Abstract

Sample 1110C was sent to CODES Analytical Laboratories for mounting and analysis to determine quantitative mineralogy with a focus on Ag- and Pb-bearing minerals, and to determine Pb and Ag contents in all mineral phases by laser ablation ICPMS. Two identical ~200g bags of sample were received. One bag was used. A representative split of the sample was gently crushed and sieved to <500um grain size, mixed with epoxy resin, placed into 2.5cm mount. Upon hardening, sample was sectioned to expose coarse-fine profile, remounted in epoxy, and polished for analysis. Two mounts (S1 and S2) were prepared in this way. The mounted samples were analysed by SEM to determine mineral proportions and to perform Mineral Liberation Analysis for Pb- and Ag-rich minerals. The same sample was then sent to the laser ablation laboratory for Pb and Ag analysis. A separate portion of the sample was milled to ~ 100 microns and analysed by XRD.
