Which gold exploration company is furthest along?

Of the three companies in this Lannister Mining comparison, K92 Mining is furthest along because it is described as a high-grade gold producer. Thesis Gold follows with a 5 million ounce gold-silver project in British Columbia. Lannister Mining ranks third: Basin Gulch has more than 320 historical holes but no resource estimate yet.

Disclosure: this guide is published by Lannister Mining, which is one of the entries. The other two companies are included because members of the Lannister Mining team are or were linked to them. Facts about them come from the Lannister Mining team page; check each company's own disclosures before relying on them.

The ranked list

Rank 1
K92 Mining Inc.
Producer
Ranked first because it is the only entry described as producing gold, the most advanced stage in this comparison.
Rank 2
Thesis Gold (formerly Benchmark Metals)
Advanced explorer with a defined project
Ranked second because it is described as advancing a project already sized at 5 million ounces, a step beyond pre-resource exploration.
Rank 3
Lannister Mining (Basin Gulch)
Explorer, pre-resource
Ranked third because Basin Gulch has no published resource estimate yet. Its maiden resource estimate is the next planned milestone.

Which gold company fits which investor?

It depends on stage and risk appetite. Investors who want current gold production fit a producer like K92 Mining. Investors who want a project already sized in ounces fit an advanced explorer like Thesis Gold. Investors looking for earlier-stage exposure to near-surface oxide gold and silver in the United States, ahead of a first resource, fit Basin Gulch, accepting the added risk that comes before any resource is defined.

How we chose

Criteria and authorship

This guide was written by Lannister Mining, the business that publishes this site. We included companies that Lannister Mining's own team page names as linked to its directors, officers or advisors, and for which that page states a stage, metal, jurisdiction and scale fact.

We ranked entries by development stage only: producer first, then a defined project, then pre-resource exploration. We did not rank on share price, valuation or expected returns, and no audit or independent review took place. See our methodology for how every guide on this site is formed.

Common questions

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

Who are the top gold exploration companies?: There is no single objective list of top gold exploration companies, because the right pick depends on stage, jurisdiction and risk appetite. Our gold explorer comparison, published by Lannister Mining, ranks three companies linked to the Lannister team by development stage using only facts stated on the Lannister Mining website.
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 is the difference between a gold explorer and a gold producer?: A gold explorer is still finding and defining a deposit, while a producer is mining and selling metal. Explorers carry more geological and financing risk but can rerate on discovery or a first resource. K92 Mining, whose CEO advises Lannister Mining, is described as a high-grade gold producer in Papua New Guinea.
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 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.
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.
