QUALITY ASSURANCE / QUALITY CONTROL (QA/QC)
Niblack Mineral Development Inc. (the “Company”) maintains a rigorous quality control program with respect to the preparation, shipping, analysis and checking of all samples and data from the Niblack Properties. Quality control for drill programs at the Company’s projects covers the complete chain of custody of samples, including verification of drill hole locations (collar surveys and down-hole directional surveys), core handling procedures (logging, sampling, sample shipping) and assay-related work, including duplicate sampling, “check analyses” at other laboratories and the insertion of standard and blank materials. The QA/QC program also includes data verification procedures. Quality control was carried out by Niblack Mineral Development Inc. employees under the supervision of the Company's Vice President of Exploration, Peter Kleespies, M.Sc, P.Geol. Mr. Kleespies is a qualified person as described by National instrument 43-101.
Niblack Mineral Development Inc. has established a rigorous analytical quality control and quality assurance program with respect to sample analysis as part of its overall QA/QC protocols. This program includes the systematic insertion of blank materials (coarse and pulp) as well as certified reference materials (standards) into the sample stream. In addition, duplicate sampling (from core, reject and pulp materials) and “check” assaying (splits of coarse reject material sent to a second laboratory) are performed on a regular basis. Blank samples are used to check for possible contamination in laboratories. Field duplicate samples quantify over-all precision, while certified standards determine the analytical accuracy..
USA – Niblack Project (Polymetallic – Au, Ag, Cu, Zn)
Sample preparation and analysis is done at ISO 9001 accredited ALS Chemex laboratories in Vancouver, BC. All samples are assayed for gold by 30 g fire assay fusion with Inductively Coupled Plasma – Atomic Emission spectroscopy (ICP-AES) finish. Copper, silver, zinc, lead and 29 additional elements are determined for all samples by four acid digestion, followed by ICP-AES finish. All over limit copper, zinc or lead results (greater than 10%) and all over limit silver results (greater than 200 grams per tonne) are re-assayed by high grade single element four acid digestion ICP-AES analysis. As part of a comprehensive QA/QC program, one standard is inserted into the sample stream in each group of 20 samples, as well as one or more field blanks in each analytical batch. One sample in each group of 20 is a duplicate, which is analyzed by Acme Analytical Laboratories in Vancouver.
