Arizona Silver Exploration vice president of exploration Greg Hahn joined Proactive's Steve Darling to share recently shared some exciting news that it has obtained highly encouraging results from re-assays using the metallic screen procedure on specific drill holes at its Philadelphia gold project in Arizona.
According to Hahn, the interval with the highest grade that underwent re-assaying showed a substantial increase of 42.2%. The gold grade rose from 51 grams per ton (Gpt) to 72.5 Gpt. As part of the spring 2023 drilling program, the company selected a total of 24 samples comprising both high and low-grade material for re-assaying. These samples were chosen based on the presence of visible gold.
Hahn further explained that the application of the Metallic Screen process resulted in an average grade increase of 25.9% across the selected sample suite. The re-assaying of low-grade samples using the metallic screen method demonstrated grade discrepancies generally below 0.5 gpt gold, with the majority falling below 0.1 gpt gold. This suggests that coarse gold is not a significant concern in the lower grade samples submitted for metallic screen analyses.
