Cross Gold Mine <br />December 2024 G2-3 <br /> <br /> <br /> <br />• Chain-of-custody documents shall be filled out and remain with the samples until custody is <br />relinquished. CoC document copies will be maintained at the Cross Gold Mine. <br />• Sampling equipment shall be decontaminated: <br />1. Wash equipment thoroughly with Luminox® detergent and hot tap water using <br />a brush or scrub pad to remove any particulate matter or surface film. <br />2. Rinse the equipment thoroughly with hot tap water. <br />3. Allow them to air dry for at least 24 hours. <br />4. Wrap equipment in one layer of aluminum foil. Roll edges of foil into a "tab" <br />to allow for easy removal. Seal the foil wrapped equipment in plastic and label. <br />• All ore/tailings samples must be thoroughly mixed to ensure that the sample is as representative <br />as possible of the sample media. <br />• Place the sample into appropriate, labeled containers. <br />• All samples requiring preservation must be preserved as soon as practically possible, ideally <br />immediately at the time of sample collection. Preservatives will be provided by the sampling lab <br />to ensure appropriate amounts. <br />• Ore/tailings samples will be collected by a small steel shove l, long armed dipper, or similar. <br />• During sample collection, if transferring the sample from a collection device, make sure that the <br />device does not contact the sample containers. <br />• At least once every 5 years, provide a duplicate sample of both tailings and ore to the lab for a <br />QA/QC check.
