Geology is difficult

A. Reader who will remain nameless sends in this pearl of wisdom to IKN Nerve Centre, rescued from the depths of the Rye Patch (RPM.v) Florida Canyon PEA dated June 2016 (to be exact, from page 88). Your humble scribe adds in the bold type:

"The lithology in the Florida Canyon deposit consists of a complex deltaic sequence of the Grass Valley Formation. The rocks are a complex and gradational sequence of silty and sandy rocks within dominantly argillites. The original lithology probably controlled the plasticity of the rocks and determined the degree of fracturing, which is the dominant ore control. Grade, however, is the more reliable and quantifiable method of defining the ore zones.”

Who knew?
