Leapfrog's post, 29 Jan 18 (great summary - worth repeating):

Goal: Immediate Drilling to identify near-surface oxide minerals (particularly copper) that are commonly associated with underlying sulfide bearing porphyry systems 

Purpose: to determine the feasibility of an open pit copper heap leach, solvent extraction and electro winning operation and/or in-situ extraction process OR possibly high grade massive copper sulfide mine shipped directly to smelter, without or even with slight further treatment. 

Reason: timetable to mining operation is much shorter and at a substantially lower cost OR possibly shallow underground mine exploiting copper sulfide. Also at a much lower cost.
