Infograms, Royalties and Technical Papers
YCS has developed some infograms (information sheets) about water contamination caused by mining. These are intended to familarize concerned citizens with what levels of contaminants in water that comes from mine sites that companies should be aiming for. They represent the Maximum Authorized Concentration in a Grab Sample that should be authorized. Sometimes mines refer to the Maximum Authorized Monthly Mean Concentration. This is typically half of what these infograms show. NOTE: These concentrations are not municipal water drinking standards...instead they are essentially end-of-pipe water standards for an operating mine, and they represent the very maximum. Most mines should be aiming for levels below what these infograms show.
The figures used in the infograms are from Column four of the Canadian Metal Mining Effluent Regulations (MMER): Maximum Authorized Concentration in a Grab Sample (Column Four is the highest number of the MMER regs)...except for Selenium which is from Canadian Council of Ministers of the Environment (CCME) Water Quality Guidelines for the protection of Aquatic Life.
Contaminants addressed include the most common environmental contaminants associated with Yukon mining operations:

YCS does an occassional op-ed piece in the Yukon News. These pieces have focussed on royalties. Here are some recent ones:
- Wed Jan 20, 2016 'Hard luck on those hard rock royalties'
- Wed Jun 10, 2015 'Mining Savings For A Rainy Day'
- Wed May 20, 2015 'The Wealth We Give Away'
- Fri Sep 9, 2011 'Raise The Royalty Rates'
Further to the newspaper articles, there are a couple of papers and submissions to government that migth be of interest to those concerned with the Yukon mining royalty regime:
- Yukon Mining Royalties - a YCS perspective (done in May 2008 but still valid).
- Raise The Royalty Rates - examines the low Yukon mineral royalty rates and tries to analyze the new Federal transfer agreement.
- Yukon Royalty Rates- looks at how low Yukon royalty rates are in light of a NRCan study.
- YCS Comments on Proposed Yukon Quartz Mining Act Royalty Regulations - this was done in June 23, 2009

Acid mine drainage (AMD) refers to the outflow of acidic water from a mining site. In most cases, this acid comes primarily from oxidation of iron sulfide (FeS2, also known as pyrite or "fool's gold"), which is often found in conjunction with valuable metals. Acid mine drainage is a major problem with many hardrock mines, including almost all mines where the metal ore is bound up with sulfur (metal sulfide mines).
