Final answer:
The Argyle mine in Australia is the only diamond mine in a lamproite pipe producing a significant quantity of diamonds, including rare pink and red ones, yet the local communities seldom benefit from the mining wealth.
Step-by-step explanation:
The Argyle mine in Australia is considered the only viable diamond mine in a lamproite pipe. The Argyle mine is noted for producing a large portion of the world's diamonds, including the highly prized pink and red diamonds. Despite the presence of diamond reserves and other minerals and ores, the economic benefits from the mining operations rarely benefit the individuals working within these mines, with the wealth generated often not reaching the local communities.
