The 100% owned Boorara Gold Project is 10 kilometres east of Kalgoorlie’s Super Pit gold mine located on the eastern edge of the city of Kalgoorlie-Boulder, Western Australia. The Boorara Project contains over 1.5 kilometres of gold mineralisation striking north-west at 330 degrees. The project is divided into three project areas, namely Royal (Southern), Crown Jewel (Central) and Regal (Northern) deposits.

The 100% owned Boorara Gold Project is 10 kilometres east of Kalgoorlie’s Super Pit gold mine located on the eastern edge of the city of Kalgoorlie-Boulder, Western Australia. The Boorara Project contains over 1.5 kilometres of gold mineralisation striking north-west at 330 degrees. The project is divided into three project areas, namely Royal (Southern), Crown Jewel (Central) and Regal (Northern) deposits.

Gold mineralisation is hosted in a series of stacked quartz vein arrays that dip at 40-45° to the northwest. The true thickness of the arrays is up to 50 metres vertical and they are hosted within the quartz dolerite which dips at 73° to the northeast. The mineralised dolerite has a true width of up to 40 metres based on a review of all historic drilling and drilling completed more recently by MacPhersons Resources. Within the mineralised Boorara dolerite high grade localised ore shoots consist of vein arrays up to 20 metres in width. The increased width of the mineralised dolerite indicates that this is potentially a larger mineralised system.

The Boorara deposit has a JORC 2012 Mineral Resource Estimate of:

16.45 Mt at 0.96 g/t gold for 507,000 oz of gold at a 0.5 g/t lower cut-off grade.

The area has had several phases of mining activities including recent small scale trial mining at the Boorara deposit which was completed in 2016. The trial pit was completed within budget and 30,000 dry tonnes of ore was treated at the FMR Greenfields treatment plant at Coolgardie at a head grade of 1.73 g/t which produced 1,525 oz of gold.

The trial open pit was excavated to a final depth of 20 metres. For the first time the orebody was exposed and quartz veining could be measured. A structural mapping project was completed which involved mapping within the trial pit that resulted in a new geological model for the Boorara Gold Project.

The Mineral Resource estimate for Boorara is currently being reviewed with the aim to establish a solid resource base to undertake further mining studies and convert to a maiden Ore Reserve to underpin production for a standalone processing facility at Boorara in line with Horizon’s production growth plans.
