Rebecca Gold Project (Apollo 100%)*

The Rebecca Project comprises ~160km2 of tenure located approximately 145km east of Kalgoorlie, covering a greenstone belt on the eastern margin of the Norseman-Wiluna Greenstone Belt.  The belt lies at the southern end of the Laverton Tectonic Zone, a regionally important structural corridor that hosts multiple gold camps.

The project contains three advanced and growing gold discoveries – Rebecca (previously named Bombora), Duke, and Duchess (previously named Redskin), in which gold mineralisation is hosted by broad zones of disseminated sulphides in gneiss.  The boundaries of each system are only partially defined and offer potential for high-grade plunging positions internal to the zones.

On 10th February 2020, the Company announced a maiden resource estimate of 1.035m oz.

Rebecca Prospect & Jennifer Lode Discovery

Apollo’s drilling at the Rebecca Prospect during 2012 first demonstrated the potential for high grade gold shoots within the broad anomalous envelope at this prospect, with a reverse circulation intercept of 42m @ 7.75g/t Au1. In August 2017 inaugural core hole RHD04 returned outstanding gold intercepts, including 17.84 @ 15.95g/t Au and 49m @ 4.57g/t Au, corresponding to wide zones of strongly sulphidic alteration1. These two intercepts intersected the upper part of what is emerging as a significant body of gold mineralisation named the Jennifer Lode (previously ‘161 Lode’), a surface that has now been defined over 300m along strike, approximately 250m vertical and up to 25m true width.

 

Drilling northward from Jennifer Lode during the second half of 2018 resulted in the delineation of the Laura and Maddy Lodes, which have delivered wide zones of 1-3g/t Au grade mineralisation in west-dipping sheet like zones. Drilling during early 2019 has also located new mineralisation in an area some 200m to the south of Jennifer.

The pit contains a combined Indicated & Inferred Mineral Resource of 775,000oz gold of which 71% of material is at Indicated Mineral Resource status. All RC and/or diamond drill strings shown.

Yellow highlighted gold intercepts are selected drill holes completed after the Rebecca Mineral Resource estimation. 

The Rebecca mineralised corridor remains open over its more than 1.7km in strike, hosts multiple mineralised positions with excellent volume potential and compelling new drill targets continue to emerge.

Whilst the Rebecca Prospect remains the primary focus for drilling the Company is expanding exploration through the under-tested areas surrounding the Rebecca project.

Duke & Duchess

The Duke and Duchess prospects are located 4-5km to the south of Rebecca and have received historical RC and diamond drilling, but at a density unsuitable for the definition of individual Lode surfaces.

Disseminated sulphides in this area respond well to IP geophysical tools, and extensions to existing IP grids during early 2019 have delivered strong strike-extension targets.

Duchess

The Duchess mineralised centre occupies a broad area approximately 1200m long and 400m wide, located approximately 4km southwest of Rebecca (Figure 2). The area is characterised by widespread sub-horizontal layers of weakly mineralised (0.1-0.5g/t Au) material in the lower oxide profile, and multiple north tending & west-dipping disseminated sulphide structures in underlying fresh granodiorite and diorite gneiss.

The Duchess deposit is reported at Inferred Mineral Resource and totals 5.7Mt at 1.0g/t Au for 180,000oz at a 0.5g/t Au cut-off and constrained within a A$2,250 pit shell complex that extends over 900m strike, up to 500m width and to 190m depth. In places the Duchess optimised pit shells are limited by drilling data, an indication that continued step-out drilling may add additional material to the in-pit Mineral Resource inventory.

Duke

Gold mineralisation at Duke extends over at least 400m of strike and is hosted by a near-vertical disseminated sulphide lode with good down-dip continuity. Apollo’s limited RC drilling here successfully intersected wide zones of disseminated sulphide mineralisation and increased foliation and included intercepts of 35m @ 1.41g/t Au and 26m @ 1.60g/t Au1. Mineralisation remains open eastward, where historical drilling is orientated sub-parallel to strike.

The Company sees strong potential for higher-grade mineralisation along the mineralised surface, and plans infill drilling.

The Duke Mineral Resource is at Inferred status and totals 2.3Mt at 1.1g/t Au for 80,000oz at a 0.5g/t Au cut-off constrained within a single A$2,250 pit shell.
