Ann: Visible gold in Stacpoole North - Morning Star Gold Mine, page-61

Flat lying ore bodies can generally be defined as those having an angle of repose of less than 35 degrees or so. Broken rock in a stope will not rill (flow) naturally unless the floor of the stope is greater than circa 32 degrees - less than this requires mechanical measures to move it to the draw point. The cross section of Stacpooles indicates a flat lying structure although we haven't been given a North/South section for the full picture.

Mining flat makes still requires a 2 metre height for the airleggers resulting in massive dilution if the reef is in the 30-50cm thickness range.

AGAIN we are not given true widths of the intercepts.
