and I don't mean to sound trite but the genuine answer is making money.
I focus on resource companies. Fundamental analysis driven approach with business experience, investment experience and some geology training but I am not a fully fledged geologist.
I do an enormous amount of research around the companies I get interested in. (I'm happy to share what I find but of course everyone should be doing their own due diligence. )
I recently met up with MYL company representatives, I was very impressed. They know their business and their plan of execution is well articulated. If you read their reports you will be able to guess what is coming next. It's well forecast for us all. If you have trouble reading it I'd suggest focusing on the next 4 months of drilling and results as they bring modern techniques to bear.
But on top of anything else I like to invest in stunning geological resources because I believe they always get mined. There is a reason the saying 'grade is king' exists
MYL have just such a deposit IMO. It will grow for years to come.
