As one of leaders of how mining rhyolite rock impacts the environment industry, SBM always seeks innovation & excellence.
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks ...

Rhyolite is an extrusive igneous rock with a very high silica content. It is usually pink or gray in color with grains so small that they are difficult to observe without a hand lens. Rhyolite is made up of quartz, plagioclase, and sanidine, with minor amounts of hornblende and biotite. Trapped gases often produce vugs in the rock.

If this sounds like an argument to stop mining altogether - think how different our world would be with no iron, steel, copper etc. I think that there are many more things that also have an equal environmental impact on our planet. Lets think about air-travel and tourism. Think of car pollution. Think of deforestation. Think of greenhouse gasses.
