I usually watch the trading before making an entry, if it's being churned for accumulation they will happily sell you a few to keep the price down but also don't want to give up a lot so they pull the order on the sell side to make you pay a premium and then churn it back down.
I just play their game yesterday they pulled approximately 100k at 23cents from memory when they realized I was after a decent chunk likewise this morning at 24 cents. About a dozen trades so far, probably do 20 to get my fill.
Yes I'm also long term however I will generally buy 20-30% more than I want long term and trim them to take some profit along the way if the price increases of course.
Yes I agree RXM seems good value at current SP and looks likely, there is plenty of money looking for a good copper option on the ASX I have some exposure through BHP and an ETF but this is the only direct copper stock that I have liked enough to take a position.
Anyway we'll see how it goes. Good Luck.
