To provide a benchmark against other zinc deposits, given that zinc generates approximately 45% of revenue from Fossey, a zinc equivalent2 grade of 12% has been estimated for the resource based on the geological boundary, increasing to 22% Zn at the higher, 5% (Pb+Zn) grade cut-off boundary – supporting the company’s view of the high grade nature of these deposits.

Nun fehlt aber noch das *cut-off*. Ich vermute, dass es die *als Abbruchkriterium gewählte Konzentrationsgrenze* sein könnte, kenne aber auch keinen geläufigen Begriff der Geostatistik dafür.
