Mandalay Resources Corporation Intercepts Gold At Two Highly Prospective Targets Near the Björkdal Mine, Sweden

Mandalay Resources Corporation announced successful results from its regional target testing drill campaigns approximately 6 km to the southwest of the Björkdal Mine. This release is the third and final in a series of updates on recent regional exploration programs at Björkdal. Program Highlights: Drilled 26 holes and 6,295 meters of diamond drilling to test high priority regional targets near the Björkdal Mine; Intercepted high-grade gold in multiple holes at Lapptjärn including one long interval; Returned encouraging results and high-grade gold assay from Granholm; and Identified semi-massive sulphide within Tarsnäs with elevated zinc and copper assays. Assay Highlights: Lapptjärn: 5.3 g/t gold over 7.05 m (ETW 5.40m) in LP-6; and 8.6 g/t gold over 0.70 m (ETW 0.35m) in LP-12. Granholm: 14.9 g/t gold over 0.5 m (ETW 0.38m) in GH-2. The Björkdal mine is located within the well-endowed Skellefteå mining district in Northern Sweden, which is characterized by its extensive mineralization and diverse geological features. The region hosts several world-class Volcanogenic Massive Sulphide ("VMS") and orogenic gold deposits, that have been actively mined for over a century. Geologically, the district spans a 120 by 30 km ore-bearing belt dominated by Paleoproterozoic volcanic rocks. This belt is part of a larger volcanic arc formation that emerged between the Bothnian basin to the south and the volcanic rocks of the Arvidsjaur group to the north. During 2022 and 2023, diamond drilling targeted four prospects located approximately 7 km southwest of the Björkdal mine site. The prospects Lapptjärn, Granholm, Tarsnäs and Nyholm are located along a 5 km long, NW-SE striking fold structure that is overprinted by later shear systems. In the southeast, this mineralized corridor terminates against the stratigraphic contact between the regional Skellefte and Vargfors Groups. The prospects are largely hosted within mafic to felsic volcanics of the Upper Skellefte Group, close to the contact with the Vargfors Group. The presence of marble lenses also indicate that they are located in the same stratigraphic interval as the Björkdal, Storheden and Norrberget deposits. In 2022 and 2023, Mandalay targeted Lapptjärn with two successive diamond drill campaigns, totaling 3,347 m across 13 drill holes, focusing on gold-in-till anomalies initially discovered by Terra Mining AB in 1986 ("Kalkberget project") and previously only tested with reconnaissance percussion drilling between 1986-1988. Mineralization at Lapptjärn is associated with structurally controlled lodes of disseminated arsenopyrite or irregular, arsenopyrite-bearing, Quartz-Carbonate veins. The mineralized zone is associated with silica-sericite-chlorite alteration and hosted within a folded sequence of felsic to mafic volcaniclastics belonging to the Skellefte Group, with interbedded marble lenses and graphitic shale. Several drill holes at Lapptjärn intercepted mineralized intervals, which appear to form a network of lodes over a strike length of 200 m, centered on high-grade intercepts in holes LP- 3 and LP-6. Although the high-grade intervals appear to have relatively limited strike and dip extent, the down-dip continuation of mineralization was confirmed by hole LP-12, leaving the system open at depth. During the summer of 2022, Mandalay Resources targeted Granholm with a diamond drill campaign totaling 1,016 m across 5 holes. The campaign aimed to verify and extend upon historical drilling from 1994-1995 by a joint venture between Boliden AB and COGEMA, which targeted an outcropping system of quartz veins associated with arsenopyrite, rare visible gold and zones of moderate to intense sericite alteration. The mineralization is hosted in folded and sheared rhyolitic to andesitic volcanic successions belonging to the Skellefte Group. Holes GH-1, GH-2 and GH-3 intercepted mineralized quartz veins, with the highest grades occurring in veins containing a core of massive arsenopyrite. Lower grades were observed in veins in which arsenopyrite typically occurs as a dissemination in the adjacent wall rock or along the contact of the vein. No visible gold was observed in drill core, however, grab samples from an outcropping Quartz vein include rare <1 mm grains of visible gold, demonstrating the potential for free-milling gold within the system. Holes GH-1 and GH-4 intercepted broad intervals of sericite schist that is crosscut by the later veins. The sericite schist itself is not mineralized but is indicative of a significant hydrothermal system within the prospect. Strong sericite alteration has been reported from the nearby Boliden deposit and the nature of the alteration system at Granholm is the subject of ongoing investigation. Mandalay targeted Tarsnäs with two successive drill campaigns in 2022 and 2023, totaling 1,493 m across 5 drill holes, focusing on an untested section of the Skellefte-Vargfors contact to the south of historical drill sites by Boliden AB and COGEMA in 1994-1995 and Eagle Mining AB in 2007-2008. These had previously intercepted auriferous arsenopyrite-bearing Quartz veins situated along the deformed and sericite-chlorite-silica altered contact between the Skellefte and Vargfors Groups. Nyholm is located approximately 8 km southwest of the Björkdal mine site, along a segment of the Skellefte-Vargfors contact which has historically been reported as hosting arsenopyrite- bearing quartz veins with anomalous gold. At Björkdal, all diamond drill core was logged and sampled by Björkdal geologists. Exploration drill hole samples were sent to CRS Laboratories Oy ("CRS") in Kempele, Finland for sample preparation and assaying.

