2005 & 2006 Program
In 2005 underground chip samples were taken from the drift to correspond with each round of approximately 4.8 m in length. Muck samples were also taken.
Each drill hole was sampled in two metre lengths or less as marked by the geologist. Sampling was based on visible mineralization. The samples were sawn in half, bagged, and put into plastic pails or fibre bags for shipping. A blank sample and a standard was included in each batch of 20 samples. In addition, one sample in every 20 is ¼ split to provide a duplicate.
The assay results are loaded directly from the laboratory into the Access database. The drill logs are entered into excel spreadsheets from the hand written logs.
Scott Wilson RPA visited the Eco-Tech Laboratory in 2005 to review the assaying methodology. Internal checks consist of a minimum two repeats, one blank, two resplits, and two or three reference standards, one for Cu, one for Ag or combined Cu/Ag, and one for Au/Pd. If native Cu is reported on the sample sheets, a metallic screen analysis is run in addition to the regular assay. Cu and Ag assays are determined using standard acid digestion followed by Atomic Absorption analysis. Au, Pd, and platinum are determined using standard fire assay methods followed by an Atomic Absorption analysis or ICP in the case of platinum. SWRPA were of the opinion that the sampling was being carried out to industry standards.
New Gold has a QA/QC program in place consisting of the addition of standards, duplicates, and blanks into the sample stream as described above. In addition a number of pulps were selected for reassay at an independent laboratory.
Scott Wilson RPA was of the opinion that the QA/QC program met or exceeded Industry Standards.
