Maiden Ore Reserve for Anglo Saxon Gold Project

Hawthorn Resources Limited (ASX:HAW) is pleased to announce a maiden Ore Reserve for the Anglo Saxon Gold Project (“ASGP”) at the Trouser Legs JV ( HAW 70%, Gel Resources 30% ) of:

Probable Ore Reserve:

o 730,000 t at 2.66 g/t Au - 62,000 Ounces of Gold

This initial Ore Reserve is derived from the significantly increased Indicated Resource base contained in the updated Mineral Resource of:

Indicated & Inferred Resource:

o 4,132,000 t at 2.17 g/t Au - 288,500 Ounces of Gold

The announcement of this initial Ore Reserve highlights the robust economics and significant potential of the project.

Study highlights include:

Low C1 Cash Cost of $1,010 per ounce

  • Low capital expenditure requirement via Toll Treatment model

  • 18 month initial mine-life

  • Significant potential to increase Ore Reserves within the current resource base

  • Significant potential to upgrade and increase the current Mineral Resource which is open at depth

Updated Mineral Resource

Hawthorn Resources, as manager of the Trouser Legs Joint Venture in the Eastern Goldfields of Western Australia, has finalised the technical and economic assessment of the ASGP, de-risking the project and allowing finalisation of the project budget and schedule.

A revised Resource Model has been constructed by independent consultant’s BM Geological Services that better reflects the proposed mining methods and fleet likely to be used when mining commences.

This Mineral Resource estimate supersedes the previous estimation “ Anglo Saxon Indicated Mineral Resource Upgrade” announced in October of 2013 and completed by AMC Consultants .

The results of the updated resource estimate are tabulated in Table 1.

Table 1. ASGP Mineral Resource Estimate – 20 June 2017

Total Indicated Resource 0.5 2,107,000 2.15 145,600

Total Resources 2.0 1,459,000 4.21 197,700

Notes:

1 The Mineral Resource is reported in accordance with the 2012 Edition of the JORC Code

2 Contained metal is rounded to the nearest 100 oz

3 All resources have been rounded to the nearest 1,000 tonnes

4 COG is defined as cut-off grade

5 Top-cut of grade = 25g/t Au (oxide), 35g/t Au (transition) and 43 g/t Au (fresh)

6 The base of the Indicated Mineral Resource is 260m RL, approximately 125 m below surface

This new Mineral Resource estimate varies from the previous version in that:

  • Indicated Resource increased by 128% - inclusion of suitable Fresh ore blocks to a 125 m vertical depth.

  • Tonnage increased by 81% - internal dilution of ore blocks re-assessed to account for mining methodology proposed.

Open Pit Ore Reserve

An Ore Reserve estimate for the ASGP was undertaken utilising the updated Resource Model. Mining study inputs were updated to a pre-feasibly level, with independent mining consultant’s BM Mining delivering the Ore Reserve outlined in Table 2 below:

Table 2. ASGP Ore Reserve – 20 June 2017

Proven Ore Reserve 0 0 0
Probable Ore Reserve 730,000 2.66 62,000
Total Ore Reserve 730,000 2.66 62,000

The associated cashflow model delivers robust returns and early cashflow from near surface ore following mine and haul road construction. Contracts for haul road construction are to be awarded in the upcoming quarter with mining contracts to follow.

An additional 23,000 ounces of Indicated Mineral Resource contained within the pit optimisation have been excluded from the initial Open Pit Ore Reserve as preliminary underground mining studies suggest that improved economics may be achieved by utilising underground mining methods.

A preliminary stope optimisation utilising a conservative cutoff grade of 5g/t indicates that approximately 40,000 ounces of Indicated and Inferred Mineral Resource may be recoverable by a combination of long hole open stoping and overhand cut and fill mining. Work on a maiden Underground Ore Reserve will begin once open pit mining has commenced.

unit that dips west from 55 to 70 degrees and ranges from 20 to 100 m in width.
The mineralization is interpreted to dip from 38 to 75 degrees and occurs in a
number of fairly discrete packages, stacked above each other, broadly similar to a
ladder vein system. Gold mineralization appears to be related to thin quartz veins
which vary in thickness from 2 mm to 80 cm but occur in sub parallel groups. A
small pit mined during the mid to late 1980’s provides good exposure for mapping
mineralized veins. Many veins can be followed 30 to 50 m along strike with more
prominent veins being followed for up to 80m.
