OREAS Newsletter, February 2015

 

  • January saw the release of six new epithermal Ag-Cu-Au ore CRMs (OREAS 600 series) and two medium grade Mn ore CRMs (OREAS 171 & 172).
  • This month five new VMS Zn-Pb-Cu-Ag-Au ore CRMs have been released (OREAS 620 series - our catalogue has been updated to include these new CRMs).
  • The release of six new carbonatite-hosted REE ore CRMs is imminent.
  • A suite of four Cu-Au oxide ore CRMs will follow in early May.
  • Three greenstone-hosted Au ores will be available (3.0ppm, 3.5ppm and 6.6ppm Au) around April.
  • Merensky Reef PGE ore material is currently in transit to our premises to develop into a suite of CRMs (anticipated certification date Q3).
  • Another suite of IOCG CRMs will be developed in Q2 (for Q3 release) to replenish our existing stock (see OREAS 59a, 59b, 59c and 59d).

Many of these suites will come under the SuperCRM classification we introduced last year (i.e. incorporate full ICP-OES and ICP-MS suite certifications). Details of the suites mentioned above are shown below along with a brief description and their expected grades.

 

1. Five VMS Zn-Pb-Cu-Ag-Au CRMs (available now)

OREAS Newsletter, December 2014

 

Before the festive season begins six new epithermal Ag-Cu-Au ore CRMs (OREAS 600 series) and two medium grade Mn ore CRMs (OREAS 171 & 172) will be released. And in January 2015 five VMS Zn-Pb-Cu-Ag-Au ore CRMs will be released (OREAS 620 series) .

In February six carbonatite-hosted REE ore CRMs will be available and a new suite of Cu-Au oxide ore CRMs. Further down the track of 2015, three greenstone-hosted Au ores will be available and we hold high hopes of securing Merensky Reef PGE ore material to develop into CRMs. 

Many of these suites will come under the SuperCRM classification we introduced last year (i.e. incorporate full ICP-OES and ICP-MS suite certifications). The suites to be released are shown below along with a brief description and their expected grades.

 

1. Six high sulphidation epithermal Ag-Cu-Au CRMs

OREAS 600 to 605 are sourced from Evolution Mining’s new Mount Carlton operation in Queensland, Australia. Available as certified product December 2014. Target grades shown below.
