Announcement

Thundelarra is pleased to report a new gold discovery at the Crown Prince prospect.

• Diamond hole TGGRCDD110 intersects new gold discovery • Multiple occurrences of free gold in quartz-carbonate veining • Geological logging recorded six such occurrences (figures 1-6) • This visible gold occurs across a 5.5m interval from 259.3m • Free gold in the primary zone is highly significant • Host veining noted over 15.7m from 251.7m • The board and our geological team are all very excited by the discovery of free gold in two of the holes drilled to date

Figure 1. Free gold at 259.30m (scale: mms). Figure 2. Free gold at 261.45m (scale: mms).

Thundelarra CEO Tony Lofthouse commented: “Finding visible free gold in fresh drill core from within the primary zone is uncommon and so this is highly significant for the potential of the Crown Prince prospect. The presence of visible free gold will generally indicate high gold grades, so the core will be cut, sampled and submitted for laboratory assays as soon as possible”.

These occurrences of visible gold reinforce the significance of the visible gold seen at 128.8m in hole TGGDD090 (ASX announcement of 01 November 2017). This is further evidence that primary gold mineralisation persists to depths well below the level of the historical workings at Crown Prince.

These findings validate our aggressive exploration approach, fully justifying our pursuit of the Crown Prince tenement. They augur well for the rest of the drilling campaign currently underway.

Figures 1 to 6 show photographs of the free gold observed in this drill hole and clearly show that the gold is separate from the sulphides. Figure 7 shows the 15.7m of drill core from 251.7m containing multiple quartz-carbonate veining that hosts the free gold mineralisation
