    Rumble Resources confirms major zinc-lead discovery at Earaheedy

    Rumble Resources Limited (ASX: RTR) announced that the assay results of the two RC drillholes fast-tracked at the Chinook Prospect within the Earaheedy Project in Western Australia has confirmed a major Zinc-Lead discovery.

    Standout results at the Chinook prospect included 34m @ 4.22% Zn + Pb from 66m – Vertical Hole (True Width) including 17m @ 6.65 % Zn + Pb from 73m, with higher grade core zone of 14m @ 5.02% Zn, 2.03% Pb (7.05% Zn + Pb) from 76m; and 21m @ 4.31% Zn + Pb from 61m – Vertical Hole (True Width) including 10m @ 5.02 % Zn + Pb from 67m.

    RTR said that the results have highlighted the potential for a very large-scale (Tier 1) Zinc-Lead System as the Chinook Prospect drilling has only tested 2km of the 45km of prospective mineralised strike underlining the potential to delineate multiple large tonnage, shallow (open pit) deposits throughout the Earaheedy Project.

    The company has completed the drilling of 33 reverse circulation (RC) holes across the Chinook and Magazine prospects within the Earaheedy Project with the total metreage being 3593m.

    Rumble’s Zn-Pb exploration target at the Earaheedy Project is between 40 to 100 million tonnes at a grade ranging between 3.5% Zn-Pb to 4.5% Zn-Pb. The company said that it intends to test the exploration target with drilling and this further drilling is expected to extend over approximately 12 months.

    Drilling at Earaheedy

    RTR had completed RC drilling at the Earaheedy project with the total metreage being 3593m for 33 holes. This included 26 holes for 2653m at the Chinook prospect and seven holes for 940m at the Magazine prospect.

    Drilling at Magazine was designed to test for potential strike vectors associated with mineralisation defined in 2020 by Rumble. EHRC034(2020) previously returned 12m @ 4.48% Zn + Pb from 88m announced 4th May 2020. The company said that the results are pending for all holes of Magazine prospect and are will be received in due course.

    Rumble had fast-tracked two drillholes (EHRC050 and EHRC044) at the Chinook prospect for multi-element assays.

    Major Zinc-Lead discovery at Chinook

    The company announced that the 26 drill holes out of 26 in Chinook prospect intersected visual Zn-Pb mineralisation. RTR said that the 2 holes fast tracked (EHRC050 and EHRC044) have been received confirming a Major Zinc-Lead Discovery. The assays for the remaining 24 RC drill holes at Chinook are pending.

    EHRC050

    Significant results included 34m @ 4.22% Zn + Pb from 66m – Vertical Hole (True Width) including 17m @ 6.65 % Zn + Pb from 73m with higher grade core zone of 14m @ 5.02% Zn, 2.03% Pb (7.05% Zn + Pb) from 76m.

    RC drill hole EHRC050 assay results are as shown below.

    EHRC044

    Results included 21m @ 4.31% Zn + Pb from 61m (True Width – 2% Pb + Zn cut-off) including 10m @ 5.02 % Zn + Pb from 67m.

    RC drill hole EHRC044 assay results are as shown below.

    Observations

    The company noted strong continuity of mineralisation, with EHRC050 and EHRC044 being 500m apart. RTR said that the mineralisation is pyrite-sphalerite-galena (sulphide) hosted in siltstone, shale, marl, and minor sandstone (basal unit of the Frere Iron Formation).

    The company said that the mineralisation is shallow, flat lying, dipping to the northeast – open pittable. RTR said that the ratio of Zn: Pb is approximately 3:1 with strongly anomalous silver associated with the mineralisation.

    Large Scale Zn-Pb-Ag ‘Tier 1’ deposit potential

    RTR said that all 26 holes at Chinook reported visible Zn + Pb mineralisation, aided by pXRF analysis. The company said that the RC drilling has defined the following mineralisation parameters: RC Drill Grid Design – 5 drill lines x 500m x 100m intersecting Zinc-Lead over 2km’s of strike and over 1.1km’s of width (limited to drilling grid) – Open in all directions; and RC Drilling results indicate true thickness is up to 34m – vertical holes.

    Rumble announced that the Chinook Prospect has the potential to be at the upper end of the existing exploration target for a large-scale, shallow and continuous open-pit deposit. The company noted that the prospective mineralised zone has over 45km of strike.

    Next steps

    The company said that further work would include Diamond drilling planned to follow up current RC drill program; and RC drilling programme to extend mineralisation along strike.
