IRON ASSAYS - FURTHER DRILL TARGETS IN NORTHERN PORTION OF MT BEVAN
PROJECT
• Sampling within the northern half of the Mt Bevan Project identifies new target
zones with consistently strong iron assay results (>55% Fe)
• New target zones associated with favourable crosscutting structures along strike of
demagnetized BIF units and are primary drill targets.
• Targets identified in the north of the Mt Bevan Project covered by existing
archaeological and ethnographic surveys.
• Results from beneficiation testwork of detrital haematite / goethite layers throughout
the southern portion of the Mt Bevan licence due shortly.
Hawthorn Resources Limited (‘Hawthorn’), ASX Code: HAW, is pleased to announce
results of further rock chip and geological mapping programs carried out within the
Company’s 100% owned Mt Bevan Iron Ore project. The project is located on tenement
E29/510 approximately 100 kilometres west of Leonora, Western Australia and is located
along strike of the “Mt Mason Iron Ore Resource” (5.75 Mt @ 59.9% Fe) of Jupiter Mines
Limited (‘Jupiter’). Figure 1.
The focus of Hawthorn’s recent exploration has been within the northern half of the
tenement area in the strike extension of the sequence Banded Iron Formation (BIF) units,
interbedded sediments and rarer mafic volcanic intrusives that host both outcropping and
non-outcropping high grade haematite mineralisation to the south.
Access to the northern portion of the tenement area is difficult and it is considered unlikely
that exploration for potential haematite mineralisation has ever been undertaken.
Spot and composite rock chip sampling has identified three new target areas that exist as
discrete drill targets of 8-30 metres width and 500-1200 metres of linear strike length.
Each target is associated with crosscutting fault offsets and a complete loss of magnetic
response of interpreted host BIF units.

The sample results in target areas N1 and N2 in particular are considered encouraging as
both targets are accessible from existing tracks with the eastern margins of both zones are
obscured by laterite and kanga scree. The strike extension of these targets, in the N3
area, is covered by windblown sand however rare patches of haematite enriched float
were observed but were not sampled.
Target area N4 is less accessible and further sampling maybe required, whilst samples
throughout target N5 was focused on a thick layer of exposed folded magnetite enriched
BIF and sediments believed to be the strike extension of the thick magnetite sequences
observed in the southern half of the tenement.
As previously announced several drillholes displaying shallow, 12-16 metre thick, flat-lying
zones of haematite-goethite mineralisation, have been bulk sampled and submitted to
Amdel Metallurgical Laboratories, Perth for screen, gravity spiral and other beneficiation
testwork.
These samples, of a pervasive layer identified above primary, high grade haematite
mineralisation and in palaeo-channels throughout the tenement area, may be similar to
channel or detrital iron deposits and could represent a near surface resource of iron ore
fines. If this material can be upgraded to a saleable iron ore product it will significantly
improve the economic viability of future mining operations in the district and provide a
series of new exploration target in the project area. Results from this testwork are
expected during September.
Further drill testing of targets at Mt Bevan is expected to commence during October,
following RAB and RC drilling programs on gold targets in the Trouser Legs, Pinjin and
Deep South project areas that will commence on the 12th of September.
