Rumble Resources Limited (ASX: RTR) has obtained significant new drilling results at the Chinook Zn-Pb-Ag-Cu Prospect located within the Earaheedy Project located 140km northeast of Wiluna, Western Australia.
Managing Director, Shane Sikora, said the results include the most recent hole within the newly discovered high grade Kalitan Feeder Zone.
“Following the Chinook Zn-Pb-Ag-Cu sulphide discovery in April 2021, broad spaced 500m x 100m scoping drilling defined a very large shallow flat lying 4.1km x 1.9km mineralised footprint that remains open in all directions,” Mr Sikora said.
“Later in 2021, Rumble commenced infill drilling on a 200m x 100m grid, with the impressive first assay results received from this program showcasing the potential to define a very large-scale open pit deposit with strong grade continuity and multiple large high-grade Zn-Pb core zones.
“Drill hole and geophysical analysis provided the exploration team with the essential technical understanding to discover the high grade Kalitan Feeder Zone at Chinook in December 2021.
“The 2022 RC/DD drilling programme will be the first to specifically define the open, 2.3km long Kalitan Feeder Zone, which continues to deliver high-grade Zn-Pb intercepts, and target other inferred high-grade Zn-Pb zones within feeder structures that are already delineated within and outside the existing Chinook mineralised footprint.
“Another recent exciting development is the interpretation of the airborne magnetics has shown the structural features that host the Chinook mineralisation including a multitude of inferred high-grade feeders and domal features, extend west of the current limit of the Chinook mineralisation into the 100% owned newly granted E69/3787, host to 15km’s of strike named the Sweetwater trend.
“Rumble is in advanced stages of completing heritage surveys along the Sweetwater trend and once completed, drilling is planned to rapidly extend and define the limits of the Chinook Zn-Pb-Ag-Cu deposit and target further large-scale discoveries.”
Kalitan Feeder Zone
The latest drill-hole (EHRC360) to target the northwest trending Kalitan Feeder Zone has delivered further high grades within a broad Zn-Pb intercept and has confirmed strike continuity of the higher Zn- Pb grades along the 2.3km long corridor that remains open along strike and at depth.
It is interpreted that seven drill-holes, including EHRC360, have either intersected the feeder zone or were near misses. EHRC360 lies between EHRC136 and EHRC370, which are 840m apart (see images 2 and 3). Drill hole EHRC360 returned a very broad mineralised zone of:
• 112m @ 1.51% Zn + Pb from 104m to 216m (end of hole) and contained a higher-grade core zone of: o 13m @ 6.97% Zn + Pb, 3 g/t Ag from 137m with a high-grade zone of:
▪ 6m @ 10.51% Zn + Pb (9.98% Zn, 0.53% Pb), 2.37 g/t Ag from 141m o End of hole mineralisation returned 4.58% Zn + Pb (215-216m EOH) Drill Hole Assay Intersection True Width
• EHRC360 lies 300m to the northwest of EHRC370. EHRC370 (previously reported) returned: o 51m @ 4.76% Zn + Pb, 5.81 g/t Ag from 82m which includes ▪ 20m @ 8.78% Zn + Pb, 11.65 g/t Ag from 98m with a higher-grade core zone of
• 8m @ 14.61% Zn + Pb, 17.7 g/t Ag from 104m from.
• EHRC360 also lies 540m southeast along strike from EHRC136. EHRC136 (previously reported) returned a very broad mineralised zone of 84m @ 1.84% Zn + Pb which includes:
• 37m @ 3.25% Zn + Pb, 7.18 g/t Ag from 196m with two zones ▪ 10m @ 6.57% Zn + Pb, 16.24 g/t Ag from 200m and ▪ 16m @ 2.54% Zn + Pb, 4.8 g/t Ag from 214m
• Within this zone, strong copper mineralisation was returned; 4m @ 1.54% Cu, 6.1% Zn + Pb, 23.6 g/t Ag from 204m.
The geology and style of mineralisation in EHRC360 is similar to that observed in previous holes EHRC136 and EHRC370.
Infill and Scoping Drill Holes
The latest results for the main Chinook Prospect area include both scoping and infill RC drilling and predominantly reports on the western extension and shallow up-dip zone close to the main salt lake (Lake Nabberu).
Intersections (>2% Zn + Pb) include:
• 17m @ 4.88% Zn + Pb, 3.33 g/t Ag from 72m (EHRC231)
• Inc 9m @ 6.22% Zn + Pb (5.55% Zn, 0.67% Pb) from 75m
• 17m @ 4.18% Zn + Pb, 5.12 g/t Ag from 110m (EHRC211)
• 29m @ 2.48% Zn + Pb, 3.58 g/t Ag from 122m (EHRC192B)
• 7m @ 4.04% Zn + Pb, 6.17 g/t Ag from 141m (EHRC347)
