High Grade Gold Intercepts – Edjudina
Hawthorn Resources Limited (ASX:HAW) is pleased to announce high grade gold results from
recent drilling at it’s wholly owned Edjudina Project area.
These results include:
o 2 metres @ 20.29 g/t Au (including 1 metre @ 39.5 g/t Au),
o 4 metres @ 4.28 g/t Au (including 1 metre @ 10.26g/t Au), and
o 4 metres @ 6.03 g/t Au
that confirm earlier reported high grade results, and further identifies the high grade gold zones
that are known to occur within this mineralised field.
Introduction
Hawthorn Resources Limited is pleased to update shareholders with results from recently
completed RC drilling carried out within the Edjudina – Triumph Project area, primarily
focused in the Senate Mine area.
The project area, approximately 145 kilometres North-east of Kalgoorlie and in close
proximity to existing mining operations and active ore haul roads, covers a series strike
parallel quartz veins. Three major, distinct and separate quartz vein sets (“Reef 1, 2 & 3”) host
most of the known gold mineralisation in the project area, from which historic gold production from
4 major underground mines totalled 33,215 oz @ 46.9 g/t of gold along 1.4 kilometres of strike.
Exploration and development by Paget Gold Mining Company Limited in 1983 resulted in
an estimated remaining underground Proven and Probable Reserve (to 160 metres from
surface) of 195,500 tonnes @ 12.4 g/t Au (75,000 oz Au).

Current Program
The recently completed drilling program on the granted Edjudina Mining Lease was focussed
beneath and along strike of the Senate Mine (10,398 oz of Au produced from 6942 tonnes of ore)
where historic drive sampling and drill intercepts of two of the parallel reef horizons (“Reef 2 and
3”) returned:
– 0.47 metres @ 157.0 g/t Au at 35 metres vertical depth
– 3.00 metres @ 11.3 g/t Au at 66 metres vertical depth
– 0.25 metres @ 189.2 g/t Au at 132 metres vertical depth
beneath and within the historic mine workings.
Previously drilling by Hawthorn in the Senate South area intersected a zone of high grade Reef 2
mineralisation near surface.
– 2.0 metres @ 15.75 g/t Au at 28 metres vertical depth
During the current program single and two hole drill sections were drilled over 600 metres of strike
with most holes intersecting at least one, if not two, of the known parallel reef positions.
The results from the current program are considered extremely significant as drill sections south,
immediately to the north and beneath the excavated Senate Mine Lodes have returned very high
gold grades at relatively shallow depths including:
o 2.0 metres @ 15.75 g/t Au from 36-38 metres - EDC006,
o 4.0 metres @ 4.28 g/t Au from 54-58 metres – EDC017,
o (including 1.0 metre @ 10.26 g/t Au),
o 2.0 metres @ 4.32 g/t Au from 87-89 metres – EDC018,
o 1.0 metres @ 6.01 g/t Au from 62-63metres – EDC022,
o 4.0 metres @ 6.03 g/t Au from 40-44 metres – EDC028, and
o 2.0 metres @ 20.29 g/t Au from 108-110 metres – EDC033,
o (including 1.0 metre @ 39.5 g/t Au)
These results have confirmed that the main gold ore bearing lode in the Senate Mine area
appears to be the quartz – carbonate Reef 2 system, which flattens in dip with depth. Reef 2 has
been intersected in most holes drilled in the vicinity of the Senate Mine shaft, with over 300 metres
of gold mineralised strike intersected to date. Some resampling of existing drilling is required as
several samples of holes in the Reef 2 position reported strongly enhanced results in initial
sampling with respect to the results reported in the table below.
Nonetheless the drilling and sampling carried out indicates that well defined, high grade gold lodes
exist in this area. Drilling to further define these lodes and potentially identify a mineable high
grade gold resource amenable to open-cut and / or underground exploitation will be carried out in
upcoming months.
Results from the drill program are reported in Table 1 below.

Summary
Hawthorn is encouraged by these RC drilling results at Edjudina, which further confirms the
prospectivity of this project area, and anticipates that further RC drill testing will identify additional
high grade gold lodes in the project area, whilst further defining the existing known gold lode.
In addition Hawthorn is to begin development drilling, engineering and metallurgical testwork
designed to commence the conversion of its two most advanced gold projects – Trouser Legs –
Anglo Saxon and Deep South into mining operations.
At Trouser Legs – Anglo Saxon a 7500 metre drilling program designed to confirm pit boundaries
of the main deposit and quantify potential resources at satellite gold mineralised areas Coles and
Exile – has been approved by the West Australian Mines Department and will commence shortly.
Similarly at Deep South drilling programs designed to convert the near surface, high grade
mineralisation identified to date into resource categories is to commence shortly following Mine
Department approval. Mining at the adjacent Deep South Mine of Saracen Mineral Holdings
Limited, on what is believed to be the same mineralised horizon, has recently recommenced.
