OREAS Custom CRM Quote Request Form

Number of CRMs required * [simple_tooltip content="1, 2, 3, etc? This in NOT the # of packets but # of distinct reference materials required (e.g. 1 x high grade CRM and 1 x low grade CRM)."][/simple_tooltip]

Weight of each source material [simple_tooltip content="Due to the scale of our facilities, the minimum preferred batch size is 100kg per CRM. ORE can blend to homogenise batch sizes from 10kg to 10,000kg."][/simple_tooltip]

Estimated grades of key analytes [simple_tooltip content="e.g. Cu = 1.5%, Au = 2-3ppm, etc..."][/simple_tooltip]

Source material to be supplied as [simple_tooltip content="Form of bulk sample material e.g. lump ore (5 -10 cm), split drill core, RC drill chips, pulp rejects etc. We prefer samples less than 150mm in size."][/simple_tooltip]

Packaging details [simple_tooltip content="ORE can package in single use units from 5 - 200g using laminated foil pouches or 500g - 2kg units in plastic jars."][/simple_tooltip]

List analytes to be certified and preferred assay methods [simple_tooltip content="e.g. Au by low level Fire Assay; Cu by ore grade 4-acid digest with ICP-OES or AAS finish, total sulphur by infrared combustion furnace (leco), etc."][/simple_tooltip]

Number of submissions (rounds) of samples to each laboratory [simple_tooltip content="e.g. 1 round of samples only or 2, 3, 4, etc rounds of samples submitted at weekly intervals. More rounds provide more robust control limits in terms of standard deviations, but add substantially to overall analytical costs.

More than one round of sample submissions to laboratories permits batch to batch bias to be monitored. A multi-round program can permit SD's to be calculated by the 'Pooled Repeatability method'."][/simple_tooltip]

Number of replicates (samples) in each batch [simple_tooltip content="Normally 5 or 6 samples are sent to each laboratory for single round submissions. This permits a measure of repeatability (precision) to be calculated and allows for analytical outlier detection. For multi-round submissions, usually 3 or 4 samples are used to limit costs but still permit a measure of repeatability to be calculated."][/simple_tooltip]

Check assaying of source materials required? If yes, please provide details of analytes and methods required [simple_tooltip content="Prior to commencement of the inter-laboratory round robin characterisation program we can check assay your source materials or candidate RMs. Check assaying is recommended if you are unsure of the grades of your materials as we may be able to 'adjust' grades of key analytes using ore, concentrate or barren waste rock."][/simple_tooltip]
