Slide 4: Projects Overview
Projects Overview Yamarna – Mt Venn ▪ Located 25km west of the Gruyere gold project and 130km east of Laverton in WA ▪ Extensive copper-nickel-cobalt mineralisation outlined over several kms at Mt Venn complex ▪ RC and diamond drilling to infill and extend Mt Venn recently completed - further assays
Slide 5: Yamarna – Mt Venn Project
Yamarna – Mt Venn Project Mt Venn & Eastern Mafic Complex ▪ A large-scale copper-nickel-cobalt magmatic system Mt Venn ▪ Sulphide mineralisation discovered over Eastern Mafic several kms along the western margin of Mineralised the Mt Venn complex and remains open Trend in all directions ▪ Multiple,

Slide 7: Yamarna – Mt Venn Project – Where it Began…
Yamarna – Mt Venn Project Where it Began… ▪ Gold Road flew an airborne XTEM survey to map the Thatcher’s Soak paleochannel for processing water at Gruyere 15GYWB0004 ▪ Strong late-time EM conductor identified along the Mt Venn trend and away from the paleochannel, extending onto GBR tenement ▪ Gold
Slide 8: Yamarna – Mt Venn Project – Mt Venn Discovery
Yamarna – Mt Venn Project Mt Venn Discovery ▪ Two phases of RC (5,185m) and diamond (861m) drilling were completed at Mt Venn in late 2017 ▪ Multiple, broad lenses of shallow copper-nickel-cobalt mineralisation were intersected over several kms and open in all directions. Significant results include
Slide 9: Mt Venn Extensional drilling
Yamarna – Mt Venn Project Mt Venn Extensional drilling ▪ Recently completed 13 RC holes (2,554m) and four diamond holes (692m) at Mt Venn ▪ Drilling tested extensions to the central massive sulphide zone and the western contact between the mafic intrusion and footwall sediments that previously retur
Slide 10: Metallurgy Testwork
Yamarna – Mt Venn Project Metallurgy Testwork Ore ▪ Initial metallurgical trials have been completed on a composite sample from Mt Venn, testing Crush / metallurgical flowsheet options and ability to Grind produce separate copper, nickel and cobalt products. Preliminary results indicate: Copper Nick
Slide 11: Yamarna - Eastern Mafic Complex
Yamarna - Eastern Mafic Complex ▪ Identified in a gravity survey, the Eastern Mafic represents a large intrusive body prospective for copper, nickel and cobalt sulphide mineralisation ▪ Gravity and surface sampling indicates the Eastern Mafic complex is a very large circular body and appears to repr
Slide 12: Geochemistry supports bedrock conductors
Yamarna - Eastern Mafic Complex Geochemistry supports bedrock conductors ▪ The Eastern Mafic complex was targeted due to its geochemical signature that suggested an earlier stage of formation, meaning it is potentially closer to the source of the intrusion and therefore prospective for nickel sulphi
Slide 13: Moving Loop EM
Yamarna - Eastern Mafic Complex Moving Loop EM ▪ Detailed ground MLEM survey has commenced over the Eastern Mafic complex ▪ The MLEM survey commenced at the south of the airborne EM (AEM) conductor zone and has completed the first seven lines MLEM Completed MLEM Completed Gravity image (left) and la
Slide 14: Moving Loop EM (Ch 35)
