Tarrina Resources Ltd (ASX:TR8) First Assays Conclude High-Grade Gold at Christmas Gift

5 May 2026

Price Sensitive Announcement $

Highlights:

— First assays received from hole CGDH001 drilled at Christmas Gift mine, NSW, confirm the highgrade nature of the historically mined ore with intersections up to 23.12 g/t Au.

— 31m total width of gold mineralisation intersected, either side of a 3m stope, confirming that significant widths and grades of gold remain.

— Intersections from CGDH001 include:
o 14.5m at 2.23 g/t Au from 58m, including 0.75m at 23.12 g/t Au from 71.75m (at the edge of a 3m stope from historical mining), and was followed by,

o 16.4m at 2.06 g/t Au from 75.6m, including2.64m at 10.49 g/t Au from 83m.

— Combined this is the widest and best gram-metre intersections recorded to date.

— Intersections are close to true widths due to the dip of the ore body and drill hole orientation.

— The width and grades of gold mineralisation intersected increase confidence in the historic intersections.

— The gold assays correlate with the visible zinc and copper mineralisation, confirming zinc and copper can be used as pathfinders for gold in future drilling and soil sampling.

— Assay results (Au, Zn and Cu) for the remaining holes and from the soil sampling program are all expected by the end of May 2026.

Overview:

Tarrina Resources Limited (ASX: TR8) (Tarrina or the Company) is pleased to announce the first gold assay results from its recently completed diamond drilling program at the Christmas Gift Gold Project in the Lachlan Fold Belt of southern NSW.

Historic mining and drilling have demonstrated the potential for a high-grade orogenic lode-style gold system with significant scope for extensions along strike and at depth1,2. This potential has been advanced with the first intersection of high-grade gold mineralisation, which confirms the widths and grades of the gold mined historically and validates the reported historic drill intersections.

Tarrina drilled CGDH001 to confirm results on a section through the Christmas Gift mine that included historic hole DDH0761 , which returned: 4m @ 3.9 g/t Au from 54m, 6m @ 0.9 g/t Au from 60m, 13m @ 13.1 g/t Au from 68m and 1m @ 1.37 g/t Au from 84m. CGDH001 intersected similar gold, sphalerite, chalcopyrite and pyrite mineralisation with silica and carbonate alteration to that in DDH076 from around 60m to 75m3.

The first gold assay results are from CGDH001, which was drilled into the mine area (Table 1)1,2. This hole intersected 31m of gold mineralisation, comprised of 14.5m at 2.23 g/t Au from 58m, including 0.75m at 23.12 g/t Au from 71.5m in the hanging wall of a 3m wide stope in the ore body and 16.4m at 2.06 g/t Au from 75.6m, including 2.64m at 10.49 g/t Au from 83m in the footwall of the stope (Figure 1, Figure 2 and Table 2).

These intersections are separated by a 3m void due to a stope where gold was mined historically, so does not include the high-grade core of the ore body (Figure 2). The total width of the gold mineralisation intersection if the stope is included is 34m in width (Figure 2), confirming that there is a significant amount of gold remaining from the historic mining. This is the widest intersection presently recorded at the project, including the historic drilling and in terms of gram-metres these intersections are the fifteenth and sixteenth highest out of the 228 intersections recorded at the project to date.

The drilling confirms the ore body dips around 45 degrees to the east, which means the intersected widths are close to true widths. The gold assays in CGDH001 spatially correlate with the visible zinc and copper mineralisation, which confirms that zinc and copper can be used as pathfinder metals for gold in future drilling and soil sampling2,3. The zinc and copper grades will be evaluated once the assays for these metals are returned by the end of May.

A complete list of the gold assays for CGDH001 are listed in the Christmas Gift Project Table 1 appendix and individual assays that comprise the intersections in Figure 1 and Figure 2.

Next Steps:

Planned activities at Christmas Gift include:

• Complete core logging and assaying of Phase 1 diamond core, with final assay results expected by the end of May.
• Complete low-level gold assaying of the auger soil samples and integrate with zinc and copper data to help prioritise exploration targeting, expected by the end of May.
• Update 2D and 3D geological models incorporating new drilling data.
• Field check anomalies mapped from the soil sampling program and plan follow-up drilling to test the anomalies for bedrock gold, zinc and copper mineralisation.
• Undertake follow-up RC drilling to infill and extend the new gold mineralisation between the Christmas Gift mine and the Cullinga Extended mine along strike and down dip
