Kingston Resources Limited (ASX: KSN) (‘Kingston’ or ‘The Company’) is pleased to announce the recommencement of surface and underground drilling activities at its 100%-owned Mineral Hill Mine. The arrival of two drill rigs marks the commencement of a targeted investment in resource definition and discovery drilling, supporting Kingston’s growth strategy. Underground Drilling Program – Southern Ore Zone (SOZ) The underground diamond drill (DD) rig will first focus on the southern footwall mineralisation, the main production area with significant extension potential. Drilling will seek to define the extent of the near-mine discovery made in 2023 in surface hole KSNDDH017, which returned 12.5m @ 2.1% Cu, 3.7% Pb, 4.5% Zn 0.11g/t Au and 17g/t Ag (see ASX announcement on 23 November 2023). Additionally, there are numerous historical intersections peripheral to the main production zones that have never been followed up. All of this mineralisation exists outside of the current Mineral Resource Estimate for SOZ. Downhole electromagnetic geophysical surveys are planned to test for potential lode structures away from the drill holes. 24 November 2025 KINGSTONRESOURCES.COM.AU | ASX: KSN 2 Figure 1: Plan view of the designed extension drill holes at the Southern Ore Zone and Jack’s Hut.

A total of 15 RC holes are planned to test the coincident geochemical and near-surface Induced Polarisation (IP) anomalies over the northern part of the prospect reinforced by multiple anomalous intercepts in historical drilling. RC drilling is expected to be followed up with downhole electromagnetic geophysical tools. Following Bogong, six RC drill holes will be completed (1620m) at the Long Panel Prospect to test conicident IP, gravity and magnetic anomalies – key indications of near-surface mineralisation. Recent rock chip samples add additional weight of evidence to sub-surface mineralisation at Long Panel. High grade copper assays have been received from oxidized grab samples taken from mullock dumps adjacent to historical workings. Table 1: Long Panel rock chip results.

KINGSTONRESOURCES.COM.AU | ASX: KSN 5 IP and Gravity Survey at the Long Panel Prospect Kingston has commenced an IP survey over the southern end of the Long Panel prospect and will subsequently move to Yellow Mountain North. IP data was previously collected over the southern end of the Long Panel prospect, but the data is outdated, and newer collection technologies will improve targeting. IP is an electrical geophysical technique highly suited for identifying near-surface sulphide mineralisation. Gravity gradients identified in gravity surveys typically occur over known mineral deposits at Mineral Hill and so this technique is being extended to other deposits along the regional trend. Figure 5: Bogong, Long Panel and Yellow Mountain North location in relation to Mineral Hill processing plant. Kingston Resources Managing Director and CEO, Andrew Corbett said: “The recommencement of underground and surface drilling at Mineral Hill marks an exciting next step in Kingston’s growth strategy. Our focus is squarely on expanding the known resource base while testing highly prospective near-mine and regional targets. KINGSTONRESOURCES.COM.AU | ASX: KSN 6 The Southern Ore Zone continues to demonstrate excellent potential for further high- grade extensions, and with the addition of surface programs at Bogong and Long Panel, we are confident in the opportunity to deliver meaningful resource growth. These programs are designed not only to increase the scale of Mineral Hill’s operations but to extend mine life and enhance the project’s long-term value for shareholders. The arrival of two rigs on site underscores our commitment to unlocking the full potential of Mineral Hill as a cornerstone asset in Kingston’s portfolio.” Current Activities • Open pit gold and silver production • Underground diamond drilling at the Southern Ore Zone. • Induced Polarisation geophysics over the southern end of Long Panel and at Yellow Mountain North. • Surface RC drilling at the Bogong Prospect and Long Panel. • Underground development activities scheduled for the December quarter 2025. This program represents a major milestone in Kingston’s ongoing transformation of Mineral Hill into a long-life producing asset with material scale. By advancing both resource definition and regional exploration, the Company is well positioned to deliver continued growth in resource inventory, mine life, and shareholder value.

