The area has characteristics which give strong evidence for the presence of specific types of mineral deposits. The assignment of high potential does not require that the specific mineral deposit types have already been identified in the area being assessed Moderate: An area is considered to have a moderate mineral resource potential if the available evidence indicates that there is a reasonable possibility of specific type(s) of mineral deposit(s) being present. There may or may not be evidence of mineral occurrences or deposits. The characteristics for the presence of specific types of mineral deposits are less clear Low: An area is considered to have a low mineral resource potential if there is a low possibility of specific types of mineral deposit(s) being present. Geological, geophysical and geochemical characteristics in such areas indicate that mineral concentrations are unlikely and evidence for specific mineral deposit models is lacking. The assignment of low potential requires positive knowledge and cannot be used as a valid description for areas where adequate data are lacking No: The term 'no' mineral resource potential can be used for specified types of mineral deposits in areas where there is a detailed understanding of the geological environment and geoscientific evidence indicates that such deposits are not present Unknown: If there are insufficient data to classify the areas as having high, moderate, low or no potential, then the mineral resource potential is unknown Certainty Score A: The available data are not adequate to determine the level of mineral resource potential. This level is used with an assignment of unknown mineral resource potential B: The available data are adequate to suggest the geological environment and the level of mineral resource potential, but either the evidence is insufficient to precisely establish the likelihood of resource occurrence or the occurrence and/or genetic models are not well enough known for predictive resource assessment C: The available data give a good indication of the geological environment and the level of mineral resource potential D: The available data clearly define the geological environment and the level of mineral resource potential NWQ COPPER PROJECT - INVESTOR PRESENTATION 11#12Big One in Focus | HD 2, 10, 11, 12 GEOLOGY2 The historic Big One Copper Mine's host rock comprises dolomitic feldspathic sandstone, siltstone (Lochness Formation), and quartzite (Whitworth Quartzite) Mineralisation includes supergene copper linked to a steeply dipping, northeast-trending fault zone, intruded by 2-5 m wide trachyte dykes with strong sericite alteration The altered hanging wall displays malachite, chalcocite, cuprite, with significant malachite staining along a 600 m strike length In 1997, -4,400t of supergene ore was mined with an average achieved grade of ~3.5% Cu CASTILLO COPPER CCZ Tenure Fault Prospect Mine Weberra Granite McNamara Group Surprise Creek Formation NWQ COPPER PROSPECTS HIGHLIGHTS Bigie Formation, Fiery Creek Volcanics Quilalar Formation Haslingden Group Mt Isa Group EPM 27440 PANCAKE THE CRESCENT MOUNT STORM THE WALL EPM 26574 .CROWBAR BIG ONE VALPARASIA EPM 26462 EPM 26513 EPM 26525 POM POM BOMB GEORGE BOOMERANG AMANDA ARYA BLACK MOUNTAIN ELDORADO SOUTH JOSEPHINE EPM 26513 MT OXIDE MINE EPM 26513 TORPEDO CREEK OLD MAN CREEK Mineral Occurrence 13 Primary: Cu | Secondary: NA | Type: Abandoned Mine [L. 180m x W. 20m D. 30m] Size: Small [500 - 50,000t] Possible occurrence of Cu, Co and Ag N CAPRICORN COPPER MINE NWQ COPPER PROJECT - INVESTOR PRESENTATION 12#13Big One in Focus TIMELINE . • ° 1970 Forsyth Minerals drill shallow drillholes. 1992 MIM Exploration conduct additional geochemical investigations. 1993 2020 2021 Savanah Resources conduct additional on ground studies, including rock chip sampling. .
