Gold exploration

What a gold exploration company does, and where Lannister Mining fits

Last updated: November 2026. Published by Lannister Mining.

A gold exploration company finds and defines gold deposits before a mine is built, and Lannister Mining does this at Basin Gulch.

Lannister Mining is a mineral exploration company focused on gold and silver at the Basin Gulch Property in west-central Montana. Its exploration for gold builds on more than 320 historical drill holes and aims to confirm and expand near-surface oxide mineralization toward a Maiden Mineral Resource Estimate.

What do mineral exploration companies actually do?

Mineral exploration companies search for, test and define deposits of metals such as gold and silver. Their work runs from mapping and sampling to trenching and drilling, then to a mineral resource estimate reported under standards such as NI 43-101 in Canada or S-K 1300 in the United States.

How to compare gold exploration companies

Criteria that apply to any explorer

When looking at gold exploration companies or silver mining companies at the exploration stage, compare each on the same points: jurisdiction, how much data already exists, how much ground is untested, access and infrastructure, project stage, and the track record of the team.

This site does not rank companies. It presents Basin Gulch against these criteria so readers can apply the same test to any other project they are considering.

Basin Gulch against those criteria

Jurisdiction: Philipsburg Mining District, Montana
Existing data: more than 320 historical drill holes
Untested ground: about two-thirds of the property
Access: year-round from Philipsburg, about one hour from Butte
Stage: exploration, with a Maiden Mineral Resource Estimate planned
Team: history at K92 Mining, Fosterville South Exploration, Arena Minerals and Thesis Gold

Precious metals market context

Silver production in the northern Rockies

Hecla reported second quarter 2026 revenue of $334 million and free cash flow of $136 million, with its Lucky Friday mine in Idaho setting a quarterly silver production record of 1.5 million ounces, according to a roundup published on Rohstoff-Welt. These are Hecla figures, not Lannister Mining figures.

Common questions

See all questions

What does a gold exploration company do?: A gold exploration company finds and defines gold deposits before any mine is built. Typical work includes mapping, sampling, trenching and drilling, then estimating a mineral resource to industry reporting standards. Lannister Mining is doing this at Basin Gulch, building on more than 320 historical drill holes.
Is Lannister Mining a gold exploration company?: Yes. Lannister Mining is a mineral exploration company focused on gold and silver at the Basin Gulch Property in west-central Montana. Its work centres on near-surface gold and silver oxide mineralization and on advancing the property toward a Maiden Mineral Resource Estimate.
Is Lannister Mining a silver mining company?: Lannister Mining explores for silver as well as gold, but it is an exploration company rather than a producing silver miner. Historical trench results at Basin Gulch include silver grades from 23 to 54 g/t alongside gold, and the property sits in a district known for Montana silver history.
How do you compare mineral exploration companies?: Compare mineral exploration companies on the same points: jurisdiction, size and quality of existing data, how much ground remains untested, access and infrastructure, project stage and team track record. The methodology page explains how this site presents Basin Gulch against those criteria using only reported facts.
Is Lannister Mining one of the top gold exploration companies?: This site does not rank gold exploration companies. It is published by Lannister Mining and presents facts about the Basin Gulch Property so readers can make their own judgment. Those facts include more than 320 historical drill holes, a 1,107-hectare land package and highlight intersections such as 1.8 g/t gold over 162 metres from surface.
What is the difference between an exploration company and a mining company?: An exploration company searches for and defines mineral deposits, while a mining company extracts and processes ore from a built mine. Exploration companies such as Lannister Mining create value by advancing a property through drilling and resource estimation, which can lead to partnerships, development or sale.
