Quality ControlDrill core samples were taken from sawn half core for every 1.5m or limited by apparent wall rock and mineralization contact. Half of the core was sent to the laboratory for analysis and the other half retained for archive. The channel samples are collected along sample lines perpendicular to the mineralized vein structure in exploration tunnels. Sample length ranges from 0.2 m to more than 1.0 m, depending on the width of the mineralized vein and the mineralization type. Spacing between sampling lines is typically 5 m along strike. Both the mineralized vein and the altered wall rocks are cut with continuous chisel chipping. The samples are individually secured in cotton sample bags and then collectively secured in rice bags for shipment to the on-site laboratory. For analysis, the sample is dried and crushed to minus 1 mm and then split to a 200-300 g subsample which is further pulverized to minus 200 mesh. A duplicate sample of minus 1 mm is made and kept at the laboratory archives. Two subsamples are prepared from the pulverized sample. One is digested with two-acids for analysis of silver, lead, zinc and copper with AAS. The other is retained as pulp reject at the lab for future reference. A routine quality assurance/quality control (QA/QC) procedure is adopted to monitor the analytical quality at the lab. Certified reference materials (CRMs), pulp duplicates and blanks are inserted into each lab batch of samples. QA/QC data at the lab are attached to the assay certificates for each batch of samples. The Company maintains its own comprehensive QA/QC program to ensure best practices in sample preparation and analysis of the exploration samples. Project geologists regularly insert CRM, field duplicates and blanks to each batch of core samples to monitor the sample preparation and analysis procedures at the labs. The analytical quality of the labs is further evaluated with external checks by sending about 3-5% of the pulp samples to higher level labs to check for lab bias.
Data from both the Company's and the lab's QA/QC programs are reviewed on a timely basis by project geologists.Guoliang Ma, P. Geo, Silvercorp's Manager of Exploration and Resource, reviewed the exploration data and prepared the scientific and technical information regarding exploration results contained herein. He is the Qualified Person on the project as defined under National Instrument 43-101 and has verified and approved the contents of this news release.
