...and if you look on page 11 of the document you just referenced you'll see that just the NYSE alone has 3x the amount of mining company market value than the TSX does. The TSX is where a lot of the smaller companies are (yes there are some big ones too), but generally the US is where the big boys play.
Also, this document was from 2013. Couldn't tell you what the most recent data is. A lot of those companies listed on the TSX and TSXV probably aren't even around anymore with how bad the mining recession has been the past 7 years or so... which is finally now turning around.
Also, I'm not saying that the TSX is not a good home for mining companies. I'm just saying that being on a major US exchange and simplifying things to 1 exchange and 1 currency where all the volume is recorded would make it much better for the average investor to find and figure out this company - especially for US investors.
