Existing Lead/Zinc Mineralisation at Explorer 108 a potential feed source for the Rover 1 infrastructure

Extensional Drill Hole NR108D049-1 drilled by Castile in 2021 returned sections of high grade zinc and lead with trace copper from a massive 145m mineralised interval

Highlights from Hole NR108D049-1 include the following intercepts:

145m @ 1.6% Zn and 0.9% Pb with 9.3g/t Ag and 0.6g/t Au from 485m downhole.

inc 4.9m @ 5.7% Zn and 3.1% Pb with 57.8g/t Ag, 0.1% Cu and 7.6g/t Au from 493.1m downhole.

inc 7.1m @ 5.7% Zn and 3.4% Pb with 12.9g/t Ag, 0.1% Cu and 0.7g/t Au from 558.9m downhole.

inc 2.2m @ 12.6% Zn and 3% Pb with 17.3g/t Ag, 0.1% Cu and 0.5g/t Au from 581.35m downhole.

inc 6m @ 2.4% Zn and 1% Pb with 6.5g/t Ag and 0.2g/t Au from 607m downhole.

The Explorer 108 resource is comprised of the following:

• Indicated Resource of 8.438Mt @ 3.41% Zn, 2.05% Pb, 14.32g/t Ag; and

• • Inferred Resource of 3.43Mt @ 2.81% Zn, 1.88% Pb, 3.32% Ag .

Warumpi Project – Potential for Significant Base Metals Mineralisation

Highly prospective grass-roots exploration project located approximately 300 km west of Alice Springs in the West Arunta region of the Northern Territory.

7.7% Cu, 3.2% Zn and 90.6g/t Ag 4.8% Cu, 3.0% Zn and 182 g/t Ag 3.7% Cu, 1.3% Zn and 83.8g/t Ag 2.4% Cu, 1.6% Zn and 9.9% Cu, 4.7% Zn and 120 g/t Ag 85.4g/t Ag 4.6% Cu, 8.6% Zn and 24.9 g/t Ag

The age of the Warumpi Province (1690–1610 Ma) is a particularly significant epoch as the stratigraphy of this period hosts similar world-class stratabound Pb-Zn-Ag mineralisations.

The project area includes a significant proportion of tenure that has only had cursory exploration completed on it in the past.

Favorable structures are evident in aeromagnetic images as well as anomalies in various geophysical survey methods.

The Company refers to the exploration results contained in this presentation as sourced its Prospectus dated 3 December 2019 and released on the ASX on 12 February 2020,
