong>the</strong>n determined by multiplying<br />

<strong>the</strong> average c<strong>on</strong>centrati<strong>on</strong> of <strong>the</strong> individual rare earth oxides in <strong>the</strong> rare earth carb<strong>on</strong>ate<br />

c<strong>on</strong>centrate by <strong>the</strong> individual rare earth oxide prices and <strong>the</strong> payable factors as detailed above.<br />

This results in an average price for <strong>the</strong> rare earth carb<strong>on</strong>ate product in 2014 of US$21.94/kg.<br />

This price has been used in preparing <strong>the</strong> financial analysis detailed in <strong>the</strong> <str<strong>on</strong>g>report</str<strong>on</strong>g>.<br />

Aval<strong>on</strong> understands that separati<strong>on</strong> of <strong>the</strong> REE into multiple fracti<strong>on</strong>s will attract higher prices.<br />

However, at this time it is not possible to estimate this increase, as no data is available <strong>on</strong> <strong>the</strong><br />

differential between unseparated and partially separated REE. C<strong>on</strong>sequently, for <strong>the</strong> purposes<br />

of <strong>the</strong> pre-feasibility study, <strong>the</strong> base case has been a single REO c<strong>on</strong>centrate. Research into<br />

<strong>the</strong> pricing of separated REE is also recommended to determine <strong>the</strong> factors suitable for two<br />

products and three product situati<strong>on</strong>s, which are assumed to attract higher factors.<br />

NIOBIUM<br />

Niobium Market<br />

Niobium is a refractory metal closely associated with tantalum. Niobium is produced as a<br />

primary c<strong>on</strong>centrate from pyrochlore ore, and as a co-product in <strong>the</strong> producti<strong>on</strong> of tantalum<br />

c<strong>on</strong>centrates. Niobium finds its primary uses as an alloying agent in <strong>the</strong> producti<strong>on</strong> of high<br />

strength low alloy steels (HSLA), in selected aerospace alloys and in stainless steels. In <strong>the</strong>se<br />

applicati<strong>on</strong>s, <strong>the</strong> primary product form is as FeNb, TiNb and ZrNb. FeNb has a typical analysis<br />

of 66% Nb. FeNb and related alloy products account for over 90% of total niobium c<strong>on</strong>sumpti<strong>on</strong>.<br />

Niobium is also used in electr<strong>on</strong>ic and optical applicati<strong>on</strong>s, in superc<strong>on</strong>ducting magnets, fine<br />

ceramics, and as a corrosi<strong>on</strong> resistant metal for chemical process equipment. Niobium for <strong>the</strong>se<br />

applicati<strong>on</strong>s is c<strong>on</strong>sumed in <strong>the</strong> form of niobium powder as Nb 2 O 5 , as pure niobium metal and<br />

as niobium salts, primarily as <strong>the</strong> potassium salt K 2 NbF 7 or its derivatives.<br />

Reported world producti<strong>on</strong> of niobium is detailed in Table 18-24:<br />
