Dave said last year (I can't remember when, could be on separate occasions) that once the mine is up and running drilling will be able to occur year-round - it's only a lack of infrastructure (accommodation, power etc) to deal with the harsh winters that prevents them drilling continuously. Therefore the mine will be continuous. And on your other question yes, I think you're right that shipments of ore will cease during some months each year. He said that there will be stockpiling of product even though production will be continuous (save for the occasional maintenance stoppages) once the mine's up and running.
