Thank you very much for the question. I will try to answer it in French.
Currently, we have a contract with two different companies for the three helicopters. We are in the process of developing a plan not to buy, but to lease. The next step is to lease the helicopters. We're trying to lease four. Ultimately, we don't have enough money to buy the helicopters, because they're very expensive. Right now, it's better for us to lease the helicopters with the equipment.
