Hill End NSW

The Hill End Project is located approximately 50 kilometres north of Bathurst in New South Wales and was the focus of intense and widespread goldmining during the nineteenth century.  The first gold rush in the 1850s mined out the rich surface gold and then a resurgence of activity occurred in the 1860s and 70s when very rich hardrock deposits were discovered in the Hawkins Hill, Reward, and Red Hill areas.  These were only mined to a shallow depth and Hill End Gold commenced work in the area in 1994 to explore beneath the old workings.  HEG has since built up its resources through surface and underground drilling and underground mining of 35,000 tonnes at 11g/t from the Reward deposit. 

This bulk sampling exercise in 2008-10 identified the geological, mining and processing parameters of the mineralisation as having good continuity over a kilometre scale, and that it is easily mined and processed.  The gold is quite coarse grained and high grade zones are predictable and continuous, and as an added bonus, simple gravity processing recovers approximately 95% of the gold.

The total Hill End Project mineral resources at November 2010 are 336,000 ounces gold including 900,000 tonnes at 8.6g/t in the Hawkins Hill – Reward deposit.

HEG has 100% benefical interest in all granted tenements, while the Hill End tenements encompassed by the previous EL2037 are subject to a 15% right to contribuute triggered by an 'economic feasibility study'.

Our focus in the Hill End Project area is to increase our resources, to identify the scale of the mineable resources along strike and at depth, and to bring a significant project into production.

Hawkins Hill – Reward Deposit

The Reward mineral resources stand at 246,800 ounces of gold based on underground drilling, development and mining of portions of the deposit over a strike length of 500 metres.

Gold Dore produced

 The Hawkins Hill - Reward deposit has been reopened by HEG and a modern exploration-scale mine established below the old workings. Previous production during the nineteenth century was more than 40,000 tonnes at 10 ounces per tonne from a network of mostly shallow workings, though some were sunk to 250m depth.  Surface and underground drilling, mapping and mining has now identified the mineralising structures associated with the very high grade gold mineralisation at Hawkins Hill – Reward and the system is interpreted to be over two kilometres in strike length and more than 300m deep.

The Reward mine and processing plant were established as a small scale bulk sampling project in 2008 and were upgraded to continuous operation in 2009.  The underground activities were suspended in 2010 pending the outcome of a scoping study into the development of a much larger project.

There is good potential to mine the multiple veins more productively and profitably with systematic and non-selective mechanised mining methods. Photometric ore sorting, tailings sizing and underground backfill disposal are providing encouraging value to the expansion model.  Additional resource extensions are expected along strike and at depth. The Company has commenced a scoping study to determine the potential and the economics of an expanded mining project.


Red Hill Deposit

The Red Hill deposit is located approximately four kilometres north of the Hawkins Hill – Reward deposit and has a resource of 849,300 tonnes at 3.3g/t gold for 89,200 contained ounces.

HEG has completed a detailed re-evaluation of the Red Hill deposit and previous exploration data using the sub-vertical structural model for gold mineralisation in the Hill End area.  The Red Hill mineralisation is hosted by more competent rock units than the mineralisation at Hawkins Hill – Reward and individual mineralised beds can be up to 30m thick as shown in figure below. The gold is introduced by narrow shear zones and fills extensive stockwork zones that plunge at a shallow angle to the north. Red Hill mineralisation has been drilled along a strike length of over one kilometre. A resource review is underway based on the new mineralisation model and has importantly indentified significant targets for future drilling.

Chambers Creek Area

Field work has commenced at Chambers Creek, which is located on the Hill End Anticline, eight kilometres south of the Reward Deposit. Historical mining at Chambers Creek occurred in 1872-1875.

Observations to date suggest that the Company’s reinterpreted model for gold mineralisation may also be applicable at Chambers Creek. Mapping to determine the structural controls fully is continuing at the site.
