Mineralisation is considered to be a mesothermal, vein and alteration style deposit similar to many other deposits in the Kalgoorlie district.

Regionally, Cannon is in the western part of the Bulong ultramafic complex in the Boorara Domain. The Bulong complex consists of 5km thick sequence of komatiitic lava flows made up of a thick serpentinised peridotite in the centre of the complex, flanked by thin spinifex-textured komatiitic flows at the top of the sequence. High-Mg basalts and interflow sediments are intercalated with the thin flow facies komatiites. Komatiitic basalt and high-Mg basalts have a variety of textures which include pillowed, pyroxene spinifex textured and variolitic textured.

A prominent, north – south trending, quartz vein cuts both high-MgO basalts and the Komatiites and extends for at least 1.5km to the south-south-west of Cannon and several smaller quartz veins sub- parallel to the main vein are also present. This quartz vein system has been the focus of past shallow prospecting and mining activities.

The Cannon mineralisation is structurally controlled and strikes north-easterly, dipping steeply to the north-west; higher grade zones within the mineralised envelope appear to have a steep northerly plunge. Gold-related alteration consists of biotite-calcite-chlorite-pyrite alteration with an inner core of albite-silica-carbonate-biotite-pyrite-gold replacement of the high Mg basalt and intermediate intrusions.

The Ore Reserve reflects the mining of the Cannon Mineral Resource via underground mining methods below the existing open pit. There is approximately three months of preproduction works including pit dewatering, mobilisation, and site establishment, followed by sixteen months of mining.

Operational activities shall be undertaken by a mining contractor with technical and managerial oversight provided by Horizon. Mining will be underground with access via a portal within the pit to develop the decline to the base of the mine, with lateral ore drives developed from the decline. The mining method will be a bottom-up method using longhole stoping with Cemented Rockfill (CRF). Ore and waste shall be loaded out by conventional diesel-powered Load-Haul-Dump (LHD) loaders and low profile trucks. Development undertaken with Jumbo Drills and stoping with Longhole drills.

Following pre-production activities, development occurs over a period of seven months, with stoping and backfilling operations commencing in month seven. Sufficient ore stockpiles for milling shall be built-up to enable processing to occur over months seven to seventeen with processing completed one month after mining is completed.

Stoping configurations are a bottom-up method, predominantly single-lift stoping (25m vertical interval). The single-lift stoping method involves establishing a rise to start the slot and then the stoping front is retreated along strike. The installation of h ........
