The Deflector Region Operation is comprised the Deflector and Rothsay underground mines. Deflector The deposit type is classified as a hybrid Archean orogenic gold-copper deposit within the Gullewa greenstone sequence. The deposit comprises a series of en-echelon veins hosted within a flexure in the greenstone stratigraphy. Locally, the mineralisation is hosted in five main vein sets, the Western, Central, Da Vinci, Contact and Deflector South-West Lodes. Ongoing work at Deflector Southwest indicates that it is likely the continuous strike extension of Western domain. The main lodes are narrow, sub-parallel, fault-hosted, quartz-sulphide veins within a thick sequence of high-Mg basalt intruded by a series of dacitic, dolerite, and lamprophyric dykes. The mafic sequence is bound in the east by a volcanic-clastic unit, and in the west by an ultramafic unit. The metamorphic grade is defined as lower green-schist facies. The Deflector resource extents are 1,700m strike, 430m across strike and 630m below surface and open at depth. These extents host approximately 56 known ore zones (ore domains). The ore zones vary between 0.3 to 5m in width. Rothsay The Rothsay Gold Mine is located within the Warriedar Greenstone gold belt, an Archaean sequence of mafic, ultra-mafic, meta-volcanic and sedimentary rocks folded in an anticlinal formation which plunges and strikes to the north-northwest with steeply dipping limbs. The deposit is hosted in three discrete areas and within five in ........

Deflector
Mining at Deflector currently utilizes twin boom jumbos for ore development and longhole stoping between sill drives.

Underground
Ore lodes are accessed underground via a 5.3mW x 5.5mH, 1:7 decline centrally located along strike.

Level cross-cuts are mined to the east and west of the decline at 17 to 20m vertical intervals with ore development headings driven along strike to the lateral economic extents of lodes. Ore is mined using top-down mechanised open stoping methods on a shallow chevron retreat (when viewed in long section), leaving a variety of island, rib and sill pillars for stability. Localised portions of the upper mine will be extracted using a bottom-up mechanised open stoping method with cement and unconsolidated rock backfill.

All development has had 10%-15% overbreak applied, depending on drive type and location, as well as 100% mining recovery. All stoping has 0.5m hanging wall and 0.5m footwall dilution. The development overbreak estimation is based on 12 months actual data from July to April 2021. Stopes were designed as diluted shapes. Mining recovery is 95% for stopes with no island pillars, and 87.5% for stopes where an island pillar, 4.8mL x 6.0mH that will remain in-situ, is required. Minimum stope width has been applied based upon the lode being mined. Minimum mining widths are 2.5m for Western and Da Vinci Lodes, 2.3m for Central and Contact Lodes, 2.2 for Link Lode and 2.2 for Southwest Lodes. T ........
