If that means 1,400oz from one week's worth of production (eg mining and processing) then that is a significant change and good news. I would just be cautious that it doesn't mean 1,400oz was poured last week, but it relates to a greater period of mining and processing (eg a months worth or so). Would be worth clarifying.
If your interpretation is correct, then why has MK not made this publically available to the market? This, IMO. would be very market sensitive information.
