Aldoro Resources Ltd ('Aldoro', 'The Company') (ASX: ARN) is pleased to provide an update on the latest niobium recovery testwork completed by Bureau Veritas Minerals, Perth.
KM004B - Metallurgical Process & Result
The initial beneficiation phase comprised of an open cycle of crushing, grinding, magnetic separation, acid wash and floatation. The sample KM004B (ASX:ARN 6/12/2023) was taken from the main body of the Kameelburg carbonatite and consisted of 100mm diameter core from a beforsite dyke. SEM analysis on the sample identified ferrocolumbite as the main niobium mineral. The sample was crushed and ground to 53um with 98% pass and washed in a weak acid before desliming, removing the minus 5um material, followed by floatation with selected reagents and collectors. The processes resulted in an upgrade of the head feed of 0.74% Nb2O5 to 5.5% Nb2O5, a multiple of 10.6 times with a 62.4% recovery rate of Nb2O5. The recovery rate and upgrade values are considered encouraging in the initial test phase. The forward process will focus on a finer grind and micro floatation to increase the grade and recovery further. The latest niobium recovery result provides ample confidence leading towards maiden drilling targeting rich niobium dykes at the Kameelburg Niobium-REE Project.
Advancing the Maiden Niobium Drilling at Kameelburg
The current campaign in prominent scale geological mapping and rock chip sampling will form the basis in targeting drill collars for the upcoming maiden diamond drilling programme. The initial diamond drilling programme will primarily focus on the Kameelburg niobium rich dykes, located at the south-west periphery of the large Kameelburg carbonatite. Track access clearance toward the niobium dykes, along with water bore drilling, has successfully been completed. At this stage, preparations for diamond drill rig and relevant personnel are advancing, with the initial drill programme targeted to commence at the end of Q3 subject to regulatory approvals.
