Jun 11, ) screen. A split of 1,000 grams ("g") was taken and pulverized to better than 85%, passing a 75micron (Tyler 200 mesh) screen, and a 50 g split was analyzed by fire assay with an AA finish. Selected samples were reanalyzed using a 1kg cyanide leach (Bottle Roll) using "LeachWELL" or a 1kilogram ("kg") screen fire assay method.

Oct 15, 2021The Bottle Roll Leach Test work procedure comprised the following. 1. One 500 gram split of as received material was placed into a bottle and slurried with additional tap water to a total of 750 milliliters of added water. 2. The slurry was mixed thoroughly, and the pH of the slurry checked.