KINGSTONRESOURCES.COM.AU | ASX: KSN 17 Criteria JORC Code explanation Commentary Geology • Deposit type, geological setting and style of mineralisation. Mineral Hill is located on the southern and eastern margin of the Cobar Basin. Exploration tenements capture a NW trending corridor of prospective units that have been strongly deformed by compression and extension at the basin margin, coincident with the major regional structural feature called the Gilmore Suture. This suture is broadly the boundary between Siluro Devonian rocks to the west and Ordovician age rocks to the east. Structures that make up the Gilmore suture have sliced up and juxtaposed lithological units of different ages and origins and are an important feature in providing pathways for mineralising fluids. Later reactivation has also deformed, dismembered, and offset mineralisation and ore bodies. • EL 1999 and EL 8334 cover a NW-trending corridor - the Canbelego – Mineral Hill Belt. • The licenses host Ordovician Girilambone Group overlain by Early Devonian rocks and Quaternary cover. • The oldest rocks in the area are the Cambro-Ordovician Girilambone Groups which represent a sequence of metasediments and mafic volcanics. This stratigraphic unit is characterised by a high response in the magnetic data. • The Girilambone Group is overlain by the Mineral Hill Volcanics – a series of pyroclastic flows (ignimbrites, vitric and lapilli tuffs) with intercalated sediments of Silurian – Lower Devonian age. • The Mineral Hill Volcanics are overlain by units of the Majuba Volcanics (feldspar +/- quartz phyric, locally flow-banded rhyolitic to dacitic lavas), Devonian Talingaboolba Formation (a monotonous sequence of sandstones, siltstones and conglomerates which either unconformably overlie the Mineral Hill Volcanics or are over-thrust over the volcanics) and Myamley Sandstone. KINGSTONRESOURCES.COM.AU | ASX: KSN 18 Criteria JORC Code explanation Commentary • Sedimentary and volcanic units have been intruded by Yellow Mountain Granite – a foliated, medium-grained, equigranular and porphyritic biotite granite The Cobar Basin hosts a multitude of deposit styles that have the potential to occur within the tenement package. Mineral Hill provides a base line mineral system model for exploration in the district. More general Cobar style (Zn-Pg-Ag) volcanic hosted massive sulphides, Tritton style Cu-Ag-Au rich mineralisation, generic orogenic Au mineral systems models, and carbonate replacement provide alternate target types across EL8334 and EL1999. Mineral Hill Style Mineralisation Mineral Hill comprises polymetallic (Cu-Au to Cu-Pb-Zn-Ag-Au) vein and breccia, and shear hosted Au-Ag-Sb systems hosted entirely by the Late Silurian to Early Devonian Mineral Hill Volcanics, a pile of proximal rhyolitic volcaniclastic rocks with minor reworked volcaniclastic sedimentary rocks. The polymetallic mineralisation is structurally controlled and comprises lodes centred on hydrothermal breccia zones and veins within and adjacent to numerous faults, surrounded by a halo of quartz-sulphide vein stockwork mineralisation. Mineral Hill is made up of multiple separate mineralised structures that are characterised by specific economic mineral assemblages. Structures are broadly classified as Cu-Au or base metal dominant. • Jacks Hut trend (Ashes & Jacks Hut) is Cu-Au dominant in the north, and Pb-Zn dominant at Iodide in the south. Mineralised structures are not continuous, but the mineral system is contiguous. • Eastern Ore Zone is Cu-Au with some zones of very high-grade Au associated with veins with banded epithermal textures. KINGSTONRESOURCES.COM.AU | ASX: KSN 19 Criteria JORC Code explanation Commentary • Southern Ore Zone is a series of steep dipping structures that are anastomosing with link structures within a broader structural zone. Lodes on the west and at depth are Cu-Au dominant, with eastern loads being Pb-Zu +/-Cu-Au dominant. SOZ has a highly complex mineralisation history and paragenesis. • Red terror comprised Cu-Au lodes that have been thrust up and under Parker Hill Cu-Pb lodes that extend into the near surface Oxide profile. • Mineral Hill ‘Main Zone’ is classified as Volcanic hosted polymetallic vein and breccia systems with mineralised veins with colloform banded epithermal type textures. Pearse deposits are spatially separated from MH Main Zone and are classified as shear hosted orogenic Au-Ag-Sb deposits. Mineralisation is associated with pyrite-arsenopyrite within variably Qz-Se altered structures. All Siluro Devonian and Ordovician age units within the tenement package are prospective for mineralisation.
