Middle Island Resources Limited (ASX:MDI) New Large-Scale Gold Target Emerging At Zabrnjica Prospect

(MENAFN- ABN Newswire) New Large-Scale Gold Target Emerging at Zabrnjica Prospect, Priboj Project, Serbia
** New Large-Scale Gold Target Emerging at Zabrnjica Prospect** Sydney, Mar 12, 2026 AEST (ABN Newswire) - Middle Island Resources Limited (ASX:MDI ) continues to advance a significant new gold discovery opportunity at the Zabrnjica Prospect within its highly prospective Priboj Project in Serbia.
HIGHLIGHTS:

• A large, coherent gold system is emerging at the Zabrnjica Prospect, within an area previously subject to no recorded modern gold exploration.
• Broad, coherent gold-in-soil anomaly has been defined over a 600m-long, by up to 200m-wide area (+10ppb Au), hosted within highly altered, quartz-veined sediments.
• Rock chip sampling confirms bedrock gold mineralisation, with assay results up to 0.68g/t Au (in outcrop) and 1.91g/t Au (in float).
• Geological setting and alteration style are consistent with large-scale, replacementstyle gold systems (e.g.: Donlin Creek, Alaska).
• An initial five-hole reverse circulation (RC) drilling program is planned for the 2026 field season.
  MDI Chief Executive Officer, Peter Spiers commented:
  “We are pleased to announce a new exploration results from the Zabrnjica Prospect, within the Priboj Project, which represents another highly compelling new drill target within our Serbian portfolio. Results demonstrate a broad gold-in-soil anomalism with confirmed bedrock gold, within a favourable geological setting.
  These latest exploration results reinforce our view that this previously unexplored area has genuine potential to host a large-scale replacement-style gold system. These systems, which include intrusion-related deposits, often present as very large gold systems, such as the multi-millionounce Donlin Creek gold deposit in Alaska. With fieldwork set to recommence shortly, we look forward to systematically advancing Zabrnjica, including a five-hole RC drill program, alongside our exciting copper targets across the broader Priboj Project area. The Priboj Project remains largely underexplored, offering meaningful firstmover discovery potential within a highly prospective mineral belt. Our focus is on disciplined exploration designed to unlock value and position the Company for potentially transformative discoveries.”
  Ober Licence Soil Sampling Program
  Middle Island has received assay results for rock chip samples and an infill soil sampling program conducted within the Company’s 100%-owned Priboj Project area. The program was designed to target the discovery of sediment-hosted gold deposits within the Ober exploration licence,following the recognition of gold within a sediment package in the local area. This latest soil sampling program predominantly focussed on the Zabrnjica gold target area (Figure 1*).
  Zabrnjica Gold Target
  An infill soil sampling program, comprising 146 samples, was recently completed within the Zabrnjica target area. The program comprised eight north-south oriented sample lines and was designed to improve sample spacing over the immediate target area to a 100m x 100m staggered grid (Figure 1*).
  This program has reinforced the previously identified gold-in-soil anomalism at Zabrnjica, with new assay results up to 38ppb Au reported as part of the program, and has defined a central +10ppb gold anomaly that extends over an approximate 600m long, by up to 200m wide area (Figure 2*).
  Concurrent with the soil sampling, 14 additional rock chip samples were collected from the Zabrnjica area. Outcrop samples have returned up to 0.68g/t Au (K8833) and float samples up to 1.91g/t Au (K8856) in altered and variably quartz-veined sediments. The location of the new rock chip samples, together with previously reported rock chip results, is shown in Figure 2*.
  In light of the very positive results to date, the Company has now planned an initial five-hole reverse circulation (RC) drilling program at Zabrnjica. Commencement of RC drilling is subject to receipt of land access approval.
  Northern Gold Targets
  The Company also completed infill soil sampling programs across three areas in the northern half of the Ober licence (Figure 1*). The program, comprising 108 samples, was conducted to follow up generally discrete +10ppb Au gold-in-soil samples recorded in the initial 400m-spaced soil sample lines.
  Assay results from the Beli Potok target area (northern-most sample area) recorded several additional soil results in the range of 10ppb to 23ppb Au, and confirmed the presence of two zones of +10ppb gold-in-soil anomalism over approximate 400m long by up to 200m wide areas (Figure 4*).
  Additional rock chip samples collected from the Beli Potok area recorded assay results up to 0.26g/t Au (K8823). Follow-up prospect scale mapping and additional rock chip sampling are now proposed for this area.
  Next Steps
  The Company is very encouraged by the significant gold exploration results received to date from the Zabrnjica Prospect. An initial five-hole drilling program has been designed to test the highly altered gold mineralised sediments in this area. Drilling is scheduled for completion during the current field season, subject to land access approvals which are proceeding.
  In parallel with the above, the Company has planned additional copper-focussed exploration activities within the adjacent Priboj and Jermovac exploration licences (Figure 5*).
  Within the Priboj licence, an initial three-hole RC drilling program has been designed for the Jelaca Prospect targeting VMS-style copper mineralisation within a 900m long by up to 400m wide +200ppm copper-in-soil anomaly with outcropping rock chip samples assaying up to 10.3% Cu.
  Infill soil sampling is also proposed across the entire Jermovac exploration licence (Figure 5*).
  Initial wide-spaced soil lines (400m spacing) within the Jermovac licence have already returned multiple highly anomalous copper assay results, with individual assays up to 5,054ppm Cu.
  Commencement of further soil sampling within the Jermovac licence is subject to statutory renewal of the licence for its second three-year term.
