Major groundwater resources have been discovered
within the Yangibana Project tenements.
The quality is suitable for potable, metallurgical
processing and general water requirements
It is considered that there is enough water to satisfy
requirements for a proposed mining operation of 1
million tonne per annum for in excess of 15 years
A significant proportion of drill holes located within the
footprint of the Yangibana North and Bald Hill South
neodymium-rich deposits have intersected water
resources
There is potential to define further water resources
Access to this water will reduce capital and operating
costs and further enhance the economics of the project
In 2014 vertical drill hole YGBW1, located at the Yangibana
North deposit (Hastings 70%), was drilled as a water bore to
supply the diamond drilling operations. This year at Bald Hill
South deposit drill hole BHRC081 (Hastings 100%)
intersected significant water flows and is now also used to
supply water for exploration operations. The location of the
two holes in relation to Hastings’ major deposits is shown in
Figure 1.
Early in 2015 consultant ATC Williams was appointed by
Hastings to identify and investigate water resources as part
of the Pre-Feasibility Study. It was requested to include
these two holes in its investigations.

In June 2015 ATC Williams carried out a regional investigation of existing water bores on
Wanna Station, on which the Yangibana Project is located, and Edmund Station abutting
to the north. This regional work showed that generally similar good quality water
occurred throughout, including holes YGBW1 and BHRC081.
Water Quality
Depth to water in YGBW1 was approximately 17m and in BHRC081 was approximately
23m. Water samples from each were analysed. Results showed that:
1. Total dissolved salts were low at 870mg/L for YGBW1 and 1,300mg/L for BHRC081.
2. Water quality is good; with inorganic water quality parameters and dissolved
metal concentrations being within the “Drinking Water Guidelines” (ADWG)
although fluoride is marginally above the guideline value of 1.5 mg/l at 2.1 mg/l
and 3.0mg/L respectively.
3. Uranium concentrations are within the drinking water guidelines and thorium was
not detected.
Based on these results it is concluded that the quality of groundwater from both bores is
suitable for all purposes, including potable use. It is likely that this water is suitable for
beneficiation and hydrometallurgical processes; without the need for any treatment. This
will need to be confirmed during the Bankable Feasibility Study.

Aquifer Characteristics
ATC Williams undertook preliminary pump testing and collection of data to determine
permeability and porosity of host rocks at the two sites.
Initial pump testing indicates that both boreholes have intersected “confined” or “semiconfined” aquifers; essentially the mineralised ironstone and the enclosing adjacent
sheared wall-rocks.
Permeability and Transmissivity estimates are relatively high.
1. Yangibana North aquifer gave 1 x 10-4 m/s permeability and 5 x 10-4 m2/s
transmissivity.
2. Bald Hill South aquifer gave 4 x 10-4 m/s permeability and 2 x 10-4 m2/s transmissivity.
Estimated Storativity is sufficient to provide significant water supply during drawdown of
the confined aquifer and due to the unique porosity characteristics of the orebody, high
specific yield is anticipated during dewatering of the ore.
Calculations based on reasonable assumptions indicate that pumping from either of the
aquifers could supply in excess of 300,000 cubic metres of water per annum, which is
considered adequate to meet the requirements of the proposed processing plant,
probably for in excess of 15 years. Similar aquifers are likely to be found elsewhere within
the Yangibana Project over a 15 km strike length.
The hydrogeology of these aquifers is potentially quite complicated and further
collection of data is necessary before these conclusions can be verified, recharge
potential assessed and parameters accurately estimated. This will include examination
of core, measurements of piezometric water levels and full scale pump testing, and is
planned for the Bankable Feasibility Study.
Water resources are considered assured and are not a significant risk factor for the
proposed mining operation.

About Hastings Rare Metals
• Hastings Rare Metals is a leading Australian rare earths company, with two JORC
compliant rare earths projects in Western Australia.
• The Yangibana Project hosts JORC Indicated and Inferred Resources totalling
6.79 million tonnes at 1.52% TREO, including 0.35% Nd2O3 (comprising 3.96 million
tonnes at 1.59% TREO Indicated Resources and 2.83 million tonnes at 1.43% TREO
in Inferred Resources).
• The Brockman deposit contains JORC Indicated and Inferred Resources
totalling 36.2 million tonnes (comprising 27.1mt Indicated Resources and 9.1mt
Inferred Resources) at 0.21% TREO, including 0.18% HREO, plus 0.89% ZrO₂ and
0.35% Nb₂O₅.
• Rare earths are critical to a wide variety of current and new technologies,
including smart phones, hybrid cars, wind turbines and energy efficient light
bulbs.
• The Company aims to capitalise on the strong demand for critical rare earths
created by expanding new technologies. In late 2014 Hastings completed a
Scoping Study of the Yangibana Project that confirmed the economic viability
of the Project and in early 2015 commenced work on a Pre-Feasibility Study.
