Editing Mining (section)

===Corporate classifications===
Mining companies can be classified based on their size and financial capabilities:
* ''Major'' companies are considered to have an adjusted annual mining-related revenue of more than US$500 million, with the financial capability to develop a major mine on its own.
* ''Intermediate'' companies have at least $50 million in annual revenue but less than $500 million.
* ''Junior'' companies rely on [[equity (economics)|equity]] financing as their principal means of funding exploration. Juniors are mainly pure exploration companies, but may also produce minimally, and do not have a revenue exceeding US$50&nbsp;million.<ref name=MEG-CorpClass>{{cite web|url=http://www.metalseconomics.com/pdf/PDAC%202009%20World%20Exploration%20Trends.pdf|title=Metals Economics Group World Exploration Trends Report|access-date=2009-05-05|publisher=Metals Economics Group Inc.|archive-date=2012-08-03|archive-url=https://web.archive.org/web/20120803095004/http://www.metalseconomics.com/pdf/PDAC|url-status=dead}}</ref>
