Solstice Minerals Limited reported a maiden JORC Mineral Resource Estimate (MRE) at the 80% owned Hobbes Gold Project located 5km to the southwest of Northern Star's Porphyry mining centre. Solstice advised that the Company's recent exploration campaigns have delivered an important milestone at the Hobbes Gold Project, located 150km northeast of Kalgoorlie, with a maiden MRE. Independently modelled, the MRE is 4.6 million tonnes at 1.2g/t Au for 177,000 ounces reported in accordance with JORC 2012.

Importantly, the Company has considered high- level economic parameters and has reported the MRE at a 0.6g/t Au cut-off, and only those gold ounces constrained within an AUD 2,500/oz optimised pit shell. The Hobbes MRE has supergene and fresh rock components. Supergene gold mineralisation forms a flat-lying blanket with broader dimensions of up to 1km in strike, 400m width and is in places up to 30m thick.

Optimisation using a $2,500/oz gold price produced a pit shell that incorporates a significant area of supergene mineralisation as well as the core of an underlying primary gold system. The pit has a maximum depth of 160m from surface, and the combination of supergene and fresh rock material offers potential for a modest strip ratio in a commercial development. Fresh rock gold mineralisation sits in multiple west-dipping lodes that initiate from and are controlled by local cross-faulting.

The primary gold system remains open at depth. The maiden Hobbes MRE was commissioned following Solstice's successful 2022 exploration campaigns at the Project. Solstice continued the work of previous explorers Newcrest Operations Ltd. (Newcrest), Renaissance Minerals Ltd. (Renaissance) and OreCorp Ltd. (OreCorp), completing an infill and step-out RC and DD program comprising 27 RC holes for 5,884m, and ten DD holes for 2,500m on five traverses covering 300m of strike.

A reliable geological model based on aeromagnetic interpretation, logging and litho-geochemistry was developed. This was used to model fresh rock lode geometries in the MRE and the improved model can now be applied to identify priority step-out targets. Mineral Resource Estimate: Project Location: The Hobbes exploration licence (E31/1117) is situated in the core of the Company's extensive Yarri landholdings and covers an area of 95km2 approximately 5km west of Northern Star Resources' Porphyry Mining Centre.

Nexus Minerals' emerging Crusader-Templar gold deposit is located approximately 10km to the southeast. Northern Star operates several mines in the Porphyry area and is hauling material to its Carosue Dam operations located 36km to the south. Project Geology: The Yarri Project is located on the eastern margin of the regional Keith-Kilkenny Tectonic Zone (KKTZ), a proven gold corridor that includes the >3moz Carosue Dam gold camp.

The KKTZ is dominated by intermediate volcanic, felsic volcanic and sedimentary rocks often overlain by younger cover material. Most of the gold mineralisation in the Hobbes area is hosted by structures cutting granitic or syenitic intrusives, as best seen at the nearby Porphyry-Wallbrook gold system and on- tenure at Quandong. Intrusive-hosted mineralisation is often associated with a distinctive pink hematite-pyrite style of alteration.

Gold mineralisation in intermediate volcanic or metasedimentary rocks is vein related, but often with a direct or spatial association with intrusives. Hobbes itself is hosted within volcaniclastic, andesite and carbonate altered mafic rocks, but there are altered molybdenum +/- copper bearing intrusive rocks nearby. Hobbes Local Geology: The Hobbes MRE is located under an area of transported cover that includespaleochannel sediments and was discovered and delineated by a combination of aircore then RC and DD drilling.

There is no outcrop in the immediate prospect area so geological interpretation is based on drillhole logging and litho-geochemical data collected from recent and historical drilling. Hobbes gold mineralisation is interpreted to be located within a north-northwest trending package of intermediate volcanic rocks sandwiched between a basalt hanging wall and rhyodacitic volcanic to volcaniclastic footwall package. The stratigraphic sequence dips steeply to the west and is offset by a series of broadly northeast trending, apparently right lateral strike-slip faults, and a west- northwest striking left lateral strike slip fault.

Intrusive units include syenite sills and dykes, and thin mafic sills.Two of the northeast trending faults, the North Boundary Fault (NBF) and subparallel South Boundary Fault (SBF) enclose a broader, strongly altered and demagnetised zone. The NBF and the west-northwest striking fault appear to be an important control on higher grade primary gold mineralisation. Hobbes Gold Mineralisation: The Hobbes MRE has two components, a flat-lying blanket of supergene gold mineralisation that sits in the saprolite profile below transported material and covers an area of up to 1km in strike, 400m width and is up to 30m thick.

The supergene mineralisation overlies and is sourced from a smaller but significant fresh rock system defined by multiple west-dipping lodes controlled by local cross-faulting.
