RE:Time frame Historical timeframe.
The ramp was developed to 129 level by Sept 30th. See slide 12 here;

Further, because mining at Kiena takes place in an upward direction after each interval down, mining then occurred in the following sequence 129->128->127->126->125. So presumably ore from level 129 started getting minied shortly after Sept 30th.
