P2 Gold summarizes phase 3 met testing at Gabbs

PGLD · Price
Executive Summary
- P2 Gold reports substantially higher gold (98 % at 58 days), silver (90 %) and copper (85 %) recoveries from its Phase 3 metallurgical program on the Gabbs project after 115 days of leaching.
- The improved recoveries exceed those used in the May 2024 Preliminary Economic Assessment (PEA) and will be incorporated into an updated 2025 PEA, potentially enhancing project economics.
- The company retained Kappes Cassiday & Associates to conduct the program and plans to release final metallurgical results after completion of analysis.
Key Details
- Phase 3 Program Duration: 115 days of leaching (compared to interim 58‑day data).
- Gold Recovery: 98 % recovered by day 58; continued improvement through day 115.
- Silver Recovery: 90 % recovered by day 58; further increase observed up to day 115.
- Copper Recovery: 85 % recovered by day 58; ongoing increase through day 115.
- Comparison to May 2024 PEA Assumptions:
- Oxide gold recovery used in PEA: 78 % → actual now ~98 %.
- Oxide silver recovery used in PEA: 45 % → actual now ~90 %.
- Oxide copper recovery used in PEA: 54 % → actual now ~85 %.
- Impact on Economics (2025 Update): Updated recoveries will be reflected in a revised PEA slated for 2025; the May 2024 PEA projected an IRR of 56.5 % and NPV > US$1.6 billion at spot prices of $3,391/oz Au, $38.06/oz Ag, $4.35/lb Cu.
- Consultant: Kappes Cassiday & Associates (KCA) performed the metallurgical testing, focusing on cyanide addition during agglomeration and increased leach solution cyanide concentration to boost kinetics.
- Future Steps: Final metallurgical recoveries will be announced after completion of laboratory analysis; an updated PEA incorporating these results is planned for 2025.
Notable Quotes
“The phase 3 metallurgical program was established with a target of improving the leach kinetics and overall extraction by adding cyanide during agglomeration and by increasing the cyanide concentration in the leach solutions,” – Joe Ovsenek, President & CEO, P2 Gold.
“Recoveries and leach kinetics have significantly improved with 98 % of the gold, 90 % of the silver and 85 % of the copper recovered in the first 58 days of leaching.” – Joe Ovsenek.
