Mineralisation Envelope Increased By 44% To 4.1km Of Strike
Rumble Resources Limited (ASX: RTR) has obtained significant new assay results from the ongoing 40,000m drilling programme at the rapidly advancing Chinook Zinc-Lead (Zn-Pb) discovery at the Earaheedy Project, located approximately 110km north of Wiluna, Western Australia.
Results for 51 RC drill holes and two Sonic drill holes, part of the ongoing drill scoping of the Chinook Zn – Pb Prospect, has revealed further high-grade Zn-Pb intercepts and a 44% increase of the mineralised footprint.
Managing Director, Shane Sikora, said the scoping is designed to define the controls and limits of the mineralisation.
“The broad spaced scoping drilling continues to deliver at the Chinook Zn-Pb Prospect with an impressive 44% mineralisation envelope increase (from previous ASX announcement on 8 July 2021) to 4.1km x 1.9km. Mineralisation remains open in all directions,” he said.
“Another exciting development at the Chinook Prospect is that significant Zn-Pb mineralisation has been intercepted in numerous drill holes along the north-west corner, and within 50m of the main tenement (E69/3464) boundary which abuts Rumble’s (100%) pending application ELA69/3787.
“Based on the location and inferred strike of the mineralisation, Rumble has modelled that the Chinook mineralisation will extend west into ELA69/3787. ELA69/3787 already hosts the Sweetwater Zn-Pb Prospect which has historical Zn-Pb drill intercepts located over 12kms from Chinook, along the prospective unconformity, with no historical drilling ever completed between the two prospects.
“In addition to drilling activities at Chinook, the current drilling is also focused on defining the limits of Zn-Pb mineralization at the Navajoh and Magazine Prospects whilst looking for new discoveries along the 17km of mineralised strike so far delineated.
“Rumble is particularly excited about new prospects currently being drilled at the Earaheedy Project and looks forward to reporting on these developments as soon as results come to hand.
“Once the team completes the broad spaced drill scoping, drilling will focus on targeting the multiple feeder structures identified by the geophysics, which are interpreted to contain higher-grade Zn-Pb mineralisation.
“The Sonic Hole EHS002, a twin of EHRC044 reported a 26% increase in Zinc-Lead grade from previous RC assay (19m @ 6.1% Zn + Pb, 8.52 g/t Ag from 55m – True Width as vertical hole). This Sonic drilling is supporting the RC drilling results to date along with providing sample volume for initial metallurgical testing.
“Based on the drilling results to date, field observations and our developing understanding of the geology of this potential Tier 1 sediment hosted Zinc-Lead system, it is becoming very clear there is potential to delineate multiple shallow, flat lying open pittable Zn-Pb deposits throughout the 45km of strike at Earaheedy.
“To date we have only received and announced assays from approximately 9,000m of the 35,000m (~25%) drilling completed, largely due to the reported industry wide laboratory backlog. We believe the current extensive drill program will deliver further exciting developments and we look forward to reporting these results as they come to hand.”

Drilling Update – E69/3464
The current exploration drilling programme at Earaheedy has been expanded to 40,000m) and is designed to define the limits of the flat to gently northeast dipping Zn-Pb-Ag-(Mn) mineralisation associated with the unconformity that forms the hiatus between the overlying Palaeoproterozoic Frere Iron formation and the underlying Palaeoproterozoic Yelma Formation (lower section of the Tooloo Group) at the Chinook Prospect.
Drill scoping is also occurring at the Magazine and Navajoh Zn-Pb Prospects that lie some 7-12km southeast of the Chinook prospect and targeting new discoveries along 17km of open mineralised strike.
