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.
The Company is running a very active drilling campaign at the property and the reader is encouraged to refer to ASX: AOP announcements for updates.
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 had now been defined over 300m along strike, approximately 250m vertical and up to 25m true width.
Ongoing drilling during 2018 & 2019 has shown that the discovery remains open in several directions and has established the potential for repeat and parallel mineralisation along the approximately 1km Rebecca prospect area.

Selected Jennifer Lode gold intercepts1 reported to date are shown below.
While much infill drilling and exploration remains to be carried out, it is clear that Jennifer Lode is a significant new gold discovery, and the Company will focus its activity into building its geological understanding and moving toward eventual resource calculation.
Drilling northward from Jennifer Lode during the second half of 2018 resulted in the delineation of the Laura and Jennifer NE 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.
Selected intercepts from these Lodes are shown below.
The Rebecca mineralised corridor remains open over its more than 1.3km 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 and Duke IP Gradient Array Chargeability Image
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

Duke Mineralised intercept in RCLR0193
The Duchess mineralised system comprises several disseminated sulphide lodes in a folded setting. Previous RC and diamond drilling have established that mineralisation corresponds with IP chargeability anomalies, the strike extensions of which are under-tested.
Apollo’s RC drilling results to date have shown potential to deliver multiple shallow west-dipping disseminated sulphide lode surfaces through a prospect area over 800m long and 400m wide. Significant gold results reported May 2019 included a best-ever gold intercept of 34m @ 1.88g/t Au, supported by 15m @ 1.95g/t Au*, defining a moderately west-dipping zone. Intercepts here are interpreted to be close to true width and are supported by historical1,2 results along strike including, 14m @ 1.21g/t Au and 11m @ 3.42g/t Au. The results outline a surface approximately 400m long that remains open to the north and down-dip.
Plan view all RC and diamond drilling at Duchess Prospect with selected historical1,2 intercepts. New drill collars shown as stars, and significant intercepts in yellow boxes. Interpreted sulphide lode surfaces (projected to base of oxidation) are shown as red lines. Note some intercepts may include composite samples, these will be resampled at 1m intervals.
Duchess Mineralised intercepts RCLR0337 & RCLR0339 Section 6637200N.
In a separate mineralised zone 400m to the NW, 30m @ 1.48g/t Au supported previous drilling results of 25m @ 1.51g/t Au up-dip. Other new intercepts along this zone include 11m @ 1.44g/t Au, 9m @ 1.53g/t Au, 5m @ 2.10g/t Au, and 7m @ 1.02g/t Au. These intercepts and historical drilling define mineralised west-dipping zones of disseminated sulphides extending over 350m strike.
Duchess Mineralised intercept in RCLR0324 Section 6637560N
Other significant new results include a strongly altered lode with 13m @ 1.46g/t Au that is interpreted to be close to true-width and is supported by 7m @ 2.95g/t Au in a historical up-dip intercept. More drilling is required to define the strike and dip extent of this surface.
