Rumble Resources Limited (ASX: RTR) has significantly extended the known mineralisation zone with the latest round of RC drilling results from the Tonka-Navajoh Prospect at the Earaheedy Project, located 140km northeast of Wiluna, Western Australia.
RC Drilling Results – Tonka-Navajoh Prospect
As part of the ongoing RC drilling programme on the Earaheedy Project, the results for 62 drill holes have been returned for the Tonka-Navajoh Prospect. The drilling involved further defining and extending the new Colorado Fault Zone on broad 200m section spacing.
Several traverses scoped a number of earlier ground gravity targets between the main Tonka and Navajoh zones targeting new fault zones.
Colorado Fault Zone (Tonka Prospect)
The Colorado Fault Zone mineralisation has been extended by 100% to a strike in excess of 2.5km (east-west trending) and is open to the east.
The latest intersections include:
• 25m @ 5.69% Zn + Pb from 215m (EHRC548), including 12m @ 9.72% Zn + Pb from 216 and a higher grade zone returning 5m @ 14.14% Zn + Pb from 216m
• 13m @ 4.64% Zn + Pb from 208 to EOH (EHRC544), including 4m @ 11.46% Zn + Pb from 215m, plus a shallow intercept of 3m @ 5.17% Zn + Pb from 22m
• 12m @ 2.55% Zn + Pb from 208m to EOH (EHRC547). The hole ended in high-grade mineralisation ie. 2m @ 8.20% Zn + Pb from 218m to EOH
• 11m @ 4.96% Zn+Pb from 138m (EHRC 506), including 8m @ 5.95% Zn + Pb from 139m
• 20m @2.54% Zn+Pb from 179m (EHRC 536) o including 5m @ 6.42% Zn + Pb from 179m
• 5m @ 5.75% Zn + Pb from 196m (EHRC541)
• 10m @ 3.43% Zn + Pb from 110m (EHRC516a)
Rumble previously reported the discovery of the Colorado Fault Zone (ASX Announcement – 26th May 2022 – Multiple New High-Grade Zn-Pb Zones Defined at Earaheedy) outlining significant widths of mineralisation and high-grade internal zones.
The new intercepts compliment previously reported high-grade intercepts on the Colorado Fault Zone which include:
• 73m @ 3.07% Zn + Pb (2.75% Zn, 0.32% Pb) from 106m (EHRC515), Including 13m @ 5.38% Zn + Pb (4.87% Zn, 0.51% Pb) from 108m o with 6m @ 6.70% Zn + Pb (6.13% Zn, 0.57% Pb) from 108m, Including 19m @ 3.48% Zn + Pb (3.08% Zn, 0.35% Pb) from 132m with 7m @ 4.50% Zn + Pb (4.03% Zn, 0.47% Pb) from 136m, Including 9m @ 3.56% Zn + Pb (3.18% Zn, 0.38% Pb) from 162m, with 2m @ 8.17% Zn + Pb (7.49% Zn, 0.68% Pb) from 162m
• 7m @ 10.71% Zn + Pb (8.52% Zn, 2.19% Pb) from 137m (EHRC518) o Including 3m @ 19.93% Zn + Pb from 138m
• 22m @ 4.27% Zn + Pb from 110m (EHRC399), Including 11m @ 5.82% Zn + Pb, from 121m
• 20m @ 4.27% Zn + Pb from 112m (EHRC398), Including 8m @ 6.75% Zn + Pb, from 117m
Of significance, on the PP Section, both EHRC544 and EHRC547 ended in mineralisation, with EHRC547 ending in high grade mineralisation – 2m @ 8.20% Zn + Pb.
Further drilling will be planned to define the limits to this high-grade mineralisation.
Next Steps at the Tonka-Navajoh Prospect
• A further 38 RC and diamond holes from the recent campaign at Tonka- Navajoh, which were planned to infill and extend the Colorado and Magazine Fault Zones remain to be reported
• Early interpretation of the preliminary Airborne Gravity Gradiometric (AGG) data has highlighted the Fault Zones as potentially a series of stacked high grade east-west mineralising structures within the extensive broad mineralised envelope (8km x 2km) at Tonka -Navajoh. Multiple new targets are being generated from this preliminary data and the Company is currently planning further RC/DDH drilling to test these areas in the near term.
• Sighter metallurgical test work to develop a preliminary flowsheet for the sulphide flotation concentrate is progressing well.
• An independent technical study to determine the optimum drill spacing for a maiden resource has commenced.
