RE:Vein 4 (~1 km Long) You might refer to page 82 of the original PEA technical report on the Elder MIne Project for some relevent information. Development of different levels has been planned in this report and is to be carried out in phases over the course of the life of the mine. This was the original plan and one might assume that Abcourt has been operating according it. Levels closer to surface are to be developed later in the life of the mine.
Lower milled grades as you state would impact negatively upon ore transportation costs. That would likely be another cost consideration as to why the AISC are so high. Abcourt's dilution rates are also high.
Sounds like the search for higher grade mineralized ore will be a management priority. The newly found vein 9-1-5 is a good start in the right track. Management knows what they need to find. Try not to do too much of their work for them. They seem to be proceeding according to the original plan.
The share price of these penny juniors does fluctuate wildly at times. It's best to look at them as a longer term investment. One might choose to take advantage of lower price opportunities like this to make a more cost effective purchase. It is tax loss season.
Remember that only two months ago, Abcourt Mines still had almost $3 million in their bank account. Keep an eye on the cash levels going forward. But chances are that management wants to maintain it at current levels and/or let it grow slowly over time. Abcourt Mines is still a good speculation. And a good bank account instills a lot of confidence. But it is really a longer term play.
All the best! Java
