Here are plain answers to 46 common questions about mineral exploration, gold exploration, drilling, Montana, the Philipsburg Mining District and Basin Gulch.
Lannister Mining wrote these answers from its own published materials on Basin Gulch and from named public sources for industry figures. Jump to a topic below.
Mineral exploration is the search for concentrations of metals or minerals that could one day be mined economically. It moves from mapping and sampling to drilling, then to resource estimates and engineering studies. Lannister Mining is doing this work at the Basin Gulch gold-silver property in west-central Montana, where more than 320 historical drill holes give the company a starting dataset.
Gold exploration is mineral exploration aimed at finding and defining gold deposits, often with silver or other metals alongside. Explorers test targets with sampling, trenching and drilling, then measure grades in grams per tonne. At Basin Gulch, Lannister Mining is exploring near-surface gold-silver mineralization hosted in oxides, which the company describes as open at depth and along strike.
Mineral exploration companies acquire mineral rights, collect geological data, drill targets and try to define a resource that could be developed into a mine. Most do not produce metal. Their value usually depends on drill results, land position, jurisdiction and team. Lannister Mining fits this description: it holds the Basin Gulch claims and plans further exploration and resource development.
Many mineral exploration companies work in the USA, from small private explorers to listed juniors with projects in Nevada, Alaska, Montana and other western states. Lannister Mining is one of them, focused on the Basin Gulch gold-silver property in Montana's Philipsburg Mining District. For broader lists, state geological surveys such as the Montana Bureau of Mines and Geology are useful starting points.
An exploration company searches for and defines deposits; a mining company extracts and sells metal. Explorers typically fund work by raising capital, while producers fund it from revenue. Lannister Mining is an explorer at Basin Gulch. By contrast, the four Nevada Gold Mines sites produced about 2.59 million ounces of gold in 2025, according to Barrick figures summarized by Farmonaut.
Near-surface mineralization means metal-bearing rock starts at or close to the ground surface rather than deep underground. That can matter because shallow material is generally cheaper to reach. Several historical Basin Gulch intercepts listed by Lannister Mining begin at surface, including 1.8 g/t gold over 162 meters and 0.66 g/t gold over 326 meters.
Oxide-hosted gold sits in rock that weathering has oxidized, which often makes the gold easier to recover than gold locked in fresh sulfide rock. Lannister Mining states that Basin Gulch mineralization is hosted in oxides. Actual recovery at any project is confirmed only through metallurgical testing, so check company technical disclosures for those results.
The usual stages are grassroots prospecting, target definition, drilling, resource estimation, economic studies, permitting and, if everything works, development. Each stage reduces uncertainty and usually costs more than the last. Basin Gulch already has historical drilling, and Lannister Mining's next stated goal is confirmation and expansion drilling toward a maiden mineral resource estimate.
Mineral exploration drilling cuts holes into rock to collect samples from below the surface, so geologists can measure grade and map mineralization in three dimensions. Common methods are reverse circulation, which returns rock chips, and diamond core, which returns solid cylinders of rock. Basin Gulch has more than 320 historical drill holes, according to Lannister Mining.
Read it as an average grade over a length: here, 1.8 grams of gold per tonne of rock across 162 meters of the hole. Multiplying grade by length gives a rough grade-thickness figure, about 291.6 gram-meters in this case. This Basin Gulch intercept, listed by Lannister Mining, starts at surface, which is why it draws attention.
g/t means grams per tonne, the standard unit for gold and silver grades. One gram per tonne equals one part per million by weight. Basin Gulch drill highlights published by Lannister Mining range from 0.66 g/t gold over 326 meters to 156 g/t gold over 3 meters, which shows why length matters as much as grade.
Trenching means digging a shallow excavation across exposed or near-surface rock and sampling it continuously. It is cheaper than drilling and shows surface geology clearly. Lannister Mining lists trench highlights at Basin Gulch, such as 4 g/t gold and 23 g/t silver over 146 meters, as part of the historical work on the property.
A maiden mineral resource estimate is the first formal estimate of the tonnes and grade in a deposit, prepared under a reporting standard such as Canada's NI 43-101 or the SEC's S-K 1300. Lannister Mining states that historical drilling and new work programs at Basin Gulch will be used in a future maiden mineral resource estimate.
NI 43-101 is the Canadian rule for public disclosure of mineral project information, and S-K 1300 is the US Securities and Exchange Commission's rule for mining property disclosure. Both rely on qualified persons. Lannister Mining's investor page states there is a clear market premium for S-K 1300 and NI 43-101 compliant gold and silver ounces in the USA.
The Basin Gulch property is in west-central Montana, in the historic Philipsburg Mining District. Lannister Mining states it has year-round access from Philipsburg on paved and well-maintained gravel roads and sits about one hour from Butte. The location map on the company property page shows the claim block in the forested mountains of western Montana.
Lannister Mining cites more than 320 historical drill holes at Basin Gulch. The company property map labels historical holes from 1987, a 1989 Chevron program and annual programs from 1993 through 1997. These holes give the company a data foundation that it plans to confirm and expand with new drilling.
The total land package includes 11 patented claims and 53 unpatented claims covering 1,107 hectares, according to Lannister Mining. The property is underlain by a core of patented mining claims surrounded by unpatented claims. The company describes multiple high-priority targets near the historic resource area.
A patented claim is private land: the federal government has transferred title. An unpatented claim gives the holder rights to mineral deposits on federal land while the government keeps title, and it requires yearly maintenance. Lannister Mining says Basin Gulch is primarily on patented land, with unpatented claims surrounding the patented core.
Lannister Mining states that two-thirds of the Basin Gulch property is still unexplored. The company also describes the mineralization as open at depth, open along strike and untested regionally. Future drilling, it says, will concentrate on additional mineralized target areas within the property as well as confirming historical intercepts.
