MTR are down today, but for reasons completely unrelated to the scoping study. It is also worth noting that they were 15% down before the scoping study came out, and now more or less flat despite the goings-on.
With the ASX being a resource-oriented exchange, I doubt many would look to MTR's listing on AIM when reviewing a scoping study - NPV might be a better place to start.
