Rumble Resources Limited (ASX: RTR) has intersected a new 2.2km high-grade feeder structure at the recently named the Chikamin Feeder Zone at its Earaheedy Project, 110km northeast of Wiluna, Western Australia.
The significant intersection was obtained in maiden RC drilling results along the Sweetwater Trend, along with the discovery of potentially two new parallel high-grade feeders within the 100% RTR (E69/3787) tenement.
The delineation of these zones has led to a further expansion of the Chinook Prospect’s mineralised footprint to over 5.5km x 2km at Earaheedy.
RC Drilling Results
High grade Zn-Pb mineralisation has been defined over a strike of 2.2km on 200m by 100m drill sections in association with a northwest-southeast trending structural zone, which is interpreted to be a mineralised feeder fault.
The newly named Chikamin Feeder Zone extends into Rumble’s 100% owned tenement (E69/3787) and occurs along the previously highlighted Sweetwater Trend. This new feeder zone is parallel to the earlier discovered Kalitan Feeder Zone, which lies 1.5km to the northeast. Some of the more significant RC results associated with the Chikamin Feeder included:
The mineralisation is broad (up to 50m true width) with high grade core intervals and is shallow dipping. The Chikamin Feeder Zone is open to the northwest and is likely associated with the original Chinook discovery intercepts (EHRC050 – 24m @ 5.57% Zn + Pb and EHRC044 – 21m @ 4.31% Zn + Pb) which lie to the southeast.
Further Potential Parallel Feeder Zones
Additional broad parallel intercepts of sulphide Zn-Pb mineralisation with high grade core zones have also been delineated approximately 300m and 600m west of the Chikamin Feeder Zone. Results include
The hig- grade mineralisation is sulphide and sphalerite (ZnS) dominant and is also strongly anomalous in Ag. These new zones hosted within the Navajoh Unconformity Unit are likely to further increase the Chinook mineralised footprint which now has a strike length of over 5.5km.
RC Drilling Results – Spur Feeder Zone
RC drilling results to the east of Chinook at the Spur Feeder Zone has shown strong continuity of high-grade mineralisation within broad intervals (60m wide) of Zn-Pb sulphide mineralisation. The Spur Zone is inferred to trend east-west and is contiguous with the Kalitan Feeder Zone. Mineralisation remains open to the east and at depth.
