I don't think a successful flow test will have much effect on the share price. Technically it may be a success but financially so what. It's a bit like an exploration company finding a high grade of gold in a drill sample. It might cause a short stir but until the company can demonstrate it's going to make money it's just burning cash. To me the triggers that will improve the share price are an increased concern in society for reducing global warming and/or moves by the Company to build a power plant (I know it has to have a successful flow test first). One of the problems for all the hot rocks companies is that it's all taking too long and the initial fervour for green energy that brought investors in in the first place has long gone. Unfortunately the process can't be speeded up and the delay is reflected in the share price (which isn't helped by the current bear market). I still think PTR is the best of the bunch and look forward to the first electricity generation in the not too distant future.
