Technical Report

The 30-Second Summary

What is a Technical Report? A Plain English Definition

Imagine you're considering buying a large, undeveloped plot of land because you've heard rumors of buried treasure. You wouldn't just take the seller's word for it. You'd hire a team of independent experts—surveyors, geologists, and maybe even a treasure-hunting veteran—to give you a detailed, unbiased assessment. They would drill core samples, analyze the soil, estimate the probability of finding anything, and calculate the potential cost of digging it all up. A technical report is precisely that expert assessment, but for a publicly traded mining, oil, or gas company. In the world of investing, you can't just say, “We think there's a lot of gold in this hill.” Securities regulators in countries like Canada (with its NI 43-101 standard) and Australia (with the JORC Code) require companies to produce these standardized reports to protect investors from misleading claims. These documents are written by a “Qualified Person” or “Competent Person”—an accredited and independent geoscientist or engineer—who puts their professional reputation on the line with their findings. The report translates complex geology into the language of business by categorizing the underground assets into different levels of confidence: 1. Mineral Resources: This is the “what we think is there” category. It's an estimate of the valuable material in the ground, but its economic viability hasn't been fully proven. Resources are further broken down by confidence level:

2. Mineral Reserves: This is the holy grail for a value investor. A resource only becomes a reserve after a detailed study proves it can be economically and legally mined. This is the portion of the “measured” and “indicated” resources that is actually profitable to extract at a given commodity price. Reserves are also broken down:

Think of it like apples on a tree. Resources are all the apples you can see on the tree, including those on the highest, thinnest branches. Reserves are only the apples you can actually reach with your ladder, pick, and sell at the market for a profit after accounting for your time and effort. Many investors get burned by confusing the two.

“The business schools reward difficult, complex behavior more than simple behavior, but simple behavior is more effective.” - Warren Buffett. While not directly about technical reports, this quote reminds us to cut through the geological jargon and focus on the simple business question: Can this company profitably get this stuff out of the ground?

Why It Matters to a Value Investor

Value investors, by nature, are deeply skeptical of businesses they cannot understand and whose futures are wildly uncertain. Most mining and exploration companies fit this description perfectly. Their success depends on three highly unpredictable variables: the price of a commodity, the success of a complex engineering project, and the geology of a rock formation miles underground. This is a far cry from analyzing the durable competitive advantage of a company like Coca-Cola or See's Candies. So, why should a value investor even bother with a technical report? Because if you ever find yourself analyzing a company in the natural resources sector—perhaps it's trading for less than its cash on hand, or it's a spin-off from a larger company you own—the technical report is your only anchor to reality. It's the primary tool for assessing the “A” (Assets) in a balance sheet that is otherwise just cash and a dream. Here’s how it aligns with core value investing principles:

In short, the technical report is a tool for a value investor to impose discipline and realism on an industry that is rife with hype and uncertainty.

How to Apply It in Practice

You don't need a degree in geology to extract value from a technical report. You need the mindset of a skeptical banker who is being asked to fund the project. Your job is to poke holes in the story.

The Method

Here is a practical, step-by-step checklist for a non-expert to review a technical report:

  1. Step 1: Check the Author and the Date.
    • Who are the “Qualified Persons” who signed off on the report? A quick search can reveal if they are from a large, reputable engineering firm (like SNC-Lavalin, Hatch, or Ausenco) or a smaller, less-known consultancy. Independence and reputation are key. An old report is also a red flag; geology doesn't change, but economic assumptions (like costs and metal prices) become stale very quickly.
  2. Step 2: Jump Straight to the Reserves.
    • Ignore the exciting headlines about “billions of pounds of inferred copper.” Scan the document for the “Mineral Reserve Statement.” This is the number that matters. If the company has no reserves and only resources, it's not a business yet; it's a science project. For a value investor, the analysis often stops here.
  3. Step 3: Scrutinize the Economic Assumptions.
    • This is the most important step. The report will be based on a feasibility study that uses a set of assumptions to calculate the project's Net Present Value (NPV) and Internal Rate of Return (IRR). Look for these numbers:
      • Commodity Price: What price for gold, copper, or lithium are they using? Is it higher than the current spot price? A project that is only profitable at a price 30% above today's market is incredibly risky. Conservative assumptions are the mark of a credible report.
      • Operating Costs (OPEX): How much will it cost to mine and process each tonne of ore? Compare this to existing mines in the same region.
      • Capital Costs (CAPEX): How much will it cost to build the mine? Be wary of initial CAPEX estimates; they are notorious for ballooning.
      • Discount Rate: What rate did they use to calculate the NPV? A standard rate is 8%, but for risky jurisdictions or complex projects, a higher rate (10-12%) is more appropriate. A low 5% discount rate can make a mediocre project look fantastic.
  4. Step 4: Understand the Study Type.
    • Not all reports are created equal. They are based on different levels of engineering and economic studies:
      • PEA (Preliminary Economic Assessment): The lowest accuracy level (+/- 30-50%). It's a back-of-the-envelope calculation. Treat any valuation based on a PEA with extreme skepticism.
      • PFS (Pre-Feasibility Study): Better accuracy (+/- 20-30%). More detailed engineering work has been done. This is a significant step up.
      • FS (Feasibility Study / Bankable Feasibility Study): The highest accuracy level (+/- 10-15%). This is a detailed blueprint for the mine, and banks will often lend against a positive FS. For a value investor, a project isn't truly de-risked until it has a positive Feasibility Study.

Interpreting the Result

Your goal is not to find a “good” report, but to understand the risks embedded within it.

By applying this skeptical lens, you can use the technical report to build a massive margin_of_safety or, more likely, to quickly move the company into your “too hard” pile.

A Practical Example

Let's compare two fictional gold exploration companies to see these principles in action. Both have a market capitalization of $100 million.

You find their latest technical reports online. Here's a comparative summary:

Feature Gold Dream Inc. Steady Metals Corp.
Study Type Preliminary Economic Assessment (PEA) Bankable Feasibility Study (FS)
Asset Base 5 million ounces of Inferred Resources 2 million ounces of Proven & Probable Reserves
Gold Price Assumption $2,500 / oz $1,750 / oz
Current Gold Price $1,900 / oz $1,900 / oz
Projected NPV $500 million (at $2,500/oz gold) $250 million (at $1,750/oz gold)
Author Small, unknown consultancy Major, reputable global engineering firm
Jurisdiction Unstable, high-risk country Established mining district in Canada

Value Investor's Interpretation:

This example shows how the technical report, when properly interpreted, acts as a powerful filter to separate speculative hype from potential investment substance.
