Accent Resources NL Provide an Update on the Geometallurgical Drilling and Metallurgical Characterisa on Test Work Program over the Company's Magne Te Range Project
Accent Resources NL provided an update on the geometallurgical drilling and metallurgical characterisa on test work program over the company's Magne te Range Project. The Project is ideally located approximately 300 km by road from the Port of Geraldton in the Central Wheatbelt region of Western Australia and is immediately along strike to the northwest of Asia Iron Australia Pty Ltd.'s Extension Hill iron ore mine. The Project contains a magne te iron Mineral Resource of 523.3Mt grading 31.3% Fe. The Magne te Range magne te iron Mineral Resource is hosted within two dis nct banded iron forma on (BIF) units present along the strike length of the Magne te Range project - referred to as the Upper BIF and Lower BIF. The BIF units are stra graphically part of the Yaloginda Forma on, at the top of the Norie Group. The age of the BIF is es mated to be 2.8 Ga. The thicknesses of the BIF units vary along strike and down dip, likely represen ng a combina on of post deposi onal layer parallel folding and faul ng as well as syn-deposi onal so sediment slumping. The Upper and Lower BIF are separated by a non-magne c volcanic tuff unit which contains localised stringers of discon nuous BIF. The hangingwall and footwall to the BIF units is comprised of felsic, mafic, and ultramafic volcanics, with a mineral assemblage that reflects lower to upper amphibolite grade regional metamorphism. The overall package dips to the north at an average of 45 to 50 degrees. As previously announced, a geometallurgical diamond core drilling program commenced on 03 April 2024 and was completed on 20 June 2024. The program comprised a total of 18 drillholes which were designed as twins of historical reverse circulation percussion (RCP) and diamond core drillholes (DD) (Table 1). Twinning historical holes provided good control of the anticipated geology and mineralisation being targeted. The geometallurgical drilling program was designed to collect Mineral Resource representative diamond core for metallurgical characterisation. All diamond core was geologically and geotechnically logged on site, with digital photographs taken of each tray prior to dispatch to Bureau Veritas laboratory in Perth. Historical diamond hole MGD045 was retrieved from storage and incorporated into the metallurgical characterisation program. A program of downhole geophysical logging was completed in July 2024. The logging suite deployed comprised dual-spaced density, three arm calliper, magnetic susceptibility and televiewer (optical and acoustic) tools. Details of logged depths for each hole . Four of the drilled diamond core holes (MGD059, MGD060, MGD061 and MGD063) were shipped to China for geometallurgical test work by the Central South University as part of an engagement with Accent. Once all diamond cores had been inspected and nominal 2m head assay intervals identified, each hole was re- photographed dry and wet using a high-definition camera mounted on a purpose-built stand. One quarter core segments from each nominal 2m sample interval was submitted for assaying by XRF analysis of an extended iron ore suite of elements including Fe, SiO2, Al2O3, P, S, Mn, CaO, MgO, TiO2, K2O, V, Na2O, Cr2O3, Co, Ni, Cu, Zn, As, Ba, Cl, Pb, Sn, Sr, Zr, LOI 371, LOI 650 and LOI 1000. In addition to XRF chemical analysis Satmagan measurements of magnetic content were recorded. Final head grade XRF and Satmagan results have now been received for all samples, and significant drillhole intercepts from the 2024 geometallurgical drilling are included as . Significant intercepts are defined as samples with >25% Fe where the lithology code is BIF (banded iron formation), applying sulphur cut offs of <0.5% S for intercepts within the Upper BIF stratigraphic unit, and <0.2% S for intercepts within the Lower BIF stratigraphic unit.
