Stage 1 RC Drilling Programme Successfully Completed at the Munarra Gully Project - Amended

White Rose Cu - Au Mineralisation

• All drill-holes (four completed on the White Rose prospect) intercepted visible copper mineralisation beneath the shallow open pits.

• Visual inspection has confirmed both oxide and primary copper mineralisation is associated with a fine to medium grain pyroxenite (norite – hypersthene dominant) intrusive.

  • WRRC001 – 31 to 49m (oxide)

    • 18 metre section - minerals observed include malachite and chrysocolla. Visual estimate ranges from 2 to 8%.

  • WRRC002 – 75 to 85m (primary)

    - 10 metre section - minerals observed include chalcopyrite and bornite. Visual estimate ranges from 2 to 5% chalcopyrite. Bornite estimate 5 to 8% for interval 82 – 84m

• WRRC003 – 0 to 35m (oxide)

• 35 metre section – minerals include malachite and chrysocolla. Visual estimate ranges from 2 to 5%.

• WRRC004 – 45 to 75m (primary)

• 30 metre section – minerals include chalcopyrite and bornite. Visual estimate ranges from 2 to 5% for both minerals.

o Two RC drill sections were completed on 160m spacing.

Large First Order Conductor

Mr Steven Wood Company Secretary

• Two drill-holes tested a large (470m by 260m) conductor (plate) that lies 600m west of the White Rose Prospect.

• The first drill-hole (WRRC-005 – 200m depth) intercepted a late dolerite dyke (non-conductive) that deflected the hole thereby missing the target.

• The second drill-hole (WRRC-006 – 289m depth) was completed by a larger drill rig. Broad zones of dolerite and fine grain norite were logged, however, no conductive rocks were encountered. The source of the conductance has not been explained.

• Rumble has commissioned a downhole geophysical survey to further delineate the conductor.

• Proposed Stage 2 Drilling - Subject to the DHEM survey confirming and vectoring the main conductor, further RC drilling is planned.

Rumble Resources Ltd (ASX: RTR) (“Rumble” or “the Company”) is pleased to announce that Stage 1 RC drilling has successfully been completed at the Munarra Gully Cu-Au Project (“Munarra Gully”). The Munarra Gully project is located some 50km NNE of the town of Cue within the Murchison Goldfields.

The drilling programme consisted of seven (7) holes for 1149m.

White Rose Cu-Au Prospect

Four (4) drill-holes (WRRC-001 to WRRC-004) were design to test the primary zone below two small open cuts at the main White Rose Prospect. Two traverses, 160m apart were completed. Historic widespread copper and gold mineralisation in oxidised ultramafic/mafic had been exposed in the open cuts. Previous RAB drilling was confined to shallow oxide (vertical depth of 32m).

Significant copper mineralisation was observed in all four holes. Both oxide and primary copper mineralisation is present. Oxide mineralisation included chrysocolla and malachite. Primary mineralisation included chalcopyrite and bornite. The host is a fine to medium grain pyroxenite intrusion. The pyroxenite is essentially a norite (hypersthene dominant) that has intruded east-west cross cutting the regional geology which strikes northeast.

Visible copper minerals and their approximate intercepts include.

• WRRC001 – 31 to 49m (oxide)

• 18 metre section - minerals observed include malachite and chrysocolla. Visual estimate ranges from 2 to 8%.

• WRRC002 – 75 to 85m (primary)

  • 10 metre section - minerals observed include chalcopyrite and bornite. Visual estimate ranges from 2 to 5% chalcopyrite. Bornite estimate 5 to 8% for interval 82 – 84m

• WRRC003 – 0 to 35m (oxide)

  • 35 metre section – minerals include malachite and chrysocolla. Visual estimate ranges from 2 to 5%.

• WRRC004 – 45 to 75m (primary)

  • 30 metre section – minerals include chalcopyrite and bornite. Visual estimate ranges from 2 to 5% for chalcopyrite and bornite.

The visual observations referred to in this announcement are a preliminary technical assessment that have been completed by the Company’s Competent Person to provide some initial context to the exploration results. Further assay results are required before the Company will be in a position to provide quantifiable grades of mineralisation and a more detailed interpretation of the potential geological model at the Munarra Gully Project.

Large First Order Conductor

Two (2) holes were completed. The target is a large conductive plate (470m by 260m) that lies 600m west of the White Rose prospect.

The first hole (WRRC-005 – 200m depth) missed the target due to the presence of a late dolerite dyke. The hole lifted from 70° to 45° and the azimuth moved 20°.

The second hole (WRRC-006 – 289m depth) was completed by a larger capacity rig and was able to stay within tolerance with respect to intercepting the modelled conductor. Broad zones of dolerite and fine grain norite were intercepted, however, no conductive lithology (from geological logging) was intercepted. The conductor has not been explained.

A down-hole TEM (transient electromagnetic) survey has been commissioned to further delineate the conductor in hole WRRC-006. Subject to reinterpretation with the survey, further drilling is planned.
