Lobo Tiggre: Junior Mining Speculation

Episode Summary

Executive Summary: Lobo of Independent Speculator explains how he learned mining investing from scratch, why rigorous field-based due diligence matters, and how conservative underwriting protects investors from “crap” assets and management hype. He covers feasibility study traps, commodity cycle thinking, portfolio construction across juniors and majors, and how to communicate technical ideas simply for generalist investors.

Main Topics: Career origin and learning curve: Lobo describes moving from nonprofit/libertarian fundraising into mining research through Doug Casey, emphasizing humility, intense learning, and mentorship from experienced investors and operators. What real due diligence means in mining: He argues due diligence is not reading a deck but testing the story: visiting projects, talking to locals and management, checking incentives, and assuming BS until proven otherwise. Feasibility studies, assumptions, and red flags: He explains how to assess studies by scrutinizing metal price assumptions, engineering firm credibility, political risk, payback period, and whether the project depends on unrealistic shortcuts. Commodity cycles and conservative underwriting: Lobo argues commodities move together in cycles, costs rise across the board, and marginal projects remain marginal even at higher prices; therefore, conservative assumptions preserve margin of safety. Portfolio construction and speculation sizing: He discusses how macro views guide sector exposure, why truly great specs are rare, and how portfolio weightings should evolve with opportunity rather than rigid allocation rules. Valuation mistakes by generalists: He warns that spreadsheet-driven models miss qualitative factors such as bad management, political risk, and scam-like behavior, especially in volatile junior mining names. Writing clearly about complex mining topics: He explains how feedback forced him to simplify his writing, using short sentences and plain language to make technical mining research understandable to generalists.

Key Arguments: Mining due diligence must be field-tested, skeptical, and hands-on; reading websites and decks is insufficient. Management quality and project credibility often cannot be captured in a spreadsheet, so investors need interviews, site visits, and local conversations. Conservative metal price assumptions are not just prudence—they reflect real-world cost inflation, cyclicality, and the fact that poor deposits remain poor. A short payback period is crucial, especially for large, capital-intensive base metal projects. Portfolio composition should follow opportunity quality and macro conditions rather than fixed sector percentages. Great mining specs are rare but can produce 10x-100x outcomes; the space offers periodic extreme upside if investors can tolerate volatility. Generalists often overtrust financial models and underweight qualitative red flags in junior miners. Clear writing in mining requires simplifying complex technical material without pretending the subject itself is simple.

Data Points: Time to becoming an expert: ~4 years - Lobo says he went from knowing nothing to being able to give Doug Casey stock recommendations within about four years. Career length: Almost 20 years - He says he has been doing the work for nearly two decades. Conservative gold price assumption example: $1,300/oz - He cites Barrick under Mark Bristow as using a gold price ceiling around this level. Example feasibility study gold assumption: $1,900/oz - He discusses a feasibility study using this gold price and argues that assumptions above spot can be dangerous. Copper bull case example: $7-$10/lb - Used as an example of how investors may anchor to future bullish copper prices when evaluating projects. Oil cost environment example: $150/oil - He argues a $7-$10 copper environment would likely coincide with much higher broad input costs. Short payback preference: <2 years ideal; >3 years difficult - He states this as a key underwriting rule of thumb for mining investments. Volatility frequency in mining: 10-baggers and 20-baggers every year; 40-50 baggers periodically - He emphasizes the rarity of knowing which stocks will do it, but says outsized winners are common in the sector. Historical 100-baggers: 2 examples known to Doug Casey - He cites two 100-bagger cases associated with Doug Casey’s investing history. One example of a 100-bagger: Brix from about $1 to $125+ - He recounts Doug Casey’s large gain before the scam unraveled. Tech Cominco crash example: ~$50+ to ~$3 - He cites the 2008 crash as a “stupid cheap” opportunity in a major company. Writing readability target: 7th-8th grade level - He says Porter Stansberry pushed the team to lower readability and simplify communication. Newsletter cadence: 1 email per week - He says Independent Speculator sends one email weekly and avoids spam.

Pivotal Quotes: "I realized that they were interesting people... and there wasn't really anything any of them had done that I didn't think I could do." — Lobo: Explaining the epiphany that pushed him from fundraising into learning investing and money management. "I assume bullshit and give them the opportunity to prove otherwise." — Lobo: His core philosophy on mining due diligence and management interviews. "Crap is crap." — Lobo: His blunt summary of why marginal deposits remain unattractive even in a higher commodity price environment.

Implications: For investors, the episode argues that mining success comes from skepticism, fieldwork, conservative assumptions, and flexibility—not spreadsheet certainty. For the industry, it highlights the premium on trustworthy management and realistic project design.
