Dear Katusa Research reader,“Don’t buy s**t.”You might find this statement offensive… but it might contain the three most valuable words in natural resource investment. When I look back at my 16-year career in natural resources, I think about how those three simple words – “Don’t buy s**t” – could have saved me millions of dollars… if I’d only listened to them when I was starting out.I guess I’m one of those people that has to learn the hard way.“Don’t buy s**t” is an investment rule that advises us to ONLY invest in super high-quality natural resource assets.I’m talking about projects of large size… in business-friendly countries… with straightforward geology… and excellent economics.Think oil fields in Texas… gold mines in Nevada’s spectacular Carlin Trend… and giant copper mines like Chile’s legendary Escondida mine.In other words, ONLY invest in assets that very smart, very capable resource company CEOs would buy for their own companies. I’m talking about billionaire legends like Ross Beaty and Lukas Lundin.I’m fortunate to call both these men friends and mentors. Both have done business all over the world… both have made themselves and shareholders billions of dollars… and both look at resource projects through a lens most individual investors never use.You see, small, risky resource stocks are often the focus of sensational and successful marketing campaigns with amateur investors. However, these stocks “blow up” shareholders with incredible regularity.Top resource business owners don’t waste their time with that stuff. They buy high-quality assets that can drive their companies forward and produce huge cash flows for years and years.When you spend time with resource entrepreneurs like Ross and Lukas, you quickly learn how important it is to buy size and quality… and not risky, low-quality “s**t” that ends up wasting valuable time and energy.I confess: When I started out in the resource game as young man, I invested in quite a few “amazing story” stocks. I invested in projects an experienced resource business operator would call “s**t.” These projects either weren’t big enough to interest major players, had poor economics, were located in risky jurisdictions with shaky political regimes, or all three.As a group, these kinds of stocks cost me far more money than they made me.If you’ve invested in natural resources for more than a few years, there’s a decent chance you’ve made some of the same mistakes I have. And now, you might be like me… you ONLY want to invest in “top tier,” world-class resource assets… the kind coveted by experienced mining and energy operators with very deep pockets.There is always a “bid” for world class assets. They are always in demand with knowledgeable resource executives.They are the kinds of assets that can make you truly rich – WITHOUT taking crazy risks.Approach your resource investments just like a great resource entrepreneur wouldI admit… I should have learned it sooner. It’s brilliant, simple, and effective. But it’s the cornerstone of my investment approach now… and it’s made me more money than I’ll ever care to spend.I hope this piece of advice can benefit you.I’m writing this letter not just to share that valuable advice with you, but to alert you to a truly incredible situation in the oil and gas market.Right now, there’s an opportunity to buy your share in one of the world’s richest, biggest oil and gas fields… at a huge discount to what others are paying for similar top tier assets.Again, I’m talking about owning a super high-quality collection of oil and gas assets… located in one of the world’s premier oil and gas districts. I believe it’s just short matter of time before a large oil company makes a deal to buy these assets (which are 100% owned by a small and brilliant oil operator).I don’t believe this opportunity will last for long. I estimate this world-class oil field is selling for an 80% discount to what others are buying for similar top tier assets.Soon, the world will wake up and realize what is going on and there will be rush to buy these assets. But if you act quickly, you can secure your spot at a bargain price… before the crowd arrives.I’m so confident this is a low-risk way to make massive capital gains that I’m willing to “bet” $3,500 on your success. It’s an incredible situation that you can learn all about right here.Regards,MarinP.S. Again… if you want to achieve success in resource stocks, you must BUY QUALITY. Learn how to do so right here.
