QAQC
The Moss Gold-Silver Project
Northern Vertex Inc. (NEE) QA/QC procedures at the Moss Property are designed to ensure investor confidence and to comply with NI 43-101 Standards of Disclosure for Mineral Projects. The sequence of steps, from drilling to announcement of results, is the following:
A drill plan is designed using GIS software and hole locations are "spotted" in the field using GPS measurements under the supervision of the site geologist; drill pads appropriate to the location are prepared. Clear instructions relating to hole location, azimuth and inclination are provided to the drill crew by the site geologist..
RC drilling provides a continuous sample stream which passes through a cyclone and into a rotating sample splitter: half the sample is captured into a cloth bag inserted into a 5 gal pail; the remaining half -- the reject sample -- is collected in a bucket and transferred to a bag for storage. A second sample for comparative analysis is taken from the reject sample. Samples are separated into 5 foot (1.5 m) intervals..
When the hole is finished, a down-hole survey is performed to determine the deviation of the hole from its intended course..
Split samples are drained of liquid and a washed representative from each 5 foot sample length is placed into a tray for lithological description and reference..
The samples trays are logged on site, a paper log prepared which is then input into an electronic format..
The sample bags are securely fastened and transported to a gated area on the property for storage. Every few days samples are shipped by bonded freight or picked up by the lab's truck. .
The diamond drill produces HQ size core (6.35 cm diameter); core is placed in reinforced, cardboard boxes designed specifically for core transport and storage; each box has a 10 foot (3.0 m) capacity; it is the drillers' responsibility to insure that core is in the correct order and that length tags (small wooden blocks) for each rod-length of core are inserted..
Core lithology is logged in the Company's core facility by the site geologist; measurements of core between rod-length tags are taken to determine drill core recovery and the proportions of core fragments greater than 10 cm in length are measured to determined RQD values and entered into the log. Core logs are created directly in an electronic log template or written core logs are subsequently converted into an electronic format..
Diamond saw blade cutters are used to cut the core by Company personnel. Half the core is retained at the Company's core facility for future reference..
Strong plastic rock sample bags are labelled with sample numbers on the outside and sample tags inserted inside. Samples are then transported by bonded freight or the lab's truck for assay. A chain of custody document accompanies every shipment. For each RC and core drill hole, one of four certified chemical standards supplied by CDN Resource Laboratories Ltd (Vancouver) is inserted every 10th to 20th sample for precision and accuracy control. In addition, a second sample of RC chips or ΒΌ core duplicates and certified sample blanks are inserted at a rate of 2.5% to 5% of samples..
The Company uses certified analytical laboratories which also follow their own QC/QA procedures relating to the analysis of the samples. Standards that do not fall within three standard deviations of their established value trigger the re-analysis of the related sample batch. .
Results are tabulated by the laboratories and sent electronically to designated persons at Northern Vertex for verification and compilation. Results are reviewed by a qualified person for analytical veracity; they are then compiled into a NEE database in preparation for plotting as strip logs and on geological cross sections, analysis and interpretation..
Results are kept in strict confidence until a news release is prepared and the information released simultaneously
