4.5m ounces currently, so 10m ounces is a pipe dream until it happens. I do expect the cut-off grade to improve. People might be using the 10m oz figure from other deposits in West Africa, from GRY's presentation:
"Host to huge +10million oz deposits such as Obusai, Tarkwa, Syama, Ahafo, Sadiola, Loulo, Morilla, Tasiast."
