hydroxide (clay), carbonate and sulphate minerals; and anhydrous minerals such as quartz and feldspars, pyroxenes, as well as carbonates, sulphates and some hydrous minerals.<\/p>\n<p>GRL notes that the data found higher levels of REEs in highly weathered material that provide potential for low mining cost near-term extraction opportunities.<\/p>\n<p>Adding further interest, QEMSCAN (an automated mineralogical analysis technique) carried out by the Australian Nuclear Science and Technology Organisation (ANSTO) earlier this year on samples from the initial REE leachability testing indicates that most abundant REE-bearing minerals include lanthanite-Nd; cerite-Ce; and microcrystalline REEs.<\/p>\n<p>Liberation statistics indicate that most abundant REE-bearing minerals are moderately liberated, confirming the ready leachability of the kaolinite clay zone.<\/p>\n<p>Importantly, this unlocks additional development and processing opportunities for the company.<\/p>\n<p>\u201cTo have the Geological Survey of NSW select our project for spectral scanning using their HyLogger machine points to the value of this project, to not only GRL but also the state of NSW,\u201d managing director Jeneta Owens said.<\/p>\n<p>\u201cThe results of this QEMSCAN work combined with the initial leach testing, which indicated extremely high recovery rates of the most important four magnet REE minerals, really assist to understand the key characteristics of the deposit and start to define processing options to recover the REE\u2019s.<\/p>\n<p>\u201cThe company is now awaiting the receipt of the second round of metallurgical testing from ANSTO, where we have processed composite samples that are reflective of mining intervals.<\/p>\n<p>\u201cGetting results of the size fraction analysis work and different leaching conditions will provide information that can be directly fed into early-stage project flowsheet development.<\/p>\n<p>\u201cHaving a clay-hosted REE project in a geopolitically stable jurisdiction such as NSW, that is stacking up in terms of recovery of permanent magnet minerals is a major coup for Godolphin.\u201d<\/p>\n<p>\u00a0<\/p>\n<h2><strong>More to come<\/strong><\/h2>\n<p>GRL expects to shortly receive from ANSTO results from the second phase of metallurgical test work for Narraburra shortly.<\/p>\n<p>This includes desorption testing, a size fraction analysis and leach testing of composite samples under different conditions.<\/p>\n<p>The size fraction analysis is designed to determine if REE\u2019s are present in a particular size particle that may lead to easy screening and upgrading before leaching.<\/p>\n<p>Meanwhile, the leaching program has been designed to test for leachability down the weathered profile in composites that more represent mining intervals and across the defined resource area to better understand the metallurgy of the project and provide input into future mining studies.<\/p>\n<p>\u00a0<\/p>\n<p><em>This article was developed in collaboration with Godolphin Resources, a Stockhead advertiser at the time of publishing.<\/em><em>\u00a0<\/em><\/p>\n<p><em>This article does not constitute financial product advice.
