Ann: High grade results and resource estimation from Menzies, page-6

High grading is definitly the way to go if you can find it. A good idea to try and prove plus 5g ore if it's the only way to keep BML interested and on the site...having decided to go with them for Selkirk it makes sense to keep the momemtum going and mine the other high grade deposits.

You dont want to be sitting around eating up your profits (from Selkirk) with overheads, while waiting for the next mine to be ready.
