Hi netnet,
I have been trying to follow the metals sector (mainly precious metals) for the past year or so. I attended the Hard Assets Investments conference in SFO last November and wished that I had attended earlier too. As I think you are in the Bay Area, you can attend it for free this November.
As far as royalty companies go, I follow a company called Sandstorm Resources (SSL.V) fairly closely. It's a pretty new company with a model similar to Silver Wheaton. In fact, the CEO and CFO were among the first 5 employees or so at Silver Wheaton. I have not taken a position yet as I am not very sure about their incentives..they keep issuing options as well as regularly raise money. In fact, they just announced a big offering this week. But I do think they have made some pretty smart investments last year in 4 companies (Luna, Santa Fe Gold and Silvercrest have all started production recently). Disclosure: I have a pretty big position in Santa Fe Gold (SFEG.ob) as I think they are pretty conservative and flying under the radar currently. They are supposedly a very low cost producer of gold/silver.
Another unique royalty company I came to know recently is Solitario Exploration & Royalty Corp. (XPL). You can listen to their latest presentation at the Denver Gold show last month. I think they are about 2-3 years away from receiving any meaningful cashflow from their investments. Disclosure: No position.
One other tiny company is Bullion Monarch Mining (BULM.ob). Even though they seem to have pretty good assets, I don't have much confidence in their management. But they do get around 5-6 M a year from Newmont Mining and are involved in a lawsuit against them for additional royalties. They seem to take this cash flow and invest it in a speculative oil shale technology play. Disclosure: No position.
A couple of other interesting plays out there are: Golden Predator Corp (GPD.TO) and Endeavour Mining Corp (EDV.TO). GPD is an interesting royalty and a core precious metal exploration play (mainly in Yukon). They have a huge land package in Yukon and are very early in their exploration cycle. They do get about 1M from royalties now and are expected to get a lot more in about 4-5 years timeframe. EDV has recently made some smart acquistions and sold one of them for a huge gain (about 80M in about 6-7 months timeframe). They recently changed their name (from Endeavour Financial) to highlight their new focus on being a gold company. Disclosure: No position.
If you are really interested in solid management and asset plays, I will recommend you to follow billionaire Rob McEwen. I feel that he is one of the smartest and most ethical guys out there in the resource sector. He was the former CEO of Goldcorp and a huge investor in his two companies US Gold (UXG) and Minera Andes (MNEAF.OB). Minera just about doubled in the last month. I really feel that he could be referred to as the Warren Buffett of the mining sector. I wish I had taken a position in these two companies early this year, but did not as I wanted to look at production plays or close to production plays. Also, Minera was involved in a huge dispute with their partner Hochschild till recently which got resolved finally. Goldcorp's recent announcement related to the takeover of Andean resources for about 3.5 billion is also a big reason for their stock rise.
One of the other great success stories I have followed is GORO. The Reid's are pretty unique in whatever they do and built a 1 billion dollar company without caring about Wall Street till recently. I believe their history is solid and are connected to Rob McEwen also. I really wish that I knew about them much earlier. I was very close to taking a position at around 10$ this year, but shied away.
One other solid undervalued company (in my opinion) that I came to know recently is Andean American Gold (AAG.V). They have a solid asset in Peru which is expected to go into production in about a year's time. Their Invicta asset is a huge one in terms of the mind boggling economics. I have not yet taken a position, but regret every day for the past month or so for not getting in. It has been hitting highs on almost a weekly basis. It's just getting to be noticed and I think that it's going to be a huge multibagger like GORO was back in 2006.
