Rex completed column leach test work on two bulk samples taken from the two most representative lithologies within the Bells Project, located next to drill holes HR19-001 and HR19-004 (Sites 1 and 4 respectively). The samples were collected using a small backhoe excavator. The column leach test work was completed at KCA (Kappes, Cassidy & Associates) Labs in Nevada, USA with samples crushed to <37.5mm and then agglomerated with 5kg/t of cement. Column leach test results confirm Bells is highly amenable to heap leaching. Gold recoveries of 85% and 86% from two bulk samples. Notably, recoveries (based on leach solution assays) were: over 60% at 5 days over 80% at 22 days. Important input and output physicals: Crush size was 37.5mm (1½ inches); No lime was added; Cyanide consumption was low; Overall 'slump' was very low at 1%; Cement was added at 5kg/tonne (agglomeration). These results are in line with historical column tests (80%-90% recovery) which correlates well with the actual recoveries ultimately achieved at the Hog Ranch operation circa 1988-1993. Samples tested are representative of the expected lithology at the Bells Project.