Mandalay Resources Corporation Extends the Storheden Gold Deposit Adjacent to the Operating Bjorkdal Mine

Mandalay Resources Corporation announced that it has expanded the Storheden gold deposit, 600 meters (“m”) from the Björkdal mine, on-strike to over 1.6 kilometers (“km”) and at depth of approximate 200 m with high-grade gold intercepts. This press release is the first in a series of updates on their 2024 regional exploration progress at Björkdal. Program Highlights: Drilling confirms Storheden along strike to over 1.6 km; Doubled known system depth to ~200 m; Mineralization characterized by high grade gold intercepts (assay highlights below); • Structural setting akin to multi-million ounce Björkdal deposit located 600 m southwest; and A mining concession was secured in 2018 over a significant portion of the area. Assay Highlights: 70.2 g/t gold over 0.45 m (ETW 0.15 m) in SH-06 at 136 m; 39.7 g/t gold over 0.70 m (ETW 0.45 m) in SH-06 at 120 m; 7.3 g/t gold over 3.05 m (ETW 1.96 m) in SH-11 at 225 m; and 33.0 g/t gold over 0.40 m (ETW 0.26m) in SH-21 at 90 m. Regional Exploration Ramp-up at Björkdal During the summer seasons of 2022 and 2023 a total of 15,444 m, from 67 holes were drilled on prospective targets within the vicinity of the Björkdal mine (Figure 1). These targets were identified through analysis and interpretation of historical datasets and recent fieldwork conducted within Mandalay’s active exploration permits. They represent areas of high potential for further mineral discoveries and underscore our commitment to advancing exploration efforts in the region. Storheden Focus The Storheden deposit is located roughly 600 m to the Northeast of the Björkdal mine (Figure 2-3). Mineralization was first identified in the area from “top of bedrock” geochemical drilling in 1987. Subsequently, while percussion drilling had been undertaken on the target delineating an extensive mineral system, the active mine (Björkdal) has been the focus for exploration efforts leaving Storheden underexplored. In 2017, confirmation drilling and modelling undertaken by Mandalay lead to the granting of a mining concession in 2018 encompassing the confirmed mineralized zone. During 2023 a total of 5,149 m were drilled across 22 drillholes. Two separate targets were identified for drill testing. Depth extension and verification of system geometries; and Strike extension of the system to the southeast where the Storheden shear is interpreted to interact with the marble horizon. The primary aim of the 2023 deeps drilling campaign was to validate historical intercepts from percussion drilling and explore the down-dip extensions of the mineralized zone. Investigating the depth potential is important as the deposit is situated in part below the Bjorkdal tailings storage facility. Previous models for the Storheden deposit have been limited by the lack of diamond drill core, with most data derived from percussion drilling. However, oriented core obtained from drilling during 2023 has made it possible to verify and extend upon existing models, demonstrating the down-dip continuity of mineralized veins controlled by a moderately, N to NE-dipping system of shears that runs parallel to the Skellefte-Vargfors contact. Mineralized fluids appear to have utilized the rheological contact between relatively rigid volcanics of the Skellefte Group and weaker sedimentary sequences of the overlying Vargfors Group during deformation, in a similar manner to how shearing, fluid flow and mineralization in the Björkdal deposit is localized along the marble. Mineralization in the Björkdal deposit has significant vertical continuity, with known mineralization dipping to the north-westalong a slope distance of 1500 m, while remaining open at depth. The potential for similar down-dip continuity of mineralization in Storheden remains open, with 2023 drilling demonstrating that mineralization extends beneath shallow historical intercepts. Future programs will further test the down-dip potential of mineralization at Storheden, while extending the coverage of oriented drill core to verify historic data obtained from percussion drilling, particularly within the central section of the Storheden deposit. Gold mineralization occurs predominantly in quartz veins, ranging in thickness from less than a centimetre to more than several decimetres. Gold rich quartz veins are often associated with minor sulphides such as pyrrhotite, pyrite, chalcopyrite and arsenopyrite. In addition, scheelite, tsumoite and free gold are commonly observed in mineralised quartz veins. During 2023, a limited drill program totaling 1,116 m across 6 drill holes targeted the eastern extension of the marble horizon hosting the Björkdal deposit, which is also situated along the projected SE extension of the Storheden shear system (Figure 1). No drilling has previously targeted this area, however, limited historic drilling to the east has intercepted minor mineralized quartz veins. Despite its promising structural setting, the 2023 drilling showed that this area lacks the pervasive veining characterizing the Björkdal and Storheden deposits. This is tentatively attributed to a thickening of the marble towards the northern margin of the Björkdal dome that may have accommodated strain during deformation, inhibiting fracturing and veining within in its hanging and footwall. Drilling and Assaying At Björkdal, all diamond drill core was logged and sampled by Björkdal geologists. Exploration drill hole samples were sent to CRS Laboratories Oy (“CRS”) in Kempele, Finland for sample preparation and assaying. Assaying was primarily conducted utilizing the Pal1000 cyanide leaching processes. For sulphide -rich samples, Fire-Assaying conducted at MSALABS (FAS-221, 50 g charge) in Canada, following sample preparations (crushing, pulverizing) at CRS Kempele. Mandalay’s rigorous QA/QC program included the use of standard reference samples, blanks, duplicates, repeats, and internal laboratory quality assurance procedures.
