Golden Pig & Frasers Mine extension – change to Geo interp

• Northern strike extension of the Fraser Mine trending under the Lake Koorkoordine salt lake along with the continuation of the Golden Pig trend into the SW corner of the tenement package.

• The Fraser/Golden Pig mineralised complex can be traced north using both the aeromagnetic and existing drill data.

• Interpreted mineralised structures extend beneath recent alluvial paleochannel sediments which have hindered previous attempts at exploration. (targets are under a salt Lake)

• Much of the historic drilling has been shallow and ineffective given that a stripped profile exists directly beneath the paleochannel which limits gold dispersion from the mineralised structures.

• located between the Corinthian and Hopes Hill mines.

• Very strong auger geochemical gold anomalism has been defined over a strike length of 4.3km between, and along strike from, the Corinthian and Hopes Hill deposits.

• Drilling has confirmed the surface gold anomalism and intersected ore-grade mineralisation within the FSZ at numerous locations along this 4.3km trend.

• Drilling has identified numerous mineralised shoots along the FSZ with best gold-in-hole values including 66.0, 16.2, 11.2, 8.9 and 7.9 g/t Au.

Pilot north

• Targets HH01-HH02 cover a combined strike of 1.95 km of highly prospective stratigraphy and moderate gold anomalism. Outside of the two main areas of gold anomalism, drilling is considered to be largely ineffective comprising wide spaced, vertical and generally shallow drilling (see Section 16310N below). Historical drill evaluation of the FCSZ has only partially tested the FCSZ, further exploration comprising RAB and RC drilling is warranted.

• Two N-S structures evident in the magnetic imagery are considered analogues to the Pilot deposit and are rated highly in terms of exploration prospectively.

Northern Tenements

• Corinthia North Tenements

• The Corinthia North tenements cover 11.5 kilometers of the FCSZ. In addition to the strong prospectively of the entire strike length of the FCSZ, several structures, subparallel to the FCSZ have also been identified utilizing both geophysical and geochemical datasets.

• All structures are considered highly prospective for gold with strong auger geochemical gold anomalism and near surface drill intersections.

• A total of 12 discrete geophysical and/or geochemical targets have been identified (CN01-CN12).

• Target CN06 is a target with structural complexity/disruption of magnetic units evident in the aeromagnetic image and significant near surface drill intercepts including 3m @ 9.51g/t from 48 meters in drill hole SXR032 and 4m @ 5.5g/t from 18m in drill hole UNKUNK020.

• Target CN04 is a zone of interpreted magnetic destruction adjacent to the FCSZ which has recorded drill intercepts of 2m @ 7.72g/t from 53m in drill hole 88BSRC008 and 5m @ 2.0g/t from 23m in drill hole 88BSRC003.

Toll Treatment Optionality – short term cashflow for smaller reserves

• Toll Treatment mill at Marvel Loch within close trucking distance. ~ 30km

• Ore-grade drilling results have been achieved at numerous locations.

• Tolling agreement can bring in short term cashflow to fund extensive exploration.

• No Native Title exists over the project area. All tenements on Crown Reserve and Freehold Land. Allowing timely development of any economic ore identified

• Many known gold occurrences were overlooked by the previous large companies that owned them and have not been targeted for smaller scale deposits < 1M oz

• Significant value in smaller minable reserves given the availability of the Marvel Loch mill.

• Generate Cashflow to fund significant Drilling of entire Shear Zone

Production History – Southern Cross

• The first substantial gold production from the sequence was from the Copperhead Mine at Bullfinch in the 1950s.

• The majority of this production has come from within the greenstone sequences and ranges from Copperhead in the north to Bounty in the south and incorporates the Westonia deposits in the west.

• The northern half of FCSZ, Altan Rio’s tenure represents the majority of the mineralised belt extending south from the Copperhead mine site for ~28km to the town of Southern Cross.

• With Minjar Gold acquiring the Southern half along with much of the surrounding tenure and Marvel Loch mill for $330M in 2017.

• All major gold deposits in the northern greenstone belt are located on or immediately adjacent to major strike parallel structures.
