Rumble Resources Limited (ASX: RTR) has received further strong RC results from the Chinook West Extension drill campaign within the 100% owned Sweetwater tenement (E69/3787), located at the Earaheedy Project, 110km north of Wiluna, Western Australia.

The mineralization footprint defined by drilling of the Chinook Prospect is now over eight km in strike length and remains open along strike and down dip.

The company has now received the final drill programme results prior to the release of a maiden Mineral Resource Estimate (MRE) for Earaheedy, whilst also testing the potential western extension to the Chinook mineralization.

RC Drilling Results – Western Extension of Chinook Prospect – 100% RTR E69/3787

Infill and extensional RC drilling was completed on 200-400m spacings along and adjacent to the previously defined Chikamin Feeder Fault area and has highlighted strong continuity of higher-grade zones of mineralization. Results include:

  • 8m @ 3.78% Zn + Pb from 57m (EHRC677), including 3m @ 5.64% Zn + Pb from 57m
  • 7m @ 4.13% Zn + Pb from 53m (EHRC678), including 3m @ 7.00% Zn + Pb from 53m
  • 80m @ 1.32% Zn + Pb from 89m (EHRC688), including 9m @ 4.49% Zn + Pb from 103m
  • 15m @ 3.13% Zn + Pb from 127m (EHRC689), including 3m @ 6.33% Zn + Pb from 133m

Significant new Zn-Pb mineralisation includes:

  • 42m @ 1.65% Zn + Pb from 123m (EHRC664) Within the broad zone, higher-grade intercepts include 17m @ 2.82% Zn + Pb from 124m.

Some 800m northwest from EHRC664, strong mineralisation was returned:

  • 15m @ 2.35% Zn + Pb from 146m (EHRC 652), Inc 3m @ 4.50% Zn + Pb from 147m 54 holes were completed including broader spaced (400-800m) RC drilling designed to test the western extension of the Chinook Prospect within the Sweetwater tenement (E69/3787 – 100% Rumble) which successfully defined strong continuity of the mineralized Navajoh Unconformity while adding a further two km of strike to the large Chinook Zn – Pb mineralizing system.

The mineralization footprint defined by drilling of the Chinook Prospect is now over eight km in strike length and remains open along strike and down dip.

Geophysics – High-Grade Feeder Targeting

  • The strong correlation between high-grade feeder faults and gravity lows reported between Tonka and Navajoh Southeast has now be interpreted at Chinook, with Rumble finalising a targeting programme along the remaining 12km untested strike of the Sweetwater Trend

Copper Potential

  • Further significant copper mineralisation (19m @ 0.43% Cu from 204m) cross- cutting the dominant Zn-Pb mineralisation highlights the potential for a significant later copper dominated system within the Earaheedy Project

Next Steps at Earaheedy Project

Exploration

Rumble is currently finalising a targeting program aimed at identifying new potential feeder faults along the Sweetwater Trend within the 100% E69/3787

Drilling planned for 2023

Target newly interpreted high-grade feeder targets along the nine km Navajoh Southeast Trend – 100% E69/3787

Target any high-grade feeder targets identified along the Sweetwater Trend – 100% E69/3787

Continue to test and extend high-grade feeder structures within the Chinook, Tonka and Navajoh prospect areas – RTR 75% E69/3464

Maiden MRE

  • Rumble is working towards a maiden Mineral Resource Estimate for the Chinook and Tonka – Navajoh prospects

Metallurgical

  • Work to further improve the flotation performance following the exceptional sighter metallurgy reported on 17 November 2022.
  • Further variability work to confirm the simple and conventional flowsheet
  • Value adding beneficiation work (dense media separation and/or ore sorting) will commence once the required volumes of material have arrived from site and a suitable composite prepared.
