A new sequence of nickel sulphide bearing komatiites has been confirmed at the Lake Johnston project, Western Australia

Laboratory (petrographic) results of samples taken from an RC drill hole confirmed the presence of nickel sulphides in five out of seven samples submitted

Sulphides present in these samples include pentlandite, violarite, pyrrhotite and chalcopyrite

Strong coincident geochemical and magnetic anomalies exist in close proximity along strike (surface EM geophysical techniques ineffective in the area due to highly resistive ground)

Follow-up work including drilling and downhole geophysics is currently being planned

Hannans Reward Ltd (Hannnans) is pleased to announce the receipt of laboratory (petrographic) results that confirm the presence of komatiite-hosted nickel sulphide mineralisation from RC drilling at the Lake Johnston project. This newly found sequence of komatiites is located in the southern portion of the Lake Johnston tenement package within the Mt. Gordon prospect area (Figure 1). BACKGROUND & DISCUSSION A soil sampling program conducted in 2011 generated a coincident nickel/copper anomaly in the Mt. Gordon prospect area (Figure 2). The anomaly was followed up with a small, ground based moving-loop electromagnetic survey, however the survey was interpreted to be ineffective due to the highly resistive nature of the ground (survey penetration <100m depth) and failed to generate any significant anomalies beneath the surface. The soil anomaly was drill tested in early 2012 with a single RC percussion hole (MGRC059) which intersected a high-MgO ultramafic unit, returning elevated nickel values up to 0.56% Ni (Table 1).

Recent samples taken from MGRC059 were sent for petrographic and geochemical analysis; results from these two studies have now been received and have indicated the following results: •

MGRC059 indicates the presence of fertile, high-MgO, reduced komatiites with the presence of nickel sulphides;

Disseminated and trace primary sulphides present including pentlandite, violarite, pyrrhotite and chalcopyrite (Figure 3);

Nickel sulphides (pentlandite and/or violarite) were noted in five of the seven samples submitted for petrographic analysis (including at 76m, 117m, 132m, 165m and 172m downhole);

It is has been interpreted that at least two thick (>30 metres) komatiite units were intersected in the hole; 3 | Page

The komatiites intersected have a significantly high Ni-MgO ratio, indicating that they are enriched in nickel; and


The komatiites were emplaced in a reduced oxygen environment indicated by the low chromium content.

These results are highly encouraging for Hannans as they confirm the presence of a new sequence of nickel sulphide bearing komatiites, in an area which has no previous noted record of exploration for that style of mineralisation. It is noteworthy that just approximately two kilometres to the south of this komatiitic sequence lies the Medcalf intrusive, a large layered mafic-ultramafic intrusive which is known to host elevated concentrations of vanadium, titanium and iron. It is still unknown exactly what geological relationship exists between the two units.

FUTURE EXPLORATION Follow-up drilling and downhole geophysical surveys are currently being planned to thoroughly test the coincident geochemical and magnetic anomalies that exist along strike within the immediate vicinity (Figure 2). Further step out geochemical sampling is also currently being planned to cover the existing strike between the nickel anomalies and the Medcalf Intrusive.