Highlights listed by Lannister Mining include 1.8 g/t gold over 162 meters from surface, 0.66 g/t gold over 326 meters from surface, 3.2 g/t gold over 72 meters from surface, 156 g/t gold over 3 meters and 25 g/t gold over 14 meters. These are historical results the company plans to confirm with new drilling.
Not yet. Lannister Mining describes a future maiden mineral resource estimate that will use historical drilling plus new work programs. The company states the property has potential to host a significant maiden estimate after expansion and confirmation drilling of historical intercepts. Until that estimate is published, historical results should be read as exploration data.
Lannister Mining describes Basin Gulch as an asset that has seen significant historical work and has not been mined out. The historical work shown on company materials is mainly drilling and trenching. For the full history of earlier programs, the company investor presentation on lannistermining.com is the most detailed public source.
Montana is known as the Treasure State because of its mineral wealth and long mining history, and mining still plays an active role in its economy. Gold was first discovered in the Montana territory in 1852 at Gold Creek, near present-day Garrison. Lannister Mining chose Basin Gulch partly for this jurisdiction, which it describes as safe.
Yes. Montana has active exploration projects and operating mines, and explorers continue to work there because of the state's mining history and infrastructure. Lannister Mining's Basin Gulch property is one current Montana gold exploration project, with more than 320 historical drill holes and plans for confirmation and expansion drilling.
Montana is a smaller producer than Nevada or Alaska. According to USGS figures summarized by Farmonaut, Nevada made about 64% of US gold in 2025 and Alaska about 22%, leaving the remaining share to other states, Montana among them. More than 40 lode gold mines in 12 states produced an estimated 160 tonnes that year.
The Philipsburg Mining District, also listed by Mindat as the Flint Creek Mining District in Granite County, is a historic mining area around Philipsburg, Montana. Lannister Mining describes it as the district that led the original US silver boom of the late 1800s. The Basin Gulch property sits in this district.
Silver made the district famous. The University of Montana's This Is Montana column describes one Philipsburg-area mine, regarded as the greatest silver bonanza of its time, that produced $20 million in silver between 1885 and 1893. Public mineral records also list manganese, rhodochrosite and malachite from the district.
Public records for the Philipsburg area include silver ores, manganese deposits studied by the US Geological Survey, rhodochrosite from the Algonquin Mine and malachite specimens catalogued by Mindat. Gold and silver are the focus at Basin Gulch, where Lannister Mining reports near-surface gold-silver mineralization hosted in oxides.
Lannister Mining states that the Basin Gulch property is only one hour from Butte, Montana, with year-round access from Philipsburg on paved and well-maintained gravel roads. Year-round access matters for exploration because drill programs, sampling and site visits do not have to stop for a winter season.
Investors typically look at Basin Gulch for its historical dataset, land position and jurisdiction. Lannister Mining cites more than 320 historical drill holes, 64 claims covering 1,107 hectares, near-surface oxide-hosted gold-silver mineralization and a Montana location. Exploration investments carry high risk, so read company disclosures in full.
Lannister Mining states that US-based companies with NI 43-101 compliant resources trade at a significant premium compared to their peers, and that there is a clear market premium for compliant gold and silver ounces in the USA. That is the company view of the market; investors should compare current valuations themselves before relying on it.

It covers the property, historical work and plans. This site adds plain-language context on Basin Gulch, the Philipsburg Mining District and the exploration stages ahead.
Lannister Mining publishes its investor presentations on the Invest page of its main website, lannistermining.com. The most recent USA edition listed there is dated June 2026. The presentation is the company summary of Basin Gulch, its historical drilling, its claims package and its team, so it complements the facts on this site.
Exploration is high risk: most prospects never become mines, historical results may not be confirmed, and companies often need to raise more money as they advance. Metal prices, permitting and markets also move values. Basin Gulch has a large historical dataset but no current resource estimate yet, so investors should weigh both facts.
There is no single official ranking; the right answer depends on stage, jurisdiction and what exposure you want. Our comparison page sets four companies side by side on the same criteria, from early-stage explorers like Lannister Mining to large producers like Nevada Gold Mines, and explains how each was chosen.
Look at five things: the quality of drill results, the size and security of the land position, the jurisdiction, the stage of work and the team track record. For Basin Gulch, Lannister Mining cites more than 320 historical drill holes, 1,107 hectares of claims, a Montana location and a team linked to K92 Mining and Thesis Gold.
An explorer searches for and defines deposits, a developer has a defined resource and is engineering, permitting or building a mine, and a producer operates mines and sells metal. Lannister Mining is an explorer at Basin Gulch. Lundin Mining, a producer, reported about 77,000 tonnes of copper and 33,000 ounces of gold in the second quarter of 2026.
No. Klondike Gold's Montana Creek placer property is in the Yukon, Canada, near its Klondike District Project in the Dawson Mining District, not in the US state of Montana. Klondike Gold reported 513.1 ounces of placer flake gold in 2026 royalty receipts through October 15, 2026. Basin Gulch is in Montana's Philipsburg Mining District.
Explorers find and define the deposits that producers later build and mine. With US mine output falling from 187 tonnes in 2021 to 160 tonnes in 2025, according to USGS figures summarized by Farmonaut, new discoveries and resource definition matter. Projects like Basin Gulch sit at the start of that pipeline.
Higher gold prices generally make more deposits potentially economic and make it easier for explorers to raise capital. According to USGS figures summarized by Farmonaut, the average gold price rose from US$1,801 per ounce in 2021 to about US$3,300 in 2025. Price alone does not make a project viable; grade, size and costs still decide.
