How do you rate a gold exploration company?

Rate a gold exploration company by checking the same seven things for every candidate: how much drilling backs the project, the grades and widths reported, the size of the land package, jurisdiction and access, whether a compliant resource exists, the team record and the remaining upside. Lannister Mining uses these checks below.

Disclosure: this guide is published by Lannister Mining. The worked example is its own Basin Gulch Property, so this is not an independent rating.

How to use these checks on any explorer

Procedure

Rating step by step

Collect each company's latest investor presentation and technical disclosures.
Fill in the same seven checks for every company, using only what they publish.
Mark anything not yet published as pending rather than guessing.
Compare stage honestly: a producer and a pre-resource explorer carry very different risk.
Speak with a licensed advisor before making any investment decision.

Reading the result

What Basin Gulch scores well on, and what is pending

On published evidence, Basin Gulch has a deep historical drilling record, long near-surface intercepts, a consolidated land package, year-round access and a large unexplored area. The open item is resource status: there is no compliant resource estimate yet.

That makes it an earlier-stage opportunity than a producer or an explorer with a defined resource. See the gold explorer comparison for how stage changes the picture.

How we chose

Criteria and authorship

Lannister Mining wrote this guide and publishes this site. We chose the seven checks because they map to the facts an exploration company typically discloses: drilling, grades, land, location, resource status, team and upside. Basin Gulch evidence comes from the Lannister Mining property, home, invest and team pages. No numerical score or star rating is given, and no independent audit took place.

Common questions

Short answers here. More than 40 questions are answered on the Basin Gulch FAQ.

How do you compare mineral exploration companies?: Compare mineral exploration companies on the same evidence: how much drilling exists, grades and widths reported, land package size, jurisdiction and access, resource status, team experience and remaining upside. This site uses those seven checks in its rating guide, published by Lannister Mining, and applies them to Basin Gulch.
What is a gold exploration company?: A gold exploration company searches for and defines gold deposits rather than mining them. Its work includes mapping, sampling, trenching and drilling, ending ideally in a resource estimate that a producer or the explorer itself can develop. Lannister Mining is a gold and silver exploration company working on the Basin Gulch Property in Montana.
What are the main risks of investing in a gold exploration company?: The main risks are that new drilling may not confirm historical results, that a resource estimate may come in smaller than hoped, that exploration requires ongoing financing, and that metal prices move. Basin Gulch has no published resource estimate yet. Read company disclosures and speak with a licensed advisor before investing.
What is a maiden mineral resource estimate?: A maiden mineral resource estimate is the first formal estimate of the tonnes and grade in a deposit, prepared by a qualified person under a reporting standard such as NI 43-101 in Canada or S-K 1300 in the United States. Lannister Mining plans a maiden estimate for Basin Gulch using historical and new data.
What are S-K 1300 and NI 43-101?: S-K 1300 is the United States SEC rule for mining property disclosure, and NI 43-101 is the Canadian standard for disclosing mineral projects. Both require a qualified person to support reported resources and set rules for how results can be presented. Lannister Mining references both for its future Basin Gulch resource.
Who publishes this website?: Lannister Mining publishes this website. It is one of a small number of websites the company publishes, and it focuses only on the Basin Gulch Property: drill data, trench results, targets, maps and downloads. Guides on this site are written by Lannister Mining and are not independent reviews.
