Probably about as many as rolls of the dice that don't pay off. That doesn't make roulette a "capital contribution" to a valuable business enterprise.
You sir, must be inconceivably dense to both make that analogy. Mining leases are a capital investment to secure rights to both resource exploration and extraction. In order to make any money off them, choice of lease to purchase requires substantial forethought (otherwise,it is a roll of the dice) and the lease price (since they are resold on a secondary market) is a way to market price the risk and potential value of the resource rights, to allow property owners who don't have e capital to explore or extrat resources to benefit from leasing the land to those that do. Due to a relatively efficient market in resoure lease pricing, ultra-high payoff leases are exceedingly rare, as high probability one's are priced higher accordingly. Additionally, leases in government owned land provide a tax revenue stream that is not only valuable, but well indexed to root economic growth---success in mineral recovery translates to a greater economic benefit for both the private and public sector, while allowing government held land to be utilized efficiently, without the government itself having to be in the exploration and extraction business, and allow efficient selection of the most cost effective private firm (comparable to spectrum auctions, where the company that sees the most potential profit in a segment will also likely be able to bid the most, allowing market maximization of a societally shared resource).
Normally I don't demean myself, or waste my time, responding factually to your typical poorly researched, talking point based, quasi-Marxist drivel, but this was the last straw. Either post information of value, or don't post at all.
