4010 DRILLINGDrilling soils in Chambe Basin using two hand-portable drills was carried outby MINDECO from August to October of 2011 but no details are currentlyavailable, and as no analyses have yet been made there is no new informationon the REE potential.11 SAMPLE PREPARATION, ANALYSES AND SECURITY(a) Sample preparation methods, quality control prior to analyses.The author was not involved in taking the samples listed in Tables 2 and 3,collected in Sept of 2010 and May of 2011, and has no information on theseaspects for these samples. However, it is thought samples were placed in plasticbags and submitted in this form to the analyzing laboratories.(b) Sample preparation and analysis procedures, laboratory.Samples collected by J. Ishikawa listed in Table 2 were split, pulverized andanalyzed for 14 REE and other elements (Ba, Co, Cr, Cs, Ga, Hf, Mo, Nb, Rb,Sn, Sr, Ta, Th, Tl, U, V, W, Zr) using method ME-MS81 at the North VancouverLaboratory of ALS-Chemex. This method involves fusing the sample to a glasswith Li tetraborate, dissolution in acids and analysis by ICP-MS and is intendedto break down refractory minerals and provide total contents of the elementsanalyzed. The results are listed in Table 4. The ALS-Chemex North Vancouverlab is accredited to ISO-9001 standard. At the laboratory of Nittetsu Mining R &D Centre in Japan splits of the samples were dried at 105˚ C for 24 hours,ground to 2 mm, and 50 g was leached in 500 mg of 2% ammonium sulphate for6 hours. The leach liquor was separated by centrifuge and analyzed by ICP-MS,with the results listed in Table 4.Samples listed in Table 3 collected by MINDECO/JOGMEC and theGeological Survey of Malawi were analyzed for REE by ICP-MS at TokyoUniversity. Samples of 15 g were leached in 150 ml solution of ammoniumsulphate.
