Sets using digestion by any combination of two, three or four acids (hydrochloric, nitric, hydrofluoric and perchloric) were excluded as method outliers based on statistical tests.
Sets using digestions by various combinations of acids were included only based on statistical tests. 
Statistical analysis of the data warrants classification as provisional despite only  6 or 7 sets of data.
Samples of  0.5 to 1 grams ignited for 0.5 to 2 hours at 900 to 1050°C are included only.
Sets using digestion by two acids (hydrochloric and nitric) or three acids (hydrochloric, nitric and hydrofluoric) were excluded as method outliers based on statistical tests.
Data fulfills the conditions for certified but the element was reclassified as provisional since the between-laboratories standard deviation is about 25% of the mean value.
Sets using digestion by two acids (hydrochloric and nitric) were excluded as method outliers based on statistical tests.
Sets using digestion by two acids (hydrochloric and nitric) or three acids (hydrochloric, nitric and hydrofluoric) were included only based on statistical tests.
No sets by digestion using two acids were received.
Data fulfills the conditions for certified but the element was reclassified as provisional since the between-laboratories standard deviation is 23% of the mean, and 3 sets of data have one significant figure
Sets by various methods using digestion with acids were received only, excluding outliers based on significant figures; data fulfilled the conditions for certification, but the element was re-classified as provisional since all of the accepted data have one significant figure.
Sets by fusion with lithium metaborate and sodium pyrosulphate are included only based on

    statistical tests.

Source
WPR-1a is a peridotite with rare earth and platinum group elements obtained from the Wellgreen property in the Yukon, Canada.  The raw material for WPR-1a was obtained from the same source as its predecessor, WPR-1.
Description
The mineral species include: serpentine (47.4%), talc (11.0%), diopside (9.8%), amphibole (8.7%), pyrrhotite (4.9%), magnetite (4.5%), ferrohornblende (3.5%), phlogopite (2.2%), chlorite (1.6%), pentlandite (1.4%), unnamed mineral: Fe-Cr-Cl (1.2%), calcite (0.9%), ilmenite (0.8%), chalcopyrite (0.7%), other (0.4%), pyrite (0.3%), wilkeite (0.3%), quartz (0.2%), titanite (0.2%), anorthite (0.1%), and albite (0.04%).
Intended use
WPR-1a is suitable for the analysis of rare earths, platinum and palladium and various elements at major, minor and trace levels in ores. Examples of intended use include quality control and method development.  A caution is advised for the use of WPR-1a for the quality control of data for gold.
Instructions for use
WPR-1a should be used “as is”, without drying. The contents of the bottle should be thoroughly mixed before taking samples. CanmetMINING is not responsible for changes occurring after shipment.
Handling instructions
Normal safety precautions for handling fine particulate matter are suggested, such as the use of safety glasses, breathing protection, gloves and a laboratory coat.
Method of preparation
The raw material was crushed, ground, sieved to remove the plus 75 µm fraction.  The recovery of the minus 75 µm fraction was 71%.  The product was blended, and then bottled in 400-gram units.  This is the only size that is available.
