one sample, we looked at a couple of samples, and they all were very consistent. we had a concentration or explosive concentration of 5.4%. the cutoff point is 5%. we know we ve had trouble in this area before. it was the same area where rescuers were pulled out the night that this occurred. again, we re not saying that this is this is a setback. it s not something that they won t get back in. we re going to continue to monitor that bore hole number 1. in addition, bore hole number 2 only 70 feet from cutting through into the mine is going to be cut through, and what that will do for us, it will double the quantity of air to ventilate this area. we have about 850 cfm of air coming out of bore hole 1. after we get bore hole 2 through, get a high-pressure fan set on it, we re also going to be pulling 850 through it.
