Cam’s 100% correct with everything he said, that is how legitimate mineral deals occur from start to finish. Anything further than 30-days for due diligence is completely excessive and the company is likely taking you for a ride. The only time I’ve seen it take longer than 30 days was when there were intense curative measures necessary, but the original PSA was 30-days and they simply extended it once they realized the title needed a lot of work. So, never sign a PSA longer than 30 days unless there is an actual reason to do so, otherwise you are tying up your minerals from being marketed for 4 months! What if they back out of the deal after 100 days? That’s time wasted for you and your ability to effectively market the asset(s).
