43leach gives much lower values (see Table 13), is therefore considered unreliableand unsuitable for testing REE deposits of the ionic type and is not discussedfurther.2 Resampling at previously sampled sites. Four of the roadside sitessampled by Ishikawa (CHA-1, CHA-4, CHA-6, CHA-8) were relocated by handheldGPS and resampled at the same depths and from the same scrape as theoriginal samples. As it is conceivable that sampling only of roadside samplesmight bias results, perhaps reducing leachable REE by rain washing orincreasing the leachable REE by evaporation of REE-bearing ground water at thefree surface, at 2 sites (CHA-1, CHA8) samples were taken from new pits dugabout 10 m away from the road cuts. These results are reported in Table 10 and11 and compared with analyses of the original samples in Table 14.Considering that these samples include subsamples of the original samples,others re-collected at the same sites and nearby, and that analyses were done atseveral labs using different methods the agreement is reasonably good. It isconcluded that the results at least demonstrate that some samples contain asubstantial percentage (31 to 74% in Table 14 c) of easily leachable REE.However, the number of samples examined is very small and much more closespacedsampling and repeated reanalysis of a standard sample is needed toseparate analytical uncertainty from natural variability. Work on these aspects willbe part of the MINDECO program.3 Blank and standard. A barren quartz sand sample was submitted as ablank and a sample of REE standard SARF-1 was submitted as a standard.These results are shown in Table 10. Analysis of this standard gave resultswithin 2 std deviations except for La. The blank gave a total of 25 ppm, slightlyhigh, with the larger values for the more abundant REE (Ce, La, Nd, Y).Standards, blanks and duplicates analyzed by ALS Chemex as part of theirquality control gave acceptable results, although the standards used for theleaches generally had much lower concentrations than the samples.
