December 18, 2013 (Source: Krucible Metals Ltd.) — Coorabulka EPM Grant.

364_grant of coorabulka epm and rare earth r&d_Page_1_Image_0003Krucible’s directors are very pleased to announce the much awaited granting of Coorabulka EPM19286, the culmination of a two year application process.

The Company  applied  for  this  EPM in late 2011. Previous sampling by Krucible has returned strongly anomalous values in heavy and light rare earths (ASX announcement 11th January 2012 and ASX announcement 13th November 2012).

With  the  granting  of  this  EPM Krucible can now progress its exploration  plans for the tenement in 2014. Krucible’s plans include intensive gridded sampling to determine the extent of Rare Earth Element  (“REE”)  mineralisation below shallow cover. This will help define  future  drilling/costean targets.

Additional Ground Around Coorabulka

In addition Krucible has applied for selective   new  ground  adjacent  to and surrounding Coorabulka.

An application for EPMA 25126 “Valroy”  was previously  announced to the ASX on 30 January 2013 and is  anticipated  for  granting  in  early 2014.

Krucible is now able to report on the results of the new beneficiation technology which has been conducted on the concretionary samples from Coorabulka  in bench top leaching tests over the past year. As well as providing a more environmentally stable and more efficient process for beneficiating the REE, this metallurgical R&D will support a “means to market“ in our commercialisation plans for our rare earths,

The  first  leaching  trial  involving  Coorabulka   REE  rich  material  has  been  completed  by LogiCamms   Limited  (“LogiCamms”)   (ASX:LCM)   with  a  series  of  washes  currently  being completed   in  order  to  determine   the  actual   proportion   of  Rare  Earth  Elements   and Phosphates  leached  from  the  ore.   The  leaching  technology   used  for  this  first  trial  is LogiCamms’  proprietary process for the leaching of Phosphates  with simultaneous  leaching of  Rare  Earth  Elements.  The  trial  leach  utilised  approximately  80  kg  of  “nodules”  from Krucible’s  Coorabulka  lease.  These fist-sized  nodules  have  been leached  without  material size reduction.   The leaching  process  has been  conducted  over a period  of just  under  12 months and it is conducted in a low-intensity/low-energy input manner at ambient temperature.   These  leaching  conditions  lead  to low  super-saturation  levels  expected  to allow  the practical  recovery  of  Rare Earth Oxides  (“REO”)  by ion exchange  and/or  liquid- liquid  extraction.  By  contrast,  conventional  phosphoric  acid  plant  technology  (the  “wet process”) operates at temperatures significantly above ambient temperature and many compounds crystalize from solution given time and temperature reduction – an issue that complicates the potential for recovery of REO’s.

Laboratory  analyses  are  planned  to be  conducted  through  January  2014  to confirm  the extent of leaching that has been achieved during the leaching operations.   The trials should provide key information to allow the assessment of the economics of treating Coorabulka enrichment through simple mining, dry screening to recover nodules and hea p leaching and recovery of valuable constituents using LogiCamms’ proprietary technology.

The mineralogy of the Coorabulka nodules is advantageous for the heap leaching process because of the sub micron crystal size and high nodule porosity.   The nodules have a high strength and do not contain thorium.
