Mining landfills better than digging new mines?

Sometime ago I read or heard about landfills being mined for gold in Japan

Looking into landfill mining, I found a large number of sites, mostly positive.  One I found a few weeks ago is Landfill Miners.

A search for “mining gold from landfill” or “mining copper from landfill” turned up a variety of sites about landfill mining, mostly positive.  It seems more recent articles are more positive than older articles.  Many projects reclaim a large variety of materials, many of which can be sold for less than mining the original materials.  Aluminum and copper are major materials in this category.
