In an ideal communist society, the discovery of gold would first be very widely publicized. (A direct opposite of the likely case in a capitalistic society.) The subject of gold, its value, its importance to our society at this time, the needs for hard currency revenue of our society, and the displacement that would be caused by its removal, both environmental, and social. Everyone would be given as much information as could be reasonably assimilated, and the population at large would take some time to decide the needs of the many.
When that was done, a consensus would emerge. To mine, or not to mine. Since some would be more strongly hurt by the mining, the benefits to them would need to be made stronger as well. When the proper balance was achieved to gain the concurrence of a strong majority of the affected population, an agreement of the people, a law, would be enacted. It is inevitable that a small percentage would not agree however generous the compensation for their losses might be. Eminent Domain can exist in a communist society, but the process in a society dedicated to the principles of the society’s duty to the needs of the people will consider the range of those needs far more than that of a capitalist society.
I would willingly point out that by this time, a Capitalist society would have already allowed ten or so wealthy men to purchase the mineral rights to most of the land, with a minimum public fanfare, and the resulting low prices, borrowed the money, and begun mining gold. Some would consider this to be an advantage. Most of the people who sold out their rights unknowingly, and the people downstream of the mines would disagree. In an ideal communist society, it is quite possible that trillions in extractable gold lying under a lightly populated area might be considered not worth the cost of mining. In that case, the survey information would be archived, and a periodic reassessment of the needs of society would be carried out, to assure that the needs of the society as a whole were served by its use of resources.
Once the decision is made, the free communist approach is to allocate funds from central authority for additional compensation to the portion of the populace that has the skills and materials to bring to bear on the problem at hand. Once mining has begun, the deficit incurred from the central authority is repaid first and the compensation to the most strongly affected next. Additional funds are then allocated from the proceeds to provide training to replace the skills now in short supply for the rest of society, and the balance of the revenue is added to the general funds which provide benefits to our society. If the richness of the entire society was greatly improved, many other projects, perhaps considered to expensive before this, could be planned.
Specifics in matters of environmental impact, unique habitats involved, historic importance of the region, and other such matters would be part of the initial informational effort, not things brought up after the fact. The cost to the whole society is the balance to the benefit of the increase in wealth, of the whole society. In a capitalist society, the possibility of the very few being able to benefit at a great cost of the many is not important at all. Bottom lines in a capitalist system always have dollar signs on them. In this case, if the gold, or the coal lies under the most beautiful parkland in the nation, it might not be worth a trillion dollars to the people to give up the park.
Totalitarian communist societies would not follow this model, of course. The great flaw in communism, in my opinion, is not in the system itself, but in the fact that is cannot arise without imposition by either a small number, voluntarily, upon themselves, or by an act of despotism, upon a larger number. That makes it an unworkable system for nations, or even city states.
