Todd River Resources Limited Announces High Grade Rock Chip Results Confirm New Areas of Prospectivity at the MT Hardy Copper-Zinc Project
Todd River Resources Limited advised that high grade rock chip assay results have confirmed new areas of extensive prospectivity at its 100%-owned Mt Hardy Copper-Zinc Project in the Northern Territory. The Company plans to commence drilling these new target areas around the start of Second Quarter 2023 following completion of work on the wheatbelt projects in Western Australia and the receipt of statutory approvals. The systematic sampling of multiple prospective horizons has returned significant results from the Stardust- AB-Jack trend, the Lehmann trend and the Pacquiao area. Rock chip sampling followed up initial work completed earlier in the year that had defined broad surface geochemical base metal anomalies from the approximately 5,000 XRF soil samples taken on a grid pattern over amenable terrane. None of the new areas have been drilled at this point and all reflect new opportunities at Mt Hardy. Stardust-AB-Jack Trend: The Stardust-AB-Jack (SABJ) Trend covers a north west - south east trending strike extent of approximately 2.8Km and is located 1.5 kilometres to the north west of the previously published Hendrix Resource. The SABJ high grade results include 37.9% Cu, 17.8% Cu, and 16.8% Cu from gossanous zones up to 5m wide at surface. The dominantly malachite mineralisation is hosted in numerous sub-parallel brecciated quartz veins. In parts, significant Zn-Pb oxide mineralisation are associated with the quartz veins. Lehmann Trend: The Lehman Trend covers an extensive area to the north east of Hendrix that also trends NW-SE similarly to the SABJ Trend. The surface expression of the mineralisation at Lehmann is patchy, as it is at the base of a large hill and is obscured by scree. Results from the Lehmann Trend include 55.3% Pb+928 ppm Ag, 5.5% Cu+16.4% Pb+21% Zn, and 25.5% Cu+15.2% Zn. The massive Cu-Pb-Zn oxide mineralisation is hosted in a milled quartz breccia, which is footwall to an extensive silicified fault that can be traced for well over one kilometre. Pacquiao Area: The Pacquiao Area returned results including 19.6% Cu, 10.4% Cu, 6% Cu from a small areas of malachite mineralisation associated with minor breccia and faulting in psammite host rock. In addition to the prospectivity identified by recent rock chip sampling, previously announced areas of shallow base metal anomalism that were identified from bottom-of-hole sampling of historic drilling remain untested and are in areas of transported cover in the north of the project area. The areas of prospectivity under cover and drilling of these targets will also be completed as part of the extensive drilling program at Mt Hardy in Second Quarter 2023. Next Steps at Mt Hardy: It is expected that RC and aircore drilling at Mt Hardy will commence following the completion of exploration work at the Company's projects in the Western Australian wheatbelt around the end of March and the receipt of all statutory approvals for the drilling. Mt Hardy Project Background: Following the successful delination of mineralisation and the resource estimate at Hendrix in 2019, the Company's focus shifted to exploring additional prospects at Mt Hardy. Initially these included several isolated prospect areas where limited drilling was completed. Results from this drilling summarised in the Company's December 2019 Quarterly Activities Report released on 30 January, 2020. Highlights include: Gilly North Prospect: 10m @ 1% Cu, 0.4% Pb, 3.6% Zn and 24g/t Ag (5.0% combined base metals) from 5m, including: 7m @ 1.4% Cu, 0.6% Pb, 4.7% Zn and 36.4g/t Ag (6.7% combined BM) from 8m (MHRC0067). 9m @ 0.6% Cu, 0.1% Pb, 5.5% Zn and 7g/t Ag (6.2% combined base metals) from 36m, including: 7m @ 0.7% Cu, 0.1% Pb, 6.1% Zn and 8g/t Ag (6.9% combined BM) from 37m (MHRC0068); and 14m @ 1.1% Cu, 0.1% Pb, 3.4% Zn, 8.7g/t Ag (4.6% combined base metals) from 42m, including: 7m @ 1.4% Cu, 0.1% Pb, 6.3% Zn and 12.6g/t Ag (7.8% combined BM) from 46m (MHRC0069). Laver Prospect: 15m @ 0.4% Cu, 1.7% Pb, 5.4% Zn and 29g/t Ag (7.5% combined base metals) from 111m, including: 3m @ 0.6% Cu, 1.5% Pb, 11.7% Zn and 39.4g/t Ag (13.8% combined BM) from 111m (MHRC0091) and: 4m @ 0.9% Cu, 1.4% Pb, 2.9% Zn and 30g/t Ag (5.1% combined base metals) from 49m, including: 2m @ 1.3% Cu, 2.0% Pb, 4.5% Zn and 41.5g/t Ag (7.8% combined BM) from 50m (MHRC0090). Gilly Prospect: 7m @ 0.4% Cu, 0.3% Pb, 4.1% Zn and 15.4g/t Ag (4.8% combined base metals) from 23m, including: 4m @ 0.5% Cu, 0.6% Pb, 5.9% Zn and 7g/t Ag (7.0% combined base metals) from 23m, (MHRC0071). All Mineralisation noted to date at the Mt Hardy Project, including in drilling at Hendrix and other prospects and from surface sampling is hosted by the Lander Rock Beds Palaeoproterozoic metasediments of the Aileron Province of the Arunta Region, and is found within quartz veins and shear zones together with mineralised and altered Lander schists. Copper at is found in chalcopyrite in fresh rock (drill samples, >30 metres below surface) but all surface exposures are oxidised with malachite, azurite, and chrysocolla dominant. Lead and zinc occur as galena and sphalerite in fresh material and cerrusite and hemimorphite or smithsonite (respectively) in weathered surface samples.
