Pic: Ark Mines<\/p>\n<p>\u00a0<\/p>\n<h2><strong>Resource \u201cexceeded our expectations\u201d<\/strong><\/h2>\n<p>AHK has now brought the Sandy Mitchell project up to new heights with the definition of the maiden indicated resource, making it the first surface-expressed placer REE deposit with a JORC resource on the ASX.<\/p>\n<p>The company has also skipped past the usual step of first defining an inferred resource straight to the indicated stage, giving it a resource that supports mine planning right out of the gate.<\/p>\n<p>Furthermore, the reported monazite equivalent grade of 1,419ppm is expected to support strong project economics through simple low-cost downstream processing, with reference to current market prices for monazite concentrate.<\/p>\n<p>This is particularly true since valuable magnet REEs \u2013 neodymium, praseodymium, dysprosium and terbium \u2013 make up 24% of the total rare earth oxide (TREO) basket.<\/p>\n<p>There is also plenty of room for further growth as the resource takes up just 1.2% of the available anomaly area at Sandy Mitchell.<\/p>\n<p>\u201cThis maiden MRE has significantly exceeded our expectations. We have consistency in grade from surface to basement for a basket of high value minerals including combined heavy mineral grades of 13,450ppm,\u201d Ark Mines executive director Ben Emery said.<\/p>\n<p>\u201cThe commercialisation pathway for Sandy Mitchell is now more clearly defined, given the fact it is the simplest REE style of deposit to mine and beneficiate.<\/p>\n<p>\u201cImportantly, the MzEq grades of 1,419ppm are also indicative of potential commercial scale based on current market prices for monazite concentrate.<\/p>\n<p>\u201cIn addition, the MRE was achieved from a target drilling area which accounts for just 1.2% of the available anomaly area at Sandy Mitchell, providing plenty of scope for additional exploration upside.<\/p>\n<p>\u201cWe are also pleased to have the resource in an Indicated category, which bodes well for our upcoming pre-feasibility study and the mineral licence application.\u201d<\/p>\n<p>\u00a0<\/p>\n<h2><strong>More growth coming<\/strong><\/h2>\n<p>While the Sandy Mitchell resource is hugely positive, there is potential for growth in the coming months with the company looking to incorporate the results of its Stage 2 drill program into an updated resource estimate.<\/p>\n<p>The updated resource estimate will form part of AHK\u2019s forthcoming pre-feasibility study for the Sandy Mitchell project, which is scheduled to be completed before the end of the 2024 calendar year.<\/p>\n<p>\u00a0<\/p>\n\n<p><span class=\"mce_SELRES_start\">\ufeff<\/span>\u00a0<\/p>\n<p><em>At Stockhead we tell it like it is.
