It's hard to know how much difference it makes. Speaking from personal experience when I see an ad from a company I never heard of I do check them out.
An example on the right hand side of this page. The ad for Santo Mining . I did check them out . I didn't know they existed until I saw their ad . There are thousands of juniors so it's easy to get lost in the crowd.
Kelteras should have lots of connections so I hope he is working them for our advantage.
